DFI ICFX3200 T2R/G FSB Scaling & Voltage Settings

[The Nemesis]

I've done some extensive testing with the RD600 and have compiled the data into a quick chart to help others in setting up quick overclocks on their board. Memory was left async, DDR2-800, 2T for most of the tests. All testing done on open test bed (HSPC Top Deck Tech Station). North bridge cooled by Microcool NorthPole XE Whisper Chipset Cooler, cpu cooled by Tuniq Tower with stock fan. Your results may vary, but these were the exact settings used to reach each final result.

CPU: E6400 L628B194
Memory: G. SKill 6400 HZ's
Video: Evga 7900GT's
PSU: OCZ GameXtreme 700w
Case: HSPC Top Deck Tech Station

**** Use these voltages & settings at you own risk****


It has been said by other more knowledgable enthusiasts that 1.5v on the nb is the max safe 24/7 voltage.
