Download the BIOS from the OP or the BIOS from my post which is basically the same thing but with updated microcode (one or two pages ago), and flash it normally (i.e. run the .exe after unzipping). If you are flashing the BIOS from my post, you will need to download the BIOS from OP, delete the .rom, rename one of the files from my BIOS to QIWY3207.rom and run the .exe. If you can an error about the version. open platform.ini in notepad and change RESSEN to RESSDIS. I believe it's located in 3rd/4th line.

You can flash v8.0x from v2.0x without bricking. As stated in the OP, the EC will not be updated and this could cause unusual behavior in certain situations. Search for nicolas' post in this thread on how he did this, I believe he also flashed 8.0x EC as well.

If that's the case, I think a little ME FW modification can offer a solution. Sorry for the size, but look at the highlighted section & other options for the mPCIe configs.

2.08... you mean the one I posted? Either way, you can revert/flash any BIOS via BIOS recovery. IMO and IME, this is better than flashing in Windows or DOS. BTW, all Y580s have HM76 chipset, therefore it'll be nearly impossible to OC the CPU, regardless of what mods you do on ME FW, BIOS, etc. because apparently the HM76 is incapable of overclocking (CPU) and is limited at the hardware level. However please come forward or PM me if you have figured this out. You can still flash my BIOS but the only real benefit of it will be updated microcode.

I just recently bought a PE4C, and an extra mPCIe->HDMI connector for x2 link. The PE4C itself is functional, but I cannot get the x2 link to work. I have two mPCIe slots in my laptop, and have connected both to the HDMI ports on the PE4C adapter, GPU-Z still reports only a x1 link, Gen 2. I've tried switching the HDMI cables, and reinstalling drivers without success. Is there something else I need to do for the x2 link? Should my integrated Intel HD 4000 be disabled in BIOS or should it be in a state where the OS will detect it, but not selected as the main GPU? I have a GTX 970 & Lenovo Y580 w/ unlocked BIOS.

i lied, im not confused

Low as in 1k less than the win 8.1, anything beyond 8k still seems high to me LOL; before eGPU, I was getting ~3.8 (stable) -4ks (lucky if I made it through the 2nd test w/o a GPU hang..) on my pos/probably-dead 660m. Although, I did have fun upping it to 2.212 volts. Thanks for the quick reply, I will trust your opinion.

I did a lot of googling, finding mixed answers. 1. Anyone else finding low benches, specifically 3DM11, on Windows 10 Tech preview? I have a 3920XM @ stock () & GTX 970 via PE4L (swapping w/ PE4C tomorrow). I get max 12642 (14910 GPU score) on Win 8.1, and 11800-12000 on Win 10. Is this because of funky OS/driver/OS-incompatibilities or is my install corrupt (I have done some things.... but it's been like this since before that)? These benches are both of similar clocked setups. 2. Is it better to have my integrated gpu, intel HD 4000 completely disabled, along with discrete GPU, or better to have the HD 4000 initialized first (and then have it crash/disabled in device manager for some odd reason after boot)? My external monitor is connected via eGPU hdmi. -Thanks

Okay, ignore my last post, I think I found an alternative to allow HM76 users access to ICC lib (rather, more options to try). I created and flash an ME FW and tried to trick ME into recognizing my HM76 as an HM77 by changing it near the top. Also, I used the wizard this time (f9), and chose the ME8_1.5M_PreProduction (from the zip, I don't remember if it's from the OP or somewhere else..) because I found out it also has the necessary bit which enables manufacturing mode. Having this enabled give you more access to the FOVS (from fpt -FOVS or fpt -CFGGEN) as well as the VARS. For example, if I would try to obtain the MEBxpassword *before,* when mfg was disabled, it would return some error. Now, as you can see below, it gives you the value. Also, have read some forums posts where people were able to enter MEBx setup by hitting CTRL+P during POST, and disabling Intel ME Firmware (it doesn't actually disable, but as close as you can get). If you are able to do this, then the BIOS will be unable able to send the EOP signal to ME, therefore allowing successful use of the cct sl command (hypothesis) with Clock Commander Tool (attempts to unlock all ICC registers). I don't know if they were on 1.5mb or 5mb versions. Can someone help me unlock ICC? I can't enter MEBx setup via CTRL+P, also can't get ME FW to think my HM76 is a HM77.

