I'm thinking there's got to be *something* wrong with that extra 256..or the CPU being able to access that extra 256....???
..... hmm apparently you don't buy too many CPU's. Locking and rebadging is common place in CPU's. Think of it this way, Processors (INTEL and AMD) come in a string of different clock speeds. It would not be cost effective for a company like AMD or INTEL to create a fabrication plant for each CPU based on clock speed. Insted they just create fabs for the specific family. Based on the quality of production, the processors are the sorted to their prospecitve speeds. Processor manufactureres are continually optimizing their production processes, as they do this then there production quality increases. In other words many times you get a faster processor, locked at a lower speed. It doesn't cost AMD any more or any less money to produce a Thorton compaired to a Barton. Lower clock speeds exist to meet the demand for people who may not want to spend that much money, and for OEM's to diversify their product line and market them accordingly.
Thats why people are able to push a Barton 2500+ to Barton 3200+ speeds consistantly without any special cooling or voltage increases. Where as several months ago it was hit or miss with the 2500+.
Or if you look at the INTEL side, it is now common place to push a 2.4GHz P4 HT processor to 3.2GHz or higher.
From my understanding with the Thornton processor, if its locked then you may have bridge a few contacts to "unlock" the extra 256 L2.
This kind of stuff happens all the time. Then only down side to this, is that if technically voids your warantee.
