USA seller. Will ship overseas with proper payment processing.
Prefer to ship by USPS Priority Mail.
For US buyers: signature required; proof of delivery required; insurance required and all provided in price.
For potential overseas buyers: please inquire.

Asking $777 (>80% off original retail)

Rare Xeon E5-2696 v3 QS QGN7 stepping (CPUID = 306F2)
Top-bin Haswell-EP 18-core / 36-thread HCC slice with 38x max multi and all final OEM branding strings intact.
This chip is functionality equivalent to final release silicon in every way.

Was offered OEM-only and hence not in the typical retail line-up: closest cousin is E5-2699 v3.

Can confirm that the all-core turbo work-around is achievable as published.
This guy seems to know all about it: freecableguy/v3x4

Nerd eye-candy has been attached.

Thank you for looking.

EDIT: Can comment that I have personally achieved as high as ~3570MHz sustained all-core turbo with all 18 cores active. Water-cooling is a must for max performance up to ultimate EDP limit. CPU can and will consume >300W when properly multiplier unlocked.

Pro tip: Sweet spot is to activate 16 of 18 cores for 3675MHz all-core turbo and 3990MHz for just about all other workloads.

What boards would take this?

I highly recommend ASUS X99-A or equivalent.
Can confirm that this particular board will provide for Registered ECC memory operation in conjunction with Xeon and allow for "overclocking."

EDIT: For clarification - X99 (R3: Flip-chip LGA 2011-3) is the platform for single CPU; dual CPU is C612 (dual Socket R3).

Will add you can also pair this with a 2699 v3 of *any* ES2/QS/Production stepping (if you're not lucky enough to find another QGN7) so long as the 2699v3 goes in CPU0 socket and 2696v3 in CPU1 socket.

This CPU is excellent for media encoding AND gaming on the same rig. Make your system a renaissance-system and jack-of-all-trades.

When gaming this CPU will peg all cores to 4GHz (with 105MHz BCLK applied) and will stay there. Only during heavy loading across ALL cores does the multi drop to 34x (with all-core turbo work-around applied). Sixteen (16) to 18 cores crunching @ >3.5GHz will demolish x264/x265 including live-stream encoding for remote capture/viewing.

We all know we don't need 5.345626738GHz for gaming. Couple with 64GB or way more ECC DDR4-2133R and GTX 2080 Ti for unstoppable machine.

High performance cooling required.

I run two of these on C612 with 256GB under custom water-cooling loop. GFX on same loop is 1080 Ti. CPU bench + GPU bench = >1kW sustained.

If the heat goes out, just load up the system and close the door.

Perfect Father's Day gift. :D

What VRM temperatures? Have you full cover water block?
No to full-coverage... CPU only blocks. Separate block for GPU.

VRM can reach 85 to 90C or greater.

Fans from 3x120mm shroud (push/pull) exhaust over length of MB cooling VRM (heatsinks installed by MB vendor) and memory.

Using 6x Yate Loons at 1500RPM. Barely audible.
