[Test Report] Powercolor HD4870X2

[RPGWiZaRD]

Thx for the testing. It's quite impressive how on 1680x1050 there's only minimal FPS drop going to AA4x and AA in Crysis makes it look like a whole new game, those screens are really nice. I thought u maybe used some texture mods at first but then I saw 4xAA... Too bad only a few cards can handle Crysis with AA. The temps are much better than I had expected. But I guess you're testing without a comp case as temps on ur GPU tests are always somewhat low so I'd expect for the average user it will prolly run slightly hotter but nice nonetheless.

[mascaras]

i was thinking about temps too low while running atitool (very strange)

so i decided run AMDGPUTool which report temps while playing and with the right 3d clocks & Voltages !

i found that temps are higher compared with temps running Atitool (because atitool are running with 2D clocks & Voltages )




Temps with AMDGPUTool



Automatic FAN (27%)
Playing Cod 4


ASIC Temperature via internal TSS [0] (C) = 93.5º (core0)
ASIC Temperature via internal TSS [1] (C) = 73.5º (core1)


MCLK(MHz)[0] = 900, SCLK(MHz)[0] = 750 ( memory/core 0 clocks )
MCLK(MHz)[1] = 900, SCLK(MHz)[1] = 750 ( memory/core 1 clocks )



----------------------------



Manual Fan Speed = 40%
Playing Grid


00:41:17

ASIC Temperature via internal TSS [0] (C) = 72º (core 0)
ASIC Temperature via internal TSS [1] (C) = 61.5º (core 1)

MCLK(MHz)[0] = 900,SCLK(MHz)[0] = 750 ( memory/core 0 clocks )
MCLK(MHz)[1] = 900 , SCLK(MHz)[1] = 750 ( memory/core 1 clocks )

Do you know if there is any microstuttering? I read a few reviews early on that said it was eliminated, then a friend (who is stuck in the step up program, thus biased) linked me to one that said it stutters. I realize it's almost impossible to completely eliminate micro-stuttering, it can be drastically minimized to an extent that the human eye cannot tell the difference. Does anybody know if they have they fixed it?

Nice report Mascaras

Crysis numbers are far above what some other sites posted, i wonder if a driver issue. IE Tweaktown report 2 x 4870x2 1920x1200 VH = 21fps.

TweakTown was using a P45 which was choking for bandwidth. Not nearly enough to handle these beasts.

only the usual mini breaks in crysis when Saving Game , Big explosions , etc , there is no stutering like 3870X2 @ Big FPS drops !


Grid runs OK

Cod4 runs OK



added Grid SS "in game"

Not sure if you missed my earlier post Mascaras - but is there any chance that when you are done can you run some tests with a 4870 and the 4870x2 in trifire? (that is if you still have the 4870 you tested previously?)

thanks

[cakofony]

You say a p45 chipset chokes this card? I dont understand how it could.

i dont have 4870 anymore


more tests tomorow , already 3:30 AM here !

Tweaktown also used a CPU at 3GHz while mascaras has his CPU at 4GHz

[Xello]

The Tweaktown article claims to use a Gigabyte X48-DQ6, i guess it was the cpu.

Like i suspected it looks like Crysis runs much better with AA in windows Vista then windows XP

btw:

3dmark Vantage results in few minuts

Tweaktown also used a CPU at 3GHz while mascaras has his CPU at 4GHz

woul cpu speed really affect his performance that much?

I could understand the effect of fsb speed, but at such high cpu clocks is it really going to be the cpu that's bottleneckign things?

[Xello]

I notice now that Tweaktown used XP.

I thought 4 way crossfire and 4 way SLI didn't work in xp!

I believe that for quad sli and quad crossfire yes a 3ghz cpu is a bottleneck.

[Slovnaft]

well, ok for quad interfaces yeah. but this is a singlecard crossfire...
oh yeah, i probably should've quoted a different post
i wasn't necessarily talking about the tweaktown review, i was talking about mascaras settings

[mascaras]

Vantage and 3dmark 2006 Results Added !

[mascaras]

I tried record 2 videos with Fraps , but i had to covert them to divx and image quality is not good

also recording with fraps while playing cause a litle breaks , however here they are

Crysis
1680x1050
Very High
AA 4x

possible to take off the fan + fan shroud while leaving the ram plates intact? if so, can you take a pic of that?

thanks

[Astratuner]

sweet i cant wait!

like we did with old HD2900XT to use single GPU waterblock right??

looking to the4870X2 cooler , i think is possible ! (not 100% sure)


btw:


the 2 crysis videos @ full size window

like i said before the image is bad because i had to convert them , the original files are 3Gb (each)




EDIT: Assassins Creed Added !

hey guys.
please help.
i got an engineering sample of 4870x2
the only driver that i managed to install is the one that I got with the videocard, but
its SO buggy that it renders the gpu practically unusable. (driver ver. 8.54-080811n-021649E-ATI)
when i tried to install sampleHD4800X2VISTA8-52-2 (normal 8.52) that is linked in this thread, installation worked perfectly,
but upon reboot, computer is not recognizing driver.
device manager states : "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
also the driver is _not_ digitall signed.
can that be the reason, or is it because I have an engineering sample?
please help(

gpu-z taken on 8.54 -
I've uploaded bios, someone told me that bios was patched and control sum is off. how bad is that? (noobish question, but please bear with me)
link to dumped bios - http://maxsteep.googlepages.com/R700.bin

[maxstep]

can anyone __pleease__ upload whatever drivers and apps (a cd image would be amazing) and a gpu-z bios dump somewhere (mihd.net is a good free method) PLEASE?
because i need to either leave it or quickly try to return it. on vista x64 no driver is installable, except the one i mentioned before, turning on aa in 3dmark vantage gives _mad_ artifacts
can it be disabled because bios is modded? can anyone take a look at mine using TechPowerUp Radeon Bios Editor v1.13 ? http://www.techpowerup.com/downloads...tor_v1.13.html
i desperately need some help ^^

[mascaras]

Hi

im using the 8.52.2 posted here >>> http://www.megaupload.com/?d=U7USVHPY


are you trying to install the driver with a fresh Vista installation ???

A friend mine cant install 8.52.2 neither , only cat 8.7 or 8.54

wait for cat 8.8 Final !!

regards

[maxstep]

hey)
thanks for answering!
nope, bot fresh, but i'm using driver cleaner upon every reinstall, so it should be fine..
do you have any problems running 3dmark vantage under extreme preset?
as soon as enable aa my 4870x2 goes _mad_
can it be because mine is not a retail sample, or just some glitches with drivers?
*sigh* i wish i didnt get this damn one. but for 450cad (no taxes for obvious reasons) how could one refuse?..

yes i can run vantage xtreme ( results 1st page)

hmm it could be both , because is a retail sample or glitches with drivers/OS (maybe drivers/OS)


PS: did you already tried install the catalyst 8.7 ???

[maxstep]

catalyst 8.7 doesn't even recognize the video card (i'm pretty sure its not supposed to, since it is dated 20th july and the launch was on aug, 12)
4870 x2 shipped with 8.52 (8.8 beta i think)
i did manage to install 8.52 by cutting/pasting actual driver folder into the whole unpacked setup one.
i still get _m.a.d._ artifacts in 3dmark vantage with aa on.
most other games are okayish
crysis runs like a charm, just a tad slower than on your rig.
it seems that mine is a plug-and-pray type of device ^^
i _really_ hope that first official 8.8 will be installable on this thingy...
could you dump your bios via gpu-z and upload it somewhere? i would really appreciate it.
