From my log file: 2004-11-15 06:40:25 Artifacts detected after 35:10.07. 1 pixels don't match. 2004-11-15 06:40:25 Clocks set to: 411.23 / 394.62 2004-11-15 08:08:00 Artifacts detected after 87:34.61. 1 pixels don't match. 2004-11-15 08:08:00 Clocks set to: 411.75 / 393.75 2004-11-15 08:42:35 Artifacts detected after 34:35.37. 1 pixels don't match. 2004-11-15 08:42:35 Clocks set to: 411.75 / 393.19 2004-11-15 10:11:02 Artifacts detected after 88:26.50. 1 pixels don't match. 2004-11-15 10:11:02 Clocks set to: 411.00 / 393.00 2004-11-15 11:03:38 Artifacts detected after 52:36.19. 1 pixels don't match. 2004-11-15 11:03:38 Clocks set to: 411.23 / 392.54 2004-11-15 11:46:52 Artifacts detected after 43:13.92. 1 pixels don't match. 2004-11-15 11:46:52 Clocks set to: 411.75 / 391.50 2004-11-15 12:38:06 Artifacts detected after 51:13.48. 1 pixels don't match. 2004-11-15 12:38:06 Clocks set to: 411.23 / 390.46 2004-11-15 14:46:33 Artifacts detected after 128:27.22. 1 pixels don't match. 2004-11-15 14:46:33 Clocks set to: 411.75 / 389.81 It's like this all the way up to 398MHz memory. I'm thinking, you know, 1 pixel not matching every hour or even two hours isn't that bad, because this error continues from 398MHz all the way down to 375MHz, so I wouldn't mind having an extra 24MHz memory clock if it was just one pixel now and then being screwy. I wanted to ask if this would have any adverse effects? I mean, when I had my 9500, if my memory was too overclocked (it would only go to 300MHz, and then 301MHz caused artifacts) everything would go all screwy, polygons would get messed up, lots of not nice things. Now, I've been playing CS Source for a while at 395 and it seems alright, is this "1 pixel" that doesn't match just going to be a slight error here and there or do you feel that it could (eventually) lead to a massive amount of data corruption by some sort of snowballing or domino effect? Should I try the old artifact scanning method to see if it even picks up the one pixel? So, to summarize, if I leave artifact scanner on for a good 12 hours or more, and I only ever get "1 pixel doesn't match" do you think it's safe to leave it o/ced that high?
