Any Thinkpad P52 owner?

And the new P1 or X1 Extreme might also have great discount at that time. It might not be 40% off, but I believe at least 33% off.

 

Order cancelled. Thanks for the advice!

Neither Dell or HP seemed to even come close to touching the value of the P52 even with only 25% off... But I’m all for saving more...

I had not seen this review on the P52 yet.

With i7-8850H + Quadro P3200 6GB, they include some benchmarks as well with i7 vs. xeon.

Hello

i receive on monday a P52
8850H
P3200
FHD
win 10

I have some problem with the temp


I made measurement with a XTU
in idle mode i can reach 70°C
In stress test its 95°C and more during 5 minutes

I have doubt because lot of people arg that P52 with 6 core can reach 95°C easily

if anyone can tell me what is the "normal" temperature thanks

 

not normal, you have to repaste yourself or schedule a service with technician

say the high temp is causing thermal shutdowns / sudden shutdowns during work

 

thank you for this conceil

I called the technical service. It's very weird. he explains that it never happened
He agrees to change the processor and the cooling system
But there is 3 weeks of delay

In the meantime I do not use my pc to avoid damaging it even more
can peaks of 100 ° C damage other components?


another weird chopse: the max CPU frequency is constantly changing

 

If it's 3 weeks then I'd rather just return it.

 

from what they told me
Lenovo does not replace
He proposes either to repay it and to buy it back
or repair it

Normally for a new product PRO I should not have as much delay to see a technician

I managed to contact a technical manager in France to find a solution

The problem is that for the refund the delay is 14 days and Monday it will be 14 days that I received my laptop

 

If you return it now wouldn't lenovo be obliged to give you your money back regardless?


Return policy in the EU is 30 days(?) and the customer can't be charged return fees and/or restocking fees. If they're deliberately trying to stall your refund then just contact the consumer protection agency immediately.

 

the price was negotiated for a bulk order
If I return the laptop he will refund me but I could not have this price if I want to buy another one

I have to discuss this tomorrow with them

But their after sales service is really horrible, For the moment They do not answer emails and it is very difficult to have them on the phone

 

Contact the consumer protection agency to put pressure on them?

 

No, at least in Sweden it is only 14 days unless the seller decides to up that themselves. Have not heard about Lenovo doing it, at least not here (we are still forced to shop through Digital River)

weird, I thought you're covered under EU?

 

Yes, that's why I don't think there is a general 30 days return window

My P52 ordered 9/22 is scheduled to ship this Friday 10/5! Sweet!

Edit: Shipped and has a tentative ETA of 10/11.

 

Out of the box i7-8850H puts up an 1185 Cinebench R15 on the first run.

P3200 Open GL Max was 152 FPS.

Did a quick Prime95 torture test for 5 mins or so and HWinfo reported CPU temps jumping immediately into the high 90c’s and settling in the low to mid 80c’s with a sustained cpu speed around 3.2mhz on all 6 cores.

The fan does seem to delay its ramp up, which can’t be helping things.

Haven’t had much more time to tinker with her yet though.

the issue with dual fan thinkpads, not possible to control the fans yet


you can disengage one fan, but the other will just completely stop spinning or ignore the disengaged mode at all



tpfc accesses EC, while thinkfan on linux communicated with thinkpad-acpi iirc

 

Should I expect any issues with my 4 RAM modules if they were sent the following way?

Row 0 = SK Hynix
Row 1 = Samsung
Row 2 = Samsung
Row 3 = Samsung

All the specs in hwinfo seem to match up. Just want to make sure.

 

I'm thinking about purchasing the exact same configuration: i7-8850H / P3200.
Have you had a chance to further test the thermals?
Are you satisfied with the laptop?

 

I haven't really gone to test the thermals much further. If there is anything you'd like me to run, let me know and I'd be happy to help.

I have not tried or investigated much about undervolting either at this point.

Other than getting a little warm, this laptop seems like a beast. Granted I'm coming from a core i5 and MX940, so many could seem easily better!

What are your main uses for it?

 

Programming.
I build (mostly maven), and compile very large applications.
A few VM's etc.
So I'm mostly concerned about cpu loads as I won't be utilising the GPU that much (occasional gaming).

Ok, I wish I could talk more to that, but it is way out of my area of expertise. All I would say is probably don't worry about upgrading to the P3200 in that case?

 

I don't game often, but when I do I want a smooth experience

Well there you go! I'm not going to stop you. lol

Looking at what some folks have done by undervolting the X1E, it seems to have provided better results as far as the CPU goes.

 

Back to your thermal question. Using Intel XTU, I have now undervolted her -.165mv and do not hit thermal throttling on the Prime95 "blend" torture test.
Cinebench R15 high score is 1293 now and consistently in the 1250 range.

