Thanks epitaph i entered that line in xterminal and it accepted it but nothing happened , is that correct? Or should I have seen something occur. My max and min are fixed at 850 for the time being so I will wait and see if it reverts back to 125 as a min. Hopefully this works and it stays fixed at 850. Thanks once more for your response. Also is the xlv profile the optimal profile to fix an oc too? It's the one Jakiman uses but I don't know if that's personal preference or what is recommended
