    Why was it suggested in here to turn off C1E for the 9570?

    It yields fewer voltage steps and sometimes increases system stability at the expense of consuming a bit more power and increasing power state switching latency.

    Would you mind sharing your TS setup?
    I'm trying to set the TS on my 9570 i7, but lots of these settings are just a big unknown for me, and I just left them at their default settings...
    I value my battery life over the power, so as per your advice I left the C1E on.
    Why turn down the turbo ratio limits? My turbo ratio limits are 41 for 1-2 cores, 40 for 3-4, and 39 for 5-6 cores, those are the unchanged default values.
    Speedshift default values are Min 1 and Max 41.
    Someone mentioned to turn off Clamp in Package Power Limits, so I turned it off.

    Isn't C1E disabled by default on Dell PCs when MEinfo.exe is run? Atleast on AW C1E are disabled by Dell to get more R/W speeds for NVMe drives.

    It showed as enabled in TS on my 9570 when I installed it.

    Eidt: I just checked only the seq SSD speeds with C1E off and on (2 times each), and the read speeds were the same, but the write speeds were 30-40% faster with C1E ON.

    My only request is that you make them smaller. At 1080p those images are way too big. I can resize them if you need, but welcome you to do so yourself, lol.

    *on edit* I have changed your attachment to thumbnails so users can click on them to get a larger image.

    How is this @custom90gt ? I reduced the size by 50%. I forgot my 4k screenshots would be a PITA for 1080p screens. When did you become a moderator btw? It's been a while since I've been a regular on here I guess.

    @Maleko48, thanks those images are much more reasonable.

    I've only been a mod for a couple of weeks now, they just needed someone who was addicted to the Dell forums, lol. You need to hang around more, we could always use the help of enthusiasts like you.

    Wow, that's cool. I moved across the country this summer and work a full time job now 60 hours a week. My little bit of free time these days goes to my family, dinner time, chores, maintenance, handyman tasks, helping family and friends, etc. I've been indulging my weekend spare time on Overwatch too which doesn't help. lol
