2013 Series 7 chronos / Ativ Book 8 15" owner's lounge (NP770Z5E / NP780Z5E / NP870Z5E / NP880Z5E)

Unfortunately I had tried the latest Intel driver in 8.0 after ridding my system of all signs of previous drivers and it exhibited the same disconnect problems as the Samsung provided driver. Perhaps in 8.1 it might be different? I had not tried any other remedies short of praying to Cthulhu to intervene and strike down the Intel engineer responsible for the 6235.

Maybe Byron would be kind enough to investigate possible solutions? j/k

I will check it out tomorrow if nobody else comes up with a solution.

 

Okay, so after a little messing around with afterburner and kombustor today, I've found that my overclocks are sticking. I have the 8770m, running the latest catalyst 13.10 beta, and afterburner beta 14. I still can't move the power slider, but my OC's were stable up to 1000/1300 which is pretty significant. The standard stress test went from 64fps at stock clocks to 76fps with the OC.

Unfortunately when I tried to test a game (I used the Metro 2033 benchmark) the clocks started fluctuating again, and I got no noticeable performance increase. Maybe this has something to do with the kombustor's complete focus on gpu load, whereas an actual game stresses the cpu as well, causing some throttling.

 

Okay after a fresh reboot, I've only done updates. I noticed it did it once, but my PSU was really hot (as usual). I'm thinking it's the windows updates? Are there any unnecessary ones? I might have to take it back for hardware repair.

Thanks again,

Panser

 

Are you saying you did a factory restore, and the problem is NOT there until after you do Windows Updates? Admittedly, some of those updates are bloated (such as .NET) and I wish I could avoid them, but I would be surprised if they cause this kind of touchscreen misbehavior. Other members would have reported it in that case.

So yes, a replacement or repair may be in order.

 

Some of the other remedies described in that thread are important. Particularly the power profile tweaks. I too have disconnects if Wireless Adapter Settings - Power Saving Mode is set to anything slower than Low Power Saving. Default on battery is Maximum power saving which is almost guaranteed to cause disconnects with the Intel 6230/6235.

 

Sorry yes I mean factory restore. I checked the BIOS version, which from command prompt showed me this

American Megatrends Inc. P02ADH.008.130604.SK, 6/4/2013


I saw on the first page that their was a newer version? However, SW Update doesnt show any updates available.


I have the NP880Z5E BTW.


Thank you again,

Panser

 

Others who own this model should be able to better speak to its specific BIOS versions.

But generally, it is better to run the BIOS Updater outside of SW Update, then save the actual BIOS update locally, and run it As Administrator by itself. Safer that way. See John's BIOS Update thread.

 

To bad, maybe I should wait for an updated ativ book then...
Can't find any decent shops that sell them to the netherlands (Really want a Non touch screen version)

 

Amazon DE ships to the netherlands. Keep in mind that it'll be QWERTZ.

 

So I'm having issues with Afterburner and adjusting the clocks. I entered the EULA text and changed unofficialoverclocking to 1 in the cfg file but now when I open up afterburner the sliders are all the way at the bottom and the clock and memory are reporting 0. I'm using the latest afterburner beta version and catalyst 13.8. I also read a forum somewhere by dropping two ati dll's into the afterburner directory but still no luck. Let me know if anyone has another solution or has seen this problem. I have the 8770m as well (np780z5e).

Also does anyone have a OSD program that they use to monitor clock speed while playing a game? Afterburner only allows GPU usage, FPS, and Fan speed for me.

Thanks guys.

 

Have you edited the registry as described in post #1 of this thread?:

 

Thanks pranktank

There was an additional registry entry that I had missed. For anyone else that's wondering change both EnableUlps and EnableUlps_NA to the value 0 and restart. This also now allows me to show clock and memory in OSD. Awesome! Now we just need to figure out how to lock the overclock so it doesn't fluctuate. There's a setting in afterburner called force constant voltage but doesn't work. Possibly need to find an alternative program to force lock the clock speed.

well I can't get switchable graphics/powerplay to work with the new 13.10 drivers. Was anyone able to fix this issue? I tried the suggestion in the first post to no avail.

