Re: Thinkpad E590 - Radeon RX 550 performance issue

I purchases Zalman ZM-NC3 cooling pad. It does the trick...

Basically, the laptop is now able to operate on full load without any throttling.

 

Still, this is not really a solution.

What about downgrading the BIOS Version? I read that downgrading to Version 1.08 helps a little bit. Does anyone know how much of an improvement it makes? And what are the downsides of doing this? I read all the README files and there are a lot of fixes since Version 1.08

To Mooko: "Reverse BIOS" solution (on own risc) solves problem of E580, where B1.14 came with "advanced thermal management", meaning "drop GPU core to 200MHz and wait untill it cools down itselves" aka throttling. So E580 with B1.13 (and pre) has no throtling, but easy overheats over 80°C, highest achieved are about  86°C. E590 comes after E580-B1.14 (April 2018?) so there are no "pre-ATM" BIOSes - neither 1.08. It is possible some (older, or even future) BIOS has slightly diferent "ATM" function, and thus throttles "softer", but none of them has been approved as fully no-throttling yet.

I read about undervolting my i5 and then i realized, that there is an "Lenovo Intelligent Thermal Solution" driver installed. What happens if i delete it? Perhaps then the throttling is gone. xD

It’s really disappointing  how this thread is going one sided (customer), I remember when Lenovo representatives were trying to shut it down early enough but failed as there failed design and stupid remediation (throttling)

I made the mistake of buying the E590 a few days ago without researching all the issues it had. Now I'm thinking of returning it. Not that I'm a gamer but when i buy something I want it to work properly as intended.

I documented a similar problem related to E590 with RX550X, and it looks like there is a workaround that applies to that issue. Check out this post:

https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/E590-with-Radeon-RX550X-CPU-power-inconsistent-after-reboot-Bug/td-p/4571503

 

Curious whether the workaround solves the problem in other use cases.

 

P.s. there is a fresh BIOS update (version 1.20) that ups the power limit of the CPU package in Best Performance mode, providing a major performance boost (along with higher temperatures of course). However I could only see the boost when applying the workaround described in the linked post.

The new bios together with the workaround is a good solution, i managed to play a while today with this solution.
