HPE ProLiant DL345 Gen11 Processors

Genuine HPE-qualified AMD EPYC processors for the HPE ProLiant DL345 Gen11, new and refurbished, alongside the heat sink kits they need. This is a single-socket server — one 4th or 5th Generation AMD EPYC processor drives all 12 memory channels and 128 PCIe 5.0 lanes.

DL345 Gen11 Processor Specifications

• Socket: one processor in an LGA 6096-pin SP5 socket — the QuickSpecs instruct you to select one 4th or 5th Generation AMD EPYC processor
• 5th Generation range: the 8-core EPYC 9015 at 125W through the 160-core EPYC 9845 at 390W, every model rated 6400 MT/s memory
• 4th Generation range: the 16-core EPYC 9124 through the 128-core EPYC 9754, every model rated 4800 MT/s memory
• L3 cache: 64MB to 512MB across the 5th Generation list, and 64MB to 1150MB across the 4th Generation list
• Memory support: all 4th and 5th Generation EPYC processors support up to 3TB of memory, 12 channels per processor at 1 DIMM per channel
• Cooling: heat sink and fan kits are selected by processor cTDP — the wattage shown against each SKU is its default cTDP

Order the heat sink with the processor. Up to 240W cTDP takes the 2U Standard Heat Sink and Standard Fan Kit; 260W and above takes the 2U Performance Heat Sink and Performance Fan Kit. With a 4LFF or 8SFF mid tray cage and a processor of 300W or less, it is the 1U Performance Heat Sink instead.

Which heat sink does a DL345 Gen11 processor need?

HPE's processor SKUs ship as the processor alone, so the heat sink is a separate line on the order. The cooling options summary adds a rear-bay rule on top of the cTDP bands: a 4LFF or 2SFF rear cage calls for the Performance Fan kit at any wattage.

Choosing the Right DL345 Gen11 Processor

• A mid tray cage changes the heat sink: with a 4LFF or 8SFF mid tray drive cage and a processor of 300W or less, the 1U Performance Heat Sink and Performance Fan Kit are the required pairing.
• The CPU sets your memory speed: 4th Generation EPYC is rated 4800 MT/s and 5th Generation 6400 MT/s — see DL345 Gen11 memory before you buy kits.
• License-bound workloads: the high-frequency F-series parts, from the 16-core 9175F to the 64-core 9575F, hold clock speed while keeping the licensed core count down.
• Direct liquid cooling exists as cold plate module and quick disconnect tube set kits — a liquid-cooled server ships only as a whole rack.

DL345 Gen11 Processors FAQ

What processors does the HPE ProLiant DL345 Gen11 support?
One 4th or 5th Generation AMD EPYC processor in an LGA 6096-pin SP5 socket. The 5th Generation list runs from the 8-core EPYC 9015 to the 160-core EPYC 9845; the 4th Generation list runs from the 16-core EPYC 9124 to the 128-core EPYC 9754.

Can the DL345 Gen11 take two processors?
No. It is a 1P server - the QuickSpecs instruct you to select one 4th or 5th Generation AMD EPYC processor, and that single CPU provides 12 memory channels and 128 PCIe 5.0 lanes.

Do DL345 Gen11 processors come with heat sinks?
No - the heat sink is a separate kit chosen by processor cTDP. Up to 240W takes the 2U Standard Heat Sink and Standard Fan Kit; 260W and above takes the 2U Performance Heat Sink and Performance Fan Kit.

Which heat sink do I need with a mid tray drive cage?
With a 4LFF or 8SFF mid tray drive cage and a processor of 300W or less, the QuickSpecs require the 1U Performance Heat Sink and the Performance Fan Kit.

Does the processor generation change my memory speed?
Yes. Every 4th Generation EPYC listed for this server is rated 4800 MT/s and every 5th Generation part 6400 MT/s. Both generations support up to 3TB of memory across 12 channels at 1 DIMM per channel.

What is the highest core count in a DL345 Gen11?
160 cores - the 5th Generation EPYC 9845, at 2.1GHz base and 3.7GHz max frequency with a 390W default cTDP. On 4th Generation, the 128-core EPYC 9754 tops the list.
