Sorry for the delay, in fact my motherboard had some problems in the GPU part so I had it sent to service, and they ended up swaping the entire board, I'm now testing with the new chip to see where I can get the sweet spot. As far as I know you are just taking power from your cpu to avoid the overheat and the thermal throttle that comes with it, for what I read around it is quite safe and won't void warranty. Altho you are taking away power from it your are getting perfomance since you avoid the big cut of thermal throttle. Also you can check this guides, takes like 20min for both but you get a ton of information about the process: I'm also a noob in this area but you can see the huge improvement, you can go from scoring 2600 in cinebench r20 to 3000-3100 just by avoiding that massive thermal throttle. Goodluck with your unit ^^ PS: Remember that every unit is different, so don't use the values I used right away!

I just did it and seems there is an obvious difference. I was trying some configurations and I guess I'll go for the -70 Watts for now, but it's nice to know where to get a little extra juice if I ever need it. Had to up my undervolt on cache from -.180 to -.175 since I got a blue screen (Two Point Hospital seems to be a great stress test for this). Results with 75w -.300mv core -.175 cache Results with 70 Watts -.300 core and -.175 cache After picking the 70 Watts setup I went and changed the Core to -.175 and the cache at -.175 and got a decent decrease of performance Just realized I forgot to take a screen of the AIDA test with this last config but It had a lower CPU boost speed.

Thanks for the super detailed reply! I did as you said and tested again with the previous configuration to check the Limit Reasons with the 70 power limit and after doing what you suggested I got rid of the red throttle warnings but got a thermal yellow. Managed to get 3149 in the benchmark as well with this change.

Hi, I got a Lenovo Legion Y540 I7-9750h, rtx2060, 16gb ram recently and I've been testing around with Throttlestop since it gets so damn hot from stock (I'm new at this). I was following a guide that says that we should leave the Cache undervolt at -.125 and just test around with the Core to the max possible. Today I went to try and mess with the Cache a bit and went up to -.200 where it gave me a blue screen in idle, no problems with the benchmarks, after that I tuned down to -.175 in Throttlestop that actually shows up in HWmonitor as .-180 and so far so good. At the moment I have a -.300mv on Core and -.180 on cache but I've read around that intel takes on the same for both so I guess I'm at -.180? I've ran cinebench r20 a few times getting 3100-3120 score range. I've also attatched a screen of my current configuration. The throttling shown in the stress test is right when I start it since the fans are not at max power. TL;DR If you guys can take a look at my config and tell me if I'm messing up in some point I would appreciate it. Thanks!