 

i got 870z5e and also same bios, thats all i got from SW Update, the 7xx and 8xx does'nt share the bios then it seems..

 

Hi guys! I have already complained about my issues with my samsung 870z5e but I did not find any useful respond that could help me with troubleshooting. I have also updated bios to newest version(P02ADH) and I set all settings to default. My problem is that silent mode is not working. As a result computer consumes more energy and it is hottier and loudier. I have already tried to reinstall setting app but without any improvement. Maybe some seetting in bios or I really do not know what can be wrong. Cpu usage is always under 3% but consumption is sometimes reaching 30w. What can be wrong? Any help is much appreciated.

 

Not being overly happy with the first factory backup I have now done another (inc boot stuff) to my 64Gb USB stick. This took about 20 minutes and is around 15Gb so seems about right I guess.

Being the sceptical soul I wanted to check that I could boot to this image but when I go into the BIOS settings I cannot fine any option to boot to anything other than the HDD. Even disabling fast bios doesn't change anything in the boot device menu - it just has an entry for windows boot #1.

Am I doing something wrong? Surely you should be able to boot from USB stick?

Also, once I know the back up is OK, if I select the very first restore (using F4 recovery) will that safely restore to the original "out of the box" system?

Thanks

Rob

 

Yeah I saw that, but will be hard to fix I think. Can't find any posts about replacing keys etc.

 

putting the powerlimit at 120% fixes it on mine.

EDIT: those who have trouble changing the power limit, check, on 13.10b drivers if you can change it in ccc. It's under performance>overdrive.

 

Which 13.10b did u install? The one officially from AMD website or the LeekM powerXpress enduro fix drivers that includes the intel and APU drivers seperate?


Sent from my iPhone using Tapatalk - now Free

 

the official 13.10b drivers, I then used machater's app

 

Are you referring to these drivers? AMD Catalyst If so, I do have this version installed and I don't see overdrive under my performance tab. I don't know what app of MacHater's your referring to? Two Finger scroll lol?

 

Would it be a mistake to change the np770z5e to 870z5e ? The only difference i see right now is the black body and the maximum use of RAM (16GB)

For me it is sometimes hard to recognize the letters when backlit is on. Silver body and white backlit is not the best choose....
I use the chronos most time on my sofa, so my viewing angle differs as compared with sitting at a desk where i can recognize every letter with backlit on.

 

Yes official 13.10b, LeekM's fix may be the reason I have it and you don't indeed. Haha no this one, which installs LeekM's fix: http://forum.notebookreview.com/sag...7800-7900-8500-8600-8700-8800-8900m-gpus.html

 

I am wondering which setting in bios is responsible for increased power consumption because after setting all values in bios to default samsung laptop consumes slightly more energy(15w and more compared to 10w that consumed before). As a result battery life is poor and laptop is noisy. Please help me to solve it. Thanks in advance.

 

Although the factory image itself could be just around 15GB, I would expect the total backup to be larger. Are you sure you enabled the Create Boot Disk option when you made the backup? Again, the procedure is described in this Samsung guide.

As for booting the USB, I would disable SecureBoot and set OS Mode Selection=UEFI and CSM OS (in addition to disabling Fast BIOS). But some members here have reported they didn't even need to do that. In any case can you set these back after the restore.

After you saved the correct BIOS settings, you need to either (A) go back into BIOS and select Boot Priority, or (B) press F10 at boot (Esc on some models) to select boot device.

And yes, you can F4 boot Recovery and restore to factory. You can do that any time (before or after the backup), it should not affect the contents of your backup, since you are backing up the factory image.

Hope that helps.

