Overclocking AMD Sapphire 7850HD OC [Help Request]

post #1 of 3
Thread Starter 
Hello everybody,

I have a question about overcloking my AMD Sapphire 7850HD OC. As you can see from the title the card is OC version and it has 2gb memory, 256 Bit and Gddr5. It's a great card. So far it has shown me great results and I'm glad that I purchased it. Now to the overclocking matter. By using Trixx or Afterburner I am able to overclock it (Gpu clock 920 to 1050 and memory 1250 to 1450). The thing is whenever I go beyond 1050 for gpu clock and 1450 for memory clock it goes unstable and crashes my pc forcing me to restart. I wonder if it is possible to overclock it to higher rates or if it's a no go. Thank you in advance...

P.S. I used to overclock my card using MSI Afterburner but I noticed that whenever I overclock it the screen goes jumpy and it becomes unstable, I recently tried Trixx and it worked like a charm, it goes all smooth with the same overclock setting I applied with Afterburner. I've read many threads about this and It seems everyone is suggesting Afterburner over Trixx because of the extra features but I had no luck with Afterburner so far.

Use Trixx to up the voltage to 1.3 and try again.

Generally, you push the card clock until it is unstable, then you up the voltage and continue pushing the clock. You can do this until you reach a comfortable voltage or the card just won't go any faster.

I don't know if this card is hard voltage locked though, I know many AMD cards are.
