48xx voltage increase w/out mod?

post #1 of 12
Thread Starter 
Has anyone played with the profile voltage settings to see what if any increase you can get out of it?

I noticed when setting my fan speed by editing the .xml (profile) file, that there are settings for volts... Anyone used that yet? Any guides to using it?

I have messed around with the entire profile, changing min/max clocks or core and mem, fan speed, volts, etc. But out of the range provided yields no results. I guess I'll just wait for RivaTuner to release an update.

The max through BIOS/CCC on the 4850 is ~1.2V I believe (so if you put e.g. 1.4v in, you'll still only get ~1.2v). The VisionTek cards actually use a lower voltage, so you should see some benefit. There was a guide at XS, but they're down for upgrades right now. You can also just use RBE to mod your bios and flash using atiflash/winflash.

still 1.2 volts should be beneficial to overclocking. no...

XS is back up, here's the relevant thread. Apparently only certain values work in the profile. And yes, 1.2v is quite beneficial .

+rep for the link

Thanks... I am lucky I guess my visiontek hits 700/1100 without editing the voltage. Which means that once RivaTuner or ATITool gets updated I might get to push this card higher and just change the software voltage settings. Nice I was really hoping to push the ram on the card faster...

Hmmm...

If I push the general voltage higher will I be able to push my ram higher??? I must now play THANKS!

The voltage affects the core. For memory, you need to mod the card (pencil/volt). Most say it is not worth it to increase the volts to the memory since they are quite sensitive and the gain in performance isn't that significant (compared to a Core OC).

What's the point if you have a 4870? I was able to easily max out the allowed CCC overclock. Riva NEEDS to put out an update, like yesterday!

The point?? When RivaTuner or ATI Tool does update, I want to know how I am going to get the max OC that I can... (without any mods or bios flashes). Lifetime replacement if I don't mod my card... Gotta love VisionTek!
