I tried the adaptive voltage . Offset +0.01V . I guess I know what problem already. The cpu power phase control need to set from standard to extreme and up the frequency to 350khz.

I don't have a good chip like yours. Mine need 1.26V to stabilize for LinX test. cache ratio mine X39 only. Multiplier X45
RAM abit different only.

I used 2 settings for different RAM:

1. 9-9-9-24 1600Mhz 2GB X2.  It is a Corsair Value RAM 1333Mhz

2. 9-11-10-30 1866Mhz 8GB X2. This is Kingston HyperX Fury 1866Mhz.
Both settings yield more or less same result.
