Intel Pentium III Xeon 700 5V-12V socket: Slot 2

What the Pentium III Xeon 700 5V-12V is

The Intel Pentium III Xeon 700 5V-12V is a 700 MHz single-core server processor from May 2000. It runs one P6 Cascades core at 700 MHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 2 MB of full-speed ECC 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 100 MT/s front side bus with a 7x multiplier on the 5V-12V regulator path.

The plain 700 string shares clocks, cache class and power with the 700-2M string, which is why board lists often carry both names for the same cooler. Intel launched the 700 family on May 22, 2000 in 1 MB and 2 MB options. The chip supports MMX, SSE and four-way SMP.

Balanced server clocks with a large cache suit Slot 2 workgroup boards with registered memory. That is why the 700 5V-12V shipped in dual server boxes.

Socket and motherboard compatibility

The 700 5V-12V fits Slot 2 workgroup servers with 5V-12V regulation. It needs a 330-lead SC330 board with a 100 MT/s bus and a BIOS that lists the 5V-12V 700 string. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Workgroup 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. Workgroup boards commonly run ECC pairs.

A 100 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 700 2.8V such as Intel Pentium III Xeon 700 2.8V keeps clocks while changing regulator path. A 700-2M 5V-12V such as Intel Pentium III Xeon 700-2M 5V-12V is the explicit-2M twin at matching power.

A move to Foster Xeon needs Socket 603. The Slot 2 page lists the range.
