Hello,

according to this 

https://browser.geekbench.com/v5/cpu/12675803

that motherboard should work with v4 cpus

and there's even this 
https://browser.geekbench.com/v5/cpu/12427794
showing a 22 cores cpu

Hi!

Thanks for the reply, I appreciate the links.

The screenshot bellow is from DELL T5810 OWNER MANUAL I am not hardware expert by any mean, so I read the bellow specs as: You can add up to 14 core processors on this machine. What makes me worry is that my current processor is v3, and the one that I want to add is v4, and I have no idea will it work.

Normally there are various revisions of a mb for this kind of system. An earlier one that would work only with v3 , and one or more latter ones that would do also v4 aside v3.

Model 0HHV7N is a specific mb revision ( each has a different model tag ) and matches the one used in those 2 benchmarks. As such, means your mb can use v3 and v4, moreover it can use also that 22 cores cpu apparently.

In any case you "may" need to upgrade the bios to the latest version before changing the cpu.

Hi

Thanks for the quick reply.

You are right about this. On various manual owner for dell t5810, you can find various info. For example, I have seen owner manuals  which says that system can take max 128GB of Ram, and some say that it can take 256 GB of Ram. 

As far for the bios upgrade, that is not problem, what makes me worry is that I want to be somehow 100% sure before to order the CPU, and how to find out which cooler should I use for the new CPU.

Sounds old, are you sure?

You have this upgrade CPU or can get it cheap?

I suggest you stick to CPUs that the machine originally shipped with. Those should be in either the Owners-Manual or Brochure. But even then, since this is a Workstation-class machine, it might have shipped with two or more different motherboard revisions to accommodate various main-processors.

Personally, I would just be glad it's still working, and plan migration to the next one. OK, 2015 is not that old, but still.

@t5810 , it's depending on what type of applications you are planning to use.  Then you can determine accurately which components to upgrade.  Here are my thoughts.

Going to an E5-2690, you will lose the single core performance, as it was designed for dual processors system.  You are dropping from 3.50Ghz to 2.60Ghz.  To get optimal upgrade, you need to stay with E5-16xx processors.

If your usages can take advantage of multi-cores, do you plan to replace memory as well, because going from Haswell to Broadwell, processors can run higher clock on RAM, but you can't increase memory clock with your old RAM

For dollar/performance value, an E5-2690 v3 can be had for 80 USD and v4 almost 200 USD.  The best value will be an E5-2680 v3 for only 60 USD.  At 2.50Ghz, its core performance at 93% of the E5-2690 v3, and the TDP drops to 120w, hence running cooler.

On a positive note, you can use your old cooler for both v3 and v4 processors, no need to change cooler.

Anyone can point me how to determine that specific processor that I will chose is compatible with my motherboard. Which parameters should I look?

When I contacted Dell, I get this link: https://www.cpu-upgrade.com/CPUs/Intel/Xeon/E5-1680_v3_motherboards.html, so I can chek my self which Motheboards support the E5-1680 v3, which is not helpful itself, but the link can be used to make educated guess.

Sure enough, what I wanted  is sure answer, and it seems I am not going to get it. I over estimate the DELL support  I guess. Any help will be deeply appreciated.

I have this same computer hooked up with an i7 5960x which i recommend as it offers probably the highest single core performance out of any of the other cpus

Hi

Thanks for your reply. I sell my Dell T5810 and I get custom build machine with AMD on it.

Cheers, Z

I know this is a tad outdated, but it took me forever to find any answers on my specific question and I kept getting redirected to this page, so I'm going to give my experience here for anybody else who may land on this...

I was able to install an E5-2699 v4 CPU into the Precision 580 (0HHV7N)
