Good to know. All ram should be same specs, works best, especially if doing any kinda dual channel. However, If you tried different configs of the ram and test w/ memT  that can tell you better what is going on. Depending on setup options you don't always have control in bios over timing/voltage tweaks so you get stuck w/ defaults. Certain ram just doesn't do well w/ certain mb's. Better quality ram in gen is more compatible. Dual channel kits can actually be headache savers.

No need to think outside the box....
