well, ur cpu might still be downclocking due to speedstep. if theres a stutter caused by the system drive, it might make the cpu think "oh, nothing to do! alright, lets chillax then..."

 

Ah...i thought you already updated your bios also since someone gave you that advice a few pages ago.

Ok so now I'm anxiously waiting your result as I was planning to buy the MX100 but will go with the 850evo if that's the reason for your probs aswell.


Later edit: It would be interestimg to see if throttlestop fixes both the throttling AND the freezes.

Throttlestop might very well stop the cpu clocking down but if you still have some stutter/freezes after that , even if your cpu is rock stable then that might mean that it's still the drive

 

I was under the impression that a 1080p screen uses a different cable than a 4k screen so installation won't be a straight forward swap.

If you plan do this, just research it.

 

Where is the delete button

 

I came in late to the possible MX100 stuttering issues. Is there a good method to test for this assuming I get the CPU to stop throttling?

 

Is the crucial the only drive in your system?

The best way would be to install win and game on a different drive if you have the time.

If upgrading bios/EC does not fix it direectly, personally i would do that before using throttlestop just to rule out any drive issues.

Otherwise i am not aware of any method to test if the ssd is ok.

You should still see some visual stuttering I guess..

 

Ok. It is the only drive. I'll see what I can determine. I gotta get started on these taxes first...

 

Why do you try to run CPU at 3.5 GHz? I locked it to 2.9 GHz through ThrottleStop and it doesn't exceed 80 celcius. I really can't notice any difference in games.

 

It worked before I took it apart. The problem is intermittent as I had taken the chip out a multitude of times. Remember that the wifi portion works at all times. Just waiting for new one.

It doesnt look like the chip was damaged either.

 

It's just so weird. that the symptoms with bluetooth are identical for almost all 1525AC owners...

Cakefish, omer.sak, you...and atleast one other guy whose name i can't quite remember.

Might there be a defective first batch of cards?

 

Why would he intentionally limit his CPU like that.

The man clearly stated that CPU doesn't overheat.

Even if it did, overheat you'd be better off undervolting it by 50-60 mV and only after that limiting the turbo.

I believe with an undervolt the cpu can hold 3.2/3.3 Ghz turbo without any problems and without overheating

His problem I think is either due to BIOS/EC or just a defective SSD

 

I'm not *trying* to run it at 3.5. I've left everything the way it came from Mythlogic, only messed around a bit with the Hotkey/Windows power plans since discovering this throttling issue. In games the CPU temp has yet to crack 80C, and is usually in the upper 60s.

At any rate, I've discovered I don't have all the paperwork yet to do my taxes, which means I can start finally troubleshooting this. Since I got my PC from Mythlogic, I decided to try to get a BIOS from them first. They aren't being very easy to work with. They asked me why I want a BIOS, so I said it was to troubleshoot CPU throttling in Star Citizen. They said they don't support Star Citizen. I said of course you don't, do you have a BIOS or not, and they said they would escalate my ticket. Feels more like working with Dell than a boutique vendor. It's happening in Planetside 2 as well, so I told them that too, but at any rate I'm ready to just use the XMG one. If anyone would like to link a guide to update the BIOS, feel free, as I haven't done this in a while. In the mean time, I'm going to try to figure it out on my own anyway. I think Prema's site has a guide on it.

Edit: Found the guides on Prema's site, plus the service manual which has the instructions in it. Is there a way I can make a backup of the current BIOS, in case I have to send it back or something?

 

Prema has a stock bios also on his website so you don't need to save a backup. When you want to send it back just fownload and flash the stock one.

I suggest you use prema's bios instead of XMG

XMG Bios will give you their logo on startup and is stock other than that

Mythlogic has a rep here on NBR so you can try PM'ing him.

P.S. what service manual are you talking about?

 

Just received my P650SE on Wednesday - it runs great! Any game that I play runs beautifully.

However, I've run into a problem that started happening last night (hopefully I can post this here).

My CPU idles around 38c-45c, and with chrome open, around 50c. When I open up a live-stream on Twitch or play a YouTube video, my CPU temps increase sharply to around 70c. The CPU temps only rise when I am viewing the tab with Twitch/YouTube. If I have the stream/video running in another tab while viewing a separate tab, the temps start to idle out and go back to 40c-50c. I'm not really sure what to do at this point.

