HPE ProLiant SL4545 G7 Processors

Genuine HPE processor option kits for the HPE ProLiant SL4545 G7, new and refurbished. Each server node in the chassis takes up to two AMD Opteron 4200 series processors, and HPE does not support mixing different processor models — so the second socket has to match the first, node by node.

SL4545 G7 Processor Specifications

• Sockets: two per server node, on the AMD SR5690 chipset reference design, upgradeable to two processors
• Eight-core kits: AMD Opteron 4284 at 3.0GHz and 95W, and the 4274 HE at 2.5GHz and 65W
• Six-core kits: AMD Opteron 4238 at 3.3GHz and 95W, and the 4226 at 2.7GHz and 95W
• Cache: 8MB of level 3 cache per socket, the same on all four kits
• Memory speed: all four support DDR3 up to 1600MHz, with the speed actually reached depending on the quantity and type of DIMMs installed
• Kit contents: every processor kit comes complete with heatsink and fans; HPE's configurator pairs one -L21 option with a matching -B21 kit where a node is being built with two processors

The second socket has to match the first, and it does more than add cores. HPE does not support mixing different processor models in one server, so an upgrade to two processors is two of the same kit. Six of a node's twelve DIMM slots are dedicated to each socket, which makes the second processor the thing that opens the rest of the 192GB.

Eight Cores or Six, and at What Wattage?

All four carry the same 8MB of level 3 cache and the same 1600MHz memory ceiling, which leaves cores, clock and watts as the whole decision. The 4238 holds the highest clock, the 4284 the most cores, and the 4274 HE is the only part under 95W — which matters more here than on a standalone server, because one set of chassis supplies carries every node.

Choosing the Right SL4545 G7 Processor

• Both sockets in a node must carry the same part. HPE does not support mixing different processor models, so adding a second processor means a matching kit rather than a better one.
• The second processor opens the other six DIMM slots. Six of a node's twelve slots are dedicated to each socket, so a single-processor node reaches half the 192GB ceiling whatever modules are fitted.
• Buy per node, not per chassis. A 3x15 chassis holds three independent two-socket servers, and each is configured on its own.
• Watch the chassis power budget rather than the node's. One set of Common Slot supplies feeds every node, so three nodes of 95W parts is a very different draw from three of the 65W 4274 HE.
• The kits arrive complete. Heatsink and fans are in the box, so no separate thermal kit is needed alongside them.

Complete Your SL4545 G7 Build

The second processor is what opens the rest of the memory — see SL4545 G7 memory — and the chassis supplies carry every node, so check SL4545 G7 power supplies before a wattage step up.

SL4545 G7 Processors FAQ

Which processors does the SL4545 G7 support?
AMD Opteron 4200 series, up to two per server node. The eight-core options are the 4284 at 3.0GHz and the 4274 HE at 2.5GHz; the six-core options are the 4238 at 3.3GHz and the 4226 at 2.7GHz.

Can I mix processor models in one SL4545 G7 node?
No. HPE states that mixing different processor models is not supported, so both sockets in a node must carry the same part.

Why do the processor kits say Gen8 when the server is a G7?
That is HPE's own naming. The QuickSpecs for the SL4545 G7 lists these kits as SL4545 Gen8 parts, so a kit labelled that way is the correct processor for this server rather than a part from another model.

What does a second processor add besides cores?
Six more DIMM slots. Each socket has six of the node's twelve slots dedicated to it, so the second processor is what opens the rest of the memory capacity.

Do SL4545 G7 processor kits include a heatsink?
Yes. Every processor kit listed for this server comes complete with heatsink and fans.

What memory speed do these processors support?
Up to 1600MHz DDR3 on all four kits. HPE notes the speed actually reached depends on the quantity and type of DIMMs installed, and every memory option listed for this server is rated DDR3-1333.
