Ah, an "Intel Confidential" chip. Anything with the SSpec that starts with a "Q" is going to be tough to figure out unless you turn the machine on. To bring the information you presented together:

ATPO mark: L237A243
SN mark: 0124
SSpec: QRBOES
Assembly: Malaysia
Part/OEM Number: 88532PE003512

After some searching I found a page that listed a processor with the S-Spec QRBOES. It apparently belongs to a 3.06GHz Northwood Pentium 4, C1 stepping w/ 512KB of L2 cache. It doesn't follow what I'd expect on the Part/OEM number which identifies it as E0 stepping. If the rest of that OEM Number is right (the 885 in the beginning doesn't match anything though) I think this is a 1.5v part. It could be the 3rd speed tier of this paticular sample, as the 03 following the E0 usually designates that (and is beyond the 70's for "real" processors).

It looks like you have a good chip on your hands though, if I got it ID'd right. The C1 stepping goes decently far. Apparently someone got his to 3787MHz with the standard cooler (likely not stable), while another person got it to 4293MHz on LN2.


Definately put it together and see what it is with something like CPU-Z. Post back and tell us what it is.
