I think it depends on the revision of the motherboard installed in the 5810. Initial revision is only v3 , later revision is v3 - v4.

You could look at the part number ( with hwinfo, by example ) of the motherboard, post here, and see if someone has info

Thanks mazzinia! Would this screenshot from CPU-Z tell what you need?Looks like might have been wrong on the chipset, for the 5810 from my initial post, but C612 hopefully isn't too far off from C610 compatibility wise. Thanks!

I can try to research ( once the site shows the image )

Great, thanks for finding that for me! That's good to know this version of processor will work with my system.

Yw, good luck with the swap. 14 cores are really not bad at all, and it's also 20Watts less.

Keep in mind that the base frequency is 2.40Ghz vs your current 3.00Ghz... so your mileage may vary depending on the task

Thanks! I'm trying to figure out if i should bother at all. I ran a Geekbench on my current processor, and the single core result was a couple hundred points higher than the other. But the multi-core test was much higher in comparison, as was to be expected. I go back and forth on it

Now if only this CPU would fit into a Poweredge T420, then this would be an easy decision. But oh well

Yep, not a simple choice

Unless sneaking that R730 and substituting the T420
