P770DM + eGPU?

Dear NR Forum,

I recently picked up a P770DM (Eurocom) with a 6700k and 980m. I was hoping to upgrade the GPU to a GTX 1080 (or ti). Assuming I can't replace the 980m with a 1080 is there a way to plug in an eGPU this laptop? I believe it has thunderbolt 3.

Thank you

 

of course you can upgrade to 1080.

also TI doesn't exist for ntoebooks yet to my knowledge

 

I heard the 1080 mxm card is physically larger than the 980m

 

Yeah they are slightly thicker, a little modding should do the trick, if you don't want to mod ur case and can settle on a GTX 1070 then you can get this one:

900 US for a GTX 1070....

an external GPU and 1080/ti is surely the same price? Any idea whether that would work?

eGPU will bottleneck the 1080 as far as I know hard enough to make it on "GTX 1060" levels (maybe even worse). So honestly i'd settle for a MXM 1070 from the site posted by sicily. I don't think eGPU is the way to go here especially whe sconsidering something on GTX 1070 / GTX 1080 levels performance.

 

4x lanes through the chipset really hurts anything above a 1060 really.

 

So external GPU is a no go? I suppose an internal GTX 1070 is the next best thing? What type of modification will I need to go through for a GTX 1080?

 

I don't know your case, but a little bit of dremel cutting will do. Also you need a bigger PSU I think.

 

For now there is not much reason to really fight it, next gen would offer more of a boost for the effort most likely if it works.

 

I also don't suppose if any of you know about a bios update for this laptop? Something that would allow me to overclock the cpu? As of now there is some stock bios that is terrible. XTU doesn't work very well. CPU seems to be stuck at 4ghz.

 

PREMA BIOS, if you can get your hands on it. The Clevo BIOS plays things very close to the vest and remains minimalist in its options.

 

Any idea how I might go about acquiring this BIOS? I hear Prema works on donations. I wouldn't mind paying Prema for his/her efforts.

Do you work for free?
Premamod works hard for his bios

 

Not sure what you're insinuating.

I asked how I get his BIOS mod for the P770DM-G.

 

Just PM me and bring a lot of patience. I go through requests like every other week or so and try to help wherever I can...

 

Do you have any idea what you are talking about and which model ?
The Clevo 1080 can only be used after extensive modding, and not just physical modding, but it needs rewiring to even power up. And when i say rewiring not only on card, but on the MXM port as well.

Please get your facts straight before confirming things like this, OP might just go ahead and buy a $1200 paperweight that he cant use.

Here's to your bottleneck claims : http://forum.notebookreview.com/thr...-g-gtx1080-tb3-hdk-pe4c-v4-1-m-2-ngff.796773/

 

MSI 1070 should be plug and play, provided you mod the chasis/frame accordingly. Also you might need Prema's BIOS to get it functioning properly.

 

You do need to look at gaming FPS.

 

It doesn't. Only TB to PCI/e conversion (except possibly professional workloads)

It won't work. Please don't tell people it will. Only thing that might fit there is a MSI 1070N and that still will not fit properly.

 

TB is PCI-E, it's kind of built into the standard.

 

The conversion from the Thunderbolt standard to PCI/e adds latency that hinders GPUs 1060 and above. Use a DIY M.2 NGFF solution or use a proprietary solution like the AW AGA or the MSI GS30 you once had, and that problem goes away. The PCI/e 3.0 x4 connection in itself is not the issue. @tgipier has run benchmarks and played games on a Titan X P for me at PCI/e 1.1 x16 (so about 3.0 x4) and noticed margin-of-error results compared to PCI/e 3.0 x16, as well as @bloodhawk has tested with his own DIY solution.

 

Now that's interesting, I didn't know they made ones that can be powered though the M.2 port. How is the stability in games on M.2?

I was actually talking about a Clevo GTX 1080 which apprently isn't released yet. Eurocom wrote in one of our threads (keeping mxm alive or so) that they would release a GTX 1070, RX 580 and the GTX 1080, which all should have the standard MXM factor and which won't need any kind of extra power source. It seems that only the RX 580 and the GTX 1070 have been released thus far.

 

Everything works just fine in and out of games on both the solutions. But as stated earlier, to have it properly work, Prema's BIOS is somewhat of a necessity.

 

I mean you tried TB3 and it did bottleneck according to the linked post. What do you mean with Prema Bios is somewhat needed? Could you explain?

 

Yes, i played a lot of DOTA2 . CSGO, Doom , Overwatch etc. There is obviously a overhead compared to dedicated PCIe slots, and that is due to the TB3 to PCIe signal conversion. Also as i stated in that thread, using a 1080 is not worth it, however a 1080Ti definitely works much better. Albeit there will be slightly increased latency.
Prema BIOS will let you control PCIe hot plugging on the BIOS level, which is pretty much a must with the way Nvidia drivers are right now,with older drivers it wasnt needed, but with the newer drivers, without using an extensive driver installation / un-installation process people will run into a Code 43 error. With the hot plugging options, non of that is needed.
All of this has been discussed in that thread IIRC.

 

Thanks for the info! Appreciated.

 

GS30 was a x16 link straight to the CPU. I agree the 4x link bandwidth itself is not so much of an issue (though through the chipset that does get shared with everything else).

 

It does share, but the performance dip from TB3 that is nonexistent with M.2 NGFF means that the chipset isn't a problem in itself

I think open world games where you are streaming content will have a bit of an issue with that, but we do need a direct on die link to kill that latency dead and not restrict anything else.

Once we have that then external will have a market.

 

Hi Prema,

I started a conversation with you here on notebookreview forums. I assume this is the same as a PM!

Looking forward to hearing from you.

 

Yes, conversation = PM.
