GTX980m unstable performance problem (Clevo P770ZM)

Hello people. I am having some problem with my Clevo P770ZM, and I really need your help.

When ever I play video game, I always prefer to have solid 60fps. Therefore, when I buy any video game, I go to video setting menu, and change the settings, than boom, I have solid 60 fps.

However, there are some moments that I sometime get 40 ~ 45 fps, for no reason, I did not change the video setting, and when I unplug my charger and re - plug it, the frame rate rise up to 60 fps again.

I've checked gpu -z and found out that when this happens, the gpu clock speed is around mid 800 ~ mid 900 mhz, which is 15 ~ 20% lower than typical boost clock, 1126mhz.

Also, this does not happens when I use 352.84 driver, which is the earliest driver. Anything other than 352.84, there is some performance drop - even 362.00 driver. Can anyone help me? Thanks

PS: I am currently using windows 10 pro.

 

Probably throttle. If you are already using the Mod then it can only be temperature induced.
If you are still using the factory vBIOS, just click my signature and flash the mod version of the MXM vBIOS and it'll be fixed.

 

The temperature of the gpu is around 60 ~ 70 c, so i don't think that is the problem. Also, I might contact my Clevo reseller, and try to change the gpu. If that doesn't work, than I will change vbios. Changing the vbios is the last step that I will try, since I've never changed any bios, and there is always the posibility that I screw up, and have a brick, instead of a laptop

 

ALL stock GPUs will throttle, you can change them a million times...it's their default behavior.
If you don't want these dips to happen then you will have to use a mod...that's why we make them.

 

MSI afterburner will give you a clue as to the reason you are getting reduced speeds, it's worth looking at your CPU temperatures too.

 

Why waste time replacing a GPU when it might be perfectly fine? Prema is telling you the easy solution. If that VBIOS trick doesn't work, then you should send the laptop back for a GPU replacement not the other way round.

 

I've never changed vbios before, so I am kinda worry about screwing up. Also, the clevo reseller that I bought from does not allow to change either bios or vbios.

 

I cannot count the times that I have switched between stock and prema VBIOS, it literally takes a few seconds.... but it's up to you bro

Before doing this, save your stock BIOS using GPU-Z and place it somewhere safe in case you want to go back to stock for warranty claims in the future

1) Extract the VBIOS folder and place that folder in the root of C: for ease of access via DOS

2) Rename the folder to an easy name like VBIOS

3) Launch Command Prompt As Admin

4) Open Device Manager, find your graphics card, right click on it, and select DISABLE

5) in the DOS Window, type cd\ to go back to the root of C:

6) Type cd VBIOS (or whatever folder name you renamed the VBIOS folder to)

7) type modme then hit enter

8) you will then get a prompt if you want to confirm, press Y then hit enter

9) wait for a few seconds till you get a message that the flash was successful and a reboot is required

10) go back to device manager and re-enable your graphics card

11) reboot and enjoy

 

Wow.... Thanks for all the help mate!! I will definitely try this method

 

Remember when flashing not to have programs like GPU/System monitoring applications running.
