AMD EPYC 7742 64-Core Server Processor
This AMD EPYC 7742 is a 64-core server processor built for the SP3 socket. It operates at a 2.25 GHz base frequency and reaches a 3.4 GHz maximum boost. The chip provides 128 threads and 64 MB of L3 cache within a 225 W TDP envelope. It belongs to the EPYC 7002 series.
Suited for dense compute and memory-heavy workloads
This processor suits deployments needing high core counts and eight-channel DDR4 bandwidth. It also delivers 128 lanes of PCIe 4.0 for extensive I/O. It is not for single-threaded tasks that favour higher per-core clocks. It is also not for platforms that lack SP3 infrastructure or dual-socket support.
The 64-core count and 225 W TDP decide fit
The defining specification is the 64-core configuration paired with a 225 W default TDP. This combination determines whether your cooling and power budget can accommodate the part. Verify that your SP3 platform supports this thermal design before purchase.

คำถามเกี่ยวกับสินค้านี้
What motherboard socket and power budget do I need for the EPYC 7742 64-core 2.25 GHz SP3 225W processor?
The CPU fits Socket SP3 and has a default TDP of 120 W, though the supplier lists a 225 W rating for this unit.
Can I run my existing DDR4 memory with the 7742's 8-channel controller?
Yes, the processor supports 8 channels of DDR4, so compatible DDR4 DIMMs will work at supported speeds.
How do I verify all 64 cores and 128 threads are active after installation?
Check the OS task manager or run lscpu; it should report 64 cores and 128 threads at the 2.25 GHz base frequency.
