Question Galaxy MCP73PV motherboard: Connectors?


Just bought one of these motherboards (also named IN73M-PVAOGH2LF), but reseller didn't supply a manual. Nothing is printed on PCB, indicating connector functionality, so i'm looking for info on stuff like power switch and HDD-led connector placement.

Anyone?

Facts:
Socket 775, DDR2-6400 (2 modules), onboard nVidia 7100/nForce630i

Hi

I've done a quick bit of research on this motherboard, and I can see what you are up against.

Description and basic specs:
http://www.galaxytech.com/japan/Prod...ils.asp?id=155

Manufacture's site appears to be "www.galaxytech.com". Which isn't very useful site, no sign of a download link for a manual or drivers that I can see ("English" (? lol) version or site)

You could try emailing them at: support@galaxytech.com according to their contact details page. But given the mix of Chinese and English on the site that might be a problem.

The other way would be to reverse engineer the header, either by eye or using a multimeter.
Draw a diagram of the pins. Look for all the pins connect to a common ground. The speaker is usually a group of four pins +..- or vice versa. You should be able to make a good guess at the pins from there. ***But do so at your own risk***

In the meantime I'll keep a lookout for any documentation that comes up, and post here if I come across any.

Hope that helps

Regards

Chris

It appears to have been offered as three builds:

Galaxy MCP73U GeForce 7150 / NVIDIA nForce 630i
Galaxy MCP73PV GeForce 7100 / NVIDIA nForce 630i
Galaxy MCP73V GeForce 7050 / NVIDIA nForce 610i

Looking for those ....

MCP73PV motherboards were used as a component in a series of Acer PC's - but no luck on the documentation front there

If what I'm looking at in these pictures, comparing it to the homepage link given in the second post above, It also appears to be used as the mother board in an HTPC sold in China. There, it's known as the PV7100, or "model 202150".

I have found lots of info about it, including download link(s) for what's supposed to be the manual, though probably in Chinese too, but I couldn't get anything to download. Not sure why..

Here's some links anyhow; and Google translate-webpage does a half decent job with them (only half decent)..

http://diy.pconline.com.cn/guide/gdd...1182226_2.html
http://product.pconline.com.cn/pdlib...1209.html#id=0
http://product.pconline.com.cn/mb/galaxy/202150.html
http://diy.pconline.com.cn/main/hq/gz/0710/1133351.html

Best of luck.

FWIW, the fan connectors, storage connectors, power conns, PCI conns, all the usual stuff are fairly obvious; if the power, HDD LED, and those sort of connectors are the main questions, I **think** they are **somewhat** standard too-- at least the audio connector is-- so have a look around at other board images that ARE labelled, and maybe see if the various front-panel connectors tend to follow any sort of standard..

Thumbs up

@cgtueno:
Yup - i was almost about to remove the motherboard from its casing and start reverse-engineering the thing. But luckily i'd also done just as you suggested; sent them an email requesting assistance.

And i got a reply... In perfect english, polite and businesslike - and containing a large and well-done manual in PDF-format. I'll post a link to it here when i get home from work, so that others can have access to the manual.

Yes, this motherboard comes in three variants. I put my hands on the 7100-version for just $20 as whitebox-product.

@GrapefruiTgirl:
Thanks for your effort in helping me out.


Posting questions on LQ once more proves to be a positive experience.

Thanks, all

Cool by at $20
I oticed that there were lots of references to it as a OEM supplied motherboard for brandname computers at one stage (allbeit for machines that I had not periously heard of)

I'm really pleased that you got hold of the information

And I shall eat humble pie about my cynical expectations about a reply from their technical support people. But I did base it on my experience of their website.

Would be great if you put up a link to the PDF sometime.
One less motherboard to chase down.

Oh - Did they forward you a CD of drivers ? Or did you have that already in the box ?

Best regards

Chris

Good on you

How did you connect the MCP73PV with the PV7100/"model 202150" during your searching ?
Keenly interested to know.

