@ gabe = that weird, mine 5870 @ 1050/1325 touch 19K with HSF REF, yours 1060/1300 under 19K ? did i miss something ?

[alex_tpc]

1x5870@1047/1306 as renderer, half a gtx295@760/1225/1523sli-disabled as physx, both on air.
i7 975 on water



I know hwbot doesn't accept pure nvidia gpus with physx enabled but will it take vantage scores where ATI is the main gpu and nvidia is the physx card? hmmmm....

3dm06 score single asus 5870:

This is the guide I followed, except instead of using the Asus bios I used the MSI one to ensure compatibility with MSI Afterburner:

Special Thanks to Overclockers UK

Here is the ASUS BIOS

Here is the MSI one I used:

Here's the latest ATIflash

Here's the tool to format a USB flash drive

Here's the bootfiles I used
http://www.4shared.com/file/43544416...FILES.html?s=1 (Extract them, then make a folder called BOOTFILES, stick the extracted files into the folder)


The Steps

Note: Make a backup of your original BIOS using GP-Z

• Plug in the USB drive that you want to use.
  
• Install and run HP USB Disk Storage Format Tool.
• Select the USB Drive. In the "File system" drop down box, pick FAT32. Tick "Quick Format". Tick "Create a DOS startup disk, using DOS system files located at and click the "..." and direct it to the BOOTFILES folder you made.
• Click start.
  
• Once that's done, copy the ATI Flash and ASUS BIOS into the USB drive.
  
• Restart your PC and boot from the USB Flash drive.
  
• Once it's booted in type
• atiflash -f -p 0 asus.rom (If you're not using crossfire)

I used the MSI one so I went: atiflash -f -p 0 MSI_R5850_unlock.A11

DOS did not like the long name so I renamed the file to something short like MSI.A11
[*]Once the flashing is done will ask you for reboot. When Windows boot you will see all your resolution lost and Windows will detect a new video card. You will have to re-install the Ati drivers again to take effect.

If you're using crossfire, I'd suggest you flash each card individually (For people like Virus). More so that I don't know how to flash more than one card at once



Good luck

just finish flash my powercolor with msi bios , its work great with the afterbuner
Thank u so much

No, no kind of PhysX is allowed on HWBot

[alex_tpc]

didn't think so either but just double-checking

anyways, a bit more push on 3dm06: got it to go over 29K with single asus 5870 on air

[Monstru]

That is a very good result. If you could push juts a little bit more on the GPU clocks, somewhere close to 1100, and push 50-100MHz on the CPU, you could get 30k without sub-zero cooling, which is...cool. Maybe try 100-150MHz more on the CPU with HT Off and see what you get in terms of performance in 2k6

Maybe this particular card memory setting is too high? That would drop the score. I haven't really played with the memory yet; I just picked what seemed to be the sweet spot among users here. At this point, I was only trying to find the Max GPU frequency @ max voltage in order to observe the resulting ASIC and VDDC temps. I locked up in vantage at 1070, so dropped down 10 points, and found what appears to be stable setting for the GPU.

single HD5850 @ stock air, Gulftown @ water, Windows 7 x64

[pr@$r1g]

^^^ wondraful nothing better than this holding a gulftown

I want one Pl..............

hmm ok no problem at all....thanx

RE5 , e84 @ 4.2 GH + 5870 @ 1000/1350

1440x900, DX 10, 8xAA, ALL HIGHEST

[R3DCrocker1]

testing the asus bios under dice and it wasnt stable at all over 1100 so going back to the MSI one

[jeanjean15]

What is the difference between the bios of MSI and ASUS ?

[Gaul]

@ R3d = high score on 2003, mine only 93K

e84 @ 4.6 GH on air + 5870 @ 1000/1250

[Jakethesnake011]

I think the MSi BIOS let you go farther with the clock limts and they work 100% fine with the MSI afterburner utility, the ASUS BIOS let you go to 1200mhz core,a nd 1400mhz memory clock speeds, I flashed to ASUS and having no problem witht eh MSI tool. I like the BIOS and the instruction to flash are very good, and easy to do.

the gddr5 on my card is crap... pretty dissapointed as it refuses to clock above its rated 1250mhz....

meh....

edit... oc Q9550 to 4ghz gave P17584 3DMarks / gpu had no gains 18084 http://service.futuremark.com/compare?3dmv=1513157

[Andrea deluxe]

one question....

whitout increase the gpu voltage whath frequency can get?

[R3DCrocker1]

i can get 960 core at stcok voltage on the normal Sapphire bios but that susing a combo of afterburner and AMD GPU tool.

[xXxDieselxXx]

Getting nice temps at this settings (950x1170 1.2v)

[kite7]

xXxDieselxXx, what cooling are you using for your 5850? I find it impossible to only get around 60c overclocked at 950mhz with the fan speed only at 27% with the stock cooler

[Jakethesnake011]

Whats max safe voltage for the 5870?

[gergregg]

Asus 5850

1010 Core 1250 Mem 1.225v stock cooling

Can you share your bios, please!

[ieatrawbacos]

I just picked up my second 5870. What I would like to see is a beta driver release for XP?

The XP (and XP x64) betas were released the same time as the Vista/7 betas, it's just that no one has bothered to upload them anywhere.

Just register on the AMD developer site and download them.