 

well i guess thats ur igpu being stressed while streaming high quality content?

 

This is my goal (currently not enough power to OC CPU and GPU like that under heavy load):

Spoiler

 

Testing I did just now using YouTube:



CPU and GPU loads were observed using Task Manager and GPU-Z, respectively. Firefox failed testing as the highest setting you could select in the browser was 720p/30fps (it has major issues with Google's HTML5 video engine, which recently became the mandatory player on YouTube, replacing Adobe Flash).

In conclusion, Chrome's hardware GPU acceleration is rubbish and seriously needs improving.

 

look at that, who wouldve thought IE to be the best browser in ANYthing, let alone ressources and performance? nice write up cakefish, kudos

 

I think Mythlogic's bios is also stock but with their logo. Prema's stock for the SG is 1.03.03. Mine came with 1.03.04 and XMG has 1.03.05

The service manual found here: (I've seen it a couple other places since)

https://biosmods.wordpress.com/service-manuals/

 

Yea I have also noticed the fan ramping up to high speed while watching Twitch in Chrome, I will give Firefox a try tonight.

 

Thank you for doing those tests. My playback is smooth in chrome and there are no frame spikes that I can visually see (Although my temps are still pretty high). This wasn't an issue for me the past couple days while watching a Twitch stream - it just started happening last night.

 

So that means your bios is up to date.

I mean 1.03.05 is newer but 1.03.04 is stable ...it's the one prema uses.

What version EC do you have?

EC 1.03.04 is the one that prema provides for Bios 1.03.04

 

...like the OP of this thread, for example?

 

I have also noticed that Internet Explorer 11 offers considerably smoother scrolling than Chrome, in all webpages, even in these forums. Chrome really needs up its game - get to work Google! Else Spartan will win me over once Windows 10 arrives. I am tempted to switch to IE11, because of the much smoother browsing experience, however, I much prefer Chrome's UI, navigation menus and bookmark syncing. That's why Spartan could be the ultimate browser for me - if it keeps IE11's great GPU acceleration and adopts a more Chrome-like UI then I'm sold.

 

I've noticed that while plugged in, my CPU temps are ~70c when viewing a Twitch stream. When I unplug the power supply and run on battery in "Maximum Battery Life" mode in Intel HD Graphics control panel, the CPU temps drop back down to ~50c (while watching Twitch stream).

 

I had EC 1.03.03. I flashed EC 1.03.04 from the mySN site. I tried that first without flashing over my Mythlogic Bios, but I couldn't boot into Windows as it said I had no system drive. I tried loading the defaults and it didn't seem to work. I went ahead and flashed the XMG 1.03.05 bios and then it worked fine. I'm not sure I had to do that; after flashing the bios I had to have it in UEFI to boot to Windows, which I didn't think I had to do before. I was kind of in a panic mode when it didn't boot from my SSD.

At any rate, I'm now running EC 1.03.04 and bios 1.03.05 both from the mySN site. The stuttering is gone. I randomly went to page 150 and it was exactly where Cakefish was having the same problem on Christmas Eve, so I read up on that, and sure enough the same fix worked for me. Oh, I also updated the Clevo hotkey/fan software as recommended. I think it was Wickette who had the winning recommendation in both our cases.

Here is XTU in a 30-min dogfighting session in Star Citizen:

The CPU actually got quite hot, I think I saw 98 once or twice. I'm on "entertainment" in the Clevo program which is the new default I guess. I have a radiator in the room and the laptop doesn't have the best ventilation. If I put the fans on max it might help a little more.

I do have one new odd thing now. Before when I had MSI Afterburner on, the dGPU would be "on" continuously. Now, it activates and deactivates every other second. It's not a huge deal as I only run Afterburner when I want to see temps/frames/etc., but still maybe there's a setting that got changed?

 

You can try to undervolt CPU using XTU.
Try it with - 50mV first and stress test to see if it's stable (but at -50 I have no doubts that it's ok). You can continue to lower it by 5 mV and do a stress test everytime.

Stick with the one that is stable.

The temps should go down.

If that's not enough just lock the turbo @3.2 Ghz and your CPU will most definetly be chillin' )

Dunno what to say about afterburner

 

-50mv seems to keep it mid-80s in the stress test. I'll stick with that for a bit. Thanks!

