What the Phenom II X4 920 is
The AMD Phenom II X4 920 is a quad core Deneb desktop processor that AMD launched on January 8, 2009 for DDR2 towers. It runs four K10 cores at 2.8 GHz with no turbo, so 4 cores give 4 threads. Each core carries 512 KB of L2 cache for 2 MB in total, backed by 6 MB of shared L3 cache. Power is rated at 125 W on a 45 nm C2 process with the HDX920XCJ4DGI part.
The 920 is the DDR2-only twin of the AM3 925 at the same 2.8 GHz and cache. The task list shows Socket AM3, but family tables and the 940-pin DDR2-only package place it on Socket AM2+, so this page files it under Socket AM2+ with Deneb. Against the 940 Black Edition it trails on clocks with a locked multiplier.
There is no graphics on the die. Board video comes from 700 series chipsets where fitted.
Socket and motherboard compatibility
The Phenom II X4 920 fits Socket AM2+ with 940 pins. All 700 series DDR2 boards with Deneb firmware boot it directly.
AM2+ chips never fit AM3 because they lack a DDR3 controller. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Socket AM3 page shows the DDR3 side.
Memory, PCIe and cooling
Memory is DDR2 up to PC2-8500 in two channels. DDR3 modules do not fit these boards.
HyperTransport 3.0 links the CPU to the chipset at up to 2.6 GHz. PCIe Gen 2 slots hang off the chipset.
Cooling is a 125 W rated tower on the 48 × 96 mm mount. Value boards with small regulators may omit 125 W quads from their CPU lists.
Upgrade paths
On Socket AM2+ the upgrade is the 940 Black Edition with an unlocked multiplier on the same board. A move to DDR3 needs an AM3 board with an AM3 processor.
Frequently asked questions
What socket does the Phenom II X4 920 use?
Socket AM2+, the 940-pin DDR2-only package. The task list shows AM3, but family tables confirm the DDR2-only AM2+ package.
How many cores does the Phenom II X4 920 have?
Four cores and four threads at 2.8 GHz with 512 KB of L2 per core and 6 MB of shared L3 cache.
What memory works with the Phenom II X4 920?
DDR2 only, up to DDR2-1066 in two channels.