For anyone who wants it, I have uploaded a BIOS based on svl7's 2.07 version with the following changes: Updated microcode from revision 0x15 (from ~2012)-> 0x1B (from ~2014) Modified ME firmware which can possibly unlock and allow the ability to overclock your CPU by increasing the BCLK or multipliers depending on what CPU you have. If you have 36xxQM CPU, then probably only base clock. *NEW* More options available in the Advanced->Extended ICC tab. However the only working setting is for choosing ICC Profile and depending on if you changed your ME FW to either allow more than one profile and/or you've disabled the soft strap under PCH Strap 10, then most likely the profile setting will not stick after POST and will be overridden by "OEM setting." NOTE: The DIV_1S/DIV_2/DIV_xx/etc settings are not functional at this time. If you try to go into its sub-menu, your bios will freeze up (Don't worry, nothing should break). Just hit alt+ctrl+del to restart, or manually the push power button if for some reason you don't like shortcuts. [*]*NEW* The last two settings without descriptions which are set to zero by default, I have no F$%ing idea what they are supposed to do. If I had to guess, the first one is supposed to just display "Libary disabled after End Of Post" and I have no idea for the second. This is still a work in progress, and I am hesitant to call this an experimental beta because the amount of risk in flashing this is the same as flashing svl7's version; I personally flash/test/explore all BIOS files on my y580 (stock BIOS = v2.0x) before uploading. If you want me to do a 8.0x version, pm me; if enough ppl pm me I will just upload here How to flash (yes, it is different!) Disclaimer: Flash at your own risk! I am not responsible for your bricked laptops. I will do my best to help you out but that is it! Format a FAT32 USB, and extract the contents of the zip to it. WARNING: The .rom files located in the zip are the most common names required for y580 to recognize it during bios recovery. If you want to be sure, download andy's bios tool, choose your (not mine) bios, open it in the tool and it should pop up and tell you something like QIWY3.b*? If it says QIWY3.b* then you don't have to rename. Uninstall Intel XTU if you have it installed. Power down the laptop, remove the battery, and unplug the charger from the wall.Now, with the other end of the charger still plugged in, press and hold the power button for about 10-15 seconds (this is the proper way to do cold boot fyi). Unplug the charger from laptop, plug wall side in. Plug USB in the port closest to where you would normally plug the charger in. Now, while holding the Fn + b keys on your laptop, plug in your laptop and immediately push power button. If your usb has an LED indicator for read/write activity, and after ~5-8 seconds it doesn't start blinking then there's 2 possibilities; A: incorrect filename and your BIOS cannot recognize. B: USB partition became corrupted (happened to me). In any case, you should know how to troubleshoot. If you are having trouble entering recovery mode, make sure you are cold booting. When it starts to beep, you can let go. It'll beep 15+ times, and restart itself eventually. After all of that, you can enter bios to see the microcode @ 0x1B. You can now install Intel XTU, and might have the base clock un-greyed. I am currently trying to find out how to allow this for everyone and all CPUs with fcpga988 socket but this is best i can do as of now. Let me know if you have more than 11 ICC registers unlocked. You can check with Intel's Clock Commander Tool (CCT). For convenience, I uploaded it below. Just open elevated cmd prompt, type cct rrd. Also if you have been able removing some CPU OCing limits, please let me know via pm or reply. I am trying to get this to work for my 3920XM, but it hasn't gained any extra unlockability, just as limited as 3610QM except being able to decrease turbo multis. This worked for my friend who also has a Y580, but is a win 8 version... Blowntaha's mod.zip Clock Commander Tool.zip

Does anybody know of a way to run CCT.efi before EOP (End of POST signal from BIOS) because according whenever I try cct sl which tries to unlock all ICC registers, it gives me an error saying it's not supported after​ EOP..

I re-flashed a third time, and then dumping my me bios to verify in FITC. I can 100% positively say that the settings match the ones in the me fw you uploaded for me. However everything still appears locked. I noticed a 'Clock Commander Tool' inside the zip of the ME tools, could that possibly help troubleshoot? I've attached my newest, corrected, current ME dump. OCME3DMP.zip

Woohoo! The BIOS recovery worked, at least as far as I can tell. MEINFO is showing read/write access as enabled, although my ME re-flash firmware is disabled in BIOS. It also seemed to reset all of my NVRAM vars I fiddled with which I've read in numerous places emphasizing that it does not reset NVMRAM. I ran MEINFO right after the first (me-only) flashing, it gave me an error Error 9459: Internal error (Could not determine FW features information) I also realized I forgot I didn't do a cold boot so I reflashed the one you uploaded (used one I modified for first one), cold booted, and will edit this to report back. EDIT: everything still seems locked, going to try once more, but not reflash because I forgot I modified full BIOS.rom and added it in there... /facepalm EDIT 2: Okay.... So I went into BIOS recovery, and it successfully flashed the modified ME FW, I verified this by fpt -me -d -me.bin and checking if the proper bits in hex edit were set. Also, fpt -DUMPLOCK shows which is what they should be if they are in fact unlocked. I completed all of this error-free (rather, I didn't repeat anything that would produce errors, such as running meinfo, and reflashing unnecessary firmware). After finally unlocking flash descriptor, XTU still does not unlock my multipliers, nor does throttlestop. Attached is my current ME FW dump. All help is appreciated (it really is). EDIT3: Just opened dump in fitc and saw wrong settings, gonna retry me.zip

