Yea I didn't even know they exsisted...there was no mention of it being 256 bit on the site nor is there now. Oh well live and learn...can't complain though the card works good and real good for the price! There doesn't seem to be a great deal of info on these cards yet for O/C (bios and voltage increase) hopefully it won't be long...see if I can kill another one... LOL

Tought I just share a pic of my (homemade) cooling of the VRM area.
Coooler made of an old Athlon heatsink. Recommend a non conductive paste between the cooler and the mosfets. (AS Ceramique).

Initially I had hoped this was sufficient, but had to add a 80mm afterwards.
Temps around high 50's (Celsius) after 2 hours Crysis (900@1.30V)

So if you have some spare time..

Nice! Hey I also noticed that the pulse chips between the mem and the sinked VRM stuff) get VERY hot, especially the lower one. May be worth sinking that stuff as well....

Very nicely done.

I noticed that too and put coolsinks on them already a few weeks back . (i even thought for some time that those chips where the Vregulator chips , because anything which becomes so hot can't have a heatsink on it i thought

It didnt help anything , they keep getting incredibly hot .
Then again , my heatsinks where smaller than the pic above , also i used thermal pads to stick them on .
A 120mm is blowing over them .

core volts?

**Martin.v.r** · 01-06-2008, 05:52 AM

core 941 = 1.35v

MOM

ned toll to timingset can get over 981 on mem

in 05/06

is that a hard mod, for the volts?

EDIT: and that new results is impressive

**Martin.v.r** · 01-06-2008, 06:44 AM

no hard mod

set volt in atitool 0.27

ah OK, so you are putting up with the having to set clocks and then voltage afterwards nonsense? :P

EDIT: if I set clocks higher than ~870, the comp crashes, regardless of how volts are set before hand, since I assume it jumps back to 1.15v on setting the new clock. how do you get around this?

**Martin.v.r** · 01-06-2008, 11:39 AM

it helps if you bios flash to 1.2v ind 3D
1 set clock
2 set volt
in ATItoll

Then you have more room to go up. When I set 1.25v in atitool, 833 was not stable (yes I know to do voltage after clock speeds), but when I did it as a bios mod, 833 was stable. I'm on air BTW, moving to water very shortly for both CPU and GPU.
