At wits end. 4 dimms WONT run properly on maximus x formula (macrium reflect errors)

[klepp0906]

Oh god, so without making this as long as a book. My ram has been rock stable for a loooooong time. However ive foolishly spent too many years without backups and began using macrium reflect recently. Who woulda known its a hardcore stability test.

The problem is - my images all fail verification, but only full images, and only to internal drives.

two things allow me to pass verification. 1) write to a usb drive. 2) pull 2 sticks of my memory. 4x8 CMR16GX4M2C3600C18

The ram passes prime. Ive ran hci memtest pro overnight with no errors. I have no issues elsewhere.

After spending not days, but weeks on this, and blasting my disks with many terabytes of written and re written images to test, im spent.

I ended up checking the QVL (and while before i never put much stock in them, now i begin to wonder) and while my memory is ON the list, its only on it for 2 sticks - not 4.

Thing is, ive tried it on auto which bumps the VCCSA/IO up to 1.4+, ive tried knocking it down from 3600 to 3200 at the same timings. Ive tried with my cpu at stock.

Literally the ONLY two things that can get me to pass is pulling two sticks (yes ive tried pair by pair, and in both sets of slots) or using an external drive.

What on gods green earth is going on?

Anybody using macrium and 4 dimms able to verify problem free? I really dont know where to go with this. I certainly wish I could pull two sticks, but I cant. I'm a heavy multitasker and vm user and id hit that wall more often than not.

I have the same problem here:

System (clean install of win 10 1903 with 2.666Mhz on the memory kit):

9900KF (non-oc) with Asus Maximus XI Hero Bios 1302
32GB G.Skill DDR4-4000 CL17-17-37-2N (single kit)
Mode: Mode 1
DRAM Voltage 1,350v
CPU VCCIO Voltage 1,00v
CPU System Agent Voltage: 1,10

I'am using Macrium Reflect Home (v7.2.4440) to backup the Samsung 970PRO nvme ( drive c: ) to a internal WD Velociraptor HDD
(and test another internal HDD drive too).

Sometimes it runs - so i make 3x full backups and then i will get a crc error.

What i found out:

I startet with voltages

CPU System Agent Voltage runs only with: 0,9750v
CPU VCCIO Voltage 1,05v

RealBench 2.56 is the best for finding this error - quickly.

i raised them to:
CPU System Agent Voltage runs only with: 1,000v
CPU VCCIO Voltage 1,10v

- RealBench runs 8hours 32GB perfect stable
- Karhu RAM Test 1.1.0.0 runs 12 hours stable

- BUT HCI MemTest Pro 6.3 found errors.

- i set higher voltages and thought now it works - then macrium reflect will fail again!

I used Macrium Reflect since years without any errors until i own this new system.

Drivers installed: Nvidia 436.15 / Intel MEI 1914.12.0.1256 / Intel RST Version 17.5.0.1017 / Intel LAN cd v24.2 / HP printer driver.

Edit: testing now 2.666 CL17 with intel default voltages..

Hello, maybe the Macrium Reflect Home and WinRAR Error is another error!?

I have the extreme board and since years i put my optical drive on the SATA6 (6) Port (the last one).

This time i checked each drive in the bios if it is correct connected.

But each time i replug it into SATA6 (6) and SATA6 (5) Port.
Then i saw in the bios that the drive is moved from SATA6 (6) to SATA6 (4)
and SATA6 (5) to SATA6 (3) port!

But its physically connected to Port 5 or 6!

I had my CRC Errors on the Hero (the extreme i did not checked it yet)

BUT my idea:

maybe this port bypass IS the problem for the crc errors !?

I did not see any information in the extreme manual that with one NVMe drive in Port 2_1 that this
disable Port 5+6 !?

Is that so?

On the hero board i connected only HDD's to Port 5+6 (no optical drive) and both drives are used for making macrium reflect backups
with verify (and crc errors).

So i can imagine that this port bypass 6>4 & 5>3 can cause problems on large files which are over 10 GB!

What do you think?

This time i only use the SATA 1-4 ports and stay away from Port 5+6.
