D850GB problems

[austinringding]

I just bought a NIB D850GB on ebay and am having problems getting it to boot up. I am using a P4 1.4ghz CPU that was tested and working.
The RAM doesn't seem to be the problem. I am getting no beep codes and no video but the fans and lights fire up with power. I am using a new ATX power supply, but it does not have the AUX Power connector that this mobo uses. Is that the problem? What does that connector control anyway?

Any and all advice appreciated...

If the mobo doesn't have a new ATX connector for power, then you definitely need to get some AUX adapters or something, they were the old mobo power plug.

i'm not exactly sure I understand you.
the power supply i am using has the 20 pin power connector as well as the 4 pin P4 connector. the connector it doesn't have is the 6 pin AUX power connector that is listed as ITEM K on page 14 of the product manual as seen here: ftp://download.intel.com/support/mother ... 608002.pdf

i was told at Frye's that it shouldn't matter that I didn't have that connector, so I'm wondering if that is true or not.

Is this be the reason that my machine is not booting up?

i believe its a propriatary part. I've seen dell mobos with that type of power connector.





looks like that?

[austinringding]

yep, that's it. none of the power supplies at Frye's Electronics here in austin had that connector and they didn't have any sort of adapter either.

so what's it for, AUX what? and if I don't have that connected, would it cause my machine not to POST?

[The Black Pumpkin]

Oh, I see, I misunderstood you.

I'm not sure what the problem could be then...

[austinringding]

could the fact that I don't have a hard drive attached to the system be my problem? I was getting 3 beeps, and then i realized I had the RIMMs installed in the wrong slots so I moved them to RIMM1 and RIMM2 and the beep code went away. Now like I said the fans and lights go on, no beep codes but I get no video.

I've tried AGP and PCI video cards.

thanks for the help

no the issue is that your mobo is a propriatary part, meaning that is specially built for a certain company.

dell is known to have those type of connectors i recommend u dont go thru the hassle and just just get a new mobo, socket 478's are cheap.

finding a PSU that powers that is a pain

[austinringding]

ok, here's the deal. i do have a power supply with that connector, but it wasn't seeming to work properly. how can i test it with a multimeter to see if it is indeed pumping out the proper power?

I'm not sure how much of the manual you read, but if you read the section on the motherboard memory it states that if you don't have ALL FOUR RIMMS filled or have blanks in the two extra slots that you're not using then computer will not boot. It's on page 20, section 1.5.
Hope that helps

he means DIMM's not RIMM's

Nope.....he means RIMMS --> Rambus inline memory modules!

With RDram you need to fill all slots....if you have two sticks, then you need to use blank RIMMS to full the empty slots...."old school dual channel"
