For me, as has been mirrored by a few others, found that with a fixed VCore that is on the brink of stability at a given CPU speed, the higher the PWM switching frequency set the quicker LinX fails.

How much faster were you guys able to run with PWM set at 1000khz compared to 250khz? And with which BIOS version?
I would use exactly your words to describe walking on the edge of stability, but instead using 1000kHz to give it the advantage.
Using BIOS 0601 and difference between 250&1000kHz is unstable rig becoming stable at aimed speed (core 4410, uncore 3780, qpi 3780, mem 1680)

This option is described in the manual as the "CPU Voltage Control [Absolute (VID)]".
bios: 601
I would like to know that too. I didn't even noticed it, before you mentioned (never read manuals much )
