translated: it is high for memory, but not critical. Errors may occur. Make blowing better in the case and preferably install a memory blower. All the heat comes from the video card.

kamyk155 Simply question about temperatures of B-die memory - today I saw 55*C on one of my memory sticks.
I think it is too hot. 4000MHz 18-18-18 with 1,41V now.
I put temperature sensors inside the radiators of three of my four memory sticks.
PS this temperature was only in Battlefield V - in benchmarks and other programs I didn't saw that high temperatures.

Even if the weather is not that much wet here in Switzerland (even not cold at all this year but this is an other story...) I suspect a very thin layer of oxidation appeared on the memory stick contacts that made my previously stable config a bit unstable.

Should you have this kind of experience (or also possibly to improve you memory OC!) try this very easy trick.

Note the very same applies to GPU/PCI (on the GPU side) and CPU/MB contacts (on the CPU side of course!).

Give a try and report back.
this is not unusual.

Could depend on what windows is doing in the background.
tRFC seems plenty low at 280.

Usually they all run at similar speeds. Once I noticed one running a bit slower than the others. Now I have like half of them running much faster than the others.

I even used ISLC to clear my standby list before running the memtest and I’m still seeing similar behavior.

I have an all core overclock of 5.0, so I’m confounded why some instances are running slower than others.
Probably the page file. I used to run 1150 mb per instance on my 12 threads (8700k w/ 16gb) and in hwinfo I'd get a max page file usage of 2.5-3% and several of my instances would fall behind the others by 100-200%. Now I run 1000 mb per instance and at most I'll get 0.3-0.5% page file usage and my instance percentages stay much closer together. As I understand it, even if you don't test so close to your max amount of ram, it'll still all get tested eventually.

If you are looking for gaming performance, focus on improving Latency. Actually, look to improve system latency which you can monitor with Latency Monitor.
Ah, I kind of see where you’re going.

I had XMP enabled and was able to get stable with setting manual 1.35 vdimm with 280 tRFC. Tried to adjust to 260 tRFC but it kept on booting with 280.

Disabled XMP and set manual frequency, primaries, VCCIO, VCCSA, vdimm, and training voltage and it booted with my manually set 260 tRFC. Running memtest HCI right now.

Does XMP enabled mess with the stability of manual memory overclocks? I’m not entirely sure why it refuses to acknowledge certain manually input settings.
