GN that did an alaysis on this - ram kits on the QVL often have subtimings set that are optimized and sometimes not exposed in the bios - meaning they will perform better because there are buried subtimings optimized for the kits. It was fairly amazing how much difference it made - 3200mhz kits that were on the QVL were performing on par with kits that were rated at 3866 but not on the list.
From the article:
"You'll notice going forward that the GeIL kit is always among the worst on the bench, but note one thing here: After refilming this twice for the Vengeance LPX kit retests, we also re-tested the GeIL kit for validation. It validated perfectly on the Gigabyte board, meaning that the GeIL kit remained in exactly the same spot in the charts. We then tested it on the MSI board, and found that MSI's board auto-configured better timings than Gigabyte for this GeIL memory to significantly improve performance. "
It was on the QVL for the MSI board but not the gigabyte board. I know a lot of boards for these have all of the subtimings exposed, but if you're more of a set docp and forget it, I'd stick to the QVL, especially for higher priced kits as otherwise you might not be getting what you paid for.
That is interesting. I never knew this. In my entire almost 30 years of building PC's, I've never even looked at the QVL.
I figured it for a "small list of RAM they have actually tested, but in general RAM is RAM." type of thing.
Oh well. I doubt the RAM I bought is on the QVL, but hopefully it will do OK.
