AMD Athlon 64 3200+ (CG) socket: Socket 754

What the Athlon 64 3200+ (CG) is

The AMD Athlon 64 3200+ (CG) is a 2000 MHz single-core desktop processor from September 2003. It runs one K8 Clawhammer core at 2000 MHz with no turbo, so 1 core gives 1 thread. Cache is 1024 KB of full-speed L2 with 128 KB of L1 on a 130 nm process. Power is rated at 89 W in a Socket 754 micro PGA package with part numbers ADA3200AEP5AP for C0 stepping and ADA3200AEP5AR for CG stepping on an 800 MHz HyperTransport link with a 10x multiplier at 1.5 V.

Clawhammer carries the full 1 MB L2 of the first Hammer desktop die, which is why the 3200+ at 2000 MHz leads Newcastle 3200+ parts at 2200 MHz with 512 KB in cache-sensitive office tasks despite a lower clock. AMD launched the 3200+ on September 23, 2003 with the FX-51 as one of the first two Athlon 64 desktop parts. The chip supports MMX, SSE, SSE2, Enhanced 3DNow, AMD64, Cool n Quiet and NX bit on CG stepping.

Full cache with a single DDR channel suits early Socket 754 towers with AGP graphics. The 89 W envelope needs a standard Socket 754 tower cooler with normal case airflow. That is why the 3200+ shipped in performance desktops with discrete AGP cards.

Socket and motherboard compatibility

The 3200+ (CG) fits Socket 754 desktop boards with Clawhammer support. It needs a 754-pin board with an 800 MHz HyperTransport path and a BIOS that lists the 89 W 3200+. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Early AGP towers are the natural match. Boards listing Athlon 64 3200+ with 1024 KB accept the chip with an 89 W cooler. The CG stepping adds the NX bit over C0, so a BIOS from late 2003 or later is the safe baseline. Mobile-only Socket 754 boards with 35 W power tables are not the target for this 89 W desktop part.

Memory, PCIe and cooling

Memory is single-channel DDR1 through the on-chip controller, matched to the board DIMM sockets. The controller runs DDR speeds up to 400 MHz with up to three unbuffered DIMMs, with the exact speed set by the board. Registered DIMMs up to four sockets are possible when the board wires them.

An 800 MHz HyperTransport link ties the CPU to the board chipset at up to 3.2 GB per second in each direction, while AGP and PCI slots hang off the chipset. No PCIe lanes originate on the die. Cooling uses the Socket 754 retention bracket with a cooler rated for 89 W. The 40 mm by 40 mm organic substrate needs even mounting pressure across the heat spreader.

Upgrade paths

On the same socket, a move to a faster Socket 754 desktop part such as AMD Athlon 64 2800+ or a 3400+ keeps the board and memory when the support list names it. The 3400+ at 2200 MHz with 1024 KB adds clock and cache headroom on the same 89 W cooler class. A Venice 3000+ on 90 nm cuts power at similar performance when the BIOS lists Palermo and Venice.

A move to Socket 939 needs a new board for dual-channel DDR with a 1000 MHz link. Socket AM2 moves to DDR2. The Socket 754 page lists the full codename range from Clawhammer to Venice for planning. Note: the queue row for this part lists 2.2 GHz and January 2003, which matches a Newcastle 3200+; this page uses the verified Clawhammer CG values of 2000 MHz with 1024 KB from September 2003.
