    @Prema
    Hi !
    I see that reseller 'Dreammachines' is offering 'prema bios' for both clevo based unit pb51rf and pb71rf.
    So maybe you can answer to my questions.

    Actually i've only seen (in the european market) i9-9980hk with PB50RF (so no g-sync) with only 240hz display or with PB71RF-G with 144hz display.

    Do you know if PB50RF(-G), PB51RF(-G) have the same exact motherboard ?
    I mean do NON gsync units still have MUX chips ? If so, can they be re-activated ?

    What i want to ask you is if i buy a PB50RF and than replace stock 240hz display with a certified gsync 144hz panel, will g-sync now work on my new custom PB50RF-G with i9-9980hk ?

    Hi, Meaker! FYI for your Sager team, this system is currently listed as #8 (and #13) on Passmark's Top 20 Fastest Laptops ever page! Even better, if Passmark would accept results within 5% of my previous high score, this notebook would be in 3rd place. As far as I'm concerned, achieving this with a 4K monitor makes this #1!

    Once again, kudos to the team that built such a great product. Well done!

    The desktop chip machines would take #1 too but that's hard for them to detect ;)

    Wow...I should run passmark on mine and push that number up a bit. Mine can hit 4.6ghz which should put it near 4th/5th place.

    It's official. This system is now ranked in 3rd place in Passmark's Top 20 Fastest Laptops page! The only two systems that are faster use K-type (overclockable) CPUs, while this one runs a 9750H with its RTX 2070.

    For those who are interested in trying it out, note that Passmark does require some O.S. tuning to get the best results, but it's definitely a lot of fun.

    Cheers!

    For those who don't like Passmark, it's interesting to note that UserBenchmark rates this system at 97th Percentile (out of 100, only 3 systems with the same components would exceed it). On any benchmark I've run, this is truly an extremely fast machine!

    Been messing around with my PB51RF-G for a while. Here's some tweaks to the memory that might help others with the same RAM (2x8GB Corsair Vengeance 2666). All done with the default timings and voltage:

    Default 2667MHz (133x10)x2 = 38GB's memory bandwidth
    Better (overclock) 2993MHz (133x11)x2 42GB's memory bandwidth
    Best (overclock) 3000MHZ (15x10)x2 43GB's memory bandwidth

    Also spent HOURS with the MSI curve editor. This curve elimates 99% of the power limit throttling in games (still gets odd minor flickers during 3DMark but that's not a realistic load). Memory is set to +300MHZ BTW.
