I bought a Predator laptop (PT515-51-75L8) and want to know if the following ram is compatible

I've contacted their support, been passed around from every department and apparently no one can answer my question....to the point where they'd pass me off to someone else before hanging up on me. I thought it would be a simple question, so I'm really hoping someone can give me answer on if that will work or if I'll need to go with the 2666MHz option?

    The ram that you have that link to is not suitable for your Acer Predator Triton 500 PT515-51-75L8, DDR4-3200MHz is not recommended. This is the Acer recommended "System Memory" for your laptop: Also install CPUz and look in its SPD section for what spec memory you have OEM installed in your laptop and either match that or get the max spec memory suggested by Acer below:
    • Memory size totals - with 8GB sticks (1x or 2x = either 8Gb or 16GB total into 2 slots) with the 16 GB sticks (you can mix up 8Gb and 16GB into the 2x memory slots e.g. 1x 8Gb = 8GB or 1x 8GB + 1x 16GB = 24GB or 2x 16GB = 32GB)
    • Number of DIMM socket - 2
    • Maximum memory size per socket - 16 GB
    • Maximum system memory size - 32 GB
    • DIMM type - DDR4 SDRAM
    • DIMM speed - 2666 MHz
    • DIMM voltage - 1.2 V
    • DIMM package - 204-pin SO-DIMM

    I have the intention of going to 32gb (2x16gb). What do you mean the "max spec memory suggest"?
    Also, while not sure it matters, I'm fairly certain this is 260 pin.

    Your PT515-51-75L8 has the Intel Core i7-8750H and other PT515-51's come with the i5--8300H (8th Gen)  CPU and the "Maximum system memory size = 32 GB combined into the 2x slots e.g. 2x 16GB" for the "DIMM speed its the DDR4-2666MHz" and is as follows; 2x 16GB DDR4-2666MHz memory that equals 32GB total workable memory, it does NOT suggests or recommends the 2x 16GB DDR4-3200MHz as it won't work, many people have put 2x 16GB DDR4-3200MHz modules into their systems and it didn't boot or work and they wondered why?

    The above is what Acer quotes and recommends for your PT515-51-75L8 that comes with the Intel Core i7-8750H while other PT515-51's come with the i5--8300H (8th Gen)  CPU, in their service manual and its the same for their "DIMM package of 204-pin SO-DIMM" numbers for the Acer Predator Triton PT515-51-75L8 and its not the 260 pin DDR4 SODIMM. Btw, SODIMM pin numbers are like CPU socket types, you cant put an LGA1200 CPU into an LGA1151 CPU socket, take it as you will but, you will find that out when you ordered the wrong DIMM pin modules? As allot of the times, suitable memory quoited by memory manufacturers are the wrong specs and not suitable memory for many laptops and computers, I found that out the hard way.

    This is the only memory that Acer recommends for the exact memory types in their service manual for the Acer Predator Triton PT515-51 and your specific 75L8 model:
    • MEMORY KINGSTON SO-DIMM DDRIV 2666 16GB ACR26D4S9D8ME-16 LF+HF 1024*8 - Acer part # - KN.16G07.028
    • MEMORY HYNIX SO-DIMM DDRIV 266616GB HMA82GS6CJR8N-VK LF+HF 1024*8 1XNM, AL - Acer part # - KN.16G0G.031
    • MEMORY KINGSTON SO-DIMM DDRIV 2666 8GB ACR26D4S9S8ME-8 LF+HF 1024*8 - Acer part # - KN.8GB07.042
    • MEMORY HYNIX SO-DIMM DDRIV 2666 8GB HMA81GS6CJR8N-VK LF+HF 1024*8 1XNM, AL - Acer part # - KN.8GB0G.058


    204 pin


    260 pin

    Thanks for the suggestion of CPUz, the part number from that confirmed that it was 260 pin.

    Also I'm not sure how you got anything useful about upgrades from the manual.

    In case anyone else comes along asking a similar question, it did work, but it was downclocked to 2666 Hz. Still it works quite well.

    Hey, my machine's a "Predator Triton 500 PT515-52 / Acer Part Number: NH.Q6WEK.003" (the 2020 model with RTX2080 & i7-10875H, 16Gb/1Tb) and I am really struggling to get 2 x 16Gb SODIMM's / RAM that will run as per the OEM (Samsung 2 x 8GB) RAM @2933. Crucial stated their 3200 Ballistic RAM was 100% compatible with my very specific SKU & details (as did their silly tester) but it's not & defaults to 2666, only supporting 3200 in XMP2 & in fact, all JEDEC modes, its merely 2666 (to be clear, I understand the max on my system is 2933 - I am not trying to achieve 3200 - its merely that they said this part would run @ 2933). The information required is if the DIMMs support 2933 in whichever JEDEC modes the 515-52 needs - as opposed to XMP (XMP as we all know is not supported) - but none of the RAM manufacturers / retailers state this in their pre-sales bump anywhere - so its extremely difficult to purchase correct parts. I will have to, once more, remove the PCB to exchange the RAM again (from Crucial to ????) - but only once I truly have 100% compatible DIMM's to replace them with (otherwise I have to repeat the tear-down process yet again). There's some Kingston RAM which *might* be correct but it's over-priced (35-40% higher price than most 2933 alternatives) & I want to be 100% & pay a fair (not necessarily cheap - a fair or reasonable) price for it. Any suggestions about the specific RAM or a supplier would be a great benefit (I appreciate there's little difference between 2666 & 2933 in real world - but I'm a stickler for details). Thanks in advance!
