VIA KT400 Chipset Overclocking

Motherboards/AMD S462 by jmke @ 2002-12-24

In the search for more performance, I tested 3 brandnew KT400 equipped motherboards, in the hope to outperform my current AMD performance system, based on the KT333 chipset.
Asus A7V8X, Gigabyte GA-7vax and Msi KT4 Ultra are included in this review.

Asus A7V8X

Asus A7V8X:

The Asus motherboard layout leaves alot of room around the CPU socket for a large heatsink/waterblock/phase-changeHEAD.

So far the positive side of the Asus A7V8X..

Can it BE any closer?


This KT400 motherboard also refused to boot with the Hercules R9700Pro and it seems I´m not the only one with this problem. No matter what Hercules R9700Pro revision you have:
- He "almost" got it to work
- AGP 8x bug & ATI fix ?
- Yeah I got R9700 working but what cost, no cdroms and other HD, Sweet
- System POST related issues on AGP 8x motherboards

So again I was forced to use the TNT2 for testing. I was able to get a maximum FSB of 185Mhz. No matter what I tried, no matter what ram was used. Not impressive.

Memory benches @ 166Mhz:

and the maximum stable speed of 185Mhz results in:

Well there is nothing to say really, very disappointing results from the Asus...
Can the Gigabyte save the KT400?
