MSI P45 and 4 x 1066 Modules

Recommended Posts

I have the similar situation trying to get the full 8 GB (Same Sticks) to run stable at 1067 for 9 months now. All DIMMS have been tested 60 passes on memtest 2.11 1st slot with no errors so this seemed like the correct place to start. I followed your above suggestions aside from setting the memory controller to 1.3 as I was unsure which setting it was in the bios. I played around for a bit and it was a disaster so lets start from scratch. I finally stabalized the system with the 4 DIMMS (8GB) at 800 MHz. Looking at these settings can you challenge yourself to help me achieve stability at 1066 with 4 DIMMS. Keep in mind it will run fine with 2 DIMMS at 1066 and I'm not afraid to push the board within limits. I will try almost anything to achieve the full potential of these chips .

I split your post off to keep things clear since you have different hardware.

 

Your system may not be able to run the memory at 1066 with 4 modules.

CPU Voltage (V) [Auto]

CPU GTL REF 0 [Auto]

CPU GTL REF 1 [Auto]

DRAM Voltage (V) [2.1]

DDR_REF_A [Auto]

DDR_REF_B [Auto]

MCH Voltage (V) [Auto]

VTT FSB Voltage (V) [Auto]

ICH Voltage (V) [Auto]

 

This is your memory controller voltage. You'll need to tweak it some to try for 1066. Up to 1.35v - 1.4v is safe but I would start lower than that. Make sure you have the most recent BIOS loaded and fully clear your CMOS before you start.
