A warning:

For you brave souls that have enabled all 8 VRMS (early Octobers) I saw today that the 1.0.0 firmware does not apply the voltage adjustment to all 8 VRMs. It only applies it to the 4 that are officially enabled. The old FW applied this adjustment to all VRMs.

The VRMs work in pairs and if the voltage adjustment (VOUT_TRIM register) of the 2 VRMs in a pair is different things will go bad.

If you still want to use all 8 VRMs I suggest you read and understand the datasheet of the VRM.
The VRMs are very resilient to abuse, but they have limits.


Other than that FW 1.0.0 works very good. HW errors have dropped a lot for me. Good chips are close to 0% errors (2% before), bad chips still close to 2%.
