Technical Specifications

FAQs

Q: Is this riser compatible with C240 M5 T4 systems?
A: Yes, it is designed for T4-class C240 M5 configurations using the 1B riser position.

Q: Does this riser support GPUs?
A: For GPU acceleration, use a riser variant that explicitly lists GPU support such as 2A or 2B.

Q: What happens if only one CPU is installed?
A: Because all slots on this riser are sourced from CPU1, they remain active when only CPU1 is populated.

Q: Are the slots backward compatible with PCIe Gen2/Gen1 cards?
A: Yes, PCIe is backward compatible; Gen2/Gen1 cards are supported at their native speeds.