Just glad the stuttering is gone!

 

Cakefish the HTML5 YouTube player isn't mandatory, but it is now the default.

If you use YouTube Center you can force YouTube to use Adobe Flash in most browsers.

Will be interesting to see comparisons to HTML5.

 

I also noticed slow rendering on Chrome with 4K. for example, if you open a long website like www.engadget.com and try to scroll fast all the way to the bottom, you will notice the tiles being slowly rendered. I tried, IE, Firefox, Opera and Chrome. Surprisingly, IE was the smoother of all, scrolling fast and without slow tile rendering,

Firefox and Opera were faster than chrome but not smooth like IE.

I was able to improve the rendering speed on Chrome with 4K but still not as good as IE. to improve it you need to ensure that the GPU Rasterization is forced for all pages, enable is not enough.

Check if you have hardware acceleration and multi-thread for rasterization:
1. Type on the address bar "chrome://gpu"
if you see the following, then you are not accelerating rasterization.


To activate it:
1. Type on the address bar: chrome://flags
2. Search for "Enable GPU rasterization" and select "Force Enabled for all layers", enabled is not enough it has to be forced.
2. If multi-thread rasterization is not yet active on yours, search for "Number of raster threads" and specify how many threads do you want to use for rasterization.
After activation, the chrome://gpu should look like this:



This helped a little to smooth the scrolling to match Opera, and Firefox, but IE still smoother. At lest this was my case.

 

Laptop is back and gaming is completely stutter free! I wouldn't have guessed the SSD was causing the stuttering myself so I am glad that Prostar was able to isolate the issue. I have a Crucial MX100 in my desktop rig and it runs flawlessly, I guess this one was just bad luck of the draw.

Has anyone tried the Chromium Wheel Smooth Scroll extension for Google Chrome? It feels a lot better than the default scrolling behavior in Google Chrome.

 

I'm also experiencing throttling on and off while playing Shadow Warrior. The XTU benchmark utility is showing 0% thermal throttling (although CPU utilisation fluctuates regularly); running the Unigine Heaven benchmark on Ultra produces throttling on occasion. Looking at data from NVIDIA Inspector, the throttling (periods of reduced GPU usage) seems to have nothing to do with the dips in voltage and clock speed. As far as I'm aware, I don't have the M100 installed; Mythlogic used two 256GB Samsung PM851 drives instead. Any idea what's happening?

 

Can someone remember what was the default number of posts per page on the previous forum interface?

I have a list of bookmarks/pages where various fixes for various problems where found in the old forum but they aren't working anymore, so I'm trying to translate where those pages would be in the new forum interface.


Later Edit: Also can someone that has Prema's Bios installed tell me if you have acces to vCore voltage and multipliers from BIOS?

I want to undervolt and change the max Turbo Boost for my CPU without using any software when I get my laptop and was curious if Prema's Bios will allow this

 

Hey guys - I want to buy the 17 version but this thread is much more active. I had a question about the HDD config (I'm not very good with that so if I'm getting confused let me know). I undersstand there are one bay + 2 m2 slots of which 1 PCIE correct? I wanted a 1TB hd + 2*256 Raid 0 SSD. Is that possible, or do I have to go with 1tb + 1 512 PICE SSD? If both are possible, which would be the fastest?

Thanks.

 

I use it all the time now. On both the lappy and the desktop. I was getting quite fed up with the jumpy scrolling before.

On another note, anyone else tried the mobile G-Sync drivers with this laptop yet? I'm downloading on potato internet so I'll be testing later today.

 

I don't think G-Sync works on an Optimus.

As a word of warning, the AC 1525 replacement I got did not work for Bluetooth...

The Bluetooth portion of the adapter disappeared completely. Might have to suck it up and use the Intel 7265AC if I want BT functionality. Otherwise, it works great without it. Only borrowed a mouse anyway.

 

did you have to mod the inf?

 

@Cakefish

it looks like you are the only one in this forum not having issues with it. My issue is the disappearance of the Bluetooth without warning: i use it with my Bluetooth mouse, and sometimes it just disappears, then shows up at the next boot, it is a bit random.

From what I read, could you tell me what driver version are you on? For Bluetooth, and wifi + killer suite if any. And I think it is important, in what order did you install them?

Thanks mate, your help will be greatly appreciated in this!

