Pascal GPUs with Dell Precision M6600

[Nowan]

Big discovery of experimenting. Got the chance to try my quadro p4000 from my m6700 to my m6600 cause I was inspecting my p4000 to insure that my thermal pad and paste is making contact while vram Half covered. it booted from bios to os with no issues and the best part is nvidia Optimus doesn’t switch off from powering down like the P106M does. As of now I couldn’t the gpu because it’s missing the option to use the nvidia processor instead of the intel gpu in the nvidia control cause of something to do with editing the hardware I’d and and drivers not sign now after editing. like the third try I did with P106M but with more updated driver with same issues. Not sure I need to edit something else then hardware I’d to enable the option to switch. I’ll continue testing tomorrow and find ways get gpu working to do some benchmarks.

You can sign the drivers yourself after doing modifications.

Update...  I was unable to get the option to use Nvidia gpu instead intel gpu on newer driver. has optimus been discontinued on newer drivers? same on older drivers the Nvidia  control panel does not start after installation instead run it manually by going to the folder. it has the option and select it to the gpu but no change after apply still use the intel gpu. i try using windows 7 to see any different on the gpu switch option control panel is there but still wont use the Nvidia gpu, after installation of Nvidia the aero is disable u cant reenable it. even tho the drivers are signed. 😓 i did one final test is disabling optimus bios and enable windows 10 startup sound to see if it boot with no issues without optimus and it successfully boot to windows 10 as it played startup sound. dell never create edp cable for 50pin edp screen (well for interposter for 10bit ips lvds screen ).

Just wanted to post an Update, since I am in the same situation. On the M6600 the card will change form 10DE 1BB8 15CD 1028 to 10DE 1BB7 14A1 1028 for some reason, after modifying the driver nvdmig.inf the driver will install. you will be able to see both cards installed. However they have their own discrete outputs, the intel card will have the internal and external monitors and a "Phantom monitor will be on the P4000". The only workaround I found is to disable the Intel video card on device manager and you will able to use the external monitor (HDMI in my case) with P4000 for games. if you want to use it on the internal display you will have to use mirror displays instead on Extended. I am still playing with Nvidia settings on the control pannel to see if I can modify the display settings for the Phantom Display.

 

Just in case anybody is in the same situation on 2024

Try this registry mod:

So it seems my M6600 might have a eDP display (N173HGE-E11).

 

Does this mean Optimus is permanently disabled like the newer M6700/M6800? Or is there some weird MUX switching going on?

 

My original plan was to put RTX 3000 in M6600 using Optimus. My M6800 has a LVDS display so I might just put the RTX 3000 in there. 

 

If it's eDP and directly connected I wonder if something like P4000 would work in M6600 with eDP display. 

[Aaron44126]

eDP bypasses the mux and is connected directly to the dGPU. You can’t use it with the iGPU. So, you can’t use Optimus, but also it shouldn’t be “required” if the dGPU supports eDP.

 

I think the only eDP panel sold in the M6600 was the 10-bit IPS display? They didn’t use it for the “regular” displays.

 

An easy way to check would be to see if there is an Optimus toggle present in BIOS setup. The option is removed if an eDP display is installed.

lp173wf3-slb1, requires the edp to lvds adapter and cables.

 

does rtx 3000 using the original vbios  or the hp rtx 3000 vbios that works on m6700?

 

 

i forgot how someone setup his hp mxm turing gpu on m6700 using edp or optimus? 

[ssj92]

Laptop is non-working for now so I can't check until I disassemble which connector it uses.

 

Service tag is: HJKPBT1

 

As far as I am aware, RTX 3000 does not support eDP. 

 

P4000 should though. 

 

Also, is there enough room for a slightly longer card to fit without any mods?

the RTX 3000 should work as the P4000 on the M6600 (it will only work on the external Monitor) as the internal is always attached to the Intel 3000.If you turn off Optimus the Laptop will not boot at all and the only way to turn Optimus back on is to put an older NVIDIA GPU (Kepler) to turn it back on. The P4000  will work fine on My M6800 with LDVS using Optimus.

Where did get you get that RTX 3000? The ones I had seen on Ebay will not fit as the screws are in the different position as the M6800 Heatsyncs (both AMD and NVIDIA).

 

PS> I tried the Registry entries that you recommended to no avail on the M6600. I ended using the P4000 on my M6800 and put the P3000 that I was using on the M6800 on the M6600 with exactly the same results.

You can turn Optimus back on by resetting the BIOS to default settings (just yank the coin cell battery).

The first gen RTX series works with EDP and had zero issues with my M6800 aside from needing to mod the heatsink so there is a chance it could work with your M6600. This card doesn't dump too much heat so it should be fine once everything is installed right.

@ssj92

Looking at your service tag, the stock screen has this part number : 93F76. Then, on parts people it points to this lcd : N173HGE-L11

And finally panelook confirms it's an lvds one, 40 pins, so you'll need to use optimus to get a modern card working

Interesting, when I checked the PN on Parts People I ended up on the E11 version which is eDP. If it's LVDS then I should be able to use RTX 3000 then using Optimus. Once it's up and running I will attempt this.

Interesting, I couldn't get my RTX 3000 to work on eDP but I have Adlink you have an HP one I am assuming.

Forgot to mention another thing to try....using a driver older than 425.XX such as 419.XX 

 

This worked for me on M18xR1 using RTX 5000 with Intel HD 3000

[ssj92]

Okay it was LVDS. 

 

I tried the RTX 3000 but Optimus no longer shows up in BIOS. Also it gets stuck at a black screen after the invalid system configuration error. 

 

I don't think these RTX 3000 from Adlink are as friendly with vBIOS but I guess I could try flashing a different vBIOS?

 

Does this mean it won't work in M6800 either since the Optimus option disappears in BIOS in M6600 with RTX 3000? 

 

I know on our Alienwares we can force Optimus mode regardless of GPU installed with unlocked BIOS. 

 

EDIT: Flashed Dell RTX 3000 vBIOS. Optimus now shows up. Installed windows but after installing nVidia drivers I keep getting system service exception bsod loop. Can boot fine into safe mode. 

[Nowan]

seems the RTX 3000 has potential to run on m6600 with some vbios that could work or either mess with vbios. 🤔
