Just selling my 13900KF now that I've purchased a binned 13900K from someone else.
It has already been delidded with liquid metal.

Will daily 56/45/51 at a reasonable voltage and can handle 4,200 CL14 1T Gear 1 with 4x16 GB Micron B-die at low VCCSA.
Boots up to 4,400 MHz Gear 1 as well. Samsung B-die should do 4,200-4,266 MHz just fine.

Doesn't come with the box anymore. Free shipping with tracking to anywhere in Canada/USA.
Just looking to recover the original cost (in Canada). Hopefully somebody else will enjoy this chip as well :)
