@ghoul you have to note that your model has got the 750M SLI which doesn't get that hot at all. I tried to fix this only by undervolting but I've either got crashes caused by instability or I've got overheating crashes.

Hello Guys, I wanna share my FINAL SOLUTION for the overheating problem of the Lenovo Ideapad Y510p with you which doesn't include any hardware changes. The used values worked for each game I have, while higher clocks and voltages only worked for some games. 1. Undervolting and underclocking the CPU using Intel Extreme Tuning Utility (XTU): set the Multipliers for 3 and 4 active cores to 26 (reduces heat and prevents throttling) set the Core Voltage Offset to -50 mV these settings won't change after a restart 2. Undervolting and underclocking both GPUs using Nvidia Inspector (NVI): to change the voltage, modifying the BIOS of both internal GPU and Ultrabay GPU will be necessary, this is done by using the BIOS-Mod of Svl7 right here: https://www.techinferno.com/index.php?/forums/topic/3546-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod/ then download Nvidia Inspector: http://orbmu2k.de/tools/nvidia-inspector-tool (Download button is down the website directly above the comments) unzip it and start the file, click "Show Overclocking" and wait for 10-20 second until the values have been refreshed you will always have to wait some time until the values are shown correctly then set the Base Clock Offset to -118 MHz, the Memory Clock Offset to -200MHz and the Voltage Offset to -112.5 mV and click on "Apply Clocks & Voltage", if you have 2 GPUs, select the second one in the bottom left hand corner, do the same for it and apply then you will have two options: 1. you create Clock Shortcuts for each GPU using the button and do apply these setting after each restart or 2. you right click that button and create a Clock Startup Task so it will be applied after each restart automatically (which is much better) I will also attach a batchfile that does exactly the same as the Shortcuts. The values I used should work for each Y510p but you can also try using different ones. I hope this helps some people. The temperatures: - in idle 45-50°C - under load 60-85°C (depending on which game and which settings) overheating fix.zip

This is the time I want to recommend something to every Y510p/Y500 owner (I saw some people on the previous pages of this thread who bricked their BIOSes even after there were so many posts of people who bricked their BIOSes already): DO NEVER TRY TO UNDERVOLT OR CHANGE ANY OTHER SETTINGS IN THE MODDED BIOS IF YOU DON'T KNOW EXACTLY WHAT YOUR'RE DOING! IT WON'T WORK! AND WILL CAUSE YOU SO MUCH TROUBLE...JUST DON'T DO IT! At the beginning of this thread there is a warning: In my opinion there should be said that it's extremely dangerous to change any settings you are unsure about! I want to save you from that **** Believe me

Hey, I'm still looking for stable values for my CPU and GPU's (2x GT755M)... You said you would undervolt+overclock both GPU and CPU... Why do you do that? would it work for me as well? Thanks in advance I didn't fix it yet. It's since I gave it to a computer shop and they fixed it... I would be very glad if someone had a solution and it's a software issue... but I think it could also be hardware related I hope someone has an idea Thanks.

Okay i'll try that... thank you very much for your help before I used some batchfiles from the internet that do underclock and somehow that fixed my problem but I just got 70 fps on Low graphics... no i get 70-90 on High graphics... that's amazing

Did that, I think it works played for about 30 minutes... the temps stopped going up at 81°C and 84°... I get 70-90 fps on BF4 High graphics... I don't know if I could get better performance with a little higher clocks... Where do you know the ratio between the clocks and voltage from? I'm happy for now but of course I want the best performance I can get with no overheating and no instability But thaaaanks so far

So I don't need to change the chache voltage? And yes I underclocked both settings: base clock -50 and memory clock -100 and -87.5mV but overheated. Then I tried -112.5mV and it went up to 86°C main GPU and 92°C at the ultrabay GPU. I was able to play for about 30 minutes but then the game crashed due to overheating (I guess). After that I tried -125.0mV, it didn't crash and it didn't get that extremely hot but after some time I think the performance decreased should I try -100mV as well or should I try other values? I'm actually a noob at that but would be glad to find out values with that I have the best performance and no overheating. I use MSI Afterburner to have a look at the temps and the clocks. The clocks were constant at the value I set them. Any help is appreciated later I can post a screenshot of GPU-z if you want...

Thanks for your help so far, rockyston !! I applied your settings and tested the temps and stability playing BF4 (I always have no fps limit, I wanna stress my GPUs to see if I got stable values and temps won't rise up). First I set graphics to medium and later on to high. The temps were going up permanently but very slow in comparison with the undervolting values before. After something like 20 minutes the ultrabay GPU reached 95° and the main one 90°C, then I stopped. I would be very glad if you could give me a hint which value I should try next or how I should go on Another little question: I undervolted the CPU using Intel XTU as you said... Should I lower the cache voltage offset as well? I do strongly appreciate your help

Ok setting voltages and clocks works now thanks so far!! I tried underclocking by 100mHz and undervolting by 87.5mV, no crashes due to the voltage but it gets very hot (I tested it with Battlefield 4 on Medium settings, no fps limit). I stopped at 90°C at GPU 0 and 95°C at GPU 1. At the beginning I've got between 100 and 130 fps (which is equal to the performance that I get without any changes at the clocks and voltages) and when it got really hot I just had between 80 and 105 fps. How should I go on with undervolting and underclocking? I wanna find values with that I get no crashes due to instability or overheating and no performance loss as well... Do you have any idea which values I should try next? Thanks in advance

Hey guys , if I try to lower the voltages of both GPUs with nvidia inspector (and yes i modded both Vbios and main bios) the slider of "voltage offset" always goes back to 0 if I press apply reducing the core clock by 100mhz works fine. How did you do that? also i don't know which power state i have to choose... would be very happy if you could post an exact explanation on how to do it big thanks in advance Bobbey

Okay my laptop works again after it was bricked, they unsoldered they BIOS chip, then flashed it and soldered again to the board. It works but my little "problem" is that there is a black screen at the startup for about 15-20 seconds which is very annoying. Has anyone an idea how to fix that? Thanks in advance...

Hey guys, I wanna thank you for all your help i gave my laptop to a computer shop and they say it's working again. Thanks, Thanks, Thanks for your help

Thanks and that is exactly what I need are you guys sure it is save to swap these chips and it's going to solve this problem?

Guys it seems like the forum has been updated and the last page of this thread got lost could you please send this image of both BIOS again and Lizzo would you please explain again what I have to do and what I should say to a computer expert in such a shop when I give them my laptop? Huge thanks in advance !!!
