Looks good supes your on trak to crush my score ...........

You got a baseline to compare with WD?
I think baselines are invaluable screenys when tuning an os and system for benching. If you find one, please drop in so I can make sure everything is running accordingly ;)

score looks bang on for the clocks Kal.

Thx Rev, updating the rest of the first post and the gauntlet................

yea I hear that unfortunatly I am crunched for time with two boys in premeir soccer.

I usually only have time to toss um in furmark the clocks and run the gauntlt blind post pull out the card and ship it .............

Most of my cards unfortunatly never see their best clocks as I do not have that kind of time ....

LOL my card are typically only 6 benches old when I have to sell them ........LOL

February has been great thought ... I have had a bit of time and trying to make the most of it, as March I am on the road again

here are the rest of my final results sorry I can't be of more assistance

Done with my baseline runs, if anyone see's something out of whack, lemme know.

WD, your runs will be very ver helpful as I start to scale upwards, 4 SURE! ;)

Scores look amazing. Stock you crushed my OCed 550BE and 4850 scores :(

I didn't mean to, HONEST!

Slider on Afterurner and CCC won't do more than 750/1200 and the card doesnt blink at those clocks. Anyone got the solution?

ccc ?

The catalyst control center?

try afterburner, Rivatuner (extend the limits in power user), AMD gpu tool maybe?

This works in 1.4 not sure about 1.5

To unlock unoffical clocks in the Programsfiles/msi afterburner/msiafterburner.cfg
Open with note pad, scroll to the bottom and change unofficial clocks to 1 and it works

Idk if it works with the 4850 but with the 5870 this works.

1. Open Afterburner and set max clocks.
2. Close Afterburner. dont just minimize it, X it out.
3. reopen Afterburner and the sky is the limit.

^indeed a very handy trick

I forgot to mention that you still have to change the cfg file using notepad first like Witchy said.

Yup or BIOS mod it, you can set max voltage that way also.

GPUz to pull BIOS RBE to edit it, and i just used atiwinflash to put it back.
