PE2850 won't accept CPU Upgrade to Dual Core Xeon SL9HA 3400MP 7140M 3.4GHz 800MHz
I wanted to upgrade my 2xSingle-core Xeon 3.6GHz PE2850 to a 2xDual-Core Xeon 3.4GHz CPU. Didn't work. The specs say dual core CPUs are supported. Both are the same socket layout. Is there something about the Intel SL9HA Dual-Core Xeon 3400MP 7140M 3.40GHz 800MHz FSB that is incompatible with the PE2850 motherboard? Is there a setting somewhere I need to set?

I've never seen a Dual-Core for or in a PE 2850, but keep this in mind from the manual online:
http://support.dell.com/support/edocs/systems/pe2850/multlang/processor/F6587A01MR.pdf
NOTICE:
If the front of your system chassis is labeled with a "II," your system is upgradeable to the Dual-Core
Intel ® Xeon® 2.8 GHz Processor with 4 MB L2 cache. See www.dell.com and support.dell.com
for information on processor availability and upgrade options for your system.
NOTICE:
Before you add or replace a processor, check the latest system BIOS information on the Dell Supportwebsite at support.dell.com , and upgrade the BIOS if necessary.
So, my questions naturally are:
Do you have the 2nd generation of the 2850?
Did you upgrade your BIOS before installing it?

My three 2850 are all first gen. Not a 2850 II among them. That would explain it. Good, at least now I don't feel I'm going totally crazy.
So, with a 2850 II, were I to acquire one, do you think I could plug the CPU I got into it and have dual 3.4GHz Xeon and 16m L3 cache?

According to that, you should. Of all the 2850's I have, I do not have a 2850 II either. There must not have been very many of them, because I was always under the impression that the 2850 (and all 8th generation Dell servers) would not take a Dual-Core.
Good luck.

The 3400MP processor is not supported in the 2850. The MP processors are only designed to work in multiprocessor boards with at least 4 processors(6850). I believe the highest you could go in the Gen 2 2850 is the 2.8 dual core processor. You would need to replace your mainboard with PN XC320 or NJ022. The stepcode of the processor is SL8MA or dell PN TD428.

Two of mine I checked are running 2.8 and 3.2, both with XC320 motherboards.

The XC320 will take up to 3.6 single core but only up to 2.8 dual core.
