cpu: xeon e5 2686 v3 , 18 core/36 threads, bios/uefi driver modded to boost turbo all cores to 3.1ghz instead of 2.3, while 10-12 cores can boost to 3.65ghz simultaneously, instead of the 2-3 default to 3.5ghz.
NOTHING else changed in bios, except bclk 103 and vcore- adaptive. also throttle stop's power cut feature enabled to go with the mod.
original tdp: 120-144 w, currently unknown tdp under stress due to uefi trickery which disabled it.
The UPS software, reporting load from the 1500va/w UPS is showing idle to load differences of 15% (16% ups load idle, fully stressed cpu is 30% total power), so around 200watt of power difference between the two, cpu only stressed.
Temps are fine(70 ish-75, prime95 could be around 80c)

I should note the mod undervolts the cpu by 50mv.

So during gaming or otherwise prolonged use, should I worry about tdp reliability wise?

The Xeon E5-2679 v4 has a 200W TDP and is officially supported in 2011-3 boards, so the socket is officially capable of delivering at least 200W, but also much more, as an overclocked 6950X easily draws more than that. So don't worry about it, you should be fine.

But you made me curious, where did you find that BIOS mod?

Thank you very much!, right on the money and a clear and good answer.

to answer your question, the mod involves stripping microcode from bios, flashing, adding a ufi command to boot order which sets turbo to all cores max, then removing ucode from windows, and inserting the latest one via vmware tool.
You can find it on anand, what controls turbo in xeons.

For now, not too much heavy transcoding or workstation stuff at all, but I am a power user with many virtual machines, large files, extracting, compressing, heavy caching and multitasking, trust me I enjoy the cpu very much. Needless to say it cost me 350$, so a win win.
