Specs: 11, 22
so intel says never to go above 1.65v on ur dimm voltage for i7... lame
are there such requirements for amd processors? where can i find them?

The i7 uses DDR3 which has different voltage requirements than DDR2.

DDR2 RAM that conforms to the JEDEC spec runs at 1.8v. The JEDEC spec for DDR3 is 1.5v. So why is the 1.65v limit "lame"? Higher voltage doesn't mean higher speed, it means higher temps & a higher chance of failure.

You need to stop asking lame questions & start doing some research. You work a a computer shop, right?

yeah well i figured it was because the memory controller was on the i7. i asked because last time i built a pc i used ocz ddr2 1066 and maxed out the limit which according to ocz is 2.1v, and got my memory running at 1147.
why would intel even mention a dimm voltage limit if it were completely up to the memory manufacturer?

If RAM doesn't comply with the official JEDEC voltage spec, there's a reason.
