Can someone tell me if this is a good overclock?

GPU CLOCK: 1050
GPU VOLTAGE (mV): 800
MEMORY CLOCK (MHz): 6224

I'm suprised how low I managed to get the voltage, is this normal?

Thanks in advance,

It's not a good OC, but it's a good speed taking you've undervolted the card substantially.

Most 7850's will do 1050 fine on stock volts, and usually go to around 1100 on stock. With a volt bump they all do 1150 core, and good ones do 1200+.
 
If I up the voltage, what settings would you recommend I try?

I just used a different benchmark and it failed, so I will leave the voltage at stock....
 
Managed to set the following but the fan was working hard...

GPU CLOCK: 1150
GPU VOLTAGE: 1155
MEMORY CLOCK: 5800

RESULTS:

Powered by Unigine Engine
Heaven Benchmark v3.0 Basic

FPS: 94.4

Scores: 2377
Min FPS: 42.3
Max FPS: 176.4
 
Much better :) Most folks try and keep the voltage under 1.2V. So you're fine with that clock.
 
Im hopefully getting another of these cards, will crossfire make a lot of difference in games?

Some say it doesn't others say it does... Also, is it true that the more cards you add in crossfire the worse it performs?

Also, the guide in my Mainboard for Crossfire says use 2 bridges but my card only has a socket for one bridge :s is this right because it would make it impossible for me to add more than 2 cards?

Thanks for your help mate...
