Just a heads up I'm brand new to messing with memory timings so thanks in advance. Mobo: asus m4a79t delux Cpu: amd phenom II x2 550 Memory: corsair cmx4gx3m2a1600c9 When first installed it read at 1333. I've changed it in bios to run at 1600. Next though I ran cpuz to check timings: Cl: 11 T TRCD: 11 TRP: 11 TRAS: 29 TRC: 41 Cr: 1T Dram frequency: 802.7 Fsb: dram: 1:4 Nb frequency: 2006.7 Has anyone gotten this memory to run with better numbers on this board? What values can I change in bios safely with modest cooling? Let me know if you need more info. Thanks again.
