Amd64

Is it true that the A64 only takes up to pc3200 ram?

im using pc3500 dont see a problem

[myth]

3700 for me, still no problems... But in order to utalize its full potential you need to up the buss... (FSB) Or what ever AMD calls it!

[nvening]

I mean if i put some ram which had a higher clock speen than pc3200, would there be no speed increase from pc3200?

Ofcourse no speed increasing. otherwise, you can overclock.

I have a friend using a 4000+ with PC400

I've just ordered an FX55 with DDR400

PC3200 (DDR400) is the recommended RAM for AMD64 iirc. This is because it runs 1:1 with the HTT (somewhat of an equivilant to FSB on older chips). Higher speed memery is recommended/required depending on how much higher you want to put the HTT other than stock.

Thats how I see it anyway, feel free to correct me if wrong!

the best Ram for AMD64 until now is G.Skill but hardly to find in UK. Second choice: OCZ-VX or PQI 3200, A-Data(4400-4800),Corsair XLPT.

All AMD64 systems can use higher than PC3200 but the memory will only run 400MHz unless you overclock the FSB. A64s don't have a divider like a P4 or Athlon XP, but a multiplier. It is referrenced in the BIOS as either 400MHz (2:1 or 2x 200), 333MHz (5:3 or 1.66 x 200), 266MHz (4:3 or 1.33 x 200), etc...and there is NO penalty for using these multipliers like there is on 32 bit only systems because it is impossible to run the memory sync'd with the true speed of the A64's memory buss so it's always async.

The reason I recommend PC3200 is it is usually a better value because the average consumer assumes the higher number means better performance. This is totally false. If you use high quality PC3200 it will run faster than low quality PC4400 and usually with tighter timings.

mmmmmm ill stay with pc3200 im discusing it more in another thread "Ram"
