Did you just set -140.6mV on Cpu Core and CPU Cache? What about intel GPU?
I have the same specs as you and tried -130.9 but got freezing while playing BF1 a few times.

Thanks

 

The differences in undervolt will vary chip to chip. I used the same undervolt for both the CPU core and cache. It really sucks that we have to go through these hoops but that's life

Ah okay.
Thanks for the clarification.
Yes it is unfortunate that we need to go through to these lengths.

I'll try some different voltages out thanks

 

Hi, sorry if I'm hijacking the thread a bit, but I didn't want to open a new one.

I have almost the same issue as @Matthew Gary , but I have a Clevo P650RS with an i7 6700HQ, the rest is the same. While playing Overwatch, I managed to reach pretty high temperatures on maximum graphic settings, without a cooling pad, on automatic fan speed.

CPU peaked at 91 C°, with an average in the high 80s, and GPU peaked at 88 C°.
I guess this is not normal, even if my CPU is an older generation, so I undervolted my CPU by -150 mV, and used the laptop normally with a cooling pad, which brought down the temps to CPU in the mid-high 70s, GPU in low 80s.

My question is, should I expect temperature drops if I repaste with a new paste? I've ordered the computer with Thermal Grizzly Kryonaut, and I'm planning to use Noctua NT-H1 for repasting, with the help of an official laptop repair shop, to be sure not to void my warranty.

Also, does anybody has reliable info on the temps I should be getting, while playing different games on maximum settings?

 

With your undervolt the temps don't look so bad. Doing the undervolt has worked magic with temps as well as repasting, more so the undervolt though. In games I run roughly the same temp as you are now, in the mid 70s. I also re-pasted from standard thermal paste to the Grizzly. I think the only way to really bring the temps into line would require an additional copper line (for a lack of a better word) running from the CPU heatsink or maybe incorporating a duel fan config similar to the GPU's setup since the GPU and CPU share heat dispensing. As long as the GPU isn't being taxed the CPU temps stay decent.

Hi guys, I have the same Clevo P650HS-G, 7700hq and gtx 1070.
my GPU temps are very good, they are lower that 75C most of the times but the CPU temps are going mad, I have played CSGO for a couple of hours and it hit 100C on two cores.
but this is happening in other games too: BF1 or GTA V.

I have not undervolted or changed the thermal paste yet.
I have an Arctic MX4 thermal paste, a pretty old one, i could always buy some more.
I was wondering if I should try undervolting the CPU first (never done anything similar before, usually I overclocked the CPU on my desktop) or change the thermal paste.

I have had this laptop for the last two weeks, I like it so much, I have been playing games and i am more than satisfied by it, but the CPU temps are scaring me.

please help!!

 

Definitely try undervolting, it may bring your temps down to around 90 C°, and it's really an easy and effortless thing to do. Just google undervolt, or throttlestop undervolt, and you will find plenty of guides about it. Just make sure to thoroughly test your CPU (and GPU at the same time to experience the normal stress of games) with something like aida64 or prime95 and furmark. An undervolt of -100mV should be easily achievable, even something around -150mV should be.

Even with an undervolt, if you are worried about your CPU you should get a repaste. I had my laptop pasted with Thermal Gryzzly Kryonaut, which I think might have been applied incorrectly, but after repasting with Noctua NT-H1 at a repair shop, my temps are much more in line with the expected numbers.

Also, get a good laptop cooler. The difference can be day and night between having one and not having one.

 

thank you for the prompt reply Brabulla. i will try everything one by one and keep you guys updated.

 

I have it with -126mv and ic7 and getting 70 cpu and 73 gpu full speed (full)

Looking at what I have, that is really impressive?
but isn't undervolting affecting CPU performance?

 

Brabulla, I am not that confident in the laptop cooler solutions. I mean, even if I am to buy one, I will not be able to carry it around with me, and as far as I understand that is only 5C decrease at the most.
I think I will rely the most on undervaluing and changing the thermal paste.
do you think I should go with the MX4?
https://www.arctic.ac/de_en/mx-4.html

Also, isn't undervolting going to affect CPU performance?

Thank you so much for your help.
i will post some pictures as soon as i will get around on working on it.

