Configuring memory the right way

[Polarisz]

Hi
Currently my pc has got 4gb of ddr3 1333Mhz ram memory (Kingston). I don't game or video edit on this pc but since I tend to multitask a lot, my current ram usage is about 3,63gb on average. I'm figuring that upgrading to 8gb will make things faster. Am I right on this?

My motherboard (H61M-P21 B3) only supports up to 1333Mhz (with Sandy Bridge cpu).

Looking at memory in CPU-Z, it says my DRAM Frequency is 665.1Mhz. Is this the right setting (i'm thinking 1333/2)? Can I tweak this in the bios to oc the memory a bit? At what speed should I set DRAM frequency

Yes buying more ram will make the computer much faster since you are using all the current ram.

667mhz is correct you have 2 rams each running at 667mhz times that by 2 and u get 1333mhz (not 1333mhz times by 2)

The number of sticks has nothing to do with the freq or data rate. 2x2GB 1333 runs at the 1333 data rate same as a 1x4GB 1333 runs at 1333. 1333 DRAM has a true frequency of 667 and this is DDR (DOUBLE data rate) so you take true freq x 2 = effective data rate or here - 1333. Your best would be to get 2x4GB of 1333. Just wanted to explain so you wouldn't take the bad info and expect to see them running at 2666 😉

My other pc has 1600Mhz memory but also shows a frequency of ~667 Mhz. Shouldn't this be 800?
Oh, and another question: can I put 1600Mhz ram on a mobo that only supports up to 1333Mhz? Will it just run slower or will it not work at all?
