Which BIOS is better, 0702 or official 0704?
Can you help me reach 500FSB for 24/7 stability?

So far I got 3 hours of Orthos Blend using these settings:

CPU Ratio Setting: 6.0
FSB Strap to North Bridge: AUTO
FSB Frequency: 500
PCI-E Frequency: 100
DRAM Frequency: DDR2-1002 (1:1)
DRAM CLK Skew on Channel A1: AUTO
DRAM CLK Skew on Channel A2: AUTO
DRAM CLK Skew on Channel B1: AUTO
DRAM CLK Skew on Channel B2: AUTO
DRAM Timing Control: Manual

1st Information :

CAS# Latency: 5
DRAM RAS# to CAS# Delay: 5
DRAM RAS# Precharge: 5
DRAM RAS# Activate to Precharge: 15

CPU Voltage: 1.225v
CPU GTL Voltage Reference (0/2): 0.630
CPU GTL Voltage Reference (1/3): 0.630
CPU PLL Voltage: 1.5v
FSB Termination Voltage: 1.24v
DRAM Voltage: 1.8v
NB Voltage: 1.30v
NB GTL Reference: 0.550
SBridge Voltage: 1.20v
PCIE SATA Voltage: 1.50v

Load Line Calibration: ENABLED
CPU Clock Skew : 400ps
NB Clock Skew : 200ps

EDIT: CPU and RAM ruled out, CPU works even 3.6GHz with 1.225V, RAM 533MHz with 1.8V.
1.30V NB seems to be most stable, 1.28V and 1.32V was max 40min stable.
Now testing 8x500, same settings, which are the most stable for now.
