Alienware M18x R1/R2 GTX 680M SLI Upgrade Information
As some of you may know, I had upgraded my M18x R1 to 7970M CrossFire, then GTX 680M SLI. For those considering an upgrade to GTX 680M SLI, congratulations on that decision.
Here is your shopping list, and what you need to know:
- GPU - the Dell GTX 680M is almost impossible to find. The 4GB Clevo version is easier to obtain and has twice the memory. It's fully compatible with the M18x R1 and R2.
- Heat Sinks - the M18x R1 NVIDIA heat sinks for the GTX 580M/675M are interchangeable parts. Left side: JW8P7 or 5G1VJ; and, Right side: Y3WC7 or Y48TK; Support Plates (2): 3MHHT
- SLI Bridge Cable - same part numbers as GTX 580M/675M. The item to order is GDMRG.
- Installation - same regardless of GPU. In addition to the Service Guide/Owner's Manual, this video should help. LINK
- Drivers - the NVDM.INF has to be modded to reflect the hardware ID of the 680M when installed in the M18x R1. See details below for instructions.
- vBIOS - in order to do any serious GPU overclocking or benching without throttling, you need a new vBIOS. The stock vBIOS has a dynamic clocking feature that sometimes impairs gaming or benching performance. You will need to get the appropriate one from outside of this forum.

Kudos to
DELL-Chris M for the above part numbers.

M18x R1 NVIDIA Driver Mod:
.
In order for the NVIDIA driver to recognize the GPU, you need to change at least one of the 11A0 (680M ID) strings to the M18x R1 hardware ID (048F) in each section shown below. I just choose the first hardware device ID string in each section that has 11A0 for this example... [NVIDIA_SetA_Devices.NTamd64.6.0], [NVIDIA_SetA_Devices.NTamd64.6.2], and [Strings] are the sections that require changes. There are 4 lines of code in each section with 11A0. In the example below, I changed the first line of code in each section, replacing 0550 with 048F. The original first line of code in each section is the hardware ID (0550) of the 680M when installed in the M18x R2 motherboard.
[NVIDIA_SetA_Devices.NTamd64.6.0] %NVIDIA_DEV.11A0.048F.1028% = Section187, PCI\VEN_10DE&DEV_11A0&SUBSYS_048F1028 %NVIDIA_DEV.11A0.0551.1028% = Section189, PCI\VEN_10DE&DEV_11A0&SUBSYS_05511028 %NVIDIA_DEV.11A0.057B.1028% = Section191, PCI\VEN_10DE&DEV_11A0&SUBSYS_057B1028 %NVIDIA_DEV.11A0.0580.1028% = Section192, PCI\VEN_10DE&DEV_11A0&SUBSYS_05801028 |
[NVIDIA_SetA_Devices.NTamd64.6.2] %NVIDIA_DEV.11A0.048F.1028% = Section187, PCI\VEN_10DE&DEV_11A0&SUBSYS_048F1028 %NVIDIA_DEV.11A0.0551.1028% = Section189, PCI\VEN_10DE&DEV_11A0&SUBSYS_05511028 %NVIDIA_DEV.11A0.057B.1028% = Section191, PCI\VEN_10DE&DEV_11A0&SUBSYS_057B1028 %NVIDIA_DEV.11A0.0580.1028% = Section192, PCI\VEN_10DE&DEV_11A0&SUBSYS_05801028 |
[Strings]
NVIDIA_DEV.11A0.048F.1028 = "NVIDIA GeForce GTX 680M"
NVIDIA_DEV.11A0.0551.1028 = "NVIDIA GeForce GTX 680M "
NVIDIA_DEV.11A0.057B.1028 = "NVIDIA GeForce GTX 680M "
NVIDIA_DEV.11A0.0580.1028 = "NVIDIA GeForce GTX 680M " |
Windows 8 users will need to reboot with Driver Signature Enforcement temporarily disabled to install the driver because Windows 8 does not "like" the modded INF and is too aggressive with preventing "unauthorized" driver installation.
.
(Note: To make the INF mod compatible with the M18x R1 and M18x R2, you can change the lines with 0580 to 048F instead of the first line with 0550. The NVDM.INF file has to be modded only because Dell/Alienware has not provided NVIDIA with the correct Hardware Device ID for the GTX 680M GPU when it is installed in the M18x R1 motherboard. This upgrade is 100% compatible with the M18x R1. However, NVIDIA refuses to include the correct code in the driver INF because it has not been "authorized" by Dell/Alienware.)

I came across this a few weeks ago, the guy(s) keep relisting more and more, so if you watch the item it will tell you when its relisted.
I also suspect dealing direct may save you money too ;)

card, heatsink, sli cable, possibly a new adaptor(330Watt) unless you already have the higher powered adaptor ...

Hi Jriess,
These are the part numbers for that list of parts for the M18x R2:
Graphics card Nvidia GTX 680m: CPCXD
Right side heatsink: Y48TK
Support plate: 3MHHT
SLI cable: GDMRG
You might be also missing the fan for the secondary card, you can check on that by opening the bottom cover and checking if the fan is there or not, if it's not there, then you have to buy the heatsink that comes with the fan instead of the heatsink alone:
Heatsink with Fan: Y48TK
And, if you have the 240W power supply, you need to buy the 330W:
330W PSU: XM3C3
I am trying to upgrade an m18x r1 from the gtx 460m to the 680m. I installed the Clevo and am having trouble with the .inf file changes. Can you tell me which folder the NVDM.inf file you are referring to is located as I am finding it in more than one location. Also, can you tell me what else I may be doing wrong? the system is not recognizing the video card.
I realize this is an old question and you probably have it sorted out already. In case you have not, or in case someone else raises the same question later on, I am responding.I am trying to upgrade an m18x r1 from the gtx 460m to the 680m.

The INF is in the "Display.Driver" folder within the NVIDIA display driver folders.
It depends on what you mean by not recognizing the video card. If it does not appear in the BIOS or in Device Manager as an unknown or generic video adapter, the GPU(s) might not be seated properly in the PCI-e slot(s).
However, if you mean that your system does not recognize the GPU when you are attempting to install the driver (they are detected by the BIOS/motherboard) this is normal. That's why you need to mod the INF file.
