    Huh, I did this a while ago and was trying random things all at ounce so not sure what allowed me to downgrade all the way down to the UV bios version. Did you make sure that in the bios, the auto-update bios setting is disabled ? You can also try restricting bios rollback to to v1.01. One last thing you can try is to modify the system date to 2019 see if that allows you to downgrade if it has a "check date" security.

    Ok, so I'm guessing you have an LVDS m6700 as that imac vbios disables eDP on DP_D, meaning impossible to get the internal screen to light up unless you are using a eDP backlight mod cable. You are in LVDS switch graphics right ? Looking at the imac vbios : https://forums.macrumors.com/threads/imac-2011-maxwell-and-pascal-gpu-upgrade.2300989/post-31573011, it's supposed to have +250mhz core and +1000mhz vram. Did you test the stock ES vbios (no modding) ? As for the p3000 the ES vbios has higher clocks than the imac vbios : 1820mhz vs 1657mhz. Your modded 150w imac bios performs worse than the 115w imac vbios correct ? What is the limit reason in GPU-Z when testing a benchmark ? You can do one run of 3D mark time spy with 150w + record in GPU-Z and do another run with the 115w + record in gpu z as well to compare what is limiting your performance in GPU-Z "PerfCap" as well as to see when the clocks are dropping and to what values.

    Yes, here you go, I tested this one as working on precision 7720. Flashed with CH341a & 1.8v adapter. I could get it to hit 100w @ 1650mhz in furmark. In other benchmarks and games, it would hit 75-80w @ 1820mhz The card is still limited by that max clock, with no way to overclock via software, vbios OC is possible but you have to be one of the wizards at macrumors. For example my GTX 1060m that I modded to 110w can be sotware OC, 2100mhz on core is possible + you can OC the vram. Also keep in mind the only change I made is bumped the TDP to 100w, using the method I described you can also enable more options that mobile pascal TDP tweaker gives, such as throttle temperature + power slider in msi afterburner. When I get my m6700 back in a few weeks I will try my p3000 in it and attempt to make the "Ultimate p3000 vBIOS" that I'll post on techpowerup (if sucessfull). P3000_ES_m6700_100W.bin

    Hi, Do you have an eDP version of the m6700 (3D screen or DreamColor lcd ?) If so, the only way to get a picture on the internal LCD will be to use the engineering vbios of the p5000m. The macrumors vbios outputs eDP on DP_C and m6700 has it's eDP routed to DP_D (standard for all vbios of the p5000m that have eDP). I also had problems getting a TDP modded vbios card to post. I came up with a solution for my p3000m : -> Edit the p5000m engineering vbios in mobile pascal TDP tweaker -> Increase the max power and other changes (I recommend power slider too) -> Save the modified TDPED version -> In a hex editor, open that modified version and remove the header section of the vbios like so : -> Remove everything before the UaxëK7400éL line -> HxD will say "file size will change" -> Save file -> Flash it with external programmer This worked to get a 100w version of the p3000m bios to post, my testing was done on a precision 7720 that doesn't suffer from the ACPI error that the non ES version of the vbios gives to m6700. Maybe removing the header section will cause the card with this "headless" ES version of the vbios to have ACPI error again ? Anyway worth a shot, good luck !

    Hi, do you have the model number for the LCD ? an app like hwinfo can find it, there might be a smilar type of app for linux too. Until now it was not know if the m6800 covet also came factory with eDP motherboards, only LVDS had been confirmed.
  6. JadeRover
    Hi, I can assist you if you need, the usb method is the only way I think.
  7. JadeRover
    You can also attempt this to get unlimited multpliers, requires bios mod to inject the microcode however, not sure if it's been done on m6800 https://www.techinferno.com/index.php?/topic/9636-tutorial-4ghz-overclock-i7-4xxxmqh-to-i7-extreme-conversion-intel-haswell-cpu-microcode-bug-hack/

    You tried the latest driver w/ p3000 support ? You need to tick Add Hardare support and do : Template : type in p3000 and select the first one (version doesn't really matter that much) Id : type in the numbers it gives you on the right of the field in "Installed :" (just like screenshot) Name : have fun 😄 you can type in anything and windows will keep the name If you use "method compatible with anticheat" you'll have to export the driver to exe, then reboot windows in no driver enforcement mode (google it), then install the exe you exported, you can reboot again in normal windows mode after that.
  9. JadeRover
    Yes install driver in windows, you might need to inf mod, (use nvcleaninstall for simplicity) in bios you should have "unrecognized display adapter" or something like that. The fact that you have picture means that the vbios worked

    That's a very nice project indeed ! Keeping the interest in these old precision alive, especially info on the rare m6800 covet ! One small thing I noticed while looking through some of your sections, under the CPU and GPU : The m6800 didn't ship with any IPS screens, I think you are referring to eDP screens (that offer upgrades to IPS lcd, instead of TN that is garanted with LVDS). All pascal cards and above don't have support for LVDS, it is possible to run one in the m6800 it's just that optimus must be turned on so that the internal dipslay gets a picture from the iGPU. With an eDP screen, the pascal GPUs can run the display directly, without using optimus. Upgrades to an IPS eDP FHD display is possible required you have an eDP motherboard, m6800 shipped with both eDP and LVDS motherboards.

