Hi and thank for your help, I just upgraded the memory on this Motherboard from 1Gb (2X 512Mb) DDR PC3200 400Mhz to Patriot Extreme Performance 2Gb (2X 1024Gb) DDR2 PC6400 4-4-4-12 Memory I know that the speed of this memory is twice as fast as the old stuff but I have read and was told when I bought it that it was OK to put faster memory in because it will clock it's self down to the FSB speed. The problem is that I think the processor can't keep up and when running either several programs at once or games my system will Blue screen and shut down.
I think I may need to increase or decrease either the speed or voltage on the CPU or the memory. I do not want to make the wrong adjustments and fry something so can you give me an idea what I should do to try and fix this problem?
I know this is crappy Motherboard but it’s free and the best I can do for now since I lost my job six months ago.

Thanks,
Jim O

Performance Tips
Notice 224 : SMBIOS/DMI information may be inaccurate.
Warning 2507 : Mainboard has too few memory slots. Upgrading the memory may be difficult or expensive.
Warning 2508 : All memory slots are full. Upgrading the memory may be difficult or expensive.
Tip 2546 : Large memory modules should be ECC/Parity.
Tip 2 : Double-click tip or press Enter while a tip is selected for more information about the tip.

Set the DRAM Frequency to 400MHz, and the four primary timings to 5-5-5-16 (DRAM CAS# Latency - set to 3.0/5, DRAM Bank Interleave, Precharge to Active (TRP), and Active to Precharge), along w/ the Memory Voltage to 1.85 - 1.9V. And I don't see anywhere in the Sandra printout you posted which CPU you're running, so assuming a default FSB of 200MHz w/ the DRAM Frequency set to 400MHz, the resultant FSB : DRAM ratio would be 1:2 (200 / 800 MCH Strap) for an effective 800MHz DRAM frequency.
