Re:What about the Radeon X1950 PRO, and BIOS modding? - 2007/06/10 11:00Well I checked the BIOS and it seems that the voltage editing is not feasible as it is not present in the BIOS, so if it is not present than RaBiT will not be able to change or let you edit something that isn't there...

Re:What about the Radeon X1950 PRO, and BIOS modding? - 2007/06/11 03:14That's what I though. It has non changeable voltage regulators, that sucks... So no voltage changes just overclocking...

Re:What about the Radeon X1950 PRO, and BIOS modding? - 2007/06/14 21:12I seriously doubt it, it has the same voltage regulators as the GeForce 7 series, and none of those are BIOS adjustable. But not all is lost, I found a Russian site explaining how to pencil modify a Radeon X1950 GT, which uses the same PCB as the PRO in question.

On some of the GeForce 7 series you could change the voltage from the BIOS, like on the GeForce 7950 GT... And you can't compare the GeForce cards with the Radeon cards. They work maybe with similar voltage regulators but the logic behind in what is possible via the BIOS is completely different.

I didn't know that, I was mainly talking about the GeForce 7600 and GeForce 7900 series. But that's not really important.

Secondly on some GeForce 7600 card you could as well play with the voltage from the BIOS, don't know if it was the GS or GT, but on one of them it worked as well just fine. So really don't start comparing ATI with NVIDIA on that point, they both handle the voltage regulation quite differently.

Re:What about the Radeon X1950 PRO, and BIOS modding? - 2007/06/19 23:15Anyways back on topic, I may have found a bug with RaBit with the X1950 PRO. It seems that the "Realtime" checkbox in the memory timings tab does nothing, I loaded my BIOS using "Open-->OnBoard EEPROM" and the "Realtime" checkbox in the Memory tab isn't checked, but it still allows the driver to change timings, maybe I'm understanding something wrong and I don't know what that checkbox really does, but I'm fairly sure it's a bug.
Also, my reference 7600GT didn't allow BIOS voltage changes, it must've been some non-reference designs that could do that. I know for sure that the reference 7600GT and 7900GT didn't allow it.
