You're correct, but the HP site you listed says DDR3 in more
than one place. So head over to Newegg and have a look at
the reviews.
http://www.newegg.com/Store/Category.aspx?Category=20&name=Motherboards
I think it's DDR2.
HP Pavilion Media Center m8530f
http://h10025.www1.hp.com/ewfrf/wc/...&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN#N79
M2N78-LA
Processor socket: AM2+
Memory sockets: 4 x DDR2
We can also look up the processor (Phenom X4 9550).
That's the fixed version of the 9500 without the TLB bug.

Socket AM2+
http://www.cpu-world.com/CPUs/K10/AMD-Phenom X4 9550 - HD9550WCJ4BGH (HD9550WCGHBOX).html
On-chip peripherals
Integrated dual-channel 144-bit DDR2 SDRAM Memory controller
So an AM2+ motherboard would be a good start.
*******
By comparison, if we look at a recent high end AMD, an AM3, this
is what it lists for the memory controller.
http://www.cpu-world.com/CPUs/K10/A... Edition - HDT90ZFBK6DGR (HDT90ZFBGRBOX).html
On-chip peripherals
Integrated DDR2/DDR3 Memory Controller
So an AM3 supports DDR2 or DDR3 (the motherboard design picks the type).
An AM2+ has a DDR2 controller on it, with the memory type fixed at DDR2.
*******
To find a motherboard quickly, you can use the Asus search engine, entering
the 9550 as the processor type. This is the CPU Support chart page.

Not all of those are MicroATX sized. Some are full sized. In
any case, none are for sale on Newegg.
So far, I ended up on Amazon.com , and this is the
first one that comes close. I'm not a big fan of Biostar,
due to their habit of connecting ATX12V to the 12V wire on
the main power connector.

Chipset AMD 780G / SB700
STORAGE
6 x SATA2 3Gb/s Connector
1 x IDE Connector
http://en.wikipedia.org/wiki/AMD_700_chipset_series
SB700
Support up to 6 SATA 3.0 Gbit/s hard disk drives
1 x IDE connector supporting ATA-133/100/66/33 and
up to 2 IDE devices
There is *no* floppy connector.
The add-in slot mix is different than your current motherboard.
The Biostar has a couple PCI slots, instead of your previous
PCI Express x1 slots. Whether this is important or not,
will depend on what add-in cards (TV tuner etc) you have
in the PC.
This is the rear I/O area.

There is at least some risk, that the PANEL header pinout,
will be different than your "Viola" motherboard. Check the
manual. (This is a self extracting RAR with PDF inside.)
The PANEL wiring is on page 14. The SPKR is a 1x4. Your
PC doesn't have a beeper speaker. With the new motherboard,
there will be "nothing to beep", as your "Viola" had the
speaker onboard. The PWR LED connector can span two or three pins,
and in the three pin case, the wires would be on pins 1 and 3.
Your "Viola" motherboard, looks to be a 2x4+1 header, so probably
up to four 1x2 connectors.

Now, the weirdest part, is the 9550 isn't in the CPU Support chart!
How did they miss that ? There is one 125W processor in the chart,
which means the motherboard can handle up to a 125W processor.
The 9550 is 95W, so it's not bumping its head on a power limit.
http://www.biostar.com.tw/app/en/mb/cpu_support.php?S_ID=344
The funny thing is, Tigerdirect was bundling the 9550 processor,
with that motherboard. So it can't be that non-compatible.

Anyway, good luck in your hunt. The pickings are pretty thin.
