memory remained stable despite enabling the XMP profile.
My specifications include an Asus H170 Pro Gaming, Intel Core i5 6500, Corsair vengeance 1x8GB 2400 MHz RAM, GTX 960 4GB, and a Corsair CS 550m. I noticed the RAM was set to 2133 MHz instead of the intended 2400 MHz. After checking the BIOS, I found an XMP profile supporting both 2666 MHz and 2400 MHz. I activated the 2400 MHz setting and restarted the system. However, when I booted back in, the RAM frequency remained at 2133 MHz.

The specifications page mentions that due to Intel chipset constraints, DDR4 modules in XMP mode will operate at the maximum transfer rate of 2133 MHz. It asks why the manufacturer offers a 2400 MHz XMP profile in BIOS, suggesting it might be about timing or latency adjustments. The user also notes their H170 Pro gaming motherboard and provides the link.

* Because of the Intel® chipset, DDR4 2133 MHz and above memory modules in XMP mode will operate at the highest transfer speed of DDR4 2133 Mhz. What is the purpose behind the motherboard manufacturer offering a 2400 Mhz XMP profile in BIOS? Is it about reducing timings or latencies? Also, my H170 Pro Gaming model uses this chipset and I see the same problem here. The link to the motherboard is https://www.asus.com/in/Motherboards/H170-PRO-GAMING/
The information provided discusses the limitations of DDR4 memory speeds and the role of XMP profiles in motherboard BIOS settings. It compares the H170 Pro gaming model with other configurations and seeks clarification on why a 2400 MHz XMP profile is recommended despite only supporting 2133 MHz.
Check the memory section of the free tool CPU-Z, and if it displays 1200 for frequency, you're likely seeing 2400.
The XMP profile is located on the RAM stick, not the chipset. Your CPU and your Mobo are compatible with DDR4 2133, but the RAM you purchased can work in another system that supports 2400.
Check the memory details in CPU-Z; if it lists 1200 MHz, the actual frequency is 2400. Your RAM is only at 1064 MHz—why does Asus include an XMP profile that doesn’t match your chipset? Also, would adding another 2133 MHz RAM impact dual-channel performance?
I answered your XMP question before. However, Asus does not offer the XMP profile. It's on the RAM stick and made by Corsair. Additionally, because you only have one RAM stick, you're operating in single channel mode. If you wish to use dual channel, obtain another RAM stick that matches the one you currently have. Mixing speeds or brands is not advised.
