If you actually needed ECC, you wouldn't hesitate for a second, and it would be painless.
It's a shame that the infinity fabric is tied to the memory speed.
spending $750 on this slower ecc memory kinda hurts more than it should.

16 cores @ $850. BAM. rumor though, but still BAM!
Being 4 DIMMs this sould be fine! But you'll miss out on the dual rank performance gains, which are like 200-500 MHz higher RAM speed for several games and apps.

Pretty decent video on Intel's upcoming x299 platform.
I think their 14-18 core chips have been delayed to 2018, so it seems it was just a knee jerk reaction to AMD threadripper announcement. Looks like AMD caught them with their pants down.

All those OC DIMMs are rated at JEDEC 2133 speeds or so, but come with an pretested headroom (the XMP setting). Why shouldn't ECC RAM have some headroom too, just not being marketed this way?

good point. I'm just trying to do unusual things for odd reasons I guess.
But the same applies to anyone with 64GB of mem on ryzen too, not just ecc, There is a tradeoff. Maybe i'm just feeling left out of the overclocking fun you other guys are having
Maybe I should get a fast 2x8 kit for this system and put the ecc stuff in a threadripper system.
I would really love to upgrade my back office host to Ryzen, but with mainboards only supporting 6 sata ports and no raid 5, looks like i will have to stay with Intel
but I think Thread Ripper, if it support ECC would be great
All Ryzen cpu's has ECC capabilities. It's up to mobo makers to implement. There are a few that does and persons have verified it's working.
Here you go. Ryzen and ECC.
This lack of settings severely hampers the overall ECC functionality, since a big part of it is that the motherboard should be able to log errors. Right now, no such logging capability exists.
...
If it does not, the hardware might be silently correcting single-bit errors and even detecting 'catastrophic' two-bit errors, but you will never know about it since there will be no log.
...
The first command (wmic memphysical get memoryerrorcorrection) essentially queries Windows as to whether it detects any form of memory error-correcting code functionality. Regrettably, 3 signifies "none". The other options could have been 2 (unknown), 4 (parity), 5 (single-bit ECC), or 6 (multi-bit ECC).
...
If the TotalWidth value is larger than the DataWidth value then ECC is enabled. Ideally, we would have liked to see 72 for the TotalWidth instead of 64, since that would have indicated that the OS detects a 72-bit memory bus width, which as we discussed in the first page is the norm for ECC memory. Once again, no such luck.
...
Just for the hell of it, we loaded up Windows Server 2016 in the slight hope that an operating system that was designed to be used on exclusively ECC-enabled hardware might produce different results. We tried all of the same Windows commands, as well as all the same applications, and they all reported the same information as Windows 10 Pro.
...
Based on just the above information, it would not be prudent to say that ECC is enabled on this platform
....
HOWEVER, things are not quite perfect. On that last line you will notice "1 UE". That is an uncorrected error (UE), otherwise known as a two-bit error or a hard error. Two-bit errors cannot be corrected by ECC memory. What is supposed to happen when they occur is that they should be detected, logged and ideally the system should be immediately halted. These are considered fatal errors and they can easily cause data corruption if the system is not quickly halted and/or rebooted. Regrettably, only 2 of the 3 steps happened. The hard error was detected and it was logged, but the system kept running. The only reason that it's the last line on that image is because we immediately took a screenshot just in case the system would halt, but that never happened.
....
In conclusion, what is currently available on the AM4 platform is an incomplete implementation of ECC.
That's not all that true. You can do 64GB at 3200MHz and you have better perf with dual rank kits than single rank.
2x16GB or 4x16GB should be in the same ballpark, perf wise with 2x8GB at 3600 -if you can get 3600 stable for 24/7 use.
The first link i could recall for some tests for single rank vs dual rank( some other german site and Hardware FR did some tests too a few months back) https://www.golem.de/news/ram-overc...-von-ddr4-3200-und-dual-rank-1704-127262.html
The perf gains do diminish at high memory clocks so even with 2x8GB you might be better off at 3200 and tight timings.
If you still use raid 5 you are doing life wrong.... Seriously raid6/z2 as minimum.I would really love to upgrade my back office host to Ryzen, but with mainboards only supporting 6 sata ports and no raid 5, looks like i will have to stay with Intel
Does one of the tachis not have 10 SATA ports?
Here:
http://www.asrock.com/mb/AMD/X370 Taichi/
edit: Ah, ok, 8 SATA which support RAID 0, 1 or 10. No RAID5.
