3870x2 x2 crossfirex drivers update

[purecain]

it would be great if the 8.3cats were coming out this week. unfortunatly the chances are they will be released the same time this month as they were last month...

[rscl]

just a random question,
can I be satisfied with a score of ~13700 in 3DMark06 running ONE 3870X2 and Q6600 on stock settings?

Edit: 18528 3DMarks with Q6600 at 3600MHz...

Not really getting good reports in GPU-Z with my card... 28.8 GB/s bandwidth.
I flashed the newest bios.

New vista cat 8.3 driver up

same old beta. Like really, no patience, or what?

[Riska]

It is not the same got different number than the 2 old betas

[cadaveca]

Is not WHQL, as the real 8.3 will be. is RC3 with new CCC and .inf only. Performance is worse than RC3, stutter is more obvious...higher numbers in files does not make it 8.3, nor does it make it better:


your "8.3" 19877 3DMark06:

RC3 20225 3DMark06:

http://service.futuremark.com/compare?3dm06=5570875

2d rendering is not ok either, with the driver you linked, which was on this forum HOURS ago. This is XS, after all.

[Riska]

RC1 is DriverVer=01/30/2008, 8.470.0.0000

RC3 is DriverVer=02/08/2008, 8.470.0.0000

This sample is DriverVer=02/25/2008, 8.471.0.0000

So something must be diffrent? I dident say it was WHQL drivers and i found it this morning at 5 oclock

[purecain]

no 64bit support in that driver... >M<

[initialised]

Sorry there's no screenies but E8400 @ 3.8GHz on P5N with 4GB DDR2 800 4.4.4.12

1x3870x2 = 17201 3D Marks

2x3870x2 = 19210 3D Marks

on CAT 8.3 using 32bit drivers on 64bit Vista

Pushing the CPU to 4GHz broke 20k

Should be able to see how it stacks up against 9800GX2 and 3x8800 Ultra tomorrow.

Have fun guys!

let the benchmarking beginn

I tested them out and my 3dmark06 score dropped from 18k to 15k! I have Vista64 and a couple of 3870 in crossfire.

[Riska]

Then you must have done something wrong
I have just talked to my mate and he has a 200-250 point raise in 2dmark06 with 2 x 3870 in crossfire and he also runs vista 64bit

[Srecko]

I have a issue, downloaded the cat 8.3 release, installed(CFX is enabled in ccc), but somehow i have a lower score with 3870x2 + 3870(vista64) then 3870x2 alone(winxp).

and i just cannot pass 20k under vista64(did it witho two 3870 in xp), cpu clocks are the same q6600 @ 4100mhz.

its strange, i know vista is not so good like xp for 3dmark, but i have one gpu more....hmmm

[leffe]

Okey thanx for the info. Anisotropic filtering was at 16x at default so that was causing it. Got about the same score as with previous catalysts.

Odd, we got over 20k with a 4GHz E8400 on Vista 64bit, maybe it was designed for 2x 3870x2 and doesn't work properly for 3870+3870x2 yet.

18528 3DMarks in 06 with 8.2
11212 3DMarks in 06 with 8.3
what the hell am I doing wrong? custom settings / let application choose in ccc, although it were the same settings on both drivers unless 8.3 defaulted something "on" which the 8.2 didn't

however I can admit that it looks better, so it might be some setting(?)

plz help

With catalyst 8.3 the gpu does the scaling and not the screen. So if the default 3dmark06 resolution (1280*1024) is not your screen's native resolution then your gpu does the scaling with better image results but with much worse performance. Change the 3dmark resolution to your native resolution of your screen and you 'll see that you have better results, but of course lower than the results that you would have at 1280*1024 without the gpu scaling.So for now on , with catalysts 8.3 and above ,their can't be 3dmarks compare since the gpu scaling plays a very important (negative) role in the results you get.

Sorry for my bad english, i hope you 've understanded.

Personally I unistalled 8.3 cause I had almost half the performance in crysis, and artifacts in cod4 and race07 that i didn't have with previous drivers.

I have a 3850 512Mb pcie and windows xp.

[barfastic]

ever since i isntalled the 8.3 my card has been working great. i used to get 14k on 3dmark, now im getting 18-19 depending on what clock my cpu is running.

I ahve a second hd3870x2 sitting aorund, and im thinking of trying out those drivers you guys sent. Crysis is being played at 40+ FPS, and its quite fast, would love to see it at say 55+ :P

So I ran a few tries with 333 FSB (3006 MHz)
original settings 8.2 - 15969 3DMarks
all max (1920x1200) 8.2 - 9855 3DMarks
original settings 8.3 - 12179 3DMarks
all max (1920x1200) 8.3 - 8158 3DMarks

all max = 8x fsaa 16x anistro etc...
original settings = set resolution to 1280x1024 in CCC instead of 1920x1200
Things got better, sure... but not good enough. Do you think I should use 8.2 for gaming? What is Catalyst A.I. btw? should I have it on? (off atm)

Also I wonder if there's any fix which allows me to run Warcraft 3 with this card, it's completely unplayable... it doesn't lag but the image + mouse pointer is flickering like hell.
edit: if I make a shortcut of the Frozen Throne.exe and add -window to the executive line. it doesn't lag at all EVEN if I maximize the windowed mode to 1920x1200...
edit2: it works flawlessly with -opengl...

[r1rhyder]

yes, turn AI on. It helped with my scores. I see no difference between standard or advanced though.

Hey R1 rider, I'm a R1 rider too What year are you sportin'?

Can someone recommend the best crossfire driver for 2 3870x2 and walk me through a quick setup to get it right. I installed just one for a while and since the single card is considered to be already in crossfire I can't seem to get the 2nd card to work as a single unit with the first!? Doh!

Thanks!

[purecain]

catalyst ai off = crossfire off.... then you have advanced which offers another rendering option besides the normal AFR....

[r1rhyder]

chris, I'm packin a 2007, a sweet machine it is. cat 8.3 + latest hotfix works fine here. drivers are wierd and require a couple of reboots to configure themselves. xp will not run quad gpu's but vista will. are you using xp?

[BansheeAxo]

Sorry, I am running on my computer with 2 x 3870 in crossfire (with p35) yesterday downloaded from the Web AMD catalyts 8.3. But the results were not as expected.
Catalyts 8.1
3dmark 05: 25k
8.3
3dmark 05: 18k

howto install the RC3 version??
