shiecldk Posted October 14, 2013 Share Posted October 14, 2013 Firstly, we need to know our GPU clock. For example, my ASUS EAH6850 is running at 790MHz. Secondly, convert 79000 to hex, which is 0x13498. While in the vbios, it's actually 98 34 01. If I want to get a 850MHz clock, I gonna convert 85000 to hex, which is 0x14C08 and 08 4c 01 in vbios. Last, use Clover's PatchVBiosBytes to find 98 34 01 and replace it with 08 4c 01. And all done! Unfortunately, I'm not able to boot my current Windows 8 with Clover now. But I'm guessing simply reinstall graphic driver or Windows could bypass the problem. Because I'm able to boot Windows Install DVD through Clover. These are the results to prove it works : Before After Before After Before After Before After 6 Link to comment Share on other sites More sharing options...
ScarletCrimson Posted October 15, 2013 Share Posted October 15, 2013 Thanks for the guide. Here's how to use PatchVBiosBytes: http://clover-wiki.zetam.org/Configuration/Graphics#Inject-/-ATI Also, can you please copy and paste the data from your config.plist file here?

Alex009988 Posted December 12, 2013 Share Posted December 12, 2013 Hi, shiecldk. And what about memory clock. Should I do the same action? Link to comment Share on other sites More sharing options...
shiecldk Posted December 12, 2013 Author Share Posted December 12, 2013 Hi, shiecldk. And what about memory clock. Should I do the same action? I'm not sure about memory clock now, but I did tried to OC the memory clock too. What I did was using RBE to edit my VBios first and compared the difference with original VBios in HexEdit. And last, input the PatchVBiosBytes value to Clover. My 6850's normal memory clock is 1000(mhz)x4 which is something like 0x186a0 and "a0 86 01" in VBios if I remember it correctly. After using RBE to increase the VBios's memory clock to 1100, "a0 86 01" become "b0 ad 01" in Vbios. 1 Link to comment Share on other sites More sharing options...

Could you help me to change memory clock from 800 to 928MHz at this place? I also attached almost-modified Vbios. EDIT1 Wait a minute! I have to check something. 2D - 200, 200, 0.9 3D - 300, 300, 0.9.rom.zip Link to comment Share on other sites More sharing options...
Alex009988 Posted December 13, 2013 Share Posted December 13, 2013 Ok. Made an overclocking with new frequencies by DSDT. I see some artifacts on Ungine Valley. So I decided to use default frequencies on Mac Because I have no graphics-demanding programs on Mac unlike Windows. Link to comment Share on other sites More sharing options...
