Zakkorn Posted May 5, 2015 Share Posted May 5, 2015 My PC spec is Dual Xeon E5 2690 V3 Asus Z10PE-D8 WS 8x8GB Kingston Corsair 1200Watt Gigabyte Titan X Today I install another 4 memory dims (till yesterday I only had 4x8GB RAM) These would make my system run on Quad memory channel. CPU-z correctly detects Quad Channel (till yesterday detected Dual) But in AIDA while I have better scores in the memory benchmarks (almost double score) still says Dual Channel Is this a bug or what?

Fiery Posted May 6, 2015 Share Posted May 6, 2015 Such issue could be because Haswell-EP processors feature 2 memory controllers, each with 4 memory channels (total of 8 memory channels per socket). And there're many configurations where 4 memory channels are assigned to a socket, but not by utilizing all memory channels of the 1st IMC, but 2 channels for IMC0 and 2 channels for IMC1. And on the Cache & Memory Benchmark panel AIDA64 will show the utilized memory channels count for the very first IMC it can find in the system. You can go to the Motherboard / Chipset page to see all the IMCs you've got in the system, and check the actual memory channel utilization for all of them.

Fiery Posted May 11, 2015 Share Posted May 11, 2015 Please note that we will revamp the active memory channels enumeration in the next AIDA64 beta build (due in a few days from now), to avoid showing confusing information on the Cache & Memory Benchmark panel.
