What the Opteron 2352 (B3) is

The AMD Opteron 2352 (B3) is a 2.1 GHz server quad core from April 2008. It runs four K10 cores at 2.1 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 B3 stepping, part OS2352WAL4BGH, carries the proper fix for the TLB erratum in earlier steppings. 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 2352 (B3) fits Socket F two-socket server boards seated in Fr2 infrastructure, with a BIOS that lists B3 Barcelona 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 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 2.2 GHz or the AMD Opteron 2356 (B3) at 2.3 GHz on the same fixed stepping. The AMD Opteron 2352 is the same speed on the older B2 stepping. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.

Frequently asked questions

What socket does the Opteron 2352 (B3) use?

Socket Fr2, the 1207-land infrastructure that accepts Socket F server packages.

How many cores does the Opteron 2352 (B3) have?

Four cores and 4 threads at 2.1 GHz with 512 KB of L2 per core plus 2 MB of shared L3.

What is the difference between the Opteron 2352 (B3) and 2352?

The 2352 (B3) is the fixed stepping without the TLB erratum that affects the B2-based 2352.
