I can't post after overclocking my RAM.
Are you using XMP or adjusting the speed manually? I'm confused about why turning the switch on your PSU switches it from posting to not posting. It might indicate a problem with the PSU. Also, RAM can be quite sensitive. Just because RAM is rated for a certain speed doesn't guarantee you'll get that speed.
I'm doing it myself since I recently boosted my PC's clock speed to 5ghz, but I'm having trouble adjusting the RAM speed.
Did you adjust the BCLK during your CPU overclocking? That can affect your RAM as well. I don't suggest changing the BCLK when you alter the multiplier from 100, because the calculations become unclear.
Your BIOS already has an XMP profile configured. Just enable XMP and it will automatically overclock your RAM without needing any frequency changes.
If you encounter issues with XMP, revert the system back to factory settings in the BIOS. The option to enable XMP as the OC might be interfering. After restoring, try the overclock again.
For example, with a 7700k processor, I achieve 5ghz at 1.34 volts. You can adjust the multiplier to 50 and set the voltage accordingly for optimal performance.
Have you attempted to remove the OC from the CPU and then activate XMP? I was considering this step before discovering the RAM issue.
If you can't get your RAM back, I won't be too concerned. The speed difference won't be significant with your 7700k.
