I'm sorry but the patient is dead.

Ah thermal shocks could have been the cause.

 

Due to the insane TDP levels?

Partially.
If there are too many too hot / too cold areas on the board, that rapidly heat up and cool down too many times, that can cause the board to stress up.
This might be because of the super high TDP, or might be because the heatsink cant cool that much TDP fast enough. Difficult to tell.

 

They did say that the heatsink wasn't contacting them board correctly. I did the same mod and it's working fine for me so far. But I am also not pushing insane TDP levels as well.

That could be the case. The front of the card was well covered and cool, but the back of the card had nothing attached(I used to have a large thermal pad put underneath, but I dumped it away and used fan to blow the side). Maybe the thermal difference between the front and the back caused accumulative thermal stress/tense created micro-fratures, adding the fact that my board was bent and I heavily loaded it with Furmark/FS Ultra.

 

Good chance yeah. I have seen this happen during BGA rework, without the proper equipment. Specially when people try to work on larger chips and heat up that larger area take the chip off and cool it too fast. Instant bending or broken solder joints.

 

So that means a new 1070 is needed?

Ha, you really didn't like that GPU did you, you gave it one hell of a flogging - I'm gonna call the RSPCG!

 

Not sure yet, Khenglish hasn't confirmed if the card can be fixed. I don't feel like of getting the same card while I can smell Volta is not far away, wish the MSI 1080 could worked on the DM1 then I could called it an upgrade.

Ha, pushing it to the limit as always!
Actually the MSI 1070 is quite robust, more robust than the 970m and 980m that I played with. Probably it died just because the way that I treated it, .

 

I can't smell Volta any time soon. This is what happens when you have no competition. AMD dropped the pooch HARD on Vega RX, so now Nvidia can just farm the milk cows hard with Max Q and just drag their feet and set their prices anywhere they want.

Look what happened with Intel. AMD actually dropped a tactical nuke on the Intel factories with Ryzen, and Intel was busy pooping on the toilets during the nuclear explosion, and had to scramble hard to release something to counter, so we got Skylake-X and X299 rushed hard. And a $499 8 core CPU.

But with no counter from AMD on the videocard front, Nvidia can make customers sheep bend over all they want, because we have no choice....

 

Ah thanks for reminding me. Yes the high side FET will have +5V on top of the main 19V supply. I only checked that the main 19V was not shorted and assumed the core voltage supply was fine. A blown gate driver or VRM could cause a 5V short.

 

Man, you're like the Dr. Gregory House of GPU medicine.

 

Not only GPU. CPU wise, Khenglish's writings were also helpfull. Famous hardware enthusiasts are passing by this thread

 

Okay so after reading all this, i have gotten links of all that i need, and i plan to do this mod to an alienware 17 r4 with the gtx 1070 and an i7 7700HQ..So my first question is, will this work with this laptop, and how do i use nvflash to find the chip id of the 1070 to know if it will work with that skypro flasher.

 

It will autodetect the chip ID, so you don't need to use NVflash. Besides, autodetection working means that you hooked up the clip correctly to pin 1 and got a full register, and getting an error means you didn't get a connection on the chip pin legs or it's misaligned. So you wouldn't want to manually set the chip ID anyway.

 

I haven't seen case in aw 17 r4 yet, but @EepoSaurus got his 1070 working with the aw 17 r1. I am assuming it will also work on your laptop with careful operations.
You can issue command line "nvflash -b" through Windows's Command Prompt to find out the chip-set model of your 1070.

 

Does anyone know if the TL866CS can be used or do i need the TL866CS? I found a CS for 15$ cheaper so i was going to get that one.but it seems they are somewhat different...just confirming before i grab one of the 2

 

I recommend the Skypro other than the TL866CS:

So i will be performing this mod tomorrow, and out of question, does the preset value let the 1070 range from 150w to 170 if it needs it? or is it just 150w

 

Preset lets you go from like some absurdly low value in MSI afterburner to 170W, even though you enter 151-170W (Adjustable) <--this is what you care about, but it starts at 100% by default.
The MSI slider lets you go down to negative (yes, that's a negative) -99% however, instead of 100%-112%. Don't worry about it.

