I've just upgraded to 96Gb of ram in my 2009 Mac Pro 4,1 > 5,1 upgraded to latest 144.0.0.0.0 firmware and Mojave.

This is ram : https://www.pcbitz.com/products/237...g72pz-1g4e1le-pc3l-10600r-1333mhz-ecc-memory/

What's the best way to test that ram is functioning correctly?

I tried Apple Hardware Diagnostics - restart holding down D key, Alt-D and even original installation DVD with Command D ... but none work.

Any suggestions?

How will i know if the ram is 100% compatible and working 100%?

Thanks in advance ...

Install AHT to an USB-key, read to know how to download and install:

AppleHardwareTest

You will need an Apple OEM GPU to test, since AHT/ASD requires pre-boot configuration support.

I use Atomic but it's pretty intense. TechTool Pro tests free RAM only — but when you need to know how much is available, it's excellent.

The good deal is TechTool Pro Fall collection @ $59.98. It includes Atomic, TTP 11 and Drive Scope (if you really, really need to know the state of your drives). Buy now and you'll get a free upgrade to TTP 12 when it's released after Catalina.

These are the tools I use.
