Are one of them fake or do they have the same sspec?
The one in the library

hard to tell without seeing the chips and checking them. I am suspicious of the one in the library. One interesting test would be to put it side by side with another known good pentium. To see if it is shorter in height, and lighter in weight.
I have been giving my fake (remark) ES pentium a thrashing recently.. it is remarkable how good the printing is on the top ( the white Intel pentium) .. it runs HOT too. lol |

I have both of them and believe that they're geniune.
Here is the information about the two cpus
PCPU3V100:
PCPU3V100 SZ996
L5281591-0641
BP80502100:
BP80502100 SZ996
L6062830-0061
All boxset Pentium produced after the year 1995 week 30 will be classified as BP Pentium.
I guess Intel use the same stepping because they're identical other than the part no. (PCPU3V100 and BP80502100) Just like the event happen to SU072, same stepping code printed on Classic Pentium 166Mhz and Pentium Overdrive 166Mhz

BTW,
I discover an interesting thing. All of my PCPU3V100 (with TM trademark) are produced on 1995 week 21.
L5211298-5393
L5211294-3516
L5211294-3100
L5212642-0554
Does anyone have other production week?

LOL
I know what you mean.. I am too lazy to scan new chips. I have to wait for some tasty ones before I scan anything.
Give it a try. I have been testing some of mine, I will do them all. It is more fun that it sounds - I have a ton of computers going back to the mid 80's so its easy for me to do, and I can see this might be difficult for new collectors. Testing also adds another dimension to just collecting cpus. Some people collect for the financial reward, but true collectors will get the most from their collection on test  |

To the contrary, I've spent much time on taking photos for my cpus. Once they arrive, they will be cleaned, numbered and recorded. It's time-consuming activities. Besides, I have a relatively small room. It's inconvenience to test cpu.
I collect fake cpus now. I bought several fake Pentium in Hong Kong. Most of them are pentium 100. The highest frequency is P166 with black heatsink. It's quite interesting.
I don't use the system testing to test the cpu but use the "outlook testing" and "number matching" method to "certifify" the cpu. Outlook testing is compare the outlook of cpu, no extraordinary printing on cpu and the front number is matched with the back. I do rely on this two method to identify the cpu.

| I use the methods you describe, but also CPU id strings and instruction testing. The software was originally designed to test for faulty cpus, but it now has a second life checking function and helping to identify fakes. The fake printing is so good on some cpus it is not easy to tell just from looking externally. |

I'm the same.
I tested most of my 486 and Pentium as far as POST on Sunday (just to make sure they work), and will be doing the same with ther rest of my socketed 486 and Socket 7 chips soon. Other chips will also be getting tested, and I am looking for adapters to test PQFP chips in socketed boards. I'll get onto the older chips as soon as I get suitable systems. I want to know I ahve a collection of working chips, not just pretty thing, and for me knowing that I have personally tested every chip in my colection, or am going to, that is half the pleasyre of my collection.
Also, once I ahve tested every chip as far as POST, I will then be going farther and setting them all up in systems (a few at a time probably) to test by loading DOS, running my CPUID code (because it is the most complete DOS based CPUID code I know) and then I'll run some kind of DOS based benchmarking app, to thoroughly test every chip in my collection. Any that don't work (and I ahve about 5% failure rate so far) will get replaced when I find replacements
I collect the technology, not just the eye candy, although obviously it's nice to ahve the best example I can get of any chip (visaully and functionally)

That theory sounds very reasonable!
Thanks Billy!

Yes, they have the same sspec.
PCPUxVxxx is the early prefix of Boxset Pentium, and then changed to BPxxxxx.
I thought they have the same core too, just changed the prefix.
Regard,
Yan

Just like the same sspec SZ994 on BP8050275 and PCPU3V75.
The same sspec SZ995 on BP8050290 and PCPU3V90 too.
