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.
