Gl551JW: Power Limit Throttling and random BSOD problems.

sureley...i think

No... power Limit Throttling happens only when your CPU reach the TDP.

You have a 4720HQ? In that case, your TDP is 47W for long duration and 58W for short duration (8 sec by default if I'm not wrong).

In which scenario are you experiencing Power Limit throttling?
In some stress tests/benchmark it's normal, and CPU throttles itself to not exceed 58W for the first seconds and 47W for the rest of the stress test/benchmark.

I experience it during long stress period in XTU. I also get 1-5% current limit throttle. I did not get these power throttling before. It does not throttle during first couple of seconds then it starts to do it throughout.

It's normal with stok values.
When you see the Power Throttling, how much is the Package TDP? If it's 47W, it' ok.

You can raise the TDP limits to 50W/60W in XTU, current limit to 90, and undervolt your CPU.
Less volts = less watts for given speed (given multiplier) = less throttling.

However in gaming you will not reach 50W normally, because they don't use all 8 thread at the same time.

The package TDP is at 46-48 while throttling. http://imgur.com/enrMuFR

Btw, how do you increase those limits?

[andreacos92]

You can use XTU, and set them to 50W/60W. A little improvement.

Or use ThrottleStop, you have no limits, but you have to be careful because higher TDP = higher temps.
However, check if you hit power limits during your games or your common applications.
If not, no need to increase Power limits just for stress tests..

I found it but its still 100% power limit throttling?

[andreacos92]

As I said, its normal.

I reached 85+ W with my 4710 with stress tests that use AVX2 instructions.
But after 2 minutes you reach really high temperatures and CPU starts to thermal throttling. So it's a no sense.

I sugges yout to not go above 70W.

have unlocked 55 long and 60 short but when load is 100 on 4 cores i only use 51-52 w in throotlestop
