ECC Errors that were corrected during memtest86. Should I be worried?

Hi! I ran MemTest86 v11.00 and during first pass I got 2 ECC Errors, since then no errors in 35 hours

I should mention that my memory was very hot during first pass (I saw 72 C at some point), then I speed up CPU fan (only fan I can control) and temps were 50-60 C on all other passes

SUPERMICRO X9DRL-iF
Intel Xeon E5-2667v2 (1 cpu in two-socket MB)
2×32GB Samsung m386b4g70dm0-cma3 (ECC LRDIMM)
PSU Corsair TX650M (Only one 8-pin EPS connector is connected)

What should I do? Should I be worried or should I just ignore it?

If you have solved the heat issue and no more ECC errors… then its probably safe.

If you get more ECC errors… then ignore my advice.

From what I remember, your screen means that 2 errors were detected but corrected, infact Total errors are 0 at every step.
From what I see you don’t have the temp of RAM available (N/A), the value on top left Is the CPU temp.
IMHO, as already said, with other 35h of test without errors, and with only 2 occurs and corrected, you should be safe

I’ve been monitoring the memory temperature via IPMI. I did not confuse it with the CPU temperature

Thanks!

I think I’ll run another full memtest86 just in case, but this time with normal temperatures. If there are no errors, then I will assume that everything is fine now

I have to agree, if you keep the temps under control then all should be good.

With that said… Test time: If you drop the RAM speed from 1866MT/s down to 1600MT/s, and without your extra cooling, I suspect the RAM will not get nearly as hot and the testing will pass every time. Compare the temps for the test runs, see if this helps.

Why do this test? Well what if the fan fails? A cooler system is generally a more stable system.

So I ran another full MemTest86 v11.00 with RAM being at 50-60°C and memory speed forced down to 1600MT/s. After 53 hours everything is fine, no errors at all. I guess it actually was a temperature problem with my first test

Thanks everyone for help!

Glad that advice worked out for you.

But you know, I can’t leave it just there, I have another question…
What case is this system mounted too?
How is the airflow through the case and is it proper?

Generally I see a lot (my perspective) of people cramming a lot into a small space and never thinking twice about proper airflow. Having a way to remove the heat created is critical.

While you do not need to answer my questions, just think about it. If you feel you have proper airflow and want further advice, strike up a MESSAGE with me and provide some detailed photos of the computer. I would need the outside photos, and absolutely the inside photos which provide me the locations of the fans (and size of the fans), the drives, top fans, bottom fans, does the power supply have a fan or is it fanless.

My most recent system that I built was honestly, a poor case choice, but damn it looks nice. It is an Asus AP201 and it just looks great. And I designed an all NVMe system, no hard drives at all so cooling was not really a factor in this build, until it was. The addition of a single fan solved the issue. The system was functional, I just didn’t like the temps on the NVMe drives, too hot for my liking, but well within specifications, so if I lost the fan, the system is still stable. With all the holes in this case, it is impossible to get a well designed airflow through it, so it is only useful for low heat systems.

Anyway, if you fall into this category of airflow, just toss me some photos and I will provide some good advice that may allow you to run the RAM at full speed and keep the rest of your system cooler.
