OCZ 8500 Low-Voltage Blade

[Ket]

Maybe a Fellow P5Q series user has figured this one out. I can boot up to over 500FSB with my CPU and board, so want to settle on 481FSB 24/7. Heres the weird thing, all my voltages and settings are good but my PC9200 errors all over the shop in HCI memtest. Theres nothing wrong with the memory, I've tried it @ 1162 with a lower FSB and most other settings the same as below and its fine.

Settings:

FSB: 481
FSB strap: 333
memory: 1156
Timings: 5-5-5-18
DRAM read control: disabled
DRAM read training: disabled
mem oc charger: enabled
Transaction booster: manual
PL: 8
Vcore: 1.38v
Vmem: 1.84v
GTL: .61
PLL: 1.52v
NB: 1.3v
SB: 1.2v
FSB Term: 1.3v
LLC: enabled
CPU/PCIE spread spectrum: disabled

I've tried numerous clock skew settings, .63 GTL ref and different FSB termination voltages but nothing seems to work any ideas?
