** 1070 laptop: "bd prochot" causing cpu throttling to 800MHz and stuttering **

Because of that im now very sad about this situation...like you said is unacceptable.

 

Keep us posted on how it goes, I hope MSI in Portugal will have your back even if the service center does not. That was the case for me, service center was trying to cover the defect and MSI Netherlands helped a lot. Idk if the service center is actually MSI employees or a hired external company but I am utterly disappointed with them, which is why I refused to send the gt75 for fan replacement there. I don't want them touching it at all unless necessary.

 

Send it back for RMA, explain that the situation keeps un-resolved.

Dont wait too long to re-send it to RMA.

 

UPS will collect today the laptop anyways, like i said, Poland center sent the laptop without communicating what had been done on the device.

 

If they communicated it would have been like.... "Soooo we have no damn idea what is causing this, mmmm... Lets install our 100% fixing VBIOS that is a magic tool to fix all MSI laptop issues AND make sure the card is not capable of going over nvidia basic boost spec! GPU boost 3.0...? Irrelevant, the card is like power limited anyway most of the time so no one will notice there is a huge voltage limit now too.... shhh don't tell anyone and pls don't notice so we don't have to give money back to people for our broken hardware...."

 

This was the report from the center...

 

Well that does not say it was exchanged at all so they did not lie "Repair" can mean many things and I am afraid here they meant "hiding the problem which is not the gpu at all".

 

Oh hahahahaha now I noticed it... Oryginal (MSI) Windows License Sticker... That truly is "oryginal" LOL.

 

After i recieve the laptop, Msi from my country asked to the center to see what was done in the machine, they told them that was changed the gpu.

 

Repair VGA card might be something like patching a HW bug on the graphics card through soldering of revised components, it can be add/change/remove.

 

“HW bug” what is that Kevin?

Edit: Hardware bug

Hello @ streetunder ,Have you found the permanent solution? I have the same laptop and going through the same issue.

 

I can give some info about what hapenned in a case of 3 guys from Portugal...and im one of them.

I was the first that discovered this issue here in foruns of NBR, @heliada was the first posting in msi foruns website, streetunder was the first guy discovering the issue with bad gpus.

@streetunder was able to recieve a refund and buyed a desktop machine after many RMAs, he not had only the problem with BD-Prochot...he also got the issue with bad GPU that causes some bsods and could be fixed with a VBios that limits the clock of GPU.

I also had the problem of BD-Prochot and after some RMAs i was able to get a refund to buy a new GT75-8RG and till now not get any issue with this problem, the laptop is amazing.

@JNogueira had the same situation and MSI gave him a new GT63 and also not have the issue anymore.

@heliada was able to get also get a new GT75 proposed by MSI as change.

Pedro69/JNogueira/streetunder, we are all from Portugal and we got the problem fixed buy switching the machines. I was able to fix the problem removing the BD-Prochot feature in Bios and using undervolt in cpu, but we want a laptop that not need removing features like BD-Prochot.

 

Just to add more info, I have a friend that has a GT62VR 7RE with exactly the same problem that is going through the process.

He received the machine on the past Tuesday where VGA was replaced, one of the fans was also replaced (faulty) and they flashed a "firmware" that they don't explain what it is and what fixes (like happened to me).
The problem is still present (BD prochot).

Monday he will be sending again the machine and this time it will most likely be replaced by the GT63 (still to know if by a titan 8RF or 8RG).

Don't wait and contact your msi local support.

Good luck.
Cheers

 

I just feel like msi would be better off actually fixing the issue. Replacements and refunds probably cost more than paying a technician to snoop all over one of these defective machines. I mean, this must be fixable even if it meant to have to resolder some components on the motherboard - which most likely cost just a few cents.
But to say the truth, my old gt72vr had a few more minor issues as well: it had a pretty bad coil whine, the subwoofer cover popped off, it blue screened with newer versions of dragon center and when undervolting the gpu (which is how they stopped bd prochot), you could clearly feel the game wasn't smooth anymore. So yeah, there was no way to make it run well from my side. It's weird though as I run my gt75 1080 gpu undervolted and there is no issue with it, everything is still nice and smooth.

 

It is the same with my GT63.
Didn't try GPU UV yet.

How did you do the GPU UV and how much did you manage to decrease?

Cheers

 

Well undervolting a gpu means essentially locking it to a certain voltage and not allowing it to draw more. Can be done easily in msi afterburner using the curve. Just press ctrl+f when afterburner is open. Then I recommend overclocking by +150 or so and making the curve flat beyond 0.9V - that will prevent it from reaching higher voltage. But I noticed that even when you set it to apply at startup, the curve doesn't apply correctly so you might have to open it every time after a startup and press apply (just create a profile with your fav settings)

 

Perhaps a problem with your version, my MSI AFterBurner works great with the option "Apply overclocking at system startup"

 

It totally applies it somewhat. But sometimes instead of 0.9V lock it might reach 0.95V or even 1V briefly at some points if I don't click apply again. If I click apply once again after startup it doesn't happen.

 

Im using this,

 

My stuttering was related to CPUZ, I had XTU running at the time.
I exited to the desktop, closed all apps that were running on the taskbar, CPUZ was the culprit for me.
Was it the CPUZ or the 'bd prochot'?

