GTR73 GTX1080

has anyone successfully flashed a modded bios that allows to thank the power limit or changed the throttle temperature to something higher?

With a 1080 setup I think it's very dangerous since you're already at 200ishW capacity. Increasing it will likely kill your card, like coolane did. So by all means go for it if you want little more performance but if it breaks, nobody is to blame but yourself.

 

cool cool, i did not know that, what about disabling throttling you think that is safe?

 

Please don't listen to Danishblunt. He has absolutely NO idea what he's talking about, @Papusan is the master, trust him. And Coolane's card was temporarily killed by FLEXING due to having to use an improper heatsink (980) on the 1070 which has a slightly different layout; cause damage to the traces. VRM's didn't blow from the TDP mod, rather flexing and thermal stress from the flexing did. The card was fixed by Khenglish.

The MSI GTX 1070 has been tested by Khenglish to be able to handle 250W of TDP on the card itself, so obviously the 1080 would be able to handle it.
The card isn't the issue. It's the mainboard. The power delivery system would give out before the card itself did.

No one has TDP modded a 1080 on a MSI laptop yet. Only on clevos (a few users here also TDP modded some desktop 1080's). The TDP mod would work but it is unknown how much the laptop's power delivery system would be able to handle over 200W TDP without something failing on the mainboard. I've successfully tested 195W TDP directly through the MXM slot on my GTX 1070 long term without issues; the MXM 3 slot is electrically rated to 195W burst power anyway, and the 1070 does not have an auxiliary power connector either, while the 1080 does.

However to do this, I had to do something about the 230W AC power limit, which is set based on the GTX 1070 being detected at POST (exceeding 230W=CPU gets throttled to 45W then 25W), PLUS NOS battery drain is draining almost 10%/hour if the 230W limit is in use and you are drawing very close to 230W to the entire system (battery drain starts at the GTX 1070 NOS "cutoff" of 160W).

Thankfully this is easily avoided by changing EC RAM register "E3" from a value of 90 (10 for skylake) to 91 (11 for skylake), which changes the power ID from 230W to 330W, and also "removes" NOS battery drain below 230W as well (HOWEVER it does NOT remove the 160W NOS AC cutoff if battery is below 30% or is disconnected, when the GTX 1080 should have a 240W cutoff at POST; it seems this cutoff cannot be changed via EC registers).

I would definitely not go past 195W directly through the slot on a MSI (Clevo DM3 would be able to do 260W according to Khenglish and Coolane's tests)

You're perfectly free to try if you want, but this is unknown territory and I take no responsibility if you destroy your mainboard.
Even it works, you are going to have issues:

1) high battery drain (NOS system) because a 250W TDP GTX 1070 is going to be drawing almost 10%/hour from the battery when you get close to 330W draw to the system.
2) Exceeding 330W to the system: It is UNKNOWN whether the CPU will be power limit throttled by the EC if you exceed 330W of power draw. There is provision for 460W of power but that is only for SLI systems AND if the SLI power brick is installed. Sirgeorge tested disconnecting one of the two power bricks on his GT73VR SLI system and had CPU power throttling when he exceeded 230W by running SLI, which he did not have with both bricks (and that's also ignoring the fact that the 230W delta will shut off past 250W system power draw or 280W draw from the wall). The Delta 330W should be good for at LEAST 380W---I believe a user tested the PSU pulling 380W from the wall. I was only able to pull 355W from the wall as I couldn't get any more power usage with 4.4 ghz AVX small FFT prime95 (100W) + 195W GTX 1070 + keyboard+mouse+system (LCD, Dram etc).

If the CPU did NOT get TDP throttled to 45W on a TDP modded GTX 1080 if you exceeded 330W power usage, you would still have to buy the Eurocomm 780W PSU to avoid overloading the 330W AC adapter. That's IF the mainboard didn't give out and the power delivery system was able to handle a 250W TDP GTX 1080. And if it DID handle it, how are you going to deal with the battery drain from the NOS limit when you reach 330W? That's if the CPU didnt get TDP throttled to 45W if you did?

You're on your own. I mean it's your money.
If you're willing to risk your mainboard, willing to risk dealing with CPU power throttling at 330W system draw, if the mainboard actually accepts 250W to the GTX 1080 without something blowing, and have an Eurocom PSU available if somehow you do NOT get CPU power throttling AND the system is somehow able to allow the 1080 to pull 250W, well...all I can say is "Good luck."

Either way, making this work would cost you a nice chunk of change (mainly for the 780W PSU, because if it DID actually work, the 330W PSU would no longer be enough).

 

I think that should be fine, the 59c throttling of the card is stupid. You could probably set it to 85c or soemthing.

 

So, as far as i see, you changed your EC to a gt73 witha gtx 1080(obv with a 1070) so that you could get more power draw for your card.
Now, if by some means, ou could ask someone with those gt73 who had 1070 sli, you could make your EC settings of that model, so that you can draw 460w of total power?

Does your titan have a second mxm slot?( i heard the gt73 with cm238 have a second mxm slot).


Maybe, im wrong, @Papusan could you guide me here?

 

What are you talking about.

He has a GTX 1080, he didn't change anything.

He just wants his card to run stable, but thanks to the 59c throttle in the vBIOS it doesn't run stable.

 

He has a gtx 1070( am talking about @Falkentyne ). He said that he cant draw more power then 330w, and hence his cpu throttles to 45-25w

So, i suggested a way that maybe, could grant him more power.

 

Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.
Can't see his posts that's where the confusion is coming from, sorry by bad.
