RAM 3000mhz cl 15 overclocking
Hello, I own two HyperX Fury RGB 8GB DDR4 3000MHz CL15 units and I'm aiming for a minimum of 3200MHz at around 15CL. I've been testing them several times using the DRAM Calculator. My system specs are: CPU - Ryzen 5 3600x, RAM - MSI B450 Tomahawk (last BIOS, beta), Power Supply - Corsair TX750M. I used the DRAM Calculator settings and Thaiphoon's information from https://prnt.sc/wnaw4n and https://prnt.sc/wnarq8.
The issue is clear: at 3200MHz, FCLK 1600, Command rate 1T, BGS disabled, BGS alt enabled, Gear down on, Power Down off, it doesn't boot into the tCL14 that appears in the DRAM Calculator. It does boot if I change to tCL15 instead. However, according to the BIOS and Thaiphoon's notes (links provided), it still shows CL15 and 3200MHz at 16CL. The voltages match the recommended values, and the XMP profile is off.
I'm seeking advice on how to achieve at least 3200MHz and possibly 15CL. Please let me know if you have any suggestions.
Generally, a smaller CL value reduces latency and improves RAM access speed – ideal for most applications. A higher clock frequency speeds up data movement, making it suitable for tasks involving large data transfers, game level loading, and similar operations. Currently, your RAM module has an XML/DOCP of 3000 MHz with CL15. For optimal performance, start by lowering the CL number as much as possible, aiming for CL14. Once that’s achieved, increase the clock speed to 3200 or higher. Although Hynix RAM chips may not reach 3600, you can attempt at least 3200 or even 3466, maintaining a command rate of 1T.
Not every RAM would respond correctly no matter what you attempt. Even if you manage it, you might not notice any change unless the CLR needs to be adjusted. Regardless, consider using a higher voltage—ideally at least 1.35 volts, preferably more—that often makes a difference.
These RAM modules don't seem to be the top choice in silicon lottery. If they won't reach over 3200/CL16, it's probably best not to buy them. Still, you can use them at 1T.

If your CL remains above 15, a CL16 at 3200 should still be a solid improvement, offering faster data transfers without increasing latency compared to the 3000 CL15 setup.
There will be no significant variation between 3000 @ c15 and 3200 @ cas 16 (both are equally effective), so I would choose the one needing the lowest voltage.