    Looking at the CVEs, for the zbook 17 g6 you'll need to go back as far as v01.02 I got all of them from the official HP driver website, here is the page for your g6 (under "see revisions history") : https://support.hp.com/ca-en/drivers/swdetails/hp-zbook-17-g6-mobile-workstation/22892902/swItemId/ob-352280-1 You'll need to download the exe, run it and chose the option to install to usb. Then on the zbook, plug in the USB and boot to the bios and go to : Main -> update system bios -> make sure "lock BIOS version" is unchecked + "unrestricted bios rollback" is selected -> "Update system bios ... using local media" Normally that should do it, I think you'll need to jump slowly down to v01.02. There is no risk of corrupting the bios if you have power plugged in + charged battery Only downsight is that having to go as far back as v01.02 might make some BIOS features that got added later dissapear.

    Hey all, I have the zbook 17 g5, You can control fans with NotebookFanControl : GitHub - hirschmann/nbfc: NoteBook FanControl and use this profile for Zbook 17 g3 : Current Fan Speed Negative Value · Issue #501 · hirschmann/nbfc You can control GPU and CPU fan independently + create your own fan curve Bought it last year with bios v1.24. I went down to v1.08 going through : v1.24 -> v1.20 -> v1.18 -> v1.14 -> v1.12 -> v1.08 using the plugging in usb method and selecting the "update bios" in the bios setup. It didn't always downgrade, not sure why, but I got there in the end by jumping a few versions at a time. It was a massive pain but now I can undervolt and the 8850H I have has +400mhz OC option that gets enables meaning in theory it can run all core at 4.7ghz (never saw it happen, all core 4.45 ish possible @ 100 watts, -110mv, crashes)

    Hi, I have a zbook 17 g5 that has an identical chassis to the g6 version. I'll quickly list pros and cons that matter to me (you can ask me other stuff too): PROS : - Last worstation laptop to have a bluray player, can be swapped out for a HDD, not available on the 15 inch version. - Last worstation laptop to have MXM 3.0 standard connector, not available on the 15 inch version. Meaning upgrade up to MXM 4090 is possible - All metal chassis, feels very solid, rounded edges, 0 flexing. - Screwless maintenance hatch gives access to 2x ram slots, 2x sata/nvme m.2, 1x2.5inch sata drive, dvd player, wifi + wwan. CONS : - Big screen bezels - Other 2 ram slots + 3rd nvme slot is behind the motherboard meaning you need to remove the entire motherboard to access them (dumbest workstation design I know) - okay keyboard, kinda shallow compared to my precision 7720. - ram limited to 2400mhz by BIOS, no option to change it - undervolting only possible with v1.12 bios from 2019, downgrading is a pain. - best cpu option is 9980H (non K) also the 8950HK is possible but it's 6 cores Currently running the 8850H undervolted -140mv, unlocked boost to 4.4ghz 60w power limit, 75°c in games

    HDMi always uses dGPU, eDP screen or LVDS screen. RGB-MB (Dreamcolor) screen has a direct connection to dGPU if you can get it to work, so this screen is also full performance. eDP 3D lcd cable is the most versatile one as it can connect a 40 pin eDP screen to modern GPUs,+ there is no display port demux between MXM gpu and eDP connector on the motherboard : Meaning that the eDP version is theoretically limited to the one on the MXM side, meaning 4K120hz+ lcd upgrades are possible with this cable.
  15. JadeRover
    Actually there are also these vbioses : But you need a SPI 1.8V flasher to get the vbios on the card, using nvflash won't work. These vbioses have different display tables and maybe audio output as well ? I know for a fact that eDP is routed to DP_C which is non standard, almost all MXM laptop (except zbook 15/17 g2 and g3) have eDP routed to DP_D of the MXM connector. Meaning if the bios flash is sucessfull you'll need to run the card in switchable graphics mode to get a display on the internal display.
  16. JadeRover
    Correct, DP_D is the standard (zbook 17/15 g3 has it on DP_C as well). Yes, you want the 6VCJW one Look at pictures when buying, it's the only one with a white "3D" sticker on it. All the other cables won't work.
  17. JadeRover
    That's actually a 40 pin edp cable that is only for the RGB lcd (the connector isn't a standard iPEX that plugs into a 4K lcd for example). I made a post about the difference in the cables, see here : You want the "3D" cable that is standard 40 pin 4 lane edp that was made originally for the 120hz 1080p screen option. Keep in mind that using an eDP lcd will force the MXM card to output directly to the internal LCD, located on DP_D of the MXM connector. There is no mux for the iGPU. That means that if you are testng vbioses or cards that don't have eDP/DP on DP_D you'll get a black screen, external HDMI and even VGA should work all the time. EDIT : that's assuming you wan't to upgrade the lcd to a modern 40 pin eDP IPS lcd (1080p >60hz or resolution >1080p). Upgrading to 4K has been done by a few members of the forum, look up @TheQuentincc

