Will motherboard made of same chipsets support same CPUs?

Hi All,
I have a HP ML110 G4 which I use as workstation, it came with a Pentium D 2.8GHZ CPU and I would like to upgrade the cpu so I can use Hyper-V.

I did some search and notice that from HP docs, it says:
Supported CPU: (source 1)
Processor:
Dual-Core Intel® Xeon® processors 3000 sequence; Dual-Core Intel® Pentium® D processors 800 or 900 sequence; Single-Core Intel® Celeron® D processors

source 2:
Supported CPU's in the ML110 G4
Dual-Core Intel® Pentium® D Processor 945 (3.4 GHz, 800 MHz FSB)*
Dual-Core Intel® Pentium® D Processor 935 (3.2 GHz, 800 MHz FSB)*
Dual-Core Intel® Pentium® D processor 925 (3.0 GHz, 800MHz, FSB)
Dual-Core Intel® Pentium® D processor 915 (2.8 GHz, 800MHz FSB)
Dual-Core Intel® Pentium® D processor 820 (2.8 GHz, 800MHz FSB)*
Dual-Core Intel® Xeon® processor 3050 (2.13 GHz, 1066MHz FSB)**HT
Dual-Core Intel® Xeon® processor 3040 (1.86 GHz, 1066MHz FSB)
Single-Core Intel® Celeron® D processor 352 (3.20 GHz, 533MHz FSB)*

So it looks like the xeon 3040 or 3050 could be the only choice.

I also found out that the chipsets used in the motherboard are as following:
North bridge Intel 3000
South bridge Intel ICH7R

further digging into this reveal that similar motherboards that use the same chipsets are capable of supporting xeon 3200 quad-core CPUs!

the following two are the examples:

Intel Entry Server Board S3000AH
SuperMicro PDSML-LN2+

I am not a hardware guru thus I would like to ask for help here.

Can anyone possiblly tell me that whether the motherboards made of same chipsets will support same CPUs? In my case, will a xeon quad-core X3220 fit into the HP ML110 G4 machine?
Thanks in advance and I do appreciate any help.
