Attention! Remarked Athlon XP Processors On the Market [06/28/2003]

We know that the normal the Athlon XP2400+ processor will operate by 1.65V. However, we were surprised to know that this Athlon XP processor operates by 1.8V.

OPN is AXDA2400DKV3C

It is thought that operating by 1.8V although it must be 1.65V specification, since the OPN showing core voltage is K has abnormalities in a product.

Why does actual core voltage differ from specification?

We consider it sure that this cause is in L11 bridges.
Although it must originally be VID=1.65 with the following photographs, it is a problem that it is the same as VID=1.60. Probably it is reconstruction using AXDA1800DUT3C.

AXDA **** DLT3C L=1.50V
AXDA **** DUT3C U=1.60v
AXDA **** DKT3C K=1.65v
Although the bridge of VID=1.8V was shown for comparison, the product whose core voltage is 1.8V does not exist in an actual product.

There are abnormalities also in L3 bridges.

The L3 bridges differed from normal XP2400+. It seems that it is the same as AXDA1800DUT3C by appearance. This cannot be seen from a photograph, though regrettable. We think that some L3 bridges may be buried with a conductive material.

We know that the same thing as this exists also in the following pages.
