I've seen some crashes on core17 and driver 13.4 when i game, not only with my card but some other video cards too.

Have a nice day,

Turning on verbosity=5 is not helpful. We recommend setting it back to the default of 3.

The 0xc0000005 error is often a hardware error (overclocking? bad drivers? etc.) but they're not easy to diagnose. AMD seems to still be working on their drivers and the latest version may or may not be backwards compatible with core_16. A different version may help but nobody else has reported this problem.

Project: 11292 (Run 8, Clone 93, Gen 39) has not been returned by anyone yet, so we'll have to wait and see what happens when it is reassigned.

The last driver to work well with core 16 was 12.8.

I've tried the 12.8, 13.4 and 13.8b2 drivers without any luck.
I clocked my gpu to 300mhz core and 150mhz memory and it still crashes almost directly

This is some extra crash info:

Have you used one of the driver cleaner type utilites to clean the system between version changes?

Re: core 16 crashes

Posted: Wed Sep 04, 2013 7:05 pm
by benj1989
yes, i used the amd cleanup utility
i'm going to run a complete memtest86. i did run it for a while some time ago and didn't let it finish, but it showed no errors then

Also try memtestG80 for the GPU. http://folding.stanford.edu/home/download-utilities/

cool
memtest86+ did run more than 1 pass without any errors
i will try your gpu memtest, thank you :)

so the cpu folds fine for now
and i just got the core 16 running, it completed the first % already
i uninstalled the intel 2013 opencl sdk and that solved the problem, i guess this is more a fah problem?

i still will need to investigate why the gpu crashes when i fold on it while gaming (it has a lot of reserves since most games have an option to lock on 60fps)

ok right, i ran memtestCL (memtestG80 crashes directly). It gives my a lot of errors on the random blocks on 12.8 and 13.8b2 so i guess my card is bad..

gaming and folding also makes my machine crash with 3 other 7950's, maybe 550W isn't enough after all..

When it's fully developed, OpenCL is expected to work on a variety of devices. Here at FAH, we're only concerned about OpenCL on NVidia GPUs and on ATI/AMD GPUs since that's the only devices that we've successfully tested with the FahCores. Drivers provided by NVidia and AMD are required, of course, and as new GPUs are developed, the driver developers often have to make challenging changes to their drivers.

There's no logical reason why OpenCL won't run on an Intel GPU or, for that matter, on and Intel CPU. In your case, you installed the Intel OpenCL drivers so Core_16 might have been trying to use your Intel hardware when it encountered problems -- at least it wasn't running successfully on your Radeon HD 7970. The word from FAH's developers are that they may support Intel hardware someday but at the present time, either the Intel hardware or the Intel drivers still have enough unresolved issues that it's not something they're ready to develop. Given that information, the Intel OpenCL SDK isn't useful for FAH, and if it happens to present an additional device that FahCore_xx might try to use, you would need to be sure to avoid having it try to use that device.

Though I don't recommend it for everyone, if you do wish to do additional experimentation with Intel, you can reinstall the sdk along side of the necessary AMD or NV drivers and experiment with FAHBench. It can provide a great deal of information about the recognizeable drivers and devices on your system. You can test each one separately since the necessary device numbers are reported.

MemtestG80 is not expected to work on Radeon hardware. It will be expecting a G80 device with NV drivers and you don't have either one in your system.

In your case, you probably now have only one device with OpenCL drivers so the right device will be selected using the right API.

having the intel opencl installed causes fah choosing that instead of the amd one

on memtestCL i have huge amounts of errors on the random blocks tests on 12.8 and 13.8b2, i will krank my case open soon and test it with a 7950

FAH does have problems when it is forced to choose between various OpenCL devices. The only method that works is to manually adjust the value of opencl-index so that it points to the correct device. FAHBench CAN help you determine in what order that the devices are detected ... or you can use trial-and-error, with the additional knowledge that <opencl-index v='0'/> currently points to (one of) the Intel device(s) in your system.

Running Linux or Windows or MacOS with exactly that hardware may very well configure those same devices in a different order, requiring V7 to be smart enough to figure that all out, and there are open tickets associated with the latest client version.

i tried to adjust the opencl index to 0, 1 and -1 and it didn't make any difference
and for the memtestCL errors, apperently they are normal for the 79xx series

I must be missing something for my read of the original post is that Core_16 is the problem not Core_17 and/or OpenCL (other than while gaming). All the reply posts seem to be dealing with Core_17 and OpenCL. Core_16 does not use OpenCL. Gaming (or watching GPU-accelerated videos) while simultaneously GPU folding is generally problematic. So I am confused as to what the actual subject of the thread/issue is.

ATI only supports OpenCL beginning with the HD 5000 series. Prior to that, they supported Brook. [The HD 4000 series is a bit of an anomaly, but that's not significant in your case.] ATI's OpenCL API is supplied with the drivers for your Radeon HD 7970.

FahCore_15 uses OpenMM plus CUDA for NV
FahCore_16 uses OpenMM plus ATI OpenCL
FahCore_17 uses OPENMM for NV (possibly using CUDA/possibly using OpenCL) and OpenCL for ATI.

Core_17 seems to work best with the latest drivers (including the latest version of OpenCL). Core_16 was developed using earlier versions, so there seem to be various opinions about which drivers might be the best. Unfortunately, OpenCL is still a bit of a moving target but ATI is a very ardent developer.
