overclock a E6320

Hello I am new in the o / c and I have some small problems.
First my config:
Motherboard: GA-965P-S3 with F13
Processor: Intel Core 2 E6320 1.86 Ghz
Ram: Super Talent 2 * 1024MB DDR2 667Mhz
Graphics Card: nvidia 9800 gtx +
I have a water cooling for the processor

overcloker processor without too has affected the ram
For the moment I put the ram in 1:1 and I installed the 2.33 Ghz processor except that my fps are down dramatically.

• Cpu-z says: core speed: 2331.1 MHz
• Multiply: x7
• Bus speed: 333MHz
• rated FSB 1332 mhz

Where are the loss of performance?
Thank you in advance for your answers

You mean that your games have lost your fluidity after overclocking?

Yes and that's when I like hands before games become fluid.

If you change the FSB mhz one

So I put the FSB 267 * 7 which puts me at 1.87 GHz instead of 266 * 7 (1.86GHz) and I put the ram in the car and no problem of liquidity

If you leave the ram in the car and you pass the 333MHz FSB?
