We were finally able to try to install the two Xeon X5460 into the Precision 490 Workstation.
They did NOT fit.
I know Precision 490 use 5000x chip set. I checked other brand name motherboard with 5000v chip set. And find they can support 54XX sequence CPU. So it is not hardware issue. I hope DELL will release a new BIOS upgrade to support the new quad core. Or if someone can find what's the motherboard maker and download bios update from the factory.
Let's keep working.
I know this is an old thread but does anyone have anymore information on this?
Was someone able to take a factory dual dual core model and throw quads into it?
