GTX 1070 Driver Stops responding, stutters in stress test

No overclocking whatsoever, the drivers crash/reset after 2-3 hours of gaming, and stutters happen pretty much all the time, judging from the GPU load drops seen in the screenshot.

Only thing I remember doing is swapping the gtx 750 with this new card, but after that I reinstalled the drivers quite a bit. Gonna try a new fresh install of win10 or a win8/7 as I understand stutters get introduced to other gtx 1070 users with win10.

My other bet is that the low cost components this prebuilt system has, combined with the fact that it’s resealed item, resulted in a component having an actual defect that I’m not yet able to troubleshoot.

I got one more week until I can return this item but I badly want this GTX 1070, might as well sell the rest of the parts and build a new PC from scratch, but I want to rule out hardware faults on the GPU first.

That GPU is too hot. Pascal performance suffers dramatically past 62 degrees C. Now that 1070 has enough power, its drawing 75 W from the PCI slot and another 75 W from the 6pin; So its getting 150W total which is up to spec for the 1070. Although if its getting that hot under load then its efficiency is tanking. I would suggest undervolting/underclocking the card and try to get it under 70C.

Assuming I rule out a hardware fault, would it be recommended to replace the current blower fan with an aftermarket cooler on it?

You are right, reference GTX doesn’t seem to get well past 70+ degrees C under load.

I would tend to agree the card is running too hot. 82°C IIRC is the temp at which the card drops clock speed to keep temps down on the FE. I dont think that would cause the driver to lock up. I’ve never seen that happen to any 1070. I have my doubts about that power supply though. Its 450w but whats the 12v rail actually rated for? Cheap PSUs often bundle all of their rated wattages together to a max wattage they cannot actually deliver.

I would go with more case fans first. You have an airflow issue. You can replace the cooler on the card if you want, but its not necessarily going to lower GPU temps if theres a pocket of hot air in the case not going anywhere.

Noting is wrong with blower per se. But a better cooler would definitely help the card. YMMV, I think that card is custom.

Yeah its fine. The CPU draw is only 64 Watts, and the 1070 max draw is 150 Watts. So he’s sitting at around 225 Watts under full load. As to whether the PSU can handle the voltage ripple remains to be seen, we need to know about its efficiency rating.

A better static-pressure exhaust fan would help. Definitely needed if he switches out the blower cooling for once that churns the heat inside the case.

Sorry if it sounds stupid, but to make extra sure I get enough power, I also unplugged the power from my DVD Writer.

I have another bequiet! 580W lying around, gonna swap and try again.

here’s a close-up of the included 450w psu

and one of the card

specs of the card here: Lenovo, rebranded MSI GTX 1070, a few qestions

We can’t tell anything from that angle. We need to see the stuff on the side that is askew.

(Looks like 80+ bronze?)

Yes, 80+ bronze. Lenovo only has to say “Up to 450w” about it.

But if its 80+ bronze then you’re usually fine, with the caveat being that its only for efficiency. Where it can handle load-wise what it says is another story.

Totally fine. Its not churning out 450 all the time. It means that it can handle sustained loads, with the specific efficiency, up to that number (and somewhat beyond). So I don’t think its your PSU, unless it is actually bad.

Edit: for clarity. Thanks for the catch @MazeFrame :heart:

@nemuro after you’re done reinstalling stuff, could you give undervoling/unclocking a try?

I do know that also, You need to set your power settings in windows to High performance, otherwise the card might stutter.

I think you are probably on the right track with the VRM not having any cooling. I think were both on the same page with “needs more cooling”. I only actually see 3 vrm in the machine linked, which doesnt sound right but if true could be a real issue without airflow.

@nemuro I cant actually read the info on the side of the PSU there. Its not a high end one for sure but it shouldnt be crap either. I might suggest making your rear exhaust fan an intake fan instead. This will make it louder but should help VRM temps. You might also consider a new case for your hardware. It looks like the board is standard ATX so it should fit in most cases. It would give you better cooling options. I can only see 3 spots for fans in that case so your options are more limited. Perhaps noctua fans are in your future. I know the arctic F12 and F14 are also great fans if you are looking for something a little cheaper.

Efficency and power rating have nothing to do with each other!

If the rated power is 450W, it will put out 450W. It may draw more from the wall, put it will put out 450W

^makes sense, in a way.

I think hes mainly talking about those cheap non 80+ rated power supplies that claim 500w but would explode if you got anywhere near that.

Sorry I mis-spoke. But He’s well within his power target with a PSU with known efficiency. Maybe hes even hitting 300W with spikes, but even still he should be fine?

@Dynamic_Gravity Will do, thanks.

@Adubs You are right, Lenovo did obviously cut some corners here and there. I am actually planning on building a separate PC but keep the GPU, I wish however to rule out that anything’s wrong with it before that.

Aside from Heaven and Valley stress tests, any other software I should try to test the card that you can recommend to make sure I am not keeping a faulty card?

Who’s the manufacture of the PSU?

No idea, but judging from the sound it makes compared to my bequiet!, it’s a shitty one. I will take a look once I open the PC and let you know.

Do let us know.

Sometimes they just slap the sticker on there and it actually doesn’t do what it says it does. So we could just all be fooled. Unless you have instruments to test we can’t really validate, so knowing the manufacturer will help.

I was having the same problems with my 580 in windows 7 and 10 equally so I gave up trying.

Did a bit of digging, seems the card ships with a weak a** fan profile, and that combined with the poor airflow shuts down the card.

I remember ramping up the fans manually in MSI Afterburner made the card under load go around 70 degrees, without undervolting.

It’s amazing this is Lenovo’s idea of a gaming PC, 2 hours then you have to take a break, guess it helps with gaming addicts. Maybe that’s why the previous owner sent this back.
Hope this card check out, because it will be much happier in a decent case with a decent motherboard, airflow and PSU.