 

just curious how many of you use intellimemory. i uninstalled it, but wondering if it might be beneficial as samsung claims. whats the consensus about that?

 

did you try eco mode in quick settings?

 

Hi folks - I posted this in another thread but figured it might be of assistance in the owner's lounge for those who are MSDN or Technet subscribers with legit versions of the 8.1 ISO. That particular ISO permits the install of both Pro and Core versions of Windows 8.1 but no need to waste the key generated by MSDN and Technet when you can use the OEM key that came with your notebook. These instructions worked for me - in the absence of updating the video drivers to the old 8.0 drivers from SW Update, you will get a black screen on your first reboot after what appears to be a successful install of 8.1 (thanks Byron for the tip). So here goes:

1. To prepare for the install, download the Intel display drivers and AMD drivers via SW Update (export) and save them to an external drive or your desktop. Also download the Settings app for the Samsung NP940xxx.

2. Create a file called ei.cfg with the following contents:

[EditionID]
Core
[Channel]
Retail
[VL]
0

Save and place it in the Sources folder of the install iso.

2. Install 8.1 and you will not be badgered about a key - make sure you have your previous CD key (use keyfinder - aka magic jellybean keyfinder to get it).

3. After successfully installed, DON'T REBOOT FOR ANY REASON. First install the intel drivers and accept that you are installing an older driver. DON'T reboot. Then install the AMD drivers. DON'T reboot. Finally, uninstall the version of Settings you have and then install the Settings app that you downloaded for the NP940xxx.

4. Now you can reboot.

5. Tweak the wifi settings as per the wifi remedies thread.

6. You will need to reinstall the bluetooth drivers as well as be prompted to update the wifi drivers. Once again, if you do, use the tips in the wifi remedies thread. Also, you will be prompted by the notification that the WIDI drivers need to be reinstalled. If you care about WIDI, you can do so.

Enjoy!

 

I have already tried using eco mode but it did nit help. Even with silent mode and eco mode enabled I am anuable to get less than 16W. However, ntoskrnl permanenly eats 7% of my cpu. Before samsung laptop consumed only 8W and now it is much more.

 

I'm running amd drivers 13.10 beta b and I downloaded MacHater's fix. Still no power limit adjustments available in afterburner. My gpu usage % still fluctuates, my core clock jumps around from 650 to 775 despite stock clocks being 825 and being overclocked to 950, and memory clock still runs at stock/1125mhz despite being overclocked to 1200hz. Max temp reached while playing metro 2033 was 70c. I am running Metro 2033 at 1920x1080 at preset High with a avg fps around 28.

 

I wonder if the switchable graphics isn't working and it's always using the AMD GPU.

Which GPU is listed by HWiNFO?

John

 

Laptop is using intel gpu all the time while running on battery. However, I have noticed that only slight cpu load(4-7%) significantly increases power consumption. Silent mode is on as well as eco mode. I assume that it is all because of cpu is not throttling as it should in silent mode. I just do not know how to solve this issue. May it be related to some bios setting? Thanks for help.

 

Did you check if there's an overdrive under the performance tab in catalyst control center like pranktank suggested? If so try setting the power limit there.

I don't even have a performance tab.


Edit: Did some quick research on how to enable the performance tab with overdrive and I found this https://docs.google.com/file/d/0Bwd...S00NjU4LTk2N2ItYTUwZTFlNWY3Mjcw/edit?hl=en_US Unfortunately, I can not save my vbios because trixx gives me an error "could not acquire bios" not only that but I also don't have the folder "Overdrive2" in my registry either. Sigh.

 

Either Silent mode or Eco mode should lock the CPU down to minimum speed. Check the CPU speed display in HWiNFO.

John

 

All cpu cores are set to 1998 MHz so silent mode is working. I have no idea what can be wrong.

