ECC-RAM on non-ECC motherboard

[rman1]

Hi Intel,

I would like to ask, whether will an ECC memory module work perfectly on a non-ECC motherboard (w/o the ECC functionality, of course).

Example of application:

Motherboard

https://www-ssl.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-board-dh87rl.h... Intel® Desktop Board DH87RL

RAM

http://www.crucial.com/store/partspecs.aspx?IMODULE=CT25672BD160B CT25672BD160B - 2GB, 240-pin DIMM , DDR3 PC3-12800 from Crucial.com

The reason of the choice is, that I want to use DDR3L (1.35 V) in the favour of minimizing the amount of emited heat, but cannot find any such non-ECC modules.

Thanks for your answers in advance!

Hello Rastaman, the DH87RL motherboard supports non-ECC memory only. http://www.intel.com/support/motherboards/desktop/db-dh87rl/sb/CS-034215.htm Intel� Desktop Board DH87RL — System memory

A Haswell processor may support ECC memory 1.35V, but the processor could demand a 1.5V from the memory and this could generate damage on it.

Only Xeon processors support ECC memory for sure, but if the motherboard does not support it, I won't recommend you to use it.

If you use an ECC memory on the board, you may get a memory error (3 beeps), therefore the system is not going to post. In the other hand, it may work, but eventually you may start getting errors.

My recommendation will be to use memory under specification, which are non-ECC DDR3-1600/1333 1.5V.

Hi Sylvia,

thanks a lot for your expertised answer! Do you know of any non-ECC 1600 MHz 2 GB DDR3L modules, please (if possible, available in Europe)?

Thanks a lot again!

Kind regards

Hi again, Sylvia,

sorry for bothering you again, but I would like to ask, how is it with the other required parameters of a memory used.

E.g. the board specifications say:

DIMM capacity Configuration SDRAM Density SDRAM Organization Front side/Back side Number of SDRAM devices2 GBDouble-sided1 Gbit128 M x 8/128 M x 816

http://www.intel.com/support/motherboards/desktop/db-dh87rl/sb/CS-034215.htm Intel� Desktop Board DH87RL — System memory

I found a module, which has 8 devices.

http://www.micron.com/products/dram-modules/udimm# fullPart&192=0&220=3&223=1&225=5&235=2 UDIMM - Micron Technology, Inc.

Whould that cause any compatibility or other troubles?

Thanks again!

Best

Would you please provide me the complete model number of the memory you found? The link you attached me is giving me general information.

Number of SDRAM devices (16) is because this specific memory is double-sided, that means that each stick have to contain a chip distribution in the two stick sides and each chip has to be made based on 1Gbit density for a total of 8

For more details about memory construction and specifications on the memory please contact the memory manufacturer and they can give more information about that.

Hi Sylvia,

it's in the "Part Number" column: http://www.micron.com/parts/modules/ddr3-sdram/mt8ktf25664az-1g6?pc=%7B2537FA94-C828-4DE7-99C4-6D90B... MT8KTF25664AZ-1G6

Thanks!

It is hard to say if this memory is or not going to work on your board since it is not on our tested list.

You can give it a try using only one stick first and then adding another one in order to check the behavior of the board.

These are the Micron memorys tested
