That was what happened to me this week when the 3.06 that I bought turned out to be a Mobile. I couldn't get the multiplier to change from it's default of 12x. I was able to get the FSB up to 200 (2.4ghz), but couldn't find a low enough divider on a Gigabyte 845PE board, so that was about it. I returned it.BigBadBiologist said:Most P4-M CPUs work in desktop boards fine, with one major issue: they default to a 12x multiplier (some later ones may actually default to a 9x multiplier). So, if you want to get a decent speed out of the system, you need a board that will allow good overclocking FSB. Also, the P4-Ms don't have IHSs, so there may be contact issues for a lot of HSF units. If you do have a high FSB board and a decent HSF, then most of them hit 3GHz without problem.
If it is a P-M, it will not work in a normal desktop board without the Asus 479 adapter.

Actually I purchased it from a guy on these forums. I believe it was an honest mistake, though. It was an ES that he'd bought on faith; the CPU had few markings other than a couple of numbers and the word Confidential. He hadn't actually tested it before I bought it from him. Anyways, he cheerfully took it back when I made the painful discovery. I ordered a real SL6S5 from a vendor in VT for $183 delivered.Spazilton said:You have to be damn careful of people on Ebay selling the 3.06 processors. A lot of people will try to pass off the Mobiles as Desktops.
Make sure the stepping has a xx6xx in it. If it has a 7 its not the 533/HT.
Seen it a lot on Ebay. The genuine ones go for at least $200.

That's what I thought I could do. CPUZ showed the multiplier as 12 (23), so I figured there was some way to unlock the multiplier, but I couldn't on two Gigabyte boards, an 850 and and 845; both with the latest BIOS. I tried for hours before I just gave up. It was a shame, because I thought that I was missing something obvious. Oh well...BigBadBiologist said:well, if it is an ES, then you may be ok because the multipliers on ES chips are normally unlocked. So if your BIOS supports it, you can probably change it to whatever you want without having to up the FSB.
They got more, as well as some SL6PGs for the same price:Spazilton said:$183 for an SL6S5 is a good deal.
