AMD Athlon 64 3600+ socket: Socket 754

What the Athlon 64 3600+ is

The AMD Athlon 64 3600+ is a 2.4 GHz single-core desktop processor from June 2004. It runs one K8 core at 2.4 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 89 W in a Socket 754 package with part number ADA3600AEP5AR.

The 3600+ sits near the top of the Clawhammer Socket 754 desktop stack, sharing its 2.4 GHz and 1 MB rating with higher priced 3700+ and 3800+ neighbours on different sockets. It uses a 200 MHz system clock with a 12x multiplier at 1.50 V and an 800 MHz HyperTransport link. AMD placed it for buyers who wanted 1 MB of cache without moving to Socket 939 dual channel boards. The chip supports MMX, SSE, SSE2, Enhanced 3DNow, NX bit and AMD64 with CoolnQuiet control.

Model numbers need care here. A Socket 754 3400+ at 2.4 GHz with 512 KB shares clocks but halves the cache, while the 3600+ keeps 1 MB. That cache difference decides performance in games and encoding more than the 200 MHz gap to slower Clawhammer parts. Part numbers with AEP5AR mark the CG stepping with 1 MB for Socket 754.

Socket and motherboard compatibility

The 3600+ fits Socket 754 desktops with DDR memory and a BIOS that lists Clawhammer 1 MB parts. It needs a 754-pin board with single channel DDR slots, not a Socket 939 board with dual channel slots. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mid range DDR towers with AGP graphics are the natural match. Boards that run the 2800+ or 3200+ Clawhammer parts normally accept the 3600+ with the same 89 W cooler class, since power and bus stay flat. Late 90 nm Venice support is board specific, so the maker list decides whether a die shrink part boots. Forcing the chip into Socket 939 risks bent pins.

Memory, PCIe and cooling

Memory is DDR through the on-chip controller in a single channel. The 1 MB L2 keeps more working data on die than 512 KB parts, which helps at the same 2.4 GHz clock. Boards take up to three unbuffered DIMMs, with the controller setting speed.

An 800 MHz HyperTransport link ties the CPU to the chipset, while AGP or PCIe slots hang off the chipset for graphics. No PCIe lanes originate on the processor. Cooling uses two-hole heatsinks at 90 mm spacing rated for 89 W. CoolnQuiet lowers clocks at idle, so office use stays quiet with normal case airflow.

Upgrade paths

On Socket 754 the 3600+ is near the ceiling, so same socket upgrades are limited to Newcastle and Venice parts where listed, such as the 3400+ Newcastle at 2.4 GHz. Socket 939 offers the 3700+ San Diego at 2.2 GHz with 1 MB and the 3800+ Venice at 2.4 GHz with 512 KB as dual channel steps with new boards. A move to Socket AM2 needs DDR2 memory with Orleans parts. The 3600+ removes with the lever, so swaps need no solder work.
