Hi the stock speed is X12
I did post before on this site but it was closed! I took a brand new xbox and flashed it with 1.4 non-stealth 12x.straight out of the box. no updates or other games played. litteraly straight out of the box. I have been on live everyday for 3 weeks and still not banned. My friend did the same but on a console that had 1.61 but it had never been online before. He is NOT banned. I would only recommend flashing benq as it seems non-stealth f/w on other drives, has been banned. You can pick up a benq for about £25-30. My friend asked me if I would update to the new Lite-touch f/w? I said I wasn't going to, because from what I have read, this 1.4 non-stealth seems to be the only f/w to survive all ban waves. So why fix something that isn't broken lol. I hope this helps

Just to add, I dont think C4eva will back this up, because it is not ixtreme!!! The guys at ABGX said that "C4eva did not write the non-stealth f/w"
You are forgetting all the people with 5.3.
