Purpose-built server processor

The IBM 00Y2852 integrates an Intel Xeon E5-2620 v2 six-core processor running at 2.1 GHz with 15 MB L3 cache and twelve threads via Hyper-Threading. It targets administrators refreshing or repairing LGA 771 platforms that require DDR3 1866 memory support and 7.2 GT/s QPI interconnects. Buyers needing higher core counts or newer socket standards should look elsewhere.

Bare die delivery and mounting

The unit ships as a bare processor without heatsink, fan or retail packaging, so the builder must supply a compatible LGA 771 cooler and apply thermal interface material. The absence of bundled cooling means mechanical clearance and mounting hole alignment must be verified against the server chassis before installation. Systems expecting a boxed cooler will need separate procurement.

Thermal envelope and power

Thermal Design Power and average CPU power are both rated at 80 W, giving a predictable heat load for rack density planning. With no stock fan curve to reference, acoustic output depends entirely on the chosen cooler and chassis airflow design. The 64-bit architecture and integrated DDR3 1866 controller keep platform power draw consistent with the 80 W envelope during typical workloads.

Questions about this item

What is the QPI speed of the Xeon E5-2620 v2 and what does it limit in a dual-socket server?

The processor runs a 7.2 GT/s QPI link, which caps the maximum inter-socket bandwidth between two CPUs in a dual-socket server board.

Which socket and cooler clearance does the IBM 00Y2852 require for installation?

It fits an LGA 771 socket and ships without a heatsink or fan, so a compatible server cooler with LGA 771 mounting holes must be sourced separately.

How is the bare processor installed and what step is commonly missed?

Place the CPU into the LGA 771 socket, close the retention lever, then apply thermal paste before mounting the separate cooler; skipping the paste causes overheating.
