p870dm-g 1070 sli upgrade teaser

this is already my 2nd build, it ain't going to be a complete laptop, instead I am build this one from leftovers to be a portable mining machine though I am planning to do some benchmarking with it, so that's is why the SLI cable is there

more pictures to follow.

 

Washers under the two slave GPU screws to not have cards bent under mounting pressure?

 

just not tightening the 2 mounting Slave screw till the end, going by the feeling!

 

Thermal stress and heatsink stress on that too, do be careful

 

thanks, I have left some space for the card to move, so no worries. this is my 2nd build already!

 

I see you're following through on my theory LOL

I'm concerned that that tab is getting warped. You got the heatsinks?

EDIT: I'll save SLI GPUs for a new model. I've done enough upgrading on my P870DM-G

 

whats its your overlap in the corner? finally it works?

thanks

 

works perfectly, on full load with some OC I get 70C on both GPU with fans on Overclock profile, which is actually not too loud!

while the time passes, I have already made a 3rd unit like this!

 

Ok my friend, you are my hero, thanks so much, where you get the videos cards with sli connector?

 

Nice work

 

ebay

i haven't mentioned it, but the mid frame has to be cut for the 2nd GPU to fit, pretty easy mod, but since its alloy, one needs to take it off the NB completely and thoroughly wash and dry it after.

 

nice job. do you still need the extra 330W to power both GPUs?

 

no, unless you want to do extreme benchmarks

 

Sweet. Are you using the stock 115W TDP or modding it?

stock with 180+ for the core and 400+ for the memory

 

should do an FS test to see how it scores.

 

I have i5 6600k there, so it will not score much overall.

 

How come your P870DM-G has an i5 6600k? Is it hard to find a 6700k?

But that's shouldn't matter because I just want to compare the graphics score from FS.

Nice project! I hope in the long run the twist of MXM board doesn't cause the BGA of the DIE to loose contact like it did for coolane's card.

Stock firmware would throttle the 6700K far too much to do any real benching...

 

Maybe look into a 1440p or 4K screen upgrade. I got a cable that I can sell

 

What it's the height of the each component, I mean thermals pads, screw washer?, it's possible get one schematic for assembly or small guide?

Thanks you

 

I have twisted the the HS instead of twisting the PCB!

As for the firmware... I am patiently waiting, haha!

 

read my initial post, it explains why

 

I will see if I can do one, basically I've used pads that came with the notebook, just cut them differently and spared a 3rd heatsink for extra pads.

 

Can you show some benchmark?

 

which one you want?

 

any benchmark that you have made...

now, its hard to find some 1070 with sli connector in eBay. upgradeyourlaptop and woodzstack666 dont have anything.

 

I will be keeping tabs on this thread as this will turn my default P870DM-G into a monster.

 

I haven't made any yet, so far just mining. it mines ~10$ a day, haha. so which benchmark do you want to see first?

 

Yeesh, running them flat out too.

 

well, if they will work at least a year, that would be like 4x profit from a card. thing is that these are semi-working old revision Vortex cards that fail to work with drivers higher than version 375.

so this is the only way to get my investments back, or possibly even make a profit

either way these were cheaper than the desktop version, that people usually use for mining, are now, so its win-win solution for me.

 

Fair enough, many happy hours of mining then

 

besides, I need to warm up my house's basement in the winter either way

 

you know the guy is here right @woodzstack

 

Didn't Eurocom release a standard size GTX 1070 Perfect for something like this?

 

without sli connector

 

Ah yes I see now... Thanks for pointing that out!

 

I'd get 2 1060s and run it like a mining rig if cryptocurrency is still a thing

 

* magically appears out of thin interweb space*

Yes, they have them, that means I have them if you have questions too.

Yup no SLI for you ! Sorry.

I'm placing an order for 80 RX Vega's for what I think is a miner going nuts.

 

Would a 1080 also work using this method as from this image the MSI 1080 Type 2 looks to be the same size

 

so there the stone is higher than at the ordinary card

 

The stone?

other radiators are necessary, they have various fastening and height of a stone

 

By stone he means GPU core, the mounting is different.

 

I see the image gotcha didnt notice that

10 Series offers great performance over 900 Series but compatibility is just garbage!

 

There's a few things that changed, dropped LVDS support - which is what kills it for your AW18, no nvidia reference design so manufacturers went designing their own cards specifically for their own laptops, as gecube found out the hard way you can't just slap a 1070 core on past reference 3.0b design and have it not blow up without proper design. And rx480 mxm was too busy being snapped up by miners (who don't care about compatibility beyond "can data be shuffled back and forth across a PCIe x1" link) to be widely available for notebook GPU upgrades, at $300us ea they could have been an awesome cost-positive (!!) 4K capable upgrade to p870dm 980m sli but it just never got past step 1

 

The no LVDS Support and the custom design for each card is terrible. Should be all reference design if at all possible to maximize capability with previous laptops.... These things are not cheap.
