The most common RAM around right now for system memory is PC-133 CAS 3 ram, because it is so cheap. PC 133 CAS 2 ram is also very common, but it costs a little more because there can be as much as a 30% increase in memory bandwidth. Now if you are willing to spend a little more money on RAM, there are even better alternatives. PC-150 RAM is becoming more common especially for overclockers who want to be able to overclock by running the bus at higher speeds which is only possible if you ram can handle the bus speed. The Overclockerz Zone has recently released the PC 170 RAM, which was previously unheard of for system memory. The RAM is guaranteed to run at speeds of at least 170MHz at 2-3-2.
To be honest, I was a little confused about CAS 2 and CAS 3 RAM when I started this review. So I did a bit of research so I wouldn't just be talking out of my ass. I knew their were three different timing for ram, CAS 2 is 2-2-2, and CAS 3 is 3-3-3, but 2-3-2 is also common, and I supposed there could be other combinations. The first number is the CAS Latency, the second number is the RAS to CAS Delay, and the third number is the RAS Precharge Time. This still probably doesn't mean to much to you so let me clarify a little further. CAS Latency is the latency between the read command and time the data becomes available. RAS Precharge Time is the amount of clocks after a precharge command has been issued. Finally, the RAS to CAS Delay is the latency between the active command and the read/write command. You may still not fully understand what these things mean, but you should have a general idea. Basically each one of these numbers represents some kind of a delay, so the lower the number is the better.
