Great score)))

Socket A FSB record?

This is impressive for a KT600 chipset.

I can't let this question without an answer. So, is this the highest FSB frequency score? Next one I found this:

 

( ivanov`s Reference Frequency score: 284.74 MHz with a NF7 V2.0 ) - Ivanov's 284.74 MHz with Abit NF7 V2.0 ( nForce 2 Ultra 400 ). I OCed a lot of Socket A motherboards. I OCed almost every VIA chipset on socket A (so I have a lot of experience in this matter).

Yes, this is the highest socket 462 FSB score. Here's a link to the results from the hwbot search function: Overclocking, overclocking, and much more! Like overclocking.
