I'm getting this issue when I try to render hair in 3D view, but it render well in final render:

OpenCL error (-61): CL_INVALID_BUFFER_SIZE in clCreateBuffer

My system: Rx 480 + Rx 470 in Blender 2.78c

It happens in each one alone and with both together with or without Crossfire.

Please follow bug report guidelines and provide:

Exact operation system you're using.
Simple .blend file which demonstrates the issue.

Additionally please make sure you're using latest drivers available and test builds from builder.blender.org since there were lots of fixes since 2.78c.

Exact Operation System:

16 GB DDR 4{F626319}
AMD Rx 480 + AMD Rx 470
Blender 2.78c stable (Sorry, I can't try building version. I've lose two 3D cards with it).

This is the file: https://www.dropbox.com/s/6rqflvp0i7i7f25/test.blend?dl=0

@RenatoMeneses what do you mean, you cannot try testbuilds??? “I’ve lose two 3D cards with it”????

In any case, we have to know whether issue is reproducible with current master before doing any investigation, no point on losing time on some months old release ;)

I have burned my PC twice when I have used Blender building version. I'm not sure if it was really the Blender that have caused PC burning, but within 15 years I have lost 2 computers only when I was using test building versions.
Is it possible when website says "do it with your risk" ?

That is very, very unlikely to be related - and definitively not to be expected. Odds some code might lead to burning hardware are really low, thermal protection is supposed to be hardware-managed (or at worst, driver managed), i.e. totally out of scope of regular software influence…

The warning message on our builderbot website refers to possible .blend file data corruption due to a bug or some compatibility issues. While we are fixing such issues quite quickly it could still have negative effect on your production.

@RenatoMeneses it is indeed very unlikely to happen. In very intensive rendering scene, cycles uses max 85W on my RX480, while the card draws 160W (above the 150W of PCIE specs) while rendering real time benchmark scenes like furmark. Cycles heavily underuse the GPUs (on both CUDA and OpenCL) compared to real time 3D apps, especially benchmarks. So the only thing that could burn it while rendering would be if your fans are defects, but even then, the hardware should just shut your PC down to protect it.
Whatever happened, it's not the software job to monitor temperature. Also note that overclocking, changing voltage and all other modification leading to warranty void are allowed by drivers from all vendors, but are risky and thus not supported. So I would recommand you to use latest build, which is much faster for your configuration anyway, but leave all driver options at defaults.
2.78c is not supported anymore. But I'll let @MaiLavelle and @Sergey decide here.

Thank you so much guys! It's working pretty well in the building version!

Many thanks!

Great work!

Now I have noticed that this new building version (2.785 Render Time: 09:03.70) is rendering this file very slowly than stable version (2.78c Render Time: 01:08.78) this file: https://www.dropbox.com/s/6rqflvp0i7i7f25/test.blend?dl=0

with 256x256 tiles (recommended size in the manual), using latest master and latest drivers from AMD on win7 x64, your file render in 1min46 with one RX480. So it would be 53s on 2 cards, which is faster than the time you report with 2.78c using 2 cards.
Second thing is that BPT wasn't available for the split kernel in 2.78c, so the file couldn't render.
Setting as incomplete until more informations are provided.

OMG!!!
What should be happening here???
I think new version of Blender works better in Windows 7.
I have putted 256x256 now, but anyway 07:05, see:

hhmm.... very weird.. I think it's solved...
The first time/frame takes more time to render.

Anyway it's going better with Official version (time: 01:02 in v2.78c):

read the docs, read the text writen in the UI (it writes kernel is compiling when you render for the first time), read the answers the devs write (there is no BPT in 2,78c = it uses normal PT = it is faster. Use normal PT in 2.79 and it will be much faster. You will help make Blender better by doing your part of the job correclty!
