I heard something about passive cooling is that any good? m 0 l the last resort February 26, 2010 1:13:55 AM well, if you buy an Arctic Cooling Accelero S1 and attach a 120mm fan you can overclock pretty dang far. My 4850 is sitting at 700 core, 1133 mem. Max temps dont exceed 47C. Linky: http://www.newegg.com/Product/Product.aspx?Item=N82E168... also very quiet. m 0 l pakardbell486dx2 February 26, 2010 1:15:49 AM with those speeds, do you see any significant improvements in frame rates? m 0 l Best solution the last resort February 26, 2010 1:38:10 AM ok. my monitor is at 1920x1080. I am testing with Furmark 1.8. The MSAA is at 4x, and ran for 30s. OCd: 875 pts. Stock:777 pts. so, i guess a 12.6% improvement. (875-777) = 98, and then 98/777 = 12.6 when the MSAA was increased to 8x, scores were identical. Max temps after those 30s was about 40C.
