Double-sided DDR400 on S754 A64

I'm looking into building an Athlon 64 system, probably around the 2800+
or 3000+. I've read on Tom's Hardware
(http://www20.tomshardware.com/motherboard/20040602/) that socket-754
Athlon 64s do not (officially at least) support two double-sided DIMMs
at DDR400 speeds. I already have a pair of 512MB Corsair PC3200 DIMMs
on the way (don't know yet whether they're double-sided). I haven't
ordered a motherboard yet, but I was looking into the MSI K8N NEO FSR--I
downloaded its manual and found that it purports to support two
double-sided DIMMs at DDR400 speeds, despite the specification.

So my question is, does anyone here have experience in using (or not
being able to use) two double-sided DDR400 DIMMS in a Socket 754 system?

I've two double sided DDR400 DIMM on ly Asus K8V SE Deluxe
each DIMM is 512 MB
The total is 1 Gb on the computer

I believe this is an officially supported configuration

I too have an Asus K8V SE Deluxe with two double-sided DIMMs installed.and
running at DDR 400. Trust the motherboard manufacturer's manual -- the 754
A64s are most certainly capable of this configuration, but perhaps there are
some motherboards that can't handle it. The MSI board you're looking at
should be fine.

I know it may be a bit unusual, but I think Tom's Hardware may have a
typographical error. The chart in the book for my MSI K8T Neo-FSR (skt
754) shows the system will run at 400MHz 2 double sided DIMMs for most
configurations. Running 3 double sided, or 2 single sided and 1 double
sided, or 1 single sided and 2 double sided, all cause the system to
drop down to 333MHz. This concurs with information I have read in other
sources.

I am running 2 double sided 512MB DIMMS and they are running at 400MHz.

Download the manual for the board and look at the section about Ram,
just about all of them have a chart in the manual of what's supported
and at what speeds, take you 5 mins. ;p

I did that, as I mentioned in the OP...

btw, I have two double sided 512MB sticks in my VNF3-250 and run them at
DDR400+ speed no problem.

That's what I wanted to know. Since I read conflicting reports about
whether it's supported, I wanted to find out if it works in the real world.

Thanks all who replied.

I have a Epox 8KDA3+ and it only supports 1 ds dimm I know I have one and
with 2 ds dimms got BSOD until I removed one dimm. I am looking for SS dimms
1Gb size that will work, any ideas?

C O R R E C T I O N: It will only run at 400 MHZ with single sided
DIMMs. Either one, two, or three. But ALL must be single sided.

I tried to send an attached .PDF before, but it may not make it. So,
here is the link: http://www.epox.com/USA/article.asp?ID=1684

It's an update to your manual addressing memory.

You're right about not working with two double sided DIMMs.

So my question is, does anyone here have experience in using (or not
being able to use) two double-sided DDR400 DIMMS in a Socket 754 system?

Replying to myself...

I bought an Athlon 64 3000+ (Newcastle), ASUS K8N-E Deluxe, and 2x 512MB
Corsair Value Select PC3200 CL2.5 DIMMs. 400MHz CL2.5 timings were
detected and set automatically. No stability problems (so far; I just
finished installing Windows this morning; Prime95 has been running for
over an hour without issue).

I've been unable to find Tom's source, but the limitation doesn't seem
to apply (to all boards, at least).
