brewskee Posted March 10, 2005 Share Posted March 10, 2005 Hello All, I am new to this type of thing and was hoping you guys could help me out! I need some help regarding my A8N-SLI Deluxe and my Corsair memory. I have 2gigs installed but the bios only sees 1 gig, and it sees it as ddr333 instead of ddr400. The pc is used for gaming and some graphics. Any help is much appreciated! My specs from Sandra - Mainboard Manufacturer ASUSTeK Computer INC.

Corsair Employee RAM GUY Posted March 10, 2005 Corsair Employee Share Posted March 10, 2005 I am sorry but you cannot mix memory with this platform, and all of the modules would need to be the exact same part# and revision. In addition, if you install more than 2 modules the memory controller in the CPU will revert to DDR333 by default. Link to comment Share on other sites More sharing options...
brewskee Posted March 10, 2005 Author Share Posted March 10, 2005 Thanks for the answer. So to achieve 2 gigs, I need to either purchase 2 more 512's with the same part# and rev# and run it at 333, or purchase 2 new matched 1 gigs? What would you recommend for this platform to acheive the best performance? Cost is not a factor! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 10, 2005 Corsair Employee Share Posted March 10, 2005 Yes thats correct. I would suggest Twinx2048-3200C2. Link to comment Share on other sites More sharing options...
