I need more beta testers. I implemented extended voltage control options I need tested. There are several groups of testers I need: 4770/5770 users I implemented L6788A voltage controller chip support (thanks to LKJask). Many 4770s and 5770s utilize this chip. So if you have a 4770 or a 5770 you wish to volt mod, give it a try. 4890 users As 4890s use a VT1165 to control memory voltage, I implemented memory voltage modding capability for this card. Please try it out. 5850/5870/5970 users GPU and RAM voltage modding should be available now. Please test it in detail. Please note: This software is beta. You use it more than ever at your own risk! Again, this software is beta. I need your test results. Please do not just use, be pleased if it works and remain quiet. Communicate! Thanks. If you have overdrive enabled, please be sure to disable it before flashing any RBE modded BIOS. Download the beta version here.
