XFX HD 6850 Black Edition reviewed - 5. Overclocking

Written by Sanjin Rados

Review: The fastest factory overclocked HD 6850 yet


Overclocking

Overclocking the card to 940MHz increased the GPU temperature to 70°C with our gaming results increasing up to 11%. Bear in mind that each sample overclocks differently, so you might get equal, higher or lower scores depending on the card. We managed a 110MHz overclock for the GPU without meddling with voltages, because while this card supports software voltage regulation - current tools don’t feature support for that.

Consumption


XFX HD 6850 Black Edition is powered via one power connector. Reference HD 6850 consumes up to 127W (19W in idle) whereas Black Edition will naturally need more.

I think I would save the 20 bucks and move the slider over to 820/1100 myself.

As I always say: You can't overclock ATI/AMD. 2 to 5%, that's it.

Overclocking my GTX460 by 25% was no problem.

An overclock from 775 to 900-920 on standard volts, its no overclock-able? and with volts+ it might get 950-1000 - that is 20-25% if you are bad in maths

Actually I'm impressed by the cooler on this card, does the job way better than reference design. What a nice card :)

Who's talking about "900-920"? Maybe in an ATI fanboys dream?

Read the article:
Reference clock 6850 : 775MHz
XFX HD 6850 Black Edition : 820MHz

That's not even 6%.

Did you read the article? They overclocked it to 940 MHz on standard voldage, 820 is what it was overclocked at from the factory. You said you overclocked your card 25%, not that it came factory overclocked 25%. 775 to 940 is a 21.3% overclock on the first batch of 6850's, without increasing voltages, which isn't too shabby.

Even that measly factory overclock is more than 5%. But as more companies come out with their overclocked boards, look for more and more. Remember, this card hasn't even been out a week, and most of the first boards were clocked at stock speeds.

Nice looking cooler. The Black Edition is a great card, but it's not OC'ed far enough IMO to justify the extra price. You can easily OC it yourself. But that cooler may keep the card much cooler than stock.
