Differences between RAM

post #1 of 4
Thread Starter 
I have some questions on RAM.

I've read that there isn't much of a difference between DDR2 and DDR3. Not that I have a choice though when I upgrade since DDR3 is the norm. My current computer has Kingston DDR2 2x2 4GB and I don't see a huge difference between my friends computer with DDR3.

What is the difference between 1066, 1333, and 1600 DDR3? Then there is (OC) which I assume is overclock.

Does ram brand even matter? I've built 4 computers for people with
Code:

which seems to be very popular. It's low profile and low voltage and usually the cheapest. What it makes better than another brand? The only reason I can see people getting another brand is for the fancy heat spreaders to match your mobo's color scheme.

I read that with a CPU like the Celeron G530 it can only use 1066 RAM. Does that mean I can only use 1066 sticks, or can I use 1600 but the it won't go past 1066?

What do the timings on ram mean? Such as 11-11-11-28.

Thanks all thumb.gif

Hey mate,

About the G530, it can access the memory only at 1066, not more. This means you can put whatever DDR3 you can find (1600, 2400....) but it would work at 1066. My advice would be to get as fast as possible if the price is similar for one reason: you can lower the stock timings (the 11-11-11-23... to something like 9-9... whatever is stable for your config.
These timings are latency measurements, a measurement of the slowness the memory controller's access to a certain memory cell. The less slow the better, so the lower the number the better. For a more "professional" explanation take a look at this article:

The brand doesn't really matter, except for warranty in case something bad happens, which rarely does, except when OCing the RAM chips which you clearly won't do biggrin.gif That kit should be good.

The different is really the price of it. DDR2 1066 is $65-$75 for 4 gb and DDR3 1600 is $23-$26 for 4gb. The number on the ram is basically cycle pre second, so lower is better.

thanks for responses.

I guess that Samsung ram is the best then. Low voltage, good timings, lifetime warranty, and low profile. No wonder it went out of stock so fast. thumb.gif
