Hi, I know there is a guide to overclocking, but I've been having trouble with this processor. I'm only able to get my fsb to 343 with a multiplier of 9, anything beyond that and my computer wont even post. I know thats a pathetic overclock, and I dont know why I cant push it more. I try to up the voltage and no matter what voltage I change it too it doesnt post. Everywhere I look it says that even on stock cooling usually an 8400 can go to 3.6ghz. I looked at core temp, real temp, and the bios temp and they all say my processor is running at about 40c. Please help!

Here are my specs:
Gigabyte G41M-ES2L
Intel E8400
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Rosewill TU-155 II w/ 500 watt psu
Evga Nvidia 8600 gt
Masscool 92mm Ball Heatsink
80mm and 120mm fans

Please set the RAM multiplier to the lowest setting, and then proceed with the CPU OC. When you OC the CPU, the RAM speed also increases proportionally. By setting the RAM multiplier to the lowest setting, you are eliminating the RAM as the source of instability.

After doing your OC in the BIOS, check for stability, temps, and RAM speed. If possible, now you can increase the RAM multiplier with the new OCed settings without going beyond the RAM manufacturer's specs.

I lowered the multiplier and it still wont boot if I OC the CPU at all. It doesn't post just reboots with the normal settings again.

The changes must be done in the BIOS, then saved - then re-start your computer. (To get into the BIOS, keep tapping the appropriate key while the system is booting - "Delete" key in my case).

You may use programs such as EVGA's ELEET to obtain the OC settings, but these settings must be changed in the BIOS and saved in order to make them part of your system.

I've only used the bios to OC, and after I save the settings it tries to boot but doesn't even show anything on my monitor then shuts off and restarts at the default settings automatically. I'm sorry for not saying I've been trying to OC in the bios.

Here is one user's comments regarding this board "Tested and it works with 8800gt and gtx 260 but not the 9800gtx+. The 9800gtx+ works fine in other computers but not the the gigabyte board. Seems like they dont get along with each other. Contacted Gigabyte, couldn't get a way to resolve the issue".

Time to contact Gigabyte.

Contact Gigabyte about what? That user's problem is completely irrelevant to the OP.

OP: What voltages are you setting? Have you changed the NB voltage? Is it possible to post pics of your BIOS settings?

Unfortunately I dont have a camera to take any pictures. The only voltage settings I've changed is the cpu vcore. It's default it 1.225. I've tried every setting in between all the way to 1.5 and no matter where it still wont post. Its weird because my motherboard wont even post and see if my system is unstable or not, it just reboots to the default bios.

Sigh.

This is about the fourth time within the past 12 months that I have posted about the problems of trying to overclock a CPU with a 333 FSB in a G'byte G41 motherboard.

Enter the BIOS and set the memory multiplier to 2.0. Your memory clock will show 667 MHz. Then increase your FSB.

Here is your problem. The G41 is an economy chipset. I doubt if you can get much past 360 - 370 MHz. Look at the manual on Page 10. It says:
"Frontside Bus - 1333/1066/800 MHz FSB",
unlike my GA-EP35-DS3P manual that says:
"Frontside Bus - 1600 (O.C.)/1333/1066/800 MHz FSB",
or my GA-EP45-UD3P manual that says:
"Frontside Bus - 1600 /1333/1066/800 MHz FSB".

Now, with something like an E5200 or E7200, things are different. The 200 MHz FSB frequency, coupled with the relatively high internal multiplier, gives you a lot of room to work.

A good E8400 with a low VID will run very happily at 3.6 to 4.0 GHz in a GA-EP45-UD3P or L motherboard.

The only voltage settings I've changed is the cpu vcore.

As JSC has mentioned it is a budget board and so I wouldn't expect a great OC, but MB rating don't really mean that much. I've had an Asus P35 board rated at only 1333 and have had it up to 2100.

Your NOT going to be able to OC with ONLY your vcore. Read a few OCing guides to get familiar with the Bios entries. You will need to set at the minimum vcore, fsb, fsb term, nb, pcie, sb, memory strap and speed and timings and voltage, and it would help to set the GTL ref voltages.
