GeForce 7900 Inferno – Burn Baby Burn @ [H]

Not to resusitate a dead thread, but @ eVGA the problem was nailed down to the memory on the card not being able to withstand stock operating temps, especially in an SLI environment. I had (and still have) stock clocked cards, they died. It had nothing to do with OCing (OCing made the probs worse though due to extra heat). Got my cards back and they work. Just saying that maybe someone might want to mention bad memory in the [H] article, was reading it again....
 
if the memory was the real culprit then how come those installed VGA ramsinks on them with proper airflow still experienced problems?
As of now im overclocking also via Nibitor as ATI tool seems to give me problems in exiting 3d mode

Where exactly at eVGA was this nailed down? eVGA still stands by their initial statement that nothing is wrong with the original 7900 series cards and that these new RoHS cards are simply a design revision. In their forum the employees are a bit more forthcoming and helpful, but still stop short of admitting any problems. I can't recall any official statement from eVGA saying the samsung modules on the original cards were at fault.

In fact the memory on the 7900GT doesn't even get that hot unless you voltmod and clock to insane levels. And the 7900GT is the card that experienced the massive number of failures (comparitively speaking). The GTX had some issues as well but the GT cards were dropping like flies as it were.

I am interested to get hold of one of these new revised cards, especially since the rebadged signature series card that eVGA sent me to replace my original GT CO SuperClocked is now failing in the same manner. Unfortunately they have yet to announce replacements for the N565 cards... and I'm hearing it's because nVidia has really buckled down on vendor overclocking partly as a result of this whole mess.

I support your vision that Samsung memory is not the reason for all problems. The Voltage controller for Vmem is also doing its job properly, as long as you have the Mosfet heatsinked.
EVGA and others are trying to tell us that the majority of boards is working properly, and that less of a percent is causing trouble.
This means that you have less then 1/100 probabilty to receive one faulty board, less than 1/10000 probability to receive two faulty boards, and less than 1/1000.000 probability to receive three faulty boards in a row.
I have read at least 10 mails of people who have received three faulty boards in a row.
You will have to produce 10.000.000 boards to have 10 people with 3 faulty boards if the probability is 1/1000.000.
I do not believe that EVGA or anybody else has produced so many boards, ergo the problem is much, much bigger than they tell us.

Whatever the problem is, I expect them to continue on this road with minor adjustments, until the successor of the G71 will be there in september. After that the G71 will be burried.
 
Grrrr...my BFG 7900GT OC from Fry's likes to twinkle in the Bios, freeze in F.E.A.R., and blend Quake 4 w/ the Windows desktop. :mad: :mad:

You know how Fry's can sometimes "bury" things in the back...perhaps I got an old card. Will check em out tomorrow. Maybe I can find a serial number much later than mine, eh?
 
My first 2 MSI 7900GTX's also failed. These are not OC'd boards. They failed, with the same symptoms as others are experiencing with the factory OC'd boards, after 3 runs of 3DMark06 in the Deep Freeze test. This is the only similarity I can find to the problems the community is experiencing. Cooling isn't a problem. The boards idle in the low 40's (nVidia Control Panel) low 30's (Everest Ultimate). Under load they haven't exceeded low to mid 50's (nVidia Control Panel) mid 40's (Everest Ultimate). Bottom line is it looks like a fundamental problem with the basic board and not just the OC'd versions. I now have my second set of these boards installed and I'm praying that I don't have to go through this again.
 
This thread needs pics...I'll go first. 1/1000, eh? How bout 2 for 2? :mad:

These cards are awesome when they work, but I can understand that some people have had the shittiest luck getting such cards. (My eVGA Reloads are still going)

And I was so looking forward to right click-->BAM! :p .net...why?! WHY!? One day ATI/NV's gonna drop the "tweaker panel" with all settings on one page...no scrollbar.
 
A few days ago I bought an MSI 7900gt (with full copper HS), havent tried it yet as I'm waiting for a new PCI-e mobo and e6400 to arrive. The GPU's date of manufacture is 3/2006, I hope its a good batch. Just wondering, there have been so many reviews on the 7900gt, but none have complained about these issues. The only place I'd see these problems are in forums.

I had the same worries when I ordered a XFX 6600gt/AGP when it came out a couple years ago. There seemed to be just as many complaints about those as I see with the 7900gt here, yet I got a good one. Still concerned, I hope my 7900gt will be OK.

