Moca-ar HP ITX MoDT Board Issues

[cyborg28]

Hi Everyone,

I'm new here, but I know there is some experience with this board on the forum so I'm posting a plea for help!

I wanted to do a cheap ITX build that will run a GFX card and be faster than Atom.

Found this board on ebay:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c00783647 And got some parts to fit it out.

Power Adaptor for MINI 24 pin ATX
http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=130490786047&ssPageName=STRK:MEWNX:IT

An ITX case w/200w PSU, Intel T7300 Core2Duo Mobile, DDR2 Sodimms.


But I cant get the d*mn thing to boot. When I power up the CPU fan spins and nothing else. No video output to the vga, no beeps from the onboard speaker.

Has any one had similar experience. I have tried two different moca-ar boards from the same seller, both do the same thing. I have also tried it with a Pentium Dual Core T3200, with the same result.

Thanks for your help,

are you sure the pinout between your power supply and the mobo is correct on the power cable? i think i read somewhere that hp and dell use a proprietary pinout on their power connectors on some boards.

Hi,

Thanks for the response.

I think the power pinout is ok. I have been in touch with other moca-ar users and they say the pinout is standard ATX 12v 24 pin, just a mini molex connector. I have verified the pinout with a multi-meter.

Cheers,

ok, that was my only guess.

I was going to grab one of those as I've got a dual core cpu, memory, etc that would work with it, but the power supply deal scared me off.

I'd be interested in what the solution to the problem isq. Sounds like a power issue to me. Have you tried a different power supply with it?

"The Pentium T3200 and Core2Duo 7300 are socket P where you need socket M cpus.

Basically fully supported CPUs in the T7 line would be T7200,7400,7600"

All I can say is F*cking Intel! Two cpus that are named in series, T7200 and T7300 and have an almost identical and totally interchangeable pin layout require two different and incompatible sockets. There is no logic in this!!!!

Power is no problem Just need one of these:

Just be sure your CPU is SOCKET M not socket P.

And Socket M procys are dang expensive.

Dual 2.0GHz@~$200!
I'd like an upgrade, but not that badly!
