FAQs

Q: How does the 6140M differ from the 6140?
A: Performance characteristics are similar; the M version enables up to 1.5 TB memory per socket depending on platform support.

Q: Do I need special memory for the M SKU?
A: Use platform-qualified high-capacity ECC RDIMM/LRDIMM modules; verify your server’s memory population rules.

Q: Is firmware validation required for the M variant?
A: Yes, ensure your server BIOS/firmware supports 6140M and the increased memory capacity.

Q: Can I mix M and non-M CPUs in dual-socket systems?
A: No. Dual-socket configurations should use the same CPU model; mixing M and non-M is not supported.

Q: Does it support AVX-512 and virtualization?
A: Yes, it supports AVX-512 as well as VT-x/VT-d for virtualization acceleration.
