If you have tested both memory stick separately in slot one, and they throw BSOD, return MOBO. You said you bought it 3 weeks ago.
Do they refuned me 100%? Sorry i've never RMA'ed anything before.
Do you have warranty on your mobo? If you do, they should refund or replace your mobo.
Yep still have the reciet. I really dont want replacement though cuz, based on other customer reviews, this particular store takes at least 1 month to replace RMA'ed items. Hope it doesnt go that direction.
