Hi. My current setup is an overclocked P4 2.6@3.2ghz @1.6V (actual) 1.54 effective, on Abit IS7 with 1.7 bios.
Lately i've purchased the Zalman CNPS7000 heatsink and installed it on my cpu which allowed me to increase the clock speed from the previous overclock of 3055 to 3200. However, even after increasing the voltage from 1.575 to 1.60 I have noticed this unusual occurance as of late. Sometimes, the mouse will become very jerky and when I move it, the cursor will move a little and get stuck then move again (in essence as if one motion is divided into 2 or more making it impossible to operate the desktop). Naturally I closed my Seti@home and all other programs and under Perfomance in Windows Task Manager my CPU Usage still remained extermely high and fluctuated between 43% and 49% idle. I then checked in Processes for any unusual processes, but was unable to find anything I haven't seen before.
I am not sure what is causing the problem. What surpises me is that when I lower the clock speed to my previous overclock of 3.055ghz, the problem disappears. My educated guess is to increase the voltage even more from the 1.60 setting. I have a Costa Rica chip so it might require higher voltage for stability than do the Malaysians. However, I personally do not associate this "lag" as instability and that is why I am unable to find a solution.
Any help or suggestions for a solution of this problem would be appreciated.
