IMC Fail with IPDT on NUC7CJYH with later BIOS versions

Since I updated the BIOS from 0047 to 0051, the Intel Processor Diagnostic Tool displays an "IMC Fail / Unable to retrieve memory size" error. The issue does not occur with BIOS version 0047 and earlier, but the only versions available to download are 0050 and 0051, both of which exhibit this problem.

 

I have tried several different memory modules from the compatibility list, all of which pass a memtest86 test. I have also tried another identical NUC unit which exhibits the same symptoms.

 

Easy steps to reproduce:

Update to BIOS version 0050 or 0051.

Reset BIOS settings to default.

Insert one or two 4GB memory modules.

Run IPDT 4.1.2.34 on a clean Windows 1903 install.

IMC error shows.

Hello CharlesBrown,

 

Thank you for posting on our Intel Community.

 

 

In order to have more details about this issue, please provide the following details:

 

 

  1. Click the menu where it says summary to change to Detailed View. 
  2. To save your scan, click Next and click Save. You can save the file to any accessible location on your computer. 
  3. Please attach the document to the next post. 

 

  1. After running the test, please go to the "file" tab. 
  2. Click on "View results file". 
  3. Save it as a text document and attach it to the next post. 

 

 

I would also recommend you to perform a BIOS recovery by the security jumper, please follow these instructions:

 

  1. Download the Recovery BIOS (.BIO) file.https://downloadcenter.intel.com/download/28892/BIOS-Update-JYGLKCPX-86A-?product=126135
  2. Copy the recovery file (*.BIO) to a USB device.
  3. Shut down the computer and unplug the AC power adapter. 
  4. Please remove your drive. 
  5. Open the chassis and look for the BIOS security jumper, it is yellow and is close to the RAM slots. 
  6. Please remember the position that it has, should be on the 1-2 pin. 
  7. Plug the USB device into a USB port of the target computer and turn it on.
  8. Wait 2–5 minutes for the recovery process to complete.
  9. The computer turns off when the recovery process is complete, or it prompts you to turn it off.

 

 

Best Regards,

Hi,

Thanks for your reply.

I have attached the files as requested and I have censored the serial numbers as appropriate.

I have performed a BIOS recovery as advised but it doesn't solve the issue.

As mentioned earlier, you can easily reproduce this issue by following the steps I outlined.

Regards

Hello CharlesBrown,

 

Thank you for waiting for our response.

 

We performed the lab to try replicating the issue with no success, using the same environment and the BIOS version 0051. We did not get any error while running the Intel® Processor Diagnostic Tool. So based on this information, we would recommend you to get in contact with Intel Customer Support to check the warranty status and options on the unit(s).

 

Best Regards,
