Hi raven_ninety, I think you will need only flash "custom-modded-undervolted" GTX860M VideoBIOS, not System BIOS to undervolt your GFX card

Hey iTzZent, Just try this "nasty" trick: Install exact. cpu model & memory module(s) plus GFX as was in that last time where you can enter "normally" into system BIOS. Then switch notebook On / Off. After that unplug/remove one of installed memory modules and (or) try to reset EC as well by removing main and backup (RTC) battery plus unplug notebook from AC power, then hold power On/Off button for some seconds... Now check it by plugging only AC power and press On - If no go, continue with removing (or replace) an another memory module and try again... This will reset cpu System agent portion of motherboard BIOS booting process into "non-stucked" state so it will allows you to going into system BIOS again. If success, last step - In BIOS Load Optimized defaults & save changes. Then you can re-insert RTC battery.

Hi Mumak, to me it's EC and / or ME data area malfunction, since manufacturers "procedure" of how their devices internally communicate between each other is uncovered by any proper datasheet released to public, it's sometimes very risky to scan i2c buses. And suggestion? maybe complete BIOS reflash via external programmer or blind-FLASH and EC reset can help in this situation. Otherwise RMA

Hi Bugii, MSI nVidia 580M info: Device ID: 1211 Subvendor ID: 1462 Subsystem ID: 10A9 MSI 580M ORIGIN VBIOS from MSI GT783: http://gentechpcforums.com/Images/MSI/GT783/MSI_GT783-VBIOS.zip nVidia 580M Video Bios Collection: Video Bios Collection | techPowerUp

I'm unable to connect to mvktech site / forum as well, It says Server not found

Hi, @ideaalne, in terms of overall performance of CPU + GPU - to me it's way better configuration and sure more powerful than G75VW, but you must compare it in same resolution and setting if you wanna judge them in case of 3dm06...

Nope - Optimus @ mobile Kepler is addicted to BIOS support. if you put your Kepler card to IvyBridge notebook and try to disable Optimus thru nVidia Control Panel or via IvyBridge BIOS, and then put your card back to your GT780, that damned "switch-on" restriction thingy is back... :-/ it's not a permanent solution. I think a way via notebook BIOS Modding is "easiest" than back-engineering Kepler VideoBIOS, but - who knows? maybe someone is near in that VideoBIOS modding way about how to completely disable Optimus. BTW don't worry about your card I understand you, I know that Kepler family it's expensive just for testing - maybe someone of folks here @ techinferno have one bricked or burned unnecessarily @ home. I'm able to continue with modding / testing even with faulty Fermi / Kepler MXM card, because I don't need GFX output to check what I need to know...

hi @gregof45, From my point of view & experience so far - the main problem is Intel ME part of BIOS - that mobile Kepler family is shipped with "differently-coded" VideoBIOS than before in mobile Fermi (as your GTX570M) and this VideoBIOS simply wanna Optimus "ready" - enabled BIOS. About Flashing Modded BIOS with modded ME > without external ROM flash/er (to skip Intel ME flashing security descriptors) there is ATM no chance to change order of GFX initialization (this is the reason why you have no HDD activity and blank screen - your BIOS just stuck @ GFX initialization part of Booting process) and to update Intel ME to other than EXTERNAL - DEDICATED GPU state ONLY (which is default for MSI GT780 / 683 and compatible barebones too) To investigate every detail that we need to enable Kepler support on this and any other AMIBIOS "unsupported" platform I need any Kepler MXM board to test my progress in modding. I don't wanna sharing my completely modded BIOS due to possibly brick someone's notebook so so I'm stuck here without additional GFX for that. If anyone here of you guys could kindly provide me & send me (even bricked or non-functional / burned) MXM 570M/580M/670M/675M and/or any Kepler based MXM boards for testing, then I'm able to continue in developing in this modification and share it with us here @ techinferno. I'm only "one step from victory" in this process actually... Any interested ? - then please PM me for details. TY

