DDR4-3200 is already fairly slow for a new system -- DDR4-3600 f.e. aligns with the 1800 MHz Fabric Clock in Ryzen 3 and makes a not insubstantial difference in performance, and (non-ECC-wise) is not expensive. I have a feeling the cost is not just a money-wise 5-10%.

Amazon currently lists the 32GB Nemix DDR4-2666 UDIMM for $169.99 while a non-ECC UDIMM is $129.99. So you're right, at $40 it is closer to a 30% premium right now. But that one time cost of $40 per DIMM is worth it if it even saves me 10-15 minutes of time debugging. And I'm willing to pay that small cost adder on every new machine I get, because I have the battle scars that have pro It's not like I'm dealing with hundreds of systems, this is across maybe 2 or 3 dozen machines over the past 30 years.ven it's a worthwhile tradeoff. The battle scars are as follows: - The 2MB expansion card on my Amiga 500 turned out to have a couple of bad bits, and because I was a green techie back then, I just attributed it to general software instability. Years later a RAM test showed there was a problem. Sadly there were no memory test utilities shipped with Amigas back then. - My first 486 system had a bad bank in the SRAM on the motherboard. Took years to figure out as it only really hit when heavy DMA occurred from a VLB SCSI card while the CPU was heavily loaded. Swapped the SRAM out and it was stable for a few more years of service. - One of my K6 systems had a DIMM go bad. At least it failed badly enough that the system couldn't boot. - I've had an Intel Xeon in a colocated server start throwing ECC errors in the L3 cache. Replaced and RMAed the CPU before it caused an outage. - One system started throwing ECC errors because the power supply was marginal. Now, please, show me how the extra cost of ECC is worthless to you when things like this happen in the Real World. Is your time spent debugging hardware failures really not worth the cost of ECC?