The problems with the original batches of 7900 series cards (Samsung memory) didn't show up right out of the box. This is why you don't see these issues mentioned in the various reviews. The cards usually take weeks or months to break down, and that time is dramatically shortened with the vendor overclocked versions. A bone stock first generation 7900GT might last 5 or 6 months, while an overclocked edition card might only last a month.

The new batches of cards use Infineon memory and thus far have proven to be very solid and reliable performers. Most board partners appear to be silently merging the new cards into their existing product lines, while some like eVGA have announced new SKUs for the new cards. eVGA calls them "Reloaded" cards.


I would be lying if I said that this whole thing didn't leave a really bad taste in my mouth. I just did ANOTHER rma on an eVGA 7900GT CO - the rebadged signature series I posted photos of earlier in this thread. This time they sent me a "Reloaded" 512MB card and it's been great sofar. It came 550/755 (1510 DDR) out of the box, but the core is just amazing on it - it will do over 670mhz on the core completely stable without any modifications (other than a Zalman VF900). The memory doesn't overclock worth a darn but that's ok.

I can't help but be worried still, in fact I've been considering selling the 512MB 7900GT and going for an X1900XT or XTX, but my god this card runs great at 670mhz core. :D
 
i picked up a used evga 7900gt ko 584-ar on ebay this week and am waiting for my parts to come in for my new pci-e motherboard.. but that 584-ar should be the later model correct? hopefully i wont have any problems..

Yup, the N584 is a "Reloaded" edition card and is one of the new batch cards with Infineon memory.

Enjoy your card. :)
 
Just a little update my Inno3D 7900GT modded at 1.5v 650/800 with VF900Cu ( full loads at 70C ) is still alive and kicking since July 04 ,2006 only ran it for 1 week with stock and volt modded it after.It still runs fine until now i hope it will never break down..
 
Hi everyone,

this is my first post, and I would like to share my experience with the 7900 GTX series.
Just three weeks ago I bought my new PC, thus assembled:
AMD Athlon AM2 3500+
ASUS m2n-sli
2x512 ICE memory banks (533 mhz)
Point of View 7900 GTX (not o/c)
(hard disks and monitor included, of course).
After a couple of days of perfect usage (during which I was using Open Office and playing silent hunter III and Startopia), I tried to play Star Wars: Empires at War and got the first problems.
Screen would flash during play and several portions of the screen would not be rendered properly.
Since it was a long time since I last played any games on a PC, I reckoned it must have been the usual driver/configuration issue that I had since my playing with my first 486 and didn't give the problem much thought.
I then tried to play F.E.A.R. and the game crashed whilst displaying many artifacts on the screen and the a blue screen message saying that nv4disp.dll (if I remember correctly) had failed, or something like that.
I rebooted and got to the exact same spot as before (2nd level, after you open the gate and there's the little movie when the girls burns the soldiers) and got the exact same problem... only that this time the card died on me: it would display very artifacts even in the bios screen.
I took everything back to the shop and the changed the card with a new one, still 7900 GTX from POV.
I started playing F.E.A.R. again, just to check, and for a while (a couple of days) everything seemed ok. Then I started having problems during the game (occasional artifacts and game freezes that lasted about 5-10 secs) which all would lead to rebooting after exiting the game (the screen would flash).
Since my card isn't (and never was) overclocked, I tried to underclock it through coolbits (as was suggested elsewhere) but Windows always reported that the GPU failed the test.. even when lowering the speeds (both core and memory)... moreover, while trying various settings, it started to display artifacts in the lower portion of the screen (little purple dots, to be exact).
I also installed the latest nvidia drivers to no avail (91.41).
My last try (which I still have to implement) is to by a pci fan card to lower the temperature inside the case, even though I am not quite sure that that is the issue (I don't have exact figures on this, but through the ASUS booster program I have never seen my CPU temp go beyond 55 C; I don't know my GPU temperatures, I only saw them in coolbits after exiting a game that wouldn't crash and were reported at 47 C). The idea came to me since someone said that resolved the problem by installing a new VGA cooler... but I don't dare do such a thing, given my limited skills.
So, to end my LOOONG rant of the week, I just want say that.... I don't know what to say.
From my little experience I can only say that the 7900 GTX made by Point of View have something "that just is not right".
I would change the card and get something different, but here in Italy the seller will refuse to do that, since the new card is not dead...
Guess I am stuck with this faulty card.. something that really bothers me, since I paid 500 euros to get that...
Thanks for bearing with me guys, I just had to tell it all to someone, I guess.
Needless to say, I am more than open to suggestions...
 
