Bought RTX 3080 Laptop GPU for my P775TM1-G.

[srs2236]

Hello!

 

So today I actually lost my sanity and ordered RTX 3080 Laptop GPU for my P775TM1-G.

 

To be honest I am very scared, every site even the seller mentions it doesn't work on any other laptop except the X170KM-G.

 

However, I checked both boards and they look identical, same pinout, same layout etc. The only difference is the screw placement, the default RTX 2080 heatsink doesn't fit, and I am aware of that. Already ordered a replacement from AliExpress with 30 series screw placement support.

 

BUT, I have a qustion someone from this forum might know the answer to. Is the VBIOS chip stored on the MXM card itself? Or the motherboard? Asking because if it is on the motherboard then I will definately need to reflash it right? Is the CH341 compatible with VBIOS chips?

 

I really, really hope it will work😭 Guys, please pray for my Clevo 😂. I couldn't for the life of me find any laptop other than the X170KM-G that was equipped with its RTX 3080 GPU.

 

Hopefully my P775TM1-G will manage... The display outputs are same, my laptop is also G-Sync version, same rated power 150W. But hopefully will be okay. Wondering about the VBIOS though, if anyone knows please let me know.

 

Of course there will be a follow up as I recieve it and test it so the people who are wondering about compatability will know the answer...😁

 

Thanks!

Do you have a page that shows a good photo of the RTX 3080 card that you bought?  (Someone can probably point out the vBIOS chip on the card itself, if it is present.)

This is an Ampere MXM card:
(I think its a 3070, but the layout will be the exact same for your 3080.)



The vBIOS chip should be the one circled in that picture. And yes, a CH341A will work with the chip if you need to flash a different one. It may take a few tries to get a good reading though.

Thanks! Well, In my opinion it means it should be plug and play but something tells me its not going to be the case... Have a bad feeling about this but I guess you don't know till you try it.

 

Also I actually just realised the VRM layout is actually a little bit different for the bottom 4 but it is not a big problem as I will make sure they make good contact with the heatsink and get adequate cooling.

 

Gosh this is going to be super stressful...

 

Altough one user from this forum claimed that someone from Germany has succesfully replaced P870TM GPU to RTX 3080 so I am still hopeful. Also makes me wonder why AliExpress would have produced RTX 30 Series compatible Heatsinks if the machine itself would not accept the card, but I guess Ali might advertise 30 Series just for higher sales tbh.

Aliexpress heatsink takes care of the physical mounting.

You could check with Eurocom vBIOS/BIOS wise

There's always Dsanke to further enhance compatibility

 

Good luck! Looking forward to the results!

I know this guy from Germany with 3080 in P870TM. I think the card works plug and play. If not, send me a pm.

quite the adventure! uve taken care of the physical aspects, now its about vbios / sbios / ec compatibility. u can definitely use ur programmer to flash the vbios chip, just make sure u have the right cable and clamp on hand that fits the chip 🙂

keep us updated!

Wow, this is quite the adventure, is the card from Ali Express?

Is there a link to his modification and what parts he got for it?

Asking for a P870TM friend of mine 😉

Hi!

 

No it is not. You can't even buy this card on AliExpress. It was bought from eBay. More specifically it was Eurocom Canada eBay account (upgradeyourlaptop).

 

It was put on bidding and in the end there was just me and one other bidder. I won it for a final price of 1140CAD or roughly 745GBP after conversion. And both are shipping included/total price paid.

 

That Eurocom Canada eBay account sells Clevo MXM gpu's (pretty much all of them) for around 1200GBP mark but every now and then they put some of them for bidding and the starting price is really good, like for example I think starting price for the 3080 was like 600 something GBP.

 

I couldn't really understand if it is a good deal or not but in the end just bought it anyway😅

 

It should arrive at end of July so some time around that I will post an update. Hopefully one with a happy ending😅😅😁

[1610ftw]

Happy ending? So it was from Asia after all 😄

 

Happy endings aside that is an excellent price - I have stopped checking their ebay account in recent times as all my laptops are where I want them to be as of now but to get a 3080 at that price is pretty stunning.

The card should be plug and play. You will still need driver inf mod.

Happy ending as in working in my laptop😃

 

I mean the card is being shipped from Canada, I don't know what you mean about Asia... Originated most probably but I think everything is😅

Inf driver mod is absolutely no sweat. Well let's hope it works 😁

This is what it seems like, same as with your heatsink 😄 Did you get the unified 3080 compatible heatsink that also offers water cooling capability or a different one?

It is basically the same version as the water cooling one, but just without the watercooling. Hopefully it will have a bit more copper mass but otherwise its completely identical to the water one. I assume so anyways. And yes, very and I mean VERY unified😂 definately can't run my CPU on 99c as it will straight away go to GPU aswell. Which of course is a big nono.

good thing about unified heatsinks is that u rarely have any loads that stress both the cpu and gpu the same. so dont worry about the cpu running hot under heavy load, in that situation ur gpu will be idle twiddling its thumbs, so u can use the gpu thermal mass to help out the cpu (and vice versa) 😉

Hello fellow MXM upgrader in the UK, i'm running a 3070 in my P870TM machine.

 

My heatsink is now unified but it makes water cooling simpler by having just one inlet and outlet.

 

Also due to being under water I have shunt modded my 3070, it's fairly easy to do if you can keep up with the heat.

[cylix]

Holy thats the ebay card i was watching aswell 😀. You got a really good price on it, i was thinking to bid but for Germany i needed to pay customs and VAT so in the end was to expensive. Good luck with it and keep us updated on the road to fit it in the 775 chassis.

Do you have a link to the heatsink you got or is it some kind of DIY heatsink?

Is it comparable in performance to the previous heatsink you had when the water cooling isn't active?

I got it through a russian guy in telegram so that might not be the best option now.

 

This heatsink is a little worse than the original, it could be a little better tbh mainly the slug for making contact to the CPU is not pure copper. Otherwise it's fine for now.

A shunt modded 3070 should give you about 3080 performance levels I guess? In any case I found a water cooling solution for the P870TM here:

https://www.cdrtd.com/products/laptop-water-cooled-air-cooled-integrated-radiator-for-clevo-p870tm-p870tm1-p870tm-g-gx10.html

 

It looks like this is different from what you got. The problem with all of these is not only the price itself but also shipping and customs and import VAT which is 19% over here:

 

It would be used with a P870TM with the old two piece cooling solution that came with early 6-Core processors so I guess even without water cooling that would be an upgrade.

 

And I would like to second what @jaybee83 says: Good to have you (back) here 👍

Here you go for performance with it cranked, thanks for the welcome.

 

Yeah I paid over 600 in import vat on the original laptop to the UK. But since it was a business expense I can't complain too much as I saved income tax and national insurance on it.
