Question Easy Way to Verify ECC RAM installed?

I recently got an apparently great deal on an HP ZBook Fury 15 G8 laptop for a great price. The Ebay ad said it has the Xeon W-11955m CPU, which was confirmed by Device Manager. But section in Device Manager says nothing about memory. When I clicked into System & Security it confirmed the same CPU and said I have 32GB memory (the seller said it was 64GB!!), but it doesn't specify ECC or non-ECC.

I know that this can be determined by physical inspection. ECC RAM sticks will have an odd number of chips on them; one of the chips will be for parity checking (?). This video shows a tear down procedure for getting at the memory sticks but it's way too tedious and risky for my liking.

Might there be a way via the BIOS, Windows 10 or other software to confirm whether or not ECC RAM is installed?
 
Run CMD or Powershell with Admin Priv.

Type:
wmic memphysical get memoryerrorcorrection

You will get 2 corresponding numbers.
If you get the value 3... it means nope... your not running ECC.
If you get value of 5 or 6 it means your running ECC.
 
Also, something like CPUz or Hwinfo will give you more information on your RAM.

What"s the 5 and 6, buffered and unbuffered?

There is something wrong there because googling that Part Number brings back DIMM results whereas your Notebook uses SODIMM.

No, that screenshot's just an example posted at the thaipoon burner website! I only just installed the app on my laptop just now. But when I clicked on app launch button I got a warning for "ASUS users". I don't know if my HP ZBook G8 laptop has an ASUS motherboard, or anything else ASUS, so I didn't click ok. I took a screenshot of the notice and saved to a Wordpad file; I don't yet have MS Word on this laptop. But this forum won't accept that format for uploading.

But I did click on a Version document, which said:

"The XMP Enhancer Editor is capable of accessing DRAM controller configuration registers of Intel and AMD processors. The idea is to create XMP profiles on the base of the current DRAM timing settings. Unfortunately, not all Intel processors are fully supported due to the lack of technical documentation."

And below this text, it says

6th Gen "Skylake" Desktop & Mobile Intel CPUs with DDR3 DC mode - tWR & tWTR are not read out;
* 10th Gen "Ice Lake" Model U/Y CPUs - tRC, tRFC2 and tRFC4 are not read out;
* 11th Gen "Tiger Lake" Mobile CPUs - tRC, tRFC2 and tRFC4 are not read out.

Mine is 11th Gen. As a suitable alternative, it looks like HWinfo should be compatible

Is Dram Freq correct in Tiger Lake laptop CPUs with 3200mhz DDR4

I understand that in Gen 11 Intel Laptops (ie i7-117850H) with 3200mhz DDR4 ram, it must run at Gear 2 HWiNFO correctly shows this running in Gear 2. It also shows the dram freq at about 1600 which I believe is correct. However, there is no indication of what the memory controller freq is. In...

Download, install and run HWiNFO64. It has a section telling you what you want to know about your memory modules.
