Yes, that should work fine. 4x1 GiB of PC3200 is the maximum memory that can be installed on that motherboard.Mark68 wrote:Can I add another 2GB (2x1GB) of Kingston DDR PC3200 (KVR400X64C3AK2/2G) RAM in the second and fourth physical slots?

If you run a 32 bit version of xp or win 7 you will not be able to utilize all 4 gb of memory only a little over 3 gb. You need a 64 bit windows os to use all 4 gb, also I would make sure whatever memory you buy can run at the same timings as your current memory just to be safe I am a bit rusty on old 939 pin boards specially considering I owned a 940 pin fx-53 on a asus sk8n.....a friend of mine is using a dfi board with a fx 55 still I can ask him how much memory he is using.

"DRAM Configuration: CPC: Disable" = 2T command rate. I understand you are not overclocking. It is a factor of the A64 not being able to handle 4 sticks of memory at 1T command rate; remember, the memory controller is on the CPU.
vargis14 wrote:Absolutely drop the command rate to 2T as everyone else said.
As for overclocking My friend has the same board with a fx57...not the fx55 like i thought but that motherboard is a great overclocking board....DFI was the boards to get back in the day.
I know that chip runs at 2.2ghz you should be able to get 2.6 easy sometimes 2.8 with that motherboard .....do not be afraid they don't run that hot overclocked and there are plenty of guides and youtube videos showing you how to do it. Just follow instructions
Since you are trying to get the most out of that old system. Here is one example of overclocking to 2.7ghz

And no you do not have to lap your heatsink

It uses a multiplier of 11 with 200 bus/ht speed. I have read that motherboard hitting 300 base clock... But you would be better off trying for 250 x 10.5 or 11 2625mhz or 2750mhz. Those are just a tiny amount of examples of the multiplier combinations that board is capable of.

A extra 400-500mhz can improve performance in games a lot specifically if your cpu is bottlenecking your gpu.
