Massive throttling for no reason on my 720s 15IKB

I own the Lenovo Ideapad 720s 15IKB with a i7-7700HQ and a Max Q 1050 TI, I’ve had this laptop for a couple of months, I’ve repasted it with arctic silver 5 which brought my temps down from a max of 96 on the cpu to 85 and a max of 88 on the gpu to 80, I’ve had a issue where when I play games, no matter what game, I’d experience throttling on the gpu and cpu I’m very low temps, I can confirm this is indeed thermal as GPU-Z and XTU states this, I’d start a game on an undervolt of -150mv and an undervolt on the gpu of 1600mhz on 900 on msi afterburner voltage curve editor, all my nvidia drivers are up to date so please don’t say “update drivers” mindlessly, i have an overlay to monitor temps and clock frequencies in game, playing assassins creed oddyseey, the would throttle on the cpu from 3000mhz to all the way down to 1700-1800 MHz within 10-15 mins of gameplay, peak temp is 80, I’m no expert on laptops but laptops aren’t supposed to throttle at this point, throttling is supposed to happen at unsafe temps of 90c + , some cases my gpu core clock will be at 1152 which Is the base and would never boost up even tho the gpu temp Is under 70c, I’ve tested multiple games like fortnite, Rainbow six siege and battlefield 1, every single game would Throttle, even at very low temps, the worst being the gpu which would never boost, if I force the frequency to stay at say 1500 MHz, it would stay at that for around 10 mins, reach a max of temp of 80-82 and throttle, honestly I would’ve returned this laptop if I could but the store I’ve bought it from doesn’t except return or exchange, this is my first Lenovo product and this is a huge disappoint to me to the point that I can genuinely say I will no longer purchase or recommend Lenovo to my friends, to any guys saying “but this isn’t a gaming laptop” that doesn’t matter, I pay for the specs and I expect it to perform how others with the same laptop or even specs to perform, not severely downgraded experiences, I would go as far to call it robbery and false advertising, other people who own this unit have told me that after a repaste and undervolt they never experienced throttling and it would throttle only at extreme temps whereas my unit would sometimes throttle for no reason whatsoever, if any owners of this laptop read this, I’d appreciate any help because I’m stuck with this heap of **bleep** laptop for a while unfortunately, thanks for reading.

 

Alright let me clearify things. Nobody here will ever tell you to update drivers, because we know the newest drivers are nGreedias way of messing with people. Most stable driver I have used is the 391.24.
Also it's important to note, your GPU will throttle no matter what you do, it's a powerlimit issue, which you can't solve unless you plan on getting a hardware programmer and ready to possibly break or make your notebook.

As for the throttlingpoint, each notebook has it's own uniquie throttlingpoint, some start at 98, others at 91, others at 85. I believe lenovo notebooks have a rather low throttlingpoint of 85, at least the gaming legion do have that.

Also lenovo makes excellent Workstation notebooks and decent gaming notebooks, their ideapad series, as you have experienced first hand, are not exacly anything they should be proud of.

Now that we got the most obvious things out of the way, you could download Hwinfo64, start logging and play a game where this issue is happening, preferbly a game that causes the throttling to the most extreme. After you played for a little while, upload the CSV file here in a .zip folder, after that we can see what is causing your CPU to go beserk.

 

hey thanks for your reply, ive started a stability test while playing a game, once i finished playing i clicked save and it saved a png? sorry there wasnt a CSV option.....
EDIT: i realized i download aida64, sorry about that, will download HW now

 

i cannot post csv file as there is no attach file option for me

 

thats why u have to .zip it into a zip file, this forum only accepts zip files.

when making a post you have an "upload a file" button.

 

Im sorry but there is no option attach any file whatsover..............

 

Well you could also upload it in an external service such as file-upload.net

 

Have you tried disabling BD Prochot via Throttlestop? BTW, this model has undersized charger issue

 

I was able to experience all of what you stated and the CPU cannot be fixed.



The GPU can be tamed and it’ll take some more tweaking.

That video above should clear up a few things and there’s 3 more in the playlist associated with it. But you’ve likely seen these if you have been looking for a solution.

 

I recently got this laptop and last night noticed that while plugged in and gaming the battery was slowly discharging. It had a full charge and was plugged in and after about 2 and half hours noticed the battery was down to 84%. After exiting the game and using for web browsing it charged back up. Is this normal or a defect?

 

By design.... See MSI in full bloom @Falkentyne
