Downclocking
Downclocking
My ram is a Corsair Vengeance 3200MHz 8GB one. It functions as an XMP module. Should I turn on the XMP feature, which sets the speed to 3200MHz, and then manually select the 2933MHz option to downclock it? That seems acceptable.
Seems alright. Of course, you can also downclock and undervolt manually, but if it's rated for 1.35V, then I don't see why you would do so. Except if you want to tighten the timings. Then push the timings up 1 or 2 steps and see how stable it is. The rule of thumb is for every clockspeed tier you move up, timings go down...
When I turn on XMP, it automatically adjusts the RAM speed to 3200MHz. However, there isn't an XMP profile for a 2933MHz speed. So I enable the XMP option and then manually set the RAM speed to 2933MHz while leaving the rest of the generated XMP settings unchanged. Is that acceptable? Or should I adjust the voltage and timings instead? My RAM is rated at 1.35V.

So for instance, if your RAM runs at 3200 CL17, you can do 2933CL16.
Furthermore, if it's stable at 3200Mhz and X set of timings, there shouldn't be a reason why it won't be stable at same timings and lower clockspeed.
