2014 Toshiba Portégé Z30-A Haswell with FullHD IPS panel

Alternatively add "processor.ignore_ppc=1" to the cmdline specified in /etc/default/grub - Then run "sudo update-grub" and reboot.
Where did you set "scaling_max_freq"? Startup script or via sysfsutils?

It's what NotebookCheck said it does on Windows, although it is unclear if it solely throttles in combination with GPU load.
I'm just curious if the firmware or the Windows drivers are to blame for that (or a stupid BIOS flag )

Another test would be to stress with concurrent GPU load. This naturally takes away some of the turbo clock, but should not force the CPU to go all the way down to 1GHz like nbc reports - with temperatures being fine!

Doh!
I have no idea where "cpuinfo_max_freq" gets the info from, but your CPU actually goes upto 3GHz. So it should be

Code:

for i in /sys/devices/system/cpu/cpu[0-3]/cpufreq; do echo 3000000 > $i/scaling_max_freq

Keep in mind that 3GHz you only achieve on a single core. When stressing both cores I assume the frequency to go down to 2.7-2.8GHz. (My Ivy Bridge i7 for reference clocks at 2GHz/3.1Ghz(2.9GHz).

There is also the program stress (sudo apt-get install stress). It has several options for cpu/io/ram/hd... so in the long run it saves from writing cryptic one liners

 

Unfortunately that didn't seem to work:

Code:

# for i in /sys/devices/system/cpu/cpu[0-3]/cpufreq; do echo 3000000 > $i/scaling_max_freq; done
# for i in /sys/devices/system/cpu/cpu[0-3]/cpufreq; do cat $i/scaling_max_freq; done
2401000
2401000
2401000
2401000

(and running your test still shows 2.4GHz)

About the throttling: I've run wPrime on Windows for extended periods without throttling, but there are three different energy vs performance modes you choose from in the Control Panel, and I remember from some experimenting that I saw throttling in the energy-saver mode.

 

I guess it won't allow you do do so because it might be limited by the (wrong) value of cpuinfo_max_freq itself.

What happens to cpuinfo_max_freq / scaling_max_freq when you pass both "processor.ignore_ppc=1" and "processor.ignore_tpc=1" at boot time:
- in grub boot menu select the ubuntu installation
- hit "e"
- find the line starting with "linux" and append: "processor.ignore_ppc=1 processor.ignore_tpc=1" (w/o the quotes)
- hit Ctrl+x

What's max frequency on Windows btw?


Also try the newer intel_pstate driver instead of acpi-cpufreq by adding "intel_pstate=enable" to the cmdline in grub (analog to the processor parameters described in tis post)

 

Code:

processor.ignore_ppc=1 processor.ignore_tpc=1

This still shows the same 2401MHz as before.

Code:

intel_pstate=enable

Success!
Running four worker threads shows 2611MHz on all cores, and running one worker thread shows 3000MHz on two of four cores.

In Windows I'm maxing out on 2595MHz with both four and one worker thread. This might be due to peculiarities with wPrime or Hwinfo, I don't know.

 

Sweet!
It has quite intuitive controls by defining your desired min/max scaling frequencies as a % of the absolute max clock through:

Code:

/sys/devices/system/cpu/intel_pstate/max_perf_pct
/sys/devices/system/cpu/intel_pstate/no_turbo
/sys/devices/system/cpu/intel_pstate/min_perf_pct

Keep in mind that the no_turbo flag defines the absolute max clock (for your CPU it should be 1=1.8GHz, 0=3GHz)


What's the temperatures with the new max frequencies? Still no throttling I guess!?

At what temperature does the fan max out? How annoying is it btw? From your earlier output it seems the toshiba driver doesn't provide any control of the fan settings / thresholds.

What does the following say

Code:

find /sys | grep TOS

 

Yes, fan and temps are the same as before and no throttling. It's hard to say exactly what triggers the highest fan speed but my impression is some delay after going above 70 degrees. Then it stabilizes a few degrees above 70.
For shorter bursts of full load the fan doesn't spin up that much but if you plan to run a lot on full load then you will definitely notice But I don't find it worse than any other skinny laptop. Fan-wise the laptop is both good and bad I guess; the fan comes on at low temps (45-50 degrees) but OTOH is fairly quiet at this stage. I'm quite sensitive to fan noise and I would prefer the fan to run less often but I still find it acceptable.

Code:

Interesting conversation !

I will soon do some testing to see if my z30-A-19D¹ has turbo mode enabled (I'm using a Mageia Linux 4 at the moment)...

Another interesting thread about Linux on this beautiful machine is: Toshiba Portege Z30-A-12Q [Linux Laptop Wiki]

¹ I did not find any 17D with an Fr keyboard layout...

 

I just saw that according to toshiba.eu, the 17D doesn't exist anymore and is replaced by the z30-A-1E5 (if someone has some understanding about how Toshiba use numbers for models, I'm very interested because it seems pretty chaotic to me!): Portégé Z30-A-1E5 - Toshiba

 

I expect that the numbering is just chaoting.

Every single customized combination of components gets whatever number there is. And there seem to be a few variations of this product in place. The best approach I have found is to simply ignore anything beyond Z30. It would seem as if Toshiba customize by
* leaving out components (dock, NFC, TPM etc)
* swapping panel while retaining features (FHD panel)
* using different panels and SSDs
* using different keyboard layouts

That should be all the variability there is.

