So, turns out the expected delivery date is accurate. It just got marked as being on truck for delivery.

Yes the tracking seems to be correct. I finally got mine like an hour ago just like the tracking showed.

So it turns out using ThrottleStop to run at Windows startup, and a slight undervolt and enabling built in Intel Speed Shift nets a 40% improvement in performance when only the CPU is stressed.

You can change the Speed Shift value if you want the CPU clocks to be pinned at max during most types of load by setting it to 0. I would only use that in your AC profile though when the laptop is plugged in so it doesn't chew through the battery.

Those with orange tint issue, is your panel "M140NWF5 R3"? Anyone contact Lenovo about this?

Does that pin the CPU at 25W though? I would imagine that the motherboard circuitry is only designed for a 15W constant load.

I should clarify "max"; as I meant in the context of most normal load situations, this would mean the base clock frequency. Going over the 15W TDP limit would mean the CPU is in Turbo Boost which is reserved for the most demanding loads in short bursts and is governed by a time limit as well as the thermal headroom available.

In other words, setting the Speed Shift value at 0 just means that it's going to be operating at it's base clock frequency and won't down clock in low load situations like idle. This will make normal use feel more "snappy" as there's no delay in waiting for the CPU to ramp up it's clock speed when it detects a higher performance state.

Thanks for the clarification. I'm just going to let the CPU run as low as it can during idle to improve battery life and let it use the full 15W during sustained load and leave the 25W for up to 28s as default. Speedshift is supposed to address the CPU ramp up very fast so it should feel very snappy as is.

Same with mine. All Fedex shows is that the label has been created. Was supposed to be delivered on the 12th.
my label was created on sunday with the wednesday delivery but it was picked up on wednesday from BC and arrived today in the GTA.

BTW anyone interested in buying another one? my sister said it looks ugly from the pictures ahahaha. I believe the return date is jan 31st yeah?

Did you guys using ThrottleStop mess with the Speed Shift EPP value? The guide says to use 64 for the performance profile, however I can't seem to find how to modify this setting. It's on 128 on all my profiles.

Edit: Ok, clicking on it allows you to change it even though it doesn't show a box or anything like you'd normally expect when you can change the value.

Click on the "128" and you can edit it. Also make sure to click on the TPL button and check off boxes for Enable Speed Shift and Enable Speed Shift when ThrottleStop starts

Everest tells me I also have the M140NWF5 R3.

I also did a benchmark after I setup Task Scheduler to automatically run ThrottleStop in the background when the computer starts. All seems to work well: https://valid.x86.fr/ghcmir
