Odd ram behaviour

So I've been running my Corsair Vengeance RGB Pro at it's rated speed of 3200MHz happily for a number of weeks in my 2700X system, Turn on the rig today and for some reason after 20 minutes of answering emails my system freezes, I turn the power off, Boot it back up, Go into the bios, Redo the settings and for some reason it will not go past the boot screen now.

So I tried lowering the speed down to 3000MHz, That worked for 5 minutes and then it happened again.

Now I've flashed back to a much earlier bios, Lowered the speed to 3000MHz from its rated 3200MHz and it's been stable for hours, It's really odd that it would be stable on a specific bios for weeks and then all of a sudden become unstable.

I haven't a clue what's going on, Any insight would be appreciated.

EDIT

Flashed back to the bios I was using earlier and 3000MHz is completely stable but the rated 3200MHz I was running for weeks refuses to stick, Very weird.

looser timings?

Interesting Dice I can't get my 1700x to run 32gig of 3200 ram either it was blue screening but it's running quite happily with 16 3200 I wonder if it's Windows 1809

Nah, hardware problems aren't down to your OS, especially when it's about ram which has no drivers.

Thats incorrect. A recent update from windows prevented many users stable CPU overclocks. Removing the update returned stability to many people.

I installed the 3200MHz memory just after 1809 landed and it sat happily at 3200 for a good few weeks and all of a sudden it simply doesn't work at anything over 3000MHz, It's not that it won't boot into Windows, It won't even make it to the bios screen.

Maybe running it at 3200MHz was just a fluke

What do you do then at that point?...

Hold the power button down, Power off and it then reboots with default settings.

Have you manually set the SOC voltage?

Nope, Didn't know I should've to be honest, Worth fiddling around with ?

Thats the voltage that stabilises ram speeds.

Try 1.1v to start

It auto sets to 1.137 and honestly I'm fine with 3000MHz, All the timings are at their rated speeds but if anything gives I'll then start to tinker.

Thanks for the input Guv

I was getting an error 55 and my system wouldn't boot either, I had to clear CMOS then reset to default then enable AXMP then it worked for awhile then I kept getting BSOD's so took out 16 and away it went, even tried reformatting at first thinking it was that but you can't even install Windows with 32 you have to do it with 16 then put the rest in after..............
