Want to Buy RAM - Need Help

[LeMao]

This is the current ram in my PC - https://www.walmart.com/ip/Kingston-8GB-DDR4-1Rx8-PC4-17000-2133MHz-ASU21D4U5S8MB-8-Desktop-RAM-Memory-Refurbished/565190161

"Currently only have Kingston 8gb DDR4 RAM"

I was originally going for another 8gb same stick for 16GB, but I found a different stick for a cheaper price of $30. https://www.kingston.com/us/memory/search?partId=KVR24N17S8%2F8

I was wondering if this is going to have any problems with the current RAM stick or have any downsides of having a different stick but from the same manufacturer.

Or maybe if you guys can find a better RAM stick and recommend it to me (prefer 2x8)

Thanks!

Bad idea, because when mixing modules, it always goes with the lowest frequency rating and highest latency out of all modules. So mixing a 2133 CL15 module with a 2400 CL17 module results in 2133 CL17 settings, which would lower RAM performance as the access speed is lowered. You always want lower CAS latency, or CL, is the lower the latency, the faster the RAM access speed. Higher speeds can solve some of it if the latency isn't too much higher, but the fact that your memory will default to 2133 unless you overclock your current module means that you would be putting yourself at a disadvantage, and those modules are both cheap and lack any sort of heat spreaders. It's more worthwhile to spend the extra 30.

Get the same module you already have.

I see, ill i get the same ram. One more question, do you have a recommendation of a good 2x8 RAM sticks around the same price point? I was wondering if my current ram is old or inferior to other ram sticks

You can get 16GB (2x8G) Crucial Ballistix Sport LT 2400 MHz CL16 RAM from Amazon for 60$ US: https://www.amazon.com/dp/B06XJ5RTBY/?tag=pcpapi-20

If you're running a Ryzen build though, you need a DDR4-3000 CL15~16 kit to bring out most of the potential without blowing up your wallet. Best case scenario for 1st and 2nd gen Ryzen is DDR4-3200 CL14, and the best for 3rd gen appears to be 3600 CL16 unless you make some major tweaks to the infinity fabric.

Yeah, the Crucial kit I linked will work. Intel has nearly impeccable memory support.

Would 2400 Mhz be ok for my rig?

Yes, I said it's fine, and the 6400 doesn't really benefit much from more than 2400, and it's within your price range. The latency is better as well.

Thxs for your help!

Intel 6th gen cpus, unless using z170 or z270 board can only do 2133 anyways.

I would just buy cheap Kingston 2133 to match the other. No point buying really good ram when it's a 6400 cpu

2400 works but it doesn't "support" more than 2133. It won't make a difference.

[Bad 💀 Motha]

Yes 2400 would work, just forced to run at 2133

If the motherboard doesn't support 2400, yeah.

[Bad 💀 Motha]

Unless it is a Z170 or Z270 board, 2400 xmp profile would not work. Those lower chipsets will not support above 2133 when using 6th gen cpu.

But given how rare 2133 ram has become, he's fine to just get a stick of cheap 2400 amd have it run at 2133

My motherboard is a Intell h110 chipset idk if that helps, either way I'm fine sticking with 2133 ram, just that 2x8 2400mhz looks like a great deal with only $60 for two.
