ok guys im so sorry, i got banned for a week.. To speed up a 5600u, just overclock, thats about it. if you get errors with both nvflash and wfflash try wfflash NM bios.rom that might work, but maybe your bios is protected, it says how to deal with protected bios on the first page. Vivo cards do sometimes get problems, i use the leadtek bios and i havent had any problems with, because the bios detects the My Vivo ability. if your having problems with it try another bios, msi or better yet gainward. some people have to flash it a few times with a few different bios's before they find one that fits them just right. Please post your questions again, so i will see them more recently thanks.
