I appreciate your help! There is NO stupid question or answer...as far as I am concerned ANY help is always WELCOME help...THANKS So, yeah being from the i386 world, I am also aware of the timing quirks in the intel world. The CPU is a 754 pin...specs below..hope this sheds some light on the situation...if anyone wants me to throw up some debug info let me know!!

When looking at 939 pin AMD CPUs, and what memory to get, I noticed that for one major quality RAM maker, the timings they recommended for Intel CPUs were faster than those they recommended for AMD CPUs and your figures look eerily familiar. It was something like 2-2-2-5 for Intel and 2-2.5-2-5 for AMD. I'm no expert on RAM, but your error does sound very hardware related. Can you check the RAM manufacturer's web site to see if they say anything? Also, some motherboards can be very picky about RAM. Is it worth trying with just one RAM chip? Does the machine POST ok with full memory tests on? (It doesn't prove anything, but if a chip is really duff it should find it). A little heretical, I realise, but is there the possibility of trying another OS (Windows, Linux) just to see if you have the same kinds of problems? I'm not copying to the list because I'm no real expert on this kind of thing; just stuff picked up from background reading. If you try any of this and it works can you post back to the list what finally worked? Best, --Alex
