BFG 7800GTX problems

Zero-fill the fucker and then reinstall Winbloze. It's the best thing to do to rule out any software conflicts and the like. If the PC still keeps acting up, then you'll know for sure that something is definitely wrong (hardware-wise). :)

I agree, zeroing the HDD with it's respective low-level formatting utility (available as a floppy iso on each manufacturer's website) really improves an old drive's performance if it's all borked up.
 
wow, it started being stupid again.

my pc froze about 5 times lastnight, like 3 when playing BF2, and twice when playing WOW.

well, ill go disable APIC, but what does it do? my setting above it is S1&S3, wahtever that means...
 
well i disabled APIC and then my pc wouldnt load into windows, would get pass the bios and just be blank, then i restarted and it gave me options for safemode, load windows normally, or revert back to last good config. so i just hit load windows, and it froze, or atleast just sat there. so i restarted again tried it no luck, so i change it back to enabled.
 
OK do you have these things?

-Latest BIOS for MOBO
-Latest Nforce Drivers
-Latest Video Drivers
-All windows updates
-Latest version of DirectX

Also, my suggestion would be to re-seat EVERYTHING in the PC, including the CPU. Yes I know it is a pain in the ass but try it.

Also, if you have the ram in slots W and X move it to slots Y and Z and see if that helps.


IRQ_NOT_LESS errors usually mean RAM issues or overclocking.
 
yes, i have all the latest updates for everything.
havent gotten that irq_or less error thingy...


Ill have to re-seat everything on sunday i guess if i have time then. thanks for the help though.

btw: not overclocking, and this issue was happening with my old RAM.


is 1.39 - 1.4 a decent vcore voltage?
 
fodder0:
sorry to hear your problems have started again man... that sucks big time.
If you disable APIC you need to reinstall windows. But i would recommend you dont disable it.

Im going to try a few things on my machine this week and see if it fixes anything. see how it goes.

reformat your pc man, and resintall windows. it pretty much fixed my problems, still freezes occasionally, but it only has twice, but hasnt in like a week now with heavy game usage.

I had done that a while back and it made no difference at all. I actually did it twice with no added cards installed and it still did it. As for the IRQs, after both installs I reinstalled the cards and newest drivers and they went back to the original IRQs with no change at all.

Im still going to lean towards the PSU. Reason being is that my system,from the calculation that I made,is right on the edge as far as wattage goes. My PSU is a 645W and my calculations say that my system is using around 630-650W with all I have installed. Take into account the fact that the system is running at room temp which will lower the overall effeciency and now i have a 450-500W PSU.

Also, Im pretty sure that the 12v rails on this PSU are not supplying enought amps to the systems. Dual 3.4 Xeons, 7 SATA drives, 2 of which are Raptors and all the other little goodies might be looking for that 850W PC Power and Cooling PSU.

FYI, I have tested all the HDs and they are all fine. My OS is loaded on the Raptor so speed shouldnt be a problem.

Guess I will have to bite the bullet and get that new PSU and let you guys know how it turned out :) If you guys think of anything just keep this thread goin so we can help everyone out.
 
I had the same problem with the Asus Sli board (alienware computer). It started locking up 20 minutes out of the box. Their tech support could never figiure it out so I sent the whole thing back. I has the Pc power and cooling power supply so I dont think that is the problem. I would look into a bad motherboard.
 
fodder0:
APIC basically handles all your computers IRQ's. You turn it of and you get alot less IRQ's to use and things start not working.
If you have a dual cpu system then you MUST have APIC on. Shit just wont work with it off. And either way if its change you need to reinstall windows to work with the changes.

http://www.extreme.outervision.com/index.jsp use that to calculate what sort of PSU you need.
Im am certain it isnt a power problem. Because you are having the same issues as me, and i have upgraded my PSU to 680W. And it made no difference.

jn1167:
You should test your problem, by uplugging all uneccessary devices from your PSU... take off as many HDD's as you can and just run a game off the raptor for now. So basically try and get your PSU load as low as possible and see if it still locks up.
Maybe even go back to a single 7800 for the test.
Depends or you could just buy a new PSU and then find out it wont make any difference. Have you checked your vaultages? Are they within safe limits?

I would be looking elewhere also If I had that PSU in this system but I have the PSU that came with this case.

As far as a bad Sumpermicro server board, I have been building servers and workstation for a while using only those boards and I have yet to run into one that was faulty so Im not quite ready to blame the mobo

Guess Ill keep trying till this new PSU gets here :)
 
Hello Ladies,
same problem here.

It´s not a problem with the PSU.
And it is no heat-problem. The nVidia-Chip can handle more than 115°C, and then it starts throtteling like the Intel P4s.

Since I have a XFX 7800GTX Overclocked/ Extreme Edition, running with 490/1300Mhz I have the same stuttering in games like BF2 with these strange freezes.

I checked this event-thing, where I found the Event-ID 51.
It was a broken DVD/RW.

