Well I have dell precision T3610 with Intel Xeon E5-2660 and that is currently enough for me. But in future if I want to upgrade it I think the best one I could get is Xeon E5-2697 v2 as all v2 Xeons are supported. I have also asked the vendor I bought this PC from and he said it can have max 12 core processor not 8. May I ask that are you using it as a server or a desktop?

I have the same Dell model. Is it possible to upgrade to a higher CPU version v3 or v4. I don't see any on the list link you posted. For example, the Xeon E5-2687W v4 has better specs and uses the same socket (FCLGA2011-3). Could I upgrade to that one rather than the 12-core v2 you said could work (Xeon E5-2697 v2)

Also.. is there a difference between the FCLGA2011 and the FCLGA2011-3 socket?

No, it's not possible

The cases are these, doesn't matter the brand

MB allows v1 , then a newer revision of the MB allows v1 and v2
MB allows v3 , then a newer revision of the MB allows v3 and v4

In some cases you may get directly a MB allowing v1/v2 ( or v3 and v4 )

And that's all. The same happens now with the newer xeons.

Initial revision allows Gen1 , subsequent revision allows Gen1 and Gen2

FCLGA2011 is 3rd/4th gen intel core ( xeon e5 v1/v2 )

FCLGA2011-3 is 5th/6th gen intel core ( xeon e5 v3/v4 )

I am considering an upgrade for my T3610, and please excuse me I couldn't be clear on the matter about "the newer Revision of MBs" 

My system has E5 1620 V2 CPU. What is the highest possible CPU upgrade for this motherboard.

Is E5 2697 V2 Ok for instance? I think there are a few more higher level V2 CPU's, too. (2698 and 2699)

Thanks in advance

Supports Single Processor
Intel® Xeon® E5-1603 (Quad 2.8GHz Turbo, 10MB)
Intel® Xeon® E5-1607 v2  (Quad 3.0GHz, 10MB
Intel® Xeon® E5-1620 v2 (Quad HT, 3.7 GHz Turbo, 10 MB)
Intel® Xeon® E5-1650 v2 (Six Core HT, 3.5 GHz Turbo, 12 MB)

Recently upgraded my T3610 to E5-2697V2 12 Core CPU, I used this system for video editing and rendering. 

Now recently this E5-2697V2 CPU drop price a lot. May be most of this kind system are old and not supported by the coming Windows 11. No TPM version 2.0. 

If your current system is installed with 16GB or below, please consider to upgrade the system RAM to 32 GB. This will help to improve the system perform.  I have upgraded my system RAM from 16GB to 64GB. 64GB is a bit over kill, non of the application use up to 13GB of RAM. If you current system already installed with 16GB get another 16GB ( 4GB x4, this is cheap), total 32 GB will be enough.  

Have you used a standard heat sink? There was no problem with overheating of the processor?

And does it make sense to replace the E5-1650 V2 with this processor? The system is to be used for rendering in Davinci Resolve and Cyberlink?

I have 64 GB RAM 1866 Mhz ECC and GTX 1070 Ti installed.

Hi, I have upgraded T3610 with Xeon E5-2697 v2 CPU. In my opinion this is the fastest CPU you can use in FCLGA2011 socket. 

Works fine, great performance boost

My upgraded T3610 with Xeon E5-2697 v2 64GB RAM, 1000GB SSD system was running fine until recently the power supply broken down. Now I am planning to upgrade the power supply unit to 1300W type. This power supply unit is on the way delivery to me.

I am using this system mainly to run the Power Director software for video editing, during rendering all the casing and CPU fan are running at it maximun speed. I think the original Dell CPU cooler is not good enough to handle the heat generated from the 130W CPU. 

I would like to ask, any better air cooling fan can fit into this T1300 Matherboard layout and the casing ?  If you have any suggestion please let me know.
