nope. Overclocking takes time to test it out so have some patience and keep raising. I don't care for gaming so I use 3dmark06 to test my stability, but since you game just pick your favorite game and play for alittle bit and go back and raise the clocks again. Just make sure you keep an eye on the temps of your cards. If they get hot go raise the fan setting again. Once you find a spot thats not stable, back down 5-10 mhz. If you find the noise unbearable then leave it where you find it comfortable and try to find the max overclock for that fan setting. Good luck and let me know how it goes