@scaleop32 by quick looking into GX60 BootBlock code It's same as here: http://forum.techinferno.com/msi/1839-msi-g-series-unlocked-bios-41.html#post41293 just download the correct BIOS version for your GX60: - for Win8 preinstalled version: http://www.msi.com/service/download/bios-19987.html or http://www.msi.com/service/download/bios-19988.html and in this case rename E16FKAMS.508 (or E16FKAMS.708 for RAID model) to E16FKAMS.ROM - for non Win8: http://www.msi.com/service/download/bios-19387.html or http://www.msi.com/service/download/bios-19386.html and in this case rename E16FKAMS.105 (or E16FKAMS.305 for RAID model) to E16FKAMS.ROM GL

Hi, Just renaming a correct BIOS file to AMIBOOT.ROM is NOT suficcient, almost every OEM (any notebook manufacturer) will use their own naming for Recovery flash BIOS file... For your GX60, i think a correct rename of original BIOS file is: E16FKAMS.ROM GL

Hi, In your BIOS Advanced CPU PPM Configuration switch Config TDP Lock to DISABLED and try to set Long & Short Duration power limit to its max value, save & exit BIOS settings and try again in Intel XTU if your changes are "visible" .-)

Hi again, just try to reset the EC (Embedded controller) - it seems to hold corrupted data and prevent load BIOS after power-up, make sure to: - remove main battery - remove / disconnect internal CMOS backup battery - unplug AC adapter, then press and hold for a while (cca one minute) POWER button - after that plug AC adapter only and try again to recover your BIOS as was described before - at 1st power-up go into BIOS via Del button and select Load BIOS Defaults, then Exit and Save Settings GL

Hi @CACV, It's strange two cards in row hmm...your notebook is equipped with anti Short-circuit feature which you prevent to even power on your notebook if is something wrong with dedicated GFX, but you have CPU with integrated GFX so It's pretty normal that after restart is automatically switched to iGFX and you cannot find your bicked nVidia GFX in "Device Manager". To me your problem seems as lack of good thermal contact between VGA heatsink module and rest parts of VGA card (Other than VGA chip or memory chips). While checking new / upgrade card keep in mind that main VGA Chip temperature is not as critical as temperature of Voltage Regulator MOSFETs and Chokes. These small components on High-end VGA card are very hot under moderate / high GPU load. For example stable working Fermi / Kepler mxm card with properly applied thermal grease at GPU chip and precise installed thermal pads on VRs / Chokes easily hit 115~120 degrees Celsius at VR's, while theirs "working" temp max. is cca 150 degrees Celsius. So impropery inserted heatsink and/or lack of good thermal contact with VR's / Chokes can seriously brick one or more of VR's and will generate Short-circuit to MXM connector or burn main VGA chip if internal VR Controller misses switch off main power lane sufficiently fast to prevent additional VGA card / mainboard damage... Which is bad is that fact as you will need at least mini Infrared Thermometer Gun to monitor or diagnose your VGA card / components under normal notebook usage with disassembled bottom cover. Hope this help you to investigate what may be wrong and prevent possible problems with next card. Anyway please post your VGA photos in some high quality macro mode and we will see whats wrong...

Hello, If this is not too late to try, then i wish to help you with your troubles... So, to recover your msi gx740 (ms-1727) "back to life" (i assume you flashed correctly bootblock) you will try to: 1, download atm latest BIOS archive for your machine from MSI Global ? Download Center 2, extract that 1727_10f.zip file onto any folder you want and rename original bios file in that folder named E1727IMS.10F > E1727IMS.ROM 3, prepare one CD / DVD (even ReWritable one) and burn to ROOT of that CD / DVD only one file - your renamed BIOS file > E1727IMS.ROM 4, put this CD / DVD into your MSI 740 and before you press POWER ON button, hold Ctrl and Home or Ctrl and Fn and Home pressed till you will see blinking DVD access LED blinking 5, wait some time to recover your BIOS (you will be able see progress about flashin BIOS at your LCD screen) and welcome back your MSI... (Note: you may put that renamed file E1727IMS.ROM to USB stick too but some MSI machines only accept CD / DVD as recovery target medium) Good Luck
