New AMD APUs... [AMD A8-Series]

Quote from: epenue on October 21, 2012, 09:23:00 PM

Trying yo mine with one of these (3870K) and its just impossible;

i get 3MH, obviously GPU is doing nothing,

The problem i think is that i mine in Windows XP64, i have installed latest SDK available, 2.3, but with guiminer - opencl i get only 3MH, and trying to mine from command line i get this error:

C:\guiminer>poclbm
Traceback (most recent call last):
File "poclbm.py", line 48, in <module>
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code

All help i find about that error is for linux based systems,

any help?

Thanks,

You need to install the latest Catalyst driver (cleanly). Uninstall that SDK shit and any other AMD software first.

Yes, that was the first thing i tried, only catalyst, in a new system, latests version, but guiminer told me that no opencl device was installed, and from command line things didnt work also; then i tried with SDK Huh

My only other guess is XP is the problem. You should be able to buy 7 cheap now that 8 is coming out.

Unfortunately thats not possible, i use these machines for other production works and they must use XP 64 Sad

no other ideas? anyone? Roll Eyes

Put 7 or linux and run XP 64 in a VM?

Not possible; but maybe the other way around... Grin

A VM does not (usually) have access to the GPU... They use to have a generic GPU, but not the actual hardware...

A VM for production use isn't a good thing ... USB and serial pass through is not guaranteed to work. If it works ...

A8 is not the newest highend APU, A10 is. I have a friend with an A10-5800k(integrated 7660D) and it pulls just over 100mh/s.

You could possibly use IOMMU passthrough stuff to get "native" access to the GPU, but not with XP as the base OS :-(

not with any home operating system

100mh/s?

That's barely better than my 3870.

Considering it is sharing the die and TDP with the cpu, it isn't bad.

These chips also scale linearly with system memory performance. So try and get your system memory as fast as you can for best performance.

The bitcoin hashing algorithm isn't memory intensive at all, so I doubt it would scale much with higher memory speeds if anything at all.

You know, you are absolutely right about that. They shouldn't matter. A friend of mine tried a 3870K on stock settings and got 70Mhz. Checking on the Bitcoin wiki they show 100Mhz, but they overclocked the CPU. Memory was only at 1667. I jumped to conclusions because of the graphics performance and its reliance on memory speed.

I amend my original statement, for everyday 3D graphics performance, these chips scale linearly with memory clocks. Also for scrypt mining if you are into that (LTC). BTC should not be affected.

I also have a 2.9 ghz llano a8 3850. I can get about 68mhs from it with the flags -v 128 -f0 from guiminer. It is interesting because then I can also add up to 3 video cards to motherboard, I don't mine using the cpu at all.

I've got an A6 in the laptop I'm using right now. It averages at about 25MH/s, not much really. But fun to start out with.

I have one of the new APUs in a system I built last month, the numbers were not great. I'll see if I can find the screen shots from testing it.

That'd be great, i'm very interested in seeing some Trinity results.

I should come here more often Tongue

I have an A6 APU black edition at a 4.0GHz thoroughly tested overclock as a demo system at my shop and just built an A10 system yesterday. The 1866MHz memory is still on its way here in the mail but I'll stick some 1600 Ballistix in it temporarily, install Win7, and let you know what it gets for mining speed.
