Win 8.1 High Load Crash (Solved)

Recommended Posts

¡¡¡SOLVED!!!!

***GTX 960 working Drivers 353.06***

 

Hey guys, my eGPU was working like a charm, about 3 days ago I experienced several random crashes while playing, while doing the kombustor test, rendering, etc... The errors i get would be the following:

-Display bios stopped working and recover error

-nvlddmkm error

-Black screen

-Frozen screen

-And quite a few others.

 

Tried trouble shooting it without any luck, but the only common factor i found in every single crash was the following. According to the afterburner my GPU's power skyrockets to something that is plain stupid in about 20-30 secs of heavy work. Here is an Image for you to better understand it:

12751790_10156335214370538_48460084_o.th

 

The image sucks, but at leasat you can tell that the power % goes over the 150 limit. If any1 got a fix would be awesome. I already reinstalled win 8.1, but no luck at all.

Funny story, it works in OSX 10.10.5 without a problem, stress tested and everything.

 

Thanks in advance

First guess would be a power issue. What PSU are you using?
What are you Afterburner settings? Did you increase the power limit a lot?

@Dschijn Everything is stock, and I'm using a thermal take 500w psu.
I have everything on 0 and fans in auto. Power ussage set at 100%

Tbh, had the same guess, but I really don't know how to modify/verify GPU's power limits.

@Dschijn Looks like I fixed it!

Tested all driver versions until one worked just fine. Plus dismounted and built my rig all over again just to make sure there where no connection issues.

Driver version stable with it: 353.06

Will do more intensive testing later on, and modify thread to leave solution in the first post. Just in case some1 else is having a similar issue with a similar rig.

@davidexD Seems like it, but i really don't understand how a driver sudenly started messing with my voltage/power.... was so mad that nearly started building the desktop for myself instead of doing it for my nephews.......
 

But let's pretend this was the fix for the time being. As I said, will test it later on with a few games and benchmarks. Unfortunately I gotta go to my second job in a while.

Don't use the latest driver, go directly to the latest BETA driver! Latest normale driver can kill your Windows.

Glad that its working ;)

364.47 is the bad one, better use 364.51 Beta (not sure if they are only available on Windows 10).

@Dschijn 

@Enano

 

Good morning. I have got optimus working with my dgpu (750m) mbpr and a gtx750ti which I run off a 120w PSU ( plug n play ). Recently I have started having crashes despite underclocking the GPU to 98% on MSI afterburner. Do you think it is a driver issue ( currently have the 361.75 ) and is there anything you would recommend to prevent the power spikes which, as above, seem to be causing the crash?

 

Thank you

I think the most important setting is the power target, which has to be lowered.

Maybe the PSU gets very warm dureing intensive use and by that is getting unefficient and results in a lower output.

Try lowering the power limit and use a FPS limiter (you will not need more than 60FPS)

@Enano are u having crashes again?

 

@davidexD Not even once after downgrading the Drivers.  

 

@p3nzancef1ier Do you have anotherpower supply you could test the GPU with? It seems to be a power issue. 120w is bassically in the limits of what's acceptable for the 750ti.

 

-Are the crashes occurring all the time or only during heavy load? If this is true, use the kombustor and monitor the power usage on the after burner as you do so. That way you can detect at which point this is triggering. In any case, downgrade to the GTA V game ready drivers, which seem to be pretty solid ones for the 750ti according to quite a few users.

 

Also check the temp of the psu, if it's way to hot as @Dschijn mentions, it might be limiting the power output to protect your hardware from over voltage.

@enano i lowered the power target to 75 and Windows didn't crash, just crashed the game, i'll keep testing maybe i've found the answer.

@Dschijn Thank you will try that this morning, had not applied an FPS limiter, are there any you recommend specifically? 

 

@EnanoI am trying to the keep the setup as 'plug n play ' as possible, if an upgraded PSU is required should I purchase a desktop pc one or would it be possible to use a more powerful 'brick' ? The crashes have only started happening recently and the temperature of the brick has not been excessive at all. I am only concerned that if I downgrade the drivers below 361.75 I will lose the optimus support on my mbpr d750m, would this be the case?  Apologies for the bombardment of questions, as soon as I have perfected it I will put up a build description as I believe this is a great budget 'plug n play ' solution.

I have ordered dell da-2, will convert to a barrel plug and report back to see if I am still having problems! Hopefully the increase in power should help

@p3nzancef1ier Sorry for taking ages for me to answer, been really occupied lately. Yeah, that will work, a lop of laptop power supplies are over 200w and most gpus + pcie expansions use just about that. All you need to do is cut it and solder the adapters correctly for it to properly work. I used my desktop PSU since i simply made my eGPU project as a hobby luxury, but the one you mentioned is the most used one in the forum as far as I can tell. The moding is pretty simple to be honest, and if I'm not mistaken, the plug it comes with, perfectly fits the akitio box.

 

@davidexD where you able to find a proper solution? If the issue continues, can you specify your rig? It might be a bottle neck issue (really doubt it since the issue started a while ago for you).

