Does the DDR Interface/Memory Controller of Tiger Lake UP3 i7-1186GRE Support ECC?

lo3 — Mon, 06 Jan 2025 03:09:17 GMT

Hello,

I am conducting some research on the Intel Tiger Lake UP3 i7-1186GRE processor, specifically regarding its memory controller. I would like to know if the DDR interface/memory controller of this processor supports ECC (Error-Correcting Code) memory.

I haven’t been able to find any clear references to this in Intel's documentation or related technical materials. To avoid using incompatible memory, I would like to confirm whether this processor supports ECC memory. Additionally, if possible, I would appreciate any details on whether there are specific hardware or software requirements to enable ECC functionality.

Thank you for your help! Looking forward to your response!

Dear CarlosAM_INTEL,

Thank you for your response.

I have reviewed the information on the website you provided and noted that the 1185GRE supports memory ECC. However, in document #575683 (as shown in the image below), it appears that ECC support is only available for the H-series. Could you kindly confirm again whether the UP3(i7-1186GRE) supports memory ECC?

Additionally, could you clarify what "N/A" means in the context of the LPDDR4x listed in the image below?

Looking forward to your confirmation.
