Yes, it is possible to reduce RAM speed depending on your system settings and requirements.

I purchased an older motherboard G41T-R3 from Ecs and paired it with a 4GB DDR3 stick at 1600MHz. After assembly, it failed, so I replaced the stick with a 2GB model at 1333MHz which worked. The board’s specs indicate RAM support only up to 1333MHz or lower. Can you adjust the 1600MHz stick to run at 1333MHz?
You purchased the incorrect connector, the socket 775 only supports 2GB single-sided (meaning all chips on one side) and 4GB dual-sided (both sides). The 1600MHz speed is quite recent, so it's likely you bought a 4GB single-sided stick, which this system can't handle. The issue isn't the frequency—your board will automatically slow down anyway.
By default, systems use the fastest RAM speed allowed by the CPU or platform. You won’t get faster performance unless you adjust it yourself.
