I have Dual channel DDR 3200 ram, 2 gigs of it. (512x2) (512x2)

They both are supposed to be clocked at 2.5-3-3-7 per factory settings.
My problem is.. the ram isn't running at 200mhz frequency.

with CPU-Z this is what it tells me:

Freq: 160.7 mhz
FSBRAM: CPU/15
CAS# Latency 2.5
Ras to Cas Delay: 3
Ras Precharge: 3
Cycle Time: 6
Bank Cycle Time: 10 clocks
DRAM Idle Timer: 16 clocks.


is everything running fine? I don't understand why the frequency has been lowered, and is the timings correct? Thanks.. hope somebody can help me.
 
Well, I just accessed my BIOS.. there was three options:

AUTO (which it was on)
MANUAL
SPD

I picked SPD, and it showed all my clocks, the default was DDR400.. so i restarted my computer and !! it worked! My cpuz reads like this:

Freq: 200.9MHz
FSBRAM: CPU/12
CAS# Latency 2.5
Ras to Cas Delay: 3
Ras Precharge: 3
Cycle Time: 7
Bank Cycle Time: 12 clocks
DRAM Idle Timer: 16 clocks.

The only things that changed was the frequency (of course), FSBRAM changed from CPU/15 to CPU/12 .. I dunno, does that matter? and.. Bank Cycle Time changed from 10 to 12 clocks..

does those things matter?
 
well, by changing the memory ratio from cpu/15 to cpu/12, the ram sped up. try dividing the cpu speed by 15 and 12 and notice the numbers you get ;)
the trc is normal

glad you got it working :D
