Hey guys. I've tried to upgrade my a4-3300m processor to a8-3520m, but when i put this processor, nothing happens (i see only black screen, nothing more). I have 214 bios version.

 

Is it a known working processor?

 

Yes. I've bought it a few days ago on ebay for $15. The seller said that processor is working properly.

 

I don't see a problem of using it on the system due to identical architecture and TDP wattage, so without being able to verify the processor you got it's hard to confirm.
