Question Issue with RAM configuration on Asus motherboard ?

[sdhineshkumar]

Hi,
I have configured and am using this system since 2018, with below configurations:

MB : ASUS Z10PE-D16 WS
CPU: Intel Xeon E5-2620 V4 2.10 GHz : 8-Core,16-Threads,20MB-Cache, 85W, Server CPU,LGA 2011-3, RAM: DDR4 1600/1866/2133 - 1.5TB
RAM : Crucial 32GB DDR4-2666 RDIMM ECC RAM (CT32G4RFD4266) x 4 = Total of 128GB
HDD : 1TB x 4 = Total of 4TB Crucial SSD Drives

Now I am planning to upgrade the RAM by adding an additional 128GB using this:

SAMSUNG 32GB PC4-21300 DDR4-2666V-R REGISTERED ECC 2RX4 CL19 288 PIN 1.20V MEMORY MODULE ( PC4-2666V-R ) (M393A4K40CB2-CTD6Q)

I just want to know how to add it.

As per MB manual we have to use 4x RAM sticks in DIMM sot - A1,B1,C1 and D1 but when I try to install it is not working it throwing error B7. But when I installed in A1,A2,B1 and B2 RAM(memory)works good without issue, as I said I want to add128GB RAM into C1,C2,D1 and D2 DIMM slots whether to know it will work or not or my DIMM having problem because as per manual it didn't worked,(ie) A1,B1,C1 and D1.

Can someone pls confirm whether you have such issues. Any suggestions are much appreciated.

Well, there's a reason for that. You are using 4x individual RAM sticks, rather than a set of RAM.
The Micron you have, are all individual DIMMs,
unofficial specs: https://www.serversupply.com/MEMORY/PC4-21300/32GB/MICRON/CT32G4RFD4266_294724.htm

Why it doesn't work? Further reading (especially 2nd, "mixed memory" chapter),

And now, you want to make it into a RAM zoo, by adding completely different, additional 4x individual sticks.
Samsung too, are all individual DIMMs,
unofficial specs: https://www.serversupply.com/MEMORY/PC4-21300/32GB/SAMSUNG/M393A4K40CB2-CTD6Q_371640.htm

Do you know why RAM is sold in a set? Including server RAM?

We have 8 DIMMs per CPU; would it work if I use Crucial 32GB DDR4-2666 RDIMM ECC RAM --> A1,A2,B1, and B2, followed by SAMSUNG 32GB PC4-21300 DDR4-2666V-R REGISTERED ECC --> C1,C2,D1, and D2.
First, 4DIMMs will be configured, one set 32x4 =128GB (Crucial), and the second set 4DIMMs will be configured using a different type of memory (Samsung). Will this work?
If this board only supports memory in sets, the RAM vendor or even ASUS must recommend using memory in sets exclusively.
