A8NSLI deluxe Memory issues

[Stanman]

I am having problems in the above MOBO running with all 4 slots filled. I orginally had 2X1G corsair value select 400MHZ DC and it worked fine. I decided to fit 512MHZ X2 into the other slot and with a power down and cmos reset it worked fine but win7 would onlu use 2gig but saw the three.
I have now bought another 2 gig of corsair value seelect bit the system will only post with 3 gig. For same reason it will not post with the mem slot further from the CPU filled with the other1 gig slot.

have you tried POSTing with just that slot furthest from the CPU filled with a stick of ram you know works - one of your original sticks should do.

if it doesn't work you may have a dead memory slot.

or one of your new mem sticks is dead.

I did that. swapped memorys around no problem, it booted but its just that slot

Just could be bad luck with the ram you have bought? Would it be a good gamble to buy more expensive ram and try that? I say that as i have put 2 strips in my pc for problems to pop up and when i changed over to better / costlier ram all worked fine. The cheap stuff just was not up to it!
