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.


Thanks

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 ddr2 memory DRAM frequency is 266 mhz this means that i have 532mhz memory right?

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!

mmm... I ve got DDR3 and my command rate is 1T,DRAM Frequency is 798Mhz, hannel band is dual and total size is 6GB (not sure it is one or 2 sticks) so I think the x in DDRx has nothing to do with it, its the CR that seems to matter

I quote "As "nate42nd" already said "depending if you're running dual channel or triple channel, CPUZ will cut it in half or thirds respectively. It should tell you what you need to know."
Therefore, just to clarify for everybody... To know a what speed your memory is running at you need to download CPU-Z, go to the "Memory tab" and look at the memory speed. THEN, you will have to multiply by 2 or 3 if your RAM is either dual or triple channel. DDR2 doesn't mean dual channel and DDR3 doesn't mean triple channel."

dual channel at 798MHz = 1600Mhz ? it d be nice to know for good
