Gigabyte N650SLI-DS4 and 2 ocz2p1066gk sticks

Hi everyone,

I have a odd issue that just started today. When I went to power on my machine I had a long beep which according to the MB manual indicates a DRAM error (Gigabyre N650SLI-DS4).

I have two ocz2p1066gk memory sticks 2GB each which I had in the red banks for dual channel memory. I removed one stick and then the other to see which stick was bad. Each stick separately posted. I then tried to switch the sticks each one by themselves and it posted. I tried to put back both sticks and I got the beeps again.

I then proceeded to run a memtest on each stick in the first bank. Each one was clean on the first pass.

So I decided to bump up the memory voltage by +.1 and with both sticks in and the system booted! The memory sticks are rated at 2.1V so I'm assuming that it would be best to increase it by .275? If I select .3 the option is in red which I would assume is not a good idea.

My system locked up after a few minutes with the +.1 setting. Does anyone know what the problem may be? Do I need to go higher on the memory voltage or do I have a memory/MB issue? The memory has been running on automatic for a few months without any issues.

Edit: I set the settings back to the default and then ran another memtest. I got about 15,000 errors. I am trying to run memtest on the 3rd bank (2nd red bank) to see if I get the same errors.

Edit 2: I sat the two memory sticks in slot 2 and 4 and received 2 errors on the first pass. I'm going to run a few passes in the first bank with each stick to see which one may be bad but it is looking like a memory controller problem?


Thanks