I was able to flash and dump freely when I first started meddlig in ME FW. I think I may have flashed either a bugged/corrupted FW, or one with certain settings that may have messed something up. Would it be possible for me to mod a full bios .rom, enter BIOS recovery by hitting the required keys while powering on laptop to enter recovery mode and let it flash that way? Would that flash the ME as well? FYI, the pic I posted earlier was of one after successfully flashing. But now, I can't even dump. If I'm unable to unlock descriptor, I think I might just buy an spi programmer... How do I know which one to get and if it will be compatible?

Wait a second, if that is the case then how was I able to produce this dump? I took a picture after the second time flashing, thinking that something went wrong after the first time. If I was able to read the ME FW to make a dump, and able to flash it (proof below), why am I unable to now? & If I do a full bios flash, modding the bios .bin by replacing the old me fw with a modified one (in hex edit), setting MEUPdate=1 in platform.ini, might that work? Also, I just dumped my descriptor to see whether or not I'd be able to, and I was able to. Is there something I could do with that dump to enable read/write on ME?

XTU: EDIT: So you just short the pins circled from the first pic? & would someone mind telling/showing the best way to do that (best = easiest)? -Thanks

lenovo sucks, everything so locked down and difficult to mod.. How do i add a pinmode on audio chip to a bios?

EDIT: So, you're saying I can't do what this guide does? The brief tldr; version, he finds ME bios in hex editor (which has main bios open) highlights the ME FW portion and saves it as dump.bin. Opens it FITC, mods it, open in hex, copy and pastes over old. I actually did all of this and have it ready to flash, only I wanted to come here first and make sure I'm not missing something that I shouldn't do this. Problem is when I copy and paste ME from bios in hex and save, it is 1532 KB, then after modifying it and rebuilding it, and reopening it to get the smaller parts, I get no file which is 1532 KB. Closest sized file is 1396 KB which is not the same length in hex editor meaning some random text will be before or after the me fw data so.... could that cause problems?

How do I flash under EFI using the fpt.efi? Would that maybe make a difference? Btw, renamed BlowntahaOc -> ocme in case you're wondering if I flashed the correct image; I just tried again in Windows as well with no success. I think there might be a setting in the FW image that makes or breaks my flash because sometimes I am able to flash and other times I am not able. Do you think you could upload the full image for me to try? Or could it be that my 3920XM version is somehow interfering?

So... I copied all of the highlighted settings from OP, flashed the full ~6mb image, and nothing has changed aside from buggy XTU and inability to reinstall IMEI drivers which I need is necessary for XTU to work.. I was able to reflash just the ME portion, however, everything is still the same. I reinstalled XTU each time. Did all flashing in DOS. Can someone help me out? dump.zip

I did, I guess svl7 has been busy or has higher priorities :[

EDIT: oops double post

Which bios version? you modified it starting from the stock bios or svl7's bios? What exactly did you change when you.... "cuted" it? Also, I have one request; do you think you can mod my bios so that I can overclock cpu? I replaced the 3610QM with 3920XM. But there are only two bios options in advanced->Extended ICC->Lock Registers->Lock Static registers only / Lock All registers... There is no Disabled or any other option to remove the lock from my unlocked 3920XM cpu. I am currently using svl7's v2.07 unlocked bios.

Hello, I have a Y580, and my BIOS mod request is for the extended ICC section under Advanced in my v2.07 BIOS to become unlocked for unlocked CPUs. I have a 3920XM which is an unlocked CPU, however I am unable to increase its multipliers (I can decrease them but where's the fun in that..). I posted the following information in order of the quote's questions (first quote bullet = first bullet, etc). You did already modify the current BIOS, however, the extended ICC is still locked, even after swapping a locked CPU (3610QM) with an unlocked CPU (3920XM). I agree. If by stock firmware, you mean BIOS, then is it alright if I upload a BIOS that you have modded? I also have the stock BIOS version as well. Here it is. BiosBackup.zip Stock BIOS is 2.0x, and since the risk of brick in flashing v8.0x on top of 2.0x is high, I have provided files for the 2.0x BIOS, unless of course you think it will be easier for you and better for me to work with v8.0x. In case it matters, I did the biosbackup in Windows 10 x64 (did the flashChk in DOS per instructions). Thank you for offering such a service, and I hope you will be able to work on it soon (: FLASHGEN.zip
