Where do I check my system RAM speed?

I just got done bench Prime 95 testing a new build on stock settings. I also adjusted the timing in the BIOS to get the factory RAM settings up to the advertised speed.

Where on my PC can I go to confirm that my RAM is running at the proper MHz speed? The system display just shows how much RAM is installed and the speed of the CPU. I'd like to see the RAM speed - so I can confirm my settings are correct.

Thanks

Download and install CPU-Z, here.

I D/L that on 2 computers - and neither of them reads anywhere near the MHz that I would expect. Both have DDR3 1600 RAM -

One I'm at now - and I'm reading in the " MEMORY " tab

Triple Channel Core i7

Size 6144 MB
NB Frequency - 3198 Mhz
DRAM Frequency 799.5 Mhz
CL - 8
tRCD - 8
tRP - 8
tRAS - 21
tRFC - 60
CR - 2T



I'd expect something to be at least the default 1333 - but I'm pretty sure this PC is @ 1600 even though I'm not reading it anywhere at the moment. I'm missing something here. Where should I be reading 1600 MHz - to confirm I'm running at the proper speed.

Do I multiply the CR - 2x DRAM Frequency of 800 to get 1600????

i have ddr 2 2 gb.
it says dram frequency 332.5 mhz.
it means frequency is 666 mhz ?

why we multiply by 2 ?

DDR2 = x2
DDR3 = x3

Modifiers can be fun!