Try to clock down your cards about 20Mhz, and you won´t have any problems.

Please check and comment.

But you are not al
 
TinyRK:
Funny you should say that as i have had it freeze twice withing windows now, once while trying to burn a DVD.
How exactly is clocking down the card by 20mhz going to help if its a broken DVD burner thats causing the weird crashes? Atleast thats how i read what you said.

I dont thinking clocking down the card is an answer as these cards should run as they are sold, clocking down just means there is something wrong with the cards. But then again i have had 2 crashes in windows which indicates its very very very unlikely to be a video card problem.

The other thing is when my system locks up, beit iin game or in windows, the num lock key still works, and those are run purely on software which means the OS has not compeltely locked up. Which is weird.
 
Ok DaForce,
but your problem is another than mine.
I have only freezes and stuttering in games, not while burning DVDs or just surfing around.
And therefor it works! ;)

Sorry for my missleading information.
 
hehehe thats ok.

I have only had my computer freeze in windows twice now and only in the last fortnight. out of all the times my computer has freezed. 95% are during gameplay. only 2 in windows.

I will try de-clocking my card and see what happens, but my card isnt an OC one anyway, but will see what happens.
THanks
 
What exact model RAM do you have? What's your RAM voltage set at? Have you tried running Memtest? What's your CPU voltage/clock speed, etc?

I only ask because some Corsair RAM is supposed to be 2.6v, others are supposed to be 2.75. You could try upping the voltage to 2.8 and see if that help your stability at all.

If you still can't figure out your problem, I would suggest heading over to DFI-Street since you have a DFI board.
 
joeshmo1985:
Ram is as stated in my sig (2x1gb) not sure of voltages at default at the moment.
Cpu is at stock speeds to 2.2ghz, also not sure of voltages. But at default and havnt touched them.
I have run memtest and zero errors.
I dont think its the CPU or the MEMORY or the PSU as they have ALL been change since this started happening.

originall i have a athlon64 3000+ 1gb of corsair ram (2x512) and a 550w antec, now i have the parts listed in my signature.

I used to run the athlon 3000 @ 2.6ghz, which meant that the cpu and memory had their voltages increase slightly. It was locking up then and also BEFORE I overclocked that CPU.

Also if it were ram i would have thought it would have been more reptitive. this is totally random. I can go to a mates place and play games for ages.. without it crashing. So im at a loss. But will give anything a shot.

Whats the url for dfi street.

Also I have bought a raptor for my OS so this week i will be reinstalling windows XP Pro this time (now i use win2k) and starting off using the latest drivers instead of updateing. I really really hope its not hardware, because its a pain in the ass taking everything out especially if its te motherboard.
 
DFI-Street Link:
http://www.dfi-street.com/forum/index.php?

I'm assuming you have all the motherboard connections(12v,5v,HDD,FDD) plugged in? I also assume that you updated your bios to suppost your X2 chip? The thing I would check is your RAM voltage. There are a bunch of different XMS series sticks on newegg, most of them state that default voltage should be 2.75. I believe default on your mobo is lower than that. Go into the bios and set it to 2.75v if you can, 2.8 if not.(Note: should you fry your RAM I won't be held responsible. Check the exact model on newegg first and see what the default voltage should be, odds are it's 2.75.) Of course, since you've run memtest with no errors this may not help at all, but worth a shot. If your lucky the problem will fix itself after the fresh install, if not, check out DFI-Street. Make sure you get your entire rig(including bios version) in your sig over there and post in the NF4 forums. Good luck to you.

Edit: For a while my computer was freezing randomly as well, but I had it overclocked. Didn't have enough voltage going to the core, but since you're not overclocked(and since your old CPU was) I doubt this is the problem.

You also may want to try making a new thread in the "General Hardware" forum here for your specific problem, you might get help from different people who may have ahd similar problems. I would recommend it as well as DFI-Street.
 
Thanks for the link dude, but after realising how lazy i was to even ask i found it myself :) Having a browse now.

At the moment i only have the 24pin plugged in (obviously) and the 4pin 12v plug, not the other 2. Do you really think they would make a difference, or is it a "cant hurt" type of scenario.
I will up the memory to 2.75 and see if that helps, but like you said i doubt it will do jack.

Thanks for you help ;-)

I will do the re-install *shudder* which I am NOT looking forward too... in the next day or so. And if it still crashes you will know because you will hear me scream :mad:
Heheh will update in a few days unless news comes sooner.

<edit> i have ntune installed but i only use it to check temps occasionally, i read somewhere that could cause problems. Should i uninstall it?
 
If you're really shuddering at reinstalling windows, that probably means you really need to do it.

XP and/or 2000 are much better than previous versions about cleaning up after themselves, but stuff still builds up, especially after you've done your 15th video driver switch trying to fix a problem.

