Dell Releases A05 Bios: Fixes AMD 6990M Cold Boot Bug.

Recommended Posts

Dell has released an updated system bios for the M18x. The latest revision is A05 and it specifically addresses the overheating issue with 6990m video cards experienced during a "cold" boot (first boot). With this latest bios, the fans should spin up as the cards heat up and cool them down properly. Please use this thread to report your findings and experiences with A05.

If you have downloaded for the M18x a previous bios that has been unlocked, I have inquired at the great bios-mods website about fabricating a similar version for this bios so as to incorporate the fix that the bios A05 provides. Hang tight thank you Tech Inferno.

Thanks Marco oles! Great stuff on unlocking the new system bios.

Nice readme file LOL!

Hey guys,

Any ideas on how to OC or adjust the Multipliers on a 2820QM CPU?

Does the Unlocked System BIOS A05 unlock the multipliers setting?

Any other ways to adjust the Multipliers?

Cheers. :)

hey what's going on big chief! sorry you won't be able to adjust your multi with a non-xm. but you can adjust your power limit to help maintain your max multi for an indefinite amount of time. you'll see some gains but nothing major like with an xm chip.

Sup Chief, what happened to your ES CPU with unlocked multis?

The 2820QM got the multiplier locked, hardware-wise, no way to get this removed.

@chiefule Yeah exactly whats been said best bet is to raise the amps and watts way up it should maintain full 8thread turbo in most other than prime 95 / Linx/IBT

you want Primary Plane (amperage value) which is divisible by 8 to equal 1 watt... so stock is 97amps or 776 primary plane in the unlocked bios... or 0 if primary plane is 0 its equal to 776 or 97 amps also since 0 uses the fused value. So 168 amps and 168 watts is enough for 4.8-4.9 8thread wprime... so that should indicate you would never need that many amps... so try going any-wheres from 98-120 amps i suggest 108-112 to start and see from there. Now As amps are raised whatever the watt limit is you can see watt readings showing higher watts at peaks than when amps are set lower. So 99watt @ 97amp may show split second peaks around 105-108 watt but mostly stay close to mid and upper 90's... but leaving 99watts and going to how bout 108amp you will see 99watts more consistently and see higher peaks and they can last longer. So if you follow Widezu's method (http://forum.techinferno.com/throttlestop-discussion/1166-unlocking-tpl-all-cpus-m17x-r3-2920xm-overclocking-potential.html) of setting 99watts long limit on non-xm and use unlocked bios to raise amps that will be the overclocking you are looking for on that chip. Now once you have the 99watts long-term limit... and for now 108-112 amps set or (864-896 primary plane) test to be sure you aren't getting bsod under stress if its perhaps one ending in 000124 or 0000101 these are common for too much or not enough voltage.... in this case not enough so lower the amps by one amp or 8 primary plane till the system becomes stable with the 99 watt limit but maintains you turbo speeds almost indefinitely.... mention me if you have more concerns...

I have a few of those links in my SIG.

perhaps you should inquire that to Dell as i had similar issues and needed parts replaced. 8 beeps specifically just means a communication problem with the LCD but broken gpu or motherboard can effect that too... this bios fix only adjusts fans programming... you need to speak to Dell if you get no boot and 8 beeps ever...

      Hello guys so i bought a used alienware m17x r3 with hd 6870m on it, so when i was trying to boot well it goes to the windows 7 loading screen that says starting windows after that the screen turns white and goes to bsod saying atikmpag.sys
       
      also i attempt to switch my integrated gpu to my discrete card ( hd6870m)  and i wont switch at all 
       
      Responses are highly appreciated 
      Thank you in advance

      I have spent a little time in the past few days looking around this site. I would love for someone to point me in the right direction to a forum that has information that could help me out with my problem.
       
      I have a:
       
      Alienware M17XR3 
      Windows 7 Home Premium 64-bit
      Intel I7-2820QM 2.3
      Bios InsydeH20 Version 1.0 A12
      NVIDIA GeForce GTX 460M
      (4x) 4 GB Ram
      samsung 2.5" 256 SSD (SATA3.0Gbps)
       
      It has been an amazing machine for the last 10+ years. Minor issues, nothing that an Alien Respawn could not fix, till now! On battery power it works just perfect.  Then I plug it in and it's all OK until I try to do anything, and then the screen goes white. The screen sometimes goes yellow, sometimes blue, but mostly white screen. It will do nothing until I do a hard reset (holding the power button till it turns off and turn it back on) with the power unplugged.  If the power is not unplugged then it will go through boot up to windows swirling dots then go white again. If I plug it in and do nothing I can charge it, unplug and continue what i was doing. I have tried a lot of solutions bouncing around the internet, and thought I was having a DC Jack connection issue (replaced the ac/dc power adapter, then the motherboard). I get a better connection now but with the same white screen result. I stumbled into this forum and I'm hoping to find solutions to my issues.  Then upgrade like so many others have.
       
      Any ideas, comments or suggestions welcome.
       
      Thank you in advance!

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!

      Hello Guys this is my first post here!
       
      So my original post was this:
       
      "I don't even know if any active forum is out there on this laptop and on this issue, but after installing my new DHCG2 LTN173HT02 120hz display, I am unable to boot up on it. I do have a modded bios which the video setting is set to PEG, and just about read every forum about this but have not found a solution. I have tried resetting the bios, made sure the cable is plugged into the Edp port, and have made sure I have an UFEI Windows installation and legacy mode is turned off. I don't know what else to do and if anyone could help it would mean alot to me! "
       
      The reason it was not booting up on a pure UEFI environment is because my 660m did not have the GOP compliant driver vbios. You would need this in order to boot up in a pure UEFI environment which at the time I didn't know, and my fix was to stick to legacy. Any card before the 660m will most likely require this if you need to boot up in a pure UEFI environment. If you do not have this vbios driver while it is set to UEFI and plug in the 120hz lcd, it will beep 8 times and you will be forced to plug back in the 60hz display to change it back to legacy.
       
