I had heard this before bios 14, but here is the info.

BIOS release V14 for AB9 QuadGT

Release information:

[ENGLISH]

1. Support FSB1333 CPUs
2. BIOS compiled date: 06/21/2007

I didn't do much testing with 14 because of some reported problem with that bios. Hmm maybe I should since the problem was to do with ICH8R AHCI function & fixed in 15. You would think the 1333 was carried over into the 15 bios, but could have been part of the problem with 14 & removed from 15. hmmm Got me thinking...
