I want to get a 32gb single stick of DDR5 RAM for my Dell Inspiron 7620. This has 8gb soldered to the mobo and one slot of changeable RAM currently 8gb. If I purchase this from Dell it would be £225.

The spec is 2Rx8 DDR5 SODIMM 4800 MT/s - the latency is not specified
I can get this spec direct from the Crucial site at £142 https://uk.crucial.com/memory/server-ddr5/mtc20c2085s1tc48br
Or Crucial also from Amazon at £85 https://www.amazon.co.uk/Crucial-CT32G48C40S5-4800MHz-Laptop-Memory/dp/B09RVNMGFH?th=1
Here's a Corsair for £85 https://www.corsair.com/uk/en/p/mem...5-4800-pc5-38400-c40-1-1v-cmsx32gx5m1a4800c40
Very confusingly Laptops Direct lists a number of Kingston modules with these specs at different prices with nothing to distinguish between them https://www.laptopsdirect.co.uk/nav/rsc/32gb/ramt/ddr5/rms/4800mhz/mc/components/pt/laptop-memory

Some of these state the ranking - 2R - and the chip organisation - x8 - and some don't. Some list the latency, some don't.

So it all boils down to, how do I choose between these or the multitude of others that are out there? If I get the cheapest from a reputable brand is there a downside? If I pay more what do I get? Can I be sure they're all compatible with the Dell?

According to this;
https://www.dell.com/support/manual...7267e0-5ef3-49ad-b6c5-f66548ee0ff5&lang=en-us
the most you can drop into the slot in terms of frequency is 4800MHz. As for matching the stick of ram with the memory soldered onto the board, that's impossible to do unless you know the factory where the board was made and IC maker's off of which Dell sourced said IC's from.

In short, you're free to drop in any stick of ram with any sort of latency so long as it's 4800MHz. I would choose the one that's priced cheapest. While you're here, make sure you're on the latest BIOS version for your mobile computing device to ensure maximum compatibility.

Thanks for the reply. Yes, to be clear, I'm only looking for the specs listed above. The point of the question is that there are many different modules available with those specs, at different prices. You suggest getting the cheapest - but do you know why some are a lot more expensive and if there's any benefit in getting them?

Like most things you find price alone is not a good indicator of quality. You see things like some brand name salt sold for twice the cost of generic. You pay extra for the company brand name on the front of the package.

Almost none of the memory brands you find actually make the memory chips. If you really want to dig around most times you can find which brands of chips are being used. Even within memory chips there are different tiers.

All this is for people who plan to push the memory above the minimum standards. Even then price alone is not the deciding factor. All models that use a particular more expensive memory chip on the board will cost more but there is still a large price difference between vendors that use exactly the same chips on the modules.

I suspect because dell is just saying use 4800 which is the base they also only support the base latency. So even if you were to buy high end memory the laptop would not use the feature. Kinda like buying racing tires for your economy car that has a speed limiter in it.

The only thing I think you would worry about is if you were to buy some memory from some unknown vendor on say ali express or temu. You take the chance it is a fraudulent product.

Now some memory has a better warranty and that would increase the costs but memory seldom fails after it is running.
