Retirado do NBR, rapariga com o mesmo problema do bd prochot:
@ryzeki and @Falkentyne, I can also overclock my CPU and torture test it in prime95 (worst case scenario) when overclocked to 4GHz or more without any throttling just overclocking using XTU or even basic dragon center settings (my gt72vr came with 6820HK) but problems only happen when GPU is also stressed at the same time (then even stock cpu clock does not save me, tried uninstalling XTU, dragon center etc just in case, increased the voltage/power to cpu, decreased it, nothing helped and most things just made it worse). The only time this happens is in games like AC origins or when running cpu and gpu bench at the same time. Idk why and I hope MSI will figure it out as my laptop has been missing for a few weeks now. I will call them up Monday or Tuesday to find out where it got stuck or if they have some news. I really miss my laptop already as using my bf's old pc is less than ideal. Cannot even run old world of warcraft smooth let alone any other game. So I watch a lot of series now and study some more haha. The poor 10 year old setup with 6 core AMD 3GHz processor and 1GB gpu handles that much.
Haven't seen such behavior. Mine runs full speed with both CPU and GPU stressed.
Was able to pull 355W from the wall with a 1070 (TDP modded) system. (System was probably using 320-325W total draw + PSU inefficiency)
Prime 95 AVX blend + 195W TDP GTX 1070 running Valley at the same time. (Had to disable hybrid power the annoying way, by unplugging the battery, setting EC RAM register 31 to "09" and EC RAM register 42 to "64", otherwise CPU would throttle to 45W at 160W system power draw, instead of drawing 100W by itself.
I only saw this "BD Prochot" behavior on BATTERY power, not AC. CPU would drop to 800 mhz if too much load was on the battery from video card load. On battery power, CPU is forcibly limited to 45W at all times if there is no load on the GPU. Disabling BD prochot would prevent the 800 mhz CPU throttle, but would force an instant windows shutdown if that load continued to be that high (not a complete power cutoff, could actually see windows shutting down quickly, but it was too fast).
The point is, if their units throttle the gpu (and no one noticed before buying such as I have not noticed), it makes sense they don't throttle the cpu as the total power/voltage draw would already be low enough. Hence why bd prochot would never be an issue. The question is which one is the normal behavior - or are they both abnormal...? The MSI guy I spoke to on the phone told me my laptop did not behave normally before I sent it off. So maybe it would have been normal for the gpu speed to lower instead? I mean it makes no sense that the gpu reaches higher speeds in games like AC origins but not in other gpu demanding games/benchmarks that do not stress the cpu as much. It all just seems weird to me. Oh well. We will see when I call, hopefully will have the time tomorrow to do that.
Mmm maybe your laptop does not throttle as severely as mine for some reason but I could totally replicate it running 2 benchmarks (one that only stresses cpu and one that stresses gpu to 100% and cpu minimally). I mean I understand there would be some power/voltage limits but what I don't understand is why it does not stop sending so much power to the cpu/gpu before it reaches the point where it needs to severely throttle like this. I mean ffs it's a laptop made to run as a whole. If I was a stupid person trying to make pc setup that requires 500W supply work with a 300W one no one would question who is in the wrong. But this thing was supposed to be tested to perform as a gaming laptop the way it is without needing to mod stuff. Or am I wrong?
@Falkentyne how do you manage to pull so much power, do you have a custom power supply? Or does your laptop come with a different one than the 230W one?
Well ultimately it has the same effect as AC Origins. It brings both gpu and cpu usage to 100% or close to it. And I suppose they had to figure out that sooner or later there would be games that stress the hell out of these laptops (at which point it would be really bad to throttle like this). So I think yeah, they should be made to run it. I would not mind the gpu to lower the speed and power consumption at that time, not at all. But the fact I have to do that manually using afterburner and lock its voltage is beyond my tolerance for how a laptop should behave on stock settings. Especially since mine comes with an unlocked CPU... I am all up for limits, I know I bought a laptop. But having to download 3rd party programs just to make it work somewhat okay? I might as well demand money back and built a gaming pc and buy a huge suitcase to take it with me on holidays. Just have to work up a lot of extra muscle. A lot.
