No Display Output/Booting Issues

[Fieryawesomeness]

Hi, I'm a relatively experienced PC builder and tinkerer in need of some help.

 

A little while ago my PC had an issue where it would not start the boot sequence, but fans would spin and all RGB things lit up. This came after doubling up my RAM capacity and fitting braided PSU extensions for my GPU and MB. Naturally, I removed these, but the issue still remained. After ruling out components, I was eventually recommended to open a warranty case with AMD for my CPU. The CPU was replaced under warranty. The MB was also replaced under warranty. After changing my RAM timings to those listed on the sticks, everything was working great with 4 RAM modules. This was around 6 months ago.

 

Then, last night, the same thing happened again. PC was on, idling, went downstairs, came back up, and my monitor was on standby with a black screen :(. Slamming my head into the keyboard didn't help, neither did furiously shaking the mouse. However, all my RGB setup was showing the correct colours, and I was able to change between lighting presents on my Razer keyboard.

 

Restarting my PC with the power button, lights and fans would all work but it refused to POST, so I am not able to enter BIOS, just like the first time. Afraid I had somehow blown up another CPU, I tried re-seating my CPU in the socket. To my luck, it booted, loaded into Windows, but after a few minutes the screen went blank again and I was back to square one. Any help/advice would be massively appreciated here. My specs are:

 

OS: Windows 10 Pro

MB: Gigabyte X570 Aorus Elite

CPU: AMD Ryzen 7 3700x (w/ stock cooler)

RAM: 4x Corsair Vengeance RGB Pro 3200MHz CL16 8Gb

GPU: Gigabyte Radeon RX5500XT OC 8Gb

SSD: 2x Samsung 970 Evo Plus 1Tb

PSU: Corsair VS550

*UPDATE*

After resetting CMOS, PC now running fine. This leads me to believe it's once again an issue with memory timings.  RAM currently running at 2133MHz, with the timings in the picture attached.

 

Now in working order but I can't seem to get it to work at 3200MHz with manufacturer recommended timings.

 

I am able to run 2 modules at full speed, but I can't see how after 6 months I'm suddenly unable to run 4 modules at full speed...

What voltage are you running the ram at? 

 

They might need a bump in voltage to keep running at that speed. 1.375 for instance.

 

Also make sure you have enough airflow for the ram. Crowded together like that, they can get got.

I'll check tomorrow, but pretty sure they're running at 1.35V from memory, so thanks for that, I'll give it a go. My case has 6 fans, so I don't think airflow should be an issue... But what kind of temps should my sticks be running at?

Although ddr4 specs dictate that it can handle temps up to 80c, I've seen many start system stability issues around 40-45c. Any form of ram it's really cooler is better (sub ambient becomes a different story however). 

 

Air flow in the case is necessary however air can stagnate easily with just two sticks, four sticks and air flow by the sticks can be nearly non existent. This may not be your issue, but it's something to be aware of.

This is super helpful, thanks very much!
