Then you can setup your CPU GTL's, do some reading in the forums on this, I promise it will help. Also, run OCCT, I find it;s better for overall system stability, and it will only require a 1 hour run. I have now got my system completely 100% stable and rockin. Here is how my bios looks.

AI Overclock tuner: Manual
CPU Ratio Setting: 8.5
FSB Strap to North Bridge: AUTO
FSB Frequency: 533
PCI-E Frequency: 100
DRAM Frequency: 1068
DRAM CLK Skew on Channel A1: 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
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time: Auto
Write Recovery Time: AUTO
Read to Precharge Time: AUTO

2nd Information :

Write to Read Delay (S): AUTO
WRITE to READ Delay (D): AUTO
READ to READ Delay (S): AUTO
READ to READ Delay (D): AUTO
WRITE to WRITE Delay (S): AUTO
WRITE to WRITE Delay (D): AUTO

3rd Information :

WRITE to PRE Delay: AUTO

PRE to PRE Delay: AUTO
ALL PRE to ACT Delay: AUTO
ALL PRE to REF Delay: AUTO
DRAM Static Read Control: AUTO
DRAM Read Training: AUTO
MEM. OC Charger: Enabled
AI Clock Twister: AUTO

Common Performance Level [10]

Pull-In of CHA PH1: DISABLED
Pull-In of CHA PH2: DISABLED
Pull-In of CHA PH3: DISABLED
Pull-In of CHA PH4: DISABLED
Pull-In of CHB PH1: DISABLED
Pull-In of CHB PH2: DISABLED
Pull-In of CHB PH3: DISABLED
Pull-In of CHB PH4: DISABLED

CPU Voltage: 1.4000V Bios / 1.384V Windows
CPU GTL Voltage Reference (0/2): Auto
CPU GTL Voltage Reference (1/3): .620 Lots of reading helped in this area.
CPU PLL Voltage: 1.62 / Higher fsb requires higher PLL.
FSB Termination Voltage: 1.36 / Above 500fsb I found increments of two helped with the erratic reboots.
DRAM Voltage: 1.92 / This used to be 2.11V in previous bios, whereas 2.02V and above was 2.20V, strange.
NB Voltage: 1.40 / 1.36-1.4 I could run above 500FSB but couldn't get past mem checkers until I worked out the NB GTL issues.
NB GTL Reference: .600 / Again lots of reading makes a big difference here.
SBridge Voltage: Auto
PCIE SATA Voltage: Auto

Load Line Calibration: Enabled
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
CPU Clock Skew : Auto
NB Clock Skew : Auto
CPU Margin Enhancement: Performance Level / Still don't know what this does ?????

P.s. has anyone checked the voltages on the latest 1805 bios, my multi meter is on the frits, I need to know if the voltages are what the bios says they are.
I had no luck with these suggestions. With FSB Term Voltage at 1.28 I was only stable for an hour and with 1.3 it froze within minutes. I also tried 0.630 and 0.635 for NB GTL Reference and had no luck. I also tried 0.670 for CPU GTL Reference (1/3) but that was bad, too.

I think I will either try a different BIOS or just push on to 500FSB if there are no more suggestions. I normally wouldn't do the latter without first being stable where I am at but I have tried everything except messing around with the CPU GTL Reference, which, as I'm writing this I think may be a good idea to start doing.
