Project: 6811 (Run 0 Clone 139 Gen 1) fails due to nans

[shunter]

I have run some 380 units (including 6800s) on this GTX 460 with no problem but got my first 6811 yesterday and so far it has failed about 10 times due to nans being detected. Normally this happens between 9 & 11 % but once it got as far as 55% and other times it has been as low as 6%. In the past I have deleted unit and reloaded a few times and get a new unit then report the old as possibly faulty. This time I have been unable to do this - I am not cherry picking but if I cannot complete this unt and cannot get another there's no point in folding on this card - any ideas / suggestions please?
Thanks
Shunter
PS Can provide logs if required

Is your machine overclocked at all? If so, try running it at stock speeds.

[shunter]

PC definitely overclocked as its from OverclockersUK and an i7 930 running at 4011 MHz. Not sure about the card but believe it may be but as not a real techie I'm not sure. Is there anything I can run that will tell me?
Thanks

[HenryW]

Yup, download and run GPU-Z and it give you all needed info on the graphics card. While you're at it you can download MSI Afterburner to adjust GPU core clock if needed.

There is no data back on Project: 6811 (Run 0 Clone 139 Gen 1) yet, but I'll mark it for followup checks.

Thanks for your report. It's always a good idea to use the -verbosity 9 flag and to include your relevant logs when posting a trouble report, as well as your machine specs and info about overclocking and/or other special configurations.

[shunter]

Thanks for the replies.
Card is a GTX 460 running at default per GPU-Z, ie clock 763MHz, Memory 950MHz and Shader 1526MHz. I've never had much luck overclocking my own so if they are then I have bought them in at that level. This is the first project on the card that I have noticed card fan varying in speed of operation.

Have started unit again and its failed now at less than 1% - extract of logfile is below

NaNs can be caused by several different conditions. The fact that it's happening at different points in the same WU makes it unlikely to be a problem with the WU itself. That leaves "hardware" which may mean (A) too much heat (B) too much overclock or (C) defective hardware.

The most likely seems to be heat. First, I'll assume that the manufacturer who assembled the GPU on a board used the reference design -- a 2-slot board that blows the heat out the back of the computer. Is the air coming out there quite hot? Is the inside of the case quite hot? Are all of the case fans operational?

You said the GPU fan was changing speed. I've seen a number of cases where the fan profile didn't set the fan speed high enough. You may need to do that to keep the board cool enough.

I'm using MSI Afterburner. It's a tool used primarily for overclocking but it also gives you the ability to monitor the temperature and the fan speed and, if necessary, increase the fan speed. There are other tools which provide similar options.

There's also an environment variable FAH_GPU_IDLE which can be set to 5 or 10 which can reduce the percentage of time that FAH folds, thereby reducing the heat, but you probably don't want to use that option permanently if there's a better choice.

Thanks Bruce.
From what you say it appears to be Hardware. Per GPU-Z its an EVGa (3482) and its the standard design running at default. Air exhausted is hot and again per GPU-Z its running at 98 C and fan at 100%. System is also running a 6701 on the CPU core so I assume thats adding to the heat issue - this will finish at 7.30am tomorrow so will set parameters to include oneunit here to give more scope if the GPU is still running later tonight. In the meantime I have used your FAH-GPU-IDLE suggestion and severly restricted the running time to see if I can get through this unit.

I'll look into MSI afterburner - probably a stupid question but can it be used to tune down a card so that I can run it at a lower speed / temp and complete the unit that way.

[bruce]

I just checked and FAH_GPU_IDLE doesn't work yet with Fahcore_15 thought it will in some future version of the core. (And it will never work if you call it FAH-GPU-IDLE)

Yes, MSI afterburner can be used do underclock a GPU. 98C is too hot. It shouldn't melt the silicon, but you will get errors.

I'm surprised that EVGa has such poor cooling at a 100% fan setting.

My 460 is currently running a 6800 and it's different enough from the 6811 that you can't really compare performance, but it's a 82C with the default fan profile (currently at 56% fan). We can see if I snag a 6811 in a couple of hours.

[shunter]

Sorry Bruce, that's my bad typing - I'm sure I set it up correctly but if it's not working then it's no use. Funnily enough after that the fan settled down to a steady rhythm and folding ran perfectly overnight. At 7.07 am the CPU core completed and closed down and then at 8.51 am the GPU crashed again (see log below) so am back to square 1.

