I need a general advise on what chipset (or even motherboard) is preferred to use with -rt patch to get rid of latencies. Now I use ICH6 based ASUS motherboard and have ~60us latencies in worst case while running `cyclictest -n -p 99 -t1`. And that's not good for my application. I also tried to run this test on EliteGroup SIS 761GX chipset based motherboard and got ~13us for the worst case with the same test. So can anyone provide some usefull info on which chipset to choose? Or should I check something else in my system? Thanks in advance. Denis.
