What the Phenom II X6 1065T is
The AMD Phenom II X6 1065T is a six core Thuban desktop processor that AMD released in December 2010. It runs six K10 cores at 2.9 GHz base with Turbo Core to 3.4 GHz, so 6 cores give 6 threads. Each core carries 512 KB of L2 cache for 3 MB in total, backed by 6 MB of shared L3 cache. Power is rated at 95 W on a 45 nm process.
The 1065T is the fastest 95 W Thuban, 100 MHz above the 1055T at the same power. Sources including Wikipedia and board lists rate it at 95 W with part HDT65TWFK6DGR, not 125 W. Against the 1075T it trails by 100 MHz but draws 30 W less, which suits towers with modest delivery. Against the 1090T Black Edition it trails by 300 MHz base with a locked multiplier.
There is no integrated graphics on this die. Board video comes from 7 and 8 series chipsets where fitted.
Socket and motherboard compatibility
The Phenom II X6 1065T fits Socket AM3 with 938 pins. Boards need a BIOS that lists Thuban, with native support on 8 series and a late 2010 update on 7 series.
AM3 chips also fit AM3+ boards. It also boots on AM2+ DDR2 boards after a BIOS update. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory support is DDR2 up to PC2-8500 and DDR3 up to PC3-10600 in two channels. A 2 by 4 GB DDR3-1333 kit suits most 1065T towers.
HyperTransport 3.0 links the CPU to the chipset at 2.0 GHz. PCIe Gen 2 slots hang off the chipset.
Cooling is the stock 95 W heatsink on the 48 × 96 mm mount.
Upgrade paths
On Socket AM3 the upgrade is the 1090T or 1100T Black Edition for higher clocks and an unlocked multiplier at 125 W. Beyond AM3, DDR3 carries to AM3+ while DDR4 needs a new platform. The 125 W figure sometimes listed for the 1065T could not be verified in two sources, so this page uses the 95 W rating from Wikipedia and board lists.
