What the Opteron 2358 SE (B3) is
The AMD Opteron 2358 SE (B3) is a top-bin 2.4 GHz server quad core from April 2008. It runs four K10 cores at 2.4 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 119 W TDP with 105 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 B3 stepping, part OS2358YAL4BGH, carries the proper fix for the TLB erratum in earlier steppings. The SE suffix marks a top-bin part above the 95 W standard envelope, with a 1.0 GHz HyperTransport link.
Socket and motherboard compatibility
The 2358 SE (B3) fits Socket F two-socket server boards seated in Fr2 infrastructure, with robust voltage regulation and a BIOS that lists B3 Barcelona SE 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 must be rated for 119 W on server heatsinks with threaded backplates, since sustained loads hold all four cores at full speed.
Upgrade paths
On Socket Fr2 the upgrade is the AMD Opteron 2360 SE (B3) at 2.5 GHz for the standard-bin ceiling. The AMD Opteron 2358 SE is the same speed on the older B2 stepping. The AMD Opteron 2356 (B3) at 2.3 GHz drops to 95 W. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.
Frequently asked questions
What socket does the Opteron 2358 SE (B3) use?
Socket Fr2, the 1207-land infrastructure that accepts Socket F server packages.
How many cores does the Opteron 2358 SE (B3) have?
Four cores and 4 threads at 2.4 GHz with 512 KB of L2 per core plus 2 MB of shared L3.
What is the difference between the Opteron 2358 SE (B3) and 2358 SE?
The 2358 SE (B3) is the fixed stepping without the TLB erratum that affects the B2-based 2358 SE.