Thats just awful man :(

What I do not understand is why the seller refuses to change the card. Its clearly broken and you have tried bunch of different things trying to fix it. I would contact some goverment official who handles situations like these.

Also I think there is a chance you could send the card directly to the manufacturer and get a replacement. Might take awhile, but atleast you would not be stuck with broken card.

PS. Try to stick some spaces between paragrahps, makes reading go smoother :)
 
Well,

on some level I believe that here in Italy it's like the dark ages, when it comes to consumer rights... and I know, since I am a lawyer (even though I am specialized in Administrative law, but I digress).
For example, the 30 days return policy (and no questions asked) people have in the US is absolutely a no-go for sellers here.

So, since my 2nd card is not "entirely broken" (i.e. won't start up or show defect on all levels), the seller won't change it... and neither upgrade it, since HE won't have money back from his dealer unless it's "broken".

I should try and contact Point of View, as you have correctly suggested, but when I went to their site the only "support" I found was a phone number to call... and it's not even free!
No bios upgrade, driver supports only points to Nvidia, and little else.

Things like these drive me mad...

P.S.

Thanks for the editing tip ;)

You could try downloading 3DMark2006 and running the Deep Freeze demo. That seems to push the faulty cards over the edge with some consistency. ;)
 
Hi Every one
I just upgraded in the last few weeks to a Core 2 Duo E6400 with 1GB Corsair RAM and a
XFX 7900GT Vivo Extreme was happy for 3 days :) , then the vertex started in oblivion and 3DMark06 deep freeze caused desktop flickers and display corruption etc you no the story.
So i sent the card back to the reseller and two weeks later got a replacement
Well i did a system reload and all updates etc card was running sweet.... but then 4 days later it all started happening again :mad:
So i contacted XFX support thru they tickets and their recommend the nvidia 91.29 drivers, so i off i go and test them well 3DMark06 now runs but... doom3 gets vertex black spot you cant see thru, oblivion ok BF2 is ok Starshiptroopers last 10sec then crashes with desktop mayhem flickers. So i did an old benchmark 3DMark2001SE lol for a laugh but it whent to explosion of points in pixel spirt test and lost focus and desktop flicker happen as i have read in forums. Well so tried 3DMark03 and the game 2 on wards just goes into a mass of vertex lines every time. (I know the benchmark work fine on XP Pro SP2 with Core 2 Duo a mate tested them all on his 7600GS no probs)
So back to the reseller who are now contacting XFX direct. I just waiting for RA approval to send back my second card due to the factory overclock errors. I just wish this would be all sorted out i am really not looking forward to 2 week wait again :(
 
Demand a refund. Seriously guys...if any of you are considering a 7900GT right now, take a look at the sub $300 19XT's and let it enhance your calm. :D Even if you get a good one, the IQ IMO pales in comparison to ATI this round. Oblivion's a joke with HDR OR AA...must have both! FEAR suffers from uber jaggy roofs and moving vents. BF2 has the ever exciting shimmer line. Those are they only games I've been playing lately, but do you see a pattern?
 
My totally unmodded and running at default Calibre 7900GT 512MB card just died last month for no reason at all :mad:

I was just writing a doc and the screen started to distort, then 5 seconds later all I had was a blank screen

It will be a long time before my very limited dollars are spent on an Nvidia card again................if ever :( :rolleyes:
 
Hi Guys
Well i was told by the reseller to check card with ATI Tools yeah it supports nvidia now.
So anyway i run the artifact tests got none, so i decided to run the max safe overclock just to check out the card and well it whent to 1.9GB on mem :O so i decided to the reset the card back to default value with the ATI Tool. Then i retested for artifacts and got 0 still, feeling like maybe i should give it one more go i tested on 3DMark2001SE and it worked so i restested still working ????, so tried 3DMark03 and it now works to.... so spent the night testing Doom3, Oblivion etc all running fine for the moment,, this a day later and all still fine. I have no idea what ATI tool may have or have not done but i don't care the cards stable for the moment so i am going to enjoy it while i can :D, i will let you know if the issue happens again in case im getting a flukey run thanks for your support
 
Hi guys,

Following my previous posts, I'd like to share with everyone this little piece of info on determining whether someone has a faulty card.

