Unlock and OC 2200+

Hiya

My girlfriend get me as present last Saturday the following

The L1 is unlocked (no laser cut)

I have the Shuttle AK31A Rev 3.1 (KT266A) and the A-1889 Thermaltake Silent Boost (get it for the t-bird 1000 @ 1500 i had since 2001).

I OC the FSB and give me up to 1971 Mhz (146FSB*13.5).
Above 146 FSB WinXP keep crashing and probably i cannot raise the FSB more (i use the EF BIOS which is the best for OC on that mobo). L1 look intact but i saw that some of the L3 and L5 have been cut off with lazer. Can you tell me if and how i can unlock the multiplier? I try to find out some informations how to do it easily but many articles are for Thor-A or Palomino where the L1 was locked.


Thank you.

You should have an option in the BIOS for multiplier, if you don't then another thing you can do is turn ur chip mobile, and use software to increase the multiplier.

Ehm i know where the multipl. is. I don't know how to unlock it :/
