What the Pentium III Xeon 600 5V-12V is

The Intel Pentium III Xeon 600 5V-12V is a 600 MHz single-core server processor from October 1999. It runs one P6 Cascades core at 600 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 19.2 W in a Slot 2 SECC cartridge on a 133 MT/s front side bus with a 4.5x multiplier on the 5V-12V regulator path.

The 180 nm shrink with a fast bus opens the Cascades line at low power, which is why the 600 5V-12V suited entry servers with small coolers. Intel launched the Xeon 600 in October 1999. The chip supports MMX, SSE and two-way SMP.

Entry server clocks with a 19 W class envelope suit Slot 2 starter racks. The 4.5x ratio is standard for 133 MT/s server boards. That is why the 600 5V-12V shipped in entry dual boxes.

Socket and motherboard compatibility

The 600 5V-12V fits Slot 2 entry servers with 5V-12V regulation. It needs a 330-lead SC330 board with a 133 MT/s bus and a BIOS that lists the 5V-12V 600 string. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Entry rack servers are the natural match. Boards listing the string accept cartridges with 19.2 W heatsinks.

Memory, PCIe and cooling

Memory is registered SDRAM through the server chipset, matched to the board sockets. The cartridge has no memory controller. Entry 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 600 2.8V such as Intel Pentium III Xeon 600 2.8V keeps clocks and cache while changing regulator path. A Xeon 667 5V-12V such as Intel Pentium III Xeon 667 5V-12V adds clocks at higher power.

A move to Tanner Xeon drops to 100 MT/s paths. The Slot 2 page lists the range.

Frequently asked questions

What socket does the Pentium III Xeon 600 5V-12V use?

Slot 2. It is a 19.2 W Cascades server part at 600 MHz.

What memory does the 600 5V-12V use?

Registered SDRAM through the server chipset.

What is the upgrade path from the 600 5V-12V?

A 600 2.8V on boards wired for that regulator, or a 667 5V-12V for more clocks.
