ML350 G6 cpu support, in need of explanation

[Slider82]

Hi all,

I want to upgrade my old ML350 G6, I love those era CPU's. Also still use my trusty i7 920.
It has the 511775-001 rev 0B motherboard.
I have searched for weeks to find the details about the different motherboards, these ML350 G6 came with.

People say:
- 511775-001: Only supports X5500 series.

- 606019-001: Supports X5500 and X5600 series.

But I can'tfind any proof why this should be the case!
In old posts I found this link, which was given as proof:

But still I can't read anything on the limitations of the older motherboard.

There are even 511775-001 Rev 0A and 0B boards, no idea what differences they have.
Also I have given the ML350 the latest system rom

2015.08.16(30 Sep 2015)
Many version ealier the support for X5600 was added.
The Intel 5520 chipset also supports X5600.

So why should a 511775-001 Rev 0B not support X5600 CPU's?

Since nobody seems to know this, I tested my theory myself.

I bought an E5620 second hand and it works perfectly with my 511775-001 rev. 0B
So don't trust the other sheep on the internet claiming that motherboard version does not support X5600 series.
Just update the bios, can still be done with a Service Pack dvd.

The latest bios for the ML350 G6 is the 2015.08.16 (30 Sep 2015) which is for example stored inside the Service Pack for ProLiant version 2017.04.0 (<871795_001_spp-2017.04.0-SPP2017040.2017_0420.14.iso>/hp/swpackages/cp028200.exe).

However you need a working support contract with HP in order to download the latest SPP (if you do not find that or the file somewhere via google).
