Can someone explane ram to me? <<<< NOOBIE

post #1 of 6
Thread Starter 
Can someone please simply explain ram to me? im new to overclocking i have a good knowledge of most computer parts and terms just never really explored ram. what does CL9-9-9-24 mean? what do the letters CL mean and what does each digit mean. Lastly what should i look for when buying new ram? Im buying a 2500k or a 2600k soon along with a new mobo. right now im running 1333 ram so i know im going to need to upgrade especially if im overclocking. thumb.gif

Try reading this article:

http://www.hardwaresecrets.com/article/26/

tells you what the numbers are.

As far as the speed in mhz of ram goes, you wanna max it out to what your particular processor (or mobo) can handle (look it up for your model). then find out if you can OC with the multiplier, if not you'll have to OC your ram in order to OC your processor, so if that's the case you'd better check up on whether the ram you're buying is good for OCing ... for instance mine isn't, according to reviews, so i'm just OCing with the multiplier.

Hope that helps.

CL9-9-9-24 is the timings. Tighter the timings, the faster the ram is at accesssing the data that is on the it.

Anyway this is taken out of my wonderful newbie guide on overclocking (see sig)
Quote:
There are 5 main timings in for RAM and they are the following:

tCL (CAS Latency) - 9
tRCD - 9
rRP - 9
rRAS - 24
Command Per Clock (CMD) - 2T

The best way I can describe each of these is to use the examples used in a MaximumPC magazine I got, which describes things as if they were a librarian going for row to row of books in a library >.>

“tRCD setting, for example, describes how much time the librarian has to get to a certain row on a shelving column. Set it too low, and she can't get to the row where your desired book is.
Say she reaches the row, tRAS determines the amount of time the librarian can linger there find your book.. tRP is how much time the librarian has to get from the row she was at to the bottom of the ladder.
TCL is how much time the librarian has to move from one shelf of books to a different one. Setting this too low is like asking her to move a 30-foot ladder 100 yrds in 2 seconds. TRAS is basically how much time overall the operation takes to climb the ladder, get your book and get off. CMD is the amount of time between one request and the next.”

Also see here as well for more info. I call it The Holy Grail of RAM

RAM is kinda like a tunnel. The amount of ram is like the width of the tunnel and the frequency and timings are like the tunnels length. We want our tunnel to be a chode.

CL is Cas Latency, and those numbers are various latencies of the RAM.

Ram speed is completely independent of processor speed on P67, you will not need to upgrade your memory to overclock the pants off that thing. It used to be linked on older processors (core 2 duo), but not on the newer ones.
