First, you shouldn't post your email address in an open forum.
Second, you are going about things backwards.
Third, overclocking memory does not accomplish that much. All it does is pretty much force the memory to wait for the CPU to transfer data.
So, let's start over.
This should be your first stop.

Shadow's Gigabyte motherboard OC guide:

It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.
Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier from AUTO to 2.00B. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 333 MHz, your memory clock should be at 667 MHz.
Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.
Now start the "increase FSB, test for stability and temps cycle, and increase CPU voltage" cycle.
You shouldn't exceed Intel's recommended max voltage of 1.3625 volts or 70 C. Depending on your CPU VID and your CPU's internal multiplier, you'll probably reach a stopping point somewhere around 400 - 450 MHz.
