Why can't I set RAM settings in bios?

Question

Iron

In general, I decided to overclock the memory, went into the BIOS, set the frequency, timings, voltage, restarted ... The PC started up after several attempts, I realized that something was wrong. The frequency has not changed, as well as the timings and voltage. Well, I thought "I did not lose with the frequency or timings." But after several futile attempts to somehow change the memory parameters, I received a reset. I even set the frequency lower, the voltage, the timings, nothing changes in any direction and is dumped into the drain. The mother supports overclocking up to 3200. The PC always started several times after the changes and everything was reset. And yes, xmp profile doesn't work either... Has anyone had this problem?

Answer 1

Judging by the forums, this is a characteristic feature of these modules. The fact that these modules are sold only individually plays a role, which carries the risk of a conflict between the two dies. And Ryazan Zen + still has not completely got rid of the specific flavors of RAM.

The main thing. What for?
