AMD Opteron 2354 socket: Socket Fr2
The AMD Opteron 2354 uses the Socket Fr2 socket. It is a 95 W quad-core Barcelona server part at 2.2 GHz with 4x512 KB of L2 plus 2 MB of shared L3, on the older B2 stepping.

What the Opteron 2354 is
The AMD Opteron 2354 is a 2.2 GHz server quad core from April 2008. It runs four K10 cores at 2.2 GHz with no turbo, so 4 cores give 4 threads. Cache is 512 KB of L2 per core under a shared 2 MB L3 on a 65 nm process. Power is rated at 95 W TDP with 75 W ACP.
Barcelona is the native K10 server quad for two-socket Socket F machines, seated here in Fr2 1207-land infrastructure that accepts Socket F packages. The untagged 2354 is the B2 stepping, part OS2354WAL4BGD, which carries the hardware TLB bug that the B3 version fixed. Its HyperTransport link runs at 1.0 GHz. ACP reflects average data-center power against the 95 W thermal ceiling.
Socket and motherboard compatibility
The 2354 fits Socket F two-socket server boards seated in Fr2 infrastructure, with a BIOS that lists Barcelona parts. Standard Socket F packages seat in Fr2 machines per the platform compatibility note, and boards may need the TLB erratum workaround BIOS for the B2 stepping. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is registered DDR2 ECC in two channels per socket through the server board design.
A 1.0 GHz HyperTransport link ties the CPU to the server chipset and the sockets together. PCIe slots hang off the chipset.
Cooling uses vendor qualified server heatsinks with threaded backplates for the 95 W envelope in 1U and 2U chassis with directed airflow.
Upgrade paths
On Socket Fr2 the upgrade is the AMD Opteron 2354 (B3) at the same 2.2 GHz on the fixed B3 stepping, or the AMD Opteron 2356 (B3) at 2.3 GHz. The AMD Opteron 2350 HE drops to 79 W for efficient racks. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.
Frequently asked questions
What socket does the Opteron 2354 use?
Socket Fr2, the 1207-land infrastructure that accepts Socket F server packages.
How many cores does the Opteron 2354 have?
Four cores and 4 threads at 2.2 GHz with 512 KB of L2 per core plus 2 MB of shared L3.
What is the difference between the Opteron 2354 and 2354 (B3)?
The untagged 2354 is the B2 stepping with the TLB erratum; the 2354 (B3) is the same speed on the fixed stepping.
