HPE 461081-001 ML350 G5 System Board

HPE 461081-001 System Board for ProLiant ML350 G5

The HPE 461081-001 is the later system board revision for the ProLiant ML350 G5 tower server. It carries both processor sockets, the eight memory slots and the embedded controllers that the rest of the server plugs into, so a board fault usually takes the whole machine offline.

This revision matters because the ML350 G5 shipped with more than one board over its life. Owners who want to run the later quad-core Xeon 5400 or dual-core 5200 processors, or who have a SATA optical drive fitted, generally need the 461081-001 rather than an earlier board.

We list this part in New and Refurbished condition, subject to stock. Pick the option you want on the product page to see the current condition and warranty details.

Three ML350 G5 Boards: Which One Do You Have?

HPE produced three main system board spares for the ML350 G5, and they are not equal in what they support. An HPE community answer on ML350 G5 processor upgrades sets out the split, and it lines up with the processor list in the server QuickSpecs:

• 413984-001: the early board, for Xeon 5000 and 5100 series dual-core processors, with a PATA optical drive.
• 439399-001: for Xeon 5200, 5300 and 5400 series processors, again with a PATA optical drive.
• 461081-001: covers the Xeon 5000, 5100, 5200, 5300 and 5400 series and uses a SATA optical drive.

The QuickSpecs also warn that some early shipping ML350 G5 models could not take the quad-core upgrade, and that 5100 series models cannot simply move to 5200 series chips. That is why the board part number is the first thing to check before buying processors or a replacement board. The number is printed on a sticker on the board itself.

Processor and Memory Rules for the ML350 G5

The board takes up to two Intel Xeon processors in LGA771 sockets. Depending on the processor fitted, the front side bus runs at 667, 1066 or 1333MHz. The chipset is the Intel 5000Z.

Memory is PC2-5300 fully buffered DIMMs (DDR2-667). There are eight slots, and modules go in identical pairs across slots 1 and 5, 2 and 6, 3 and 7, and 4 and 8. Maximum memory depends on the processor: HPE quotes 16GB with dual-core 5000 and 5100 series chips and 32GB with 5200, 5300 and 5400 series chips. Advanced ECC and online spare memory modes are supported.

Swapping the Board: What Moves Across

A replacement board arrives without processors or memory. During the swap you move these from the failed board:

• Both processors and their heatsinks, with fresh thermal compound
• All FB-DIMM memory modules, keeping the same slot positions
• Any expansion cards and the cache module or battery used by the embedded Smart Array E200i controller

ProLiant service guides of this generation describe re-entering the server serial number and product ID in the ROM-Based Setup Utility (RBSU) after a board change, so note both from the chassis label first. It is also worth checking the system ROM version, and be ready to re-apply network adapter settings in the operating system, as the new board can present the adapters as new devices.

New 461081-001 System Board

Choose the New option if you want a board that has not been fitted to a server before. The condition description and warranty that apply are shown when the option is selected.

Refurbished 461081-001 System Board

The Refurbished option is a previously used board offered as a lower cost way to bring an older ML350 G5 back into service. Check the condition and warranty details displayed for this option before ordering.

461081-001 Technical Specifications

Compatibility

The 461081-001 is a spare for the HPE ProLiant ML350 G5 only. It does not fit the ML350 G6 or later towers, which use different processor sockets and memory. If your server is an ML350p Gen8, look at the HPE 635678-004 ML350p Gen8 system board or the HPE 667253-001 ML350p Gen8 board instead.

How to Confirm You Need 461081-001

• Read the part number from the sticker on your current system board
• Check the processor model in RBSU or on the processor itself, especially if it is a 5200 or 5400 series chip
• Look at the optical drive cable: a SATA drive points to this board revision
• Confirm the server label reads ProLiant ML350 G5

Frequently Asked Questions

Will the 461081-001 run quad-core Xeon 5400 processors?

Yes. This board revision supports the Xeon 5000, 5100, 5200, 5300 and 5400 series, which makes it the most flexible of the ML350 G5 boards.

How is 461081-001 different from 439399-001?

Both support the later Xeon 5200 to 5400 series, but 439399-001 uses a PATA optical drive while 461081-001 uses a SATA optical drive. 461081-001 also covers the early 5000 and 5100 series chips.

Do processors and memory come fitted to the board?

No. The board is supplied on its own, so you move the processors, heatsinks and FB-DIMM memory across from your existing board.

What needs doing after the board is fitted?

Re-enter the server serial number and product ID in RBSU, check the system ROM version, and re-apply any network adapter settings in the operating system if they are lost.

Can I choose New or Refurbished and get it delivered in the UK?

Both options are listed, subject to stock, and the condition and warranty are shown once you select one. UK delivery is available, with options shown at checkout.
