Trying to run e6400 @ 2.67ghz 333mhz FSB (or better), stock fan. Anandtech got to 360mhzFSB or something on a stock fan easily, without much voltage add. I can do it, but giving my ram 2.2V, and dropping it all the way down to DDR533. This shouldn't take that much, my ram is the well-reviewed G.Skill 2x1024 5-5-5-15 DDR800. It's not ocing past 300FSB though. Any ideas? (also a little worried about having to give it that much juice). Unlucky sticks maybe?
 
If you're dropping it all the way down to DDR533 and running at 333mhz, you're underclocking your RAM. If you're having problems with your memory, it's not unlucky sticks, they are defective since they aren't even running at stock speeds.

Probably an unlucky CPU.
 
could you list your motherboard possibly??? some of them have faulty pci-e locks or other issues that thwart high fsb's. possibly need to bump up your pci-e to like 120 and see what happens
 
If it's an nForce 4 or 5 based motherboard, the max FSB tends to be around that amount. There are also several budget boards based on other chipsets that tend to be poor overclockers.
 
Can you drop the multiplier on that board? See if your board is somehow limited to 300mhz FSB. If you can't go 300x6 or 7, then it's a motherboard issue (bios revision? settings?)
