[SOLVED] Which ram speed?

[Devin082987]

If my system calls for 2133mhz memory, and has no way to speed it up in the bios, and none of the normal programs work for the overclocking of memory on my hp 17-X115DX, is there any reason I should buy something faster like 3200mhz? Wouldn't the 2133mhz have lower latency?

Hey there,

Sadly there is no point in getting faster ram, than what the mobo can do. I've an HP Omen, and similarly my speed is maxed at 2666mhz which corresponds with the capabilities of the CPU. It would be a waste to put anything faster in.


Although you could get ram @2133mhz with tighter CL timings, that will not give a huge boost in performance or anything. Some programs would respond slightly better, but in general there would be no perceivable difference. Getting more ram, is often the most you can do with laptops. But for you, you would need to get 2 so-dimms with 8gb each to increase your total ram. You could just get another single 8gb stick, and add it to one of the 4gb dimms for a total of 12gb. But, you may as well just get two new 8gb sticks, and sell your current ram to offset the cost.

Yes. Many laptops will dynamically increase memory speed if the RAM and CPU allow it.

I bought an HP 14-dq1039wm early last year. It came with 2666MHz RAM with no way to adjust in BIOS, however, when I upgraded the RAM to 3200MHz the RAM started dynamically boosting all the way to 3200MHz at times.

Of course, YMMV. Your laptop may not boost the memory up to its maximum.

I guess this shows that it depends on each individual laptop.
My CPU (i5-1035G7) can run the memory at 3200MHz.

OP, what specific CPU do you have in the HP?

It's funny, because it actually came with a single 8gb stick, which I've never seen a computer come with a single stick. Without opening it up, I had ordered what I thought was 2x8gb but when I got it, it was actually 1x16gb at 3200mhz, I was planning on returning it for the 2x8gb because I've heard, arguably, that dual channel increases speed, but I wasn thinking that since I can't overclock it, I may as well just buy a matching 8gb and call it a day.

I bought a single 16gb 3200mhz by mistake instead of 2x8gb, and was going to return it for the 2x8. Right now in cpu-z the dram frequency is 1064, but the Uncore frequency is 3291, so what exactly does that mean?

What is your specific CPU model?
Once I made sure that the 1x8GB is removable/replaceable and that I had 2 slots available, I would buy 2x8GB at the max MHz RAM speed supported by the CPU.

Dual channel (2 x Dimms) can give anywhere from 5-15% increase in performance (task dependant) defo worth the free boost. That's separate from the speed of the ram.
