I recently bought a HD5770, i'm very happy about it and it performs well.
But I believe my CPU is bottlenecking the card, so I want to overclock my E5200 @2.5Ghz to 3Ghz or maybe even 3.2Ghz.
Can someone explain step by step how I should do it, like the settings of the FSB and multiplier, and if it would be safe on my computer.
Kinda new at this I never overclocked before.
I have a Corsair 450W.
The stock cooler on the E5200.

Next stop should be a guide for your particular motherboard. Google is your friend.
Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 200 MHz, your memory clock should be at 400 MHz.
Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.
