Thanks Paul,
For correcting my mistake.
But an mATX will not work for me. I have PCI devices and a 400W power
supply. I have 8GB DDR2 RAM in two modules. An ATX MOBO with four DIMM
slots would support dual channel memory. Here's one for your comment:
ASUS P5QD TURBO LGA775 Socket ATX DDR2 P45 motherboard dual PCI Q9650
https://www.ebay.com/itm/ASUS-P5QD-T...-/303209371562
It is refurbished but it is cheap. Can you suggest anything related?
Thanks.
The board in your Ebay entry is missing the Northbridge heatsink.
In this picture of the same board, you can see the heatsink
in the picture. It's not a 40mm heatsink either, and the retainers
are weird looking (probably not fun to find a replacement).

There's a similar one on this side of the Atlantic, but that's
probably not going to help you. This is a P43 based board.
Actually, it's pretty hard to tell exactly where this
seller is located, as the delivery date is all wrong for
a seller here.

I tried ebay.de and the pickings were pretty slim. Lots
of BTX boards nobody is going to be able to use and so on.

I have ordered an Intel Q9650 CPU cooler. The old cooler was party to the
death of my motherboard. Its bearings failed and vibrated, inducing
sympathetic (harmonics) throughout the frame.. Q9650 needs TPI of 95W. I was
getting kernel events regarding temperature induced slow down with my bad
CPU cooler.
What do you think of this MOBO? :

Its a good price, good features, good peripherals. It seems to be related to
other MOBOs on that page. Its dimensions do not conform to ATX or
derivatives. My question is if the holes for mounting screws would line up
with my ATX? Then I can keep the case, PSU, CPU, 8GB DDR2 RAM, SSDs, etc.
Thanks.
Is that three phase power ?
The advert claims it has a UEFI BIOS. Which implies a later
date of manufacture than original LGA775 motherboards.
Notice there is no branding printed in white on the motherboard,
similar to what you'd find with a PCChips motherboard.
The lineage is important. We need to see a "CPU Support" chart,
to make sure the Q9650 has sufficient power, and the three phase
power won't overheat. You can get about 33W per phase, for a
Richtek design. Many other setups, the phases are designed for less
power each, and there are more phases to compensate. To drive
more power, may require MOSFETs with higher gate capacitance,
which benefits from 8 pin buffer chips per power phase. (If
you don't buffer up the phases, the main regulator chip gets
too hot. The gate capacitance is around 3000pF. On a RichTek, the
frequency it switches at is relatively low compared to some
of the others. The others may have better transient response.)
It helps, with any motherboard, to have people saying they
didn't have trouble getting the "top" processor in the line,
to work on it. That's why I would prefer to track down the
branding, if I could figure it out.
The same motherboard. These adverts keep saying SATA III,
which is unlikely.
"4 x SATA3 Connector (3GB/s)" No! 3Gbit/sec is SATA II, consistent with LGA775
It's more likely a SATA II board.
This lists DDR3 slots in this advert. Obviously,
you just sling in bull****, when writing adverts.
What fun!

Here's another advert. In this one, the motherboard model is "V7R8" and not "M2O6".
https://www.ebay.co.uk/itm/Motherboa...-/113781756709
"Brand: Unbranded/Generic"
The adverts also say:
1 x PCI-E 2.0 x 16 Slot
1 x PCI-E x 1 Slot === looks "PCI" to me
I've been using the ASIN number to track these.
On this one, the sticker next to the DIMM slots,
looks to be Chinese.

I wish they would identify the NIC chip.
I would not want to discover it was the PCI one.
