hmm ya i just grabbed another GTX 280 and put it on LN2 and i have the same issue

using E8600

Rampage 2 Extreme

im running at stock clocks (648MHz Core)
and if i raise the core at all even 1mhz i loost 10K points in 3D Mark 2001

If i clock my ram from 1100MHz up to 1375MHz (stock 648MHz Core) I have no problems and i gain about 3k points in 2001

What drivers?

Got my best score uploaded. 13 points behind and crio hasn't even shown his good CL run. I'll be back on top tomorrow to fish it out ;)

im using the Nvidia 186.18 drivers

try 182.50 travis

I agree with punx, My scores went up considerably with the 182.50 drivers.

you mean Rampage extreme :p

listen if you overdo cooling on nvidia they will start to dramatically slow down

so ease up on the temps

I've heard that some GT200 65nm cores had a very low CB (-20°C), could that be the cause of it?

thats not true i have seen many of the 65nm cards run at -170C for instance at the toms hardware us event capt. planet had his 280 at -170C to -190C IIRC