    Hello, Clearly the card is in a dead short, judging by your pictures, the capacitors are burnt and shorted. The board layers look chared as well, meaning deep under the board layers the + and - are touching and shorting out. There is no way the card can turn on in this state as the main power rail is shorting out to ground. If you know professionals get them to diagnose the card, if it's a board layer short or a capacitor short on the main power rail the repair probability is actually pretty high. The GPU die and VRAM would not be affected by the damage (if I guessed correctly on board / capactor short). You need someone with the skill to dig trhough the board layers, rebuild them and install new capacitors. There are videos on youtube that explain this pretty well for desktop cards.

    Hi, yes the card will work in hybride mod, you'll loose a little bit of performance due to routing the display signal through the iGPU. I used a 1060M that had HDMi on DP_D (laptop booted with black screen in discrete GPU mode, booted fine in hybride mode and 1060M was recognized and used for games) Not sure the external display outputs will all work well, we'll have to look up the schematic of your model to make sure wich external display connections have a mux switch meaning the iGPU will run the external connections as well.
  20. JadeRover
    It has been discussed a few times, but be careful, Zbook 15 g2 routes it's internal eDP connector to DP_C of the MXM slot, you actually need to make sure your card outputs standard DP to DP_C so that the mod can work. I had a gtx 1060M on my zbook 17 g3 that only outputed HDMi on DP_C so it didn't work, even when trying a crap ton of different vbioses.

    Do you know any pascal editors ? For the display table definition it is pretty much universal for nvidia, these guys know how to do it. They used a hex editor, they talk about it in the forum posts.
  22. JadeRover
    Hi, Look here, these mac guys managed to edit the display tables on pascal Pxx00 MXM gpus iMac 2011 Maxwell and Pascal GPU upgrade | Page 21 | MacRumors Forums I personally tested their p3000 vbios and indeed the eDP is changed from port DP_D (stock vbios) to DP_C (to comply with the iMAC's MXM slot). I tried getting in contact with M0bil who seems to be the lead modder but no reply unfortunately He put up some links to this github saying it helped him mod the vbios but not sure how GitHub - envytools/envytools: Tools for people envious of nvidia's blob driver. I assume that display table modding should be the same for pascal and newer GPUs so there is hope if these modders tell you how to do it. The last heardle is that starting from pascal, nvidia vBios have a checksum lock that means vbios needs to be packed in a special way so that the security chip on the nvidia GPU runs the vbios (I tried manually editing power limits on a vbios and the p3000 and it wouldn't even post, even with 2 bytes being changed).

    Hello @GuitarG, super modding adventure, my hat off to you ! I have a question about making custom eDP cable, did you use sets of micro-coax cables for the individual wires ? Those with shielding around the data lines of the eDP data signals? I am asking this because I will attempt to extend a 40 pin eDP cable from a zbook 17 g5 so that it can go in to LCD panels that have the connector on the right side (looking from the back), by default, the zbook 17 g5 panels all have the connector on the left side (looking from the back). The current cable is too short and needs to be extended by 20 cms or so. There are some nice 4K 120hz 500 nits panels in my area and it would be a shame to miss out just because of a dumb lcd pannel connector placement. The fact that I want to push 4K 120Hz means I need very good signal integrity right ? Micro Coax seems impossible to solder by hand, the cables will be insanely close to each other and I can already see myself chasing shorts for hours 😧

    Pascal is signed with a Hash that changes each time you modify a single bit in the bios. These guys found a way to rebuild the hash that validates the check done by the falcon module on the nvidia core.
  25. JadeRover
    Actually I don't know about that, guys like on imac forums modder M0bile found ways to sign pascal vbioses to make them work with their iMacs. They modified the display table definitions, power limits, clocks, etc... iMac 2011 Maxwell and Pascal GPU upgrade | Page 21 | MacRumors Forums They haven't been clear on how they did it, supposedely using this : GitHub - envytools/envytools: Tools for people envious of nvidia's blob driver.
