o.k - all systems back up and I had ram tested and ram is 100% fine but here is my problem.
I got Asus A7V266-E motherboard - I bought 2 x corsair 512 266 mem sticks - now if I put a single 512 stick in slot 1 it tests fine and boots system - but if I put both 512 sticks in (configs of slot 1/2 or 1/3) I get major errors but either stick works fine and tests o.k in slot one. I can have a 512/256/256 config making 1gb and everything is fine (making 3 ram slots the A7V266 has) - could it be possible that the A7V266 MB does not like just 2 512 sticks in but would require 3 512 sticks (as I also getting a third stick next week)
any help would be great
