Having a quick browse of the Forum, I've seen people talking about CL values for RAM.
Just out of interest, is there a way to check the current type of RAM in a computer?
I'm going to get myself a new 512 stick, but now that I've seen that CL is a factor, I don't want to buy the wrong type.
Also, are CL values compatible? For example, if my current RAM is CL3, can I get a CL2 and take advantage if it's abilities? Is it worth having different CL type RAM?
Thanks for any help on this.

Thanks to everyone for your help up to now.
Just out of curiosity, does branding hold much weight in the RAM area?
I've been looking at the Crucial, SR, and Misco web sites. SR doesn't seem to state the branding, so should I be cautious? Misco sell a brand known as Corsair, are they a reliable brand? I'm also under the impresion that Crucial make their own RAM, is that accurate?
Also, it seems that my RAM speed type is PC2700, would PC3200 work at a reduced speed (equal to PC2700) as SR are selling the faster RAM cheaper.
Thanks again.

No way... the Intel chipset is also highly inefficient compared to the likes of VIA - still, I get a respectable figure that hovers around 7 GB/s

Do you actually ever hit 8GB/s though?
In practical terms I don't think I've ever seen a benchmark actually hit the theoretical 6.4GB/s of dual channel PC3200.

DDR500 running at 252 Mhz here=PC4032 which means a throuhput of +4GB per sec in dual channel mode = throuhput of +8GB per sec... mwah hah hah hah, you should see UT2004 singing as it is very bandwidth sensitive
Although the tradeoff is a CL value of 3 but at these speeds it hardly matters.

Yep, that's it.

DDR stands for double data rate.
Data can be transferred on the rise and fall of a clock cycle (I think that's how it works) so it's effectively twice the stated frequency. 133 = 266, 166 = 333 and 200 = 400 and so on.
DIMM stands for Dual Inline Memory Modules. DDR-SDRAM is DIMM.

All RAM will run at the spec of the slowest stick.
The difference in CAS Latency won't suddenly give you a major frame rate increase but because of the lower timings the games/apps run smoother and particular in high end games you will lose a lot of the offline lag you sometimes get when loading textures to the RAM - obviously because of the lower timings.
RAM is important, I bought the best which cost a hell of a lot more but from past builds with different rigs using different CAS Latencys going for the tightest timings is worth the extra dosh, especially if you are a picky f**ker like me who notices the difference between 68 and 69 FPS :D

That little app seems pretty good, thanks Nimco.
Having a look at the results, can I assume that the value CAS# Latency under the Memory tab is the CL value I asked about previously? The value is 2.5 clocks, so does this mean it is CL2.5, or have I miss-understood?
Also, again looking at the results under the SPD tab, the Max bandwidth value reads PC2700 (166MHz), but looking in the Special Reserve magazine RAM page, it says that PC2700 is 333MHz under DDR DIMM RAM. Is DDR DIMM and DDR-SDRAM (my current type apparently) two different types?
Thanks.

Yup.

Yup.
Thanks for the tips.
Can I just ask also, does the same hold true for the speed, in that if I were to get a 400MHz (PC3200) stick but find my existing RAM is only 333MHz (PC2700), will the new RAM work at the lower speed, or just not work at all?
Nimco, is this the software you mean [URL]http://www.cpuid.org/cpuz.php[/URL]?
Thanks all.

If you have CL3 and buy CL2, the motherboard will just run at CL3.
