Artifact with Furmark

[oui-oui]

Hi,

I have some artifacts when I use Furmark (or any video benchmark).

My card is a Gainward HD4870 512 Mo Gold Sample.

If someone could explain me where it comes from  and how avoid it



Thanks in advance

The product sheet talks about a "turbo mode", i.e. overclocking.
If that's enabled, try again in normal mode.

750MHz core clock,  DDR5  950 (DDR 3800) MHz memory clock (Normal Mode).
775MHz core clock,  DDR5  1000 (DDR 4000) MHz memory clock (Turbo Mode).

Ill try that.

Thanks

Ha ha ha, no more artefact and double FPS !!

A great Thank you for your help.

For gainward GS users : Just forget the Turbo Mode

well i got rid of my 4870x2 and picked up a evga gtx 285.

when i run furmark at stock clocks i get artifacts within a min of running. temps are about 70-75C. they are small black/white rectangle boxes.

vantage runs fine, wow runs fine but the other night i left F@H on, 100% fan speed and wokeup to a rebooted PC.

think i should RMA it? or is furmark just too demanding and i should brush it off?

Ok, you have an EVGA GTX285. For some reason they run unstable at about 70°C or higher. Seemst to be a general problem with the EVGA Cards. A buddy is using the manual fan control to keep the temperatures down. Some other underclock it.
Do some browsing and try to find aout more.