 

oh so i can will be able to still go to 170w if it is 112%? Or..the card has the ability to use that much

 

The preset values give default 150W to 1070, and it's adjustable through Afterburner or nvidiaInspector up to 170W(112~113%) if you need higher.

 

Ah okay i understand! so with me having the 17 r4...do you think i can handle 175-180w perhaps? my gpu as of now with stock fan speeds, will hit 66-68c. ALso with the 7700Hq i dont thin it will hit my max power draw of 240w

 

The card should have no problem of handling 170W if you can keep it cool(<80C). But your 240W adapter can easily reach its limit, and you might need a bigger one.
The problem that you might run into is the EC might throttle your CPU to a lower frequency during games or CPUGPU combined tests because your GPU is drawing more power.
Since your GPU is soldered on board and you have 240W adapter, I will recommend just stay at 150W.

 

Yes I'm dealing with that problem, even though I have a 330W PSU, system sees 1070 instead of 1080 and caps absolute draw at 230W anyway.

 

So i came across this thread http://forum.notebookreview.com/thr...gtx1080-in-game-random-stutter-freeze.804499/ and it seems it happened after the 1080 was applied with that power limit increased vbios from dell cause of heat...i mean im not seeing any stuttering atm..but is there a risk this can apply to me, after i unlock the 1070 tdp? I have the 17 r4 with the 1070

 

That's a 1080, not a 1070.

 

There is. If the components on the graphics card are not cool properly due to increased TDP, it will age the card and even slowly kill it. Or if your motherboard cannot handle such an increased total system output, it can also degrade and kill the motherboard. Please keep in mind that your GPU is soldered; if it breaks, it will require a change of motherboard(expensive) and have no warranty.

 

I dont have any such thing happening on my AW17. Config in the sig..

Then again im not using the standard thermal pad/paste job.

 

If you are forcing the temperature limit to throttle hard it could cause erratic clock behaviour.

 

You can use schematic from Clevo P670RS as reference ( https://repo.palkeo.com/clevo-mirror/P6xxRS/P67xRS_ESM.zip), this will be close enough for searching for short circuit.
BTW - I have my own method to detect short circuit point: I connect current limited power supply to circuit and checking, what element gets hot.

 

Hello this maybe slightly of topic but just want to ask can the volt mod tools(TL866CS/Skyproll) be used to remove the EC throttling of the CPU?

 

The tools are just for flashing data onto a chip.

The data you want to flash - a modified EC - is your problem.

 

Oh right I understand are there anyways to get a modified EC or to modify an EC?

 

Thanks! I am going to see if this can help finding out what caused the 5v rail shorted, .

 

There are only two modders that are still working on notebook EC that I known: Prema(Clevo) and Svet(MSI). You can see if they can help you.
Modding EC can be difficult and very dangerous, it can brick the laptop easily and hard to recover the default EC back because of the special pins connection.
@Falkentyne has been fighting his EC problem for awhile, he can tell you more about it, .

 

Did you unlock your 1080 to 230W(from your sig) already?
Any benches scores that I can admire, ?

 

Oh alright then I will give him a shout thanks a lot for the advice appreciate

 

That schematic unfortunately does not have any info on voltage conversion and the 5V rail.

You gave me an idea though. AA batteries top out at just a few amps. I can hook one up to the 5V rail and do your what gets hot check.

 

I wonder if an IR cam could reveal the shorted parts.

 

Look at U65 IC and PEX_VDD rail.

 

I'm currently waiting for the 1.8V adapter to arrive and are about to try this myself.
I have a clip (8 pin), the SkyPRO and some cables.

I plan to mod my gtx1070 in my MSI GT73VR Titan.
Does anybody happen to know when the EC will throttle ? Will I be able to reach 125 or even 150 Watt TDP ?

Furthermore I was actually hoping to be able to mod the voltages (undervolt) as I would like to find out if there is a custom sweetspot I could use for maximum but yet "silent" performance.
Are there any news on unlocking or modding voltage ?

