booted and stable, but can't get sata drive to work 3/5/2020 1:10:44 PM

Pros: -works with dual 200W CPUs, 768GB ECC, PCIe SSD RAID card, PCIe 10G ethernet card, and Titan RTX
-is stable with 1000W PSU (no PSU listed on AVL sheet), consumes 550W with full CPU load

Cons: -cannot get SATA drive to work on any of the 10 SATA ports. Tried diff cables for data (ones that shipped with the mobo) and power, drive checks out good in another box. M.2 drive works and so does the PCIe RAID card. Intel and ASmedia controllers are enabled. Running latest BIOS v6003
-BIOS update was a nightmare. ASUS update started and then box turned off instantaneously, no lights. Powercycled the PSU after waiting 5 minutes. Board would just cycle through booting, getting up to LED code 6d (I think). Ended up doing BIOS flashback, which took way longer than spec'ed. Would not boot until I power-cycled PSU again. Came up as v6003 finally, started process with v5701
-motherboard FAN info not available in Corsair LINK, temp sensors wrong (installed the chipset drivers). Not super important since I use a water-cooler for the CPUs.

-EEB formfactor requires drilling case for crucial mounting holes in Corsair 750D
-single USB2.0 header
-no built-in 10G

Overall Review: -Don't know how many of my issues are due to possibly a bad BIOS flash? I don't want to try reflashing right now as we are using the system (I have tried reloading defaults from the BIOS screen).
-I used 2933MHz ram and it reports as such in Task Manager, but CPU-z reports 2400MHz...
-specs not really clear regarding max RAM/NB freq

Actual performance exceeded my expectations

Dear Valued Customer,

I'm sorry to hear that you are having BIOS and SATA issues with this board. All ASUS products undergo intensive quality control, testing and inspections. What you've experienced was not intentional or representative of our brand. If you haven't already, please verify that your memory kit is on the QVL linked below. What frequency are you seeing in the BIOS for your memory? Regarding your SATA issue, I recommend upgrading the SATA drivers and potentially flashing the BIOS once more for stability. If you have any general or technical questions, please email me at cl-lane@asus.com and include case #N200318103 for reference.

Thank you for choosing ASUS!

Asus motherboards never let me down! 6/24/2019 10:46:47 AM

Pros: - Worked right out of the box
- Support up to 768GB of DDR4 ECC
- Good for multiple GPUs setup
- Works with H0 CPU stepping

Cons: - If only they have more built-in M.2 slots to take advantage of all the PCI lanes from 2 CPUs.
- Single CPU setup would be able to utilize only half of the memory/PCIE slots.
- EEB form factor so there could be some drilling works if you have a normal case.

Overall Review: I have own this board for a few months, running 24/7 and it has never let me down since day 1. I rarely write review but it seems there are some unfair reviews for this product so I decided to share mine. Currently I am running a 2x8173m, 384GB DDR4 ECC, 3xGPUs setup for machine learning and other stuff.

Initially, I did not purchased this board but the Supermicro MBD-X11SPA-TF-O (single CPU) brand new from Newegg, thinking Supermicro boards would be compatible with most of CPUs stepping including ES/QS. I actually own a pair of xeon 8173m CPUs with H0 stepping (not ES). The Supermicro board could not manage to boot a single time even with known working components - all it did was giving me a strange beep code that did not match any of the beep code that Supermicro has. I had to return it and replaced with this Asus board based on my previous perfectly positive experience with their products.

The result was perfect once again! The system booted up immediately with both CPUs and all 12x32GB DDR4 ECC recognized. Both CPUs and memory sticks were purchased used on other sites. The great thing about Asus board is that it shows boot codes that I can easily look up and make changes accordingly if needed, much easier than the high/low pitched long/short beeps of Supermicro. Both Windows Server and Linux were installed on this system and it has been running 24/7 without issue ever since.

There are a few minor drawbacks though.

Firstly, I owned a Corsair 540 Air and this board is slightly wider (but still fit in the case just fine) as well as it needs different set of holes to screw in. This is not a big deal - took me ~15 minutes to align the board and drill some holes on the case. You might not be able to have all the holes with this case since some would fall on the rubber part of the case.

Second drawback is that it only has 1 built-in M.2 slot. If you build a multi-GPU system, which is likely the case for using a dual CPU system, you would have no other slot for more M.2 SSD and has to use SATA SSD for additional storage or dual boot. It is quite a waste for 96 PCIE lanes from 2 CPUs.

Finally, you will need both CPUs to use all PCIE and RAM slots, but this is quite expected for dual CPU boards.

For the negative reviews about this board not working with ES/QS CPUs, this is not really Asus fault. Online sellers always show which boards they tested to work with their CPUs. It has been years that similar boards made by Asus, excluding server boards, are consumer grade and they only support retail or sometime QS CPUs (such as their X99 2011-v3 series). You should have known which board is compatible with your CPUs before buying it or buy compatible CPUs if you like this board...

To sum up, get this motherboard if you know it works with your components and if you do have 2 CPUs to fully utilize all features. This is a costly setup but I am very happy with Asus quality so far, especially when it comes to motherboards.

COMPATIBILITY NIGHTMARE. BUT IMPRESSIVE PAPERWEIGJHT - STAY AWAY if you are running engineering or quality samples.- 10/26/2018 3:14:33 AM

Pros: Compact layout
Plenty of fan headers
Potential for significant overclock for compatible CPUs

Cons: 6 month owner and this board has stilll not even posted for any of my scalable xeon CPUs.
For this kind of money, a board should WORK. NONE of my 3 different models of scalable xeon B0 CPUs even POST on this board, same CPUsL work like a charm on Supermicro X11 boards! So far, xeon gold 6149s, xeon platinum 8168s, and xeon platinum 8180s all do the same thing - run great on supermicro, but die at post code 66 on this ASUS board.

Returned the first C621E Sage when it would not even POST past 66 with ALL known-good compatible components (RAM, GPU, drives etc) that all work fine in several different Supermicro X11 motherboards. Naturally, I though the first board just had some sort of defect. But the replacement C621E board has exactly the same problem. After at least 50 contacts with many different ASUS tech reps for 5 months and flashing 2 BIOS updates, there is no progress to a solution.

Overall Review: Supermicro X11 boards runs everything, this board doesn't.

Even though my board has not even worked, I still give ASUS two stars is for consideration that the Mobo business is difficult and there are reports this board DOES work with $5,000+ production Xeon scalables. But I never expected to have a problem that the world's biggest motherboard producer could not solve. I have hung on to this board hoping that ASUS
would step up with a solution to run ES cpus. But no BIOS update has resolved the no-post problem yet.

I will update this review or delete it when ASUS can provide a board fix that allows me to run the same CPUs I already run
on Supermicro boards.

Works Great 10/19/2018 6:50:39 AM

Pros: Lots of Expansion
Lots of power
Lots of CPU and Memory

Cons: Takes 30 seconds to post
If using 1 CPU reading the instructions is a must. Motherboard had a predefined PCI and memory layout that you must follow.

Overall Review: so far our video editor is loving the computer we built with this.
