Every time I try to create a model using “high quality” setting, My computer crashes after a few seconds. No warning, no blue screen, just off. Thought it might be a power consumption issue, but removing 2 of the 3 video cards did not change anything, except it takes a little longer before it crashes. Nothing else on here crashes the computer, even other similar programs that stress the GPUs like RC. I found the RC log, but it is basically empty, but logging is turned on.

Hi Michael Agronin
If you are experienced, then look at the EVENT VIEWER for CRITICAL ERRORS and put the info here… So that we can pinpoint the issue…
Today I have exactly the same problem, change video card from a GTX 780, worked well, but now upgrade to a GTX Titan X card and every time I give calculate model the computer without warning goes off, and probe with different programs to verify the card and all work fine, the problem is only with RC. Every time I try to create a model using, My computer crashes after a few seconds. No warning, no blue screen, just off.
Hi Diego Torrijos
In your case it looks like a PSU issue…
Fill out this http://www.coolermaster.com/power-supply-calculator/ and post the results here…
- ucp.php?i=profile&mode=signature put you PC config in your signature
How old is your PSU ?
Hi Wishgranter,
Thanks for your quick response.
Power-supply-calculator:
Load wattage=805 W ; Recommended PSU wattage=855 W
My PSU Dell 1100W Power Supply.
Perform stress tests of the GPU and all good, perform extraction points in ultra resolution with the evaluation version of Agisoft and works well, perhaps RC requires more energy, the problem is only with RC, and just seconds after start calculation model.
Hi Diego Torrijos
How old is the PSU ? In principle, RC uses the CPU and GPU much more efficiently. even when you see 100 % utilization in agisoft it does not mean your CPU - GPU is working at 100 %
The problem with PSUs is, even though they say 1000W, in reality you get much lower wattage, as it generates 12-5-3V and so you cannot use the full 1k Watt. If it says 855W, then you need at least 1200 Watt PSU… I am using 1300 W PSU but I keep the load under 800W.
Look at the 12V rails amperage ( Volts + Amperes = Va = Watt ), highly probably it is a PSU-related issue…
Try to remove some HDDs or GPUs, if possible, and test it again, it should be able to work without crashes…
Look at the EVENT VIEWER for critical errors , if it is Err41 power outage, then it is 100 % sure the PSU
Wishgranter - Thanks for the reply.
I’ve looked through the event log - your suspicion is correct, all the critical events are Error 41.
I went through the PSU calculator and came up with 1075W with all three video cards in, and 744 with just one. With the 1300W PSU in there, it should be fine with either situation, but crashes with both. I’ve contacted Dell, and unfortunately its a proprietary supply and 1300W is the biggest they make that fits.
Hi Michael Agronin
with the PSUs it is a pain 
The main problem is your PSU probably cannot deliver enough watts to the CPU or GPUs per power line ( from PSU )
Go to RECONSTRUCTION ->SETTINGS -> GPUs to CHOOSE button and deselect ONE or TWO GPUs and try to reconstruct it.
So what you can do if it is a PSU ? you could eventually use TWO PSUs in your PC ( is it possible ? ) or get more powerful 1500w PSU, or change the 980 for the new 1080 GPUs, as they need much lower wattage ( and you will even get significant speed-up )
Maybe you should look into the RC code, my computer is a Dell Precision also, but all applications work fine, except RC, is the only one that crashes.
Hi Diego Torrijos
No need to look in the code, we know it’s working properly, but, as you can see, more users have problems with their PSUs.
The thing is we use CUDA sw that is very EFFICIENT, so it uses the GPU quite heavily -> a lot of energy is therefore used…
In games and much sw you can observe 100 % GPU utilization but in reality it works at just 50-60 % of the possible performance, so you can‘t get power issues there… RC has been made with max performance in mind so it uses all resources and it‘s very effective…
I highly recommend you to read a bit about this stuff here:

GeForce GTX Titan 3x SLI - on your average system the cards require you to have a 1000~1200 Watt power supply unit as a minimum.
Hi Diego Torrijos
I have a question as I see you are using OLD Xeons the X5690, is the PSU the same age ? I mean is it 3-5 years old ?
Wishgranter - I pulled 2 of the GPUs out of the machine, running with a single GTX980 to test. Same exact crash. You’re telling me that I’m overloading a 1300W PSU with a single GPU? This does not seem reasonable. According to coolermaster, it should be drawing ~750W peak with 1 GTX980 installed.
2 PSUs is not an option with this machine, and due to the proprietary nature of the PSU design, I cannot even upgrade beyond 1300W (not that it should be necessary).
1080s are in our future for this machine, no question. Just another couple weeks…
Hi Michael Agronin
When it crashes even with SINGLE PSU, then you have some real problems with the PSU.
This cannot happen with a new properly configured PSU…
Can you send me PRECISE info on your PC + the PSU ?
It looks like a not properly “connected” CPU + GPU to PSU, but I can say more just when I see the detailed PC + PSU info…
Not talking about games. I speak equivalent testing programs, Agisoft PhotoScan and Pix4D, all perform under maximum load, but RC crashes.
Hi Diego Torrijos
I’m quite experienced with all the mentioned sw and KNOW how they work on the GPU side of processing data. do you know that Nvidia is BLOCKING performance under OpenCL in drivers by 50 % ? ( from 286.xx version of their drivers ) so even though it says it’s using the GPU at 100 %, in reality it’s lower than 50% ? so it can’t crash under the load you mention. It’s NOT possible. Look for good GPU monitoring sw, like MSI afterburner, and have a look at it at least there…
Download this http://www.ozone3d.net/benchmarks/fur/ and stress test you PC config… This one can get to GPU use like RC can do…
and send me the PC config + detailed PSU info please…
Doing some testing this morning. With all 3 GPUs enabled, I crashed RC running high detail. I’ve a Killawatt PS (1800W max) hooked up to the PSU. It reports real time power consumption and records max levels. Peaked at 680W. Tried again with just 1 GPU enabled, Peaked at 530W.
It’s a Dell Precision T7610 with 1300W PSU. Unfortunately, I don’t think there’s much more I can provide in terms of info on it - it’s proprietary, and Dell is pretty useless (I was talking to them last week about this issue, and they told me several times it was standard ATX PSU, despite the fact its an odd form factor with a hot swap blade connector).
I will run the ozone3D benchmark and see how that goes…
Hi Diego Torrijos
And I have asked you how OLD is your PSU because the PSUs are aging and losing 5-10 % of their capacity per year… so if you have an OLD PSU, it can be at the end of its life, which is common these days even for pricey models 
Look how it is connected to the PSU RAILS whether the rails have ENOUGH capacity to feed the GPUs ( CPUs )
Minor update: This machine also is actively being used with Agisoft Photoscan. Just glancing at the Killawatt - it peaked at 830W running PS without crashing.
Hi Michael Agronin
if you can take a look at the RAILS connection and their amperage, that can be the issue. if you overload rails, then it can get in this issues as it can’t deliver the required power and it shuts down…
I’m speaking from my own ( 20-year experience ) with PC assembling. Even my Dual Xeon (overclocked ) is a custom-made PC
How do you suggest checking the AMPERAGE of a RAILS? Generally you need to have an ammeter in line to get a reading on that.
Are you suggesting that CR only works on custom made PCs? Is there an inherent problem using DELL computers with this software?
