Moving over to the dark side

Been an AMD man for ages now. my last intel was the celeron with i overclocked to 400Mhz. I was thinking about moving to Gigabyte GA_965P_DS4 with E6600 and GeIL 2GB PC6400 800MHz. the E6600 has an FSB of 1066MHz, so i am not sure the memory will be up to the task if i start to overclock. if so, can anyone recommend any other type of memory? the whole lot is about £600. would you say that's a lot of bang for your buck?

cheers

FSB on Intel is quad pumped - i.e. only 266Mhz FSB x 4 = 1066Mhz.

RAM is double pumped i.e. PC6400 is 400Mhz DDR'ed to 800mhz. Thus PC6400 RAM is actually much faster than the stock BUS speed of 266mhz allowing for a good overclock.

PC4200 is stock RAM (i.e. the minimum for 1:1). Anything above this has room for clocking

. Generally, you won't really need more than PC6400 - a good set of this stuff will easily get you a good clock. The G.Skill HZ is good because it can clock to 500Mhz+ usually (make sure you get the right batch with the Micron D9 chips which clock very well).

I would get the GEIL 6400 stuff,

The geil seems to be more compatible with the gigabyte mobo's.

The D9 micron g skill hZ has issues with the DS3 getting over 450 FSB

Yeah - I only used it as an example. I have the TeamGroup Team Xtreem D9's (PC5300 3-3-3-8).

Just to clarify smids post on one point.

The reason why DDR2-PC4200 (533DDR or 266mhz) is a match for the Core2@stock ( 1066Quad or 266mhz), is because the processor bus is 64bits wide, while the memory bus is dual channel, and therefore 128bits wide.

So the memory clock should be half that of the processor if your looking at the quad/ddr speeds, or the same as the processor if your looking at the true clock speeds.

So if you want to overclock your processor, perhaps you would increase the FSB to 400, then you'll want memory that does 400 as well, which would be PC6400.