Any other hints in general or for my laptop model ?
The VBIOS seem to be on the lower side of the MXM card if I understood what I read so far.

 

Card voltage can be altered through the TB3.0 curve in Afterburner. As I understand, you can't do a true undervolt without locking the clock/volt to a fixed value (no TB3.0). Using the curve, shifting the clocks up higher at each point, and shifting the clock points 'left' down the voltage curve so each clock is hit at a lower voltage point, seem to me to be the same thing...

Ask @Falkentyne about the EC throttle on 1070 - IIRC he has been trying to deal with it in his GT73VR/1070

Re MSI 1070 MXM vbios chip:
http://forum.notebookreview.com/thr...d-feedback-thread.806161/page-4#post-10551239

 

TDP of the 1070 itself isn't that important. It's the total system power, unfortunately. You can draw 170W from the videocard itself without a problem.

You start running into problems when CPU+GPU are drawing more than 200-205W.
I can't do anything about it. i don't have the skills or ability. No one besides Prema knows how to mod the EC, Svet won't do it because it's a guaranteed brick if the hardware isn't there directly, and MSI won't release it, and if messing with stuff in RW everything is possible, no one has said anything. I'm not a coder. I just play videogames ;(

If someone knew how to access the PECI power limits (PECI is controlled by the EC), then perhaps this problem could be worked around.

If you're pulling 150W from the videocard, you should be fine as long as you aren't running any games that use 8 threads. However I dont know about some of those new games that use 4 threads and hammer the CPU. You'll have to test for yourself.

 

In a power limited situation like above you are best off undervolting the CPU as far as possible and leaving it at stock clocks.

 

You don't buy a 7820HK to run it at stock. You can save a ton of money using a castrated 7700HQ if you wanted to do that
I'll just await developments on the EC front.

 

You can do undervoltaging by adjusting the voltage curve in MSI Afterburner like this:

Thank you very much to everyone for all your replies.

CPU Undervolt:
The problem with undervolting the CPU is that my laptop (GT73) might not boot if I need to start it without power source. But I have to admit that I only used Intels XTU. It seems like the undervolting offset is applied no matter if I boot with or without power source - but it seems like the voltage is already lower when booting without power source ... That plus my offset -> blue screen. But probably it's possible to get this fixed with SVETs Tools by setting the values directly in a modded bios... (I got the GT73 as a deal because MSI messed up with the adverticed upgradeability of my GT72's GPU so I have no issue with less CPU power - I paid a lot less for it ... )

GPU Undervolt:
I'm aware that I'm able to lock or change the boost steps... My custom curve actually is a straight line left to right at about 1500Mhz... So my machine is locked at 0.800mV.
But I'm looking for a way to get even lower with the voltage (and I'm willing to sacrifice clock for it) - reason is: I need to find a sweet spot noise/performance wise... I need to up the WAF (woman acceptance factor - as in "Darling ? Does it need to blow that loud ?"). So I hoped that there would be a way to undervolt the GPU with an offset or something alike for situations when I need to run in an optimized stealth mode B-)

EC Power Limit:
That EC throtteling is driving me crazy since I own MSI latops / whitebooks. Had the very same issues with the GTX980M ... So much potential but no way to get there...
Just an idea: It SEEMS like the MSI GT73 is not able to detect which power source it is connected to. It SEEMS to assume that if it has a GTX1080 it also has the bigger power source. There might be a way to trick it to believe it has a GTX1080 also it has not ?
Furthermore and that is something I wished the online press and/or more users would start to complain about: What is a 230Watt (OUTPUT !!!) specced power adapter good for if the Laptop protects it by limiting itself to 200 Watt ?!!? I'm not even sure if the limit is not even lower ! As far as I remember I could not make the GT73 draw more than 200 Watt out of the SOCKET (that's the power adapters INPUT ... So output would be about 180 Watt and that's 50 Watt below the specc )...

Anyhow... Still waiting for the 1.8V adapter... Should arrive this week end...

 

If your workloads are sometimes more CPU bound then it can make sense.
