m18x2 - 980m - win 8.1 - throttling on all new drivers

so ive been using 980m + windows 8.1 + 353.00 drivers from this stie for many years now

every single new driver version ive tried throttles in games - the only one that doesn't is the Mr Fox 353.00 one which must be close to 8 years old by now

can anyone assist? - is there a new driver version that has been modded to prevent throttling?

im holding out on upgrading until they come out with another 18" laptop

 

probably a long shot, but perhaps it might be due to 8.1? have you tried windows 10 or 7

 

To prevent throttling, you must have the A11 unlocked bios. You can get it from here forums.

After flashing the A11 Bios, upon powering your laptop, enter BIOS and under Advanced Oprions, Select Video Configuration.

Select IGFX and save and exit.
Restart
Enter Bios again
Go to the Video Menu
Select PEG
Boot to windows.

Throttling Removed

 

There is still no way to avoid doing that every time you want to play?

 

As long as you don't disconnect ac adapter, you don't have to do it.

This is why I gave up SLI and went single GPU + NVMe MXM board instead

 

So I have the single MSI GTX 980 from the Titan in my M18X R2 and sometimes if I have overclocked the CPU I get throttling all I do then is removed the CMOS coin style battery and hold power down with no power supply or battery installed for 30 sec and there we go problem solved .

The MSI GPU has been vbios modified and will draw around 170W whilst gaming

 

Hello, I was wondering is it worth putting sli gtx 980m into m18x r2 laptop? how much performance does it adds?

 

Should be awesome for games that support sli or crossfire roughly 30/40% performance boost when in sli ... I have a few 980m sli clevo the P870DM and P375SM both awesome for older titles

 

so there is no solution for gtx 980m throttling? just always need to change bios and restart?

 

I have not found a solution for this problem in sli

 

I have had this issue also, so what I did in WIN10 i have enabled the Ultimate performance power plan, it allows to draw as much voltage as it needs without any limitations, and I did not have to always change IGX to PEG, unplugged the laptop from power cord, plugged power cord again, turned on laptop and it seems to be working, no throttling. I have a single gtx 980m. so changing power plan to ultimate performance fixed throttling for me.

WIN 10 do not have this option enabled by default, you need to run this command in POWERSHELL(not cmd) to enable the power plan.

powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Check it, maybe it will work for you as well

[EDIT]
I am using newest NVIDIA drivers, OS is WIN 10, BIOS A11 unlocked(did not change anything in bios), cpu 3740qm, ram 32gb
also in Nvidia control pannel, set the power plan to ADAPTIVE

The throttling thing itself is more a SOFTWARE issue, not hardware. Also try to downgrade your gpu CLOCK and memory clocks to test if downgrading them removes the throttling.
