    please post your 4k results or a screen, thanks in advance.
    The Corsair Performance brings in 8460p much less 4k write than in other systems. Don`t know why, even with enabled c-states there should be something like 50mb/s. Limitation due F.20 Bios?

    F.25 disables Sata 3 6Gb/s! Do not install! Same effect as F.22
    Is HP kidding us? Can't be true that they disable this feature but write in F.22 Changelog "SSD Sata 3 Support"

    I installed F.25. But only read speed drops down. so,
    Seq. read 256MB/s write 168 MB/s
    4K 20MB/s 36MB/s
    4K-64Thrd 135MB/s 140MB/s
    Ac.time 0.19 0.29

    The tech. specialist at HP told me that they use samsung 830 models. I have two ideas. The new bios supports only samsung drives, or it's just a compatibility problems.

    You can check whether SATA3 is working by installing Intel Storage Manager. SATA3 was working till F.20 and HP disabled it since F.22. I don't have a SATA 3 SSD to test if F.25 brings back SATA3. I have reported to HP for countless of times adn it seems they are ignoring this bug.

    By the way, I'm using an old Sandforce 50GB SSD with BIOS F.25. I don't think there is whitelist for BIOS and any should work.

    thanks god I didn't update BIOS from F03 to F25 two days ago !
    Is there any really upgrade or reason to change F03 to newer version (F22/F25)? I'm not going to install QM but I use Samsung 830 - 128GB. Even If I lost SATA III I wouldn't be so furious than If I lost eGPU compatibility which works perfect look!!

    you can return from F.25 to F.20 without problems. But it`s not possible to go back to a version below F.20, thats a fact.
    In my opinion, there are no features that make it worth to do an upgrade from F.03 or F.08 to the newe versions- the fan is still a little noisy and so on.
    @shym_tx: Sata 2/ 300 limits at about 250MB/s so you won`t notice any difference with your ssd.
    HP support says they don`t support Sata 3 for business notebooks- seems to be the reason why they disabled it in F.22 and F.25, it`s no bug for them.
    Don`t know about eGPU- interesting thing but adapter is too expensive to buy without need just for fun :D
    Stay at F.03 and you`re save :)

    Funny enough, that I don´t have any problem at all with my Extrememory XLR8 Express 240GB 31FA (Sandforce 2281 sync NAND, SATA 6Gb/s)
    Read seq 489,57 MB/s MB/s write 230,89 = 607 in AS SSD
    Quite ok for c-states activated and in a laptop

    as long as I don´t have to update the BIOS I´ll stick with my old one

    what`s your 4k value in read and write?
    with F.20 i can reach about 830 Points in ASSSD (Screen on top of this page).
    But low 4k write because of c state is annoying, i`m still in tests with disabled LPM.

    I wonder if any 8460p, 8460w owners here could test if their quad core CPUs can Turbo above stock clocks. Thanks.
