A little bit of per IC binning & PCB swapping done so far (but not enough).
Did a quick test of KO PCB with the LN2 board.
For some reason changing bclock from 100 caused POST to fail even at stock, and 2933 strap didn't want to load so not sure if this board hates non-oem g-die, or not. So only Asus boards confirmed to work with 1T, high freq & KO PCB.
REFI doesn't want to move from 10k either, despite being set to 30k. Something is whack with my board...
