T470 RAM upgrade

Hello,

 

I would like to upgrade my stock 1x8GB 2400 MHz module to 2x16GB.

There are two options I am considering:

 

1. Kingston 32GB DDR4-2400MHz SODIMM CL14 HyperX Impact Black Series (2x16GB)

2. Crucial Ballistix Sport LT 32GB Kit (2 x 16GB) DDR4-2400 SODIMM

 

I would like to go for the Kingston because of lower CL, but it is not listed on Kingston website as compatible with T470 - i can't see why. Could there be any problem with that memory in T470?

The second one is listed as compatible on Crucial website.

 

Thanks for any help.

Re: T470 RAM upgrade

I have never used either of those modules, but I would GUESS that they both will work.  I would be surprised if you could ever notice the difference between CL-14 and CL-16 unless you were running a full memory test with a stopwatch. 16GB DDR4 modules are expensive, so I would always suggest you buy them from somewhere that accepts returns for compatibility,

The supported sticks for the T470 is 2400MHz CL15 so if you buy a CL14 it 'll "downclock" to CL 15.
So stick with the CL16 insted.

Hi, I'm in a similar situation, but want to know if this applies also to the frequency. I mean, I can install a 2666MHz and guess the system will automatically downclock it to run at max laptop 2400MHz?

Thanks

Yes.  It will run at the bus speed.

Re: T470 RAM upgrade

Hm would it be 2400 MHz? I just checked Intel's ARK spec sheet on my CPU and it gives me the following:

Memory Types: DDR4-2133, LPDDR3-1866, DDR3L-1600

No DDR4-2400 here. Is that an error on Intel's side? How can I confirm if memory is indeed running at 2400 MHz?
