First time upgrading mGPU

Recommended Posts

I'm going to be upgrading my Alienware M18x R1 with a GTX770m I purchased from ebay; 770m has a Dell P/N: HW6C9 for reference. I have a couple questions about performing this upgrade:

-Is the /unlocked/ version A05 bios necessary? I am receiving 8 beeps on startup with the dell factory A05 bios installed w/ the 770m
-Is a vBIOS flash required for basic functionality and driver installs? 
-If so, is there a link to a compatible vBIOS for this card, finally, a guide for installing the new vbios?

Any help is vastly appreciated, I've done some homework but I am new to upgrading MXM modules on laptops.

Yes, unlocked bios is a must.

After flashing the bios, you will need modded drivers for the 770m, and thats it.

The GPU shouldn't need a vBIOS flash to work, but doing so will allow you to tweak your settings more than without it. I recently upgraded my Alienware m15x to a 980m from Dell and it worked immediately. I could install drivers from Nvidia right away. You might find that you lack fan control, however. If that's the case, you can control the fans with a software such has Hwinfo. I use that myself.

      I've read a lot of conflicting posts about thermal pads for the CPU and GPU on the Alienware m15x. There are a lot of pictures out there detailing all of the different sized thermal pads that you need. In my experience, 1.5mm pads are perfect for everything on the Dell 980m and the 920xm. I was using 0.5mm pads at the time that I replaced both, so having the exact sizes was important. I think that I might have actually fried my 5850m in part due to not having thick enough thermal pads. I discovered that they had had not been making contact with the heatsink at all.
      I tried following the guide on techinferno and noticed that my gpu was actually bending (a lot) and certain areas weren't even making contact at all. I tried different layering of thermal pads through trial and error, looking for imprints of vrms and such. 1.5mm on everything worked the best.
      Some people are putting thermal pads on things that the manufacturers don't even put them on. I can't say what thicknesses are needed for these, but it will be more than 1.5mm.
      Anyway, I hope that this helps someone. I was using Arctic brand 0.5 thermal pads and stacking them in my testing. I have 1.5mm pads on the way now.

      Hey guys whats going on? I have an M17X R3, been running the 780M perfectly fine for about 7 months now. I've updated the driver once before, but it seems I'm having problems with all of the latest releases. Whats happening is when I download the latest driver, I run the setup so the 398.36 folder gets saved on my computer. Well thats what is NOT happening. Every time I run it, I see the folder pop up, but once the Nvidia downloader fails (as it should), the 398.36 folder disappears! I cant figure out how to make it stay there permanent! I've disabled driver signing and everything. Any suggestions?

      Hey guys, first post, but I thought I’d discuss my heatsink fan retrofit in my old M14x r1. 
       
      Old fan was loud and not very efficient: the air transfer rate was around 2 cfm (I’m assuming cubic feet per minute). Finally had enough and decided to swap out the crappy r1 fan/coughing pinwheel for a r2 fan (rated at 10.4cfm). 
       
      I found an old r2 heat sink on eBay (beware though that the heat sink for the r2 will NOT fit the gpu/cpu configuration for the r1. HOWEVER, the fan of the r2 heat sink it is attached to is a carbon copy fit into the r1 MoBo. A few philips head screws and a seal of good electric tape and BAM, you’ve got a significantly cooler and MUCH quieter intake fan in your old R1. 
       
      My CPU temps from before were around 87-88 max load in FSX, 65 for the GPU; bear in mind this is after a repaste. Now with the new fan, I’m not going over 77 degrees on the CPU, and the gpu stays around 58, all while being MUCH quiter. I’ll post pics of the walkthrough if anyone is interested.
       
       Just thought I’d share with all you fellow loonies trying to squeeze every last frame and degree out of our “portable toaster ovens with a screen and keyboard”.

      So I bought an older model M17xR3 with 6990 AMD GPU in it. When I turn on the PC the Screen blinks, image get crooked until I boot into the system. Also it won't load the video on YouTube. I can view the pictures on google just fine and load pages as well. Can anyone help me out ? Is it bad GPU or what should I do ?

      Here are my steps i made:
      1. I made a stresstest and my laptop shut down with a blackscreen (i just had 80degrees on one card and the other one had 35) and i wanted to get my Nvidia Cards back. I tried all with FN+F5, reinstalled windows, tried disabling Intel HD etc. etc. I had no chance to getting them back to Windows + BIOS. But it was working, all of it except the Nvidia Graphics Cards with A12 BIOS.
       
      2. My next solution was to check all my cables and positioning from all cards etc. But all was / is okay. SO if all is okay and i cant get it to work, i had just 1 possible solution, that was this unlocked BIOS for enabling GPU Settings.
       
      3. I made all the steps. All was working (got no Error during BIOS Update) and i restarted..... Bang. 1 Beep loop. After several attemps i cant get it to work again.
      I tried Mr. Fox workaround
       
          Turn the system off and disconnect the AC adapter
          Disconnect CMOS battery and system battery
          Do a power drain (press and hold power button 30 seconds)
          Remove all memory modules
          Reconnect AC adapter and power system on
          Let laptop beep until it turns itself off
          VERY QUICKLY, WHILE IT IS OFF, BUT BEFORE IT ATTEMPTS TO BOOT AND LIGHTS COME ON AGAIN, INSERT A MEMORY MODULE
          System will start to beep 5 times
          Power system off
          Reconnect CMOS battery and system battery
          Replace any panels removed for access to memory modules
          Done…
       
      (CMOS out, all RAM out, Battery off) but it is not working. If i made this i get 5 beeps again. But if i turn it on again i still get my 1 Beep..... CMOS in, all other out. drain it, then start it, i get a 2 beep loop, but it wont restart itself.
      So i dont know what to do to yet. i tried to put out CPU and put out both 980m. Then try to do the same process again but it wont restart itself. I got no Error or something else while flashing. I think it was Success- or Finished-Message at the end and after that i restarted.
       
      Yeah i dont know what to do to yet. i hope it is a easy solution because i dont know what to do without my "little brother".. :/
       
      So... 1. Problem: it wont restart itself the 2 beep loop for nvram Trick.
      2. If i replace the bios Chip, it should work again or is there still a problem with nvram?
       
      I would buy this Chip.
