My XP3000+

I bought this Barton desktop (not mobile) CPU yesterday.

Codes:AXDA3000DKV4D Y923917A40370
AQUCA0408UPMW
It is a green one.

It runs fine, but I noticed that I could change multiplier in BIOS on my
Asus A7N8X Deluxe rev2.
Changed from 13 to 13,5 and it booted at the higher speed at default
voltage, but was not stable. When I tried 12,5, the board gave me 11,5.
Checked in wcpuid31.
I've heard that this CPU should have been factory locked, but seems as this
isn't the case. Have anybody else seen this?
Is it made on april 8.? Or is it an old part from august?

Quite possibly it's not completely unlocked If line 2 of the FID is stuck
"closed" (ie: locked, in this case) then 12.5 would become 11.5, 12.5 would
become 11.0, etc etc (see fab51). Given that you can change from 13 to 13.5,
that indicates line 1 is unlocked, and changing from 13.0 to 11.5 requires
lines 3 and 5 to be unlocked. Try changing to 7x and see if it boots at 7x
(4th line unlocked) or 11x (4th line locked).

There have been some very isolated cases of unlocked chips being reported.
There doesn't seem to be any particular pattern, with identical steppings
being both locked and unlocked (not sure about the serial-number lines
though). Since it appears that your chip is not fully unlocked, this
possibly means that the locking process is not perfect, and some of the
chips aren't locking themselves properly. You may just have been very lucky
and got one of the unlocked ones

Is it made on april 8.? Or is it an old part from august?

It's made in week 8 of 2004, ie: sometime in late Feb.
