[QUOTE=dazzab80;2003569]If your board is the K9NGM-L then it supports PC6400, PC5300 and PC4200 (according to crucial)[/QUOTE]
No, it’s just the K9NGM.
I’ve used both the Crucial & Kingston memory calculators, and they tell me what’s compatible, which is fine, but I was trying to find out which will perform better.
As I understand it (which could be wrong of course) DDR 533, 667 & 800 are all bandwidth speeds, but your system bus speed has an impact at what each of these actually runs at when they’re installed.
I’ve read bits here and there on various websites and from what I can grasp, as well your processor having a multiplier your memory does also, and depending on how the system bus speed divides into the memory speed, this determines if the memory module will run at full speed or not.
Can anyone tell me if this is correct or not ??
I guess basically what I want to know is, is it possible to buy a DDR 667 memory module and depending on the bus speed of the PC that the DDR 667 module could in fact be slower than a DDR 533 module ? because I don’t want to buy DDR 667 or DDR 800 and install it to find out that it’s actually slower than DDR 533.
