Scanning for artifacts when overclocking GTX 470

[Michaeljcox24]

Just fitted a VF3000F, and overclocked my card to 850.

Temp stays around 70 on furmark @ 1.05 volts. I can't see any funky dots or lines appearing, but when I run ATI tool, I keep getting errors (yellow dots)

Is this software trustworthy, or do the majority of people just judge an overclock stability on if furmark / vantage runs without crashing for 15 mins or so?

Or am I being completely stupid in running an ATI program on an Nvidia card?

More info - @ 850 after 10 mins the card clocks itself down to 400MHz for some reason, don't understand because temp doesn't go above 70C

MSI Afterburner. I'm running furmark in one window and watching the graphs in the other.

I don't understand how it wouldn't think 99% usage running furmark is insignificant load.

Ok, I'll try tropic demo, see what that does.

 

[Michaeljcox24]

Just ran tropics for 45 mins, like you said, 850 core, 1.087v, no crashes or artifacts.

Ran heaven benchmark, there was only 40pts between 800 and 850mhz overclocks, hardly worth coughing about really.

P.S Skyrocket, you 'had' a 580? What have you upgraded to in the space of two weeks lol?

After todays shinnanigans I'm tempted to get a 580

I think ur CPU is holding u slightly back.
Yes I had a 580 gtx played with it for 5 days and returned it. Now I have Msi twin frorz II 470 in SLI which cost me 360£ and spank 900-2350mhz 580gtx for less money and less noise.
Still playing with final clocks but at 800mhz it butchers the 580 aka 485 gtx.

Yes, unfortunately I'm stuck with socket 775 for the time being, board is only 5 months old as it was an emergency replacement of an old P5N-32 series that packed up on me one day in the summer.

I've been looking on a certain auction website and I'm particulary interested in either a Q9550 or a QX9650, I'm told both could overclock a lot more than my current B3 Q6600. Can't afford an I7 full bundle so I'm going to stick with 775 till the enthusiast class sandy bridge come out next autumn.
