Yeah, I got sick of the 900/1300 limit. Afterburner works fine now.

So to understand you correctly, you have your normal Sapphire bios with ccc capped at 900/1300 and AfterBurner is pushing it passed that limit to 1Ghz? If so, I didn’t know that. I thought people had to get the ASUS bios to up the ccc, thus upping what Afterburner could see.

Unfortunately not. Afterburner seems to be forced to the same limits as CCC, hence why I flashed it with the uncapped Asus bios.

Gotcha. what I though. Thanks so much for the info.

Now if we can find a ASUS 5850 bios to go around, that would be great. Someone hurry up and buy one.

Wow, Lyall. I could only get 1GHz stable at about 1.35v and you got it at 1.2?

Later tonight I'll get more pics up for you, snow cakes.

Yeah, would be interesting to see how far it would clock at 1.35v . I remember reading on XS that the default voltage seems to vary over 5870s. For example mine and a couple of others default at 1.12v where as some default at 1.16v. Some review sites are saying that its basically a VID for the GPU Core.

Lightman : Going back to card loudness I've noticed that some models are using 1.125V for GPU under load (like mine Sapphire) and other are using 1.165V under load. This might explain quite big variations between different reviews in power consumption tests under load...

Dave Baumann : Actually, it does the opposite! We scale the voltage based on leakage, so the higher leakage parts use lower voltage and the lower leakage parts use a higher voltage - what this is does narrow the entire TDP range of the product. Everything is qualified at worst case anyway; all the TDP calcs and the fan settings are completed on the worse case for the product range.

Good news for the 5870
157/300 .95v idle
400/900 .95v/1.063 blu-ray, UVD
400/1200 1.063v 2d multi-display eyefinity
600/900 1.063v OVP/OCP initiate throttle
850/1200 1.162v 3d performance

And, loco just did 1200mhz core / 1250mhz mem on Tri-Fire using 1.375v thru afterburner (LN2 cooled). He says that > 1.375v doesn't give him any higher mhz, so he thinks that OCP must exist somewhere around 1.375v.
ATI Radeon HD 5800 Series Graphics Cards - Designed by the Community

Quote:
With the ATI Radeon HD 5800 series we’ve implemented a hardware-level overvolt protection scheme where a signal from the regulators can be fed into the GPU directly and the GPU can take action if the regulators indicate they are operating out of their specification. In the unlikely event that such a scenario happens, rather than the board turning off, the GPU is designed to clock down to get the regulators back into a normal operating zone and then clock back up when they have done so.
update: link fixed.
