X1950pro oddity

post #1 of 7
Thread Starter 
As most owners of this card have discovered it doesn't OC well and there is little support for OCing it with the usual stuff.

In fact after I OCed it a bit with ATT I was getting lower and lower scores...

Now I have followed the advice in some of threads about OCing this card and none of it worked.

Can anyone show me how they managed to get any performance beyond stock?

Whatever I try seems to make things slower and less stable...

Thanks in advance...

From what you are saying overclocking makes it perform worse...have you tried underclocking?

The mem is slightly UCed for some reason. I guess i could. Running any tuning tools eventually leads to a corrupt OS. I have had to reinstall once already...

Then just leave it? It already is a nice card, don't need to kill it.

I had this problem as well. You just have to OC using this directions. Only OCing the memory will lead to lower benchmark speeds, and only if it is done incorrectly. Read this little guide:
http://www.overclock.net/ati-drivers...irections.html
I use ATI Tray Tools latest Beta version to OC the core. While keeping ATI Tray Tools in the tray, then open Rivatuner (I used 16.2, but final may work, not exactly the same as I described there) and set the memory clocks according to your clock stepping as described in my little guide. Mine stepping is 27 MHz for the memory. I have my card set to 661 MHz core, 823 MHz memory. This is completely rock solid stable. I also have read that increasing the PCI-E bus speed will allow for some more OCing on the core, but I haven't tried this just yet (out of town now)
Also, if you can't get Rivatuner final to work, when I get back in town I'll create a torrent for you or something and I'll upload it.

Overdrive doesn't work correctly, for the memory at least. When I used overdrive with the Sapphire X1950 Pro that I returned, I had lower 3dmark scores than with the stock memory clocks. Now that I have the HIS model, it doesn't support Overdrive, probably for this reason. They used the BIOS to overclock the card out of the box to 620 core, 740 memory. I reached 661 core and 823 memory.
