It had a pretty old BIOS, so I updated it to be ready for Broadwell if needed.
I had been giving the advice that it's always good to buy memory from the QVL if possible, but had finally been convinced by the repeated rebuttals of respected members here that such attention to detail is not required for consumer level boards. But wouldn't you know, this Asus was finicky about what memory it liked, crashing repeatedly until I swapped in the good stuff out of my gaming rig.
It's important to keep in mind the expected costs of production for boards, which includes the marketing and spec-testing. All manufacturers, if they have half a brain, maintain a testing lab. The QVL list is only the list of RAM that they've tested. Obviously, they cannot test all makes and models.
Working with just the QVL list, you can print it and make a note of the models for different RAM brands of whatever lower or higher RAM speed-spec the manufacturer chose to test. If the speed you want is not in the QVL list, but the model is basically the same, you can extrapolate a fairly good guess as to whether the RAM you have in mind will work. So, for instance, if you wanted G.SKILL "GBRL" DDr3-1600s, but the QVL listed DDR3-1333 GBRL's, you could pretty safely say the 1600's would work if the board offered up a 1600 (OC) spec. This should apply to the more recent high-performance RAM that added value for Z77 and later chipsets.
You're other option is to find the RAM-maker's web-site after making note of your motherboard's model-code, and use their configurator link to find their models and speeds which work with that motherboard.
Short of doing that, you can also do some general forum searches and reseller-site searches for comments or customer-reviews for either the board or the RAM, and see if you find a confirmed intersection of compatibility.
