The hopeful of keeping MXM 3.0b alive thread!

Just a single 980m I still have my old 970m that it came with.

 

I'm talking about this

http://forum.notebookreview.com/threads/successful-mxm-gpu-upgraded-laptops.805136/

 

That is the laptop model I have, just with a single 980m. Looking to upgrade, if AMD drops something.

 

Could someone email an AMD contact and let them know about this big emerging market.

 

You are welcome! An updated version might come out later.

 

Any chance we will see a version that can be flashed without using the external programmer?

 

reminds me a lot of the Silverstone unit that Linus posted a video about from Comtex

 

I'm sure Tul, GeCube and other MXM card Makers are inquiring

 

Their tool can't fix that, it only mods the mobile Pascal gpu vbios. You still need to use a modded version of nvflash and so far it's still uncrackable.

Besides, using a programmer will make ya feel so hax0r.

Have a link to the programmer/tools I need to get? I am willing to give this a crack.

 

It's been posted here, you just need to go back a few posts.

Most of the stuff you need can be had on ebay like an SP16-B programmer, an SOIC8 clip adapter. You can use nvflash to find out what chip is being used to store the vbios so you can buy a programmer that supports that chip.

Apparently a 1.8v adapter is recommended so you dont blow out the chip. Mr. Fox let me know about that one. Ive got my programmer coming too. Im hopeful of getting 20k graphics score.

 

So is there anywhere reputable to buy the Gecube 1070 MXM so far? I tried emailing Gecube to inquire and haven't heard anything back.

 

As crazy as it sounds i recommend just buying a zbox 1070. The card works perfectly and is well made. It can be purchased for 900 to 1000 barebones which is expensive but is close to the going rate on these cards

 

The programmer can auto detect the chip voltage. Nvflash will tell you your vbios chip manufacturer and its voltage range.

I got a minipro tl866a dont know if its the one you mean but im just gonna play it safe apparently the voltage range on that unit is 3.3v to 5.4v.

 

There was a poster over at the voltground forums that used that model and it detected and flashed fine for them so you should be fine. They even had the same chip maker as me so it should be good. I bought the same programmer that @Coolane has so it should be straightforward enough: wipe, flash, verify, test.

Good to know. I didnt want to take any chances

 

Here's the post.

You can tell from the pics that flashing is successful.

I believe you. I was just stating what i was told by a guy who knows what he is talking about. It is very likely it would be perfectly fine without the adapter.

 

It's good to back it up with evidence to cement your confidence.

interesting to see a clevo vbios (i wonder if they interchangeable?) having the same TDP as all other 1070 MXMs: 115W.

 

As of right now, i do not recommend buying one, mostly because they haven't fixed the MOS problem yet.
Many of the tested card ran Stress test just fine, but GPU MOS got burnt right after 5mins of Witcher3 on Ultra settings.

It is possible to use CH341A (cheap programmer + clip) to flash 1.8V chip.
You just need to choose a lower voltage+ same capacity chip, don't have to be the same model.
For example MSI 1070 uses MX25U8033E(1.8V) , but you can simply select
MX25V8006E(2.5V). Choosing a 3.3V chip WONT WORK.
It has been proven to work in GZUT's OnePro Programmer(probably CH341A model) with just the clip itself.

 

Fair enough. I'm still waiting for my programmer to just ship from the seller.

 

Ya, it is simpler to just get an expensive one, most of them comes with better functions and software.
i have a GZUT onepro, i only used it a few times to revive dead graphic cards that i killed with bad vbios, and the ones that just do not boot up my screen. (it only costed me 7USD in total)
CH341A is more for people who knows what they are doing, or people who do not want to spend too much on a programmer that you might only use only once

 

Probably not . Making a modified vBIOS(Pascal) that can be flashable directly through official nvflash is difficult at this time.

 

Ive tried to modify my vbios using the pascal tweaker but anytime i flash a modded vbios on to my card using the programmer it does not work. Reflashing to the stock version makes it run like normal though. I have an alienware 17r1 with a zotac 1070. It may be that the pascal tweaker isnt compatible with my laptop but i hope im able to get it to work. I dont know if i will be able to if anyone has any suggestions im open to it.