I'll have to look into the EVGA running too hot but as only been monitoring temp for last day or so I don't know how hot it's been running on the 6800s and need to get inside the box. Just recovering from eye op so that will have to wait until I can see more clearly - probably that and dyslexic fingers also explain bad typing .

Thanks again
Dave

Yup, that's way too hot and more than likely cause of failure on that WU. Down clocking will reduce temperature but folding time will also increase. I had a 250 GTS last year that was doing exactly the same as yours is and an added side case fan fixed it.
Does your case have a left side panel fan blowing on the VGA? If there's a place to install a fan in the side and none is there I would recommend you put one in blowing on the VGA. You should currently have at least a front 120mm intake and a rear 120mm exhaust in the case in addition to the PSU fan(s). My MSI 460 HAWK Twin Frozr ll @ 875 core clock folding 6800 is 58C/58% fan speed. I just installed this card 2 hrs ago, had a MSI 465 prior to this. Beginning with an MSI 260 OC Twin Frozr, 465 Twin Frozr ll and now the HAWK Twin Frozr none of them have gone over 60C when f@h. As far as I'm concerned that's the best cooler on a card for f@h and I'll never use anything else. There are replacement coolers you can get that look to be similar but not what one would call inexpensive.

Anyway try everything you can to get the temperature down and that should fix your stability problem. Another thing that could be a contributing factor is a weak PSU. Do you have any idea what brand, model and amps on the +12V rail(s) that it has?

Edit: I forgot to add you can get Afterburner here, http://downloads.guru3d.com/Videocards- ... g_c13.html

CUDA allows developers to create code that is extremely efficient. If you're asking them to slow down everybody's processing (say by setting the default value of FAH_GPU_IDLE to 3% once they make it work correctly, I don't think that's a realistic request.

Many people are able to run effectively with the current settings. Currently my GTX460 is running a p6811 at stock settings. The default fan profile setting is 70% at 73C. Clock rates are at the default 675/1350/1800 and it shows 100% utilization. (In the past I've had it up to 825/1650/1800 without any errors.)

Perhaps there's a systematic difference between the cooling solutions provided by Asus/eVGA/Galaxy/Gigabyte/MSI/Palit/Sparkle/Zotac (etc?). I do know that the 768MB GDDR cards use less power than the 1GB DDR5 cards. Perhaps it's the VRAM that's generating more heat or the fan that's not moving enough air or the heat-sink that's not doing its job.

If everybody is having the same problem, then maybe FAH should make their code less efficient. (They'd have to tell NVidia that CUDA is too efficient and that it's a generalized problem.) As long as it's a problem that you have and I don't, though, it's going to be something that the company that assembled your GPU board (or maybe just you) is going to have to address, not FAH.

I'd start with a RMA request to the board manufacturer saying the fan isn't providing adequate cooling when running FAH and point them to this topic for documentation.

We should probably start collecting data about brand X compared to brand Y and see if we can identify a systematic cooling problem, but there are enough other variables in any cooling discussion that the data probably won't show particularly clear trends.

EDIT:
I have been reminded of another factor that needs to be taken into account. There must be a good thermal fit between the heatsink and the GPU. Anybody who has worked with computers very much knows that the thermal grease must be high-quality, must have a very thin coat, and if you really want a good fit, maybe you need to lap the CPU and the heat-sink. Then the heatsink mounting must maintain a good fit so the heat gets transferred to the heatsink.

Some manufacturers use really cheap thermal grease, do not apply it sparingly, and certainly do no lapping. If you attempt to fix this sort of problem yourself, you will void your warranty . . . and you may or may not be successful. If you return the board to the manufacturer, they may do it for you or they may replace it with a different board that dissipates heat more effectively.

I have personally re-seated a factory installed CPU-heatsink that was originally installed with thermal compound more that 1mm / 0.40" thick. It's amazing how much cooler it ran after that.

Henry / Bruce,
Thanks for all the info and advice given which I will be looking into when recovered from op enough to see what I'm doing in the box.

In the end I stopped CPU folding and ran a household fan through the side vents to keep temps down but still ran at between 92 & 96 which is far too high for future units so temporarily have removed advmethods from the flags until I can monitor temps and make changes. Unit eventually finished a few minutes ago and submitted so am now running a 6800 and without any side fan the system is cruising along at 77 - 78 C even with CPU folding a 6701 which seems ok to me.

Thanks again
Dave

I have a simple solution, manually adjust your fan speed to 60 percent or faster and watch the nan problem fade away. Works for me.
