athlon II x4 640 cacdc ac

[ceferino1985]

Good morning, I bought an amd athlon II x2 640 (ADX640WFGMBOX) at amazon and it has this stepping code: cacdc ac 1221pgt, what does this mean? Is this processor core deneb?

Hi, that part number is an Athlon II X4 Quad-core processor. The core name is Propus. It is derived from Deneb, but the L3 cache is disabled in Propus. It will be slightly slower and consume less power than a Deneb at the same frequency. You can read more specifications here:

This procesor has this stepping code: cacdc ac 1221pgt, and i thought maybe it would be a deneb core, because the link that gambling does not appear that stepping code. then you say that it is a native propus and cannot activate the cache l3?

pd: excusame for my bad English.

AC in the stepping code indicates that the core is derived from Deneb. This should mean that the circuitry for Phenom II X4 Deneb is present, but the L3 cache is disabled.

Since the resulting product is Athlon II X4, most people call this a, "Propus chip", even though it was originally manufactured as a Deneb chip.

Processors with AD in the stepping code were manufactured as "native" Propus core; without any L3 circuitry. More here:

mmm despite having been manufactured as a deneb it has no cache L3 to unlock? Try it but without any result.

It may have but there is no guarantee that it will unlock. You are out of luck probably.

[Guest]

do to unlock the L3 cache I require some chipset in particular? I have the nb 760 g and sb 710 in an asus m5a78l-m lx.
