    So I am digging for the next couple units to build up, and pondering what is worth it to mess with... My freshly sorted MK6 almost sold right off my toolbox today. It may be gone by the weekend. I almost wish somebody would buy my MK1, but then not sure I would actually sell it if they tried...

    There always seems to be confusion as to max supported memory in each generation. I am surprised as none of my searches for specification lists pointed me back here. I found this though: https://www.toughdepot.com/panasonic-toughbook-cf-19-mk1-mk8/

    I am not sure I believe that list... But I see a few points to ask questions about.

    I am guessing the processor speed jump from MK3 to MK4 is pretty significant? And can they both truly support 8gb memory? The low price for some of these might make it worth considering for a dedicated tuning/diagnostics laptop.

    I am most interested in the MK5, MK6, and MK7.

    MK5 to MK6 is a slight jump, but MK6 to MK7 doesn't seem to really be worth the extra price hike. Doesn't look like a real processor increase?

    Memory, I thought MK5 was limited to 8gb? Can the MK5, MK6, and MK7 actually utilize 16gb???

    I can see some specs I know to be pretty accurate on that list. For my usage, the daylight screens are a game changer. Anything below a MK4 is unusable in sunlight. And for me personally no reason not to stick with an MK6. Especially if I can get 16gb of memory working in it.

    But is there any other specs not listed, like video, that would make a jump from a MK6 to a MK7, or perhaps even an MK8, worth the price difference? Right now the MK6's seem to be the best bang for the buck on eBay.

    Okay some of the questions above were answered already in my older thread trying to decide between the CF-19 and the CF-31 over here:

    Yeah, none of these charts agree with the others, or what you guys have posted up. I wish there was a chart we could actually rely on...

    I saw that one in the other thread, I like it too. But how about this?

    In the list above it says MK5 and up only support 8gb max.

    Well whatever the case if my MK6 supports 16gb, I am super happy.

    Here is Mrugged's chart.
    I will post it in the CF 19 FAQ thread also.

    Shawn, I don't think the max memories in that chart is correct.... According to User32 claiming 16gb working in his MK7 and that MK5 and up support that.

    The problem is I think the truth is somewhere in between. Supposedly there were 64bit MK2 drivers. I suspect that 8gb could be supported on 64bit. So if a MK5 can support 16gb of memory, what is the gotcha? Will it only do so with W10 installed?

    Trust me, I am not asking this without doing the digging first. Problem is the holes dug all contradict each other.

    It is simple.
    The chart is accurate per Panasonic's listed and recommended specs.

    The Intel specs for those chipsets are higher.
    Sometimes the Intel specs work if you source the correct memory module.

    Why did Panasonic spec them lower?
    Who knows?
    Could be a heat issue or it could be a power conservation thing.
    Could be that at the time Panasonic released those models, the larger memory chip was not available on the retail market.

    This has been discussed somewhere on this board. I don't know where it is, but it is here.

    Mk3 & 4 screens are the same and are 1000 nits maximum brightness. Mk5+ are 500 nits maximum, and have a transflective screen which reflects sunlight up to a theoretical 6000 nits.

    If you go for the digitizer screen, mk7 & 8 have a 5 point touchscreen.

    Up to mk5 have two USB 2.0 ports; mk6 up have one USB 3.0 port and one USB 2.0.