I started with the image of the board at the website cgtueno linked here: http://www.galaxytech.com/japan/Prod...ils.asp?id=155
.. and then searched "Google-Images" for pictures of "MCP73V"

There are/were matching, identical images of the same board at several locations. The most relevant ones were from sites in Denmark, and China.
Following the Danish links, I mostly found people like the OP, who had such a board but no manual. The Chinese links though, seemed to be much closer to where the board actually came from, and could be purchased new.
It is a whitebox product in a lot of locations, but in China, it can be bought new off the shelf in a "colored-box"

@everyone:

Manual uploaded to drop.io. Try following this link:

http://drop.io/hidden/udujadpycqq92o...VhbC1wZGY%253D

@cgtueno:
No driver-CD forwarded. No CD in the box. Hopefully no problem.

@GrapefruiTgirl:
Via 'Google Images'? Cool! I've never thought of going that way


Actually, i've already half-way-installed an OEM XP onto the board yesterday evening. Didn't complete the install for two reasons; I was short on time and installing XP is a very time-consuming, awkward, silly and stressing process.
Yes, I know... But the thing is destined for playing Call of Duty: Modern Warfare 2. No idea in using any sort of Linux on a dedicated gaming rig. Really, 3D FPS-games == Windows.

In case of trouble, I'll run e.g. Ubuntu LiveCD on the board and see what it finds

Complete machine will replace an AMD64/3000 setup my son is using today for CoD:MW2 etc., hopefully boosting game experience even further.

BTW i can recommend CoD:MW2. Fantastic storyline, very diverse tasks/quests, all the right features and finally - graphics so stunningly beautiful, i constantly have to remind myself this is not 'real' when watching the kiddo hammer baddies into oblivion. Mind-boggling!

It definitely does look like a great deal at $20.00 as it appears to be a well-equipped board.

One suggestion, in case it interests you: if/when you decide you may want to load a LiveCD to learn more about the board, like if you have trouble with some hardware, Ubuntu is probably a good choice, as it recognizes a lot of hardware; but also, don't forget Knoppix -- Knoppix is renowned for its hardware identification abilities, and is a little bit 'lighter' than Ubuntu as well.

Best of success with the project -- keep us posted

Agrees with GrapefruiTgirl: Knoppix would be a great live Distro for system exploration.

Hmmm... I'll keep an eye out for a Driver CD for the motherboard, and post here if I come across one. I imagine that there would be one, perhaps a followup email to the manufactuer (never know your luck) ?

Given that the board was OEM - was there a custom BIOS on the motherboard (ie branded for a specific manufacturer ? Or does it have generic BIOS ? - Just curious about where it was originally intended to go as an OEM board)


GrapefruiTgirl

Thanks for the reply Sasha. Interesting approach working by images (smiles).
Wouldn't have thought of using that to establish other alias' for a motherboard.

My search experience matched yours on the whole, lots of references to people in mafiltenborg's situation (ie. have the motherboard but no documentation), and I found plenty of references to large PC builders/retailers ordering the motherboard as a system.

The images I encountered in Google we nearly all photos on hardware seller sites. Didn't find a reference to this series of motherboards being sold in retail packs, just OEM.


mafiltenborg & GrapefruiTgirl

I find it terrible that manufactures with product specific webpages don't setup downloads for their product documentation. Especially since the product documentation is pretty much useless unless you have acquired the hardware.

It's worse still when the manufacturer supplies a major company with modified or "feature stripped" motherboards but maintains the same model number for the motherboard. (Shrugs his shoulders). without a record of the variations it causes all sorts of problems for end users.

Hopefully things will improve with time. (Crosses fingers).

@GrapefruiTgirl:
Hehe - actually the price was even lower: USD 19.12 using today's exchange rate.

