Is it worth it? I'm actually considering buying the Y740 and this helps alot. For comparison, I've tested Shadow of the tomb raider using the benchmark test on highest setting preset running on bios 1.06 and 1.03, with the following tweaks/tuning (do not blindly copy my settings/values, find your own own optimal values using software like aida64, heaven benchmark etc. In fact they mostly stay around 68-71c even under load for significant stretch of time which is super impressive. )If you've purchased the 9th gen variant like me, most probably you never had the max fan option to begin with. if -60mv was stable, try -65mv). if it froze at -60mv, lower the UV to -55mv) and try again until it’s stable. I'v never done it do i'm a noob in this subject and i dont know is it worth it. After I check the box of speed shift EPP in throttlestop, set it to 1, run aida64 for like 10min, shut it down and uncheck that box, CPU clock speed and temperature seems to behave normal now. Going to copy some of your settings. Let me know if there's a better way to combat PLT. Temperature is unfortunately of no difference. The last and the only available bios version, that supports the max fan option for the 9th gen models, is the version 1.03. I've seen a lot of discussions online about the max fan option being removed from the laptop earlier this year and yeah it sucks and I really hope Lenovo brings back the choice through a future update but at this point, considering their silence on the matter, I don't expect much.But there's a couple of things I'd like to make clear. I've searched similar issues in the past two days. The gpu temps mostly stayed between 58 and 70 and the cpu temps ranged between 70-85, which really makes the downgrade worth it. Nonetheless, I hope I am able to get my point across- y740 is an amazing machine with great thermal design. The y740 chassis is very capable of dissipating heat and maintaining very decent temperatures under load with no throttling but lenovo has intentionally made it difficult for the user to get significantly better temps, by removing the max fan speed option through bios updates. Skip to the end for the settings, results and conclusion. (17 inch version) While the machine is pretty cool and quiet during daily use (including gaming), my CPU temperatures during both combined CPU/GPU stress test and CPU stress test seem to be higher than they should be, when looking at reviews and reports from people with this model. I'm hoping a repasting will improve this in near future. I can apply for return and refund in 30days after package arrival but they require a testing before actually fulfill the refund. Dell G3, I5 9300h @ 3.95 Ghz locked, 8 GB DDR3 RAM, GTX 1660 ti. Y740 is not one of the laptops with mediocre/bad thermal designs. While it may vary a bit from laptop to laptop but I'm sure as long it's not a defective product, you'll get great gpu cooling. see if anything is maxed out there? Also check if there are any idle processes in the background, Thx for the advice. New comments cannot be posted and votes cannot be cast, More posts from the GamingLaptops community. These let you switch between different profiles, each of which can have its own undervolt settings. And if you have a beast mode GPU you might be okay. Just browsing reddit, after gaming for a couple hours I'm at 45c. This is running at setttings twice than of the PS4 and at 30-80 percent of the FPS.... Amazing. So undervolting is a viable fix. My personal preferences with a Y740 and 9750H are -150mv core and cache undervolt, power slider on better performance, and all 6 cores set to 3.5Ghz. But absolutely thrashes the base PS4. Hi So i recently bought a Legion Y540 with i7-9750H and RTX 2060 and i'm wondering can i undervolt cpu and overclock gpu. 800mhz at idle, 30-40 degrees. Compact, portable, powerful gaming laptops! The best case scenario according to me would be that lenovo rolls out a bios update that doesn't change the tdp of cpu or the thermal modes, but give an extra hotkey which when enabled in the vantage software, allows the user to ramp up the fan to max speed at the press of a button and ignores the thermal mode, allowing best performance at the price of constant fan noise. After overclocking the gpu as well, the average fps increased to around 83. When running Aida my temps run at 84 average with spikes into 90C +. About 60C after undervolt in G SYNC mode. So far my experience has been great and even testing on cinebench r20 which is very cpu intensive, the laptop doesn't go beyond 84c (with undervolt applied). However, here's the crazy part. If the system has no issues after a few hours of testing, then go ahead and lower the voltage offset a little more (i.e. But yeah. [Guide] How to take full control of the i7-8750H (Advanced version) @unclewebb @Falkentyne @raz8020 Greetings fellow members, If you are looking for full control in Windows over the C-state and the multiplier in the Turbo boost mode and … BTW does lenovo have chat support? I purchased the legion y740 15IRH with rtx 2060 and i7 9750H sometime back and have been playing around with various performance tests and tweaks and I felt that some of the things I learnt while doing that might be of some help for someone who either owns a y740 or is planning to buy one. Buy Lenovo Legion Y740, 15.6 144Hz, Intel Core i7-9750H, NVIDIA GeForce GTX 1660 Ti 6GB, 16GB DDR4, 512GB SSD + 1TB HDD at Walmart.com I've seen other people have amazing results on their y540 on cinebench too. Hope that´s the solution :D. Could it be a windows issue ? The gpu cooling is just amazing out of the box. My rtx 2060 laptop manages to perform better than laptops with full rtx 2070 running at 115W at stock settings and almost at par with the 2080 max q laptops. This sounds like a big deal, but doesn't make any difference in gaming performance since during cpu+gpu load, both have same cpu power cap. What are your temps and cpu clock speed during the cinebench r20 test? As I've mentioned, lenovo has done a great job with the gpu cooling. Your laptop perform better than his 2070 because you tweaked the settings, at the same graphic settings a 2060 will never beat a 2070 even with a big OC. Lenovo komt met een fix. https://support.lenovo.com/us/en/downloads/ds506181, that's for the y740 ICH/ICHg which is the 8th gen processor variant.

The bios version that they're shipping out most laptops with is 1.07 but on their website, the latest one available till now is 1.06 (again, this is not the same as the 1.06 version of 8th gen variant).

I've used throttlestop to undervolt my CPU core and cache by -147.5 mV.
