No, memory timings don't have to be identical.
Hello, you're planning to upgrade your system by adding another 4GB RAM. Your current setup has an 8GB RAM module with timings of 15-15-15-15. For the new 4GB RAM, it's important to ensure compatibility in both capacity and timing. Since your existing RAM is DDR4, the new stick should also be DDR4. Check the manufacturer’s specifications for the new RAM model to confirm its timing requirements. You may need to adjust BIOS settings if necessary. To verify, look up the recommended timings for the 4GB module or use a memory test tool to ensure stability. Let me know if you need help finding the right specs!
It's suggested to purchase identical memory modules from the same brand and model. You can still modify timing settings if needed, but ensure you stick to the same brand and speed.
The motherboard will select conservative clock speeds that are compatible with both memory modules. Your current stick runs at 2133 Mhz, while a 16-15-15-36-50 stick would pair it with the same speed on the other side. Remember, your existing stick is only 2133…2400 Mhz, and laptop sticks in this range are usually affordable. You might find a 2400 Mhz model advertised as 17-16-16-36-50, but such a stick would come with a built-in preset for 2133, offering better timing options—possibly even 15-15-15-36-50. Timings change with frequency, and each memory module has its own preset. For instance, the 2666 Mhz GSKILL Ripjaws runs at 18-18-18-43-61 or 2222 Mhz at 15-15-15-36-51, so if you choose a stick like that, both modules will operate at 2133 Mhz with compatible settings.
