How to increase the speed of your DDR4 Corsair 2400MHz RAM.
How to increase the speed of your DDR4 Corsair 2400MHz RAM.
I've adjusted my Corsair LPX DDR4 2400 to 2666 with the same precise clock speeds as the original 14-16-16-16-31-1T, passing all memory tests at standard voltages on RAM. Also tested on a Ryzen PC.
On the MSI B350 Mortar Arctic
MSI GTX 1080 Armor OC
2x 8gb Corsair Vengeance LPX DDR4 2400 @2667 1.2volts
Results may differ, but most users have achieved solid overclocks on RAM as well. I'm targeting ddr4 3000 with timings set to 17-18-18-18-36-2T, though stability remains inconsistent across different voltages.
I also possess Corsair LPX DDR4 2400 CL 14 1.2V, which I have overclocked to 3200MHz CL16 1.35V.
My system is an Intel Z270.
CPU-Z data shows:
Total Size 16384 MB
Type Dual Channel (128 bit) DDR4-SDRAM
Frequency 1600.5 MHz - Ratio 1:24
Timings 16-18-18-39-2 (tCAS-tRC-tRP-tRAS-tCR)
Slot #1 Module Corsair 8192 MB (DDR4-2137) - XMP 2.0 - P/N: CMK8GX4M1A2400C14
Slot #2 Module Corsair 8192 MB (DDR4-2137) - XMP 2.0 - P/N: CMK8GX4M1A2400C14
On my own with this RAM, I can reach 2666 without any adjustments and have progressed as far as 2800 at 16-17-16-39 while maintaining stability and no voltage rise. I had to reset the CMOS once when trying for 2933, possibly because it required a slight voltage boost and the timing needed to adjust more. I experimented with settings like 18-18-18-42.
I also own Corsair LPX DDR4 2400 CL 14 1.2V and it reaches 3200MHz CL16 1.35V.
I have an Intel Z270 system though.
Check the CPU-Z results in my post:

How did you achieve this?
My X299 isn’t even post with these settings.
Anyone else experienced in boosting this RAM to 3000/3200 MHz???
if your base RAM speed is 2400MHz, then u wont get it to 3000MHz, simple. Also, why do you need 3000MHz. A 2400MHz CL13 will smash a CL15 3200MHz. Just stick with 2660MHz, and use DRAM timings like this. CL 13, 16, 15, 15, and 35 in that order. It there is another one at the start, set it to AUTO and turn off XMP. RAM speed doesn't really effect anything because there is a certain point where the CPU wont be able to read the information as fast as the RAM can send it. so 2400MHz with a low CL is a way better choice and is cheaper.
