^ yeh because oh heat + stability etc, but I think he means the OC programs or CCC won't let yu put the slider past 1000Mhz
I´m sitting at 1000/1200, cpu at 3600, and i get 11880 for gpu on Vantage... Now, i want to break that 12000 barrier for me, so, please please give a hand on getting that another bios for this card if that is what i need to get to break 1000 core... I just need those 20-50mhz more core speed to get that 12000 >< Memory is running pretty much at the limits amt and if i´m not totally wrong, memory is running at 1.2375v, as i believe thats the memory voltage, atleast it helped abit when i increased it, to get memory to 1200. Now, you gurus and pros, help meh to get that 12000 gpu vantage points.
Yes, it can, but when i slide it to for example 1050, apply it, it goes back to 1000mhz. Edit: I got my hands on Sapphires Atomic cards bios. How much does basic 4890 difference from Atomic model other than Atomic has higher clocks?
You should be able to use Rivatuner to go above 1000Mhz. I've a XFX Black Edition as one of my two cards and it will go to 1045Mhz (the will only do 900Mhz). In Rivatuner the highest I can set either of my cards is 1305 (not that either will do anywhere near that!) as opposed to the 1000 in Catalyst Control Panel (even on the BE). Afterburner does not work with either card.
Yeh, used gputool to get past 1000mhz, but it drasticly went so unstable after that, i did one vantage run at 1020mhz and it seemed that it was so close of tossing a black screen, volts were at 1.4v. I´ll leave this experiment later, when i´m intending to buy new card, can´t afford to fry the card yet ;p
Who knows the one bios can I get to raise to more than 915... I got a Powercolor HD4890... and MSI Afterburner dont rise voltage... any trick?
you don't have to change the bios at all really. you simply use msi afterburner for the voltage tweak and use amd gpu clock to overclock it as far as you want. i use those 2 all the time and work well. take in mind using those software to override the CCC panel clocks will cause your clocks to run at consent speed and won't downclock itself,so if your worried bout your card temps you can simply down clock it your self to save power and run cooler.i do that with my 5870
i just intall the latest version 1.41 and try... and nothing works.. disabled voltagem modification...
http://forums.guru3d.com/showpost.php?p=3376459&postcount=5 Thats from another thread from me, the trick to get past my "lock" worked for me, in Afterburner. Voltages are still capped 1.35v, but when i next time start to oc this card, i have gputool for raising the volts.
If you're interested in breaking the 1.35V limit, you can use this program: http://www.xtremesystems.org/forums/showthread.php?t=227628 It allows > 1.35V. To use in conjunction with MSI Afterburner, simply set your clocks in Afterburner, and then set the voltage in the Voltage Tuner program. Simple as that. Repeat if you are changing the clock again.
