Quad-Core Intel® Xeon® Processor 5400 Series TMDG

Note:

In the case of a discrepancy, information in the most recent LGA771 Socket Mechanical Design

Guidelines supersedes that in the Table E-1 above.

E.1.2.2

Recommended Test Sequence

Each test sequence should start with components (i.e. baseboard, heatsink assembly,
etc.) that have not been previously submitted to any reliability testing.

The test sequence should always start with a visual inspection after assembly, and
BIOS/Processor/memory test. The stress test should be then followed by a visual
inspection and then BIOS/Processor/memory test.

E.1.2.3

Post-Test Pass Criteria

The post-test pass criteria are:

1. No significant physical damage to the heatsink and retention hardware.
2. Heatsink remains seated and its bottom remains mated flatly against the IHS

surface. No visible gap between the heatsink base and processor IHS. No visible tilt
of the heatsink with respect to the retention hardware.
