Ouch! When Sandra reports 44mhz PCI bus I believe it

OK Guys. I posted a few weeks ago about this little problem I have. When I run my tbird at 1000(100x10) Sandra reports my PCI Bus at 33mhz which is correct. When I run it at 1000(133x7.5) Sandra reports my PCI bus at 44mhz and my AGP Bus at 88mhz(x4).

When I reported this issue a few forum members stated that it is a known bug with Sandra to report an incorrect PCI bus speed with Kt133A chipsets and 133fsb. I don't think I believe that. I think it really is running at 44mhz.

The reason why is because of my 3 year old Maxtor Diamondmax 2500 Plus UDMA33 drive. I use it as a backup drive (D). Everyone knows the history of those Maxtor drives when it comes to non-traditional PCI bus speeds. I put the drive in my box and cranked it to 133fsb and the machine was a mess. Anytime I tried to access that drive it acts very slow and flaky like they are notorious for. When I try to delete a file from the drive it takes about 2 minutes to delete a measly 50kb jpeg image. So I set it back to 100x10 and everything runs peachy.

So I feel pretty strongly about the fact that either there is a bug in the KT133A chipset or there is a bug in my Turbo-R that incorrectly sets the PCI/FSB ratio to 1:3 instead of 1:4. Unfortunately there is no place in the Turbo-R bios (V1.16) to set the PCI/FSB ratio as far as I can tell.

So to those of you out there that beleive it is actually a bug with Sandra 2001 can you show me some kind of documentation that proves me otherwise?

I hope not... I posted another msg like yours, I am having the same issue. Except im running 146 fsb, and in Sandra, it reports pci at 1/3, and agp at 2/3. This has been the case with every bios available for this board.
