Sorry I accidently sent the last one in html, so it probably didn't get 
through.

I've run memory tests, and memtest86 v3 gives no errors at all after its 
most thorough testing, I did however find some problems when running a 
test on memtest86 v2.8, however that gave errors on 8 seperate simm 
cards running under two different dual p3 motherboards, I just find it 
strange that they would all fail, I thought it might be the motherboard 
then, but 2 motherboards failing?
