Memory is completely different, and I can't seem to find a general average. Yeah indeed, in the past it was somehow possible but now with these high-end chips it depends from batch to batch and the high performance GDDR3 chips are also going up and down in terms of overclocking potential... So it is just try and see hwo far it will go.

Re:Radeon X1950 PRO, what is the best overclocking program? - 2007/06/19 21:25How about BIOS? I always had NVIDIA and this my first ATI. Damn nice card and overclocking sweet. Can I flash it with whatever BIOS? I think so, bit not certain. And my BIOS does not have a Voltage tab, that's why I want to flash it and have more juice. Where can I measure the GPU voltage on the PCB? And what is the max GPU voltage? Thanks guys for all the help. Keep it up Mavke.

Re:Radeon X1950 PRO, what is the best overclocking program? - 2007/06/20 08:20What about the BIOS? You can flash normally with any BIOS that is for the same type of card. Just keep in mind that ATI cards are a bit more picky if the BIOS will just work fine. I don't know exactly why but that is just how it is... And you can use RaBiT to do some BIOS tweaks. How far the GPU voltage can go, I have no clue cause I didn't play with that...

Re:Radeon X1950 PRO, what is the best overclocking program? - 2007/06/20 17:35If your BIOS doesn't have a voltage tab, that means you have the newer revision PRO, most likely made by Sapphire. You need to do a hardware voltage modification, which is more dangerous and complicated.

Just wondering why you shouldn't try that... Of course then you won't have the latest BIOS...

Because there are two completely different revisions of Sapphire Radeon X1950 PRO's, the older one is reference, the newer one is based on the GT PCB. The GT doesn't have adjustable voltage regulators, and the BIOS's aren't interchangeable. I heard that if you flash the older BIOS to a newer card, you just get an insert the power cord error and it doesn't boot.

Could be but your message does stroke a bit, cause you state you get the insert power card error, but the card doesn't boot? Euh how can you then get that error, cause that is only displayed after booting... Does sound a bit strange to me...

Again, I don't know exactly what happens because I never flashed my PRO to an older BIOS, I never even had an insert power cable error, so I don't even know what they look like. Maybe it does boot, but only enough to get that error, maybe it can be displayed before booting the rest of the computer, I don't know. But all that really matters is that it doesn't work.

Re:Radeon X1950 PRO, what is the best overclocking program? - 2007/06/22 18:33Okay guys, I'm happy whith all the info. But what is it? This is all a litlle confusing. I gues I have to try it, and then we all know for sure. Here is the BIOS from my card, the HIS version. And the BIOS I want to flash, from PowerColor. Let me know what you think.

Well since you just know from others, that is one thing... Although I have flashed in the Radeon X1950 PRO one or two times a diffrent BIOS older and newer and it worked just fine, but not with these newer BIOS's. And you can indeed get this insert power cable but that is, at least in my case once you are in Windows, so nothing at bootup at all. But topic closed as neither of us has actually done it with the newer cards.
