1070MQ Typical Undervolt?

[ShadowChaser]

My Aero 15x has been running rather hot, so on top of repasting and dusting off the system I decided to undervolt the GPU and reapply the LM on the CPU.

For the GPU it's currently running 1430mhz core @ .700v according to GPU-Z and 4704mhz mem which is +700. All clocks were applied in MSI Afterburner and verified with GPU-Z

That's about as far as I can push it without going unstable in certain games. Is that any good?

Temps under load are quite reasonable. In Heaven I'm getting 60C on the GPU and hottest core was 65C on the CPU.

I'm more worried about temps than anything, but wanted to know if the 1070 was doing well

1070MQ hitting power limit already?

Nope, currently when undervolted it's not hitting a power limit except for stress tests like furmark, in which case it'll throttle to ~1200mhz

In games and heaven/valley it's not hitting a power limit or voltage limit

 

Edit: I see you also are a tweaker  I'm trying to undervolt my 8750H but can't seem to get any good (ie. visible) results

I myself would allow the GPU to draw more voltage and run higher clocks since the temperature looks good

because CPU's power management see the power draw drop as a sign to ramp up the frequency. Run benchmark, say Cinebench and you'll see performance increase.

These clocks are for maximum mobile performance anyway ^^ I'm still trying to get the gpu under 50W load

And I'm also trying to lower the temps on CPU, because even with LM once both chips are going the CPU gets a little toasty. I'm not trying to get performance gains I'm trying to get efficiency gains. I really want to stretch the battery life as far as possible.

drag PL1 and PL2 down then. Depending on software it can also be called Turbo boost power limit and Turbo boost short power limit. Something like that.

okay, will try that, but now, under a combined aida64 FPU + Heaven benchmark temps are looking more reasonable

CPU is 81C @ 3.15 Ghz so it is still throttling somewhat at 51W power draw but still boosting

GPU is 70C at above clocks (~98% util) and ~68W which I can live with.

Under load it still takes more than 120W which would be the sweet spot for me.

you could lock that down to whatever number you want with PL1. I tend to keep PL2 the same as PL1 to stop it from boosting super high for seconds and make the fans go nuts.

heh the fan control on the aero 15 is slow enough that it doesn't really do that
I do want to preserve some performance so I think 50W is pretty good  got CPU and iGPU to -100mv and it's stable. Will push further once I drop the PLs
