Help! Tried to OC and messed up

[ElNiNoSt0rM]

I'll make this quick and to the point. I built my PC today with a E6400 proc (2.13 ghz) C2D with 2 gb of patriot DDR2 800 RAM. I went into the BIOS and changed the settings according to a website to overclock, but I think I messed something up along the way. The RAM timings ended up being 6-6-6-16 (I have no idea about this stuff, I was just following the guide) and the CPU clock at 300. I power on only to receive a series of quick beeps and it powers off, eventually continuing repeatedly. Is there a way to clear the CMOS to factory defaults? I don't have a jumper on hand, but will removing the battery do it? I'm open to any ideas, and hopefully not have someone tell me that I've ruined the mobo Thanks guys.

EDIT: Mobo is gigabyte P65 (I think) or something like that. It uses that M.I.T tweaker in the BIOS.

yes remove the battery

Well, I put a jumper over the clear CMOS. Powered on, nothing happened (I'm used to seeing "CMOS has been cleared. Please reboot"

So I take it off, reboot with just the power cable in, and I get a very high pitched squeeling sound which subsides after I power down (but slowly) I might be screwed.

Holy crap, it was the video card not being plugged in. I never knew that it would SQUEAL like that over something like that. Well the CMOS is cleared and all seems to be well. Any advice out there for me to OC PROPERLY and not haphazardly changing the BIOS like I did?

make sure in the settings that FSB and memory speeds are 1:1. 300 fsb should be 600mhz ddr (because ddr is double-pumped, weird huh? ). Maybe read up on a few c2d overclocking articles if you still have trouble

Dont just jump into the BIOS and input some values that some other guy is using, not all chips are the same. Read a good beginners guide and find your limits.

also make sure you have the latest version of the bios. and yes read up before jacking up voltages and mhz's.

Thanks for the help guys. I approached it more carefully this time. My FSB is currently set at 330, which puts my RAM at 660 (2.1 C2D now OC'd to 2.6 ghz). My RAM is DDR2 800, so does this mean I'm not getting the most out of my ram? I did the math, and it appears that I'll have the FSB at 400 (3.2 ghz) to get the 800 from the RAM I had before. I'd love to go that high, but 2.6 is as high as I want to go with stock cooling (41-42*C idle). Any ideas would be helpful.

EDIT: Also, does this look like a healthy OC to you? The default voltage for the E6400 is listed as 1.325, and I've juiced it up over 800 mHz and this hasn't changed, even when I set the voltages to auto in BIOS. Any ideas there or is that normal?

ElNiNoSt0rM, that sounds like a great overclock considering you are using the stock cooler.

If you want to go further, I suggest an Arctic Cooling Freezer 7 or a Zalman CNPS-9500.

Remember that your room ambient temperature and case airflow play a role in the CPU temperatures.

You can test your CPU to see how high it can go without using to much voltage.

Set your FSB to 350. RAM to 700mhz, Manual settings for RAM Voltage and timings (manufacturer specifications) and set the CPU Voltage to 1.35V

If it works, move on to 375 FSB, RAM 750mhz, try the same voltage on the CPU.

If you have a good E6400, it might just do 3 or 3.2ghz with 1.35V or so.

Try it!