Also, did you tested more drivers? for GTX 960 353.06 drivers proved to be the more eGPU stable ones. for your 750, I think it should be the ones released a few days after those.

If you need help when it arrives, I will gladly assist you with any doubt you have. Although, I'd prefer for this thread to be as clean as possible. So if try mentioning me in a more adequate thread or create a new one if you find an issue that haven't been mentioned yet. The community is full of raw gems :)

@Enano Hi there, so I am currently using the Dell DA-2 for my 750ti egpu though the game crashes have not stopped. I have even limited the power consumption on MSI afterburner and yet it does not seem to achieve anything...do you have any other recommendations? 

 

Thank you!

@Enano @Dschijn I have noticed that unlike with the previous power adaptor once the recent crashes have occurred there are no power 'spikes' recorded on MSI afterburner, suggesting perhaps it is a software/driver issue? If I downgrade to a 353 driver I am worried I will lose optimus ability as I am running a mbpr with a discrete 750m gpu...is there a workaround you might suggest?

@p3nzancef1ier  I mean, I'm using optimus perfectly with my 960 and those drivers, but the dGPU is disabled in my case. If you are trying to use the dGPU, iGPU and eGPU all together. I don't know a work around. Intel HD graphic will work with optimus with any drivers compatible with your eGPU to be honest. Since it uses it for the dGPU as well. 

 

BTW, are you using drivers for the 750 or for the 750m chip? Cause that might cause a problem do to power distribution being 2 "low". Also, if you will reinstall drivers, make sure to use the tool Nvidia provides for the clean up and erase the Nvidia folder with previous installations afterwards before downloading. That way you will be 100% that you are installing the ones you wanted.

      Hi all, 
       
      I'm green as here, but been closely following peoples implementations for eGPU and MBP. After finding some inspiration from P-Mac here, I decided to build one. I knocked this all out for around $600 AUD. Being from Australia, it was hard to come by a Thunder2 box. So I bit the bullet and bought one from the US as cheap as I could find it. Picked up a second hand MSI Gaming GTX960, the twin frozr fan edition, also overclocked edition, cost me $200. Grabbed a Corsair VS550 PSU too for $80. I'm pretty handy with electronics and good with a soldering iron so I thought, no worries mate. Anyway, after waiting 3 weeks for the Akitio to arrive, it finally showed up and I knocked this all out in about 1.5 hours. 
       
      Opening up the Akitio
      I unboxed the package, and opened it up. These things are TINY, I thought. I knew I'd have to open the case up to make the GPU fit, but jesus, the GPU dwarfs this thing. I removed the fan from the Akitio and set it aside, probably never to be used again. A lot of people have just bent the back plate of the Akitio away, then gaff taped it up, etc. I didn't like that idea, so I took to it with a dremel and cutting wheel with the box facing DOWN, as grinding sparks and PCB's tend to disagree with each other. I cut a decent line into the steel, then bent it away with some pliers, then fatigue snapped the cut line. 

       
      Inserting the GPU
      Pretty straightforward. Removed the 2 retainer screws for the PCI cards, pushed the card firmly into place. I re-inserted the two screws and nipped them up with a screwdriver. 
       
      Easy peasy. 

       
      Wiring up the CPU PSU
      Now, I've seen all sorts of dodgy behaviour like jumping PSU's on with paperclips. That's live power, flapping around sensitive electronic components. I didn't like that idea. I also didn't like the idea of chopping up the PSU cables in case I ever want to re-purpose the PSU. So, I bought a molex to something connector (I can't remember the name) and chopped the red and black wires off at the molex plug end, chopped the yellow and black at the something end. Got some automotive twin core 3mm wire and a barrel plug I bought from JayCar and soldered the red to the centre post and the black to the outer post. Heat shrink over the exposed solder connections and electrical tape inside the barrel plug to ensure that it didn't short out, BAM, one 12V barrel plug to power the Akitio. Plugged the PCI-E connector into the GPU, simple. To "hot-wire" the PSU, I used a jumper wire and two electrical bulkhead crimp terminals. They're a little big to fit in the ATX connector of the PSU, but I squished them up with pliers and they fit in there snug, no exposed metal to short out on the case, or anywhere else, with the added bonus of the entire setup being plug and play. 

       
      Plugging in and recognising
      I used the instructions here (see below) to get OSX to recognise and install the drivers. Followed the instructions, no problems. Had to go and disable system protection out of the recovery partition, but that's no biggie. I re-started, flicked the switch on the PSU with the eGPU plugged in, took a little while to get through the load screen, but away it went. I ran a benchmark on Cinebench, got 77fps which was an improvement over the 59fps I would get out of the GT750m. 
       
