BSOD when using 2x2gb G.SKILL F2-6400CL4D-4GBPI-B

I have been using 2x2gb G.SKILL F2-6400CL4D-4GBPI-B
recently 1 stick have issues with my new pc, is all I can assume since memtest returns no errors

always get a BSOD referring to driver irql or kernal or bad pool. When I use only 1 stick there are no issues. It is as if the motherboard just doesn't like 4gb but only 2gb ram.

This has been an issue through 2 previous computers.

Since I can not afford to purchase more ram all I can do is post the issue here and hope there is a solution.

Do you have the latest BIOS for your mobo? If so might raise CPU/NB voltage +.04 and set DRAM Voltage at 1.9

Do not have the latest bios since hav had no bios issues. Already have the ram set to 1.9, did that lastnight trying to get it to accept 2 sticks instead of just the 1. Worked for all of about 30 mins then had to pull a stick after a bsod.
Its really weird...Not a single problem with any customer pc yet my own pc hates me.
