Athlon64 supports max PC3200 DDR?

[joshc]

I read on the AMD website that the Athlon 64 memory controller only supports a max of PC3200 RAM. This kind of confused me because I thought I read some threads on the forums with people talking about buying DDR550 or something for athlon 64s....am I missing something here?

thanks.

no, it can support anything higher. pc3200 is the stock mem speed that is the standard for today. anything higher then pc3200 is a waste unless you are ocing. same goes for intel.

Nothing above PC3200 is an official spec; PC4000 and such is overclocking memory, basically PC3200 guaranteed to run at those speeds (CL2 PC3200 usually uses the same chips, though).

Regardless, you really don't *need* more than that to overclock an A64.

Cool, thanks for clearing that up...I was just curious cause I just read the AT article on how memory works so doing my calculations PC3200 is only a 200MHZ memory clock which is far slower than what the hypertransport bus runs at.

The core Hypertransport frequency is 200MHz... the bus has its own multiplier, like the CPU.
