Intel d975xbx2 memory issue

I have this memory:

http://www.corsair.com/_datasheets/TWIN ... 500C5D.pdf

I have BIOS 2813 installed.

I have an Intel Q6600 quad core. I had it OC'd to 3.0 ghz and it seemed to run fine. I ran orthos to check for stability of my overclock and it seemed to have issues with the memory and proc blend test. I then ran processor only tests and it was running fine. I was playing around with my BIOS settings to try and get a stable memory setting and it wouldnt post. I set everything to default and it started posting fine again.

After a few days I tried to OC to 2.5 ghz and it did the hang post so I had to move the jumper so i could get the default settings. I set everything to defualts and turned off the computer and moved the jumper back and attempted to turn on my computer. I got the 3 beep error message. I then moved my memory sticks from the 2 and 4 slots to the 1 and 3 slots. At that point it would keep cycling trying to post, not even a hang.

I finally got it to post with one stick of memory in slot 1 position. I ran memtest86 through 3 times with out any errors posting. The other stick is in the slot 1 position and was able to post as well. I am running memtest86 currently on it and its on its 2nd pass with out issues.

I am just trying to figure out if i should just keep running memtest on each stick on each individual slot or if i should just RMA the board.

sounds like you have 3 bad slots on your motherboard, but if teh second stick of ram fails, then its a ram problem

The second stick of RAM finished 3 passes without errors, however it was about 70% complete going on the fourth pass and it just restarted it self. O.o

I was able to boot to windows with out any problems with that stick of memory. I threw in the other stick of memory to slot 2 and i got a message saying that my memory was mismatched sizes even though they are matching DIMMs. It boot to windows fine after that message so I restarted to try and duplicate the error and I even looked in the BIOS and the sticks were matching in size.

I have had bad memory in the past and this just seems like weird error after weird error.

What voltage you running? You need around 2 volts for the memory.

I have set the memory at 2.12 vdc. I also have an external fan blowing over the chipset and memory to help keep things cool since my case has poor airflow.

You have tested each stick in a known good slot? Sounds like it's the ram not the MB that's giving you the trouble.
