What the Turion X2 Ultra ZM-87 is
The AMD Turion X2 Ultra ZM-87 is a 2.4 GHz mobile dual core from the June 2008 Puma platform launch. It runs two Griffin cores at 2.4 GHz with no turbo, so 2 cores give 2 threads. Cache is 1 MB of L2 per core, 2 MB total, on a 65 nm process. Power is rated at 35 W on Socket S1.
The ZM-87 shares its 2.4 GHz and 35 W rating with the ZM-86, but steps the HyperTransport link up to 2200 MHz against 1800 MHz on the rest of the launch line. Turion X2 Ultra implements three voltage planes, one for the northbridge and one per core, for finer battery management than Athlon-branded Griffin parts.
Socket and motherboard compatibility
The ZM-87 fits S1g2 Puma notebooks with DDR2 SO-DIMM slots and a BIOS that lists Griffin Turion parts. It does not fit S1g1 boards despite the shared 638 pins. Display comes from the notebook board graphics. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2-800 SO-DIMMs in two channels through the on-die controller, with no ECC support.
A 2200 MHz HyperTransport link ties the CPU to the mobile chipset. PCIe slots and board graphics hang off the chipset.
Cooling is the notebook vendor heat pipe assembly for the exact chassis, with PowerNow! trimming clocks and voltage on battery.
Upgrade paths
On Socket S1 the upgrade is the AMD Turion X2 Ultra ZM-88 at 2.5 GHz for the fastest Griffin, or the AMD Turion X2 Ultra ZM-86 at the same 2.4 GHz on the standard link. The AMD Turion X2 Ultra ZM-85 at 2.3 GHz shares the faster link at a lower clock. A swap must stay within the thermal design the chassis was qualified for.
