Hello, I have now 16 active pipes on my X850PRO AGP. After flashing with the XTPE rom I restored the original X850PRO rom to avoid the extra heat from the XTPE frequencies and maintain fan control. I gained around 15-20% in performance running at stock 500/500, very nice trick, thanks a lot to all the posters for sharing about this hack. What else can I do now with stock video card cooling and a well ventilated case ? My temps. are around 72C at full load at 500/500, can I safely up the numbers a little bit and gain some more speed ? what numbers do you recommend ? Thanks ! Camilo.
