sure wish i had kept the setting wrote down BUt will do that in the future .We will see if I can do it agin ..

anxiously awaiting those settings. I'm still havin' a bear of a time getting this locked down. I used the settings suggested by mikeyakame and I'm not getting anywhere. I'm definitely not blaming mikey. I realize it's a hit or miss type thing and especially challenging when you're not even physically in front of the PC.

I can't even get past DET DRAM with the following settings.

AI Overclock Tuner.......................................   Manual
CPU Ratio Setting.........................................   7.0
FSB Strap to North Bridge..............................   333MHz
FSB Frequency............................................   500MHz
PCI-E Frequency..........................................   100MHz

DRAM Frequency..........................................   DDR2 - 1002MHz
DRAM Command Rate....................................   2N
DRAM CMD Skew on Channel A........................   AUTO
DRAM CMD Skew on Channel B........................   AUTO
DRAM CLK Skew on Channel A.........................   AUTO
DRAM CLK Skew on Channel B.........................   AUTO
DRAM Timing Control.....................................   Manual

READ to WRITE Delay (S/D)...........     9
WRITE to READ Delay (S)..............     4

READ to READ Delay (S)................     4
READ to READ Delay (D)................     7
WRITE to WRITE Delay (S)............     4
WRITE to WRITE Delay (D)............     7
WRITE to PRE Delay.....................    15
READ to PRE Delay.......................     7
PRE to PRE Delay.........................     2
ALL PRE to ACT Delay...................     7
ALL PRE to REF Delay....................     6
DRAM Static Read Control..............................   Disabled
AI Clock Twister..........................................    Moderate
AI Transaction Twister.................................    Manual
Common Performance Level..............10
Pull-Ins.........................................Disabled
CPU Voltage...............................................    1.47500V
CPU PLL Voltage..........................................    1.58V
Northbridge Voltage.....................................    1.63V
DRAM Voltage.............................................    2.10V
FSB Termination Voltage...............................    1.40V
South Bridge Voltage....................................    1.050V
SB 1.50V Voltage.........................................    1.50V
Loadline Calibration......................................     Disabled
CPU GTL Voltage REF...................................     0.63x
NB GTL Voltage REF.....................................     0.63x
DRAM Controller Voltage REF.........................     AUTO
DRAM Channel A Voltage REF........................     AUTO
DRAM Channel B Voltage REF........................     AUTO

CPU Spread Spectrum.................................     Disabled
PCI-E Spread Spectrum...............................     Disabled

I know the specs on the G.Skill are 2.0-2.1V so I'm at the top end of spec. Other than that, I can't figure out why these settings won't boot.

The following adjustments allow me to POST but not boot:

CPU Voltage..................... 1.35000V
CPU PLL Voltage............... 1.50V
North Bridge Voltage......... 1.65V
FSB Termination Voltage.... 1.42V
CPU GTL......................... 0.67x
NB GTL........................... 0.67x



I'm concerned about going any higher with the Vtt because I've read in this thread that above 1.40V is dangerous for 45nm CPUs. I'm not too happy about the 1.65V for NB either, but it's what allows me to POST.

The modded settings also allow Memtest86+ V2.01 to Pass with flying colors. I just can't boot Vista.

Any ideas?


EDIT:

OK. I found THIS post and I've tried these settings for my voltage

Here's my new BIOS Config:

This allows me to boot into Windows but prime 95 fails Core 1 immediately.

I feel like I'm getting close to a very nice O/C with tolerable voltages. I just need to tweak it and I don't know what exactly to tweak in order to get it stable.


Sorry for posting two full BIOS settings but I'm trying to provide as much diagnostic information for anyone willing to help me.

Thank you!!
