Default Ram Speed on CPUZ... Help..

Hi guys,

On CPUZ it says my memory is running 255MHZ (1:1) does that mean its running 510Mhz??

Sorry for noob question, I just want to make sure..

Yes, click on the memery tab it should show the speed as 510.

yes, 255MHz = DDR2-510...but DDR2-510 != 510MHz.

there is a difference between DDR speeds and MHz. DDR2-510 for instance is just a made up number by marketing departments to make memory seem faster. 255MHz is the actual frequency of the memory, it is just "effectively" running at DDR2-510 because it moves data twice per clock cycle. manufacturers now like to use the terms DDR3-2000MHz or DDR2-1066MHz when the reality is that those terms are oxymorons...they are impossible.

many forum users like to call DDR2-800 as 800MHz or DDR2-1066 as 1066MHz when they really are just 400MHz and 533MHz. so long story short, yes your memory is running at DDR2-510 and 255MHz, because they are one in the same.

that makes sense if the memory ratio was set to 1:2 because it would then make your memory run at twice the HTT of 255. so your memory would have been running 510MHz which is equal to DDR2-1020. in the screen shot above, it is running at 1:1 with the HTT which is 255, that is why it is running at 255MHz.
