Weird it works fine in another system one stick at a time and both at the same time.
I tried it in my other system after I posted here, and seems to be ok.
My MB for the one that doesnt work is a Soyo k7vm333, the Ram is Kingston and shows up on their spec sheet as compatible.
the one it works on is a A7N8X-E
Could changing the ram make a problem with windows? or is it bad ram?
just weird how it works in one not another.
