FPS Spikes on Y700-15ISK

Evening.

 

I have purchased the Lenovo Y700-15ISK and having installed CS GO I am experiencing FPS spikes every 5-10 minutes of gameplay.

 

At first I believed it was down to the GPU temperature reaching the throttle limit of 67 degrees but after further tests I have played for 1 hour+ and the temperature has not gone above 60 degrees.

 

These spikes happen as soon as I enter the game even if the laptop has only just been turned on so I don't believe it is temperature related.

 

I have the max processor state at 99% to eliminate turbo and it does not make any difference if I have the graphics settings on high or low.

 

Any ideas or help would be appreciated as I seem to have hit a brick wall.

 

Thanks in advance.

Re: FPS Spikes on Y700-15ISK

Hi there, Chrisk –

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

If the laptop is running on the battery, you will always be facing this problem. You have to run the games while using the power cord.

 

Plug in the AC adapter and set the power settings to high performance

 

Open the power options > change plan settings > change advance power settings and ensure the Link State Power Management is Off and Maximum Processor State is set to 100%.

Download & install GPU Shark (GPU Monitoring Tool) - you should see the GPU clock ~800Mhz+.

Download and install CoreTemp - you should see the CPU clock ~3Ghz+(turbo boost)

 

Also, This could be caused by the nvidia Optimus software. To fix it, simply go into your Nvidia Control Panel >>> Program Settings >>> Select a Program, and switch it to High Performance Nvidia Processor.

Done

 

Update us how it goes.

 

 

 

 

Regards,

Re: FPS Spikes on Y700-15ISK

Evening.

 

So i followed the information and the results were the following.

 

Laptop was plugged in and always remains switched on.

Power was set to "High Performance"

Link State Power Management was "OFF"

Maximum Processor State was 100%

 

Using GPU Shark my Base Clock Speed was 1097MHz

Using Core Temp my CPU Clock was 3490.75MHz

 

Nvidia Control Panel has CS GO set to "High Performance Nvidia Processor"

 

In Game GPU Temperature was 63 degrees maximum with an average of 57 degrees

In Game CPU Temperature was 78 degrees maximum with an average of 65 degrees

 

In Game FPS was 200-300fps  but unfortunately i was still dropping to 50-60 FPS every 5 minutes for about 2/3 seconds causing a spike so none of the above seems to have remedied the problem.

 

One thing i have noticed using Intel Extreme Utility is that it is only using 2 cores where as my old gaming laptop utilised all 4 cores. Could this be an issue?

 

Any other suggestions?

 

Thanks.

 

Chris.

Re: FPS Spikes on Y700-15ISK

On that GPU Shark screenshot, It looks like the GPU is on Power State P0 (P0 = full power 3d) but the GPU clock is no way near 800Mhz+ which is the max clock speed of the GPU. Can you try to check under Nvidia Control Panel > Manage 3D settings > Program Settings (Saints Row 2) and see if the "select the prefered graphisc processor" is set to use "HIgh Performance NVIDIA processor" (see this video in reference)

 

Alternatively, try to use Nvidia Inspector to control Optimus (see this thread). - more info here..

If all these procedures doesn't work, try to update the driver from the Lenovo/Nvidia Website and observe. Last resort would be backing up your files and doing a factory reset to isolate if it's an OS issue.

 

Update us how it goes.

Was this response meant for my post?

 

It's just I didn't upload a GPU Shark screenshot and I'm not trying to play Saints Row.

 

Thanks.

Re: FPS Spikes on Y700-15ISK

Chris, really sorry for posting the wrong query.

 

May be thermal paste between the CPU and the heatsink likely isn't transferring heat properly. Fixing this will require disassembling your laptop and applying new thermal paste. I recommend Arctic Silver 5 or Noctua NT-H1 thermal paste.

 

Please go through this HMM for hardware assistance. Also, if you have to go any deeper then you would be voiding the warranty. I would recommend you to contact Lenovo service center and report your findings.

 

Update us how it goes.
