Hi, I read this article :http://forums.techpowerup.com/showth...242#post528242 I'm trying to flash my bios so I can get (max)1.3v and overclock it! So I set my Exact Mode volts to 1.3 already all of them. Then I went to VID as you can see in photo, and made them all 1.3v Then I saved it (already did the 1st step of entering all my clock values in clockrates tab). Then I closed and re loaded it just to check and look : In Exact Mode volts they are all 1.3 as I set them but in VID it all turned into 1.2 and all the other options are ???v for all 3 of the volts and options... Well I tried with this option anyway and it worked But in WIndows XP Sp3 and Atitool I get this : Some error message? When I put my cursor over the warning sign it says : "Core frequency 0.00Mhz is outside clock safety range." But with GPU-z All my cores are the same as original. What is going ? So as the article suggest I got the RiverTuner 2.22 and installed it. But before using it I tried a new setting with Nibitor. Everything is the same even Exact Mode Vs, all to 1.3v. Except I didn't touch VID Mode. So it is Voltage 3 : 1.2v 2 - 1.2v Voltage 2 : 1.3v 1 - 1.3v Voltage 1 : 1.1v 0 - 1.1v These are default and current settings as changing it to 1.3v didn't work as I showed the previous photos. Well then I tried overclocking : (sorry image is bit stretchy don't know why!) Anyways If you look at Riva Tuner 864 / 1855 / 1100 clocks right? But if you look at other 2 tools : EVGA Precision and ATitool they are both at 540 / 1450 / 900 only... But strangely this time in GPU-Z it is 864 / 1855 / 1100.... I'm so confused Maybe because my VID setting.. I don't know.. I've tried artifacts scan on atitool but nothing for so long... Just in case I did a 3dmark testing on default setting and in CPU testing my screen goes crazy in color til the end and it finished. I get a lower score ~ So I guess it didn't work.. So I Set with Rivatuner, like I raised core clock to 770 from 675. Then closed. Opened GPUZ and got 770 but on Sensors tab it was 0mhz and when I put cursor over @0mhz. Waited some time and it turned to 770. But after a while it suddenly went down to 675 @675. But in Graphic Cards tab it still says 770mhz in current clocks.... Also in EVGA precision in the sensor graph, its 675 but on the controlling thing it is set at 770mhz. Atitool still has the warning sign and it says current clock is 657 too... What do I do, it's not overclocking~ Also If you look it is I think usually at my default 675/ 1008 / 1450 but when I overclock it in this case 760 / 1072 / 1632, it goes up then it goes down to 540 / 900 / 1450 for some reason then goes up and down constantly and with 3dmark I keep getting worse result then before... and I heard that there is a way to change the volt for my vga with RivaTuner... Anybody know how?
