Problem upgrading RAM on Acer Predator Helios 500 PH517-61-R0GX G

I am trying to add 32GB of RAM to my Acer Predator 500 PH517-61-R0GX G.  When I add the two modules  (DDR4 2400 PC4-19200) to the free slots the Laptop does not boot and just has a black screen with no errors.  I tried two different RAM Upgrades with the same result.    What is wrong?  Can someone point me to a memory upgrade that will work in this laptop?

Links to the memory upgrades I tried are below.

    You probably just lucked out and got two bad pairs from Amazon. The crucial pair is guaranteed to work in your ph315-61. I suggest live chatting with crucial https://www.crucial.com/usa/en/support-contact?cm_re=us-top-nav-_-us-flyout-support-_-us-support-contact-chat to get it resolved.   Jack E/NJ

    I think it could be a CAS latency(CL) problem. Download HWiNFO and check the latency of the existing RAM at 2400MHz. If it is lower than 17, then that could be the reason why the pair from the first link didn't work. There is no info about the latency from the pair from the second link.

    Also both pairs have a frequency of 2400MHz while the one/s inside your device work with 2666MHz. In this case you can have 2 outcomes. 1st - the system will work and all modules will work at 2400MHz and 2nd - the first memory channel is the one that decides at what frequency the other channels will work and as the memory installed there is 2666MHz and the memory that you want install is 2400MHz, it won't be able to work at 2666MHz and the system will declare a RAM failure.

    To summarise: it could because of different latencies between the modules or the different frequencies or both.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    Just checked the latency from the second pair is also 17. This is what they have in common.

    I would suggest you to look for memory that is 2666MHz and has the same latency as the one already installed.

    I'm having the same problem with the same memory (ct2k16g4sfd824a). The memory speed is 2400MHz CL17 just like the included memory and the sticks work when testing them on another laptop. The Helios' free slots work also when testing them with a 4GB 2400MHz stick from the other laptop so the motherboard isn't broken either. What's odd is crucial explicitly mentions that the ct2k16g4sfd824a pack as supported for the Predator Helios 500 ph517-61-R0GX on their support page. Should I try replacing/swapping the original 8GB sticks with the 16GB sticks? If so, does anyone have a detailed guide how to correctly disassemble the laptop to get to them? If not, does anyone have a list of tested 16GB/32GB memory sticks that do work with the Helios 500?

    Stev3 2 of the ram slots are on one side of the mobo the other 2 are in the other side you have to disassemble the mobo completely to access all the 4 slots





    and these are the sodimms tested by Acer



    And any hyperx sodimm should work fine with your machine i never used crucial i alwasy used and alwasy will use kingston on all y laptops even if they bring any other brand i will bin it and replace it with kingston never had a single issue either on laptops neither desktops :)

    Well, I just sourced for two extra pieces of the Hynix HMA81GS6AFR8N-UH RAM and it works for me. Found an online store selling these and after I determined from CPU-Z that my Helios 500 came with these, I just got two more and popped them in. Got 32GB, but now RAM speed has downclocked to 2133MHz and Instruction Timing has fell to 2T, but latency decreased to 15-15-15-35. I'm fine with it tho, Sony/Magix Vegas doesn't seem any slower and Satisfactory and GTA V still runs silky smooth, which are the important factors for me.

    So yeah, I think the first thing to do is to scout out the RAM type on your laptop using CPU-Z. A bit tough since either Acer's BIOS is blocking SPD reading or the RAM doesn't have a proper SPD, but I was able to guess it via the info that CPU-Z could get.

    The only things bugging me about the laptop is how two of the RAM slots are inaccessible, and how the GPU isn't on a MXM-II card, and how it doesn't have a ExpressCard slot (really want to throw in a X-Fi Expresscard to make the machine on par with my desktop). But yeah, can't have everything.

    So rather than going through the effort/risk of tearing down my Helios 500 to get to the 8GB sticks, I just ordered a single Samsung 32GB 2666MHz C19 (M471A4G43MB1) stick to try out since I couldn't find any confirmation of whether it would work or not. Relievingly, it does work so 128GB of total ram is definitely possible! Even better, putting one of the Crucial 16GB 2400MHz C17 (CT16G4SFD824A) sticks that didn't work before into the remaining top slot now works... And it instantly rebooted as I was typing this and subsequently failed MemTest86. The Helios 500 seems to hate the Crucial 16GB sticks for some mysterious reason. :/ But at least the 32GB stick works and passes MemTest86 and I'm going to order a second one to attempt 80GB.

    The only downside is the ram is now down clocked all the way to 1866MHz 13-13-13-30 2T.

    I can confirm 128 gb ram works with 4 sticks of 32 gb. I got it last week, second hand off eBay for a grand and did disassemble the whole PC. To be honest the process was not bad ( though I wouldn't want to do this again). The only care someone needs to take is to remember the various connectors to the motherboard. These is also one screw, at least in my unit connecting the motherboard to the laptop chassis. Once disconnected just lift the bottom portion of the motherboard slightly and you can find the internal ram slots) and make sure to have a thermal paste handy, as the cpu and gpu cooler needs to come off as well for the disassembly. Regarding the ram speed, I was able to get them to work at 2400 MHz through ryzen master.

    woah!, 128Gb is it stable ? can you share the brand ?

    I know its an old thread and post, but I was wondering if you could share a screen grab of your Ryzen Master RAM timings and frequency setup for the RAM.
    Thanks.
