Anyone using powerchips 2x2GB kits like gskill, mushkin redline, ocz, etc etc on an older P965 chipset?

As far as I know, these chipsets are limited to a TRFC of 42 in bios and cannot be raised. As most people know, the key to OCing 4GB kit is loosening the TRFC setting to 52 or higher.

I have an Asus Commando and was wondering how far these 4GB kits can be pushed while maintaining 100% stability.

Thanks
