Hello,
I'm running that combination with an i7-930 CPU and I'll go crazy
If I leave the default settings, sometimes only 6GB, at next boot up to 10GB, and sometimes the expected 12GB will be detected.
The settings for default are (1066MHz and all to auto):
QPI/DRAM: 1.204 V
DRAM: 1.501 V
CPU: 1.184 V
I have tried different voltage combinations.
If the system will be overclocked to 3.2GHz the last stable settings detecting 12GB were:
(All voltages set manually)
BCLK: 200
Mutliplier: 16
QPI/DRAM: 1.23 V
DRAM: 1.52V
CPU: 1.25 V
CPU/PLL: 1.8 V
IOH: 1.10 V
IOH PCI: 1.5 V
ICH: 1.1 V
ICH PCI: 1.5 V
DRAM Timings set to: 7-8-7-24
RAS to RAS: Auto
REF Cycle Time: 88
Timing Mode: 2N
CPU Advanced settings:
C1E Support: disabled
C-State Tech: disabled
Intel Speed Step: enabled
CPU TM Function: disabled
... and if the system will be boot up next day, the same sh*t goes on, detecting sometimes only 4GB next time 6, 10 12 ...
What I'm doing wrong?
