Trouble with ES Xeon

Taken from this eBay link:

Intel Xeon E5-2630 v4 ES CPU 2.2GHz 10-Core 85W Max 3.1GHz QK3G Supports X99 MB | eBay




So even though it is an R0 stepping for your ASUS X99 motherboard it needs to be a QS or production processor to work properly. The QK3G is an ES2 (I would call it a pre-QS due to stepping ) with identical stepping as production.
What markings do I need to look for in order to make sure that it I'll work with the board? Does it need to be a V3? Will a v4 work with a different board?

V3 ES's don't have an issue with the majority of X99 motherboards it is the Broadwell-EP ES Xeons that have an issue with certain brands of X99 motherboards (such as ASUS, GIGABYTE). If you used that processor in something like an ASRock X99 motherboard or certain MSI X99 motherboards it should be compatible as long as the bios is up to date (especially for MSI X99).

Just found this might be helpful:

Intel Xeon E5-2650 v4 ES 2.2GHz LGA2011-3 12C Compatible with X99 i7-6850K 6900K | eBay

INCOMPATIBLE OR UNSTABLE Motherboards:

Asus X99 Express Chipset motherboards (Only supports assembled or DIY desktop computers): some but not all stuck on Q-Code 19 after reboot; They support v4 series CPUs with B0/M0/R0 stepping, v4 series CPUs QS version or retail version/ OEM version CPUs only.

So I have a working CPU with an incompatible board. I'm trying to weigh the option of new board that works with this CPU, or a CPU that works with this board. Will just about any v3 ES work with it or just the ones on the Asus list? Also all my components are past the point of return.

V3 ES work better with the majority of X99 motherboards including the ASUS X99 motherboards. Take for example the E5-2658 V3 and E5-2670 V3. They should be compatible even though they are early engineering samples.

Otherwise if you want to use that V4 ES the better option is to invest in certain MSI X99 motherboards or the ASRock X99 series.

Here's an example E5-2670 V3 ES (not that it's an ES1):

Intel Xeon E5-2670 v3 ES 2.2GHz LGA2011-3 12C Compatible with X99 i7-5930K 5960X | eBay

Asus: X99 series
Asus: Rampage V Extreme
Asus: Sabertooth X99

I guess it comes down to buying a new board or CPU. Cost would determine that CPU would be less. Do the L and R suffixes to xeons matter to the socket? Before I order one do I need to make sure the numbers on the chip are a certain thing? Can I basically pick any v3?

Does it not also depend on the resale value? - The Mobo might be easier to unload;)

Motherboard is easier to unload but it also depends on demand for that motherboard too. There seems to be demand for the processor as well.

L usually means it's a lower TDP version (ie lower clock speed). They should still be compatible. If you want to be absolutely sure it is compatible with your ASUS X99 II then look for parts that are QS only which are identical to production aside from microcode updates, etc... Examples are E5-2686 V3 QS, E5-2683 V3 QS etc....

I think he was referring to the stepping L0/R0 etc
Well a higher stepping usually means greater compatibility with most motherboards. Take for example the QK3G which has a stepping of R0 versus the QHVK which has a stepping of L0 and is not compatible with certain X99 motherboard brands. To put it into context of that E5-2630 V4 ES:

L0 (first engineering sample) [compatible with certain motherboards and bioses only]
R0 (second engineering sample and identical to production. Can be considered a pre-QS sample) [compatible with most motherboards and bioses due to stepping as long as it supports Broadwell-E/EP]

Haswell-E/EP have different steppings and revisions and differ from Broadwell-E/EP even for ES.

So out of the 10 and 12 code v3 Xeon wich ones will work for my board that are on eBay?
Look at this on eBay http://www.ebay.com/itm/152288669800

Look at this on eBay http://www.ebay.com/itm/162234990342
Xeon E5-2650 v3 ES 10 core 2.1Ghz LGA2011-3
Compatible with X99 i7-6800K 6850K 6950X
Both will work please see sellers notes:

Compatible Motherboards:

Asus: X99 series
Is the ASrock x99 extreme 4 compatible with v4 ES Xeons
Yes it should be compatible even with A0/A1/L0 V4 Xeons.

When you update the BIOS does it update the chipset? Or is that an in OS thing.
The bios does not update the chipset necessarily. Updating the chipset drivers happens in the OS. Bios updates are usually for microcode updates, bug fixes, improvements, etc...
