Mac Pro (2013 Trashcan) Every Slot Every module fails test 10

[nauzers]

Hello all.

I bought Mac Pro for my music studio to work with audio.

MY MAC:

Mac Pro "Quad Core" 3.7 (Late 2013) 3.7 GHz Q. Core Xeon E5-1620v2

Intro. October 22, 2013* Disc. April 4, 2017**
Order ME253LL/A Model A1481 (EMC 2630)
Family Late 2013 ID MacPro6,1
RAM 64 GB VRAM 2 GB
Storage 256 GB SSD Optical None*

I was having random crashes in Logic Pro - beachballing on screensaver wakeup etc.
I decided to test my rams with memtest86. Straight away i got many errors and without hesitation assumed they are bad and replaced them (as I was about to upgrade them anyway).
But the problems remain. System is not stable and every now and then I get crashes and freezes.

Now I test each ram seperately and the results are..

RAM 1 SLOT 1 TEST 10 3078 errors
RAM 1 SLOT 2 TEST 10 3078 errors
RAM 1 SLOT 3 TEST 10 3078 errors
RAM 1 SLOT 4 TEST 10 3078 errors

RAM 2 SLOT 1 TEST 10 3078 errors
the rest are being tested still...

I contacted RAM supplier and they advised that all modules were tested and there is no way all 4 are bad. And most likely my CPU or CPU Riser Card is faulty. (seems to be common issue with these Macs)

I wonder why all my RAM modules are failing Test 10 with 3078 Errors.

Has someone had a similar issue? Could all my modules be really faulty???

I will appreciate any support and will be responding to any suggestions / questions.

Regards,
nauzers

Particular Mac UEFI boot ROMS have bugs in them. See above.posts.
We reported the issue to Apple, but they never replied. Seems they don't care.

Hello David.

So does it mean RAM modules are fine?
