Hi Good day, I bought an HP Notebook 15-ba047cl and I need to upgrade the RAM, but there's a few issues. So the laptop comes with two slots, one is being used with an 8GB SODIMM. I want to expand the RAM to 16GB and also enable dual-channel mode, but the stick of RAM in my laptop seems to not only be quite rare, but very expensive. The RAM currently installed in my laptop is:
Manufacturer Reference HMA81GS6AFR8N-UH
Short Form 8GB(1Rx8)
Construction Type SO-DIMM
Description DDR4 2400MHz
Number of Ranks 1
Error Correction non-ECC
DRAM Organization 1Gx8
Number of DRAM 8
Construction Type of DRAM FBGA(78ball)
Type Height 31.25mm
I've read HP's documents extensively and they insist I use RAM from the same manufacturer and model number in order to enable dual-channel mode (though I know full well this isn't always needed), but this particlar brand and model is severely problematic to get a hold of. As for my question, I was wondering whether or not I should purchase an entirely new set of 2 8GB sticks, and which ones you would recommend for this laptop, or if there was some way for you guys to assist me in getting just one other stick of RAM from another manufacturer that would work and enable dual-channel mode. I can't seem to find much people, if any at all, mentioning this laptop, and when I try to use the offline hardware scanners and memory finders of RAM manufacturers like Crucial and Patriot, they tell me they currently have no RAM compatible with my laptop.
Side Note: Crucial's offline scanner says they don't have any RAM compatible with my laptop, but when I use the online search on their website by typing in my laptop model, they show RAM modules that are compatible with my HP Notebook 15-ba047cl. They seem to fit the bill as well, being PC4-19200, Single Ranked, 2400Mhz, 260 pin, 1.2v, non-ECC, unbuffered, etc. They seem to match up with the Hynix RAM in my laptop but I'm afraid to purchase it, and also left confused by the whole thing and why HP would choose such a hard-to-find module for a laptop. Please help me, I need the extra 8GB for running multiple VMs and to help my GPU access all of it's shared 4.25GB VRAM when needed, when I play games that use a lot of RAM and VRAM.

I would go for Crucial. If you wish to buy HP RAM, you can buy from

Thank you for your assistance. The link you posted helps. Quick question though. If I buy a stick of Crucial RAM and pair it with my currently installed RAM (assuming I make sure all the specs of both modules are matching), can I unlock dual-channel mode? Or do you recommend me buying 2x8GB Crucial modules and just replacing the current RAM in my laptop altogether?
