Why does my hashing rate slow down?

[$1LK]

relevant specs:
-1x windows 8 amd64
-quad core APU, workstation
-uses a wifi-card

Well, when I run cgminer from a command window I'll get a decent speed of >=3x my average rate.

For my primary miner when I start it it will be at a nice >110Mh/s and then oscillates down to ~34Mh/s.
I've experimented with settings but I can't get it to stay as high as it goes when it launches.

Any help is appreciated.

Check your power saving setting

[$1LK]

OK, check. Still no luck.
I have the latest drivers, too, including the opencl sdk.

[zulover]

which card are you using?

[$1LK]

The wifi-card is a netopia, it's a few years old VID 148F PID 9021.
I think you meant GPU which is a Radeon HD 6530D.

It's clear I can hash at higher rates I just can't figure out how to make it stay that high.

Which AMD APU do you have? My A10-5800k does constant 107 MHash/s without BIOS overclocking, with overclocking it does a constant 113.1 MHash/s and with the new 13.6 Beta 2 driver (which is supposed to give better results to the new Richland APUs) it is giving about 114 MHz (but more unstable, drops sometimes down to 108 MHash/s but also goes up to 120 MHash/s a lot). If you connected a monitor to the APU, then the hashrate drops down with desktop usage (moving mouse, opening programms). So I connected my monitor to my 7950 which isn't affected that much by desktop usage. I''m using BFGminer with Diablo kernel, but it should be very similar to CGminer.

It's an A6 3650, but even when I disconnect the monitor and I remote in it is still at a low rate.

If you got any old graphics card at hand, i would plug that in, connect the monitor to it and see if the hashrate is more constant. Most FM2 motherboards have also a PCI slot, where you could plug in a very old card. You probably would have a problem to find a driver for windows 8 for such old cards and it will then only work in low resolution and with 256 colors, but it's only for testing and if it's a dedicated mining rig then it doesn't even matter.

I actually do have a radeon hd 4350 in the pcie slot, so I'll go try that and see.

try rebooting your comp, mine does that after playing a game or using my comp for awhile, it will throttle down to ~30khash/s from about 300 until I restart it.
nothing a quick reboot won't fix

Is it not possible to have two different catalyst drivers for two different gpu's?

Installing the driver for the better gpu puts the status of the lower gpu into a problem state.
BUT! if I use the driver for the lower gpu I can't mine with the better gpu, or period even since the lower gpu isn't opencl compatible.
And installing one deletes the other; I can't have both.

It's frustrating how asinine the AMD software is.

So, thread closed until I figure out how to get two different radeon drivers installed simultaneously.
