this has been asked before but not answered, is there an asus 5850 bios floating around out there and if so does it have higher ccc limits?

Stock cooling. Just changed the thermal paste by MX2 (didnt really do anything for me, no change in temps ).

Asus bios.

can you post any temps under load and when idle?

And, Shripad, what voltage did you need for that?

**GLENBOY** · 10-07-2009, 10:43 AM

i tried to add the clock limit signature from the asus 5870 to the 5850 but it doesnt work. the signature save or read isnt functioning properly with these newer cards yet.

Anbody getting degraded performance using 2x 5870 ???

I have two Gigybyte 5870 1GB the rest of my system is:

Gulftown @ stock
Asus Rampage II Extreme Bios 0077
3GB of cruical ram
Corsair HX1000W (tested also with Infinity 720W)
Windows 7 Enterprise 64-bit

With one card i get a score of 19xxx in Vantage, but after i install the second card i only get 18K in vantage and 82K in 3DMark03...wth....
Im trying to resolve the problem for the past two days with no luck, i also tried drivers from CD, Ati site and 9.10 beta...?

Both cards run fine when not in CF.

Anybody else got any clue to what to try more?

**destr0yer** · 10-07-2009, 01:04 PM

Try waiting.
Seriously, current drivers are USELESS for Crossfire. Not much you can do about that...
Hopefully the official release's soon.

They are not usless. Crossfire with 2x Asus 5870 works flawless for me.

Tested, Crysis, Crysis warhead, NFS Shift, Operation Flashpoint (new), Fallout , and some other games + all the futuremark "games"

Overclocking with crossfire is no good for me then Can not get 1000mhz on core with crossfire on air. 1 card i get 1030mhz easy.

**GLENBOY** · 10-07-2009, 03:18 PM

f*&% me sideways these 5800 series cards are powerful this is a single 5850 running at default voltys which on the 5850 is only 1.087 volts, wheras on 5870 its generally 1.16,running 820 core 1200 mem at 4600mhz ish on i7,

5870 is 850 mhz core, 1.125v, 1200 mhz ram. At least thats what mine was.

**GLENBOY** · 10-07-2009, 04:02 PM

t think yours is a good one then most 5870's run at 1.16 at 850 in 3d , the lower votage ones are the better so yours is a decent one

ah, I actually had to bump mine to 1.16v to get stability @ 1Ghz

1000Mhz is stable at 1.25v. For 1015, needed 1.27.

About temperatures....
I dont plan to keep the card anywhere close to this :P
So this was done just for benching purpose. Temps were under 70 with fan speed of 63%.

Idle : I didnt check, will be trying to go more today or tomorrow, will report back.

**Jakethesnake011** · 10-07-2009, 06:40 PM

Are you guys using a modded BIOS or the ASUS Bios for the other card to get past the 900 mhz core clock and the 1300mhz memor clock limtis. I have tried to use MSI afterburner and it will not let me overclock past 900 and 1300, I have also tried the AMD GPU clock tool and it has been sucking for me, anything over 900 crashes even with a good voltage increase. I see some using ATI's overdrive and having much higher clock limits something like 1300 core and 1500 memory, can anyone enlighten me on how to do such.

I had to flash to ASUS bios.
AMD GPU clock tool did nothing for me.

Flashed asus bios and card has been flying ever since. It didnt even need voltage bump till 940Mhz, but I had same experience as you before I flashed. AMD GPU clock utility will crash when i set the card at anything over 900/1300.

**Rattle** · 10-07-2009, 07:32 PM

where can i get this asus bios

**Gaul** · 10-07-2009, 08:09 PM

mine v.1225 for 975/1250 with original HIS BIOS

**Stoner@Large** · 10-07-2009, 08:34 PM

msi afterburner isnt working for me, I set the clocks and they automatically got back to what they are in CCC. Any clue what im doing wrong?

You have to flash to the Asus bios first to remove the overclock caps.
