RAM - ECC and non-ECC un-buffered DIMM

[HBSound]

So, I am going back and forth about these two RAM brands/manufacturers. I aim to have 96GB of RAM, with ECC and non-ECC un-buffered DIMM. Right now, I am going back and forth about the two. I currently use Kingston in my workstation and have had no issues. I have only seen NemixRam via websites etc., but I have never used it. I use my current workstation for CAD, BIM, 3D, and Rendering. So I am shotting for stability.

Kingston Offering - KSM56E46BD8KM-48HM ($550.00)
Nemix Offer - MD44800-4828K2-MAG ($300.00)

My motherboard of choice is the ROG STRIX X870-I GAMING WIFI.

Is the Nemix brand of RAM worth considering? Or would you stick with Kingston?

I can't really speak to DDR5 with Nemix RAM but my DDR4 system with Nemix was not stable with 4 sticks (128GB) at idle so my confidence level with them isn't as good as let's say genuine Crucial/Micron but other than that they seemed to work and I saved some money at the time. In retrospect I ended up buying Crucial/Micron later to solve the problem and would have been better served just buying that option up front for the extra $100 or so premium at the time. I don't know why but there is a reason Nemix is cheaper and you pay for what you get.

Thank you. I was considering biting the bullet and getting the Kingston RAM.
That is the route I will take.
Thank you for sharing!

In my current system I'm running 64GB Crucial/Micron DDR5-5600 MTC20C2085S1EC56BD1 but it's still pretty expensive compared to consumer RAM. They seem to overclock well to DDR5-6200 for a nothing burger performance boost but I haven't tried reducing the timings yet to see how well it responds for curiosity sake.

One thing I did notice is AM5 automatically tweaked the timings for me from CL46 to CL44. I'm not sure if that's normal or not but something to look out for after you install your RAM. By default after installing it the UEFI/BIOS wanted to run it DDR5-5200 and gave me an option to select the speed from the modules profile.

I would be interested to see how your Zen Timings look after you install it to compare.

"ECC and non-ECC un-buffered DIMM."

I assume you mean "ECC or Non-ECC"? The STRIX X870-I GAMING WIFI can support both ECC RAM modules and non-ECC RAM modules, but there's no such thing as "an ECC and non-ECC un-buffered DIMM" because it's a contradiction (a DIMM is either ECC or not. It can't somehow be both ECC and Non-ECC at the same time), and you can't mix ECC and Non-ECC DIMMs in the same PC.

The Kingston RAM is ECC. The Nemix RAM is Non-ECC (hence why it's much cheaper). If stability is your top priority, the Nemix RAM would not be suitable.

I would be wary of using ECC RAM in an ASUS X870 motherboard.

While ECC RAM is compatible with ASUS X870/X870E motherboards, some users have found that the ECC functionality is disabled on some models. It may be possible to enable full ECC support in the motherboard's BIOS settings, or by updating the BIOS version, but if you cannot get the ECC error correction to work, there would be no reason to use ECC RAM, as it would be a waste of money compared to normal non-ECC DDR5 RAM.

(I assume it's ok to post this link for evidentiary/explanatory purposes. If not, please let me know, mods)

If you want ECC RAM, I would personally opt for a different AM5 motherboard which is confirmed to have working ECC functionality. There are a few different models which people have reported having working error correction on reddit and other sites, but I couldn't find any talking about the STRIX X870-I GAMING WIFI. If anyone with an STRIX X870-I GAMING WIFI motherboard has been able to get full/multi-bit/side-band RAM error correction working, it would be very useful to get confirmation. It also might be possible to ask an ASUS rep to confirm whether full ECC error correction can be enabled on this board, and whether you might need a specific BIOS version, though some reps don't understand the difference between the different levels of ECC support, so might give you a misleading answer. On-die ECC is included on all DDR5 modules (even "non-ECC" DDR5 has on-die ECC) and is supported on all DDR5 motherboards, but full ECC support is only available on specific motherboards with specific BIOS versions. A motherboard having ECC RAM module compatibility listed on the manufacturer's website means that it is able to run with ECC modules installed, but doesn't necessarily mean that full ECC is supported.
