Core Speed Stepping and BIOs Changing

Hi, I have a few different questions. Here's my specs:

Windows Home Edition
Intel Core 2 Duo E6420 @ 2.13 GHz
Intel DP965LT
1x2 gigs of Micron Tech (333 MHz); 1x2 gigs of G.Skill(400 MHz)
GeForce 8600 GT


Question 1: My Core speed is stepping from 1598 MHz - 2131 MHz and the multiplier changes from x 6.0 - x 8.0. My friend disabled stepping for me, but that did nothing.


Question 2: My BIOS settings are locked, so I can't overclock/mess with the settings. Additional Info: The date on my BIOS is 3/26/2009. I'm not sure if that is the latest version, but that was the latest one that I could find.


Question 3: Since I couldn't manually change the BIOS settings, I used SetFSB. It worked, but once I restarted my computer, the settings went back to default. (Funny Event: After I overclocked my cpu, I got into a scrim in Counter-Strike and it looked like I was speed hacking. I was running really fast for a little bit (then lagged, then repeated), and when I fired a gun, I could fire about 2 times faster than everyone else could LMAO!)


Does anyone have any clue how to fix any of these problems?


Thanks in advance TPU members!

 

for starter's get rid of that awful motherboard, if u attend to overclock, also never heard of ddr2 400mhz dimms?

 

How did you friend disable speedstepping?
