I applied Stabilant-22 to all the DIMM slots, PCIe slots, and CPU sockets in both of these mobos when they were both new (late-2014).
Maybe overkill back then, and in my fairly exhaustive testing it didn't improve or diminish any performances in any way. But now, years later, it sure makes these slots easier to clean - a few blasts of compressed air effortlessly scrubbed them clean-as-new within seconds, no more dealing with little swabs and toothpicks, lol.
Alas, the stuff otherwise seems to have had little or no real effect on long-term reliability. Too bad I didn't leave one board untreated for comparison purposes.
