400 KHz, idle VCore - LoadLine OFF



800 KHz, idle VCore - LoadlIne LVL2



800 kHz, LoadLine ON - Cinebench xCPU



DDR3 - 1.7V Load



This VRM is tuned extremely great! Max ripple at any load was +/- 50mV which is really great result ...

First impressions: solid board, 222 BCLK on Air with pretty old C0 Core i7-920 set directly from BIOS to OS and SuperPi 32M ... later will test with Core i7-990X and some cheapest Xeon under LN2 ...

BCLK Buttons really works, but not with higher BCLK then 220 MHz ... maybe problem of old bios?

Problems: Plastic pins on VRM heatsink - bad contact with mosfets! Plastic pins on High-end board?

No actual Voltage readings in BIOS ...
