OC not sticking with reboot (e4300)

[rootb33r]

Hey guys I finally got all the stuff to work right and now I want to get my e4300 to 2.5-2.6 Ghz, for now. Small overclock I know, but I'm not OC genius so I'll stick to the basics for now.

My problem is that every time I try to OC, upon reboot the system shuts off, reboots for 2 seconds, shuts off again, reboots for one second, shuts off again, and finally reboots and when it posts it is running at 1.8Ghz again... almost like it reset itself. I kept all the voltages the same and just changed the multiplier to 9 and the FSB to 266 for starters.

motherboard is Gigabyte P35-DS3R
HSF is Arctic Cooling Freezer 7 Pro.
and RAM is the G.Skill DDR2 800

Any suggestions?

p.s. I did read the OC guide... did everything it suggested and still no dice.

Have you set memory unlinked or at a different divider? Maybe it's not the CPU but memory holding you back. If you change FSB to 266 and your mem was set @ 400 linked you probably just overshot the max mem frequency. Don't exactly know how it's called in your BIOS but there are probably some people here with the same mobo, so if I don't make any sense , just wait for them to come in and put it straight.

just set the memory divider to 3.0 and got it to post at 9x276 ... i moved it to 9x290 and it wouldn't post... voltage problem?

nevermind... I think I figured it out. Had to make the RAM go below 800. Sitting at 9x295 for right now

Thanks for the tip

Hey, i was browsing around cause i have the exact same problem as you. same cpu too. i was wondering how you fixed it D:

Right. If you leave your memory settings on Auto, at a stock speed of 1.8 GHz, your memory clock is at 800 MHz. If you increase your FSB freq to 250 MHz for instance, your RAM clock will go to (250/200*800) or 1000 MHz.

The way to fix that is to go into the BIOS, take the memory settings off Auto, and change the System Memory Multiplier to 2.0. This will drop your memory clock back to twice the FSB freq for that "perfect" 1:1 FSB:RAM ratio. Use a utility called CPUZ to check this. Anything greater than 1:1 (larger second number) means that you are overclocking your RAM. Overclocking RAM in a Core2 system gets you little if any extra performance.

It's for an EP35-DS3L.

Uhm excuse me but I've just set my System memory Multiplier to 2.0
I overclocked my fsb by 10 mhz

and the overclock does not stick when i reboot.
for some reason a 1mhz or 5 mhz clockerclock sticks. but when i tried 10 mhz, it did not stick