I managed to contact Point of View via e-mail (the address is only on the French version of the site, go figure) and got the following reply:

"Dear sir

Thank you for having one of our products.

We had some issues with incidental cards of this. To see , if you have also
a card , please download the next tool ( freeware )
http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip

This is a HDR stresstest. When this runs ( press D / press 8 for
multisampling 16x / press O for several times until you see a big brown ball
) . when now the card crashes, send it back with the failure HDR errors by
your reseller, and it will be replaced for a good working card.

With kind regards

Point of View / Technical Department"

In my case I tried the test and it immediately froze after displaying the big brown ball.
Maybe this could be useful to other people as well in troubleshooting any problems, that's why I posted this piece of info.

For what concerns me, now I have an ASUS 7900 GTX (that's the only option I got from my reseller). I have locked the fan to always go at 100% (terrible noise, but better be safe that sorry) and I plan to install several Thermaltake ramsinks on the back of the card, including the (in)famous voltage regulator (btw, anyone got a picture showing which one it is?).

I also wanted to thank sam0t and CzarKasm for the help (@CzarKasm, I told the reseller to try 3dmark as you suggested and also the test from POV as well).

Hope this helps anybody (and hope my card holds...)
 
Hi guys
Well the issue i thought ATI Tools had fixed is back again ,, the 3DMark2001SE pixel spirt test is the main one im using to test the card
When it passes card seem to work ok for a while, but when the test has exploded points the card craps it self and will not play Doom3 correclty and more often then not i get display corruption. Plus dismoring after a failed test my screen turn off to no signal for about 5 sec then came back on??.
I am fairly certain it is not power as im am using a Thermaltake Toughpower 600W :)
I read jujujarlo post and tried the test which the card has passed so far, well i have taken screen shots of the display corruption and going to try and get my money back on this card and look into a diffrent model.

I wrote the book there. I'll sum it up here.

After 2 months and two faulty 7800 GTs, I finally got a replacement card for my 7809 GT UDE7 which I thought was a quiet video card compared to my BFG 6800 GT.

They "upgraded" me to the 7900 GT UDF7-something-or-other vanilla card that doesn't have any cooling on the ram modules. Holy mother of screaming fans batman!!! I haven't played any games for too long on it yet, or tested it.

The point is, XFX did have an amazing amount of complaints on their forums. And yes, saying the forums is "too needy" is like slapping the people who had legitimate complaints. The forums had angry customers who weren't getting what they wanted and they couldn't take the pressure.

I was on hold for more than 20 minutes for EVERY one of my 6 calls made to get my card and some satisfaction. And yes, XFX doesn't cross ship, which is out right lazy. The RMA process isn't quick or easy, not to mention tech support insisted any of my quad-12v-rail SLI certified (Thermaltake-Enermax-iStar) PSUs supplied insufficient power to their video cards.

Right now I don't recommend XFX for anything unless you're looking for a good place to get a "ghetto product" with flea-market support. The bottom line is: If you can't handle heat, get the hell out of the kitchen!

I've heard this before, back when the 6800 series was out. That's why I stayed away from XFX. Then I had a HORRIBLE experience with BFG, so they aren't getting my money anymore. Let this be a warning to all of you about BFG. Read about my situation in this thread:

http://www.hardforum.com/showthread.php?p=1029993227#post1029993227

I now will continue to stay way from XFX (because of what I heard last gen and now this) and BFG (from personal experience in dealing with them and also with this recent situation).

I only buy cards made my eVGA, because once again, they have proven that they do care. BFG/XFX just don't want to take responsibility for anything. Companies like that don't deserve ANY business..

I am considering buying an MSI X1900XTX, but I have my doubts. How is MSI? I've purchased two motherboards from them before and they seemed stable.

There is no excuse for seeing these same problems with the next gen nVidia or ATI cards. I hope XFX/BFG actually listen to their customers and shape up, for their own sake.
 
