Compatibility of stored data across devices
Compatibility of stored data across devices
I own the DOMINATOR® PLATINUM RGB 32GB (2x16GB) DDR5 DRAM 5600MT/s CL36 Memory Kit. I’m considering adding two more sticks for a total of 64GB. Would this model fit? On the website, it shows "Memory socket support" 1 and 2, missing 4. I’m wondering if that means it should work, or if the lack of testing by Gigabyte is a red flag. Thanks!
A lot of memory controllers for DDR5 can't handle running 4 sticks at full XMP/EXPO speeds. What CPU do you have? If it's an AMD 7000 or 9000 series CPU, there is a reasonable chance that 4 sticks will not be able to run at DDR5-5600 speed, and will need to be downclocked to work together. With Intel, your odds are better, but it's still not guaranteed.
Your device is compatible with the recommended accessories, so those should work fine.
You can combine all four sticks for maximum capacity, but using XMP isn't assured. The 12900K only supports DDR5-4800, so you might need to slow down the memory to match that speed. In practice, you could even go slower than 4800 MHz. While it's possible if you enable XMP, it's not a certainty.
It functions physically on the board in a compatible way. Most 12th generation CPUs support DDR5-6000 on dual sticks, making success likely. I’m confident purchasing such a kit. However, there’s no definitive assurance that any unsupported motherboard will still work perfectly. Only someone with identical hardware can confirm it. At most, a user with the same board, processor, and kit can share their experience, which remains just personal anecdote. The QVL support section on the motherboard is the official reference, though I’ve often trusted community advice about RAM compatibility in practice.
