Need Help Upgrading Xeon E5-1603 to ?? Dell T5810

Hello All,

Can anyone point me in the right direction? I have a Dell T5810 Workstation. I am running VM, and it is bogging down on CPU (all 4 at 100%) Windows 7 when I am programming.

I had read that the T5810 supports up to 14 cores, 8 would be great!

This is my current setup...

The extra 25% off is what sold me! 

I've ordered a couple E5-1650v4s for them - the single core performance even slightly exceeds the Ryzen 5 4600Us I have my heaviest Proxmox workloads running on - and I figured single core is where I'd feel it the most if it were sluggish ... plus with only 32GB (and upgrade options on that front appearing to be very expensive) I don't imagine running more than 4-5 VMs on each at MOST, so 6c/12t should be perfect!

My first Xeons since an ill-conceived 2U PowerEdge 2xxx purchase I made in like 2002 (who knew they sounded like jet engines and wouldn't be good in an apartment?!)!!  Super excited, can't wait for them to get here!


You have confirmed that the E5-2680v4 works in the T5810? If so that seems like a plausible route for my potential upgrade path. From E5-1603v3 to E5-2680v4 should be a heck of a difference.

There was a bios upgrade that permitted v4 processors to be used in place of v3s (somewhere around A14.)  Look it up to be sure.  There were at least two different motherboards used in T5810s (OK240Y was in the ~2015 machines, OHHV7N was used around 2016 and afterward.)  I've seen most v4 processors listed in UserBenchmark builds for both motherboards.  It's easy to search their builds - just enter a processor you are interested in, i.e. "Precision 5810 e5-2687w v4" and any builds will pop up and you can see the mobo and other details.  If you upgrade to the latest A34 bios first, you'll likely be ok with any of the E5-16xx or E5-26xx v4 processors.  While I haven't personally verified this, I'm looking at doing the same.
