EDIT: I have noticed the other thread that is very similar to mine, but as I have some additional questions, I've decided not to delete mine.
I?m deciding what components to use for my next build. It?s going to be a uATX case, and I?ve decided to go for the Asus P5K-VM HDMI MB, that apparently overclocks very well. It?s the first time I?ve decided to overclock, but I?m absolutely no stranger to the concept, and the recent article about overclocking the 45 nm QX9650 provides a very methodical tutorial.
I?m thinking of using running the memory at DDR2-800 (1:1 divider with FSB at 400 MHz), as faster memory is very expensive unless I choose a 4x1 GB configuration and because it doesn?t really yield better performance because of the FSB being the bottleneck). This leads me to my first question:
Is it still recommended not to use all 4 slots because of wire load etc.? Will the use of 4 slots require loosening the timings other than mandating the use of 2N command rate (is that at all possible ? I recall reading that command rate is locked at 1N because only 4 banks are allowed on intel chip-sets)?
In the mentioned Anandtech article, it is stated that even the worst ?performance? memory will allow a CAS latency of 3. However, when looking at Corsair XMS2 memory, which is labelled as performance memory (with the dominator being labelled as enthusiast memory), it is only specified as being able to handle a CAS of 5.
So should I expect it to handle CAS 3, or do I need to buy more expensive memory?
Would it be advisable to buy 4x1 GB DDR2-1066 memory (still Corsair XMS2 rated at CAS 5) ? providing that utilizing all 4 slots is not a problem ? and then clocking it at 800 MHz while tightening the various timings?
Thanks in advance ? I hope for some great answers
