AMD Mobile Athlon 64 3000+ socket: Socket 754

What the Mobile Athlon 64 3000+ is

The AMD Mobile Athlon 64 3000+ is a 1.8 GHz standard power mobile processor from January 2004. It runs one K8 core at 1.8 GHz with no turbo, so 1 core gives 1 thread. Cache is 1 MB of L2 with 64 KB of L1 instruction and 64 KB of L1 data cache on a 130 nm process. Power is rated at 62 W in a Socket 754 package with part numbers AMN3000BIX5AP and AMN3000BIX5AR.

The 3000+ standard power sits between the 1.6 GHz 2800+ and the 2.0 GHz 3200+ in the January 2004 mainstream notebook stack, all sharing 1 MB of cache and 62 W. Desktop-replacement 3000+ parts run the same 1.8 GHz with 1 MB at up to 81.5 W for large bodies, while low power Odessa 3000+ parts run 2.0 GHz with 512 KB at 35 W for thin bodies. The standard power bin targets balanced notebooks where PowerNow handles idle savings. The chip supports MMX, SSE, SSE2, Enhanced 3DNow, NX bit and AMD64 with PowerNow.

Pricing at launch shows the stack clearly. The standard power 3000+ listed at 233 dollars, above the 193 dollars 2800+ and below the 293 dollars 3200+, all in January 2004. Those dollars place the part as a mid range notebook option with full 1 MB cache, rather than a cut down low power bin.

Socket and motherboard compatibility

The 3000+ standard power fits Socket 754 notebooks with DDR memory and Clawhammer standard power BIOS support. It needs a notebook board with Socket 754 lands, not a Socket S1 DDR2 board. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mainstream DDR notebooks are the natural match. The maker qualifies the AMN part for the 62 W heat pipe assembly, so only listed standard power models boot with correct power tables. Desktop-replacement AMA parts need larger cooling, and low power AMD parts need different voltage handling. Cross fitting across power classes without support risks febrile shutdowns under load. Socket 939 desktop boards do not accept the mobile package.

Memory, PCIe and cooling

Memory is DDR through the on-chip controller in a single channel. SO-DIMM slots and ceiling are fixed by the notebook, with the controller setting speed. The 1 MB cache reduces trips to memory, which helps at 1.8 GHz against 512 KB low power parts at higher clocks.

An 800 MHz HyperTransport link ties the CPU to the mobile chipset, while display and expansion hang off the chipset. No PCIe lanes originate on the die. Cooling is the notebook 62 W heat pipe assembly with fan control tied to CPU temperature. PowerNow drops multiplier and voltage at idle, so office use stays quiet. Service means cleaning vents and renewing paste with the maker type, not fitting a tower cooler.

Upgrade paths

On Socket 754 the direct standard power step is the Mobile Athlon 64 3200+ at 2.0 GHz with 1 MB at 62 W, while the 2800+ at 1.6 GHz offers a cooler lower clock where listed. Newark 3000+ parts at 1.8 GHz with 1 MB at 62 W on 90 nm suit later notebooks as a die shrink alternative. Beyond Socket 754 a move to Socket S1 needs a new notebook for Turion 64 ML and MT parts. The 3000+ removes with the socket mechanism, so qualified swaps need no solder work.
