Phoenix: Signal-level testing for DDR3, DDR4, and DDR5 memory
Phoenix talks to memory modules directly through FPGA hardware instead of a host motherboard, exposing the intermittent, power, and bus-level faults that host-based testers let through.
Most DDR testers run host-based checks: plug in the module, check that it boots, call it good. Intermittent failures slip through and those modules go back into service.
Phoenix was built to catch what host testers miss, using FPGA-driven electrical diagnostics and real-time signal analysis on DDR3, DDR4, and DDR5 modules.
System-level emulation hides critical issues:
Intermittent failures pass unchallenged
Modules with marginal signal quality pass functional tests, then fail under real load
Power and bus-level issues stay invisible
Traditional testers rely on motherboard chipsets that mask electrical faults. Phoenix communicates with the module at signal level, so intermittent failures, power anomalies, and bus errors surface. Modules it validates hold up in high-stress environments where host-tested modules fail.
JEDEC-compliant protocols Electrical specifications and full timing verification for DDR3, DDR4, and DDR5.
Signal integrity Eye diagram analysis and jitter measurement against data center requirements.
Phoenix tests up to 10 modules at a time in any mix of DDR3, DDR4, and DDR5 at up to 4,400 MT/s. Swapping a color-coded quick-exchange adapter changes module type: green for DDR3, blue for DDR4, red for DDR5. Modules hot-swap without interrupting other slots.
It runs in our facilities in Penang, Bydgoszcz, and Hayward, at select partner sites, and in rack-mounted systems for on-site testing.
How Phoenix works
Load
01
Up to 10 DIMMs go in at once for parallel testing.
Test at signal level
02
FPGA boards drive electrical-level tests with 17 selectable algorithms, including March C-, March SR, and Rowhammer. Test type and sequence are set per slot, with stop-on-failure for fast triage.
Report
03
Every result is serialized and passed to enterprise systems through standard APIs, with no manual steps.
Recover components
04
Failed modules go to Maya and Bujang for chip-level recovery instead of scrap.
Common questions
Can Phoenix find faults our current testers miss?
Yes. It tests at signal level, exposing failures host-based systems cannot see.
Does Phoenix support DDR5?
Yes. It supports DDR3, DDR4, and DDR5, and can test a mix of all three at once using quick-exchange adapters.
Can I buy Phoenix?
No. Phoenix is proprietary infrastructure that runs inside our operations and select partner facilities.
Can it be deployed in the field?
Yes. Rack-mounted and mobile configurations allow testing at customer and data center sites.
