Asus M4A78 Pro and Corsair RAM

[tmaugham]

My configuration: Asus M4a78 Pro, AMD Athlon X2 64 2700mhz, Corsair cm2x2048-6400c5 (2 2gb sticks), XP Pro 64 SP2

 

My questions:

 

1. This is 800mhz memory but cpu-z says it is 400mhz, why the difference?

2. I had originally set the DRAM frequency to 800mhz but I was getting some BSODs so I reduced the DRAM frequency to 667 mhz but cpu-z reports that the DRAM frequency is only 301.4 mhz, why the difference?

 

Thanks very much...

1. DDR2-800 IS 400 Mhz. That's why it's called DOUBLE Data Rate (DDR).

2. AMD CPUs sometimes have odd divisors, which may be the reaon you see that.