I did an OS rebuild this weekend as part of a new rig, wasn't that bad a deal at all. I just backed up all of my important stuff to a non-raid partition and then kept that drive from being used by the install and copied my stuff back. I did have to reinstall a few utilities, but not that much.

I really like Steam on a rebuild like that. I don't even have to backup the games or anything, just reinstall the steam client, login to my account and have it download the games again. Liked it so much, pre-ordered day of defeat:source last night, to play tonight. :)

I played half-life 2 on bfg7800gtx oc SLI at 1920x1200 max eye candy for the first time last night and it was pretty much a new experience.
 
Well my last reinstall was only a month or 2 ago (maybe 3) when i first got the computer.. I shudder just because its just annoying to have to do thats all. But i will cause im getting a raptor for my C drive anyway, to replace an older 80gb. So either way its gonna be a huge improvement.

Yeah BF2 is great. Just had a play then, 1600x1200 with max everything 4xAA and 32 bots.. running lowest of 55 and highest of around 80 on zatar wetlands... looks great.

Just made some changes in the bios upped my voltages for ram and cpu (were abit low before) and also update my video card bios to the OC one. Will have to see how it runs over the next day or so before i reinstall on the raptor.
 
I having the same problems with my new BFG 7800GTX :( I had an 6600GT and things were running fine. The problem is not heat since my temps @ idle are <49 and 50-70 load.

The performance is great tho, running BF2 @ 1600x1200 all high at constant 60FPS and DoD :S all high @ 1920x1200

Might just try reinstalling WinXP on another HDD that I have
 
Hey Mate, no need to bump. Replies sometimes take awhile in here :)

Well i had a tinker in my bios and locked in the proper voltages for my cpu (not auto anymore) and also proper voltages for my memory. I turned off errata 123 as i heard that might cause some problems, and I also updated the bios of my video card to the OC one. Computer seems to definitly be running better, but i have yet to reinstall windows on teh raptor, that may have to wait till the weekend.
Have played about 30mins of BF2, and about an hour or 2 of Fable and no lockups yet, but this certainly isnt a sign either way as I have played games for longer before without it crashing. I will try splinter cell Chaos Theory tonight that seems to make it lockup rather quickly normally.

Also how is DoD: S ? I bought it but havnt had the chance to download it yet. Is it OMG OMG OMG OMG ?? :)
 
Regarding DOD:S Crank it in 1280x1024 or higher with full eye candy and the HDR and it's pretty sweet. I really like the sound effects, real time background sounds really add a lot I think as do the sounds of the weapons themselves. They sound powerful and it makes me want to use them. Now maybe if they'll release more maps soon that'd be nice. The gameplay is tried and true, but simple things like the notification when capping a flag is much better. I also love the new RPG on the rifleman class.
 
Well, the format didn't fix it and now I'm getting "memory could not be read" issues with HL2/DOD:S/CSS and Windows wont activate.

Oh, how life can be great sometimes.
 
By reset you mean what? Anyways, I reinstalled DOD:S and I've been playing it all weekend with one freeze. While the computer was frozen I opened the DVD drive (Just trying it since someone on this thread said that he had a broken DVD drive) and the computer came out of the freeze! But as soon as I closed the drive it froze again :(
 
i mean, take everything apart and put it back together basically, and reformat. try installing just a few parts at a time, not all at the same time.
 
FYI, after changing all my bios settings to get the voltages right (they were set abit low for my cpu and ram bydefault) my machine still froze ( i thought the bios tinkering had solved it)

I have no installed Windows XP pro SP2 on a WD raptor ;-) and will make the final change over to it this weekend. I dont know if that will solve the problem, but I sure hope it does. If not I will RMA either my video card or the Motherboard. It has to be one of those causing the problems, and im thinking the video card as its the only common thing amongst all the posters here.
 
What about it?

You think thats why might be causing it?
It has frozen twice in windows as well. But 99% of times it freezes in games.
And the other day when it froze while i was playing splinter cell, i took some of the advice floating around that it might be a dicky dvd rom drive, so i ejected the splinter cell dvd and then put it back ain and then the screen went blank... thats never happened before so its like the drive had some effect.

Another thing i was thinking about, is most of the time the games it locks up in is games that use the Starforce protection scheme, and therefore need the DVD in the drive to be able to play them.
So im kinda half thinking it may be the DVD rom after all.
Well i will wait and see if it locks up at all on the new raptor XP install then start unplugging things, and if that fails i will whip out the Audigy and use the onboard sound for awhile.
 
So the cause of all our problems may very well just be a dodgy DVDrom drive.

Damn thats annoyingly not obvious. hhahah
 
I've seen faulty optical drives do really weird things to computers. They can cause all sorts of problems with your system that you'd never think to associate with a flaky drive.
 
mmmm ok.
Well so far it hasnt crashed while on the XP install.
Will have to wait and see.

Mind you my DVDrom drive is about 3 years old... might by time for and upgrade anyway. hehehe
