UnOfficial Asus Rampage II Extreme Thread

[rurik]

Cryptic,szamz.
thanks,1.45 i think is ok.my ripjaws need 1.45 qpi at 1950mhz,but 2000 i cant manage.
i think,its motherboard problem.
i rise up to 1.50v qpi,but cant stable this sticks.
and second,i also have evga x58 sli3 mobo,with this i stable at 4.2 with HT on and memo 1600 without problem.with rampage i only have 4150 with HTon and memo 1550 or 19xx(dont remember).
i trying everything,but linx crashes more,than 4150.it not chip,i know,its mobo.my previus mobo was RE 775,it was great mobo,but this one...i dont know.
with evga was too easy overclock my chip,only cpu voltage and qpi voltage,other was on auto.
with rIIe it was harderer,same riseing cpu and qpi voltage,but chip not stable...
one thing,with evga was one gpu hd 5850,with rampage i trying sli with two gtx460.may be this is a problem?
thanks for the replys,my brain is stuck...
