Clevo N875EP6 GPU power throttling(GTX 1060 6gb)

Last month i bought a Clevo N875EP6(reseller Monster Tulpar T7v16 in Turkey). The first thing i realized that the cpu- i7 8750H- was thermal throttling. Knowing that this is a common issue, i fixed this by undervolting -170 mV with Throttlestop. Now i can get stable 3.9 GHZ on all cores under 100% load.

Recently i realized that gpu usage suddenly drops to around %70 in games that use %99 of the gpu like Far Cry 5 which causes sudden fps drops. I checked with gpu-z and saw that the gpu is constantly heavily power throttling. Thermal's are within early 70 celcius after hours of gaming and it never exceeds 74 celcius which is probably a result of a manufacturer's power limit.The Monster customer service is useless and is not much of help as they are ignorant as hell. I'm thinking this is a bios-limited issue and i'm hoping to find a newer bios firmware but i barely find anything about N875EP6.

Can anyone help me?

 

Sounds like you are hitting a power limit.

 

Which BIOS ver are you currently using? Power limits may still be enforced in later revisions.

Also, Clevo BIOS updates should come from your seller, if you can request them.

 

BIOS version::1.07.09TFB1
KBC/EC Firmware revision:1.07.05

 

I think 1.07.11 is current. It looks like they might have a customization on it, best to check in with them.

 

I will try to provide the new bios from my reseller tomorrow. In case they don't have it, where can i find that bios and would it brick my laptop had i flashed the N875EP6 version?
And is there a way to find out what changes are made in this new bios?

 

It's not usually published openly, mostly only the sellers have it and it's up to them to supply it upon request or not.

Change logs are usually internal, but you can also ask about that if the seller is willing to provide it.

 

They sent me the new bios but they are not willing to share the change logs. Is there any way to get them?

I want to see the logs before i flash it as i suspect there could be lower power limits because of the high cpu temperatures.

 

Unlikely, the CPU follows Intel's spec directly.

 

Maybe an online mirror, if you can find one. Otherwise, unless someone around the forums has it? Might be difficult to come by.

 

I flashed the latest bios and throttling is nearly gone. Still occurs time to time but it is a lot better now. I can share the bios if anyone needs it.

 

Excellent, enjoy

 

Here's another thing i realized:

If i keep the clevo control center 2.0 and its services (especially xtu service) open, gpu power limit throttles and lowers the gpu usage to a lower percent and causes stutters.

If i end the CCC and xtu service in the task manager, gpu power limit throttle still occurs but gpu usage doesn't drop. Even when it drops it only drops to 95% which can be considered normal rather than below 80% .

 

Sorry you're out of luck. All pascal cards except for very few exceptions such as the GTX 1080 in MSI are power limit throttled. Since you have a coffelake system you're basicially stuck to that performance.

 

Gpu throttles at 80 W. Temperatures are around 70. There is definitely more room for performance. I think this laptop can handle more heat. I'd rather be playing at 80 Centigrades than at 70 centigrades with crippled performance.

 

The VRM system has to be looked at when power unlocking to see what room there is.

 

Is it even possible without a bios programmer(even with) ? Can vendors change this 80W limit?

 

Yes, from a board design perspective certainly. The VRM is designed by Clevo.

 

No, sadly once you got an 8th gen CPU there is nothing you can do, even with a HW programmer. Not sure about the details why that is tho.

 

hey guys I have similar problem. the laptop I'm using is clevo p957hp6 (i7-7820hk gtx 1060). couple weeks ago when I received laptop I could overclock and gpu held it's boost without downclocking even if it was hitting power limit, at that time I was getting 14200 graphics score in firestrike test, now I can't get higher 12900, no idea what happened but now my gpu can't even hold it's turbo clock, it downclocks from 1600 when I used to maintain 1850 no problem in benchmark. Temperatures are not the problem, after hour of furmark I'm hitting ~72 C degree temperature but gpu starts furmark instantly with only 1400 mhz core clock, I've repasted but it has no effect. Temperatures in firestrike is 61 max, in unigine heaven 64 C , I can maintain higher core clock but only by downclocking gpu memory and it still performs worse and doesn't maintain full speed. Previously gpu maintained ~1800 core clock with memory overclock when hitting power limit, but now it even can't hold 1600 under full usage.
I don't think temps are to blame, any ideas?

 

I completely eliminated the problem. It was the page file that caused massive stutter and gpu usage drops coupled with power limit. Now that i turned off page file on Windows 10 there is no stutter and nearly no gpu usage drops.
I don't know how page file relates to the power limit and gpu usage but gpu usage doesn't drop now despite hitting power limit and games are smoother than ever.

 

It mostly doesn't, but if you're playing anything that reads and writes from/to the disk a lot, that can bottleneck performance (I don't know any titles that do this, though).

 

Titles like GTA V where it streams content can be impacted.