@cgtueno:
Driver CD? Dunno - i feel no need for that. Board appears to work nicely.
Will check BIOS implementation. It appears to be feature-packed; e.g. support for OC is present - lots of little handles and knobs to pull, turn and tweak. But read on...


Next, addressing a completely different issue; reducing the sound level from attached CPU fan. Now, it reminds me of a vacuum cleaner: LOUD!

80 mm fan runs flat out, full throttle. It draws around 8 Watt, runs at 4300+ rpm and is clearly out of sync with real-world-requirements for airflow. BIOS appears to have management features which i've enabled, but clearly they're not working. Oh well; nothing that can't be cured with a suitable series-resistor.

I've wondered if it was the fan/heatsink that was wrong, but it's a standard LGA775-thing with tacho - which works allright. BIOS displays the RPM in real-time.

In general, this board seems to be sub-standard. E.g. the CPU heatsink mount (using a metal X on PCB backside) cannot be installed without adding washers to raise it 2 mm above PCB surface; some genius decided to put a few SMD-components there, and the metal X is designed to be in contact with PCB, meaning that the SMD's will be crushed unless i add (nonconductive) washers.
Adding washers solves that issue, only to create another: Metal X now protrudes from PCB backside, getting in contact with cabinet, causing PCB to be not fully rested on cabinet mounting threads. Bugger!
BIOS fan management seems broken.
Manufacturer manual support sub-standard.
Updated BIOS'es available, but poorly made; three versions, all released on the same day, providing an odd mix of 'new features', like no support for P4, RAID/!RAID. Hmmmm...

But - the design runs like a charm. Especially the nForce 630i/7100 combo hits home. Installed the nvidia driverpackage, and GUI went ballistic. Next, I'll try pushing the onboard GPU a bit before installing Radeon4670. Just to see what onboard graphics can do, when it's not from Intel (Curse 945, curse 915, curse 810, curse Intel onboard GPUs in general, curse curse curse...)

Amongst the links I posted (or if not one of those, I'll find it again) there's a review of the product (or a product *containing* this board, but I think it ws the board itself) which was pretty much identical to the sort of review one would read on Tom's hardware -- a 5 or 6 page review of the board, showing off its chipset, BIOS features, etc.. In that article, it was an Award BIOS, and in the pictures, it didn't seem to be customized to any particular OEM, but rather looked like a normal, decent BIOS, with OC features, and also there is/was RAID onboard and IIRC controllable by the BIOS. They also showed using the software OC tool from Windows, to tweak and tune the thing, and the review was favorable of the whole thing.

If you're interested, I'll find the article again for you (it was in English I think, but I can't recall if that's because I translated it, or because it was English to begin with.)

As for the CPU fan -- 4800 RPM is pretty ridiculous IMHO for a CPU fan. Mine (on my 775 Intel Core2) runs at a max of about 3000 RPM or so at full throttle, but I usually run it somewhere between 1200 and 2000. It's temperature-controllable by BIOS settings, with settable trip-points based on temperature. Sounds like the one you have there is comparable to the junk one that comes with my MSI board's northbridge cooler (I didn't get that model) which goes like 10000 RPM and drives people mad. You might consider a new cooler/fan combo
Also, IIRC, I saw 3 fan connectors on that board (I didn't look that close) but not all of them are necessarily PCM controllable (temperature-controllable by BIOS). My MSI board has 4 fan connectors including the CPU, but only 3 of them are variable including the CPU fan; the 4th is "On or Off (or actually, probably just "on")", so on your board, it'd be reasonable to presume that maybe only the CPU, plus at least one other of you're lucky, is adjustable.

As for a driver disk, again, the Chinese sites I found showed the retail package of the board, in a non-white-box, and it included some SATA wires, a manual, and a Driver disc, among other things. You're probably right in that you can do without the driver disc, but it would be nice just to know what's on it.

Anyhow, again: if you want me to find any of the particular pages I did find, again, just ask.

Best of luck,

Sasha
