Mixing RAM? help pls

[PentestingFTW]

So i have this weird issue when taking ram out of pc, whenever i take it out, the ram sticks dont work for either a few days, weeks, or ever again, same with taking it out and putting it in same pc or different pc, idk its weird, something to do with cmos maybe. anyways i have an old 16gb kit of ripjaws V 3600mhz, and i was wondering if i could mix it with my other 2 sticks of 2x16(32gb) of Corsair LPX 2600mhz, i know if i can it would match faster clock speeds with the slower but im fine with that, and does anyone know about the problem with ram?

My inexperienced guess would be dirty contacts/slot. Do you have electronic cleaner?
Also, when the ram works, have you run prime95 to ensure that the sticks are still good?

what CPU are you using?

it would run at 2600mhz, but I have no idea about your other issue. Maybe ur cursed?

I'd guess some issue with the motherboard, maybe a setting in BIOS. If the board is a couple of years old, try replacing the CMOS battery. Mixing ram should work just fine but you may need to run without XMP. If you need that 2600 speed, you may end up setting clocks manually.

well the thing is its happened with many pc's on maybe different motherboards, different chipsets, different sockets, everything, even new mobos

Then maybe it's the memory, could be a loose solder joint. I've had memory in the past that was picky about the right voltage. It would work great in older systems that had no dynamic vcore or boost and caused a lot of head scratching on newer boards. I've ended up replacing the memory and the issue has since gone but I still have the memory and I can tell you that it does drive my brother crazy from time to time.
