*** Official OMG I've finally got my 5850 thread **

Mine too hits 1ghz with 1.25v :D Max core temp is 41C :cool:

Crysis 1080p/high/4xAA/dx9 - 51avg/28min/60max

I've found though that GPU clock tool is causing the vcore to randomly go to max (whatever that is) and causing the VDDC temps to go way too high. If I can keep it at 1.25v then it's no problem and I think 1ghz could be a 24/7 overclock. Roll on modded bios' and full afterburner support.

No, it's definitely pushing the voltage up to max(probably only to 1.35v as fornowagain says). VDDC temps go really high under load when this happens.

I've just discovered that if you close GPU clock tool, after setting the clock, the voltage remains at 1.25v and the clock stays set
 
In afterburner and GPU clock tool. As Fornowagain says, it shouldn't be actually going over 1.35ish.

If I close GPU clock tool after setting the clock then it doesn't happen.
 
The voltage increase in afterburner definitely works because we are getting 1ghz core and the benchmarks prove it.

I totally believe the VDDC temps in gpu tool and that when it goes to 1.6v it goes to whatever the max voltage the hardware will allow.

Yeah it makes a big difference to the overall score...........show off!! :rolleyes::D

I reckon you'll probably be able to get that core up to 1ghz with a full cover block on. I'm going to have to get one I suppose, unless that little VRM heatsink that someone posted earlier works really well.

That looks like, at some point it's seen a spike of voltage through the sensor as I'm guessing it's range is 0-255c. I've had one show max 255c a couple of times.

\o/ my saphire 5850 installed and playing and I am pleased to report I can actually tell the differance between this and my previous 4870 512.

Just got to make the effort to install windows 7 on the new crucial SSD now.

Nice one. Enjoy! :)

Anyone tied that driver dated 13/10 yet?
