I currently have a DL380 G5 with a dual core CPU. I wanted to find out if I can upgrade it to two quad core CPUs.
The S/N is XXXXXXXXXX
P.S. For your security, I have removed the serial number from your post - that's information you probably don't want to make publicly available. - HP Forum Moderator

Based on the Partsurfer lookup, there is no way to determine exactly whether your system board would support the Quad Core CPU's. I looked up your serial number in the HP Warranty database and it appears your server was produced in 2007 - and likely would not support the Quad Core CPU's.
The only way you can really know whether your system is upgradeable would be to look at the spare part number on the system board serial number tag.
Here are the two possibilities:
407749-001: System (processor) board - With processor cage and battery - For use with Intel Xeon 50xx and 51xx dual core processors
436526-001: I/O systemboard (mother board) - Supports Intel Xeon 50xx, 51xx, 52xx, 53xx and 54xx processors (quad-core) - Includes cage and battery - Quad-core processors or dual-core processors can be installed on the system board
Hope this info helps.

I have opened the box and tried to locate the S/N on the system board. However, I am not able to find it.
The system board is a very cluttered place. Where should I look?

You may need to remove the PCI card cage. The sticker with the system board serial number and part number is usually placed underneath the area directly below the card cage. If you have any cards installed, it would block your view.

Thanks much for the useful info!
I opened the box and removed the PCI cage. I found a label that says
Is this a good sign? :)

You are in luck! A Partsurfer lookup o that spare part number says that it can be upgraded to Quad Core CPU's - 436526-001: I/O systemboard (mother board) - Supports Intel Xeon 50xx, 51xx, 52xx, 53xx and 54xx processors (quad-core) - Includes cage and battery - Quad-core processors or dual-core processors can be installed on the system board.

I am thinking about DIY. I figure I need an identical pair of refurbished Xeon E5405 - 2.0GHz CPU kits, that includes the PROCESSOR, HEATSINK, AND VRM, designed for HP DL380G5.
Anything I should take caution?
Thanks again, Jeff

Currently I am looking at 458579-B21 but I want to make sure I can install two of them onto the system board. As mentioned in the previous postings, my system board has a part number 436526-001. This part number does support quad core processors and there are two processor sockets on the board.
My question is, can I install two 458579-B21 processors? Are there any restrictions on how many (one or two) of them being installed?
This may be a stupid question, but I am a newbie and please help me.

I purchased two refurbished E5405 Quadcore kits (458579-B21), with heatsink and VRM.
But I just discovered that I can only install one processor (with heatsink and VRM) to my DL380 G5. I have installed either of them and been able to boot up.
However, I am not able to boot up when both processors (with heatsink and VRM) are installed. The server seems to try to boot again and again, with fans starts to spin, etc., but it never starts up.
Obviously, the processors are good, otherwise I wouldn't be able to boot up with each one of them individually.
Is there any BIOS configuration that I have to set so that the server works with two processors?

When I tried putting either processors into the first CPU socket, I had the good VRM in the slot so it worked with either processors.
I realized that I should test out the VRM, so I swapped the other VRM into the first slot, neither processor works. So the culprit is really the VRM.

If I buy processor can I use existing vrm or I have to buy new one.
What is the latest processor I can upgrade to.
I am attaching a picture of motherboard for reference.
