I have two of these cpus.
Both have the same pcie issues.
Tested systems:
HP Z440, and an Asrock X99 (stock newest updated bios!)
Both boots but only with a very old video card (like GT240, 7300GT) but no screen or boot with much modern cards (GTX580, HD6570). The HP system only works when i use the upper 1x pcie 2.0 slot that wired from the PCH not from the CPU. NVME SSD not working or not even an option in the Asrock X99 board.
So that means the two cpu somehow have buggy pcie lanes. I don't think that is completely missing the lanes because there was no crippled cpu in this platform this way.
I think it is something to do with the mmio, vmx, txt or any other feature.
There is no issues when i use regular v3 or v4 cpus in these systems.
Do anyone information about this issue?
I really don't want to send them back if i can solve it with some bios settings.
It is a QS cpu not an ES.

I saw you also posted this on the official Intel forums (you're very unlikely to get anything but a reprimand there, they don't touch ES/QS chips), but that's because I went to Google. Half the posts about it are yours.

There's practically zero information on these processors other than they are custom orders made for Amazon's datacenters and meant to be used exclusively with AWS cloud instances, how you got a hold of these is remarkable.

Do you have another, retail LGA2011v3 motherboard to test them with? Info I found says that they will work OK on Supermicro server boards, as well as (at least ASUS and Gigabyte) X99 consumer grade boards.

OEM workstation boards such as the one from the Z440 tend to be very moody because they have a lot of sanity checks throughout the boot process and are designed to work strictly with validated CPUs, and this one was never meant to be used on anything but AWS blade servers.

I always buy rare things.
Same issue in Asrock X99 extreme, so i think this cpu-s have limited or none pcie lanes.
It is possible, because it is a 4 way cpu for amazon web services. So i think there is no need for any pcie lanes, just for QPI links. (or it has some custom wiring or addressing for the pcie lanes pins)
I will RMA one of them (i have two of this) and exchange it for 2683v4 that is almost the same cpu, same price in that shop, just lower TDP and turbos.
I will keep one for later testing or sale.
