Data inconsistent in memory measurements Signs of unclear RAM performance Possible causes and solutions
Hi everyone, i was checking some ram readings since i was suspecting XMP wasnt doing his thing, i build my rig in 2017 with this asus prime z270f gaming, i7 7700k and 2 8gb sticks of ddr4 2400 corsair vengance ram so i got 16gb total, in 2019 i bought another kit same size but the top speed was rated at 3000 mhz, i set all memory timings and speed with XMP to match the 2400 mhz modules that where runing in dual channel (slot A1 B1 for the older modules and A2 B2 for the new ones) you can see in the attachments the first 2 captures are from the first kit installed in slot 1 and 3, the second in 2 and 4, and the second kit says single channel.... is that a bug? what´s the deal? did i mess up? i´ve been working and building computers since 2005 until 2014 so i now some technical stuff, can someone enlighten me on this issue if there is any? i updated the BIOS to the newer non beta one, it was 0801, the newer one said it was for windows 11 support and said "beta state" at the asus site, BIOS shows target memory speed at 2400 and each module at that speed in the monitor tab, but when i switch to each individual slot stats shows the second kit with 2 speeds 2133 and 3000 only while the old kit shows 2133 and 2400
It clarifies that the setting is Single Rank. This is unrelated to what you mentioned. Your RAM operates in dual channel mode, featuring two dual rank dimmers and two single rank dimmers.
The "Memory" section displays your RAM's current performance and timing details. It operates in dual-channel mode at 1200 MHz (2400 MT/s), meaning it matches the advertised speed—marketing style translates this to an effective clock speed of 2400 MHz due to double data rate in DDR technology. The SPD chart lists potential speeds your RAM modules can achieve, such as specific JEDEC and XMP standards, but doesn't reflect real-time usage. As mentioned, dual rank refers to having two ranks on a single stick for better latency, whereas dual channel allows simultaneous access to two channels, boosting bandwidth.
