I've recently bought an ENVY 795-0050 desktop which comes with 16 GB DDR4-2666 SDRAM (2 x 8 GB). There are 4 DIMM slots, and I understood HP email support to say I could put two 16 GB DIMMs in the empty slots, and they would work with the 8 GB DIMMs that are currently installed (so all don't have to be the same size). Has that worked for other people?
How would I find out which 16 GB DIMMs are compatible? I tried the Amazon partfinder, and it only showed SSD drives - perhaps because the computer hasn't been added to their DIMM database yet?
Also, I'm guessing that the 2666 in the name of the memory I have is the speed - does all the memory need to be the same speed?
Thanks for your help!

You can do what you want to do.
Memory only needs to be in matched capacities in the two slots not populated.
Could be 2 x 16 + 2 x 8, 2 x 8 + 2 x 4...whatever.
I have zipped up and attached below, a free utility that will tell you everything you ever wanted to know about the memory in your PC.
Then you can purchase memory that has the same speed and timing specs.

Thanks, Paul! It looks as if that might help once I have my new computer set up, but I had been hoping I'd be able to buy and install the extra memory before putting the computer under my desk where I can connect it to the monitor. I'll look at it again a little later and see if I can find a way to put in a model or serial number and have it look for the specs from that, if what was listed as specs for the memory on the site isn't all I need to know.

From the specs on the site and the info printed on the box, it appears that the DIMMs that come with the computer are 2666 Mhz (Speed: PC4-21300 MB/s, Type: DDR4-2666).
From what I've read, it appears that I could buy faster DIMMs, but they would only run at 2666 Mhz unless I replace the two DIMMs that are there now, which would cost more than I'm willing to spend. It also sounds as if it wouldn't make that much difference for at least most of what I do on the computer. I usually have several applications open at once, am sometimes logged into wildlife cams remotely to control them, am sometimes recording video from them while controlling them - and posting updates to our organization's website while all that is happening. Once I add a pair of 16GB DIMMs to the new computer, I'll have a lot more RAM, and I think that will help windows open faster and save faster. Does that all make sense, or is there a major flaw in my reasoning?
Hopefully the final question - I found these DIMMs on Amazon - Corsair Vengeance LPX 32GB (2x16GB) DDR4 DRAM 2666MHz (PC4-21300) C16 Memory Kit - and they seem to match everything I could find to check. The only thing I'm not sure about is if this computer is considered intel 300 series - I think it is, and the DIMMs say they are compatible with that - but I'm not sure if that's enough. Amazon's partfinder can't tell if the DIMMs will fit my computer - but their link to show all the parts that will fit don't include any DIMMs, so either this model computer is too new for them to have checked whether the DIMMs will fit - or it's too non-standard for any DIMMs they sell to work with it. I'm guessing they haven't checked the computer - but I don't know how to confirm that. Comments on the Amazon site said it might only work if you removed the current memory, but didn't say what might be different. And the specs don't say what brand of memory is there now. (Note: I'm not committed to the DIMMs I mentioned - the brand had some good comments on the forums I've been reading to try to understand how this works, so I'm using them as an example.)
Thanks so much for your help (and patience!) - it would be a lot easier for those of us who don't know a lot about hardware if HP would sell compatible DIMMs. :)
