Instability! Can't get past it.
I used some of the advice I got from you guys last evening and I was able to push the FSB up a bit. Right now I'm sitting @ 3664Mhz (458 x 8). The thing is, it's still not 24hr Prime95 stable - what's happening is that at least 1 core gives me "worker thread stopped" while the others continue without failing. One of the 4 cores always gives me (and they rotate) "worker thread stopped".

Also, I attempted a video encode and early on got the BSOD (which is a first for me during an overclock attempt) and I'm assuming that's from a failed overclock.

This is where my settings are at right now:
(I've bold the ones I upped/changed last evening)

CPU Ratio Setting: 8.0
FSB Strap to North Bridge: AUTO
FSB Frequency: 458
PCI-E Frequency: 101
DRAM Frequency: DDR2-917 (1:1)

CAS# Latency: 5
DRAM RAS# to CAS# Delay: 5
DRAM RAS# Precharge: 5
DRAM RAS# Activate to Precharge: 18
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time: 55
Write Recovery Time: AUTO
Read to Precharge Time: AUTO

DRAM Static Read Control: DISABLED
DRAM Read Training: AUTO
MEM. OC Charger: AUTO
AI Clock Twister: AUTO
AI Transaction Booster: AUTO

CPU Voltage: 1.3875v
CPU GTL Voltage Reference (0/2): AUTO
CPU GTL Voltage Reference (1/3): AUTO
CPU PLL Voltage: 1.58v
FSB Termination Voltage: 1.34v
DRAM Voltage: 1.96v
NB Voltage: 1.30v
NB GTL Reference: AUTO
SBridge Voltage: AUTO
PCIE SATA Voltage: AUTO

Load Line Calibration: DISABLED
CPU Clock Skew : AUTO
NB Clock Skew : AUTO

Right now all I'm looking for is 24hr Prime stable @ 458 - 460 FSB .. nothing more then that! But I'm just wondering if there's any more room up there, any more settings up there I can fiddle with that can help me.

Any advice?

Thanks guys!!
