I found a couple of old MBs I didn't even remember I had, one for Core 8 series and one for Core 9 series. The 9 series works just fine. The 8 series beeps for memory, I tried several working DDR4 ram sticks but can't bring it up to boot. What can I use to clean the ram slots? Isopropyl alcohol doesn't seem to work. Someone suggested WD40, but I think that would make it worse.
Any ideas?
