I believe the aftermarket cooler you are using is a lot bigger than the AMD Spectre coolers right? (I'm just going off looks here). But yeah, you have a great point. With so much variation in ram... Some being small and sleek and some having massive heatsinks, so many different CPU sockets and sizes, and so many different purpose coolers.... We definitely need some more info!
RE: Since when did CPU coolers get so (D)RAM picky?
