Limited FSB?

[bielius]

I got a intel celeron d 2.13 ghz, fsb 133. i OC it to 2.43 @ 153(or 154..) multiplier 13.
but when i go over 155, the POST starts, it shows no line(the first line is like processor:intel celeron ..bla bla bla.. ).
and it restarts, and its again the fsb on 133 @ default. any suggestions? i have tryed upping Vcore( options are- default;+0.05v;+0.10v;+0.15.)|i have tryed all but with 0.10 and 0.15 it is unstable and giving BSOD'S.)
thanks in your coming advice!!!

155 must be the systems OC limit

It may be the board's limit, or the processor's limit, I'm not sure. However, it does seem to me as if there's a barrier you're hitting.

the Bios shows that the max fsb can be set at 165. so it's probably processor. thanks guys!

There are many things that can affect max overclocking. In my case it was my old Abit motherboard that was my bottleneck. Memory, operating system, and power supply are other factors. In Windows 7 64-bit my performance and "Vista rating" is much better, than in Vista 32-bit
