    Hi Prema, any chance you can mod the P150EM bios as well?

    Wow, really shocking how many features the normal BIOS keeps locked. Great job Prema.

    Can you maybe make modded BIOS for the W25AES, it would be greatly appreciated.

    Quick question but does PREMA mod have a factory defaults button still?
    Or once you flash your laptop you will have to re-config everything else?

    What about IDA disassembler?
    Is there any chance to rip pieces of a code from one BIOS an integrate to another?

    It's locked, it won't happen from any of us from this forum...

    Clevo needs to unlock it themselves.

    You won't see extra options in that BIOS without a miracle.

    Someone PM the latest BIOS & EC for that model and I can take a look. Never heard of that model before.

    The Mod Bios doesn't change anything on its own by just flashing it.
    The user has extra options to choose from. All changes are your own choice everything is on default and unchanged. ;)

    That bench was 1280Mhz GPU / 1135Mhz vRAM with GPU voltage @ 1.15v (max possible volt/up from stock 1.10v).

    GPU temp never exceeded 75c.

    That is my cards absolut maximum stable before the driver crashes (,but other cards go higher. HTWingNut can run his vRAM beyond 1250Mhz. Just tried to raise the bar and I am quite excited what we will see from our fellow W11 folks.
    Anyone interested in beta testing PM me. We will have a run during the weekend, to make shure the base clock is stable for everyone.
    Right now 1200Mhz GPU / 1100 vRAM looks good. You guys can push it 135Mhz further with tools then and find your individul cards limits.

    Will it still clock down to 135mhz ?

    YES only boost clocks and voltage are changed. Even regular 2D clocks /volts will remain at stock.

    That's just 0.05v extra and only applied during Turbo Boost to trick NVIDIAs throttle...without that extra the card throttles the voltage when reaching 60c, which makes no sence, since the fans only spin faster once 70c are reached.

    This is all W11 until now, since the W15/W17 use DDR5 they share a different vBIOS...but we will do our best to port it.
    I flashed more than 30 versions on my own W11, something we can't expect a beta tester to do. ;)

    @AlienUFO The voltage of RAM is adjusted by the RAM, the BIOS defaults to "auto".

    We are now testing undervolting of the GT650. So far we droped Idle clocks 0.075v without any issues...your batteries will love it...stay tuned.

    you could try that with default 3d clocks as well; it would be great if it worked; given the ddr3 limitations, I for one would rather not o/c the gpu to keep it cool

    Hello again,
    could you please explain a bit deeper what you mean by
    "locked"?

    Encrypted? Unspecified? Part of BIOS code is missing? Some other protection?

    Every lock should have a key :)

    I have no experience in modifying a BIOS, but it's just a software, at last.

    Well in this case it's so locked that the key you'll be needing is:

    • insane amount of time
    • HEX editor
    • man power of 400 workers
    • a horse
    • and enough redbull to last 2 month without sleep

    It cannot be done alone, nor can it be done as more than 90% of the time you won't know what you'll be looking for

    Prema told me (well not me, basically the whole forum) why he couldn't access it with the basic BIOS tools, and I went to investigate... which led me to a sever rock of disappointing information :( damn you clevo

    hi fellas... installed bios and switched to 1866mhz ram profile, benched, all good. switched to 2133Mhz profile saved and exit. now my computer turns on with no image and shuts down. i assume it's unable to start my stock samsung at such clocks.

    Is there a way to reset everything to defaults? no other changes were made in the bios.

    Tried unplugging the sticks - didn't work for me((

    where's the CMOS located?

    update: found the CMOS, it's pluged to the MB through a cable. Unpluged the cable which resulted in system reset. Now it works fine. Phew...)

    There is a little white plug with a red/black wire next to the hard drive bay and RAM. Pull it up and remove it, wait 30 seconds, and then plug it back in. It's the plug for the CMOS battery which you can see in this image, but usually hidden under the hard drive or SSD.

    Bought 2 sets of Vengeance 1866 DDR3 ram, both sets wouldn't pass memtest. Ordering in a set of Kingston PNP HyperX 1866 instead.
    I will be doing the BIOS mod soon. Just a last confirmation, there is a return to defaults button in the bios still correct?

    To reset everything to default, you will have to pull the plug I noted above. Only do it though with power unplugged and battery removed.

    Yes, there is a "load setup defaults" button, you only have to pull the battery when you made a change that prevents the system from booting. ;)

    Oh, that's what he meant. From the post sounded like it was from RAM clock failure, which would result in an unstable system or not being able to boot.

    HTWingNut exactly! Also, what kind of stock ram you've got: were these the green or black Samsung sticks? I've got the green one... just try to figure out why i was unable to run 2133Mhz settings)

    i cant vouch for other kits but i can share my samsung 30nm green 1600mhz cl 11 experience. I could achieve 2133mhz stable with multiple memtest passes using 12-12-12-30 2n timings. I believe htwingnut could get 2133mhz on stock settings but its luck of the draw. I heard from the alienware guys that the corsair 1866 units dont oc that well. From prrsonal experience, ivy bridge likes bandwidth mote than tight timings

    Hi Prema,

    Thanks again for your hard work, i'm wondering if the gt650 undervolting will lower overall heat output, also how do you achieve this? are you unlocking the vBios? Now for the CPU, any news about the configurable TDP ?

    Clevo deleted the DPTF configuration submenu and acpi module, which are required for the Configurable TDP to work.
    GT650M undervolting is done via vBIOS hardmod.
    Maybe a few of the tester can chime in here with results.

    Thanks for the answer, so basically we have to apply vBIOS to the GPU like we do for the MB BIOS? if yes shall i have this vBIOS and test it please?

    I've been reading this topic but cautiously holding off, as BIOS flashes aren't generally something I enjoy doing unless I absolutely have to, but I have a question - you mention GPU undervolting. If I've forced everything to run on the HD3000 except for those games that I've made a manual exception for, and the 650m does not appear in HWMonitor unless I'm gaming (presumably Optimus is working properly and it's off), is there any benefit to undervolting the GPU at idle? I get just over 4 hours of battery life in this configuration, but if I could significantly increase this by undervolting, I'd probably do it.

    Hey Prema, quick question about the P series BIOS. Any chance you might try working in them later, or you already consider them locked beyond salvation?

    yes; os-installation and bios-change are independent, although, depending on the settings in the bioses (the old and the new), the OS might need to install one driver or another

    Hello Prema, I have a BTO notebook wich is based on a clevo w150erm, perhaps a dumb question but can i use your bios mod for my notebook then? cause on your W150ERQ/NP6165 « Prema Mod site is see w150er instead of w150erm. Would be huge if i can use it, and if anything would go wrong can i use the default bios again or must i contact BTO then for that? Thanx for any help you can give me

    W110ER/NP6110 Prema Mod on the blog updated to version v1.2

    Changelog: - unlocked GT650M Software Overclocking Limit ( CREDIT: SVL7)


    The GT650M can now be overclocked (beyond the regular 135Mhz limit) by using a software like Nvidia Inspector, MSI Afterburner or EVGA Precision X.

    GPU voltage & base clocks are completely untouched/stock on this version. Instead it gives you the choice of how high you want to push it.

    Undervolt & overvolt mods will follow...

    Thank you! :)

    Question: opening it up to EVGA Precision / MSI Afterburner - does that enable fan speed control using their fan speed curve graphs?
