E8400 OC problems

I built a budget computer which i was hoping to OC just a little bit but every time i raise the FSB by even 1 the computer does not boot up. Its an e8400 (333 x 9) @ 3.0 ghz on a GIGABYTE GA-G41M-ES2L Mobo ( - newegg link

What am i doing wrong?

U decide to OC a 1333mhz FSB CPU on a good basic value motherboard,but is a basic value motherboard.Anyway, what are the full specs of ur machine for a better knowledge and understanding of the problem. Btw, this board can do nice OC, but i think that the 1333mhz is her safe limit for FSB. Officially is not supporting a higher FSB freq. over 1333mhz.

Wait what??? The FSB is at 333 mhz, the default.

Ram: 2 GB DDR2 800
Video card: GTX 260 core 216 OC
PSU: ABT Kingwin 550

November 30, 2009 7:03:11 AM default speed ,default FSB....Take example my mild oc, for a smoother function of my pc with no dramatic increase of energy consume.

Intel E8400 CPU stepping A rev E0
Core speed 3420 MHz
Multiplier X9.0
Bus Speed 380 MHz
Rated FSB 1590 MH
My Mobo aloud me to reach a max of 1600 MHz FSB but i have to increase VCore for like1-2% increase in performance,so i take 1590 stable 1.2 v. Is not a OC beast,but is a good,stable,reach featured,cheap board.
Take this link for other infos:
Or google for some reach featured OC guides.

The G41 is a pretty good overclocking board for the 65 nm C2's with their 266 MHz FSB freq. and not so good for the CPU's with a 333 MHz FSB for the reasons that technuttso gave above.

I have one that worked pretty well with an E5200 (200 MHz FSB, 12.5 X internal multiplier). With an E8400 and its 333 MHz FSB, YMMV. (Your Mileage May Vary) :)

So it is not possible to go above 1333 mhx FSB? Oh well

Remember, the GA-G41M-ES2L is an economy board. The Gigabyte P35 and P45 boards are an entirely different matter. They are good overclockers. I have three of them.

GA-EP45-UD3P | Q9550 OC'd to 3.6 GHz (425 MHz X 8.5)
GA-EP45-UD3L | Q6600 OC'd to 3.6 GHz (400 MHz X 9)
GA-EP35-DS3P | E5200 OC'd to 3.78 GHz (315 MHz X 12)

All three systems are inside Intel's voltage and temperature limits at load and all are 24 hour test Prime95 stable.
