Lenovo X1 Extreme

TSE said:
Blended. No power limits - hitting about 56 Watts. I've done it with the Small FTT - that hits about 91 - 92 degrees, large FFt hits about 91 - 90, and Blended hits 88 - 90. I'd like to see some results from X1e owners to compare.

Primes is not really a good tool to compare, because the blended test mixes large and small FFTs of various sizes for each run and in my case (GS65) there is substantial difference in clock speed between them. And I just realized that if you select large or small FFT tests the passes also are different in it. The small FFT is most consistent, has almost identical parameters between passes.

Also when comparing results, put the fans at max, because otherwise you're comparing fan curves. And don't look at temperatures if you unlocked power limit. It will be always around 90C, that's the throttling point. Although your screenshots show 97C PROCHOT, so I don't really understand why the 90C.

I don't have X1E, but my GS65 holds steady 3.4 GHz in small FFT during the first 3 tests (about 5 minutes for the 12k length tests). 90C throttling limit.

I'm sorry but they are appearing clear to me?

Thanks for the info. I wish there was a way to adjust fan speeds for Dell computers, I haven't been able to find one.​

Ugh .... my new Thinkpad L390Y failed this morning, I suspect it's the motherboard. That's two faulty Thinkpads in the first month of ownership (sluggish X1E, then L390Y turned on this morning and after a few seconds I got a blank screen, keyboard lights went out and fan started screaming - I can't turn it off so I've had a screaming brick sitting next to me for the last few hours. It's too hot and active for me to open up to disconnect the battery). Having now sorted out the sale of my old laptop I don't have a laptop at all now. I ordered Thinkpads because I've always been told they're reliable. Really upset about this - I bought two so I would have contingency if one went wrong!

I heard from a student saying that his brother bought a X1E for gaming. It got so hot that it melted the keys. Is this true?

I heard from someone that there are a lot of tiny Japanese musicians in a Sony Mp3 player, playing all the music. Is this true? LOL :D:Do_O

Edit:
Jokes aside. Hajime, if this really was true wouldn't you think it was spread all out over the news/YouTube/internet?? Of course you can use an X1E for (light) gaming unless it is defective. You shouldn't believe everything you here.

It appears the person is using a different mesh fabric then what is originally provided

Thanks. If I recall correctly, the original provided one is kind of a metal sheet. Did that person say if the mesh fabric he/she uses leads to quieter operations?

No idea, I'm not involved in that discussion. I would read the thread and discern what he meant if that's important to you. Its not important to me as I'm happy with my laptop

I recall somebody bought a X1E with i5 CPU (with a 4K screen?) few weeks ago. How is the performance and battery life?
 
After servicing my X1E, it's a completely different laptop now.
Usually my fans would kick in for no good reason at all, or would always run when connected to my external screens.

Now? If I'm just reading documentation and surfing the web, fans don't kick in at all, and laptop still isn't hot like it used to be. Everything is way better.

They changed my fans, and bottom cover for sure, even though they won't admit that they changed the bottom cover. Why won't they admit it? No idea, and don't even care. I'm just happy that my X1E is miles better to me then it was before. Now I'm waiting for 4K panel, and I really hope that I won't mess up my X1E with another change to it :D

How is your Thinkpad L390Y doing? Any news?
 
Andy, my L390Y has sorted itself out. The whole thing was strange. I had to let the battery run flat as I couldn't switch it off and for the entire duration the fan blared at full volume. After the battery went flat I checked nothing was loose inside, then I plugged the power cord in and switched it on. It recovered like nothing had happened. I am at a loss as to what went wrong and I'm worried this might reoccur, but I can't log a support call with Lenovo because the machine is currently acting normally. When I bought it I did buy an extra warranty for on site support, so I at least won't have to send it in if it malfunctions again.

I'm gearing up to re-order my X1E this week. It's made me realise that as a small business owner two laptops clearly aren't enough in terms of contingency. I'm going to need a third - aaagh!!

Sounds as though maybe a process during initial setup may have hung until it ran down and the OS was able to recover on a restart?
 
I don't know what could have caused it, initially I thought it must be a hardware fault. I'd shut down after doing some work on it the night before, and the next morning it started as normal then as it hit the windows login page suddenly the screen went blank, the lights on the keyboard and by the on/off switch went out, and the fan started blaring. There was no means to turn it off to shut the fan down, it was very strange. As you suggest, it may well have been a process getting messed up on start.

Glad to hear that yours seem to be a different model!


So no more the following? Do you have Nvidia GPU on or off in situations you described above.

1. Alternation between dead silent and noisy or jet engine like fan noise?

2. No more noisy fan even the task list states that the cpu load is 1-5%?

How often do you hear fan noise and jet engine noise? Under what situations?
 
hajime - whatever c0ppo says may not be helpful to your specific case. As stated earlier, your tasks will be different, your processor may have been cut a little differently, your thermal paste may be thicker or thinner, your fans may be from a different batch, your heat sink may be seated differently, other people may or may not undervolt etc etc.

You are never going to get the 'right' answers because there are none, from what we've seen laptops of the same model can all behave differently.

Best thing you can do is re-read this thread fully - including my answers to you regarding my i5 4k version which I have elaborated on greatly (presuming I am the person you were referring to a few posts back).

Hi LindsayD, so undervolt the X1E with i5 could make a quite machine. If I read it correctly, you returned it at the end and tried to get one with i7? How is the different in behavior between the two?

On my Yoga C930, it could handle Office work well but when I tried to test its performance by flipping the image upside-down (a simple task?) using Photoshop, I saw lag in performance. In other tasks, I could see the program processing blocks of images on the screen before the tasks were completed. I don't recall seeing lag on the X1E.
 
hajime, yes it was very quiet fan wise. But I have sensitive hearing and it had a bit of coil whine (probably would not bother many people). It also had a little lag which may have been down to the 4k, but I don't know for sure so I decided to swap the machine and will try an i7. As I mentioned earlier today I'm yet to order my X1E replacement but will try to this week.

I'll test flipping an image in photoshop on my L390 and will report back. What size/resolution image were you flipping - I'll need to know that. The term 'lag' in performance is very subjective.

Thanks. I returned the laptop so the image was deleted. Maybe you can test a 4K image and an image of whatever resolutions commonly used these days?
