[SOLVED] Memory timing if frequency is downgraded

[simptive]

I found that in DDR4 rams, most 2666Mhz have 19-19-19-43 timing while 3000Mhz and 3200Mhz have 16-18-18-38.

Since my chipset doesn't support 3200Mhz, memory fallback to 2133Mhz. If you enable XMP profile, it increases frequency to 2666Mhz.

I want to know that, Does a 3200Mhz memory with 16-18-18-38 timing runs at same timing if chipset supports only 2666Mhz speed?

No, timings go with memory speed, typically higher frequency requires higher latency for given RAM.
Use CPU-Z to see what timings go with different frequency. JEDEC as well AS XMP, it's all written in your RAM control chip.
