fixed: SPD display (DDR4 XMP 2.0)

[Grestorn]

I've got problems matching the RAM SPD information displayed by AIDA64 with the one shown by CPU-Z or the BIOS. 

 

Here's what AIDA shows:

Memory Type DDR4 SDRAM
Memory Speed DDR4-2133 (1066 MHz)
Module Width 64 bit
Module Voltage 1.2 V
Error Detection Method None
DRAM Stepping 00h
SDRAM Die Count 1

And this is CPU-Z output, the BIOS shows the same values: 

 

 

 

Especially the timings for XMP 2800 and 3000 seem to be different in AIDA... Am I reading the values wrong somehow?

I've just sent your a private message about this issue.

The issue is related to decoding DDR4 XMP 2.0 memory profiles. It will be fixed in the next AIDA64 update due in 3 days from now.

We've just rolled out AIDA64 v5.00 stable release, that -- among many other improvements -- includes the mentioned bug fix about DDR4 XMP 2.0 profiles decoding:
