If this still doesn't work, I will try downclocking to 3133mhz and tRC 55 as per a previous post in this thread or run without XMP at 2133mhz. This was me and I wanted to share my experience too, since the problem seems to more widespread than just me. It's a theory that may seems reasonable but I cannot confirm for sure in any way and would be interesting to understand the difference.

Most higher clock RAM is B-Die from the QVC I read for my GB z370 Gaming 7, though this conclusion could be a suvivor bias for all I know. This translates into snappy responsiveness and smooth multitasking, which are crucial for gaming and content creation. Originally it did get off to a worrying start as there was an issue with the product and didn't know if it was us or what.

With dynamic multi-zone RGB lighting, each module boasts 10 vivid RGB LEDs, transforming the look of your setup. If anyone is interested you can see my tightened timings and overclocks for this memory kit in the corsair thread link below. Its not detecting it the right way, The stick on the right shows LEDs glowing down, But the one on the left shows it going up, The display in ICUE shows both going down, Kinda dumb if you ask me. I have just tested for a couple of days but my impression is that when XMP is off and memory is at 2133Mhz it is stable but I would need further testing.And last but most importantly, make sure the RAM is slotted in DIMM A1 and DIMM B1, or DIMM A2 and DIMM B2. Installation was a breeze; the modules fit snugly into my motherboard, and XMP profiling worked flawlessly to achieve the advertised speeds without any manual tweaking required. After switching XMP to auto, the tRC parameter is set to 64 in bios, but in windows alone it sometimes shows higher even over 70.

The memory modules are rock-solid performers, with a clock speed of 3000 MHz and a low CAS latency of C15.

The icing on the cake is Corsair's next-generation iCUE software, which lets you take reign over the lighting while syncing with other Corsair RGB products.
