Looking for assistance with DDR4 2666 and DDR4 1866 motherboards?
Hello everyone. I’m trying to look this up online but can’t find a precise solution. I own a MiniPC running an HP T630 with an AMD GX420GI processor. It supports DDR4 1866MHz SODIMM, and the max RAM capacity is said to be around 32GB. I don’t have a 16GB module at 1866MHz, so I’m keeping it safe. The main question is whether my 2666MHz RAM can actually handle that speed. There’s no official limit mentioned for maximum speeds, so I’m not sure if there’s a lower bound either. Sorry if my English isn’t clear.
You're welcome. It's still fine to use a 2666MHz or 3200MHz RAM with an 1866MHz motherboard.
The advertised RAM performance refers to the highest speed it can achieve. It must match the motherboard's specifications and JEDEC standards. While you might receive the full speed your RAM claims, the actual performance will depend on the motherboard's capabilities. For cost efficiency, it's better to choose a RAM that is just above the supported speed if an exact match isn't available. For example, if you have a 2666 MHz RAM, opting for a slightly higher speed like 2686 MHz can be more practical.
Listing the specifications as DDR4, up to 1866 MT/s: https://support.hp.com/in-en/document/c05240287. It should support SO-DIMM sticks at 2133/2400/2666 MHz without issues. The real question is how much performance boost this would bring with the processor—still uncertain.
From what I understand, the unusual RAM speed depends mainly on the CPU's capability. Therefore, opting for 2133 or 2400 MHz makes sense. However, overall hardware performance is unlikely to noticeably improve.
Thanks for your assistance. Concerning cost-effectiveness, in my country the price remains consistent regardless of the 2400, 2666, 2933 or 3200 Mhz RAM—only capacity affects the cost. For example, a 16GB DDR4 2400 costs roughly the same as a 16GB DDR4 3200, around $100. I think I’ve grasped the performance differences a bit better. Just wish I can avoid BSOD problems.