Now I just noticed. In all those stress tests in notebookcheck reviews, the GPU's downclock severely to like 1200MHz when cpu is also being stress tested at the same time as gpu. I never observed this kind of behavior in my laptop even after factory reset which may suggest there is something going on which results in weird behavior. In my case my card was happily running at full throttle over 1700/1800MHz under stock settings reaching max voltage at times even though cpu was also stressed to max. Maybe some voltage regulator died or something? Motherboard was not correctly sending signals for the gpu to draw less? Now that I think of it, when the cpu was not being stressed the gpu actually ran at lower clocks (around 1600 or even less). Now this does not make any sense to me? Why would the gpu use more power when the cpu is also heavily used rather than the opposite? Mmmm. Can anyone confirm this behavior?
@StreeTunder,
@pedro69?
Also the gt73vr 6re and gt72vr 7re on notebookcheck seems to throttle gpu to 1200-1300MHz when both are stressed. Can anyone check how their laptops behave? Or was it just the review units behaving like this for some reason?
To replicate the issue I just used throttlestop's own cpu bench combined with unigine heaven and it eventually throttled same way as in AC: Origins. Then I decided there must be something wrong, packed it up and dropped it off where I bought it for warranty. I mean on notebookcheck you have all these reviews on these laptops where they stress test them with prime95+GPU bench at the same time and it does not throttle so I guess there must be something just going wrong here as the laptop should handle it.
Why to spend time thinking at all? You are not engineer, let MSI think about it, you payed for them thinking building and providing you a working product, period.
We all like 'upgrading' items with either new hardware or overclocking with software for higher than stock results but fixing? What is below advertised stock? No, we shouldn't.

A pedido do user
@Daniel_1110, no qual eu agradeco a dica, fiz mais um teste ao G-Sync no AC Origins.
Ele pediu para bloquear os fps a 58 e a 118fps, no msi afterburner, a ver se melhorava o piscar / flickering,
a resposta é não, não faz nada.

Não noto diferença nenhuma:
Fullscreen,
58fps = 60fps, igual, não há diferença, notasse bastante
118fps = na casa dos 100fps, igual não há diferença, noto um bocado menos
30fps = é mesmo a melhor opção, é quase inexistente
V-Sync desligado ou ligado, dentro do jogo ou nos Nvidia settings = não faz nada (o v-sync só funciona se os fps estiverem a 120fps ou seja de nada vale ligar isto)
O que é absurdo é que a maioria das pessoas indica que quanto menor for a frame-rate mais se nota o piscar / flickering, ou seja mais na casa dos 40 / 30 fps e para baixo.
Aqui não é o caso, quanto mais perto dos 60fps ainda mais noto o flickering, 70fps / 60fps / 50fps, é quando noto mais, principalmente a 60fps.
Quanto maior for a frame-rate, apartir dos 80fps, noto cada vez menos e melhora bastante, mas mesmo assim noto qualquer coisa.
O que melhora mesmo, ou até elimina de vez é jogando a 30fps lol
O ecrã sõ pisca do lado direito apenas, outra coisa mais absurda e estranha.
P.S
@Shark00n e
@Miguel_Pereira,
Se puderem instalar o AC Origins, metam em 60FPS locked (o jogo tem limitador de FPS), desliguem o V-SYNC dentro do jogo e na Nvidia settings, e vejam se notam no ecrã alguma coisa, olhem para os cantos.
O ideal é estarem cá fora, com sol, dentro do jogo, assim com claridade, e mexam a camera para os lados.
Parem a personagem e olhem para o ceu e parem o rato, não se mexam, parem o rato, olhem para os cantos, (principalmente do lado direito).
Tentem parados e a mexer a ver se notam algo.
Tenham a certeza que estão mesmo a jogar em fullscreen, porque borderless funciona 5 estrelas.
Pago-vos um copo se me derem esse feedback!
