XMP is not like an old-school overclock. Assuming the motherboard isn't faulty, you're pretty much guaranteed to get the clock speeds advertised with no instability. It's plug and play.
- superkuh 4y agoIt is supposed to be plug and play but a good fraction of the time it is not. I've been assembling computers from parts since the mid-90s and I never had any trouble with RAM till my latest builds with DDR4 trying to use default XMP settings. In fact I've never gotten a DDR4 computer to run at the advertised XMP speed and timings even when the mobo fully supports it. I always have to back off a few hundreds of MHz and loosen the timings to prevent memtest86+ errors. I've observed others on IRC computer hardware channels reporting the same problems (selection bias, of course, only people with problems ask questions). You've been lucky (or you're using latest and greatest mobos).
- toast0 4y agoI've had good luck with DDR4 and reasonable speeds working with XMP, but sometimes the XMP data has a voltage lower than what the packaging indicates, and setting the voltage according to the packaging works a lot better. But I'm just getting DDR4-3600, not DDR4-5000 or something; and I think all my DDR4 setups are 1 dimm per channel, which helps. I didn't ever get DDR3 XMP to be happy though.
