BIOS maximum dram frequency setting is 1600mhz
Hello, I recently purchased a brand new 2x4GB Ripjaws DDR3 1866MHz motherboard. However, when I accessed the BIOS settings, the maximum DRAM frequency listed was 1600 MHz, while my motherboard claims it supports up to 2400 MHz. Here is the link to the image: https://imgur.com/a/k90GR8d. My motherboard model is ZH77A-G43 and the CPU is an i7-3770.
As previously discussed, it's likely you require a K cpu to effectively utilize increased RAM rates. When compared to the 8th generation Intel CPUs, DDR4 standard speed is 2133MHz; the I5-8400 can operate at 2666MHz, but a K cpu is necessary to achieve even higher speeds, no matter the motherboard you're using.
You can observe from the image that it is activated and running at 1866mhz, yet it behaves as if it has a specy CPU-Z and the BIOS indicates 1600mhz.
Ah, I didn't notice that. With XMP at 1866MHz and DRAM in auto mode, it displays as 1600MHz? That's quite unusual. The only condition for exceeding 1333MHz is a 22nm chip, which the 3570 supports. Do you have the most recent BIOS version? Either 1.A or 1.9?
Unless it's another designation for what's labeled "1.A", there isn't a 1.10 available for that board.

To be honest, I'm not sure. The faster speeds could be restricted to unlocked "K" CPUs since technically, exceeding 1333/1600MHz is an overclock. However, this restriction typically applies only to speeds above 1866MHz.
