hi
you need to go in to the bios and set your ram to 533 from 400 that its set at now..
and bump the ram voltage from 1.8 to 2.0 or 2.1 per the specs on the ram heat sink..set your ram timing to 5.5.5.15.
. F10 save and exit..then youll see ram at 1066 during your restart
thanks for your help
it showed @1066 now
i ran MEMTEST it passed 2 tests
but it failed in PRIME95 test
Do you think that it 's good ?
it boots ok without problem
