Overclockers want second revision. :)
"It was found that the GTL Reference Voltage, derived from CPU
VTT/FSB Voltage, on the 680i SLI Motherboard
, needed a little boost for better FSB overclocks on Kentsfield Processors
. About a 0.03v-0.05v boost should yield better FSB overclocks on a Kentsfield Processor
. Current boards do not have this implementation, but newer boards should be tuned with a little more GTL Ref Voltage with Kentsfields. Perhaps we can expect a Revision 2 of 680i SLI Motherboards..."
