Does 3200mhz RAM work with a 2400mhz motherboard?
Does 3200mhz RAM work with a 2400mhz motherboard?
I have an Acer TC-780-ACKI5 Desktop PC with 16GB RAM (2 x 8GB) at 2400mhz. I'm considering upgrading to 32GB RAM, but the motherboard only supports that. There are also two 16GB 3200mhz RAM kits available for $20 less than the 2400mhz version. I’m still comfortable with my current setup, but will the higher speed RAM cause a bottleneck on a slower board? I just want to avoid buying something that might cause problems without a clear solution.
This one seems to be a specific model. The memory controller is built into the CPU and the 7th generation supports speeds up to 3200MHz, but the main issue might be a custom BIOS lacking XMP support for that frequency. The most likely outcome would be it only reaches around 2400MHz.
Exactly that choice is right, even if it slows down a bit, it's still better than the other option because it's more affordable.
For 7th generation Intel cores, RAM operates at 2133mhz/2400mhz settings. Increased RAM speeds need overclocking capabilities on the motherboard, which are available only with Z170 and Z270 chipset boards. It's unclear which chipset is present in the Acer TC-780-ACKI5; it might not be a Z series model. You can verify this using CPU-Z in the motherboard section. Edit: The chipset appears to be H110, meaning ram overclocking isn't supported.
Typically DDR4 RAM operates in two modes. The standard JEDEC speed (2133/2400MT/s) and overclocked settings like XMP/EXPO/DOCP are available when the motherboard supports them. You should be able to run 3200MT/s RAM without issues at the default JEDEC rate of 2133 or 2400MT/s. To verify RAM speeds, use RAM speed tables found in the SPD chip on most DIMMs with tools such as CPUID, Aida64, Speccy, etc.; Aida64 works well for me.
So I installed the new ram and am sure I should tweak or modify a few configurations since my system only shows 16 gb in task manager and bios but cpu-z displays the actual capacity. There might be a bios setting or update required to recognize the full 32gb.
