The mobo came with BIOS 0602 and its OC stability was OK until ~460FSB. I didn't spend enough time with the original 0602 due to constantly random DET RAM hang at high +460FSB.
I eventually flashed to the newest Beta BIOS MF1004 using EZ flash and it was capable of going up to ~470-475FSB but it's still unstable for high FSB with the Quad core.
There was memory compatibility and OC stability issues and same DET RAM hang with MF1004 BIOS at high FSB test settings.
As per KUP's recommendation, I downgraded the BIOS to 0505.
Easy way using EZ Flash: Reflash with a current or newer BIOS file and shut the system down while it's in the flashing process.
Rename the MF0505 BIOS file in the root directory of your USB drive to FORMULA.ROM and now turn on the system to get auto BIOS recovery.
It will auto do an erase and search and reflash to the FORMULA.ROM bios file(renamed 0505 in this case). It's completely safe and you'll just need to do a full CMOS clear after.
I'm very impressed by the new revision double sided 2x1GB 1066 Ballistix Tracer kit by the way.
Eventhough some has complained about its compatibility and OC-ability with this mobo but I do find the new rev double sided Ballistix Tracers to have great OC-ability with relatively low given volts.
I also have an older Ballistix Tracers 1066 2GB kit from last year to compare and it's capable of being stable @ DDR2-1165 (5-5-4-9-3-30-3-3-8) from my previous P5K-Deluxe setup.
But, it doesn't scale well with given volt and not stable at 5-4-4-9 primary timings.
Now Look closely at new rev. double sided Ballistix Tracers primary timings and the subtimings to its given VDimm in the template. :up:
I feel that there may be still a small room for further timings tightening but it's more than good enough for now.

The following template is a reference for a 99.9% 24/7 stable configuration on air. Several hours of testing sessions using OCCT 2.0.0.a MIX and Prime95 v25.6 Blend/Small FFT stable.
Most importantly, no cold boot issue and no DET RAM hang with the following specific configuration.:up:
