Titolo: Mendocino300 : di che settamana è ?

Ho appena acquistato due  Mendocino 300, uno per me ed uno per un mio amico,
entrambi vanno a 450 a 2.0, senza scaldare troppo.....
Sul mio c'è questa sigla:  08460685  - SL2WM.
Per quanto ne so dovrebbe essere della 46 settimana, ma mi sembra strano
dato che viaggiano entrabi a 450 tranquilli......
Boh, ditemi voi.....
Grazie

secondo le ultime informazioni di Anand, quella della data di fabbricazione
e' una bufala.... inoltre la data esatta di fabbricazione del chip e' quella
riportata davanti (e non dietro dove c'e' la sigla, che e' quella di
assemblaggio della sec).
cmq sembra che i chip + oc siano quelli che riportano una specie di simbolo
strano... sotto ti metto la pagina di Anand (sono pigro.... non mi va di
andare a verificare l'esatto link.....):

 I now believe that while we have all been looking at the white label on the
back of the CPU to divine the information necessary to determine our
potential success, we have been looking in the wrong place! If you look at
this graphic of the label, you’ll see that what we thought was the
production week is listed as 34.
I’ve now come to the conclusion that this is actually the packaging week and
that the true production week is found on the front, upper-right of the
chip.
I’ve also discovered that a specific set of symbols is very critical in
determining ahead of time if your odds of hitting 450 will be good or bad! I
will try to illustrate what appears on the front right of the CPU and what
the goods ones should look like:
(Symbol) NM2 9839
94V-0
or
(Symbol) RU M1
94V-0 9843
The first one the symbol looks sort of like a 4 leaf clover in an eye.
The second one the symbol has the word COMPEQ inside an oval. The "RU" is
actually reversed and tilted to the left on the CPU.
Note the numbers "9839" and "9843". The first was from the batch labeled
week 45 and the second was from the bad half of the group labeled week 46. I
now believe that this is the true production week of the CPU.
Now, here’s the stunner. The chips containing the first set of symbols were
the ones that all performed and nearly all required no voltage increase. The
second set of symbols were the dogs. I decided to pull out the CPU’s I’d had
in the past that hadn’t performed and, sure enough, they all had the second
symbol, regardless of production week! For additional verification, I
borrowed a half-dozen of variety two from my local distributor, and these
were weaklings also.
I would also like to note that the deadliest combination seems to be the
darker green PCB and the "COMPEQ" chips. To the best of my knowledge this
has never been noted anywhere on the web!
So, after this week’s testing, the total is now 77 Celery’s. Out of this
week’s total of 24, 20 did the 450 dance, but 2 required 2.3v core to do it.
This gives us a success rate of 83.3%, which is below the norm.
To-date, of the 77 tested, 68 were successful for 88.31%. Discounting this
recent lousy crop, we were well above 90% You can bet I’ll be avoiding the
"COMPEQ" symbolled chips from now on!
Many rumors have been flying that the more recent slot version 300A’s have
not been as overclockable as previous versions. I don’t believe this to be
true, unless Intel has switched production to the second symbol I’ve
outlined above. I have no idea what these two different versions mean, only
that we need to stay away from the second one.
It will be interesting to see which CPU’s are still in inventory, whether it
be the "Cloverleaf" or the "COMPEQ". Stay tuned for future developments.

Sono della 46 settimana(terza e quarta cifra della settimana) e hai
avuto molto ma molto culo ha trovarne due cosi!!!!!

strano
 
www.anandtech.com
Moolto interessante! grazie!
Il mio mendocino 300 ha infatti il simbolo "buono", l'occhio con dentro un
simil quadrifoglio, con la sigla NM2  94V-0 , e  (più grande) 9841 (e non
9839 come l'esempio).
A quanto pare Anand ci ha proprio azzeccato.....
Per saperne di più, perchè tutti coloro del NG che hanno un mendocino300 non
segnalano il famoso simbolo posto in alto a destra dellla cpu stessa?
Per curiosità e per aiutare coloro che sono interessati all'acquisto della
suddetta cpu.