 

I havent seen any difference except the temps, i recommend u ic7 or thermal grizzly than mx4 (i had mx4 but its better ic7)

Also what u can get a minus c on the laptop is a notebook vacum (ebay or amazon)

Hi all!! i have good news. i have changed the thermal paste and guess whqt, only -C over the 100 that i was usually having in cs go or gta v. an improvement but not much. changed the voltage to -80 and it is already better, 10C off. i am more than ok with that.

my ram was not running at 2400, it was running at 2133. changed only the memory multiplier to x18 and now it runs at 2400 as it should. i dont know if it is the right think to do but it runs.

i have tried to go over -0.110 with the voltage, it does not like it, even if it increases in performance and the temps are way better. i believe i am gping to stick with -0.90 for now.

i am using intel xtu
can someone tell me what you have for memory profiles?

i have cmd: 2t
tcl:15
trdc: 15
tras: 36
trrd: 11
twr: 16
trtp: 8
twtr: 0
trfc: 374
tfaw: 23
memory multiplier: 18x
memory voltage: 1.200V
memory clock multiplier: 1.33x

i dont want to fry my memory

also, in the ixtu benchmark inscore 646 with de settings above. is that normal?

 

646 in XTU means crippled score!! Even for the former 6700hq.

 

how much do you get?

 

I don't have BGA!! But your XTU score is on level with a 5 years old obsolete Ivy Bridge mobile i7

 

Double post

 

After giving it some time with my 8157 and not seeing the temps everyone else is seeing after these fixes noted above, I feel like I needed to get some outside help, especially since it seems Phoenix has been able to help some.

I got mine from XOTIC w/ the ICD paste, and immediately noticed higher than normal temps (high 80s - low 90s). So I set up a profile in Throttlestop and undervolted to -130mV and it seems to have worked for a while. Now I am experiencing +90C frequently when gaming/streaming in both CPU and GPU and I've no clue why. I wasn't happy with the temps I had before, but now it is completely unacceptable. I considered re-pasting but I am trusting XOTIC did the right thing and actually put IC Diamond as my paste. So that aside, and using TS to undervolt, it seems I've reached a dead end.

I wanted to test XTU so I stopped TS and setup a profile in XTU to -100mV. I stopped TS and played a round to monitor some PUBG gameplay for 30 minutes (idle, to opening game, to intense gameplay) and have it posted here. It sat mid 90s pretty much 3 minutes into the match until I finished and shut the game down.

I will be defaulting XTU, starting my TS profile (the -130mV profile), and doing another round of testing now. Will post those results after.

Any help is appreciated!

 

Ivy bridge is not obsolete which is nice in a way and a bit sad in another.

 

Here are the results w/ a TS -130mV undervolt at the very end of a PUBG round.

I took some things XTU was monitoring out so it doesn't look so crazy.

To clarify, this is both CPU and GPU with the GPU temps being slightly higher most of the time

 

I should perhaps used a better word than <obsolete>. A 5 year old Ivy Bridge mobile i7 can still compete with today's BGA. In the same way as a +4 year old medium powered Hotwell i7-4810mq will crush i7-6700hq into the dust in bench. It's also equal in performance vs. newest of Intel's so called high end mobile i7-7700hq. With some love will the older 4810mq throw 7700hq down the hill in benchmarks.

 

So I have the same laptop as OP
Mines:
Sager NP8157 (Clevo P650HS-G) - 15.6" FHD IPS Matte Screen w/ G-Sync Gaming Laptop Intel Core i7-7820HK GTX1070 16GB DDR4 Samsung 512GB NVMe SSD 1TB HDD Win10
And I'm having the same heat issues as well, playing games makes my CPU go up to like 90-97 once it touches the 100s, so can anyone help me do the undervolt thingy since I'm not that good with that kind of stuff? ><

 

I didnt know how else to contact you, but would you be so kind to help me out with my issue too? :/
Its been like 2 weeks since i got the laptop and the heat issues are insane ><

 

do u have stock TP ?? if u do, try to change it to IC7 or Thermal Grizzly

try throuttlestop (just youtube how to use it), its easy and i got very good results

I suggest you buy some Grizzly Kryonanut and repaste it yourself. Stressing over this isn't going to help you. You should not be getting those temps.

