The difference will show up in benchmarks, but will be small. Going with nForce can also give you more performance.

Check the specifications of the memory, often high speed memory of that era needs extra voltage and manual settings of timings. The default SPD settings will be conservative like 3-3-3-8.

The ram is Corsair VS1GB400C3 and the specs says 3-3-3-8 at 2,5v. Strange thing is that in ubuntu with the decode dimm command it says for one 3-3-3-8 and for the other 3-4-4-8 when they are same model with same chips (even if one is a bit taller than the other like manufactured in another version.

Yea that's standard RAM. You need to look for DDR400 CL2 memory.

Thanks, I'll try to push a bit more speed from this system, actually the fastest I can build with the hardware I got. 😁

Corsair Value Select were popular, they used different type of IC not always the same (the cheapest available)
Lot of them used Samsung UCCC famous to running at 250mhz 3-3-3-8 1T at default voltages... IC DDR1 made by Samsung don't like voltage; I know this because I have 2 kit of these particular Corsair Ram.
Anyway you can push them only with 754 or 939 platform.
With 462 or 478 the best options are winbond BH-5/BH-6 (256*2), UTT are in general more difficult to get stable.

I remember on the nForce2 there was a strange quirk where it was actually slower if the last latency figure was set too low (I don't know what that number represents). So 2-2-2-5 would benchmark slower, I think optimal on that chipset was 2-2-2-11 or something like that. I have some Kingston HyperX which I think is speced for 2-3-2-6 but on my nForce2 I always ran it at 2-3-2-11 for that reason (that's from memory, could be wrong on the details).
I have no idea about VIA, maybe on the KT600 the fastest possible settings would perform as they should, but if you get fast RAM for that board I'd try experimenting with the settings just in case it has any such quirks.
