What the Opteron 8350 (B3) is
The AMD Opteron 8350 (B3) is a 2.0 GHz multi-socket server quad core from April 9, 2008. It runs four K10 cores at 2.0 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 scales the native K10 server quad to four and eight socket Socket F machines, seated here in Fr2 1207-land infrastructure that accepts Socket F packages. The B3 stepping, part OS8350WAL4BGH, 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 8350 (B3) fits Socket F multi-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 dense chassis with directed airflow.
Upgrade paths
On Socket Fr2 the upgrade is the AMD Opteron 8352 (B3) at 2.1 GHz or the AMD Opteron 8354 (B3) at 2.2 GHz on the same fixed stepping. The AMD Opteron 8350 HE at 2.0 GHz drops to 79 W for efficient racks. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.
