Product Overview
The Dummy CPU (DC-A-SP7) is a purpose-built module that physically replaces an AMD SP7 CPU during motherboard testing. It matches the real CPU’s footprint exactly, so it drops into existing sockets and fixtures without modification, while bypassing the BMC power-on sequence entirely. Its built-in self-check verifies crimping status, supply voltage, and crystal oscillator health before testing even begins, and it plugs directly into Telebyte’s cable-free K1149 ecosystem for full-speed differential signal testing.

Traditional vs. Dummy CPU Testing
Traditional Setup
Cable-based wiring for standard cards
Manual fixture verification
Requires BMC, PDB, FAN boards
Complex needle-plate fixtures
Standard power-on sequence
No auxiliary components required in the test environment
Dummy CPU + Traditional Setup
Cable-free operation
Automatic reliability self-test
No auxiliary hardware needed
Simplified fixture design
No BSDL file required
Boosted test efficiency, faster power-on
For SLIM/MICO connectors without integrated power definition, an external power/ground supply to the dummy card is required to maintain signal integrity during testing.
Telebyte vs. Others
Each dimension is scored on a comparable basis, with the optimal value set at 100.
•
No CPU power-on initialization needed
•
No auxiliary components required in the test environment
•
Supports added interface coverage for power-on companion parts
•
Detects peripheral signal defects other fixtures miss
•
Unaffected by CPU supply availability across the product lifecycle
•
Fixture delivery lead time is controllable, independent of BSDL accuracy

Success Story
Dummy CPU Solution
Catches fixture defects legacy testing misses.
The Dummy CPU monitors peripheral ground and power signals on the CPU dummy itself, catching fixture pressing-fit defects that standard test setups miss entirely. Its dedicated boundary-scan chain also cuts the number of test probe pins required versus legacy BSI fixtures, so fixtures stay simpler to build and maintain over the product’s full manufacturing lifecycle.
