donotspamme Posted August 9, 2013 Share Posted August 9, 2013 HiI am new to this forum but not completely new to flashing.My probem is I flashed a (by myself) modified vBios on my 6990m in my P150hm (Subvendor is Dimotion) but it doesn't have any effect.I read it out with atiflash in dos, then modified it with radeon bios editor and flashed it agaoin with atiflash in dos. without any errors.I wanted to undervolt it to 1.0 Volt at 715/900 but it still runs at 1.1V (overdrive is deactivated)I also tried to overclock it to 730/930 with 1.1 Volt just to see if it works but unfortunately it does not!Gpu-Z shows me the raised clocks but it always stays at the standards even in games(715/900)Has anybody an idea what I am doing wrong?Bios is the latest downloaded from the schenker homepage (EC13 and Bios14 I think)If anybody needs more info please leave a replyThanks in advance!

donotspamme Posted August 10, 2013 Author Share Posted August 10, 2013 Thx again! I will try your version! Have you changed the values with Radeon bios editor or another program or directly with hex-editor? greetzThx for your help but it still runs on 1.1 Volt. Has anybody else an idea why i can't undervolt or overclock my card via bios? Quote Link to comment Share on other sites More sharing options...

Has anybody else an idea why i can't undervolt or overclock my card via bios?I use Free Neo Hex Editor.I can try changy some voltage values, but I'm not sure it's safe. If the replacement of certain values does not help, then you need to change the adjacent values 1 Quote Link to comment Share on other sites More sharing options...
donotspamme Posted August 11, 2013 Author Share Posted August 11, 2013 What are the " adjacent values"? Quote Link to comment Share on other sites More sharing options...
Aikei Posted August 11, 2013 Share Posted August 11, 2013 What are the " adjacent values"? Sorry for my english (i am from Russia) ajacent values it is same voltage values in vbios, identical voltage values are arranged adjacent to each other. For exaple (in your vbios): 1 Quote Link to comment Share on other sites More sharing options...
donotspamme Posted August 11, 2013 Author Share Posted August 11, 2013 OK I think you are deeper inside that than me but i don't understand why it works at other people without any problem and not at my card Quote Link to comment Share on other sites More sharing options...
donotspamme Posted August 12, 2013 Author Share Posted August 12, 2013 First of all thanks for your help Aikei but I solved the problem by myself! It was the driver! With 13.8beta it did not work but with 13.4 stable it does! Undervolting and overclocking works fine Thread can be closed! Quote Link to comment Share on other sites More sharing options...
