Hi

Have an issue with my new AMD build that I am hoping you can shed some light on


Using...

CPU: Ryzen 3900X
Mobo: AsRock X570 Phantom Gaming 4
RAM: Crucial 1 x 32 GB DDR4 2933 RDIMM
PSU: Corsair HX1200
GPU : Nvidia RTX 2080
After assembly as per instructions...

  • the unit powers on
  • The GPU Powers up
  • The fans on Case, CPU & Mobo all working
  • There is no image on the monitor whatsoever
  • The Post status Checker on the Mobo shows - the CPU & DRAM LEDs solid red immediately & continuously
After 30 secs the system switches off and reboots again, same 30 sec cycle repeats

The CPU & Cooler are mounted as per instructions

The Ram Stick is in the A2 Dimm slot

The Mobo 24 pin ATX cable is properly connected

The Mobi CPU 8 pin +12v cable is connected to the last adapter socket on the +12v [middle] rail of the PSU [centre far right] & the PSU selector switch is set to single

Hope you guys can shed some light on this

Thanks in advance
Zakk

It sounds like the motherboard is failing during memory training and is likely your issue...

2 x 16gig of 3200 to 3600 fast memory is what you should be running.

The sales guy assured me it was compatible [so he has to wear that if it's not]

The board maxes at 128 GB memory so needs to be a 32GB dimm

When I was checking the motherboard recommends trying to find solution I did notice that no 2933 speed dims were listed in the list.. at all, which I thought was odd.
Nope. Not compatible. Return and get 2x16GB for better performance. Un-buffered, non-ECC memory. As fast as you can afford.

Been sorted as we speak and I have given the sales guy [a corporate] a burn as I specifically asked him to verify component compatibility before he sent it to me

Getting 2 x 16 GB G-Skills that actually state optimized for ryzen 3000 series & the X570 mobos

Annoyed as getting 16s means I can't utilize the Mobo's 128 gb ram capacity which require 4 32's to get that.

At least this step through system should keep me happy until the 64 core threadripper comes out in Jan / feb - I'll have a full 256 GB Ram attached to that.

If you wanted 128gb you should be buying a 128gb kit. Mixing RAM from separate kits is not guaranteed to work without issue especially when using all for DIMM slots.
