fixed: ECC supported but disabled (Skylake IMC)

Recommended Posts

Hi guys, I put together a system with ECC memory but AIDA64 is showing ECC as supported but disabled.


CPU: Xeon E3-1275V5

Motherboard: ASRock E3V5 WS (latest BIOS: 1.40)

Memory: Crucial CT2K16G4WFD824A 2x16GB DDR4-2400 ECC UDIMM


I have a CPU that supports ECC, ECC memory and a motherboard with a chipset that claims ECC support but doesn't mention ECC anywhere in the BIOS. So, is AIDA64 wrong and is ECC actually turned on? Or did ASrock screw up in the BIOS somewhere? Any other ways to check if ECC is enabled? I disabled the BIOS startup screen to watch it bootup but that didn't give any info on the memory detected. I attached the hardware report from AIDA64 if you guys want to take a look.

Thank you for the report. It seems the Skylake IMC ECC state detection method that AIDA64 currently uses isn't the proper one. We'll try to find a new method and get back to you soon in this topic.

      Can someone please help me. I've just installed AIDA64 on my Asrock DeskMini 110 (motherboard H110M-STX) and some of the voltages are missing. Is it possible to fix this. Appreciate it..

      Hello! With the Asrock Taichi X299 XE, all fans are showing up in AIDA64 except only the CPU optional fan Speed! I'm already using the latest Beta of AIDA64! In Asrock A-Tuning utility all fans are showing up! It would be great, if you can make the CPU optional fan showing up also in AIDA64! ;-) Many thanks!

      In Aida64 +5V standby voltage is reported as +5.261. Tolerance is:
      +5Vsb tolerance
      ±5% - from +4.75V to +5.25V
      Should I be worried?

      Aida 64(Engineer, v.5.92.4350 Beta),does not show properly cpu core voltage,on ASRock X370 Gaming X motherboard.
      Please fix it,in the next version.
      Thank You!

      I have skylake c236 motherboard + xeon processor + ECC UDIMM memory
      I run "best practices analyzer" scan on hyper-v role on windows server 2012r2
      And got error
      Title:Use RAM that provides error correction
      Severity Error
      Problem: The RAM in use on this computer is not error-correcting (ECC) RAM.
      Impact:Microsoft does not support  on computers without error-correcting RAM.
      Then I tryed AIDA latest beta (from this topic https://forums.aida64.com/topic/3404-fixed-ecc-supported-but-disabled-skylake-imc/)
