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

What the Pentium III Xeon 700-2M 5V-12V is

The Intel Pentium III Xeon 700-2M 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 2 MB full-speed cache doubles the 1 MB option at matching clocks and power, which is why the 2M string suits database servers with large working sets. Intel launched 700 MHz Xeon parts in 1 MB and 2 MB options on May 22, 2000. The chip supports MMX, SSE and four-way SMP.

Mid server clocks with a large ECC cache suit Slot 2 database boards with registered SDRAM. The 7x integer ratio is clean for 100 MT/s boards. That is why the 700-2M shipped in quad-capable database boxes.

Socket and motherboard compatibility

The 700-2M 5V-12V fits Slot 2 servers wired for 5V-12V regulation. It needs a 330-lead SC330 board with a 100 MT/s bus and a BIOS that lists the 5V-12V 700-2M 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 5V-12V string accept cartridges with 29.6 W heatsinks each.

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 2.8V such as Intel Pentium III Xeon 700-2M 2.8V keeps clocks and cache while changing regulator path. A Xeon 700 5V-12V with 1 MB on the same list trims cache 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 shared by both cache options.
