Issue with new DDR3L RAM

Hello everyone,

I have a problem with my father's PC (HP Pavilion 500PC Series - 500-125efm) running Windows 10 - 64 bit.
It only has 4 GB of DDR3 RAM (4GB 2RX8 PC3-12800U-11-11-B1 - 1.5V) out of a possible 32 GB, so I ordered 2 new 8 GB sticks, but I didn't realize they were DDR3L (8GB 2RX8 PC3L-12800U DDR3 DIMM 1.35V).
I have done all the configuration manipulations I found online to get them to work, but I can't.
Is it due to the different voltage?
The PC recognizes 20 GB (but it shows 3.94 GB usable), which seems abnormal to me because when I remove the 2 x 8 GB sticks, I get the same usable value.
The manipulations done:
Setting maximum memory in MS config, disabling the automatic "paging file", I changed the slots for the different RAM, I even went into the BIOS but I cannot find the "Memory Remap Feature".
So I want to return the 2 new RAM sticks and get others, but I can't find any DDR3 8 GB 1.5V. Do you have any advice, please?
I can provide the CPUZ report of my father's PC if needed.

Thank you in advance for your feedback...

Hello, did you test with only the two new RAM sticks?

Hello,
yes, as well. With only 1 of the 2 new RAM sticks, then both at the same time, but the computer wouldn't work anymore. It only restarts when I put back the original 4GB stick.

Hello
Curiously, there are still plenty of listings for 8GB DDR3 1.5v.

https://www.google.com/search?q=DDR3+8Go+1.5v&ie=utf-8&oe=utf-8&client=firefox-b

Mixing DDR3 and DDR3L sticks would only be possible if all operate at 1.5v.
Futura-sciences lists successful cases:

However, there are still compatibility issues depending on the PCs (DDR3L that refuses to work at 1.5v, BIOS, support...):

Hello, thank you for your help as well.

Indeed, I was only looking on Amazon, old habits die hard :-) and I'm trying to find the exact reference since I don't know much about computer equipment and I only come across PC3L, DDR3L 1.35v, 8GB.
I'll look elsewhere then or make a choice from the links I received on the forum.

Thank you very much for your help!

Here are the new memory sticks in question:
https://www.amazon.fr/motoeagle-DDR3L-1600-1600MHz-240-Pin-Ordinateur/dp/B08LQBJ3K9/ref=pd_sbs_3/259-3424724-0907728?pd_rd_w=1qzt6&pf_rd_p=075589f6-3852-493e-aff6-e210133e3ed2&pf_rd_r=WJWW21721T36C6QGYBTF&pd_rd_r=2f6dd493-7ed3-463b-a26b-9e12c6a4fa93&pd_rd_wg=mPIWZ&pd_rd_i=B08LQBJ3K9&psc=1

Otherwise, am I not obligated to use 1600MHz having one original 1600MHz card since one of your links has a 1333MHz? Sorry for the question but I’m tinkering with computers.

For your information, the motherboard is an MS-7778 Ver:1.0

This motherboard supports frequencies of 1333, 1600, and 1866 MHz (But it's a shame to go down, it loses a bit of performance)

I've never heard of this brand, I advise you to stick with the "big" brands, there are plenty of options (G.Skill, Crucial, Corsair, Kingston, Samsung, SK Hynix, Hyper-x, Patriot, Micron, ....)
