Thanks

Here is the official unlocked ASUS 5850 bios

you will need a bootable usb stick and atiflash 3.75 and use this command:
atiflash.exe -f -p 0 asus.rom

using atiflash.exe in DOS,
atiflash -p 0 filename.rom -f

Got MSi bios working flawlessly.
stock volts I see 900/1124mhz furmark/unigine stable. Got 47.4FPS in Heaven benchmark 1280x1024 windowed, all high 4AF
Stock clocks of 725/1000 same settings yields me: 40.8fps

Did already somebody change the stock cooling for somthing beter? I know that the Thermalright T-Rad2 and Twin Turbo pro would fit. But i beleave both coolers had a hard time cooling the VDDC.

For me MSI 5850/5870 unlocked is the best bios and Afterburner works perfectly. Here is my Sapphire 5850 with waterblock on the GPU only, flashed with MSI 5870 unlocked bios: @1112/1285 - 1.35v:

1.35v, YIKES! :eek:

I got my two 5850's running at 1000/1250 at 1.274v but I'm not going to push any higher than that.

you got 900 core stable with 1.09v?

This 1.35v is only for benching, for 24/7 1000/1200 it needs 1.237v. The main problem for higher numbers and stability is too hot VRM. Look what's happen during Furmark test with VRMs :

That doesn't seem accurate. I would expect VDDC numbers in the 80-100 range with a stock cooler, but that is insane. My VDDC's only reach low 50's with EK waterblocks under full load.

No way that's possible. I'm not buying it. I guess everyone's definition of "stable" is different. About 10 Crysis Warhead loops on Frost at 1920x1200 at 4x AA should show how stable it is.

My first 3D Mark 06 with 5870 :)

Is there a way to set idle clocks?

When I overclock my 5850, the idle clock drops from 400 to 157 which causes my second monitor to flicker.
Is there any other solutions?

U can create a custom 2d clock using msi afterburner. I tested it when i downloaded 1.4 and it works on my 5870

I see these temps only during Furmark test and GPU-1.35v. In all other 3D test and games temps are between 70-80*C under load but for sure I put additional RAM sinks on the top of PCB above the VRM.

Yes, it ran furmark and heaven benchmark at 900 and stock volts. load temp was 60C with 25% fan speed.

EDIT:

I'm on windows 7 with 9.11 and for some reason when I enable ovedrive or use MSi afterburner to overclock. No matter it 1 Mhz or OC to 1ghz, I get screen flicker on my main screen and sometimes my 2nd screen (hydravisioned)

Anyone have this problem while in 2d? When playing a game or something I see no flicker except on 2nd screen.

Nice cooler, is that also made for the 5870, or just the little brother?

is the cpu hsf too big to have it blowing out the back, so that you could use your ddr3 in dual channel.... ?????????

My Vantage Benchmark. Not bad for a Core 2 Duo think I've nearly squeezed out all the performance out of this system. E6700 @ 3.65Ghz & 5970 970/5120.

Wonder how it will jump up once I get a Quad Q9650 @ 4.2Ghz+ :D

Anyone know roughly what clocks a 5850 needs to perform at the same performance as an 5870?
I'd guess 950/1200, anyone got a good idea?
