the 380W earth watts should be more than enough.
try putting it all back to default clock, restart, and mine again.
it gets only worse on stock clock
When I first put it in it worked just fine. I was doing some stuff on my hard drive (moving some files) for a while, went to watch a movie in the other room while I was mining.
I came back about an hour later and I had artifacts all over. There's less of them when I underclock my vram to 275, but when I start mining there's more of them.
I have a very modest setup:
E8400 dual core CPU, one hard drive, four usb devices, one disk drive and the 5850 card, and one case fan.
Is my two-year-old 380W earthwatts PSU enough to handle it? According to online calculators I should be fine unless the capacitors on my PSU have aged. I'll test my card in another computer later just to make sure.
Is there anything else that can be causing it?
you mean your memory clock is at 275? try increasing to 300ish... or take your core clock / 3 add about 14 and use this for mem. clock speed
doesn't solve artifacts, hashes slower on stock and worksize=256
275 is faster than 250 and 300
