Help overclocking in bios

I'm having trouble overclocking my q6600. Im using a gigabyte g41m-es2l mb with a Sunbeam CR-CCTF92-4 92mm Core-Contact Freezer CPU Cooler. Im using windows 7 rc.

Every time I do the slightest overclock in the bios, even just 2.5, the pc wont start. I am able to to get to 2.8 easy using easytune so I believe my system is able to handle the overclock. This is strange, i would really like to figure out what is going on. Any help would be much appreciated.

Stay away from overclocking apps and practice in the bios.....

I built a computer for my sis-in-law using that motherboard and an E5200. Don't remember all the BIOS settings available because that computer is 9 time zones away.

I have a Q6600 in a GA-EP45-UD3L running at 3.3 GHz. It was running at 3.6 GHz when it was in my gaming machine until I built a PC using a UD3P and a Q9550. Then I decided that because it is not in a gaming machine any more, I do not need to push the chip as much.

Here are my settings (based on a CPU with a 1.2625 VID):

Robust Graph Boost [AUTO]
CPU Clock Ratio [9X]
CPU Host Clock Control [ENABLED]
CPU Host Freq. [367 MHz]
PCI Express Freq [AUTO]
CIA2 [DISABLED]
Advanced Clock Control - Default values

DRAM
Perform Enh [STD]
XMP [AUTO]
GMCH [AUTO]
SPD [2.00B]
System Mem Freq 734 MHz
Lets me run CPU: Mem ratio of 1:1
DRAM timing Sel [AUTO]
My mem SPD sets 4-4-4-12
Advanced Timing Control - Default values

Loadline Cal [ENABLED]
CPU VCore 1.2625 V [1.3000V]
The first voltage is the VID, can't change it
The rest of the CPU related voltages (CPU, MCH, and ICH) are set to [AUTO]

DRAM Voltage [2.10 V] - use manufacturer's recommendation.

Keep in mind that these settings worked for me.
YMMV
----------
Overclocking since 1978 - Z80 (TRS-80) from 1.77 MHz to 2.01 MHz

my settings are as follows
Robust Graph Boost [AUTO]
CPU Clock Ratio [9X]
CPU Host Clock Control [ENABLED]
CPU Host Freq. [280 MHz] I really can only post if im at 266 but if im at 280 these are the settings i would choose
PCI Express Freq [AUTO]
CIA2 [DISABLED]
Advanced Clock Control - Default values


DRAM
Perform Enh [STD]
XMP [AUTO]
GMCH [AUTO]
SPD [2.00B]
System Mem Freq 560MHz
Lets me run CPU: Mem ratio of 1:1
DRAM timing Sel [AUTO]
My mem SPD sets 5-5-5-15
Advanced Timing Control - Default values

Your BIOS settings (as in names/function, like SPD, FSB,etc) will be the same/smiler.

You may need to wipe the hard drive and reinstall the operating system.

Send us your BIOS settings ( found in M.I.T.) and we will see what we can do.
Whoops.

Quick question, what BIOS version?

check your voltages that your program is using, you may be killing your cpu by using it.

voltage is good so are temps. and like i said solid as a rock

again i tried a lot but here is one
my settings are as follows
Robust Graph Boost [AUTO]
CPU Clock Ratio [9X]
CPU Host Clock Control [ENABLED]
CPU Host Freq. [280 MHz] I really can only post if im at 266 but if im at 280 these are the settings i would choose
PCI Express Freq [100]
CIA2 [DISABLED]
Advanced Clock Control - Default values


DRAM
Perform Enh [STD]
XMP [AUTO]
GMCH [AUTO]
SPD [2.00B]
System Mem Freq 560MHz
Lets me run CPU: Mem ratio of 1:1
DRAM timing Sel [AUTO]
My mem SPD sets 5-5-5-15
Advanced Timing Control - Default values

VCORE ive tried 1.275, 1.325, 1.385
again I will post if i use these settings but leave the fsb stock.

in the utl i just change to fsb to 333 and memory to 666 and vcore to 1.385 and its runs cool and solid. i got up to 60 max stressing it

Finally, with enough tinkering I was able to post with CPU Host Control enabled. I am now stable at 3.0. The trick was to pull out one of the two 2gb ram sticks. Then change the memory freq multiplier to 2.5. Now I can overclock just fine. One problem for me is I would really like to use all 4gb of ram. I'm running windows 7 x64 and the extra ram seems to help. Do you guys think it is defective ram or is there a trick to adding more ram after you get a stable oc. Thanks to everyone for all the advise and help. I can finally go wash the paint off my forehead that I got from banging my head into the wall .

I don't see anything wrong with this 4gb of corsair memory provided I can get it to post with a cpu oc. Right now the system is running at

cpu feq 333
ram feq 832
clocks 5-5-5-18
vcore 1.25
ram vol 1.8


It will post and run stable with 2gb but won't even post with 4bg. I don't see any setting to up my nb voltage controls. I don't know what to try at this point. Tried messing with the ram feq and volt to no avail. Let me know if you have any ideas.

Stick with DDR2 800. It's the same thing as the DDR2 900.
