Have upgraded A8N-SLI Premium from single to dual core.
Went from 3500+ to x2 4400+
Been running great with 3500+ for several months in Dual Channel mode
with TWINX1024-3200C2PRO Corsair DIMMs.
But now with x2 4400+ can only get system to clear POST and
boot with a SINGLE DIMM MODULE in SLOT A1.
How to get both modules in single mode or
both as before in dual?
Can anyone offer some assistance?
