What the Pentium III Xeon 933 5V-12V is
The Intel Pentium III Xeon 933 5V-12V is a 933 MHz single-core server processor from May 2000. It runs one P6 Cascades core at 933 MHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 256 KB of full-speed L2 with 32 KB of L1 on a 180 nm process. Power is rated at 29.6 W in a Slot 2 SECC cartridge on a 133 MT/s front side bus with a 7x multiplier on the 5V-12V regulator path.
The 5V-12V string shares clocks, cache and power with the 2.8 V string while fitting boards wired for higher input rails, which is why server lines stock one or the other. Intel launched both 933 strings on May 24, 2000. The chip supports MMX, SSE and two-way SMP.
Matching clocks with regulator choice suit 5V-12V Slot 2 lines. That is why the 5V-12V string shipped in 5V-12V server lines.
Socket and motherboard compatibility
The 933 5V-12V fits Slot 2 servers wired for 5V-12V regulation. It needs a 330-lead SC330 board with a 133 MT/s bus and a BIOS that lists the 5V-12V 933 string. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
5V-12V rack servers are the natural match. Boards listing the string accept cartridges with 29.6 W heatsinks.
Memory, PCIe and cooling
Memory is registered ECC SDRAM through the server chipset, matched to the board sockets. The cartridge has no memory controller. Server boards commonly run ECC pairs.
A 133 MT/s front side bus ties each cartridge to the chipset, while PCI hangs off the chipset. No PCIe lanes originate on the cartridge. Cooling uses SECC heatsinks on the retention cage.
Upgrade paths
On the same slot, a move to a Pentium III Xeon 933 2.8V such as Intel Pentium III Xeon 933 2.8V keeps clocks while changing regulator path. A Xeon 866 5V-12V such as Intel Pentium III Xeon 866 5V-12V drops clocks at equal power.
A move to Foster Xeon needs Socket 603. The Slot 2 page lists the range. Note: the queue row lists 30 W; this page uses the verified 29.6 W.
