Hi all,Here are the comprehensive details for upgrading my GT60 One-403US (MSI 9S7-16F311-403)All of the steps I took were based on posts in this thread primarily from Talon and Omega.The system was stock with an Nvidia GTX 680M (4GB) video cardwith Bios: E16F3IMS.50X and EC firmware 16F3EMS1 ver 5.05I purchased the new Clevo GTX 970M from R&J Technology as Talon describes.I also purchased some Arctic Silver 5 and some quality thermal pads.1.In my case Bios E16F3IMS.51X and EC firmware E16F3EMS1 VerT.18. My 51X version was modded by Svet from MSI to unlock all its BIOS options and to allow BLCK OCing.The modded bios and EC firmware upgrades are available with a donation to Svet. He is extremely helpful and provides very easy to follow and detailed documentation to update your bios and EC firmware. Make your donation here:You can see my request here..Svet was very prompt and extremely helpful, way more helpful than the small donation.2.The steps are relatively straight forward:a. Make a bootable Dos USB drive (many ways to do this... google search)I suggest you do this and test booting to it before you proceed as you may need to go into your existing bios and change it to legacy booting and also change boot order to start with a "USB drive" (it may list the name of your stick like it did for me)b. Use the tools Svet provided to move the new bios to the bootable stick and follow his instructions exactly to update the bios.c. update the EC firmware using winflash that is inside the provided archive (16F3.T18 in my case).3.In my case I now could set my memory timings (Svet explains this but it's very easy to find on your own).You can also set your multiplier (if you have an unlocked CPU). In my case I set memory timings and also chose default graphics to be the nVidia card and really didn't change any other options from default.a. Remove the power and battery from the unit and flip it over.b. There are 6 screws to remove and pop off the back plate.c. remove the single screw holding the fan in place and unplug the fan and remove it.In my unit the CPU and GPU are completely separated such that I could remove each separately. In some cases the heatsinks are intertwined and REQUIRE you to remove both the CPU and GPU heatsink.Since I was replacing the GPU I decided to also remove the CPU heatsink anyway just to re-apply new thermal compound.d. The GPU heatsink is held in place by 4 tension spring-loaded screws. They will not come out of the heatsink. Simply unscrew them in the reverse numbered order (notice numbers next to each screw).e. Gently lift The GPU heatsink off and out. We will be modding this slightly with a dremel to use with the new GPU so clean the thermal compound off and set it aside.f. Remove the single screw holding down the GPU and then gently pull up and out from the end of the video card and it will easily come out of it's slot (clean it up and sell it on ebay).a. I used a dremel with the small sanding/cutting disc to cut away a 1/4 inch soft raised aluminum section as defined in this image http://forum.notebookreview.com/attachments/img_4601_zps9017b824-jpg.117600/ Honestly you don't have to be that careful here... You just want that chunk gone and not grind down adjacent parts of the heatsink.b. Once happy with what was removed (5 minutes) then blow away any aluminum shavings from the heatsink with a can of air or your method of choice as long as you remove ALL aluminum particles.The new clevo card comes with an installed heatsink as well as a very annoying (practically glued on) heat spreader on the bottom side of the card which must be removed (it interferes with both fit and with the screws on the heatsink that you modified). Take note of where thermal pads are installed on the new card.a. Remove the Clevo heatsink by removing the four screws that hold it on and gently pull it off the GPU core.b. Clean off the GPU core with a few Q-tip swabs until clean.c. Remove the annoying heat spreader by using only thumb nail pressure against the parts of the spreader that come through the screw holes toward the top of the card. Press them until they are pushed back through the hole to about even with the card one at time (spreader will not come off yet). After going around the card and doing this at each hole the spreader will eventually start to loosen up and then one after another they will loosen enough to easily push / peel the spreader off. This takes about 5 minutes.d. Install your new GTX 970M by gently pushing the card into the GPU slot at a slight angel and once in all the way into the slot the card will easily sit down in line with the screw hole that holds the GPU in place.e. Replace the screw that holds the GPU in place and fasten tightly.f. Optional - gently place the modified original heatsink onto the card and carefully observe that the heatsink isn't hitting Anything when it's sitting in the right place on the GPU. Notice that it's a pretty tight fit so be careful and remove the heatsink for the next step.g. Apply quality thermal paste to the entire GPU core. Remember... less is more here... It is not necessary to have a thick coating and in fact putting too much thermal paste can be very detrimental. Just make sure the GPU core is entirely covered and you can smooth it out a bit with a Q-tip swab.h. Apply Thermal pads where necessary to guarantee contact of the larger chips with the heatsink. You can look at Talon's first post to see what it looks like or you can follow the same pad placement that Clevo used.i. Gently install the modified heatsink taking care to align the four install screws without dragging anything across the newly applied thermal paste and thermal pads. Screw the heatsink down in order (see numbers 1-4 right on the heatsink). It should be screwed down tight.j. Optional - if you had removed the CPU heatsink you will need to follow the same process but with three screws and again make sure that you applied a thin layer of thermal compound to the entire core.k. Plug in the fan, set it in the proper place (it sits easily) and replace the one screw that holds it down.l. Replace the 6 screws to install the back plate.m. Replace the notebook battery.n. flip over and plug in power and all your usb / sound / ethernet / HDMI / other cables.The next steps may vary depending on whether you are successful with the previous steps and dependent on the version of Windows you have. For this install we will assume Windows 8.1.a. Pray and hit the power button (Immediately listen/feel for the fan because if it isn't spinning but the machine is booting you should turn off the machine ASAP and check your work.)b. If your machine boots to windows you can immediately tell if it's using your card by looking at the power button light (orange if using Nvidia and blue if using Intel graphics).c. At this point your machine will either install the proper drivers (since we never actually uninstalled the Nvidia drivers you already had on the machine) or you will likely need to install Nvidia drivers.d. Check to see if the Nvidia Geforce experience is running in the taskbar. If it is then your drivers installed and you can check Device Manager to see if it's properly recognizing your new card and the Integrated Intel graphics as well).e. If drivers were not installed automatically then Download the latest nvidia drivers and "Try" to install them. It may fail but it will at least create the folders we will need for the next step. (nvidia typical puts the installation folder in c:

vidia)f. If the driver install fails create an inf file based on the post here....The name in that post is actually wrong... I named it nv_dispi.inf and I moved it tothe proper Display.Driver folder which is 5 levels deep from c:

vidiag. Disable driver signing (which is easy and in win 8.1 it is a temporary choice made prior to a reboot which will allow un-signed drivers to be installed ONLY in the next reboot.h. After your machine reboots you can browse to setup which is 4 levels deep from c:

vidia and right click on Setup and run as an Administrator.i. Drivers will install and will require a reboot.j. Reboot and ENJOY!
