4850X2

4850x2 9.1 drivers from the amd/ati site. show some small performance gains and add some new multi monitor and virtual desktop functions.
 
eh, it isn't showing up. here is an image link.

Nice score, freaking vista 64 bit wont give my 4.3ghz e5200 anywhere near what 32 bit gave it. :(
 
you think I would get a higher score/better performance in Vista? 64 or 32 bit ? or will Vista 32 perform about as good as XP ?
 
Performance disparities between XP and Vista are overblown, especially with the release of Vista SP1.

Anyone else think it's odd that 3dMark is ostensibly a graphics benchmark, yet it seems heavily CPU dependent?
 
I heard somewhere that the Core architecture when it runs in 64 Bits, lots of optimizations like Micro ops and macro ops fusion doesn't work, that those are optimizations for 32 Bits only, hope that's not true...

That sounds pretty unlikely to me. The CPU's hardware capabilities should be independent of the OS, right?

Yeah it did seem strange to me, I could imagine maybe 20% - 30% of the score being CPU based but it is almost 50 - 60% it seems

There're are independent, but remember that all current CPU's in the market, accept x86 instructions, but internally they work different with their own microcode instructions, x86 simply has 8 registers which is pretty much too low for today's standard. I don't know much about the topic but probably if that was true, may be the way that the x64 instructions are decoded, bypass the internal optimizations for macro/micro ops fussion, but probably isn't needed.

you should check out sp2. i downloaded the rc a week or 2 ago and i am really likng it. even more than win7 (having some probs with my xfi platty and tf2)
 
I have the Sapphire 8.12's installed, should I just install the AMD 9.1's over the top or do an uninstall? I'm running Vista 32 SP1

I don't see the need. SP1 is working well, and if SP2 is in the RC stages, then it'll be out soon enough.

Generally it's best to uninstall the old drivers first.
 
yes, it is a good rule of thumb to remove the old ones first.... I on the other hand did not so YMMV
 
This thread asks how to overclock the 4850 X2 beyond CCC limits, which brings up a good question: has anyone noticed performance increases by overclocking? Personally, I haven't seen it. This might be a function of the 4850 X2 needing to push beyond the CCC overclocking limits, but I'm not seeing any improvement in performance even with clocks maxed in CCC.
 
Could it be a CPU or system limitation? Could it be an bottleneck in the RV770 architecture or a driver issue?
 
I think it might be the drivers not being fully mature with regards to 4850 X2 support. I know ATT chokes on the card, or at least when it comes to overclocking memory past 2000 Mhz. (Read: it can't, because the slider can't go any further.)

Speaking of drivers, Sapphire's updated the 4850 X2's page with new drivers weighing 100MB. I'm going to venture a guess and say these are the same as the 4850 X2 Cat 9.1 drivers from ATi's site.

The HD 4800 already has a high stock clock so even if you overclock it 100MHz higher, you won't notice much difference since it is only ~16% overclock.
 
i used to overclock my vid cards all the time, and i always had problems. i stopped a few years back and not have had a single rma since, except one that was power related. i was getting diminishing returns. a 15 to 20% overclock gave me 2 or 3% gains in frame rates.

I generally agree that OCing in this instance gives very little if any tangible performance benefits, but there are certainly instances where overclocking is worth it--4830 owners, for example.

My scores in 64 bit vs 32 bit are complety different, I scored about 15,900 in 32 bit with lower gpu clocks, lower ram clocks, lower fsb clocks. With 64 bit, the complete opposite of what i said, meaning higher gpu/ram/fsb clocks i was bearly able to score 15,890.

It might be something else, but i will see this weekend when i make a space on my hd for 32 bit vista for testing, since 64 bit does not like the original cod :(

Hahahaha for a second, I was wondering why the hell there was wood paneling on your PSU.... Oh reflections, you trick me again :p

Thank you so much for mentioning that. Those pics were really blowing my mind.

WOOD? in the case? Is he if fraking insane? Oh, wait...
 
This card faster than gtx285? If I oc my gtx285 will it be faster than your 4850x2, or slower?
 
they are around the same. if you overclock your card it will definitely break faster. and suppose that if you overclock your card and it is a little "faster". what is that going to mean 20 years from now? or even tomorrow, for that matter. i wouldnt worry about it. people pay more money for lesser performing cards all the time. its not like you are the first or anything.
 
hey VG, how do you like your 4850x2?

sorry I haven't read every page in your thread, but you're not running it on a 2560x1600 screen are you?

I'm looking @ one of these to run 2x2001fp's and 1 3007wfp hc's....and I like the fact that I can run 1 GPU to run all 3 monitors

thanks for any info
 
I just got my 4850x2, haven't installed it yet...but, so far I am very impressed with its design, especially the metal cover..no plastic ftw!
 
I'm tired of people complaining about noise with this card. The black metal cover comes off.....and the plastic fans are attatched by only three screws. Take off the stock fan blades, Buy a couple 1200rpm yate loons fans, zip tie them to the heat sinks, and enjoy better temps than a 4870x2 or gtx285, and a close to silent vid card.....!!!!!!!!!!! :cool:

That's a little ghetto compared to the Zalman method a few pages back, IMO.
 
If the card is too loud for my tastes, I'll do something about it...but I am very confident that it can't be louder then my 8800 Ultra.

It's just zip tying fans to the original heat sink. I guess it might be considered ghetto, but if it gives you cooler temps, and quiet operation, without having to remove the stock heat sink....it's worth sacrificing "looks."

Compared to using Zalmans, yeah, it is a little ghetto. Definitely effective, but there's something to be said for eggrock's method.

i would kind of have to know the rest of your machine. but for what you explained you would use it for, it should be plenty.
 
I can't get my 4850x2 to work....build is

mobo: gigabyte UD3R
8gb gskill ddr2 800
e8400
bfg tech 800w psu

I cannot figure out the 8pin connector on this card, the 6 pin went in fine, howerver the 8 pin will NOT go all the way in, no matter what I do. I've tried the 8pin to 3pin molex connector, and I cannot get the fans to spin AT ALL....can anyone please help me? I'm so tired and just want this to work.

I plug in my 8pin connector as far as I can, and the board won't even boot...just flicker and shuts down >< and my thumbs fucking hurt so much now.

You might be using the wrong kind of 8-pin. My BFG PSU has a couple of 6-pin plugs with an attachable 2-pin plug to turn it into an 8-pin. See if your PSU has other 8-pin plugs and try those.
 
Nope, it's got just the 1 8pin connector, 3 6pin connectors and 1 4 pin connector. I'm going to go Fry's tomorrow and take a look at some adapters maybe. I just hope all of my pushing and pulling on the card hasn't fucked it up.

Quick question, I have an adapter that is an 8pin with x2 3 pin molex connectors on it, it goes in np..I plug the other 2 molex to the PSU, and get nothing. Defective card?
 
It could be a bad plug socket, yeah. Might want to return the card as defective and get a second.

This is the first we've heard of any such problems with the card.
 
Aw crap. I booted my PC up a little while ago, and I've got the dreaded Code 43 error.

Anyone know what causes this and how I can fix it?