      Teething issues
      Being new as hell to all of this, I'm still working out how to tweak settings etc. I opened up WoW, being an avid player, and expected to be dazzled. I copped a heaping load of disappointment when my recommended settings went to 1 from 4, and the game ran like a wet turd. However, after some playing around, trying a different monitor, enabling automation of the eGPU in the script, I'm getting a solid 40-60fps at high, not ultra, settings at 1080p. 
      I'm having often problems booting out of sleep, the computer crashes and won't turn back on without a hard reset, no boot chime or anything. Sometimes switching off the PSU to kill the eGPU is needed to get into the OSX loading screen, then flicking it on once it's loading is needed. Sometimes it works fine. This seems to be common but I'll keep looking for fixes for waking up from sleep. Even with NoSleep enabled and not closing the lid, eventually it'll go dark and won't wake up. However sustained use and gaming doesn't kill the computer, so I don't think it's an overheating issue. Also keeping a close eye on temps everywhere and setting the fans to max when gaming, as I always do as these things overheat like crazy during gaming. 
       
       
      To be done
      At the moment the Akitio is sitting open on the desk and the PSU next to it with wires fucking everywhere. It's messy and cluttered and I hate it. I've got access to tools and equipment some probably don't, so I'm going to build a custom case for both the PSU and the Akitio, and put some nice big fans on it to keep it all nice and cool under high load, hopefully preventing the GPU from needing to use it's active cooling at all, thus letting it work without strain. 

       
       
      Any tips or advice would be great!
       
      Updates
      Managed to pick up a GTX 970 locally for the same price as I paid for the 960. Same card build, MSI Twin Frozr fans etc, slotted right in with no changes needed. Getting 57 fps on furmark within OSX, 82 fps out of cinebench, which is a slight improvement over the 960. I've upped the settings in WoW and it's running between 50-60 fps no worries. 
      I also installed windows to try and get some benchmarks done, however furmarking is crashing the whole show and requiring a hard reset. I can get furmark to run in OSX though through some command lines found from the guys at geek3d.com. Windows has way more trouble posting the eGPU from startup, and has A LOT of trouble rebooting/shutting down. Really re-enforcing my love for OSX but I would like to play some higher end titles that simply aren't available on OSX in the future. Got Unigine to finally install (had a lot of issues downloading the entire file for some reason) and ran that on the 970. Didn't get to test it on the 960.

      Hi!
       
      I've currently got my Akitio Thunder 2 + MBPr setup working beautifully with Windows 10 - except for one annoying issue.
      Sometimes when I boot up Windows 10, the OS will try to output on the display output of my eGPU (GTX 960) instead of on the internal display.
      This means that I can't log into the OS and that I have to force-reboot.
       
      Sometimes I time the bootup correctly, and everything works perfectly, but sometimes it doesn't - which is very annoying.

      Do any of you guys know a way to force Windows 10 to use the internal display - always - even if an eGPU is plugged in (basically forced Optimus)?

      Hi, everyone!
      Today, after two days of torture, I set eGPU. But the joy was short-lived...
       
      However, in order:
      I have Acer v3-571G with dGPU GT 730m. I deactived this card in Setup 1.30 that i can use Optimus with eGPU.
      eGPU: GTX 960 4GB. (EXP GDC v 8.3)
       
       
      But after the test, I was confused.
      All due to the fact that the MSI Afterburner has shown that the GPU is used by 98%, but the GPU is not involved at all. 0% Always
      I test in CS:GO, Watch Dogs, GTA 5.
       
      In Watch Dogs eGPU better, but I think it can be more.
      In CS:GO, my dGPU was much better... 
      In GTA5 results are approximately equal, but eGPU a little bit better.
       
      I expected more from this decision. It can is possible to solve this problem? Maybe I made a mistake during the installation?
       
      Best regards.

      Hello all,
       
      I am new in this area (eGPU) and have some issues. When I Google my problems, this forum pops out to me. After review some posts, I still cannot figure out my problems, so I decide to register on the site and ask my questions here.
      Those are my parts: 
       
      Lenovo Thinkpad x230 with i7-3520M, 16GB RAM, Intel(R) HD Graphics 4000
      EXP GDC BEAST, Expresscard
      EVGA 500 W1 80+, 500W Continuous Power, Power Supply
      Gigabyte GTX 960 Overclocked 4 GB GDDR5 Graphics Card GV-N960WF2OC-4GD

       
      My problems are:
      When I pluged in the Expresscard, the computer can catch the graphics card, and it told me to restart the computer if I want to use it. After I restarted the computer, it worked! The fans on the graphics card spun, and I can see the screen in the external monitor, and it showed me that I was using GTX 960 now. I tried to watch the movie, and it worked well. But the fans on the graphics card stopped spinning. I am not sure it is normal or not, but my computer still worked fine.
      HOWEVER, when I tried to play the video game, it worked at first. But after about half hour, it would suddenly shut down, then restart the computer. At this time the graphics card did not work, so I have to use the internal LCD. I was trying to re-start the graphics card, but it still did not work and it was a little warm. I have to wait for some time to use the graphics card and the whole kit again.
       
      Does anyone know how this happen? It worked for a long time for movie(at least 1.5hrs), but it only worked for 30min for game.
       
      I also tried to change in BIOS. Inside "POWER" I think there is "PCI Express Power management", and the default is "enable". I tried to change it into "disable", but the result is still the same. I tried this change because I thought this is referred to "Disable PCIe Power Saving", but I am not sure. Or does anyone know where should I change?
       
      I would very much appreciate your help in this case.
       
      Thank you in advance!