 

Hi again! Today I downloaded CPU-Z and Speccy by Piriform to simply check up on the computer and noticed something weird. Both softwares say that the RAM modules run at 799 MHz even though it should be running at 1600MHz. This is the model of the laptop: Samsung 880Z5E-X01SE. Things that may have caused this is that I cloned the HDD and swapped it with an SSD, otherwise I have no idea what may be causing this. What do you guys think?

 

Something is not working correctly: The CPU should be running at 800Mhz and speed up when there is work to be done. That explains the high power consumption.

How to get it working correctly is the next challenge. Start by disabling Silent Mode and Eco Mode and making sure that the Samsung Optimized power plan is selected. Then reinstall (Easy)Settings. Also check that SpeedStep (or whatever it is called these days) is enabled in the BIOS?

John

 

I would make sure the Power Saver profile is selected when you activate Silent/Eco Mode. And check the settings in that profile.

Silent and Eco Mode both work on two fronts:

1) They cap the CPU to minimum speed. This is accomplished through firmware. Other than uninstalling/re-installing Settings (to enable Fn-F11 and the Silent Mode and Eco Mode tabs in Settings) there is nothing you or any software can do to interfere with this function.

2) They switch to the Power Saver profile, which has different System Cooling Policy (controlling fan operation) and other power management settings, compared to the default profile ( Samsung Optimized or Balanced, depending on Settings version). The user can modify this profile (or switch away from it after toggling on Silent/Eco Mode) which will affect how Silent/Eco Mode behaves.

There is more detail in this post and the ones following.

If the Power Saver profile is messed up, I am not even sure uninstalling/re-installing Settings will fix it -- although I haven't tried it. The POWERCFG command is how you can manage power profiles (export, import etc) but I don't think there is a way to reset corrupted power profiles to defaults (if indeed that's what happened on your PC).

Edit: Silly me, I just remembered Windows has a function to reset power profiles to default (see below). First follow John's advice to check that Silent mode even works (CPU speed is capped). This was only if you have fan or other misbehavior when in Silent/Eco Mode, which could be explained by a messed up Power Saver profile.

 

The ram is running at 1600Mhz.

in programas like cpu-z and speccy you have to times your ram frequency by two to get the actual speed. It is taking into account the multiplier, so it only shows it as half.

 

It's because it's DDR ram. DDR = Double Data Rate, so 800mhz = 1600 mhz.

 

Aah! All right xD I was getting a little worried there Thanks for explaining this to me

 

Ok - on Windows 8.1 and things are kind of working ok but iTunes won't start. Interestingly it starts no problem on my MS Surface Pro with 8.1 installed. In researching the issue, it appears that the Intel display drivers could be preventing it from loading (believe it or not) but I had to install both the release Catalyst drivers and stock Intel 4000 drivers to get graphics switching working properly so that I wouldn't get a black screen in 8.1. If I update to official Intel 4000 drivers now, and then reinstall the stock Catalyst drivers that contain the graphics switching utility, is that likely to screw things up again? Wanted some educated guesses before I took the jump (or experience from those of you who may have tried updating to newer non-Samsung provided 4000 drivers). Thanks!

 

Believe if you update to the official intel drivers it disables switching. Doesn't hurt just trying but pretty sure.

 

Yeah you could try the ones from the ativ book 9, they are the latest ones, if they don't install the ones from intel do disable switching.

 

Well i'll wait until either (a) Apple releases iTunes 11.1 and/or (b) Samsung updates the drivers for 8.1. Thanks folks,

 

at least wait until 8.1 is actually released, im hoping and assuming samsung will release drivers at or around launch. is it really worth the hassle when 8.1 comes out in a month? Whats the advantage?

 

Yep - I agree.

 

hello everyone on this thread. I just picked up a new Series 7 Chronos (touchscreen one). Maybe someone here might be able to tell me which model I have. It says it has 16 GB of on board RAM out of the box but I can't seem to find a model online with that. Anyone know why?

 

Isn't there a label printed on the bottom with a model number?
