    It's funny you mentioned the controller swapping, I had just read an article about that being done on the 970 Evo Plus. I don't think I've seen it on any PCIe Gen 4 drives but certainly something to look out for. As for the rest, I agree that these upgrades are negligible. I can't divulge all of the reasons I've chosen to buy everything I can top of the line for this system, but it certainly factors more into my decision than my expectations of revolutionary differences between the components that came with it and the ones I have replaced. The fact that it comes with the 3080 16GB with 165W TGP, PCIe 4.0, Thunderbolt 4, USB 3.2 Gen2, WiFi 6E, etc is already plenty fast, especially coming from a 6 year old Skylake system. I can only imagine what performance improvements will exist 6 years from now when I replace this. Another point to me made is that real performance breakthroughs require a desktop setup anyhow. Not saying my laptop is not more than enough, but if someone is looking for bleeding edge then desktop is where they will need to be.

    You can go bleeding edge on a laptop as well if you're willing to give blood for it. Attachments make anything possible but, then your portability suffers carrying everything around. There's always a trade off somewhere.

    Here's some information that would help on Balistix Cl16 3200MhZ RAM:
    https://www.crucial.com/memory/ddr4/bl2k32g32c16s4b

    Response from the merchant:

    "A pair of DDR4-3200 Ballistix RAM could run at DDR4-2666 speeds if XMP was not running as an example, or it could run at 3200 speeds, but with a slower latency. This is all okay, since most of our memory is designed to run at multiple speed settings. We're sorry to see that you have already returned the RAM. If in future if you change your mind, we would be glad to assist you with the memory troubleshooting. We would request you to contact us directly using the information that we have provided below so that we can assist you further. We hope that the above information has answered your question.

    The RAM in question would only work at CL16 and 3200 MhZ if you can overclock the sticks via XMP profiles in the BIOS.
    If you don't have XMP profiles option enabled in the BIOS itself (and most laptops don't because the OEM's don't like it when people do ANYTHING that might be used to overclock the system), then the latency would likely be higher and the RAM speed would likely be lower if everything is at default.

    The only way you can potentially ensure that your RAM is operating at decently low latencies and high frequencies it advertises is if you can get a RAM with low JEDEC timings (such as say CL17) and high frequency right out of the factory like this one:
    HyperX Impact HX429S17IBK2/64 Memory 64GB Kit*(2x32GB) 2933 MHz DDR4 CL17 SODIMM
    https://www.kingston.com/dataSheets/HX429S17IBK2_64.pdf

    That's the only laptop RAM I know of which has low timings and higher frequencies independent of the XMP profiles.

    Unfortunately, laptop RAM is frequently produced with low speeds and high timings (unlike the desktop counterparts)... and because of the usual lack of XMP profiles in laptop BIOS, its virtually impossible to use XMP ready so-dimms to run at their optimal speeds.

    On AMD laptops that have desktop grade CPU's for example, its possible to sometime use Ryzen Master to affect the frequency and timings of RAM... however, this can be dangerous because the changes are integrated on a BIOS level... so if you set up the RAM timings and frequencies to something the RAM can't handle, you risk not being able to use the machine anymore (short of a hard BIOS reset which isn't always guaranteed to work on a laptop, and of course a potential reprogramming of the BIOS chip itself with the stock or latest functional BIOS version).

    Unless your machine comes with XMP profiles option in the BIOS, I don't think you'll be able to modify the RAM speeds.
    As such, you might be better off getting a RAM such as HyperX Impact HX429S17IBK2/64 which has low JEDEC timings and high enough frequencies (2933 MhZ - which when combined with low latencies would effectively be just as fast or faster than 3200MhZ RAM with higher timings)

    Thank you. My MSI BIOS is highly customizable and I got the Crucial Ballistix 3200Mhz CL16 and it runs great in Gear2. Now I'm playing with trying to get it to run in Gear1 without errors. Someone mentioned lowering the TRFC to 500 (default is 560) so I'll give that a shot. If that doesn't work I'll switch back to Gear2 and just be happy with it. This is the fastest RAM they make for the 11800H so I've got no complaints.

    You can check with @Falkentyne for proper tuning.

    'Fastest' is very relative though.
    As I said, a 2933 MhZ so-dimm with JEDEC timings at CL17 would definitely run as fast if not faster than say 3200MhZ so-dimm which has high timings of about CL20 or 22. If your RAM is running at advertised speed and timings (3200MhZ and CL16 as is), then you don't have much to worry about and I doubt you can improve upon that - I certainly wouldn't try to push it beyond those parameters.
