Core i7-965, Rampage 2 Extreme & 4870 X2 CrossFireX

[Sampsa]

Hi,

I did some first LN2 testing at home with Core i7-965, Asus Rampage 2 Extreme (retail) and 2 x Asus EAH4870 X2 TOP:



Some insulation around LGA1366 socket. Used two OCZ and one G.Skill DDR3-1600 module.



Scaling of this Q1CK Engineering Sample CPU seems to be very bad. I could run easily 4,4 GHz with 1,45V and -20C but 4,5 GHz needed 1,55V and -50C.. after that I hit a wall. CPU-tests crashed almost immediately.. 4,6 GHz was no go. Multipliers 34x and 35x didn't seem to work very well, lower temperature didn't help, more voltage didn't help. I got stuck.

I was able to score P27491 in Performance-preset.



P18530 with single card (850/990 MHz).

I'll continue testing so more coming soon
