I bought a MSI R7770-PMD1GD5. I'm having trouble overclocking it, I want to get the best performance(FPS) W/O upping the voltage. My current overclock is @ core 1060/mem 1300. I'm using the MSI overclocking utility.

Best solution

With out the power/ voltage increase your overclock mileage will be very short. Every Card/chip is differnet some clocks better others dont. Use MSI afterburner and increase 25mhz core clock and then another 25MHz. Memory 50MHz than another 50MHz so you will know your limit. Each time Play very high quality games for few hours see if it last. Run Vantage/ 3dmark etc. If fails give the power target voltage a little bump see what chane it brings ( if the volt / power slider goes to full doesnt mean all card can use that. ) This should give a better understanding of your particular cards overclocking capability. Heres one example/review http://www.guru3d.com/articles_pages/msi_radeon_hd_7770... No overclock is always 100% stable though. Thanks

I can't bump up the voltage on the card. I guess I hit the limit.
