I want to add RAM and while buying one should I consider the "Rank" from SPD tab ? Should I add another RAM with Single rank , if yes how do I check on amazon because I checked some RAMs and it is not mentioned anywhere on amazon ?

Laptop: Acer nitro 515-42-R6GV




I am planning to buy one of these. Please have a look and let me know if I am selecting the wrong one.

You don't need to worry about the Ranks, you can even mix single and dual rank modules, it won't affect the performance.

To avoid incompatibilities, I suggest you buy another memory identical to the one installed: ao1p26kc8t1-bpxs

I am from India and I too thought so but I am not able to find the exact same RAM on Amazon.in  or any Indian website.

I would opt for ram from this link: https://www.amazon.in/gp/product/B07FS5WLJW/ref=ox_sc_act_title_2?smid=A17AW1CHVG2YBO&psc=1

Hi,
You could try ADATA module it has different latency(19), it may work but if it doesn't you can return and get a 2400MHz module,either a Kingston or Crucial and install, I have also tried to find a 2666MHz module with CL=17 but none available, have you tried an auction site?
How about this? It is 1000Rs more than what you are looking at and in addition there may be delivery costs and import duty but worth a look:

https://www.ebay.com/itm/Crucial-DDR4-RAM-8GB-16G-LAPTOP-2400MHZ-2666MHZ-2133MHZ-1-2V-CL17-Memory/383153716737?hash=item5935bdbe01:m:mkKvTJDrQeyRJWIGzvfUclg

But the speed of 2666mhz would only be reached with cl19 in the ram that is installed. In addition, the ao1p26kc8t1-bpxs ram also has cl19, see: https://www.impactcomputers.com/ao1p26kc8t1-bpxs.html

Hi! Fellow Indian.
If you are buying from Amazon, check if the seller has exchange or return policy. That way you can take risk of getting an incompatible RAM.
Try this model (No return on this product)-
https://www.amazon.in/Premier-2666Mhz-SO-DIMM-Memory-Module/dp/B07FS5WLJW
You can ask local shops to get a DDR4 2666MHZ module and test if it works. That way the responsibility of working goes on the shopkeeper.

Also make sure to choose a 2666MHZ RAM. It won't cause the problem, but your motherboard will use the lower of the two frequencies. For example, if you get a 2400MHZ RAM, you preinstalled RAM will also run at 2400MHZ. Not much difference but getting the matching frequency won't hurt.

@brummyfan2 But with cl different, would dual channel be enable.
