how does the timming issue affect ram performance in relation to the bios. Could the Ram have a certian timing that the bios is not recognizing and has to be manually entered? It seems like them more sticks I out in, the qicker the error. If I have just one stick in, it never crashed. Soes this look like a timing issue?

Also, I have a 1000 watt coolmax that seems to be working. It works fine in another computer anyway. That 500 coolmax simply crapped out less than three days after using it. POS

The Mb is a Asus P6T V2 and the memory is Buffalo Firestix 1600. I think the memory is older than the MB. The first edition of the manual is December of 08. I can remember reading posts about the memory  that were posted in summer of 08.

ok, here is another question. The specs on the memory are 7-7-7 2.0V. If in the manaul it says.."According to CPU specs, DIMMs with voltage requirements over 1.65V may damage cpu permanently. We reccommend you install the DIMMs within the voltage req below 1.65v."

Im reading form the CPU/DRAM Bus overvoltage setting section

My suggestion:

Sell the Buffalo and purchase something from the PVL.

Well, I think I may have solved the problem. The memory was Buffalo Firestix Inferno. A really high performance memory that required 2.1V. It was operating at the default but it could not have gone higher than 1.7 with the auto DRAM on. I had to manually enter the voltage in the bios and change some jumpers around. It originally was unstable at 2.1V 1600 so I down volted it to 2.0 and lowered the memory to 1333 and its working fine. I'll try messing around with it later to get the right balance to get the 1600 out of it. The low voltage thing (recommended is 1.65) was enough to power one stick, but not three.

Thanks for all the help.

Along with your motherboard documentation, the Crucial website (www.crucial.com) is a well known resource for determing the correct memory specs of a computer or motherboard.  None of the memory they sell or recommend for your motherboard exceeds the 1.65v limit mentioned above. 

Good luck with that...

I see that Intel recommends a limit of 1.65 but even in the preferred vendors list there voltages up to 2.0. It stated that you may need to have some super cooling system to go above 1.9, which I do. I ran some burn ins and never saw core temps above 68C.

Super cooling system...  Okay then...  I was wondering why my lights dimmed whenever you fired up that system!

You and your system are operating way beyond my level of knowledge and experience.  It's time for me to quietly excuse myself from this thread...

Just an update to all those who helped. Its been three weeks and the system is running stable. I had to modify the MB jumpers to allow overvoltage of the memory. I have it at 2.0 volts and down clocked the memory to 1333. everything is fine. I may try to mess with it to get it up to 1600 but Im happy with it now. Im not sure an additional 267 would make that much difference.

Thanks to all those who gave me advise. It turns out the memory is just fine. Glad I didnt sell it! The system cooks! I love my new i7 920!
