Hi

Can some one explain how the opty steppings work (144,146,148)
they seem very complicated.

Thank you very much!!!

Here's how it works.

Opteron 144 - Mutliplier of 9
Opteron 146 - Mutliplier of 10
Opteron 148 - Mutliplier of 11

So, usually FSB of 200. Opteron 146 would be 200 x 10 = 2.0GHz

Ok now i understand that but whats this i copied and pasted it of an ebay listing:
CAB2E 0548FPDW

Thanks

That's the stepping.

CAB2E 0548FPDW

Bit in bold means it was manufacturerd in 2005 of week 48. FPDW has something do with what day of the week it was made (if I recall) and what batch of wafer was used, something techy like that but it's a long time ago I read about it.

so what would the best steping be to overclock
and what would the worst be.

so that if i ever bought one i would know wich one to buy

I wouldn't know the best stepping at the moment, it changes from time to time when a new set of chips are produced. A good place to checkout is XtremeSystems Forums, they have a lot of regular posts about steppings and overclocks. From memory (and experience) the 0540 FPxW Opteron 146s were the best, 3GHz easily, but this may have changed.

Thanks a lot for your help and that link!!!!
