Hi, I am a newbie at overclocking, but I would like to achieve an overclock of 3.8 Ghz. :confused:

My CPU and RAM are:
Core2Quad Q9550
OCZ Reaper HPC 4GB (2 x 2GB) DDR2 1066 (PC2 8500)

I am currently running at 3.4 Ghz nice and stable. It's set at 1.175 Vcore with all the other voltages at default, and I didn't touch the advanced BIOS settings.


Code:
*************************************************

Robust Graphics Booster [Auto]
CPU Clock Ratio[8]
Fine CPU Clock Ratio [.5]

*********Clock Chip Control*************************

CPU Host Clock Control [Enable]
CPU Host Frequency (Mhz) [400]
PCI Express Frequency (Mhz) [100]
C.I.A 2 [Disable]

*********Advanced Clock Control*********************

PCI Express Clock Drive [700]
CPU Clock Skew [Default]

*********DRAM Performance Control******************

I'm still very new to this overclocking process, so I would appreciate any help of reaching 3.8.

Thanks :D
 
Well, I would read the overclocking guide first....(Its a sticky created by GRAYSKY). Then continue on your way! Cookie cutter settings from say my system (if I had the same processor) may not work.

Some helpful advice in the meantime:

Set CPUt/CPU PLL/MCH core manually. (1.3, 1.5, 1.26 respectively)
Turn on LLC that will help you vdroop you are experiencing.

Those voltages may be a bit to much, but that is part of the tweaking process

I've been reading that guide for awhile, and I had a few questions.
Is there really a "better divider" or is it better to do 1:1?
Could you explain LLC? because I've read of some people enabling it, and some people not.
 
Stick with 1:1 for now. O/c one thing at a time to the best of your boards abilities. Also note, running your ram faster than 1:1 wont increase gaming performance only synthetics.

LLC = Load Line Calibration. When you set your voltage in the bios. You typically have what is called Vdrop. example: 1.25 setting in bios gives 1.20 in cpuz at idle. When you put a load on the CPU, it drops to 1.17, that is vdroop. LLC helps to battle Vdroop. I used it on all my boards but some rare boards dont like that feature enabled. Ours is fine with it.
