If you want to give it a spin, ThrottleStop can be downloaded here. a lot less lagging + stuttering inherent to Lenovo’s stock thermal management. These 6-8Â☌ difference + constant Turbo Mode are especially great for playing occasional games on the device as there is more thermal headroom for the IGP to use, i.e. Battery draw on load is roughly 1.5 Watts lower: 7.3W versus 8.8W Turbo Mode VID set to 0.575 V (0.055 V lower), which I found to be stable on my device:Īs you can see temperatures are 6-8Â☌ lower with ThrottleStop enabled – and that is with Turbo Mode constantly on! There is no throttling happening like with the stock CPU management. CPU heat/usage) with the stock clocking and CPU management. Naturally I was eager to test ThrottleStop on this device, knowing it was able to lower the voltage (Voltage ID/VID) of the Z530 CPU on my Fujitsu U2010, thus reducing the overall power draw + TDP of the CPU.įirst off, here are the results running prime95 (64-bit, Torture mode, Small FFT, max. While the Lenovo Settings tool offer a hard to find/enable “Cool Mode”, it doesn’t do much to lower the temperature and battery consumption. Lenovo’s thermal management includes heavy throttling/down-clocking of the CPU to stay within the bounds of TJmax of 105Â☌ of this CPU. The Intel Atom Z3795 CPU gets quite hot when under load. The Lenovo ThinkPad 8, while being a good performing mobile warrior device, is not known for being cool and conserving in terms of battery usage. It recently came to my attention that ThrottleStop, a utility I had been using previously to undervolt my Fujitsu U2010 (Intel Atom Z530), is now finally available with support for the Intel Atom Z3xxx Bay Trail CPU series (used in Lenovo ThinkPad 8, ThinkPad 10, Dell Venue 8 Pro, Asus VivoTab etc.). At full load the temperatures of my ThinkPad 8 are 6-8Â☌ lower, 1.5W less power draw, always-on Turbo Mode. TL DR: Support for Atom Z3000 series in ThrottleStop is amazing.
