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.

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.

As long as it's stable and doesn't cause errors or crashes due to b-die not liking the temps that high it's fine.

Looks to be a lot on there that is not tightened up.
If you follow a guide like the one in my sig first you can then tighten up tRFC and raise tREFI if desired to get better aida scores

Hi,

Been a while since ran Memtest but got Memtest HCL with Memtest Launcher and noticed a couple things not sure about:

1. Auto selects 2 instances at 1024 Ram to test (512 per instance)
2. Gives a message that PID {number} is using 512 shared memory and 512 private memory

Anyone notice that as well?

Help please.

Thanks

That guide has been printed by me and saved in my favorites! The guy you quoted is running my memory but only two of them I think anyway.. This is what I'm running right now and still working on tweaking at the moment.
