Asus P7p55d deluxe motherboard

Specs: none yet
I just put together my new pc yesterday and when i booted it up there was a loud continuous beep coming from the mobo.
My guess is that i conected the vid card power incorrectly or i have insufficient wattage on my pwr supply.
A friend of mine suggested that it can't be the vid card because i havnt installed the drivers or the OS yet...he thinks i have incompatible ram. (2, 4g sticks of DDR3)
Can anyone confirm, deny or help in any other way possible?




650W pwr supply

You definitely need to reposition the components inside your computer. The lack of OS has no importance in this case. Detach the memory modules and the vid card and reattach them, makin sure they are inserted straight into the slots, all the way down.

For an Award bios or a brand name bios based on one.....

- if you get a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously, that usually indicates no ram is installed, or a ram problem.
Remove the AC power to the case, make sure the ram is all the way down in it's slots. On some mboards, you may need to remove the ram, install it again, in order to get it to seat properly.
If you still get the beeps, the ram you bought is probably incompatible with using it in your mboard model.

What specific brand and part numbers does the ram have ?

- a problem with the video card or it's connection in it's slot is indicated by 3 beeps, often 1 long, two short, no further beeps.

Your HD5830 card requires two extra connectors from the power supply to be connected to the card. Did you connect those ?

Under System Requirements
500 Watt Power Supply is required (minimum).
2 X 75Watt 6-pin PCI Express power connector is required.
Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products.

There is only one beep and it lasts from bootup to when i cut the power.
I connected a 6 pin connector from the power supply to the vid card. I believe there is also an 8 pin port that i left unconnected on the vid card. I could not find a cord from the power supply that would fit the 8 pin port.

Is the 8 pin unimportant or do i need to find an adapter to connect it to the power supply

You MUST connect a wiring connector from the PS to BOTH connector sockets on the card.

Do that ONLY when the AC is disconnected to the PS.

Apparently, the 8 pin connector socket can probably be used with either a 6 pin or an 8 pin connector from the PS.
The 8 pin socket probably merely allows you to use either a 6 pin or 8 pin PCI-E connector from the PS.

"I have just bought ASUS EAH5830 graphic card. There are two power connectors - one 6-pin and one 8-pin. Actually the latter is divided into 6-pin (marked as CON2) and 2-pin (marked as CON3). The problem is my PSU does not have 8-pin PCI-Express plug. Can I just connect 2 6-pin plugs? If not what should I do? Do I need an adapter 6 to 8 pin? I would prefer not to exchange my PSU...

That shouldn't be a problem, they wouldn't of given you the option of another 6 pin if it wouldn't work with your existing gear."


"The only difference between a 6 pin and an 8 pin PCI-E connector is that the 8 pin connector has two additional grounds. "

Some PSs have one or more PCI-E 6 + 2 pin pairs of connectors - a 6 pin connector that has a 2 pin connector beside it in the same bundle of wires. You can use use both connectors in the 8 pin socket, or just the 6 pin connector.

The shapes of the plastic in the socket and the plastic on the connectors from the PS are designed such that the connectors from the PS can only be installed in the correct socket in the correct place.

If your PS has only one PCI-E 6 pin connector, you can buy yourself a PCI-E 6 pin to 2 Molex wiring adapter, like this:

You can often buy that locally, at a place that has lots of parts for computers.

I will do that asap.
Hopefully that is what is causing the beeping and not some other problem.
thx for the help
