PC Components are as follows:
Mother Board: ABIT IN9 32X-MAX LGA 775 NVIDIA nForce 680i SLI
Case: COOLER MASTER Stacker 830 Evolution
Processor: Intel Core 2 Duo E6850 Conroe 3.0GHz 4M shared L2
Ram: OCZ 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Power Supply: PC Power & Cooling Silencer 750 Quad (Black)
Graphics Card: Shader OC 1650MHz MSI NX8800GT (2 in SLI)
After Market Heat Sink Fan (for Processor): Tuniq Tower 120 P4 & K8 CPU Cooler

I am having trouble running windows and Prime95 (without freezing) stable @ 3.6 GHz for more than a couple of minutes.

I decided to go with BIOS version 1.4 as several people seem to be having good results with it thus far over at the ABIT boards -

My BIOS (version 1.4) settings thus far are as follows:
OC uGuru Utility Menu:
SLI - Ready Memory - Disabled (is this correct? What does this feature do?)
CPU Operating Speed - Linked (what are advantages of linked and unlinked?)
FSB <QDR> - 1600
Multiplier Factor x9 (i am pretty sure I can't touch, E6850 locked at x9)
FSB: Memory Ratio - Sync Mode
N/B Strap CPU As - PSB1333 (should this be PSB1333 or By Cpu?)
NB PCIEe x16 Clock - 100MHz (don't want this increasing proportionally w/ OC)
SB PCIEe x16 Clock - 100MHz
SB PCIEe x8 Clock - 100MHz
SPP<-> MCP REF CLOCK - 200 MHz (what is this?)

Voltages Control Sub Menu:
CPU Core Voltage - 1.45V (this seems pretty high for only 3.6 GHz, and I still can't keep the PC stable)
DDR2 Voltage - 2.1V (I have seen some people hit 4.0 GHz on air with 2.1 Voltages. I tried 2.2V but still unstable)
CPU VTT Voltage 1.2V
NB Voltage - 1.35V (when should you increase this?)
SB Voltage - 1.5V
HyperTransport Voltage - 1.2V

Advanced Chipset Menu
Memory Timing Setting Submenu
Memory Timing Setting - Manual (not auto)
tCL (CAS Latency) - 5
tRCD - 4
tRP - 4
tRAS - 15
CMD - 2T
Advanced Memory Settings - Auto (should I manually set this? If yes, how do I find the associated numbers for the tRRD, tRC, tWR, tWTR, tREF, and tRFC fields?)

Here are some threads I have already visited (I did use the search button before posting ;) )

Before Windows Freezes, the CPU idles at 39 and loads at about 50C.

I have had no problems running the OS with the CPU at stock at 3.0 GHz.

I was hoping to shoot for a 3.8 GHz 24/7 stable OC. Is that realizable with my given hardware mentioned above?


I should note this is my first OC ever and I am a complete n00b at this. I tried to read as much as I could on my own before posting. Thanks in advance for any help you can provide. I figured I would post here as I am guessing much of your OC process is related closest to your Motherboard. I was hoping to not only attract the community as a whole but also, specifically IN9 32X, E6850 users.
