Instruction: Answer the given question using the supporting document.

Input:
Question: It supports ECC but is it REQUIRED?  I.e., can non-ECC unbuffered memory be used?
Document: (I am not sure that Non-ECC, Buffered is even available. )- According to Lenovo Tech Support, Kingston RAM is not supported. They stated that Kingston RAM is NOT recommended in the TS140.
I set up this box with the following in a couple hours:- 12GB (3X4GB modules) pc3-12800 ddr3-1600 ECC UDIMM's- Blu-Ray/DVD/CD Reader/Writer O.D. replacing the Half Height O.D.- ICY Dock Duoswap 2.5&#34;/3.5&#34; dual drive bays in 2nd.
like SYBA.If you are planning on adding RAM, take into account the following parameters:- ECC is OK.  Buffering/Registered is NOT. ECC, Buffered/Registered RAM will NOT work in these servers. I tried a couple brands and they would not even post the BIOS. Lenovo sends Hynix or Samsung ECC UDIMM's with the machines.- The TS140's BIOS is NOT adjustable for RAM frequency or CL. If you install RAM that is outside std.
I used the Lenovo CD to update the drivers, and after doing a couple of license reactivations, I was fully operational in about an hour.Over the last few days I've been amazed at just how quiet this server is - about as quiet as the MicroServer. I think it will draw some more power vs the previous server, but hopefully not so much that it will be painful when I get the electric bill.
I love this computer. I added memory, a hard drive and a solid state drive. It is super quiet and fast. It is a shame that the average person can't buy good computers pre-loaded with a great operating system. If more people tried it, they would never buy Windows or pay the extremely high premium for Apple MAC OS.
Again took me a while. It turned out to be under "Advanced" > "CPU setup".2. Possible optical drive problem:  Another issue I encountered is quite odd. When I used the optical drive to install the operating system, the install failed with an error message saying that files are corrupted. But I knew that was not the case, because the same disc was used to successfully install the same operating system on other machines.
from them. Bigger P.S. are available many places so that shouldn't be difficult to change out if you desire.As an FYI - The M.B. slots are PCIe 2.0. I had difficulty in using cards I previously used in these TS140 boxes. None of the PCIe 1.0 cards worked in these boxes even though PCIe 2.0 is supposed to be backward compatible with PCIe 1.0.
Should I be afraid to install my own hard drive and OS? Should I go with a I3 or a E3? How upgradeable? Is it so small I can't add hardware? What I love about this computer is that it appears I could upgrade all the way to an E7 or I7 with this CPU socket, and up to 36 gigs of memory (remember behemoth 20 gig hard-drives?). There is a good amount of space in the equipment bay for more hard drives and PCI cards.
(Initially I tried out with Raid5 configuration but the Raid driver performance was disappointing with constant high access rate on the hdds.) The Xeon server is used on production as a domain controller setup with DNS & WSUS roles as well as a DVR recording video streams from 10 IP cameras 24X7 over the home office LAN. Remote login is installed so it allows me to see the real time surveillance monitor display when I am away from home.
This is a fantastic bargain, picked up for a song and dance (well below the $399)!Very pleased, out of the box I noticed some differences over the i3_4130 option:1. half height dvd drive instead of 5 1/4"2. additional fans in the 5 1/4" expansion slotsI doubled the memory (took the matching 4GB ecc DDR3 1600Mhz ram I pulled from the i3 version I bought previously), and added a 2.5" seagate hybrid drive.
Answer: yes, non-ECC unbuffered memory can be used in this, but it comes with one stick of ECC so to support dual channel it would need another stick of ECC
