I need to upgrade my laptop memory from 16 to 32 Gb. The options I found don't have all timings specifications, so I'm lost. While the first one has the best latency (all others are 46), I can't decide based only on that.

So I found these (price difference is mostly negligible, however, I can get some faster than other):

  1. Kingston DDR5-5600 Fury Impact/CL40/KF556S40IBK2 for 93,5 EUR
  2. Kingston DDR5-5600 KVR56S46BS6K2 for 76 EUR (not sure if this is 2*16, could be 2*8. Nevertheless, the best known shop to me and the nearest, too).
  3. G.Skill Ripjaws DDR5-5600/CL46-45-45/F5-5600S4645A32GX1-RS for 100 EUR (not the best experience with this brand previously, got faulty module, they changed it, but I lost time).
  4. Crucial DDR5-5600 CT16G56C46S5 for 90 EUR

Any thoughts?
Please, do not recommend anything not on the list. I'm going to buy from the local shop, never order RAM from abroad (except for really old PCs). This list is final, closed. I can consider something else based on some strong arguments, but I'm almost sure it won't be available locally, so I'll be back to this list again. Do not suggest any other RAM speed, I don't want lower, and the higher is not supported.

I've also just got new info from the seller. 2 is not an option (it's 2*8), first is a bit more expensive and the model number differs: KF556S40IB-16 for 97,4 EUR.

Also, I have more timings now, first is CL40-40-40, others - CL46-45-45
