You have two memory modules installed, each operating at 2400 MHz. The SPD profiles indicate these sticks can function at CL17 or CL18 (Jedec #8 and #9). To maintain the 2400 MHz frequency, any additional sticks must also operate at this speed. Higher frequencies are possible but will still run at 2400 MHz, matching the slower sticks' speed. All modules will adhere to the timing supported by each other. Timings may decrease if the frequency drops—for instance, a 3000 MHz stick with CL16 might default to CL15 at 2666 and CL14 at 2400 MHz. However, combined with your existing sticks, the motherboard will set timings to CL17, which is the lowest supported by your older modules at 2400 MHz (1200.5 x 2). You could consider a 2666 Mhz stick with CL19, which would run at 2400 MHz at CL17 or CL18. Alternatively, you might upgrade to a 2666 Mhz stick for better performance and future flexibility (if your CPU and motherboard support it). Other options include: https://www.amazon.in/dp/B072QYHKLR
Avoid purchasing 4 GB sticks; opt for 2666 or higher. Get one 8 GB stick—it pairs well with your two smaller ones. When you have extra funds, sell or trade your two 4 GB sticks to acquire an additional 8 GB stick. 4 GB cards offer low resale worth, and 2400 MHz chips usually use inferior memory modules that have failed tests or can't handle higher speeds, making them unsuitable for overclocking. This means few buyers will be interested, resulting in low resale value.
