PHENOM II 940 ram timings for 1066?

Buffalo Firestix FSX1066D2C-K4G 4GB 2X2GB PC2-8500 DDR2-1066 240PIN DIMM Dual Channel Memory Kit
Western Digital Caviar Black 640GB 7200RPM

Gigabyte MA790GP-UD4H AMD790GX ATX AM2+/AM3 Sideport CrossFireX Motherboard
Corsair TX650W 650W Power Supply
AMD Phenom II X4 940 Black Edition Quad Core Processor AM2+ 3.0GHZ 8MB Cache

Cpu is not overclocked everything stock. How should I set my dram settings? It is at 2.1volts. currently i've set the 5-5-5-15 and 2T.


DDR2 1066 Unganged Mode, 64-bit not sure if this is correct for dual channel?




memtest shows cas 3-5-1 DDR-1 128 is that right ?

and here gigabyte easy tune says PC2-6400(400mhz) i guess because of JEDEC standard?



Is my DRAM configuration correct for write recovery time, precharge time, row cycle time, ras to ras delay?

Is it stable? You can always email the Buffalo techs for info about some of the more obscure ram timing settings. If you set the timings to "auto" it will probably work fine at stock speeds. Auto timings usually are correct but auto voltages often are not. Voltages set by auto on a lot of the mobos are too low.

Yes you can have them at 5-5-5-15-31, but i prefer 5-5-5-15-24 for a light to no OC. If I ever use 1066 for a big OC then I will jump up to 6-7-7-27-32. It tends to help a lot with stability. If you do ever OC the CPU on a AM2+ system, its sometimes best to jump down to 1:2 ratio and crank up the FSB to 250 so that you have a 1000 Ram.

As long as you're stable. Many 2x2GB kits need 50+ on tRFC
