List of X99 motherboards compatible with ECC memory ?

[Riok]

Hello,

There are two types of X99 motherboards compatible with ECC memory:
- The ones officially compatible
- The ones not officially compatible

If you have tested your board with ECC memory, please report it here. (With Memory serial number and bios version if possible).

It's just about ECC or REG ECC compatibility, not necessarily having the error correction actually working.

Officialy compatible

ASRock Fatal1ty X99X Killer
ASRock X99 Taichi
ASRock X99 Extreme 4

MSI X99A RAIDER
MSI X99A TOMAHAWK
MSI X99A SLI (Not the plus version !)

ASUS X99-E WS
ASUS X99-M WS

Un-Officialy compatible

All tested ASRock boards - Reported compatible here.

Boards in the MSI X99A line list the xeon as being compatible so chances are ECC also is.

All tested ASUS boards - Reported compatible here.
ASUS X99 Deluxe - Reported compatible here.
ASUS X99-a 2 - Reported compatible here.

MSI X99A Gaming Pro Carbon - Reported compatible in this thread

Yeah, I'm running a e5 1650 v4 2400mhz RDIMM 128gb on my board. ASUS X99-E WS 3.1 USB
Bios 3601
Here's a link to the memory i'm using. I bought these when they were a lot cheaper....

These chips are outrageously priced now.....

CPU: Xeon E5-1650 v4
Board: ASRock X99 Taichi
Memory: 256GB comprised of 8 sticks KVR21R15D4/32 (ECC Registered 32GB 2133MHz).
Before picking this memory set - I've successfully booted the system with a single stick KVR24R17D4/32 (2400MHz equivalent), but due to limited stock had to fall back to 2133

Bump! I have an X99 Deluxe with a 1660v3, and I am thinking of upgrading it with some 32GB RDIMMs. Unfortunately, they are still not very cheap.

A small update here, I got a deal on a set of used Samsung DDR4 2133 ECC RDIMMs, for a total of 256GB (8x32GB)! Installed them all in the motherboard, and it works just fine, my CPU OC is still working even! Memtest86 was done with 4 passes, took nearly 2 days though.

Funny thing though, the first time I booted Windows 10, I noticed the boot drive, a 512GB 950 Pro, was almost completely full. Turns out Windows had supersized the page file LOL. I was sure to fix that.

@aigomorla I figured you might be interested in this. If the X58 board on my NAS dies, it will have a worthy successor
