Here is the situation. I have built a new rig using:
Gigabyte EP45-UD3L mobo
8 GB OCZ Platinum DDR21066
Intel C2D E7400
Antec 500W TP PSU
Right now the machine is not overclocked. I have verified in BIOS that the system is at default speed and the ram is running at 1066 (default).
The system is having BSOD after BSOD. Different errors, but all relate to memory.
Memtest86 will freeze the PC at 5% with all 4 sticks in however, each stick tests out fine individually in each of the 4 slots.
I have tried all combinations of chips in all slots, any order of all 4 chips freezes memtest86 at 5% completion. Any combination of 3 chips freezes it at 7%.
I have set the memory to factory voltage and timings. I have tried underclocking the memory to 800mhz instead of 1066.
The weird thing is that all of the combinations of 2 chips works fine except one combination. c2 + c3 in a paired slot causes an immediate crash, but all other combinations in slots works fine.
The symptoms seem to be that ANY more than 2 chips causes memtest to fail. Even though each chip tests fine alone and in most cases with 2 chips...
Finally, I have 11 successful passes of memtest using c1 and c4 in slots 1 and 3, but then in windows, another immediate BSOD.
Please help, I'm losing it.
