The first step is to be sure you are stable without OC'n.
I have fond memories of my Extreme .. Start with the Memory.
This was much the same as the V is now.. (T2 & Read to Read 5)
There is all types of testing software out there/here .. and this has been discussed
much .. but my favorite down and dirty trick to test the memory is simply to
put the 'rig' to 'sleep' .................. if it wakes right up without issue .. thats stable.
4ghz will be no issue .. (its all about the memory)
(btw .. the font above is extremely hard to read ..) Best of Luck.c.
