Oc'ed 880m but monitor shows default clock

[beatc]

Since i got my hands on GTA V, i started to overclock my 880m in order to play the game in full high settings. However, when i checked the monitor(tech gpu and asus gpu tweak), the clock stayed at default one which is 954. Is this normal or is 954 is the max clock i can reach with 880m? Btw, I used both msi afterburner and asus gpu tweak but still the clock remained default.

beatc, the clocks change based on demand, and will downclock after the load is gone. Depending on how you have your 3D settings set in the Nvidia Global / App settings, you can keep the settings high after game exit a bit longer with the "Power Management Mode" set to "Prefer Maximum Performance" rather than "Adaptive" (default) which downclocks like Balanced performance setting for CPU:



Don't forget to set it to use the Advanced 3D settings as well, otherwise the application settings take effect as default:



GPU-Z will show you default and max settings as well as active values in Sensors tab:

Default and OC clocks highlighted


Idle values showing in Sensors


Full speed OC values showing under load generated by GPU-Z built in load test


Make sure to disable the OC setting in GPU Tweak so it doesn't override the MSI settings. GPU Tweak for JZ 880m is max OC of 5%, that will kill the additional OC from MSI Afterburner 🙂

Have fun 🙂

First of all, thank you hmscott for giving a detailed explanation. I read through it and followed your instructions but still the gpu core clock in the sensor tab displayed default clock value during the render test. But then, i realized that the Gpu Tweak for Laptop application is still running because of the loud fan noises(before this,i set the gpu fan to run on full speed). So, based on what you mentioned before, I turned off the gpu overclock option in the gpu tweak laptop and ran the render test again. The sensor finally showed the correct clock value.

880m is not OCable, if you read this 19 page thread where professional overclockers speak on the matter youll get what i mean.

as for some users here im pretty sure they are on nvidias payroll so keep your eyes wide and ears shut 🙂

broadleaf, you didn't read beatc's post all the way through, he disabled OC in Asus GPU Tweak letting the MSI Afterburner settings take effect, and then he got the full OC with his G750JZ 880m, and verified it with GPU-Z Sensors. 🙂

"I turned off the gpu overclock option in the gpu tweak laptop and ran the render test again. The sensor finally showed the correct clock value."

The problem was found and resolved, no need to jump the shark trying to pull in some perceived conspiracy of Nvidia, when in the case you refer to, it is simple poor design and implementation by Alienware.

That series of posts you linked is from the Alienware 880m GPU design failure; they truly messed up their 880m implementation, any OC causes throttling. And, as it turns out, that design flub continues in some Alienware models with the 980m and 980m SLI.

That failure fest is due to Alienware, not Nvidia.

Asus did a good job allowing the 880m to OC to the maximum allowed in the vBIOS in the G750JZ without throttling.

The Asus G750JZ 880m is overclockable, but the Alienware 880m isn't.

"I read 80% of the posts on here and am extremely disappointed with their lack of reply or any realistic fixes to these problems. I wasted so much time and $$$ having Alienware exchange my AW 18 three times thus far due to terrible GPU performance. This is my third brand new AW 18 with 880M SLI, 4910MQ, 16GB RAM... I've had it after trying to play Grand Theft Auto 5 with their latest driver and very poor FPS, what a useless waste of $ this gaming laptop 'project' turned out to be, and this is not Alienware's fault--but NVIDIA.
...
My warranty expires on this gaming laptop in 3 weeks... What should I do?? I am clearly NOT even close to being happy with it's terrible gaming performance! Nowhere near worth the $ I blew on this crap!"

Not Nvidia's fault 🙂

The Alienware problem can't get solved by an Nvidia driver update... very sad really.

That's why we buy Asus instead of Alienware. Because Alienware doesn't work, and Asus does. Also Asus is much more reasonably priced, and Alienware is an unreasonably huge expense for nothing more, and often much less, than Asus ROG laptops.

Here is a list of Alienware threads from notebookreview.com, lots of sad stories, lots of wasted time debugging.

Is it possible to upgrade the Gpu in the G75JT laptops?
