question about clevo p177sm-a and gpu throttling, what is gpu throttling

Hello guys

I'm really interested in buying this notebook, clevo p177sm-a, but reading some reviews, there is a complain about gpu throttling. What is this exactly and when it happens ?

the review i'm talking about:

Review Clevo P177SM-A (Schenker XMG P704) Barebones Notebook - NotebookCheck.net Reviews

"There is much less complaint about the temperatures. Clevo has adjusted the fan so that the graphics card and processor do not exceed 90 °C (194 °F). It is just too bad that the GTX 880M tends to throttle to 810 MHz in extreme situations. The Core i7-4910MQ did not struggle with throttling in the stress test. "

and again:

"We see drawbacks primarily in the weight and noise production. It is also upsetting that the GTX 880M lowers its clock during full load (should not happen in gaming routine). Apart from that, the XMG P704 is a very good and individually configurable gaming laptop."

should i get worried about this ?

and i'm planning to overclock the gpu, the best choice is the 17 inch version ?

thank you guys and sorry my poor english

 

Throttling is a built-in safe guard that causes the chip to downclock when a designated temperature is reached. The chip lowers its clock speed - or throttles - at said temperature so that the temperature will drop, thus avoiding the computer from shutting down and avoiding thermal damage.

As mentioned in their review, this only happens in extreme cases. Good "cooling practices" avoid overheating and throttling.

 

Thank you

But it's possible to know the max temp until the gpu underclock ? 90º maybe ? as said in "Clevo has adjusted the fan so that the graphics card and processor do not exceed 90 °C"

So is not very easy to overlock in this notebook, right ?

 

92c is the throttle point for the gpu.

Remember there is a difference between throttling and not turboing at maximum possible speed.

 

So this is not a big problem ? I read that the cooling system of this notebook is good, but i'm not sure if i will mantain under 90ºC all the time with moderate overclock.

The cooling system of the p177sm-a compares to the 17" asus notebooks ?

 

I have the P170SM-A and highest I've seen the GPU get to was 82C after several hours of playing watchdogs on ultra.

 

how about the air temperature of your city ? use some kind of cooler pad ?

 

No cooling pad, and I live in Houston so temps are 90F/33C+ fairly often during summer. I only use laptop indoors though, current air temp is 73F/23C.

 

Under normal use or normal gaming the cooling system is good enough to keep it from throttling. It usually happens when you run programs that are made to really stress the components like Prime95.

 

If you want to overclock you should be doing all the things that help temperatures with it.

 

Just to confirm, as it was one of our XMG P704 models in the OP review link, it's not an issue under normal operating conditions as has been noted by other members. Notebookcheck are very very thorough in their reviews and tend to stress laptops to their maximum possible load, whereas most magasines will test "real world conditions". The key phrase in the review is "in extreme situations"!
