what is the cl 2 or cl 2.5 or 3, whatever.. (it stands for latency or something) but does it matter much?

What I have to say about memory is this.  If you picky about your performance, then by all means, go for the good shit.  But, usually, it better to just get more ram instead or anything else.

I got this ram from kingston called value ram.. I have 768 megs, and honestly I can't tell the difference between when I had 128 megs and now.  I even have dual channel memory and I can't tell any difference.

You'll notice a difference if you run newer games, like Half-Life 2 or Doom 3. I have 1 gig (512x2) of Kingston HyperX PC-4000, and i can run ANYTHING and my pc wont flinch. If i tried to do that back when i had 256 of ram, my pc would have done a ctrl-k. Desktop applications and games like Tribes, you wont notice. But if you run memory demanding games and programs, you'll notice a TREMENDOUS difference.

well Tribes Vengeance takes forever to load and I can't even play online, that's probably more the video card/lag though, dunno.  nvidia fx 5200.

I've got 1gb of some generic brand ram.  Sh!t rans games great like doom3, unreal, tv, hl2, most games that run dominantly on heavy memory usage.

hmm ill try to make this simple ok  CAS is "Column Addrress Strobe", think of it like a big spreadsheat with memory blocks.  Each block has its own specific address, there is also RAS which im sure you can guess what that is =p

Anyway first off the memory controller chipset will access the memory and request a specific row of block "RAS" as to where it can place its block of information. It then placing an address as to what row the info is... you must then wait a few clock cycles until the column address is then also placed, This is called RAS to CAS delay or CL.

This procedure is not always sucessful, it will sometimes run accross already filed memory locations and have to do the search all over, this is where the CL 2 2.5. 3 comes in to play. Theses numbers stand for nanoseconds and how how fast they can do RAS to CAS delay, the lower the number the better.  If you are not doin anything to memory intensive you wont noticed the difference, But if you are playing games like T:v, HL2, Doom3 you will notice which much better loading.  stability between your system compontent more fluid and in turn allow for better overclocking performance.

I hope you bitches can understand...cause im not even sure if i can really if not  :thebird3:

no way you get 180  + fps with a fx 5200.
I'm lucky when it get 40 to 50

Thats not true easy i seen 140 with a 5200 AGP, but it was a P4 2.4c HT, and DDR memory... Not sure what you are running but i do remember that framerate

bah, then what's my problem..
1.83 ghz (xp 2500+ barton)
768 mb ram (dual channel)
nvidia geforce fx 5200 (and yes vsync is off)

It seems if they can get 140 on those that I should be getting better than 40 to 50.

I run tribes, hudbot, detail cranked, 1600x1200, 4xAA 8xAF, HM at 5000 and get about 180 average.

If I run tribes at 1024, no AA/AF, and stock HM, I push like 600/700 or some ridiculously high number.

Ram timings ... matter in some cases.  It's hard to really explain.  A lot of it is myth, however.  Overclocking your ram only a few mhz makes up for any difference you would get from dropping from 2.5 to 2 ... and most of the new DDR2 ram coming out uses a higher CL anyway.

Your best bet is always to buy good quality, name brand memory that is rated for faster than what you need ... like joker did with the pc-4000.  Depending on your motherboard, you can choose to run the ram concurrently with the FSB, or you can set it run at 3:4, 4:5, or whatever you want.

In short, more is obviously better.  Ram timings will help in synthetic tests, aka sandra ram bench, but it will only make like ~3 percent difference.  In any real world ap, you'd be better off running faster ram.  If you can run fast, stable AND low latency, even better ... but the speed it runs at is generally more of a factor than the latency.
