Overclocking Core 2 Duo E6550

Some time ago I dabbled with overclocking for a while, and had my E6550 running at 3ghz on my ASRock 4Core1600Twins-P35 motherboard. I have searched for and replicated the settings i had as close as i can remember.

I set overclock mode to manual, CPU frequency up to 430, upped the power to the cpu. tried varying the pcie frequency too. But I get no change at all in the cpu speed, it just stays at 2.33 Ghz. I have tried every settings variable i can find.

Is there anything I am missing here?

honestly usually its not the CPU keeping you for OCing further its the rest of the components. If your mobo allows to unsync your ram. Try to set your ram to stock freq, and just OC the fsb on your CPU. It's not really going to speed too much up without the ram going with it, but I on mine I boosted my 2.5 ghz e5200 to 3.7ghz by keeping my ram at stock speed and just boosting the cpu.

that boot failure guard is probably reverting you back to stock speeds (I'm not familiar with that board so that is just a guess)

also if your stock voltage is usually 1.35, that 1.42 seems like it could be a thermal nightmare. which I'm sure you're aware of, but just to air on the side of caution, I figure I'd warn.

good luck, and I hope I didnt confuse you more.

edit: the biggest thing is that you did this before and it worked. if anything is new since (ram, video card) try reverting and testing again as that item can be the bottleneck. But I am still leaning toward your ram not wanting to go any further.
 
If the PCIE frequency is for the video card it is too high. It should be 100. That may be what is holding the oc back.
