    @Alejandro_AC

    Can thermal pads be reinstalled after being removed from RAM? Or can they not be glued back on effectively? Are they suitable for modules with components on both sides of the board? Does the service manual say anything about this?

    Can you provide a service manual for the PH18-72?

    We can't provide you with a full service guide for the Predator Helios PH18-72 laptop as its only available to Ace ranked members of the forum, but we can assists you with whatever you need. For thermal pads, also have a look at the Thermal Grizzly range of thermal pads as they are of a high quality also and would be suitable for this high end laptop. Hope this helps you out.

    For ram upgrades Acer suggests a max of 32GB 2x 16GB DD%-5600MT/s CL46 but Crucial suggests a different max total of 64GB, so look here at Crucial PH18-72 laptops suggested ram upgrade, as Crucial suggests a max of 64GB 2x 32GB DDR5-5600 • CL=46 • Non-ECC • SODIMM • 262-pins • 1.1V • 2Rx8 based • PC5-44800 and they even have a 98GB ram kit for DDR5-5600MT/s CL46 that you have a choice to upgrade, as I can't guarantee that the 98GB kit of ram will work in your PH18-72 laptop, so you upgrade at your own risk.

    Below is a list of all the thermal pads used in the PH18-72 laptop including the also the ram and M.2 SSD foils that Acer wraps the ram and M.2 drives with to disperse heat.

    @StevenGen thank you for your answer. Please tell me more:

    1. Does the service manual say anything about the possibility of disassembling and reusing the 47.QMBN7.001 (or they are singe use only)?
    2. Is there a different thermal pad for double-sided RAM?

    That ram foil part #: 47.QMBN7.001 can be reused and they can be used with double sided ram, another way of insulation the ram and M.2 SSD is to just cover the top of these modules with a high quality thermal pad.

    @StevenGen thank you - one more thing:

    how to mount these radiators on double-sided RAM? Does the manual say anything about it? I'm asking because I see a copper field in the illustrations - so it looks like the stickers are not symmetrical?

    I've already confirmed that 64GB works in my reply above. Exactly what additional confirmation to you need?

    I own a

    ph18-72 just getting it this past Xmas. and I will confirm you can upgrade it to 64GB or Ram…(not 64MB of ram.

    You can also upgrade it to 96 GB of ram (

    Mushkin Redline Notebook – DDR5 5600 Gaming Laptop DRAM – 96GB (2x48GB) SODIMM Memory Kit – 5600MHz (PC5-44800) CL-46-262-pin 1.1V RAM – Dual-Channel – Low-Voltage – (MRA5S560LKKD48GX2)

    does work just fine in the system capped at 5200 (Not 5600) Mhz.

    I believe this is an intel chipset/intel cpu cap on the ram on anything above 32GB in ram speed as it seems to be standard across all i9-14900HX processors laptops no matter who makes them.

    As far as SSD the system has no problem seeing either an 8TB Samsung 990 Pro or an 8TB Western Digital SN850X.

    as I have tried one of each in the 2 slots on the motherboard at the same time…this was done to see which drive worked better and honestly I couldn't tell a difference. I then put 2 Samsung 990 Pro 4TB drives in raid configuration on the board and it is my new daily driver computer.

    Hey Taz29926, give us the link to where Mushkin states categorically that their "redline" ram works at 96GB @ 2x 48GB DDR5-4800MT/s CL40 or DDR5-5600MT/s CL46 with the Predator laptops of the model PH18-72 or any of the Predator Helios Neo laptops.

    I know that they have the DDR5-4800MT/s CL40 or the 48GB DDR5-5600MT/s CL46 ram but they don't have any guide of their ram for any laptops, yes I know that the Intel 13th Gen and 14th Gen cpu's have a "Max Memory Size (dependent on memory type) of 192 GB" but it doesn't mean that these higher ram capacities will work in these laptops and at a cost of AUD $469.20 in my neck of the woods for the 96GB kit (2x48GB DDR5-4800MT/s CL40) they are not cheap, as Mushkin make DDR5-4880MT/s and DDR5 -5600MT/s @ 64GB and 96GB modules also, so will they work also, let us know, as this will be very useful information for Acer consumers who need more ram for their business applications.

    Btw, I've got my PHN16-71-50JG which is an i5-13500HX/RTX4050 model running with Crucial 2x 32Gb DDR54800MT/s CL40 type ram and it works perfectly and without any frequency drops and runs at 4800MT/s perfectly, below is the Task Manager:
