What are those Clock-timings all about?

I appreciate that 2-2-2-5 is better than 3-4-4-8, but can anyone explain why?! What do these numbers represent? And what's CAS as well?<BR><BR>Cheers,<BR>ShiftyGeezer

ShiftyGeezer that's a very difficult question to answer as it'll take a long time.<BR><BR>Think about it this way, the higher the latency the longer your system has to wait for data. For instance with memory that can run CAS2 instead of CAS2.5 or CAS3 your system only has to wait two clock cycles instead of 2.5 or 3, that might not sound like a lot but when you factor in your system does millions/billions of calculations in a second, it can make a huge difference.

So memory isn't synched with the CPU clock? Is there no way to get a 333MHz FSB to access 333MHz memory on a per-cycle basis? I'd have thought this the driving optimisation for CPU/memory manufacturers. It was certainly possible in the good old days with 28MHz systems <img src="i/expressions/face-icon-small-happy.gif" border="0"><BR><BR>ShiftyGeezer
