Intel i7-7700hq undervolt for ntb

[Ghazghul Thraka]

Hello i have a notebook asus rog gl553vd its old really old (2017 last produced). When i first gott this ntb it couldnt even run google without getting up to 100 C, it had a single stick of 8gb ram, and the airflow was limited thanks to intakes on the bottom. After getting the second ram stick installed the pc was 50% faster at everything. Now the ntb ran at 100 C even on desktop (im cleaning laptop cooler every 6 months with compressor even taking apart the cooler and fins) Then i found Throttlestop, after turning it on pc instantly wwent down to 35 C. Now it overheated only when playing games. the performance was still only 50% since i wasnt getting more than 60fps in apex legends at 1080p. After 3 whole days of fiddling and stress testing with core, cache voltages i have managed to get my cpu to run full tilt at 86-7 degrees max under stress. but there was a difference of 10 degrees bettween the fastest a slowest cores. i had to repaste both the gpu and cpu since they are in a single heatsink, cpu was under heat pipes while the gpu sat under heatsink. the cpu paste was solid and crumbly and gpu had only a thermal pad. i used arctic mx 4 thermal compound on the cpu and left the thermal pad as was. Now the ntb doesnt get hotter than 85 C even when running games. Im posting this bcuz i had so many troubles with this ntb and i didnt find any helpful advice online. This ntb wasnt worth it at all, even though it was 1000 bucks (8 years old). Now its worth it but i had to open the ntb in its first year for multiple cleanings, cut open the plastics for bettwr airflow, cooling pad, changed thermal paste, and had to undervolt for multiple days. Simply put Notebooks are worth it if u are gonna put the work into them. Also uncleweb if ur reading this thanks so much for ur program this pc probably wouldnt even work now also are those core/cache values even possible ? idk but whenever i tested it i had no errors nor anything and the wattage is lower than before, Did i win the sillicon lottery ?

Try using ThrottleStop 9.7.2

Did i win the silicon lottery ?

Maybe.

You definitely have a chip that is happy running at a very low VID voltage. Rare to see one go under 0.6 V. That looks more like the kind of voltage a low powered netbook computer would use.

Low voltage reduces power consumption and heat output. This allows a CPU to run cool even when running a full load stress test. Four core CPUs that run at a very comfortable temperature are perfect for the majority of laptop owners. I still like my 12 year old Lenovo Y510P which has a four core 4700MQ. Newer laptops tend to run at over 90°C. That is not very lap friendly.

I prefer setting IccMax to the max for the core and the cache. This is probably not necessary but I like to do this anyhow. This might reduce EDP lighting up yellow under the RING column. Often times, EDP lights up yellow no matter what you do.

are those core/cache values even possible?

Those sliders let you adjust the core and cache offset voltage request values. The cache offset is the important one. Cranking the core offset more than 100 mV greater than the cache is usually mostly ignored. Some people can set the core offset request to the max, -1000 mV. Obviously the CPU is not actually reducing the voltage that much or else it would instantly crash. That is why I tell people that it is just a request. What the CPU decides to do with your offset voltage request is up to the CPU. It will automatically ignore a core offset request if it is set sky high.

Well i have been trying those cache and core values for more than a day and the cpu seemed rly happy when i put the core value around 50% more than the core value, is it possible that its working at that given value ? or is it choosing its own core value ? If i put the cache value even one step higher the cpu starts putting out hundreds of errors, core value didnt affect the error amount at all. can i somehow boost this cpu performance even more ? (tdp of this chip is 35 xD ive managed to get it to 37.8 i think but that was after a day long stress test with games) is there any reason i should get the version of TS ? i have it set to start up with windows and im afraid its gonna brick that

No one knows what voltage the CPU is actually using. When you increase the core slider, you will always reach a point where increasing the core slider more will not make any difference to performance, power consumption or temperatures. No one know what that magic point is. Every Intel CPU is different. That is why it is always best to experiment. Some Intel CPUs do not decrease power consumption or temperatures any as soon as you increase the core offset any higher than the cache offset. These two voltages are sometimes synced internally so they are both coming from the exact same voltage rail within the CPU.

Using different offsets seems to be a trick to get the CPU to lower voltage when it is running a lot of AVX instructions. Cinebench R23 is a good test to confirm if using different voltages is a good idea or not.

tdp of this chip is 35

The 7700HQ actually has a 45W TDP rating. The TDP number is not that important.

Newer versions tend to have a few more features. Old bugs get fixed and new bugs are added. That is true for all software updates. You can use whatever version you like. I like new stuff.

If you download the new version, unzip the download and copy the new ThrottleStop.exe into your existing ThrottleStop folder. That should not cause any problems.
