ATI Hd 7950/7970 bios mod thread - Page 73

Any just compare them to stock bios, see which one works best. Games, programs, benchmarks, folding, or mining. I know there is a small gain in games and benches but I don't mine or fold so I don't know what the results would be.

For my own cards that is, what is posted above is Lards improvements, at the same clocks just edited bios ram timings and other bios tweaks.


Could I get some help? smile.gif

I only do gaming, no mining or anything else.

The pic below is the GPGPU Bench. 1505 is what I still have loaded. Tried clocking 1505 to 1140/1600 locked up after 10 min. Haven't tried overclocking on 1500 yet. Just from the bench it seems my times weren't too off from what you changed. The difference is so small you could almost nullify that due to error margin. What was different between 1500 and 1505?

1505 is slightly tighter then 1500, They are both set to work best for 1500mhz i will rework them tommarrow after work As well do some for ColdBlackIce. Like i said before its a small gain for the same clocks. Each ram strap has a set of ram timings, finding which one which works best for your own card just takes a little time, its not a massive just the same as your own cpu running the same frequency with slightly better timings. Too tight and it freezes, Some would require slightly more voltage to run the same frequency with tighter timings just as regular ram for the cpu.

At no change just re-flash the 1510 showed slight improvement overall. The 1515 showed no change overall. Ill OC on 1510 and post results.

Pulling 760KH/s on 1510 @ 1140/1600 100% stable with awesome temps on air alone @ 1.213v +10% Power

Any higher on either at stock voltage results in momentary driver lock up. then a required restart to fully re-enable the driver.

What KH/s did you pull before on stock bios?

570 - 600 KH/s also ran into a snag at about 45 min mark she locked up so running 1065 / 1600 just fine but only pulling 670KH/s. If I bump the voltage I may be able to stabilize it well see.

What were your stable clocks before? Was it the same or similar? Was it running higher clocks and was it pulling the 570-600KH/s? Looking for clock to same clock to see what the increase would be. Also looking to see what a comparable clock would be from stock to nodded bios for the same KH/s.
