Q9550 OC Tips

[d3athsd00r]

My Q9550 2.83GHz has been running pretty stable at 3.74GHz for the last two years, but last night I decided I wanted to get it to around 4GHz if possible. However, I've forgotten pretty much everything I had learned about OCing. I was able to get it to boot at 4GHz and 3.8~ but it would freeze not long after reaching the OS, so I've reverted to my 3.74 for now. I've tried increasing my CPU VCore to around 1.35V with the max safe being 1.3625, lowering my RAM back down to 1600MHz, lowering RAM FSB to 333MHz and 300MHz, and slightly increasing DRAM timings, but to no avail.

 

If any one can give me some tips on what to do to help, I would greatly appreciate it. Here are my settings for my CPU (Cooled by a coolermaster V8), GA-EP45T-UD3P mobo and my 16GB Patriot Viper memory.

 

Robust Graphics Booster: Auto

CPU Clock Ratio: 8X (Max)

Fine CPU Clock Ratio: +0.5

 

**Clock Chip Control**

CPU Host Frequency (MHz): 440

C.I.A. 2: DIsabled

Advanced Clock Control: CP0 Clock Drive [800mV]

PCI Express Clock Drive [900mV]

 

**DRAM Performance Control**

Performance Enhance: Standard

Extreme Memory Profile: Auto

System Memory Multipler (SPD): 4.00D [D=400MHz FSB]

Memory Freq: 1760MHz

CAS: 9

tRCD: 9

tRP: 9

tRAS: 24

Advanced Timing Control: All subsettings are default

 

**CPU Voltage**

LLC: Disabled

CPU Vcore: 1.31250V (1.21250V Default)

CPU Termination: 1.24V (1.2V Default)

CPU PLL: 1.5V (Auto)

ICH Core: 1.4V (1.1V Default)

 

**DRAM**

DRAM Voltage: 1.68V (1.5V default)

DRAM Termination: 0.75V (Auto)

CH-A Data VRef: 0.75V (Auto)

CH-B Data VRef: 0.75V (Auto)

CH-A Address VRef: 0.75V (Auto)

CH-B Address VRef: 0.75V (Auto)

 

Cheers All

And happy weekend.

Coolermaster V8 isn't a cooler with which you can get to 4GHz mark. You will need watercooling.

I'm not a huge CM V8 fan either but my Q9450 made it to 4.0ghz with TRUE in push/pull.

 

OP, what is the bluescreen saying?? like the 0x00000###

True black is better than V8 and with push-pull setup, it is way better.

No bluescreens. Using Fedora 17. It just freezes when it makes it to the GUI.

Might not be getting 4GHz then :-(

Trying not to spend any more money on this build. Trying to wait until Intel releases Haswell before I do some major upgrading.

^^ Then be happy with ~3.6.
