Well, as I start this reply it's 1:23pm.
I just OC'd all four of my S3's to 237.5, I have a dentist appointment at three. So after I hit the post button. I'm gonna do a single refresh on all four to see web stats. After that I'll let everything be til probably around 4pm when I get back. If everything looks good, I'll leave them all on 237.5 for 24hrs.
If after that, everything still looks good. Then about this time tomorrow or so I will take the proverbial plunge and try 250 on one of them for 24hrs. If that holds good, then I'll set the second at 250 and let run 24hrs, so on and so forth til I t all four on 250 if I'm lucky.
Between 237.5 & 250, is there any other freqs, I think I saw someone say 240 or something a few pages back.
