Question RAM for ThinkPad T480

[yegor99]

I'm trying to get the best possible RAM (preferably a kit of 16GB in total) for Lenovo ThinkPad T480 with i5-8350U. What I've found so far:
1. 2x Kingston HyperX HX424S14IB/8 which is 8GB 2Rx8 DDR4-2400 CL14-14-14. But couldn't be found neither on used market nor brand new.
2. Kingston HyperX HX424S14IBK2/32 - a kit of 2x16GB 2Rx8 DDR4-2400 CL14-14-14. 32GB will be overkill + also isn't available.

Available options are:
1. Kingston HyperX HX424S14IB2K2/16 which is a kit of 2x8GB 1Rx8 DDR4-2400 CL14-14-14.
2. Kingston Fury KF426S15IB1K2/32 which is a kit of 2x16GB 2Rx8 DDR4-2666 but will work on DDR4-2400 CL14-16-16.
3. 2x Crucial CT8G4SFD824A which is 8GB 2Rx8 DDR4-2400 CL17-17-17.

What is the best all-round performing RAM out of those 3 available options? Is it possible that dual-rank module with CL14-16-16 or even CL17 will perform better than single-rank CL14-14-14?

Are there any other dual-rank 16GB (2x8GB) DDR4-2400 kits with low timings?

All of those ram kits have C1 except for the Crucial listing which has 17. The Crucial is the slower one when compared to their timings.

At allegro.pl there is HX421S13IB2K2/16 with CL13
And in amazon.de there is a kit HX426S15IB2K2 / 16 with CL15
cl15 is very good latency look and HERE if you are from UA

The one from Poland with CL13 is 2133MHz. The Eldorado (Ukraine store) doesn't have them in stock. The one on German's Amazon can be purchased locally (#2 in "available" list, but it's 32GB which is overkill for me. Typical usage is 8 to 12GB) costs 1.5-2.5x more compared to used HX424S14IB2K2/16 and has worse timing, although dual-rank. The question is: Will dual-rank module with CL14-16-16 or even CL17 perform better than single-rank CL14-14-14?

What is C1?

 

[Lutfij]

I just noticed the 4 didn't register in spite of pressing on the key. I meant to say C14.

The Eldorado (Ukraine store) doesn't have them in stock.
You're located in Ukraine?

You would be hard pressed to detect any performance difference among your choices without a synthetic benchmark.
If you are heavily multitasking then 32gb may be a plus.

You're located in Ukraine?

Yes
Can you please tell me if the fact that Crucial memory module is dual-rank might help compensate for its lower timings?

Looking for Kingston like this , don't use crusial

Get the hyper x 2x8.
If you want to pick nits I think you will find single rank wins over dual rank.
