I'd started to get bouts of instability. When I do some basic troubleshooting and quickly became appearent that it an issue with the memory. . I was able to rule on the memory and slots as playing around with units and slot didn't change this. The motherboard is able to drive one stick without any issues though. This leads to be believe that my current motherboard longer is able to drive my current memory at 3600Mhz at dual-channel(Interweaving) without memtest errors. I was forced to take it down a notch. My motherboard is going to be three years old soon and I was wondering if DIMM slot degradation was a normal thing for motherboards when it is trying to drive DIMMs at non-JEDEC spec.

It's the memory controller on your CPU, not the motherboard.

Hard to say for sure, unless I throw in another set of good DIMMs that work elsewhere with similar clockspeed and timings and issue persists and later throw the CPU in question on the another motherboard and problem migrates with it.

Considering there's essentially zero active components on the board between the slots and the pins...it's the CPU.

I wouldn't rule out thermal and electrical stresses taking their total on the tracings. 9700K does throw a ton of heat in that area of the motherboard when loaded. These "gayming" motherboards aren't exactly built with quality and no expense was spare in mind.

You can not rule it out if you wish. Bumping up the IMC voltage will likely bring it back to stability.

The only catch is that IMC is very finicky with Intel chips when overvolting. They tend to burn up. I would rather deal with taking a hit on dialing the memory back then take that possible risk. It would only be a problem if IMC cannot handle JEDEC-spec speeds and timings.

Running XMP already overvolts the IMC.
