[SOLVED] PC resets BIOS afters OC SOS

[Zeplyn]

I recently moved and brought my pc with me, and ever since as soon as I overclock my cpu (R7 1700x 3.9 ghz) and ram (2x8gb 3200mhz) from stock settings it does a double reboot and resets the bios. Any help on how to diagnose/fix the issue would be appreciated mobo msi b450 tomahawk psu 650 W gold cooler H100i

Which issue? the crash/restart with an overclock or the resetting CMOS (BIOS)? There's a setting in BIOS that should tell it not to reset CMOS on failed boot up, but I think you want that to happen for now at least.

Does it reboot immediately? or after a while of operating? The movement could have dislodged the water block/pump so it's not cooling the CPU well. In which case, remove, clean and reapply TIM.

What VCore voltage are you running the processor? 3.9Ghz is pretty high overclock for a 1700X so it usually needs some increased voltage to stay stable. I'm not sure why just moving could affect it but you might need to increase it.

so it does the usual restart after saving changes then it restarts again and one more time before resettings the bios Its not the cpu as it runs stable without the OC ive been running it at 3.9 for a while and havent had any issues ive always set the voltage to auto....... New change ive noticed half of my RAM is hardware reserved no matter where I slot them or swap them out? Thinking the move might have damaged my MOBO.... Any suggestions?

Update looks like RAM slot is broken.... tried sticking both the dimms in opposite slots, no hardware reserved but wont oc.... when I only use 1 dimm it overclocks with no issues..... Looks like im gonna have to sell the RAM and buy 1 stick with equal capacity any other suggestions

Firstly: are you using the correct slots? usually the second and fourth (last) slot going away from the CPU.

Secondly: for a Zen 1 CPU (1700X) 3200 is really a pretty steep overclock for memory and generally requires some tweaking to get stable. I'd try to bump up DRAM voltage for starters: start with 1.35V and increase a notch at a time. DDR4 DRAM is rated for 1.5V but don't go higher than 1.40V. If that still doesn't get it stable then try lowering multiplier to 3066 then 3000, 2933.

If it gets stable at least you know the real problem: that you need to tweak timings to get stable. You can get something called DRAM Calculator along with Taifun Burner (to determine the precise DRAM chips your DIMM's have). Once you know the precise DRAM chips, DRAM Calc will help by calculating all the correct timing and voltages to try to get your memory stable.
