4 Things to Know About Mixing RAM Brands
Mixing brands often works, but it is not guaranteed. Two sticks from different brands with the same specs—DDR type, speed, timings, and voltage—will probably run fine.
The real problem is the memory chips inside, not the brand label. Different brands may use chips from different manufacturers, and the CPU’s memory controller can struggle when timings do not match exactly, even if the specs look identical.
If you already have both sticks, test them. Run MemTest86 for a few hours or at least one full pass. If it passes, you are good. If it fails, do not waste time troubleshooting random crashes.
Matched kits are tested together for a reason. Buying a new kit costs less than dealing with intermittent blue screens for the next year.
