Intel Pentium III Xeon 700-2M 2.8V socket: Slot 2

What the Pentium III Xeon 700-2M 2.8V is

The Intel Pentium III Xeon 700-2M 2.8V 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 2.8 V regulator path.

The explicit 2M name with direct regulation marks the database pick of the 700 set, which is why it headed quad-capable boxes with large caches. Intel launched the 700-2M strings on May 22, 2000. The chip supports MMX, SSE and four-way SMP.

Large cache with direct regulation suits Slot 2 database servers with registered memory. That is why the 2.8V 2M string shipped in 2.8 V database lines.

Socket and motherboard compatibility

The 700-2M 2.8V fits Slot 2 database servers with 2.8 V regulation. It needs a 330-lead SC330 board with a 100 MT/s bus and a BIOS that lists the 2.8 V 700-2M string. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Database 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. Database boards commonly interleave 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 700-2M 5V-12V such as Intel Pentium III Xeon 700-2M 5V-12V keeps cache while changing regulator path. A plain 700 2.8V is the same-silicon twin under a shorter name.

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