Alright, I can take a good guess on what your cooler is :). Are the temps in your last post accurate to this overclock?

What brand/speed of RAM do you have?

Motherboard?

What is RAM:FSB ratio set to?

What is your RAM voltage is set to?

What is your CPU voltage set to?

lol thats funny
my mobo is ECS NF650iSLIT-A (V1.0) LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard
cpu voltage is stock 1.31
ratio haven't touch so stock also but everest read 16:15 but if I get it to 3.2 it would be even with ram
ram voltage is 1.88 i think
I have G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

and I am locking up on 3.0 so 2.95 stable I know this chip has more to it defently 3.2

Well, I see that you havn't dont much research it this area. Can I see a link to exact memory you have? Many G.skill RAMs require an extra bump in voltage. What is the result of your failure? Won't boot? Crashes at random?

Change to a 1:1 FSB:RAM ratio. This will underclock your RAM temprorarly. Then when you bump up your FSB the RAM is going up with it. FSB would need to be 400 to get the RAM back to 800Mhz speed. That would make you e6750 OCed at 3.2Ghz.

If you are still having problems and it doesn't appear that it is the RAM limiting you then it is time to bump the Vcore. Use the smallest increments that your board allows.


Edit: Changed a very confusing sentance (don't know what I was thinking when I wrote it).

Do not increase the Vcore if you don't know what you doing. I'm assuming you're on the stock cooler. If this is the case, increasing the Vcore will result in an increase in temperatures, which could potentially harm your hardware if not watch closely as the stock heatsink isn't designed to cool a CPU for anything else then stock settings. The stock cooler will only get you so far, then you're going to have to upgrade you're cooling system.

This is a bit dated but you should read this: How to Overclock
