OK i see, its the japan one.Interestingly another eBay seller selling the same chip confirms compatibility with AsRock X99 motherboards and some standard C612 mobos. If so this chip is truly a little freak.
if you have luck u get one without scratches on the gold side (but they work)
i got one with and one without.
less power than the 2699 is because only 120w TDP and cutted turbo bin's on ES xeons.
(except the 2630Lv4 ES - this has same stepping and turbo than the retail)
