AMD Opteron X3418 socket: Socket FP4

What the Opteron X3418 is

The Opteron X3418 is a quad core, four thread server SoC with a 1.8 GHz base and up to 3.2 GHz boost. It carries 2 MB of shared L2 cache with no L3 on the 28 nm process. HPE lists a 12 to 35 W configurable range, with databases naming 15 W nominal.

Two Excavator modules give four cores for virtualization hosts and edge servers where ECC matters. Toronto names this server silicon, distinct from Brown Falcon G-series parts. The multiplier is locked.

Radeon R7 graphics with 6 compute units near 800 MHz cover setup displays; one source lists up to 720 MHz instead, so the 800 MHz database figure is kept with the conflict noted. Memory runs as DDR4-2400 ECC in two channels. The chip is soldered in the FP4 BGA package.

Socket and motherboard compatibility

The X3418 is soldered to the server board in the Socket FP4 package and cannot be replaced. Upgrading means replacing the board or the whole microserver. HPE qualified it for the MicroServer Gen10 beside the X3216 and X3421.

Boards tune the same silicon between 12 W quiet operation and 35 W performance modes. ECC UDIMMs correct single bit errors during long uptimes. Check the server vendor list for the exact SoC before ordering boards.

There is no socket retention or cooler choice beyond the vendor heatsink. Service follows the server maker manual.

Memory, PCIe and cooling

Memory support covers DDR4-2400 ECC in two channels up to 32 GB on MicroServer boards. ECC corrects single bit errors during continuous packet work, which protects routing tables. Two matched UDIMMs give dual channel speed.

PCI Express arrives as version 3.0 with 8 lanes from the SoC for NICs and storage controllers. Microservers wire SATA through the chipset for drive bays. There is no cooler to swap, so thermal design stays with the vendor.

Upgrade paths

There is no CPU upgrade path on soldered FP4. The only moves are more ECC memory where slots allow it, larger drives, or a whole server replacement. The X3421 adds clocks on the same package where listed.

Staying on this board, ECC memory and matched DIMMs help more than chasing clocks. The locked multiplier removes overclocking as a tuning option.
