What the Opteron 2346 HE (B3) is
The AMD Opteron 2346 HE (B3) is a high-efficiency 1.8 GHz server quad core from April 9, 2008. It runs four K10 cores at 1.8 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 68 W TDP.
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 B3 stepping, part OS2346PAL4BGH, carries the proper fix for the TLB erratum in earlier steppings. The HE suffix marks a high-efficiency bin well under the 95 W standard envelope, with a 1.0 GHz HyperTransport link.
Socket and motherboard compatibility
The 2346 HE (B3) fits Socket F two-socket server boards seated in Fr2 infrastructure, with a BIOS that lists B3 Barcelona HE parts. Standard Socket F packages seat in Fr2 machines per the platform compatibility note. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is registered PC2-5300 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 68 W envelope in dense chassis with directed airflow.
Upgrade paths
On Socket Fr2 the upgrade is the AMD Opteron 2347 HE (B3) at 1.9 GHz or the AMD Opteron 2350 HE at 2.0 GHz within the HE line. The AMD Opteron 2344 HE (B3) at 1.7 GHz is the cheaper HE part. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.