 

Have a Z30-A-19L since a few weeks, the numbering is indeed confusing, can't make any sense of it.

Just a few remarks....the 1920x1080 IPS screen is a joy to look at, am really impressed. Great colors, crystal clear and good viewing angles.
The notebook is fast, silent and in general am really pleased with it. Negative points? Find the keyboard a bit flimsy, and as expected the device came loaded with bloatware. Still, it is easily one of the better notebooks i've owned.

 

Great, enjoy your new laptop!
Sold my Z930 and cannot wait to get the Z30 early October.
This is a great thread guys!

Thank you

 

Thanks!

I tried to install a second SODIMM to increase the memory to 2x8GB but sadly the SODIMM is not recognized, the laptop will not boot...the laptop comes with 8GB Samsung memory, the SODIMM i tried is Corsair Vengeance CMSX16GX3M2A1600C10. I tried all combinations and dimm slots, same result: black screen, pc does not boot.

Compatibility issue i guess, have updated to latest BIOS 3.70 but sadly no luck. The Corsair memory does work when installed in another notebook, so it's not faulty.

Anyone some more thoughts?

 

Hi,
The Z30 takes DDR3L and not DDR3...Is the Corsair you mention DDR3L?

 

OK thanks, completely overlooked this...The Corsair memory is indeed DDR3 1.5V and not DDR3L 1.35V.

:thumbsup:

 

Happy to help. Hope you solve your problem.

 

Has anyone fitted a 2nd SSD in the WWANs M.2 slot? I assume non WWAN models still provide that slot!?

 

Hi to all,
here another owner of this awesome laptop. Mine it's the Z30-A-1DJ i5-4210U/8GB/128GB/13.3" IPS.

 

How did you manage for the warranty? Open the computer will void the warranty, right?

I'm asking because I'm also interested to increase memory...

 

Not sure about this, the laptop is not sealed and installing extra memory is done easily by unscrewing the backplate.

To be honest have no idea if this voids the warranty.

 

Yes I have seen teardown videos of the z30, and It seems pretty easy to open.

Usually the laptops have something (glue, stickers, etc.) to seal one or several screws to void the warranty while the case has been opened.

Maybe the sealing is made with the screw(s?) that are underneath the plastic mat (wich is maybe fixed with some sealing glue ?) ?

 

Hi, I'm a new owner of a fantastic Z30-A-15M.
It's really a great ultra book very light and easy to bring with you.
One minor issue: I tried to change the sad with a new one but I wasn't able to unscrew one of the SSD screw; I tried with different tools but nothing!

 

I also have had the Toshiba Satellite Z30-1e8 for few days. The latest Ubuntu 14.10 installed and works fine but I can't get two-finger scrolling on touchpad working. As the laptop is so light and portable, it would be pity if a mouse is needed for proper usage. As I saw discussion about Linux couple pages before, I wonder how is your experience with touchpad, and if anyone has a solution for scrolling?

 

Hello,

You need to install the newest kernel 3.17 thant support the touch and trackpad of the z30 (and many other features unsupported by previous kernels).

see also: Toshiba Portege Z30-A-12Q [Linux Laptop Wiki]

 

Thanks for the tip, the 3.17 kernel indeed enabled the two-finger scrolling.

 

Hello People,

I am looking for a replacement for my EliteBook 2760p, since it is now seriously more and more falling apart, after years of being a good companion. It is still definitely quick enough for my expectations, just the screen is annoying me to death with its mere 1280x800 resolution.

Since I don't necessarily need a convertible anymore for university-use (done with the languages), I looked for the only 12-14" laptop capable of eating 16GB RAM and having a replaceable SSD & a Full-HD-Screen.

Those are the HP 840G1 and the Toshiba Z30 (xyz, unclear which one to take. I found a comparatively "cheap" PT24CE-00900DGR - could anybody explain me really what that is, since I don't fully trust the online shops in their understanding? Its according to the shop an FHD, matte touch, 4500U i7, 256GB SSD, LTE & 8GB RAM model).

While HP offers a 2.5" SSD (which would theoretically save costs, when they would sell it with i7 & an HDD) - Toshiba goes with a M2/mSATA (?)-SSD. And DDR3L instead of DDR3-NV RAM.

And the Toshiba has the superior battery life while being super light. So I'd prefer that one over the HP.

Does anyone of you have ANY complains (keyboard flimsy, fan-noise, heat issue, display opening angle) and could anyone tell me whether he now (Broadwell is showing up on the horizon) would still go for a Z30?

Thank you very much in advance,
GreenStorm

edit:
Too late product gone. Couldn't afford it right now anyways

 

Hello,

I recently bought Z30-A and have two questions:

a) do your Toshibas start to vibrate slightly when fans reach about 65% of max values?
b) do your touchapads have a "metallic" sound when you tap on them?

Point a) worries me slightly.

Thanks!
Andrzej

 

for me it is:
a) no (no particular vibration, but I don't hear the fans often)
b) no (no sound at all while tapping on it)

The Toshiba warranty is quite good (they say that they repair and... refund !), you should try it !
