Right now I have the following but as soon as I go to 9.5 multi, it is unstable:

Robust Graphics Booster ...............: auto
CPU Clock Ratio ..........................:9
Fine CPU Clock Ratio.....................:
CPU Frequency ...........................: 3.6GHz

CPU Host Clock Control..................: [Enabled]
CPU Host Frequency (Mhz) ............:400Mhz
PCI Express Frequency (Mhz) .........:100

C.I.A.2 .................................:[Disabled]

Performance Enhance...................: [STANDARD]
Extreme Memory Profile (X.M.P.).....: Disabled
(G)MCH Frequency Latch...............: [Auto]
System Memory Multiplier ..............: 2.0D
Memory Frequency (Mhz) ..............: 800
DRAM Timing Selectable ................: [manual]
Is running at 1:1

Standard Timing Control
CAS Latency Time........................5
tRCD .........................................5
tRP'...........................................5
tRAS..........................................18

CPU
Load-Line Calibration: Enabled
CPU Vcore….……….........................:1.3625
CPU Termination…..... 1.200V*.......: 1.24v
CPU PLL…………………....1.500V*.......: 1.57 (this is the next notch about 1.5)

CPU Referen.&#8230;&#8230;&#8230;&#8230;....0.755V*.......: 0.760<<< .64% Of Vtt (Termination above) Auto ?

MCH/ICH
MCH Core&#8230;&#8230;&#8230;&#8230;&#8230;.....1.100V...........: 1.2v
MCH Reference&#8230;.&#8230;&#8230;.0.800V...........; <<< Leave (current is set at 0.760v Auto)
MCH/DRAM Ref.&#8230;......0.900V...........: <<< auto
ICH I/O&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;.....1.550V............: <<< 1.5 auto
ICH Core&#8230;&#8230;&#8230;&#8230;...&#8230;&#8230;1.100V............: <<< auto

DRAM is @ 2.2v

CPU Host Frequency (Mhz) ............:400Mhz - raise this, and adjust voltage settings as needed.

you need to give a bit more details, other than it is unstable. What have you tried, what type of stress testing, any BSOD, freezing, reboot, etc.

Don't be afraid to increase vcore to 1.4v or higher.

I would get a BSOD when doing IBT or other stress testing (like OCCT linpack and such). Also Prime95 would fail almost immediately on Core 0 e_e.

I have tried increase the vCore to 3.8125 (and anything lower it is completely unstable) and increased my Termination to 1.28. I am afraid of going any higher than that. My temps at 3.8 w/ vCore of 1.38125 is 70C!!!!! Do I need to reseat my S1283 heat sink?

Update, just increased the voltages on the CPU and up to 1.375 and it was more stable (I was able to run IBT without a BSOD) but my temps were crazy. In Speedfan, they got up to 75C and in RealTemp, they got up to 70-72C! I am going to knock everything back to 3.6 since things are too hot.

I believe so... e_e

Yeah, they are disabled and I do not have speedstep.... So do you think I need to reseat my heatsink?

unfortunately, you may have gotten a bad processor. If your ram isn't holding it back, your motherboard definately isn't, and that leads me to assume (from the settings you provided) that your chip may just not be up to it. At 400MHz fsb, mine is stable, even with an older board and slower memory.

Actually, that's gotten me thinking. What is the VDimm? (voltage on the memory). I know my OCZ stuff isn't stable under ~1.95V at 400MHz (well, 800).

I know this may sound crazy, but I've actually had some sticks run better on lower voltage.
