my 5830's driver keeps crashing

[ranzolu]

hey there,
I'm mining with with an Ati Radeon HD 5830 (core clock 965MHz, memory clock 300MHz, VECTORS AGGRESSION=8), with a PSU of 420W. My problem is that if press ALT+TAB when I am mining and I want to switch from *someprogram* to Excel the ati driver crashes. Anyone noticed athis strange behavior?

I'm looking forward for your answers, thanks.

EDIT: it happens almost every time i press alt+tab

To be honest, this doesn't surprise me at all. There are a couple issues:

1. You've got your core clock pushed to the max, assuming you're on stock voltage. I run my 5830's at 960Mhz.

2. You're running on a minimally suitable power supply. I would want at least 500W for a single 5830. My 4x5830 uses a 1200W PSU.

3. Excel 2010 uses DirectX for rendering. If you're miner is putting your GPU at a 99% load, I would expect the driver to crash if you attempt any sort of rendering.

To add onto what he is saying turn the pretty off. Turn aero off or what ever makes it look aesthetically pleasing.

yea, I turned off my AERO
Running a 5830 and a 6970 (both overclocked) on a 500W PS and it's been running fine for weeks.

I use excel 2010 all the time.  No crashes.

Ignore this. I run 4x 5830s on 700 watts for over a month on multiple machines just fine. The system uses only 550 watts, so it's well within limits.

lol my rig is even worse but it doesnt crash with ~285 mash on a 300W power supply 875 core clock

how do i turn off the semitransparent windows 7 thing??
