BTW, you're the first person to successfully delid a Phenom II X6, chew* tried this in the past and basically called it impossible due to the extremely high probability of breaking off the SMT components surrounding the die. Congrats!

He warned about issues with chips dying at higher voltage when delidded to what appeared to be quick temperature swings and the IHS acting as "a buffer"...but I think bad contact was the real problem.

I'm not saying you can't gain some MHz from a top end board, but I personally don't think the 890GPA-UD3H has a terribly bad VRM.
I actually might still have one of these in the house but I think I killed it running the northbridge IGP at high volts on LN2.


Most likely. Phenom II X4 weren't made this way...

I'm certainly interested.
Phenom II was so much fun -

FX 8000 series are fun too but not quite as satisfying with low IPC and are more fragile.

I'm not the first one to achieve this. To my knowledge, two people achieved it before me.
The first one goes by the name of shrimp

The second one, who inspired me to do this, posted a video on youtube

So I must be the third or so.

Must be a bad contact. I noticed that temps go up and down less fast. So heat transfer should be better. After all, there is direct contact between the core and the waterblock.
