AMD Opteron 8350 socket: Socket Fr2

The AMD Opteron 8350 uses the Socket Fr2 socket. It is a 95 W quad-core Barcelona server part at 2.0 GHz with 4x512 KB of L2 plus 2 MB of shared L3 for multi-socket racks, on the B1 stepping.

What the Opteron 8350 is

The AMD Opteron 8350 is a 2.0 GHz multi-socket server quad core from September 10, 2007. 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 multi-socket Socket F machines, seated here in Fr2 1207-land infrastructure that accepts Socket F packages. The untagged 8350 is the B1 stepping, part OS8350WAL4BGC, 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 8350 fits Socket F multi-socket server boards seated in Fr2 infrastructure, with a BIOS that lists early 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 B1 stepping. 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 8350 (B3) at the same 2.0 GHz on the fixed B3 stepping, or the AMD Opteron 8352 (B3) at 2.1 GHz. The AMD Opteron 8350 HE at 2.0 GHz drops to 79 W. Beyond Fr2 a move to a newer Opteron platform needs new boards and memory.

Frequently asked questions

What socket does the Opteron 8350 use?

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

How many cores does the Opteron 8350 have?

Four cores and 4 threads at 2.0 GHz with 512 KB of L2 per core plus 2 MB of shared L3.

What is the difference between the Opteron 8350 and 8350 (B3)?

The untagged 8350 is the B1 stepping with the TLB erratum; the 8350 (B3) is the same speed on the fixed stepping.
