A friend bought foxconn Sis 661fx7mj motherboard and a dual core processor. now he was told that this motherboard can support a dual core processor but i looked it up and it said it supports pentium d,4,celeron,celeron d processors.

can someone elaborate on this?

but aside from that, would the cpu cause the motherboard to not post/boot? the fans spin up, but just a black screen appears.

oh and it also has a 1gb ram, 120gb hdd

i took the cmos battery out to try to clear and it still showed up with the black screen.

i also unplugged everything just to try and see if it posts.

now my only other guess would be the cpu - :-/

thanks for the help!

The board was a horrible choice.

"Supports Intel®Pentium® D/Pentium® 4 /Celeron® D processor in an LGA775
package"

A pentium D is a dual-core CPU, but the board does NOT support a Core 2 Duo. What CPU are you asking about?

Also, the board *should* have been benchtested before installing it in a case...my guess is this wasn't done? Take it out, lay it on the bench with just the CPU w/HSF, one stick of RAM & monitor connected to the onboard video. Connect the PSU (20-pin & 4-pin ATX plugs) & jump-start by momentarily shorting the 2 pins on the board that go to the case switch with a screwdriver. It *should* post.

The Pentium D is a dual core CPU!

Who told your friend that that motherboard supports dual core processors, because the specs say that it doesn't ? If it was the person who sold it, I would return it and get a motherboard that does support dual core processors. There are plenty of those types of motherboards at a reasonable price.
Also, what type of RAM are you using ? That motherboard only supports DDR.

he bought it at compusa - geniuses i know.
he is using ddr ram.
he bought a "pentium dual core processor LGA775pkg 1.6ghz, 1mb l2 cache, 800mhz fsb"

i agree with you jam, the board is terrible.

Yes, the Pentium D is a dual core CPU. I meant to say that if you were told that it supports core 2 duo processors, then I would return it.

Unless I'm mistaken, there is no Pentium D that runs at 1.6GHz. I believe what your friend probably bought is an E2140 Allendale which is not supported by that board.

yes jam you are correct.
thank you all for your input

I can see how people can get confused with thinking that a Pentuim D and a Pentuim Dual Core are both the same thing in terms of support for older intel motherboards that only support Pentuim D's, but it's not. Intel should have made it more clear.
