anyone can give us XFX 5850 black edition ? gpu/mem @ 850/1200 -factory oced-

Hard to open stock fan 5870! I open all screw, but the fan stick too tight on board. What the hell like "glue" it? I don't dare to use strong hand, afraid it damage to the board!

Since this is the 58xx overclocking thread, I thought I'd post my findings with a Sapphire 5830:

Stock cooling + volts (1.15V)= 1030Mhz on core, 1250Mhz memory

vGPU mod = 1.25V + Watercooling on core = ~1100Mhz on core, 1250Mhz on memory

Still working on it...

Impressed with the overhead on stock cooling on the core, less so with the wall I'm hitting when overvolted.

Whta psyhx card did u used?

[skuldarin]

can i state for the record according to the charts on the OP... the 5970 doesn't require 1.25v for 950core / 1250mem...

950core / 1250mem @ 1.175v (Vantage and 06 done at standard matching Performance settings)

After reading this review I got one of these HIS 5850's.

Is 900/1250 on stock volts (1.09v) any good for Furmark settings? I find myself unable to change the voltage though, it might get higher with a little bump. Another thing is that if I apply a setting from Afterburner the card isn't clocking down anymore, is that normal?!

Edit: Must be a new revision of this card, no voltage control available via rt either. So I guess I'm 'stuck' at 900 core.

Hi, is there any other programs for overclocking for 5850 besides AMD gpu Tool? I can't install it because insttool64.exe failes to go through.

MSI Afterburner works fine for me.

Hi

[Cuthalu]

MSI Afterburner works fine for me.

Aye, but it can't go around limitations with MHz.

[p2501]

Did you set "EnableUnofficialOverclocking = 1"?

2x 5870 @ 1010/1300 1.25v and i7 980x @4ghz:

how high are you wanting to go? CCC tops out at 1600Mhz on my 5870's.. can raise it higher if needed.. lol

guys question regarding benching..my card used to bench on 1035/1300 clocks with 1.28v now on my i7 setup 1000/1300 is barely stable on the same voltage and i always get a DEVICED3D ERROREVICE LOST on 3dmark06 sometimes its a D3D9VertexBuffer:Locked error when i test my system for stability the cpu clocks and the system passes the stress test..now i wonder where did i went wrong..

Thanks to Someone who could help..

Curious why does the lowest power state the (157 core/ 300 mem) go away as soon as I underclock or overclock?
Is there a way to fix this?

Hey can u tell me how to do that? I cant seem to figure that part out.
