I recently purchased some OCZ PC3200 EL Dual Channel Memory (2x512MB) for my
Asus A7n8X Deluxe. WOrks great.
I am thinking of upgrading to the K8V motherboard, and I keep reading that
these new Amd64 boards required buffered or registered memory or something.
Will my OCZ PC3200 El memory work on, say, the K8V?

You should be OK. But, download the manual and see the table of
restrictions on speed versus banks of memory, as the processor
drives the memory directly and isn't very good at it. Latency
improves by having the processor drive the memory, but means more
pins on the processor package and more electrical noise for
the processor design to deal with. Your two memory sticks go in
slot 1 and slot 3 (all on the same single channel of memory).

The FX-51/53 uses registered memory, at least on the SK8V.
THe FX series is dual channel, and that is why there are more pins
and more expense than the AMD64.

The K8V is good for 1GB of memory today, and perhaps 2GB if you
can afford the proper type of 1GB unbuffered modules. The only way
to get 3GB would be to drop the bus speed. The SK8V can handle a
lot more memory, with 8GB max internally, rather than being limited
by available registered memory technology.

Very informative Paul. I thought the whole reason behind 64 bit processors
was that they increased maximum allowable memory? Sounds like alot of
glitches right now.

That is one advantage... 32bit gives 4GBs of addressable space, but you have
to remember that installed RAM and address space are two different things...
often you'll find that the space above 3GBs (on an x86 32bit system) is not
available for RAM.

Socket 939 is for Dual Channel (128bit) memory without the requirement for
registered memory - this means that you can use the FX with your existing
RAM. For now, your best bet is to go with a socket 754 and use your current
RAM.

Good to know. But like people mentioned, on some of these 64bit systems, you
will be hard pressed to be able to install more than 1GB ram. Seems
bass-ackwards.