 

Looks like HTWingnut also has the same prob with bluetooth on both his P650 AND P750

@jeanandjackstyle this clearly has nothing to do with drivers.

If the bluetooth isn't detected in device manager, drivers won't do didly-squat

 

So... the intel card goes back to being my recommendation now? Yes? Good to know.

 

Well I wouldn't go so far as to say that.

If you need bluetooth then yes...killer seems to be a no-no.

If you want rock stable wi-fi (more important for me) and don't care about bluetooth then by all means go with 1525.

Who knows, qualcomm might actually fix this in the future and we can get the cards swapped ,since laptop retailers like Schenker/XMG have acknowledged the issue and are refusing to use this card anymore and have alerted them to the issue.

If the guys @ gentech, xotic and all the other retailers with a presence here on the forum who read this would do the same(as in send qualcomm a message) it will probably be fixed sooner rather than later.

I'm curious though how this card works in other laptops than clevos as I have a feeling that the actual M.2 slot that clevo is using might be the one that isn't compatible with these cards since I haven't heard anyone in MSI and Alienware forums complain about this.

Also could the guys using this card tell me how is the range?

Notebookcheck reports it being rather mediocre in the MSI GT72 and acceptable in the Alienware 13

 

is there any way i to measure my wifi, just to make sure that
my 7265 is working like it should?

on my daily work, i didnt notice any problems with that card, since i installed the
newest drivers. but somewhere i read something of micro-stutters, or high ping rates?

My actual wifi driver version: 17.13.11.5

 

Go to command prompt and type: ping google.com -n 500

That will ping google.com 500 times. In the time column you can see the ping. The 7265 has an issue where once in a while ping jumps to 5-600 ms so check for that.

 

Nope. I'm just a goose. Won't work with Optimus. Should've known.

 

My ping oscillates between 2 and 13ms with my 7265, the high ping dirac (impulsion) is non-existent for me, only on my past 7260.

properly configurate the intel 7265 using the gs60 thread, don't install wifi manager softwares (intel wifi software for example) only the latest driver.

 

That's an ironic twist of fate, seeing how I was the very first to have this problem in these forums!

I have the following:

Qualcomm Atheros Killer Performance Suite 1.1.48.1376
Qualcomm Atheros 61x4 Bluetooth Suite (64) 3.0.0.400

I honestly can't remember which way round I installed them. I didn't actually even bother to uninstall and reinstall the drivers when I swapped the original card for the replacement one - it was literally just plug and play!

I hope you and the others can get yours behaving properly.

 

Regarding the n1525, here's a timeline of how the bluetooth of mine started working without replacement:

1. Out of the box, Bluetooth didn't exist - nothing in the device manager
2. Installed latest drivers as mentioned in N1525 thread - Bluetooth still didn't work
3. Opened up laptop, replaced wires in card several times - Bluetooth still didn't work
4. Updated my BIOS with PremaMod - Bluetooth Appears for the first time and works perfectly - but vanishes again at next boot
5. Uninstalled and Re-installed latest drivers as mentioned in N1525 thread - Bluetooth still didn't work
6. Opened up laptop, removed wires, took out screw and card, placed it in again firmly, taped down wires firmly - Bluetooth was spontaneously back and has been working perfectly to date, for around 10 days now (touch wood!)

After all that, I honestly still can't pin-point what the problem was, and why it then became perfect.

 

A first detailed SM951 review with a comparison to the samsung XP941 is available here:
http://www.tweaktown.com/reviews/6951/samsung-sm951-512gb-2-pcie-ssd-review/index.html

 

Well...to me it's actually crystal clear....

As I said before the pins on the card are probably not 100% aligned with the ones on the m.2 slot.

Even a tenth of a mm can make or break the connection. I honestly think you got lucky and just placed the card in the perfect position in wich all pins make proper contact

 

I am assuming it has to do with the fact that it doesn't take the full M.2 slot for the wifi+BT.

EDIT: Did a thermal test for fun over the weekend. 5 Hours of BF4 on Ultra preset @ 1080P had exactly no throttling while running at 3.39GHz using Balanced Power Settings. Temperatures maxed out at 74C for CPU and 72C for GPU. Not sure what made it any different.

EDIT2: Forums are still wonky for my phone. Apparently 10 messages spontaneously appeared since I saw the last post in quote...
