First time dabbling in overclocking...

So I decided that my i7 950 running at stock speeds wasn't going to cut it anymore for upcoming PC releases till I upgrade next Summer. As a result, I bought 12gb of DDR-3 1600 RAM and I'm also wanting to overclock the stock speed of 2.66 GHz to something manageable between 3.2-3.5 GHz. Since I have never overclocked before, I tried out the Dummy OC option in my BIOS (x58 motherboard) and it set it to 3.2 GHz but my RAM shot up to over 1900 MHz. Checking my core temps in the Intel Extreme Tuner program, I saw my temps go from mid 50's to mid 70's. As a result I changed it back to stock settings as well as my RAM back to 1600 MHz. The RAM is set to XMP but when I turn off the XMP profile and then use the Dummy OC, the RAM only runs at 1233 MHz. For now I only have the stock heatsink and fan for the CPU but I plan on getting the HyperX Evo 212 for it in the next few days. Any thoughts, suggestions, or advice would be appreciated.

1.35 volts is the safe maximum core voltage, my i7-950 didn't need that much to get going.

Basically you have to reset the memory ratio as you increase BCLK frequency. Stock ram frequencies: 8 x 133 = 1066, 10 x 133 = 1333, 12 x 133 = 1600

CPU Ratio will go up to 24, but you can also lower it to get more reasonable numbers.

You can runthe BCLK as high up as 212 if you are lucky, but probably not.

I set the ratio to 10 and the BLCK to 161 and managed to get 3.85Ghz @ 1.125 volts, ran this 24/7 for about two years.

If you are really lucky a ratio of 175 x 24 will fire up and you can run at 4.2Ghz (Ram at 1750 or 1400), Or 200 x 22 to get 4.4 Ghz (Ram at 1600)

Without that CPU cooler though you probably won't get too far.
