Do the new Clevo Laptops still disable Turbo boost when the dGPU is active?

Hello guys,

The last time I purchased a Clevo laptop was back in 2012, which was the P150EM.

At that time we had to force the CPU to run at Turbo boost clock with the help of ThrottleStop when the dGPU is active.

Is that still the norm for the current Clevo Laptops?

 

I don't remember the EM doing that on mine, but not on the equivalent models just now (P650/P9xx)

 

same here, got a couple of P170EM and P150HMs around, none are not boosting without TS.

also @hackness sweet mother of god, how did you push the RAM that far?

 

That's good.

It was a very old issue.

Hi there @Meaker@Sager, there was a thread in the past where you and me also joined the discussion about this topic:

http://forum.notebookreview.com/threads/clevo-p150em-not-turbo.713088/

It appears some members were not facing this issue, but some were, but the behavior of no ThrottleStop vs have ThrottleStop that I was seeing on my P150EM was that one touches the Turbo boost clock then bounce back down and bounce back up again quickly which results in performance loose, and other case just stays at Turbo boost clock full time with zero drop whenever a game is loaded. I was seeing this issue with TDP limit raised to 65W using XTU, but was eliminated by setting the current clock speed to the highest turbo clock speed in ThrottleStop.

It was with a lot of Trials and Errors, with many CMOS clearings by long pressing the power button Many thanks to @Johnksss for getting me past the 2933 barrier, and also thanks to @Falkentyne for teaching me the rules of RAM OC'ing

 

That was back 5 years ago and by the looks of it was not a design characteristic some of the mainstream 13 inch machines did do that on purpose.

 

I had this concern was because I saw this picture in the notebookcheck's review on the N850EP6:



The temperature is only 70C on the CPU side, power is only 26.56W and yet the clock speed is running at base clock which is 2.2GHz for the 8750H...

What??? Is Clevo doing that again?

Prime/AVX and furmark together is going to produce some funky results.

 

It is a little weird because other manufacturers' products have the throtle kicks in when they reach the TDP limit or BD prochot, but neither of these seem to be the case though. Especially seeing it at 70C and 26.5W. I mean If the TDP cap is set to 35W or 25W, it should be at 34 point sonething or 24 point something, shouldn't it be like that? Yet it choosed to stay at 26.5W?

 

Honestly I wouldn't bother with Clevo atm. Their thin and light are pretty bad compared to others such as Asus and Gigabyte.

 

Gigabytes machines have been overheating listening over at reddit.

 

Yet their Z390 Aorus Master runs nice and cool and fast.
Do they hire Dell's laptop team to design their laptops or something?

 

I was picking between the MSI GS65 and the Gigabytes's Aero 15x v8 but I picked the GS65 simply because I don't want people to look at my nose hair through the webcam But I'm kinda glad I made this choice, some 15x v8 users are having their key caps falling off (lol).

 

But why research your recommendations?

 

This thread had strayed off a bit .

I was trying to understand how Clevo Laptop works nowadays, to determine that if the Clevo is still worthy for me to purchase as my next laptop when it has come to a time for me to swap.

But the notebookcheck review for the XMG Ultra 17 seems interesting.

https://www.notebookcheck.net/Schenker-XMG-Ultra-17-Clevo-P775TM1-G-Laptop-Review.288972.0.html

P775TM1-G seems to have the same issue though.

Not able to reach 65W PL1 under CPU + GPU stress test.

Instead it stays at 48W and lower the clock down to 2.7GHz while still only running at 71C Max on the CPU side.

However the dGPU is hitting 90C but running at a pretty high core clock for a stress test.

It is still kind of weird though, when both the CPU and dGPU are stressed, instead of lowering the dGPU clock speed, Clevo chooses to lower the CPU clock speed.

Consider some games rely on the dGPU more than the CPU, this kind of protection is probably a plus.

But it is probably is a little too overly protected on th CPU side though.

Consider that 2.7GHz is not even reaching the base clock which is 3.2GHz while not reaching the 65W TDP cap, and most importantly the CPU temperature is only 71C.

But still, there isn't enough information to make a complete judgement, it is possible that the power brick has reach its maximum wattage, consider that the GTX1080 is running at a pretty high clock while running Furmark + Prime95.

The bios for Ultra 17 itself found on the mysn driver download site shows there is no value in the Tcc Activation Offset under both Failsafe and Optimal mode.

I think EC's probably handling this.

Now I'm not sure if I'll still consider purchasing Clevo as the next replacement laptop though.

There is still quite a bit of time before I needed to get a replacement anyways.

 

Not sure what's going on with NBC's review units, but IME there is no throttling of the CPU under combined load even on stock BIOS with the CPU and GPU both overclocked (P775TM1 and P75xTM1 are the same motherboard).

 

Could be buggy Control Center affecting performance. Or wrong settings in bios. Maybe @XMG know.

 

My guess is probably the Control Center. I have never had that crap installed and use the high performance power plan in Windows. The default BIOS settings (95W PL1/118.75W PL2/28s Tau/108A TDC current limit and unlimited ICCmax) doesn't throttle like NBC shows.

 

Yes, Hopefully it's because of the wrong settings.

The NP850EP6 also shows the same sign when it is reviewed by the NBC. It was also sent by XMG though

If that's the case, NBC may have been using the wrong settings to review the Clevo laptops

 

This is a BGA Jokebook. Can't expect much more.


BTW... From the link. Update 06/23/18: after much fiddling around we were able to discover that the Control Center was the culprit behind our GPU throttling issues. Killing the program via task manager immediately restores regular behavior of our GeForce GTX 1060. In "The Witcher 3", the GPU ran with enabled turbo boost at around 1,645 MHz, as can be seen in the graphs and screenshots. Given that we saw the same behavior on the Key 15 and the XMG A707 (currently in review) this particular bug seems to be affecting all Clevo barebones with preloaded Control Center.

 

Didn't see that, glad that they did find out why

 

@XMG

Does Clevo know this?

That their Control Center is causing the Throttling?
