Both E5-16XX v3 and E5-26XX v3 family works for T5810. And in most cases, 16XX for single CPU system and 26XX for dual. If 8 cores is good enough, E5-1680 v3 may fit your needs.
However, memory speeds supported by the varies processor are different. For example, if your system installed with 2133 MHz memory and an E5-1680 v3 CPU, memory would only runs at 1866 MHz. Only E5-2637 v3 or above support 2133 MHz memory running in full speed. Therefore, check those in your system before choosing new CPU.
V3 stand for Haswell-based Xeon CPUs. Higher version like V4 (Broadwell-based) and V5 (Skylake-based) would not work on your system while they are in totally different bridge micro-architecture and socket.
For choosing between 16XX and 26XX, check on Wiki. Take 1680 and 2667 into comparison. They come with same value of cores, frequency, cache level and supported memories. The only difference is on I/O bus which distinguish them from uni-processor and dual-processor. And you can see that a 2667 cost US$300 more than a 1680. Therefore most people choose 1680 for a single CPU system in normal cases, unless you have concerns on memory speed as mentioned on my previous reply.
Hey Paul, I install the Intel Xeon E5-1680 v3 CPU in Dell Precision t5810.
It is working great. Up great your BIOS first. If you have slow (PC4 - 17000) memory in your Dell it will run with the speed of the memory. If you have a fast (PC4 - 21300) memory in your Dell and you want to utilize a full benefit of that memory, you need a Intel Xeon E5-26xx v3 series CPU. The Intel Xeon E5-2637 v3 CPU is the lowest performer of the series. Here are the options that I personally installed:
Intel Xeon E5-2650 v3 S-stepping: SR1YA
Intel Xeon E5-2680 v3 S-stepping: SR1XP
Intel Xeon E5-2690 v3 S-stepping: SR1XN
and the fastest that I Install in the t5810 is Intel Xeon E5-2697 v3 S-stepping: SR1XF
Performance was calculated with fast memory, do not mix fast and slow memory modules, because your Dell will run on the speed of the slowest memory module. Speed is determent by the speed of a FSB of the processor.
P.S. There is v4 CPUs that will work with this workstation, but I cannot guaranty if they will work with your motherboard, I recommend to stick with knowing working CPUs.
V3 stand for Haswell-based Xeon CPUs. Higher version like V4 (Broadwell-based) and V5 (Skylake-based) would not work on your system while they are in totally different bridge micro-architecture and socket.
The listing has to be a mistake then, right? Which would also explain the price? It's probably actually a v3?
I'm fine if it is, it's still a starting point at least and it looks like a 12-core, lower TDP upgrade will be dirt cheap - but I don't want to order that yet until I can confirm this thing can't _actually_ take a v4 CPU as the listing implies.
Further checked on the official T5810 SpecSheet and found no V4 CPU listed. However, Userbenchmark do shows builds installed with V4 CPU like E5-16450 v4. Therefore, those you planned to order should be V4 CPU and listed correctly.
When compare with those V3 listing, the V4 one even with double-sized memory and SSD but interestingly in half price. Not a bad deal!
@Hyacin , I hope that you didn't forget to apply additional 25% off. It brings the price down to 456 CAD or 357 USD. Very good find for a Win 10 pro system with Xeon quad, 32 GB RAM, Quadro 4GB Maxwell card and 1TB storage.
Yeah that's why I was so confused! But you're right, and I went and checked the multitude of (difficult to query/explore) options listed on UBM and ended up ordering a pair of E5-1650v4s for them!! Super excited!
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.
FWIW, I have a 5810 with a HHV7N motherboard that originally came with a E5-1603v3 and just installed a E5-2690v4. I ran the Dell Command | Update tool and made sure everything was up to date (it ran a BIOS and firmware update). Other than that, it was plug and play.
And yes, it's a massive difference in performance.

Thanks BCB!
So V3 to V3 is a must?
Also, can you, does it make sense to go from 16xx to 26xx?
My motherboard is a single processor.
Thank you so much for the reply.

Thanks again Cowboy.
I am having a hard time locating these, any recommend searches?
So I have narrowed it down to...
E5-1660v3
E5-1680v3
E5-1681v3
E5-1686v3
E5-1691v4
I have checked the Bay and jiji, and there are not many options.
There is also a huge price difference between 1660 and 1680.

Hi, sorry, MAJOR thread necro, but this is completely on point for my question -
I just ordered a couple of these ... https://www.dellrefurbished.ca/item/dell-precision-5810-tower-5f85dd8a/dell-precision-5810-tower/1.html?child=dell-precision-5810-tower-000019&p=1
The listing has to be a mistake then, right? Which would also explain the price? It's probably actually a v3?

You can throw an E5-2680 v4 in there.

The extra 25% off is what sold me!