      This was the vbios that I can say worked for me and had the GOP compliant driver for the 660m
       
      https://www.techpowerup.com/vgabios/144032/144032
       
      ------------------------------------------------------------------
       
      These are the steps to upgrade from a normal 1600x900 60hz display to a 1920x1080 3D 120hz Display which is needed if you want to update your graphics card to a more modern one.
       
      I am making this guide because I felt frustrated that for this awesome computer, there aren't really any post in 2020 to upgrade the LCD panel to the 3D 120hz one. And The older posts I scavaged through really helped me little in doing this upgrade.
       
      Anyways lets begin
       
       
      1) If you have a stock AMD graphics card, and are wanting to install the 120hz display, then your journey ends here and you will have to upgrade to an NVIDIA graphics card to do so. If you have an NVIDIA, you may continue
       
      1a) ( Only if upgrading to pascal graphics card )Your NVIDIA card Needs to have a GOP compliant vbios  or else it will not let you select the UEFI option on the bios. This is needed because you need to set a UEFI environment before upgrading to a 1060/1070 Since these cards don't support legacy mode. This means you will need to flash a vbios onto your card that will allow you to boot on a UEFI Environment. You will need to verify first wether your card has a GOP compliant vbios by searching up your vbios version in GPU-Z. If you have a 660m that doesn't have this, then here is the link to that vbios that does. https://www.techpowerup.com/vgabios/144032/144032 I think that all of the Nvida 6XXm are not GOP driver compliant and need this but do not quote me.
       
      2) On the 60hz display, I would start by making sure that you have windows 10 installed or reinstall with UEFI support as it is needed if you are installing a pascal graphics card. If you have legacy mode enabled, and are not planning to upgrade to a pascal graphics card and keeping your old Nvidia 6XXM, then disregard this and head on to step 5 (although I would recommend to read everything)
       
      3) turn the laptop off and boot into the bios. In order to boot into the bios, spam the F2 key while it is turning on.
       
      4) Once in the bios, go to the Boot menu, and make sure to Disable "Secure Boot", Make sure that importantly if you converted over to a UEFI installation of windows, UEFI mode is chosen (UEFI  Environment will be needed for a pascal graphic card and legacy will not be compatible) then again, if you are on a legacy installation of windows 10, disregard this if you don't want to upgrade to a pascal graphics card.
       
      5) we can now start looking at the 120hz display. I bought mine on ebay with this seller https://www.ebay.com/itm/New-Dell-Alienware-M17X-R4-17-3-FHD-WLED-3D-V-M-LCD-Screen-DP-N-DHCG2-GN36T/273644412867?hash=item3fb67a5fc3:g:9A0AAOSw5AhcP1pw:sc:USPSPriority!32720!US!-1 (Just in case the link goes bad, this was the listing name"Alienware M17X R4 17.3" FHD WLED 3D V M LCD Screen DP/N DHCG2 GN36T"  with the screen model being  LTN173HT02 and Dell part number GN36T )
       
      6) Since my listing came with the video cables, I did not have to go out and look for the video cable. If yours did not come with the cables, You will also NEED to get the video cable it is required. the Dell Part number is N392W. I cannot stress enough This video cable is required and the 60hz's video cable CANNOT be used with the 120hz one or else you will brick your computer from what I read.
       
      7) Once it comes In, we can start to take apart the computer to Install our new display. I watched this video to remove the old 60hz and install the 120hz panel 
       
       
       
      8) Before I would remove the whole 60hz lcd panel, I would first make sure that you can boot on the 120hz panel. Notice that there is one connecter with screws on both sides right next to where the 60hz screen connecter is. Make sure that you put the 120hz one with the connector where screws are. This is known as the Edp port and cannot be confused with the LVDS port. Again, you want to plug the new 120hz display into the EDP port and unplug the 60hz one.
       
      9) If the installation was done correctly, then you should have no problem booting with the screen. if it is giving you 8 beeps, then just plug in the 60hz display, and navigate back to the bios to make sure everything is in order and refer back to steps 2-3. If you happen to be an advanced user like me and went ahead and installed a modded bios, then on the 60hz display make sure that the video setting is set to PEG. I dont think this is necessary to have a modded bios since the bios automatically changes the video setting when the 120hz display is detected and should be a last resort option to install a modded bios. I got my modded A12 bios from a guy in this forum named klem for 10 US dollars thorough paypal. Shoot him a message in the forum below.
       
       
      10) Once the new LCD is tested and you know you can boot up with no problems, go ahead and finish removing the old 60hz LCD and proceed to finish installing the 120hz LCD. And you are done. 
       
      A couple of words from my personal experience: When I installed the 120hz display, and booted up windows on it, and turned the computer off, it refused to turn on for some weird reason. I don't know why it would turn on when the AC and battery where on. regardless of what this was, I fixed it by Reseting the CMOS. If you don't know how to do this, do a quick google search and after turning it on i got 5 beeps which i then turned the computer off, and then turned it back on which the computer just reset itself and when it turned back on I was able to boot up into windows.
       
      This is the forum that I was able to find about upgrading the graphics card to the 1060.
       
      Anyways I hope I at least helped someone transform their computer! In 2020!