 

I never had cpu z on my laptop. And it did the same with every monitoring program removed including xtu and dragon center.

 

I just updated to NVIDIA 398.92 ... and as I'm writing this, an up to 399.07 is waiting.
I also have to update my BIOS to E17A31MS.10A

3 Week old notebook, hopefully the core ups and stability comes soon, I'm getting tired of this......................................

 

If you still can, return your laptop and ask for money refund. This will not solve your problems...

Don't waste your time.

 

Do you have the gt75? If so then nvidia drivers are to blame for lags. The gt75 does not suffer from bd prochot at all. Set prefer max performance under 3d settings for individual games in nvidia control panel OR downgrade to 391.xx or 390.x drivers.

 

I up'd to v399.07, but haven't experienced the throttling since I quit running HWMonitor during game play.
Now I cant get the notebook to sleep, and I have the correct settings in Power Options>Advance Settings.
Coming onto 4 weeks only and 2 issues to resolve.....Not to shabby indeed.

 

Hello guys, my laptop is GT72VR 7RE (gtx 1070, i7-7700hq)
After disabling bd-prochot and tricked current power consumption (thx @ Falkentyne) i got some stable 3,39 GHz on gaming sessions.
But problem with a random drop to 2,7 GHz still exists.
I listed all answers in this thread and came to the conclusion that's firmware problem, but MSI engineers can't fix it? Correct me if I'm wrong.

 

You understood it right. If you are lucky your laptop will run fine with gpu undervolted and that will solve the drops to 2.7GHz as well. In fact that is the only way the issue can be totally removed. However, I noticed some of my games were not 100% smooth at that point (though my gt75 is an amazing undervolter so there might be some variance). You can undervolt using msi afterburner, but I needed to go all the way to 0.82V on gpu or so to get rid of bd prochot and all its side effects.
If it's in warranty, your best bet is to contact MSI. Maybe they have found a fix by now?

 

Thank for you answer.
Judging by the reviews in this thread, where people gave their laptops under warranty, they waited at least a month. I can't wait so much.
And the most tragic thing that some people gave several times to MSI admitted that the problem was in the firmware and replaced their laptops.

 

Well in my case they wouldn't even tell me what was in fact wrong with the laptop, they just said since it was under a year old and has been in service for a total of 4 months out of that time (on and off not in one go) and was faulty for most of the rest of the time, that I would just get a new one. It also has its issues but tbh, it's the best laptop with uncompromising desktop performance (if you are willing to repaste with liquid metal OR deal with loud fans and I don't... so I undervolted the hell out of it and it's still amazing).

 

On my situation, they replaced on the second time I sent it for repair due to unsolved problems of BD Prochot, but I had to insist that they could not solve the problem. They ended up admitting that and proposed a replacement (MSI GT63 Titan 8RG).

But it will depend on your country consumer law and also if MSI has available units for your country as well. Besides me, all other folks from Portugal had refund. Heliada also got a replacement proposed by MSI.

Cheers

 

Well, after talking with MSI for a whole month, I didn’t get a clear answer on how to fix the problem with BD Prochot without turning it off and how to deal with a drop to 2.7 GHz. Now I am on a business trip, and I can not send a laptop - since it is now my workstation.
I decided to undervolt the GPU. But after installing MSI Afterburner and unlocking the Core Voltage slider, I noticed that Core Voltage is counted in % and not in mV.
How do i properly undervolt my GPU? Thank for answers.

 

Are you not able to add offset to the temperature that BD Prochot kicks in the BIOS? Been using that way on my GS65 though.

 

@hackness, unfortunately the problem is not that simple. GT72VR suffers from random BD Prochot triggering. It has no known configuration pattern to solve it. The offset is set to 0 in BIOS by default.
When the machine is under load (for example, playing or using CPU at 100% with GPU stress test), BD Prochot kicks in even with temperatures as low as 75ºC.

It is a power problem and not an offset problem. When you disable the BD Prochot, the CPU has a drop down to 2.7Ghz.
So the guys having GT72VR 7RE bought under performing machines due to bad system engineering.

Only solution is RMA for machine replacement. For those choosing to keep these defective machines, they need ot feel fine having an extremely over-priced under-performing machine.

GT62VR 7RE is also affected in the very same way.
Wish the best of luck for those who still have these machines, specially because a significant number of these machines will be without warranty really soon and MSI will just wash their hands off the problem for sure.

EDIT:
I really don't know why MSI does not proactively contact these users as they know that the problem exists for more than a year. For the sake of transparency and customer focus they should be doing that. It is really sad to see things like this happening and the brand just ignores the problem. They should at least do something like the car brands: Do a defect communication with recall order.
But no... Let's keep it invisible... I don't understand the strategy here honestly.

 

You need to use the voltage curve in msi afterburner. Press ctrl+f, then (you can OC at this point if you want by dragging the entire curve upwards first while holding down shift key - I recommend +100MHz). OCing is optional but should be applied before you undervolt (as once you drag it holding down shift the curve turns to default). Then you can undervolt - find the point corresponding with between .8 and .9V (depending how far you wanna go), then make the curve totally horizontally flat to the right of it. It's important for it to be totally flat.
