Be prepared for perhaps the shortest motherboard review you have seen yet on Amdmb.com! :) While we reviewed the KR7A-RAID motherboard back at the end of January, Abit has released an updated version of the board, called the KR7A-133R.

There are basically two changes made two this model and one is a specification. First, Abit has upgraded the south bridge on the KT266A chipset to increase the ATA stats to UDMA 133 on the standard and RAID IDE channels. This increase in hard drive performance will be fairly small, even if you are using one of the Maxtor hard drives that uses the technology.

The other change is merely some performance tweaking by Abit’s engineers on the KT266A chipset, which gave me a modest boost in performance.

Because the board is physically identical to the Abit KR7A-RAID board, if you would like to skip right through to the benchmarks, click here. Otherwise, I have copied exactly the second page of this article from my previous KR7A review.
