ramMixing ram?
I have an 8GB 3200Mhz CL16 RAM stick from HyperX in my older Fury model. I need more for work when many apps run at once, but I’ve learned that this type isn’t available locally anymore. The nearest option is a newer HyperX Beast, which matches the specs, though I’m unsure if it will fit properly.
You can always advice against mixing RAM, especially for high-end OC kits, but I have never, ever had problems with mixing RAM, with different speeds and timings. If you enable XMP or DOCP, the slowest profile will be used (from the slowest RAM). I'd say you could without worry buy another stick but it's just that there is the risk of the two sticks not working with each other. That is why RAM kits are sold with 2 sticks or 4 sticks - these RAM kits (sticks) are tested to work with each other.
The situation is clear... Kits with 2x8 or 4x8 dimensions have been verified to function together, whereas DIMMs from separate kits or single units haven't. They might perform well together even at XMP, but if they fail, warranty coverage may be lost. They should run smoothly at JDEC speeds, though I can't guarantee it without knowing the CPU's memory controller. Kingston spun off its HyperX line to HP (probably HP), and what was once HyperX is now called Fury. I swapped my 2x8 HyperX setup for a 2x16 Fury Beast kit. Performance remains consistent, but timing appears similar. I suspect the new chips are Samsung-grade (lower quality) compared to my previous units, which were likely SK Hynix or Micron (also lower grade). Whether they'll work together is uncertain—probably yes, possibly at XMP without adjustments, but it depends. (I need to manually configure some timings for my kits to reach XMP without issues, since my motherboard doesn’t auto-set them.)
When considering overclocking, mixing and matching components isn't ideal unless you're certain. If not, performance will be only slightly reduced because both systems will operate at slower speeds. You might still consider selling your RAM to avoid compatibility issues that could lead to failure.
The motherboard isn’t concerned with the specific brand or model of the RAM. What’s important is that your clock speeds align with the slower memory type.
Focus on the rank—single or dual—and ensure it aligns. Next, verify memory controllers and adjust if feasible; don’t worry about the end of the world. Finally, confirm the second stick can meet or surpass all timings at your current stick’s rated speed. If you hit all three, key works is a safe sign.
Not sure if ranking matters these days... Back then, older chipsets like MVP3 caused big headaches. Now it seems like a minor concern unless your board is outdated. I've been through a while without memory issues or motherboard problems, so I thought ranking wasn't the real issue. Memory control has shifted to the CPU side now, and neither AMD nor Intel seem to have major rank problems.
Ranking top motherboards still sets the upper limit for memory speeds on that board. In pairs and isolation setups it usually doesn’t create problems. Using a dual channel with mismatched ranks can disable "Rank Interleaving." Not too bad, but the most concerning issue before total failure.
