Does anyone make Single Bank 1G or 512M DDR3200

[General Schvantzkoph]

Does anyone make single bank 512M or 1G DDR 3200 DIMMs? I've been looking
at the Crucial, Kingston and Mushkin websites and I haven't been able to
find single bank DIMMs that are larger then 256M. On the MSI K8N
motherboards you can't run faster then 333MHz with 4 double sided DIMMs.

German company "MDT" ( www.mdt.de/eng/ ) makes single bank 512MB PC3200
DIMMs. I've bought these by myself and I am very pleased with them.
I don't know about the availability outside of Germany, though.

You won't notice a difference in real life, probably.

I think he wants larger single sided dimms so he can change the fsb from 333
to 400(or higher?) ..
I think it would make a difference

Your right, I want to run this system at 400MHz. I've benchmarked
NCverilog and it makes a 5% difference. You can't put 4 double sided
DIMMs in an AMD64 system and run it faster then 333MHz. I tried it and the
system won't boot, I get a kernel panic if I set the DDR clock to 200MHz.

BTW Memtest86 is worthless, it sets the clock speed back to 167MHz on it's
own. Yesterday I set the DDR Clock to 200MHz, and set CAS to 3 and then I
ran Memtest86 all day. It ran without errors so I figured things were OK.
I exited out of Memtest86 and booted the system, everything seemed fine,
and then I ran my benchmark and got the 167MHz numbers. I then rebooted
the system and the kernel paniced. I rebooted again and ran Memtest86 for
a couple of seconds and then exited and booted Linux, and once again
everything was fine but the benchmark numbers matched the 167MHz rate. I
then rebooted and got a kernel panic. Tried a few times, if I booted from
the BIOS at 200MHz DDR I'd get a kernel panic, if I did it from Memtest86
the system would boot fine so it's clear that Memtest86 is changing the
DDR clock speed. Memtest86 3.2 (the latest) doesn't recognize the Nforce4
chip set so it may be operating in a conservative mode.

Like I said, I don't think you'd notice it in real life. Maybe ...
Except you'd have to know it could be faster if only ... not so fun.

I can on my Gigabyte K8NS-939 with Kingmax Super Ram, Winchester, but when I
updated the BIOS it did a bit like yours and crashed on boot when set to
200, so I went back to the old ones. Although I do actually have the memory
set to 166 since the clock is at 240; the memory is thus at 200. They say
the new Venice is better at 4 DIMMS at 200.

This system is an Athlon 64 X2 which has the latest memory controller.
However it's really a matter of bus loading rather than the controller so
it's not surprising that there is still a problem using double sided DIMMs
at 200MHz. It doesn't really cost me anything to swap out a couple of
double sided DIMMs in favor of set of set of single sided DIMMs on this
system because I'll just use the double sided DIMMs in another less
performance critical system. You are also right about 5% not mattering,
but it's the principal of the thing.

True, there's much to the impression one's pc gives one's self every day.
It's so much fun to boot mine up knowing it's a 90nm running 4 sticks at 200
and running at 26C !!! It only pulls 114 watts when idling, with 2 HDs,
6600GT, sound card and tv card.
