Best RAM for K8V Deluxe???

[Carl]

What is the best Corsair XMS RAM for the Asus K8V Deluxe MB w/AMD 64 3200+.
Will PC-4000 work? Black or Platimum Heat Spreader?

Thanks.

You'll notice on the next page of the review, they switched to a
PC3200 2-3-2-6 memory. I would think a low latency memory would be
a better choice than a high clock memory. The processor drives the
memory directly on the Athlon64, so the Northbridge is no longer the
limit to performance. For you to make use of PC4000 memory effectively,
you'd have to wait for AMD to figure out how to make a DDR500 bus on
the processor.

Since the K8V uses the single channel (socket 754) version of processor,
you have limits on speed versus number of sticks. See the downloadable
user manual, for a table of allowed memory bus speed versus DIMM
slot population.

The block diagram for the chipset is here:

To see the impact of CAS latency on Quake framerate, see this

Now, maybe if someone has figured out how to overclock the K8V,
a faster memory would be worth investing in. I couldn't find
much on a few forums I looked at. I wanted to search amdmb.com
forums, but as far as I can tell, you have to be a member to
do that. (There could be an issue with bus locking, for PCI/AGP,
which would potentially limit how far the FSB can be pushed.
At any rate, such an overclock would most likely use one
DIMM only.) Hope you have better luck finding info than I did.

HTH,
Paul

There is a review here, of an Abit board. You can see the numbers
they managed, in terms of clock rates, don't really make use of
PC4000 ram.

Has anyone here tried the OCZ EL PC3200 Dual Channel memory on this board?

PC-4000 will work, but I fail to see the point. I have TwinX1024-3200LL and
it'll do 220MHz 5-2-2-2. I am unsure as to whether the PC-4000 will come
down to CAS2 at those speeds, I would suspect that it does, but I have heard
comments to the contrary.

On the other had, I think I read somewhere that low latency RAM was less
important on the AMD64, but I don't recall the details.

I can follow up on that if you like, let me know.
