ZBook Fury G8 ECC Memory and Maintenace and Repair PDF

[mwx]

I found here a link to a Maintenance and Repair as "http://h10032.www1.hp.com/ctg/Manual/c07681129.pdf" which is no longer a good link; however, "http://h10032.www1.hp.com/ctg/Manual/c07681130.pdf"  from the support page works as a user guide. Interactive Part Locator "https://h10032.www1.hp.com/ctg/Manual/c07721773.pdf" is helpful but not a useful in answering whether I can use 2x 32G ECC like MTA18ASF4G72HZ-3G2R in the primary memory slots, or must I use 4x16G ECC like MTA9ASF2G72HZ-3G2R in the W-11955M laptop. Crucial lists these as compatible. Original configuration was a non-ECC L67710-001.Are the paired memory both in primary under keyboard or in separate slots, one under keyboard and the other under back cover?

Without a model number instead of product number there's not much help we can give. Here's how you can check the mem capacity in windows-

Windows users can determine the maximum RAM capacity in the Command prompt (Run as Administer) with the command here- "wmic memphysical get MaxCapacityEX" without the quotes and divide the value by 1024 That will give you the total amount supported by your laptop.

Also, this guide- https://support.hp.com/us-en/document/ish_9756213-9756262-16  may help uou a bit.

 This warning is for consumer laptops, not for the business class laptops.- Don't buy any modules labeled as Performance ram, as there are no XMP profiles in bios to change timings. Also not sure of ECC memory compatibility.

The newer Quick Specs, c07606964.pdf,  states 128G ECC. I had watched a video, not from HP about disassembly that stated 64G ECC, and I know I read that in some other HP document. Today I installed 2x32G in the primary slots, and am planning to try two more soon in the secondary. It would appear the 128G EEC is legit. I was using MTA18ASF4G72HZ-3G2R. If I find anything that would contradict such, I will append.