From a personal viewpoint I can highly recommend MSI VGA and motherboard products, they seem to get it right first try with most of their products and the MSI 7900GT is probably one of the very best models ;)
 
Sorry for bringing this back from a 2 week old thread lol , I just Installed my XFX 7900GT and I ran 3dmark 01 SE , it crashed quite a few times lockups that had to be restarted , then it finished one for once and i got a 29103 score , great score and all but it took forever and it crashed alot , its not running hot its only 42C under full load. I have a zalman VF900 Cooler on it and of course arctic silver thermalpaste. it did that on 3dmark 06 too , and it did that while playing BF2 for about 10 mins , and it did that while playing Ghost Recon Advanced war fighter VERY often. Im afraid I probably cant RMA my card as i heard XFX has the worst customer service/return policy and also are the slowest to help their customers on this matter , mine is the lowest overclocked model .. or one of the lowest , its the 470/685 (1370) , after I read the reviews on newegg i was very very hectic about getting this 7900GT , ive had XFX in the past they worked great. but these new XFX/EVGA/BFG 7900GT's all seem to be going down and hard. I want to know if any of you know a good solution to this ? I dont get any artifacting , I just freeze/lockup where i HAVE to reboot.

Also i was thinking it "might" be my powersupply but i doubt it , its only a few days old also , its a thermaltake Toughpower 700, has quad 12V rails , 18amps per rail x4 tho so im not sure if that affects the card in general since theres plenty of amps to feed off of..... but yeah any help would be great... as all of these people went through a tough time as thats alot of $ to spend on a card.......... everything else i got during this upgrade is flawless.. but the card of course.. :( thanks in advance..

Unfortunately you got an XFX card. That means if you're past your return period from the vendor in which you purchased your card, you'll be RMA'ing your card back to XFX and sent another card that will do the same thing.

Why do people still buy from XFX?
 
I dont think i can even return it , as i put a different heatsink on it from Zalman , and ram coolers and I put arctic silver thermal paste on it as well , so that voids the warrenty as far as i know. lol

on another note if theres anyway to downclock this myself which ive allready tried 400/540 that still didnt work , same lockups etc. if anyone has an answer to this that would be great lol. and also my card is only 2 days old. but i still think i cant return it due to i modded 2 parts to it with aftermarket parts. Zalman VF900 Cooler and Arctic silver thermalpaste . so im pretty sure that destroyed any hope of getting a new card even so.

thanks again if anyone can help further on this issue.
 
Why can't you restore it to it's original state, install the stock cooler and apply some sort of thermal paste that is similar to the stock thermal paste. It's not your fault that they sent you a crappy card and since you haven't damaged the card while installing the zalman cooler, I think you are entitled to a refund or replacement card. You might just not let them know about it, it's not like YOU damaged the chip or anything.

I believe it's quite silly that replacing the stock cooling should immediately void the warranty unless it causes the card to malfunction in the first place. People use all sort of cooling with processors and this never becomes an issue. Most of the aftermarket coolers are better at cooling these chips thus increasing it's lifespan and most people who install these coolers know what they're doing better than most workers in the assembly line plus they are more careful when installing these coolers because they've paid major dough for their cards.
 
Try cleaning the back of the card with alchohol and a lint free towel, especially behind the ram and the power regulators, it made my card stable and gave me a higher OC. It helps because dirt can get on the back of the card and cause shorts.

Also, I'm not 100% sure it's your 7900GT, run Memtest and Orthos to make sure everything else is stable. If the card is your problem then you'll either have to RMA it or lower the clocks a bit.

Overvolting it to 1.3V might work as well.
 
hi guys
Abitfan001 if you intrested read my posts :( im afraid i had all the same issue with my XFX card as well. After goning thru 2 of them i gave up and told the place where i got it from i whanted a different maker, so after a 2 week wait (btw it took 2 weeks to RA each card in the first place damm slack) i now have a Gigabyte GV-NX79T256DP-RH which scores 5020 in 3DMark06 the same as the XFX one did when it worked. So after 4 days i still can do point spirt test x 12 runs no problems and Deep Freeze in by 5 time in a row no issues. Feeling much better :D.
honestly i would ask for money back you should not have to put up with a bad product, and yes i whent with thier support line and tried all nothing worked for long. and i agree with you it is not power issue i have the Thermaltake 600W toughpower in my rig nice psu by the way.
So get rid of it only way you going to stop stressing about the damm thing i know from personal experience.
