Memory upgrade: ECC or Non-ECC (RAM)

I'm looking at upgrading the RAM with 8GB RAM, I used Crucial.co.uk and ran a system scan which determines your computer model and compatible RAM upgrades, however it advises that you shouldn't mix ECC RAM with NON-ECC. I have been advised to contact lenovo to find out what RAM this model would have been shipped with. 

 

Please see below advised RAM upgrade - there is also a ECC version which is recommended for this computer;

 
8GB DDR3 PC3-12800 Unbuffered NON-ECC 1.5V 1024Meg x 64 part #:CT5205806
  • DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.5V • 1024Meg x 64 •
  • upgrade for Lenovo ThinkCentre E73 Tower system.

 

Computer specification:

 

S/N - xxxxxxxx

Model no. 002PUK

Product ID - 10AS002PUK

Machine type - 10AS

 

We are looking at upgrading a potential 4 more machines, please could you specify what information you would need from us about each machine in order to tell us the RAM spec

 

Many thanks,

Rebecca

Re: RAM upgrade ECC or NON-ECC

Lenovo E73 will only take non-ECC memory. Originally there is 1 module 4GB DDR PC3-12800 installed (provided it was not upgraded afterwards). Source: Link

So CT5205806 is fine.

 

I find it strange that Crucial would suggest ECC memory for this one. Actually - if you select E73 manually, only choice is non-ECC memory ... Link

Re: RAM upgrade ECC or NON-ECC

I have Corsair Vengence Pro 16GB in mine

 

 

Along with a Gigabyte GeForce GTX 970 running surround displays, I can't seem to bog it down! Literally, I never have to close anything, it just keeps going. There's no ceiling, it's amazing.

Re: RAM upgrade ECC or NON-ECC

I tested my E73 with ECC ram from a HP¨workstation. The E73 functions normal with ecc ram although the i5 cpu doesn't support ecc ram according to Intel's website

I tested my E73 with ecc ram from my HP workstation. It worked fine although the i5 doesn't support ecc ram according to Intel's website.

Anybody with an explanation?

Re: RAM upgrade ECC or NON-ECC

Are you sure that the HP had ECC memory installed?

 

Can you check via these methods, let us know the results:

Re: RAM upgrade ECC or NON-ECC

So I did the test with the HP Z210: it is ECC memory.

 

I also see there is a difference between registered and non-registered memory, does somebody knows the difference? How can you know which one you have installed? Or is that not important for the system

Re: RAM upgrade ECC or NON-ECC

As written above, and at this thread here.   The chipset specs, published by Intel, state that the Intel H81 Chipset used by the E73 (and M73) does not support ECC memory.   (Perhaps it worked for your test, but it's not designed to work that way, and you could get erratic operation.)

(The C226 is a workstation and server chipset -- used in ThinkServer TS140 with ECC memory.   Additionally, you would need to have an Intel processor that supports ECC memory, many consumer-focused models used in a lower-end desktop like the E73 do not)
