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:
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.
Before you add or replace a processor, check the latest system BIOS information on the Dell Support
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.
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.
