PC starts a booting process then shuts down and repeats

[3nok1]

so I ran into a problem today. After I installed everything into my new case and some new parts. When I went to change my ram speeds and save it to 3000Mhz my PC enters a boot attempt then shuts down after a few attempts it boots correctly and for now it’s stable but it locks the ram speed to 2133Mhz. The new parts are the 2 Corsair RAM sticks, a new SATA SSD 1 TB, a Noctua fan and a wifi/Bluetooth extension card.

build:

CPU: AMD Ryzen 5 2600x

Ram: 2sticks Kingston HyperX fury 8gb ddr4/ 2sticks corsair Vengence RGB Pro sl 3200Mhz 8gb

PSU: 650W bronze

Graphics Card: Nvidia RTX 3060ti

theoretically, I shouldn’t be having this issue because I installed 2 new RAM sticks an SSD and a fan

Update: it was the corsair ram sticks causing the issues. tested them individually and only they made the problem accur

The RAM is not appropriate for your CPU, AMD state here up to 293300MHz and if you have XMP or DOCP enabled the RAM will get auto OCd past what the CPU can handle and the PC will fall over.

for now it’s stable but it locks the ram speed to 2133Mhz. T

Modern RAM has two speeds, SPD (serial presence detect) and XMP, SPD is what the BIOS detects on boot which for DDR4 is most often 2133MHz and XMP which when enabled will set the RAM to run at the maximum speed that it is capable of.

It is enabling XMP that is causing the issue, manually OC the Ram to 2900MHz, save the settings, restart and see of the RAM runs stable, repeat the steps until you get to 2995MHz or so.
