7900GT OC Limit?

post #1 of 19
Thread Starter 
Currently i have my 7900GT overclocked to 560Mhz/1600Mhz using Artic Silver 5 and Zalman VF900CU-LED Cooler.

Is this considered a good overclock or could i get more from it? Also what utilities would you use to overclock a GPU with tests you can trust?

ATi tool is a great OCing program. I am unsure what brand of card you have and what the standard clocks are for your particular card but there is many including myself that have gone a long way with some of these vid cards. Compared to mine the only difference as standard is you have your core 10 and the memory 100 MHz higher. (I have the 512 Mb version.)



Have you considered doing a volt mod for extra performance if that way inclined?

You OC is respectable, and is similar to some factory OC'd settings (CO , KO).

If you are feeling daring, and you have a steady hand you could attain another 100Mhz on the clock. It requires a volt-mod, and the results will vary depending upon the manufacturer, but more importantly your cooling and airflow through the case.

the ati tool is excellent, your max over clock will be affected by what cooler you have and if you did any volt mods. My 7900gt it at 617/1822, I am using the ATI tool, one of the older Zalman coolers, not the one with the heatpipes, and the 1.4v mod.
