Dell 490 BIOS & Win 7 Pro not seeing 2nd Xeon. SiSoft shows it.

I have the exact same problem others have posted here with no solutions listed...

Issue:
Upgraded to Win7 Pro x64 from Home Premium x64 (Anytime Upgrade online), specifically to add second physical processor...

Used MSCONFIG and EasyBCD 2.2 to "force" Windows to look for more cores... nada!

Mobo BIOS will not "see" second processor, at all. Only recognizes one in either socket.

Dell docs and forums insist it is dual-socket supported in "Pro" and "Ultimate" versions of Windows.

Replaced mobo and running latest Dell BIOS (A08) to no avail...

Two tubes of thermal paste and two mobo's later and I'm outta patience.

Suggestions??

Indianatone said:

See the other post. If the bios does not see the 2nd CPU then neither will Windows. Do you have RAM installed for the 2nd CPU???

Thanks Indianatone.

Please clarify "...RAM installed for the second CPU?"

I have 16GB installed. 2x4GB and 4X2GB in matched sets across 6 sockets...
BIOS and task manager sees it all...

Nowhere have I seen anything about installing RAM specifically for a CPU.
Happy to learn.

Cheers!

I see how this could cause issues with these older mobos and chipsets.
However, a conundrum still exists b/c my other 490 has 4GB - 2x2GB sticks in sockets 1 + 2, not 5 or 8, and booted both processors on the first install.
That machine is not my prime choice, as the one I'm troubleshooting is outfitted with ultra quiet fans and sound deadening fabric for use in my studio.
Mine barely makes a sound and cores are at 35-40C when full tilt.
The other one is at an office workstation.

I am going to pull the RAM and install one pair at a time in the opposite channels sockets for "giggles", as you say.

thanks so much for your input...
I've been waking up in sweats trying to solve this!

For grins, I removed all but one stick of RAM in DIMM-0/channel-0... still one processor.
Added one more stick in DIMM-0/channel-1... nada.

FYE, here are SiSoft's findings on BOTH processors installed on the mobo:
