GTX 1060/1070/1080 upgrade on m18x R2

A P5000 sli, how is that even possible! I thought quadros weren't sli compatible in mxm format.

 

I have no clue either, but that's what the lad has in their signature

 

They're probably not in SLI. You can boot with two in the P570WM but they will only be useful for compute tasks that can utilize both GPUs or games that support multiGPU (DX12).

If i find some time, i will open a thread.

 

Do you use something like DifferentSLI/SLIAuto?

 

No, because with DifferentSLIAuto it is not possible to use drivers above 388.71 and you get a massage about missing bridge.
And it is not really stable, so i had to find a different way.
After try and error i got it working.

 

How did you manage to get the P5000 in SLI then? I'm really curious! You definitely should make a thread or post about it

 

Was it software based or hardware based mod you had to do?

 

It is software based.I found a backdoor in the driver, but it only works for quadros.
I think i should not post it in any forum, because after that the door will be closed with the next Driver.

 

When I buy two quadro p5000 for my clevo, I would want to know lol .

I do rendering work in 3ds max and blender for university projects at the moment so it could be useful I guess?

If no one needs it you do not need to post it. I'm accepting that no problem
You are right about driver, if this backdoor grows in popularity it is over as it will be patched. Or you can use older drivers.

BTW freesync monitors are still working with nvidia gpu, that still hasn't been patched lol.

 

Very interesting....I wonder what the point of the SLI cables are then...? Just a cash grab? Would not surprise me. AMD has had XDMA crossfire forever

 

Sometimes the sli bridge needs more than the pci lanes to sync both gpu's together. It has been proven that sli can work without a bridge in some games when the BRIDGE IS TAKEN OFF MID GAME!

So it's kind of like a backup if the pci can't provide enough bandwidth for sli. It's good to have if you want sli all the time I guess and don't want driver issues.

 

Its likely XDMA SLI, as that seems the most likely given the circumstances.

 

You realize XDMA is an AMD-only proprietary technology, right?

 

Yes, but I used that in place instead of calling it PCIE SLI, I thought it would be easier to get the message across

 

SLI bridges than the original PCI express slots were capable of. With PCI-e 3.0 x16, it's not really an issue with most GPUs. However with high end cards like 2080Ti, Titan V etc, NVLink is needed.

Which display do you have in the P570WM?

 

120 Hz EDP Display.
Back to Topic:
I did some runs with different Clock rates:
https://www.3dmark.com/fs/16957347 +100 / +340 / 160 Watt
https://www.3dmark.com/fs/16957431 +140 / +400 / 170 Watt

The combi score is massive going down, but im not sure why. 330 Watt power adapter should be enough to handle it.
Could Optimus be the problem?

 

Optimus definitely causes scores to go down vs native eDP connection, but if both are running without or with, and you increased TDP/clocks, it might be throttling a slight bit

 

Optimus is the issue .... it sucks lol

 

What is Optimus?I just heard it,but don't know it.

Running the iGPU (Intel HD) as the primary display output, as it is able to translate the eDP of Pascal and newer GPU's into the Alienware 18's LVDS display
Because of this, increased latency is introduced, and performance is weakened

 

Thanks. I get it.
That is Why laptop get a higher FPS in game. after i switch it into PEG .

The best i get out with optimus.

Wow that is a very highly clocked i7. Congrats

 

Which 1070 were you using again?

 

Jesus how much added flex to reach 4.7ghz stable??

I could only hit 4.7Ghz only for CPU-Z validation, never for benchmark!

 

It is still the gecube 1070M.
Flex is at 25.

 

The blue or green PCB 1070?

 

The green one.
I´m waiting for some blue one. But that are desktop chips. I will see if i get them running.

 

Are the blue PCB's the actual desktop 1070's (1920 cores vs 2048 of the mobile) or are you saying they're the desktop TDP?

 

They have only 1920 cores and tdp depends on vbios.
But they have a sli connector.

 

Oh really? That puts me off them extremely compared to the MSI's then, but thank you. Also, it states their TDP is "rated" at 150w, but look how that went with the Eurofry 1070...

 

You have amazing 3940xm chip if you run 25 flex for 4.7 ghz 4 core

 

I dont think it is stable enough.
@Baddemichl your
Physics Score is almost same of my old 3920xm at 4200Mhz, so your cpu is throttling hard (I think its limiting itself at 4,3ghz at maximum)


look here at physics score, 4,7Ghz 3940xm VS 4,2Ghz 3920xm:

1070n vs 1060n (1% more points on your m18x r2)
https://www.3dmark.com/compare/fs/17020060/fs/12820620

1070n vs 970m (2.2% more pts. on your m18x r2)
https://www.3dmark.com/compare/fs/17020060/fs/11906628

 

Here's a good 4.7Ghz run:

I never said on all cores! I only needed 1 core at 4,7 for a better result in combi score.
Setting: 4,7/4,5/4,4/4,3
I didn´t really care about physic score.
I tried to get a good grafic and combi score.

 

Hey, did some of you managed to install a gtx 1080 in alienware 18 or m18 r2?

 

Or can you put 2 gtx1070 in sli, in 18 r2?

 

Since they cannot POST to the internal screen of the M18X/AW 18, it will not pass boot

 

One of the member here with Alienware 18 managed to run the 1070 without an internal screen plug in, and he was using PEG mode.

 

It was likely booting to the mDP, I've tested that to work on my M6700 to an extent
I'll see if I can find a display port screen and try and use my M18X R2 to boot to the mDP port instead of the internal screen

 

The only GTX 1080's that could even come close to fitting are simply too tall, and need extra power either from a external plug of demand more from the MXM slot than it can handle (look at the Zotac 1080 in the AW 17 R1 and M17X R4)
