Hey guys,

I just updated my mobo to the latest version 190. After the update i was able to get the ram to 2933 mhz but after i restarted my cpu it went back to 2133 mhz? Does anyone know why it does this? I haven't overclocked my cpu yet, could this be the reason why the ram resetted?

cpu: ryzen 1700
gpu: r9 280x
psu: evga 550 g2
ram: g skill 4 series 3000 mhz
mobo: msi tomahawk
cooler: noctua nh d15s

Honestly idk why you'd bother for the gains, but if it doesn't stick at 2933 it's because it's unstable at the speed.

Your RAM speed doesn't change until your PC restarts. If it fails to stay at that speed and pass CPU tests then it will reset back to it's old speed and your PC will boot at old clocks. 2933 is too high for your voltages, RAM and/or mobo. Parts will not change that at this point. With borderline stable 'trophy' clocks, it's quite common for you to have to restart the system a few times to get a stable cold boot.

RAM overclocking is actually harder than CPU overclocking. It's much more temperamental and you need to understand timings to lengthen them appropriately. Too long and you lose performance with more mhz, too...

yes i did save it. But when it reboots the second time it reboots like 5 times before turning back on in which it resets the ram at 2133 mhz. I did turn the xmp profile to 2 which set it at 2933 initially

RAM overclocking is actually harder than CPU overclocking. It's much more temperamental and you need to understand timings to lengthen them appropriately. Too long and you lose performance with more mhz, too short and you get a poor overclock. Real world gain either way is sub-1%. The randomness of FPS variations when you repeat benchmark tests will be bigger than the gain you get. You'll be very happy with a 1 FPS increase.

To make matters worse, you shouldn't be able to get the best clock you've seen. Not even close. You shouldn't be trying to either. Overclocking, like it or not, is burning your parts to make them faster... they die faster too. When you start raising voltages, (which you would to get anywhere near a 2100-2900mhz size clock increase), you WILL over volt the chips and burn them out pretty fast. The only reason they are sold as 2100mhz chips in the first place was because they were tested at the lab and found to burn at 3000mhz. The ones that didn't went in the 3000mhz kits.
