    I flashed the edited bios and changed the settings as shown in the guide on my Razer Blade base 2018. I thought flashing back to the original would reset the edited settings, but saw TS reported lower wattages after flashing back. Do any of you have the original values for the settings for bios?

    Also, to get it to report even lower wattage, how can i tweak the IMON? When it should report 60w, after the tweak it reports 32w. Is there someway to get the reported wattage down to 10-15watts? I want this because the all core boost caps at 3915MHz on full load, and temps max out at 74C, so I have more thermal headroom here. If i get the system to report 10-15watts, I think I may be able to get the full 4.1GHz boost all core on the 8750h.

    Increase the IMON Offset.

    If you want to let it have an offset of -42W, just put 42000, just make sure the IMON Prefix is set to negative.

    However, some models seem to have a different maximum offset you can go up to, so you'll have to try and see.

    By the way the multiplier of the 8750H is hard locked. So unless you increase the BCLK, you are stuck with 3.9GHz @6 core active.

    Increasing the BCLK is done through microcode I believe, haven't tried it myself.

    Sorry if already asked but can you (and should you) do this on a 2019 blade?

    You can do this and it works great. "Should" is up to you.

    I've been working on getting some more options available in the BIOS that don't become available just by changing to USER in AMIBCP. My initial observations are below:

    1)
    Original:

    Modded:
    [​IMG]

    I know it doesn't look like anything at this point, but changing
    0x308C5 Form: Main, Form ID: 0x2711 {01 86 11 27 09 00}
    0x308CB Suppress If: {0A 82}
    0x308CD Variable 0xD39 equals 0x0 {12 06 39 0D 00 00}
    0x308D3 Text: Access Level {03 08 17 00 02 00 18 00}
    0x308DB End If {29 02}
    0x308DD Suppress If: {0A 82}
    0x308DF Variable 0xD39 equals 0x1 {12 06 39 0D 01 00}
    0x308E5 Text: Access Level {03 08 17 00 02 00 19 00}​
    to
    0x308C5 Form: Main, Form ID: 0x2711 {01 86 11 27 09 00}
    0x308CB Suppress If: {0A 82}
    0x308CD Variable 0xD39 equals 0x0 {12 06 39 0D 00 00}
    0x308D3 Text: Access Level {03 08 17 00 02 00 18 00}
    0x308DB End If {29 02}
    0x308DD Suppress If: {0A 82}
    0x308DF Variable 0xD39 equals 0x0 {12 06 39 0D 00 00}
    0x308E5 Text: Access Level {03 08 17 00 02 00 19 00}
    Removed the "Access Level" line from the BIOS page.


    2)
    I've got the RB15 advanced mid 2019 BIOS allowing selection of default, custom, xmp1, and xmp2 profiles for memory. My chips don't have xmp profiles, so can't guarantee these work. The custom profile, however, does work and sticks after boot. So far I've only tested that decreasing the multiplier decreased my frequency appropriately.

    Now I'm trying to see what else I can get done with these changes.

    That's great!

    Since you got to the RAM timing page, so you got the whole Overclocking menu to show?

    You can lower the tREFI by 10 and do a cmos clear and see if RAM setting resets back to default value (It may still be on custom profile), if it does you are very much qualified to OC the RAM and still can clear the setting using CMOS clear.

    To OC to somewhere like 3467MHz or higher you'll need to increase the uncore (Called System agent in ThrottleStop)'s voltage offset by at least +100mV to stabilize the memory controller.

    See my signature if you need more info on RAM OC'ing.

    I can change all settings and they stick correctly. And cmos clear, had to several times while overclocking my RAM. I will look into your signature link and see if I can get even more out of my RAM.

    Looking into the link @hackness provided, I've got my memory OC'd nicely on my RB15a mid 2019. My 2666MHz is running stably at 3200MHz and showing some great improvements. Took a couple of days of messing around with the BIOS for this system, but glad to finally have it all figured out and working correctly.

    In AIDA64 benchmarks
    .................Original...............MemOC'd..............Improvement
    Read........34544 MB/s.........45405 MB/s...........31.4%
    Write........39478 MB/s.........48871 MB/s...........23.8%
    Copy.........34022 MB/s........44450 MB/s...........30.7%
    Latency.....85.2 ns................57.1 ns..................33.0%

    Wow that is awesome. Could you make a guide?

    I will start writing something up in a couple hours. It is a bit more intensive than the modifications in the OP, but anyone should be able to do them with some simple instructions.

    Which Razer version do you have?
