I9 13900K supports memory speeds of up to 4 slots simultaneously.
Hey everyone, I'm planning to build an i9 13900k with 64 GB DDR5 RAM at 5600 MHz. I'm curious about whether a 2x32 or 4x16 configuration affects performance. I'm concerned that using all four slots might slightly reduce the speed compared to just one slot. The Corsair Vengeance RGB 2x32 kit is tough to find, but I could opt for two pairs of 2x16.
It’s rated at 5600MHz with XMP support for that frequency, so it should handle the signal across all four slots. If not, you might ease the timing or boost the voltage to get it working properly. A 2x32GB setup would likely be more dependable, though 64GB is a solid future-proof choice right now. Four 16GB modules would also provide a good buffer for at least another six to eight years of use.
I'm not sure about the 13900k or DDR5 specs, but generally you should aim to purchase everything together rather than separate parts to prevent problems. Two 2x16 modules won't give you the full 64GB and might cause compatibility issues. Some users manage well, while others face significant challenges achieving speeds beyond the standard.
The device is an Asus PRIME z790-A Wi-Fi module. It supports DDR5 up to 7200 MHz and allows overclocking.
If my understanding is right, any different sticks coming out of separate boxes might lead to problems. The older the standard, the higher the risk, and DDR5 is currently the latest release. You might manage fine, but using two Corsair sets bought three years apart for many years worked well; however, you could end up with slower performance or even stock configurations, particularly with more sticks. The motherboard handles the memory controller, not the CPU, so it depends on your CPU's preferences. I'm not trying to scare you, just want you to know it's generally not recommended.
That means nothing. They can still have different memory ICs on them, and which is what actually dictates memory compatibility. If you buy them at the same time, they're pretty likely to be identical, but it's still not guaranteed. If getting a 2x32GB kit is an option, get that instead, 4x16GB does work at 5600 with identical kits (there are screen shots of it working at 6600, so 5600 should be no problem) but there's enough risk with 4x16GB unless you're buying rather high end kits that I can't recommend it.
I'm also planning to purchase it together. The whole system will need a lot of power—probably around 4000 euros or more. That means I won't be skimping on memory. The issue is that everything has to be white. The entire setup will be white. I can locate the 4x16 kit with the exact specifications I need, but only in black. I suppose I just have to keep searching. Appreciate the response!
