Alright, I decided upon myself this weekend to understand those "strange" numbers that represent the latency of DDR memory in an effort to make an intelligent choice for my next set of dual channel 1Gb memory modules.
From what I have learned, CAS Latency is normally the most important value (representing the number of clock cycles of its operation) with the other values (RAS to CAS, RAS Precharge, Active to Precharge, Command rate) having not as much an impact.
What I dont understand is why some memory rated at a higher latency, is actually more expensive? For example:
I am looking into the Corsair brand of memory and in particular these two:
Corsair TWINX Dual Channel
Corsair TWINX Platinum Dual Channel
The Platinum version of this particular brand of memory actually costs $27.00 US more than its non-platinum counterpart, why is that? Is it just a sale on the more inexpensive one or is there more to determining the "fastness" and quality of memory other than through the CAS value? (Other than Led's and special heatsinks)
If these Corsair memories arent that great, could you guys please recommend a good quality pair of dual channel DDR memory modules for around $200 US (thats my budget).
