Lenovo Y700-15ACZ GPU downclocks to 300MHZ while gaming from time to time. No overheat or TDP proble

Hi all

 

Please some advise. I have the Y700-15ACZ (FX-8800P, M385X 4GB). While gaming, the GPU clocks go down to 300MHZ from time to time (about every 2-3 seconds). I don't see why - the TDP remains the same according to HWInfo and the temps are quite ok.

I even used MSI Afterburner and downclocked the GPU to 0.5GHZ/1GHZ (core/memory) which is a lot lower and it still happens (and TDP/temps are much lower too).

 

Any clue?

 

I've tried several drivers from Lenovo and from AMD and nothing helps. The performance is actually quite ok, except these jumps in clocks..

Thanks

Hi gaminglaptops , 

 

Greetings. 

 

Would this be happening without a charger connected ? 

Try to set the power option to high performance and connected with the ac adapter . 

Use similar software like GPUz and enable the log to file under sensors tab to use as reference . 

See if running it on high performance with attached adapter . Set the program to run on GPU card .

 

Update us how it goes.

 

Regards

Hi spidey101!

1. Tried both "balanced" and "high performance"
2. logged the results using HWInfo (logs also CPU and other components)
3. Yes, the laptop is connected

4. The problem is not constant throttle - it just goes down every 2-3 seconds, you see? and it shows in the logs. GPU temps remain under 80C

Hi gaminglaptops  , 

 

Aside from updating the BIOS you may also check it with technical support for further recommendations. 

There are claims from some post also , but get a differential output log using GPU-z for comparison.

There was no bios update since it was released

 

And the problem that is described in other posts is talking about the CPU, which I don't have problem with, plus, the recommendation didn't help me

Specially if the issue would interfere on the performance it would be best checker and tested futher. 

Best that you call in technical support for futher evaluation.
