Welcome to Tom's Forum! :) 

If you 'see' CPU-Z showing DRAM Frequency of 400 MHz then your RAM is running at 800 MHz. DDR {Double Data Rate}. CPU-Z shows "I/O bus clock" and not "Data rate".

So where are you seeing 400MHz?

i see the 400mhz on speccy program that's tells me what i have on PC and the speed it is running on aand how munch ram it is useing. some did told me that you can crack the memory to run at full 800mhz then 400mhz.

You don't crack hardware nor do you hack it... You go into BIOS and change settings there. Read settings on CPU-Z. Use that rather than what you're doing.

Use CPU-Z http://www.cpuid.com/softwares/cpu-z.html

Speccy seems to be doing the same thing as CPU-Z, 530*2 = 1060 MHz; the FSB/BCLK speeds fluctuate explaining the slight variations. There's no 'such' a thing as 530 MHz DDR3.


CPU-Z in this example the RAM is running 533*2 = 1066 MHz