Only throttling I'm getting is power limit throttling. With XTU, I've turned up the turbo boost power maxes to "unlimited" and still hit the power limit after around 1 minute of the blended Prime95 test. I just don't think she's able to get enough juice.

 

are you sure you're not hitting 90c on the core or package?

from my experience with the P71 and X1C6, the EC will reset the power limits once you cross a certain temperature threshold

 

Hmm. That is possible. Here is my HWinfo screen shot from the 10 minute R15 loop. Maybe I misunderstood, but it throttles when over 90c?




Sent from my iPhone using Tapatalk

 

Yes, it's entirely possible that the 90c is causing the TDP to be reset. As I have said before, this is the same behavior as in the P71 and X1C6.

 

Ok I will have to run some more tests and see if getting above 90c seems to be the trigger point. Thank you!

You already repaste or still using the machine as is?

 

Still just using as is to see how good the stock paste is/was.


Sent from my iPhone using Tapatalk

 

The stock paste is worthless, don't waste your time.

 

This screen shot I took in XTU with the redline on the graph indicating package TDP. This seems to bounce up and down similar with the Package temps. I imagine this is what you are referring to? The first downward blip happens right in sequence with the temp hitting 90c. Then the cycle begins again and again. So, no way to fix this without re-pasting it looks like.

 

Once it crosses the critical temp mark it'll stay on default TDP 45long/55short or even lower than that until you take the load off the CPU and let it cool (reapplying higher power profile after safety trip doesn't work)

Where are you located? Does Lenovo provide onsite support to your area? Because I don't trust the depot repair at all.

 

I'm in the US, but I only ordered with depot. I'm also still in the return window. But chances are I end up with the same issue if I just returned it.

 

Oh

You didn't buy the onsite warranty upgrade? It costs less than 15US$ for 1 year depot to 1 year onsite (perks website, PM me for code). Or did you get one of those overpriced retail "topseller" model with 3 year depot standard?

 

I did use perks. But for some reason I remember the on-site being more than that. Can I still upgrade post purchase?

Well, I just returned my P52. Not really anything wrong with it besides being a bit to heavy and bulky for my needs and once you get used to something more compact, the adjustment was harder than I expected. But nothing wrong witht the laptop as such, in many regards much better thant the XPS15 I now have again.

 

You can still upgrade post purchase.

I'm not sure if you can actually use perks pricing to upgrade the warranty post purchase, but the discount between perks and normal isn't that much on the warranty department.

Try calling sales and see if they can upgrade using perks or direct you to the perks aftersales department.

Did you return the item already or in the process?

I might consider buying it depending on the specs.

 

Already returned. Also guessing that you might not be based in Sweden but a really nice laptop if it is the right fit

Anyone with their P52 notice the keyboard seems to lag on the first couple keystrokes after not typing for awhile? Enough that you think you didn’t press the key enough to you press again and get double stroke and have to backspace and redo. I also notice this with sound prompts that pop up and seem to delay from when you’d normally hear them.

Anyone get the firmware update that pushed through over the weekend?
I'm on N2CET31W 1.14 now

 

How does the bios compare to the older one? Do you notice more throttling or more power limitation?


I'm considering to get a P52 once the discount hits 33% or higher again. Perks is stuck at 27% for a while now.



Edit: quick question for FHD owners. What exact panel do you have?

Run moninfo ( https://www.entechtaiwan.com/util/moninfo.shtm) to give you the exact panel make/model.

 

I don't notice a lot of change so far. Biggest test has been rendering a 4 min 2160p 60fps video in DaVinci Resolve with color correction and some transitions. It rendered that for "youtube 2160p format" in 16m30s.

HWinfo reports thermal throttle on only cores 0 and 2 after a couple mins and then core 4 after about 6 minutes, but not constant.
After 10 mins, the lowest core avg is 78c and highest is 88c.
However, power limit throttle hits quickly on all 6 cores.
Average clock speed around 3.2 Ghz
Average CPU package power at about 42w
I wish Resolve used more GPU as it is only using about 13% capacity

UHD screen here, so can't comment on that.

 

Was cpu overheating before?

 

There seems to be a pattern that it will thermal throttle when a process starts but once the fans are up to full speed I don’t get thermal throttle before. I don’t believe that has changed. Honestly not sure what did change in the BIOS update.

Then you really need to repaste to remove the overheating equation out of the way.

Try this tpfancontrol fork that works with dual fan thinkpads to disengage the fan: https://github.com/Blinky42/TPFanControl

 

I’ll have to check it out. Thank you for the link. Also plan on repasting, just need to do some research first.

Use "manual" and put in speed "64"

It will be faster than what normal fanspeed is able to achieve.