 

I just got my Sager NP8157 last October this year. IC thermal compound on both CPU and GPU. Playing PUBG on a mixed Low, Medium settings and ULTRA on view distance, full screen 1920x1080.
Both CPU and GPU temps are playing on 85 to 93 degrees celsius.

Here's what I did to at least lessen the temperature when playing.

1. Intel Extrem Utility Tuning (XTU)
-Under volted with -0.120v
-Disabled Turbo boost
-On Power Options, Change plan settings, Change Advance power settings, Under Processor Power Management, set the Maximum processor state to 80% instead of 100%
-Test first with -0.110v
-Do a stress test for 5mins
-If stable and test passed, increment by 5, -0.115v
-Remember that every unit is unique, but the common undervolt I'm seeing for i7-7700HQ is -0.110v
-I just went with -0.120v as it was stable for me. Others can get to -0.130v up to -0.140v
-Remember volt should be on negative, not positive -0.110v

2. MSI Afterburner for frequency and curve
-1785Mhz @0.843v

Now I'm able to play PUBG with the temperature playing between 60 degrees to 72 degrees celsius both CPU and GPU

Playing Dota2, NBA2k17, Need For Speed Shift, Assetto Corsa now just gives me 55 to 63 degrees celsius.

Hope this helps.

My last hope would be to do a re-paste of the thermal compound if ever the temp issue persists. So far it hasn't reached 90 again when Im playing for long hours.

Hi @borys991
What software are you using to display FPS and temperature details?

 

I seem to be getting the same issue. Idling in the 40s but it jumps to 90+ and sometimes stays there during gameplay. Currently downloading some benchmarking tools to make sure it's not a graphics issue, but I expect I'll see a CPU bottleneck and have to undervolt and repaste down the road. Shame.

 

Appreciate this is an old thread but this forum routinely offers an inaccurate view of expected temps with these gaming laptops.

They all thermal throttle like crazy, and they only do that in the limit of 100 deg C.

Any game that gives the cpu a workout (and a lot don't) will throttle. It's entirely normal.

 

Hey @Phoenix. Please can you help me undervolt/Mod my i7 7700HQ CPU. I have undervolted CPU core -115 mV and Cache -120 mV but temps are still in early 90's. What else can I change in Throttlestop to reduce temps without sacrificing performance. Thanks

 

I no longer use Throttle Stop since ages bro. Your best bet is to ask the same question here: The ThrottleStop Guide

 

Learn How to Lower Temperatures, Stop Throttling, etc with ThrottleStop

No the need for more than 1 power profile? Or is Xtu in your toolbox? Maybe you use different power plan with different settings put in Win advanced power plan?

 

I have not the need for any software controlling my taptop and I also have not the need for an app that can't get its freakin' notification icon to show up in the taskbar properly nor does it have a simple button to create an automated task for it to start automatically at startup. I know how to create a task but such basic things should be part of any app.

 

Not much more work than stop the OEMS Bloatware from running at Win start up with Autruns.exe
And as you can see in images from the BGA-KILLER, the lovely TS icon stay put where it should be

ThrottleStop is an amazing tool for me to control/check out if others have clock speed problems, aka wrong or crippled Cpu performance (Benchmarks). Just put in their Cpu clocks in TS and this is done within 5 sec

 

Holy shizzzz i came in here with the same overheating problems, didn't know what to do. Went from swapping thermal paste, to liquid metal then back again and nothing worked. I gave up and tried a tip in this thread from the guy that said he undervolted and removed boosting and then i had the idea to watch a couple youtube vids and found one on dust build up but i thought it wasn't the problem because i was always tryna blow out all the dust but i did it completely wrong. I should have blown out the dust from the vents on the side and the back for the cpu and gpu and not directly into the fans. now with everything dusted and the tips from the guy i get really low temps while gaming. Was touching 96 on the cpu and 90 on the gpu while gaming, now i get low to high 70s on the cpu and low to high 60s on the gpu

 

Air duster in both directions and hold the gpu fan from spinning Glad to hear its performing well.
