9000 series are pain with the coldslow.

That's funny, that is the exact core I could reach with mine. Eventually just had to give up. Shutdown at around -45c every time. I tried to epower hoping it would bypass something but it didnt help. Someone mentioned trying to disable temperture monitoring but I couldnt find the ic and didnt have enough knowledge to figure out. Was so annoying because I spent so much time modding, firt vid mod and then epower.

I can bench up to 1100core @ -49-50c but it is on the verge of coldslow so i did not took the chance.cold shutdown can be hardmodded but coldslow is in the bios.i have spent numerous hours trying to find how to properly play with these cards.

The 9600 gt i benched has coldslow also at -45 and it is pain.

I wanted to try mod the bios, but the one cold slow bios for 9800 ref card linked on hwbot is exactly the same as one of the "stock" bioses on TPU.

I can't find the "before" and "after" of this exact bios, so can't understand what is changed exactly, comparing with HEX editor.

ya I was trying to figure out how to hardmod the cold shutdown but figured I would hit cold slow if I went past that temp anyway, so I didnt go any further and just moved on to 8800 gts 640mb.
