A quick Google search and this is the best I've found concerning GTX 780 temps.

http://www.anandtech.com/show/6973/nvidia-geforce-gtx-780-review/19

Interesting snippet from the above page:

Quote With GPU Boost 2.0, load temperatures are kept tightly in check when gaming. The GTX 780?�s default throttle
point is 80C, and that?�s exactly what happens here, with GTX 780 bouncing around that number while shifting between
its two highest boost bins. Note that like Titan however this means it?�s quite a bit warmer than the open air cooled 7970GE,
so it will be interesting to see if semi-custom GTX 780 cards change this picture at all.

And that review, while dated now, was with an i7-3960X on a superb EVGA X79 SLI motherboard. No slouching there, that system didn't hamper the card in anyway.

I am not a GPU expert either, your old motherboard and CPU was "older', without knowing what you had previously.

I don't understand bottlenecking, yet I can not believe for one second the current system it's in would be a bottleneck to it.




Anyone???? I haven't a clue.

Does bottlenecking cause the card to physically slow itself in recognition of it being hampered by a/the lowered bus throughput? On whatever the OPs prior system was.

No, bottlenecking will not cause the GPU to alter it's clocks in any way. The bottleneck occurs when the GPU is starved for data by an inadequate CPU or PCIe bandwidth, this results in stutter and spike behavior. Until fairly recently reviews did not even test for this. Quite often you will see a higher average FPS and a stupidly high maximum FPS when a bottleneck is present but the minimum FPS will be very low and occur frequently. The result, despite the highish average will be very choppy gameplay with loads of stutter. The high FPS spikes will occur immediately after a stall as the CPU suddenly dumps a load of frame data onto the GPU which up till that moment was idling waiting for data. I suppose depending on how long the GPU was starved for data it may briefly lower it's clocks a performance level but it would be for no more than a second or so, not enough to significantly affect thermals.

There is also no way that CPU would bottleneck a GTX 780 and no way the GPU should be running hotter on the new system unless there is some kind of issue.

Is the BSOD the only error you are getting Franco? Do you get any "the display driver has stopped responding and been recovered" messages? This is usually the message you would get if the GPU is broken, defective or the driver is bad. 

IRQ not less or equal messages are usually memory or hard disk related so it may be worth while reseating your CPU an checking for bent/misaligned pins while you are at it. I have seen quite a few issues on X99 platforms that were resolved by reseating the CPU. Make sure your CPU cooler is not installed so tightly that it is causing the pins to miss-align.

Good luck

I looked up question on GPU temps.

The Nvidia site has specs on all their gear.

The link:  http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications

So I think I am ok, although I can check again after the memory test.  Looks like 4 hours per Pass, btw, and I am only through the first pass (with no errors yet)

Here is a copy of the GTX 780 specs:

Thermal and Power Specs:

  250 WGraphics Card Power (W)
  600 WMinimum Recommended System Power

I think I will try a CPU-reseat.  The cooler is that Noctua D16 and is bigger and heaver than any I have ever used.  On the question of other errors - no - there has not been a single hiccup on video errors or anything else.  The installs have been clean and error-free, especially since I have done three separate clean Windows 10 pro installs on this system.  

Again, thanks for the excellent input

No, not a single one. It still doesn't mean a 100% certainty my memory is okay, but since this is just my personal computer I at the moment use for random stuff, there's really no point in running the test for weeks.

Quote My BSODs usually show up within 4-5 hours of running, sometimes within a few minutes of startup.  So I thought 4 or 5 hours of continuous memory tests with no errors would clear the memory.


Unfortunately it doesn't quite work that way. If the error is intermittent, then it may in principle take anything between a few seconds to several days (maybe even longer) for it to occur, depending on the severity of the issue.

Quote But it only takes time so I will let it run all the way next time.  I know I made it to the 4th pass but I don't think it completed all the way.


You can also run more than four passes if you want. The more passes you run, the larger the chance to encounter an intermittent error. The fact that you have already seen an error once should mean you had an issue with your memory and the persistence of the BSODs is in my opinion a sign that the issue hasn't really gone anywhere.

By the way, what was that single error you encountered the first time you ran MemTest86? I'm not sure if MemTest86 overwrites the logs it creates on the bootable USB, but if it doesn't, you should be able to find the logfiles on the USB stick and see what the error was.

Update: 
Just finished full cycle of 4 passes in a little over 23 hours of continuous running.  
No errors were found.  This is with all 4 sticks in place - 32G total.

Passed huh? Well, hmmm

Frank, do you have a 4-pin molex plugged into the motherboards PCIE_PWR1 ?  That might be advisable to try plugging one in there before re-seating the processor.

Wardog,
I could plug in the PCIe power - I did not do that since I have only the one card and the manual describes using it for '3 or more graphic cards'.  What is your thinking on it? Lack of power causing some kind of instability resulting in the 'IRQ NOT LESS OR EQUAL' error?
 It is a bit of work, but I already have a couple of weeks of effort into this build already anyway.

Frank, I've seen stranger things be resolved with only plugging/powering this connection.

Everyone's system is different. Number of PCIe devices, how many "splits' off a PSU rail, and maybe to some extent the differences in PSU design and manufacturing.
