What is the maximum amount of RAM I can put on my HP 15-dy2131wm? (33K46UA)

[JBordan]

I was looking forward to upgrading the HP Laptop 15-dy2131wm (33K46UA)'s ram from two 4 GB sticks, to two 16GB. Sounds overkill, but I'm trying to max out what I can.

And a quick side question, can I replace the current SSD the manufacturer had installed with a Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSD? Thanks.

HP only has the service manual for the original 15-dy0xxx model series, so the 2 x 8 GB max memory upgrade info may be inaccurate in chapter 1.

Maintenance and Service Guide HP 15 Laptop PC

You can run this command to see if your notebook can support more than 16 GB of memory:

1. In the search box, search for cmd and click Run as administrator.

This will open the command prompt.

2. Once command prompt is opened, type wmic memphysical get maxcapacityEx and press the enter key.

There, it will show the maximum RAM capacity your PC's motherboard can support.

The capacity is shown as Kilobytes, so you have to convert it to Gigabytes by dividing the number provided in the report by 1,048,576.

The Crucial memory report for your notebook indicates that it can support up to 2 x 32 GB of memory and they sell NVMe SSD's up to 4 TB for it.

You can replace the 256 GB NVMe SSD with one having a greater storage capacity and the Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSD will work fine, but since your notebook's M.2 slot is only PCIe Genn 3.0, the drive will not run at its maximum advertised read/write speeds from the Gen 3.0 SSD slot.

This table shows the maximum transfer speeds each PCIe slot generation can provide:

The output came out as 32, does this mean the laptop can only support a total of 32GB of ram? Or two 32GB ram sticks? 

[Paul_Tikkanen]

The report is 32 GB in total or 2 x 16 GB.

Hi, I forgot to reply originally due to some plans, but will this site provide working memory sticks? It says its the specific ram model for my laptop, but im questioning about it.

I already know it does sell memory sticks, im just wondering if its the right kind.

You need to use DDR4-3200 CL22 memory, so the 8 GB DDR4-3200 CL15 chip won't work.

Thank you, I will be accepting this as the solution.

You're very welcome.