 

Do you think you can send me a link with the stock vbios that you are using?
Also, what symptom does it have of not working? And what TDP values did you use?

 

The vbios is a stock msi 1070 vbios. The laptop hangs with no post and no lighting of the display but does not turn off it just stays on with a blank screen and it is not sending a display to the hdmi or displayport. The laptop does not give an error code either. Ive tried several TDP values from 115000 to 200000 but always the same result when i flash a modified vbios. If i then flash the stock bios it works like always.

 

The rom file is 86.04.56.00.3a. Sorry it wont let me post it

 

My programmer is on the way. Still deciding if I want to go ahead with the mod.

i'm not sure if the pascal tweaker removes the header part of the vbios.
the header part of vbios contains some verification stuff that you need to remove for your vbios to work.
basically, delete everything until u see your first 55AA in winhex.

 

I am also using 86.04.56.00.3a for my MSI 1070, it works fine to me. The situation that I experienced black screen on boot was checksum not corrected. But the tool will automatically correct checksum to the original value once it's saved. Did the programmer successfully flash the modded vBIOS into the chip? Or did you go through the procedures of erasing, blank checking, programming, and verifying?

The tool doesn't touch the header part of the vBIOS.
Since the stock MSI vBIOS is working for his Zotac card, I am guessing it's not caused by the header.
Also I checked the stock 86.04.56.00.3a, it started at 55 AA.

 

do you keep the throttling at default?

a screen grab of your bios in the app to show the settings would be good

 

This is my current settings. TDP values referred from MSI 1070 Gaming X ( https://www.techpowerup.com/vgabios/187158/msi-gtx1070-8192-161024).

 

mine shows the checksum in red.

EDIT: So I just flashed the vbios version you listed and it's still working on my card (bar the lack of g-sync). Should I get the extra 330w PSU to power the TDP bump?

 

Mine is in red and does not correct. That would be the only thing i can think of but its also red on stock and flashes and works just fine.

 

I downloaded 86.04.56.00.3A from MSI and it was showing green. I even flashed it and my GPU is still working.

 

That may be my problem ill troubleshoot.

 

P870DM-G and 200W 980 = single 330w. I can't think the 1070 will push more than 980 desktop card.

 

I wanted to try 150w but people are freaking out over it... Me more so.

Looking at MXM spec, the max voltage seems to be 162W at max (6% tolerance)



I cant find the original file, Take a look here:
http://www.docsford.com/document/1486552
and rev 1.1. of this

http://www.docsford.com/document/524241

or search over the net for: MXM Version 3.1 System Design Guide

 

Well after quite a bit of testing it seems that the laptop will not start properly if any bit of the original TDP settings are touched. Ive tried both stock and modified as well as stock and then saved using the tool to see if it somehow influences the way the laptop reacts by using the tool. I've narrowed it down to being the specific modifications using the tool and the alienware17r1. for some reason if it differs in anyway from stock it will not boot. It is really weird because it does not give me a failure or power off. It just displays a black screen and fails to boot.

 

just a question, i thought MXM supports at most 200W? (w/o External power cord)
How did you get it to work at 250W?

 

Exactly! There's something missing here.

It's just a power limit. It wouldn't draw that much at POST.

Personally I think he's lucky it didn't work. I would guess if actual draw got up that high for any length of time that it'd be a race between which burned first, the fets on the mobo or GPU

I would advise not to shoot for the moon in the first mod. Try something within tolerance like 130W or 140W and prove the concept by monitoring. Then go from there

(don't forget the gecubes burned themselves up at 150W)

 

It's just a Power limit?

 

It seems that in games like Battlefield 1 the cpu is drawing about half its rated TDP.

As in, its a limiter that *lets* power draw be higher but doesnt *make* power draw higher for the card doing the same work

POST wouldnt draw enough to bring the limit into play, therefore if its not limiting anything its not responsible for the non boot. Is my thought process

 

Its strange that in clevo and msi models the pascal tweaker works but in an alienware it will not post if the bios has been altered. I think its a dell thing
