What the Opteron 1389 is
The AMD Opteron 1389 is a quad core Suzuka server processor that AMD launched in June 2009 at 2.9 GHz. It runs four K10 cores at 2.9 GHz with no turbo, so 4 cores give 4 threads. Each core carries 512 KB of L2 cache for 2 MB in total, backed by 6 MB of shared L3 cache. Power is rated at 115 W on a 45 nm process.
The 1389 tops the AM3 Suzuka line at $269 MSRP. Against the 1385 it adds 200 MHz at the same 115 W. DDR3 unbuffered ECC keeps single socket server costs below registered memory platforms.
Memory is DDR3-1333 unbuffered ECC in two channels.
Socket and motherboard compatibility
The Opteron 1389 fits Socket AM3 with 938 pins. Server boards with Suzuka firmware and ECC UDIMM slots boot it directly.
AM3 Opterons also fit AM3+ boards where listed. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR3-1333 ECC unbuffered in two channels.
HyperTransport at 2.2 GHz links the CPU to the chipset. PCIe Gen 2 slots hang off the chipset.
Cooling uses server heatsinks rated for 115 W on the 48 × 96 mm pattern.
Upgrade paths
On Socket AM3 there is no faster stock Suzuka quad, so the path is a used 1389 or a move to Opteron 3200 series. Keep it where single socket ECC towers still pay.
