I have a Dell PWS 690 that I bought from the Dell Outlet store in Dec 2007. It has the 0DT029 motherboard, Xeon 5110 CPU and BIOS A08. I want to upgrade to dual quad-core CPU's, 5345's.

 However, I have read that despite Dell's sales lingo of supporting quad-core CPU's, there may be some incompatibility for this MB.

So.... does anyone know for sure if this configuration can support the 5345's?

I did a chat with Dell Tech Support today and was not given a clear answer. Yet again I have been less than impressed with the level of knowledge and help available from Dell in relation to the PWS 690. Other, standard PC's they have been very helpful in most cases, but the PWS seems to befuddle them. 

Thanks.
