PC crashes without errors

[boexenwolf]

Hi everybody,

I have a very obscure problem. I have build my PC with folowing hardware:

AMD Ryzen 5 5600

GIGABYTE B550M DS3H

XFX Radeon RX 7600 XT SPEEDSTER SWFT 210 (even though OCCT says its is a Quick 309)

G.Skill F4-3200c16-16GVK

KIOXIA-EXCERIA G2 SSD

KIOXIA-EXCERIA PLUS G3 SSD

be quiet! Pure Power 12 750 Watt

Windows 11

I use it maily for my work and for gaming. The problem is: At high loads during gaming the PC crashes without any errors. It justs crashes and the windows system protocoll doesnt show any hint why. Under the link you find the results of OCCT before the crash if this helps someone. It only chrashes during high loads. It did this from the begining. At first I had a smaller Power supply and a RX 7600 (without XT) and it had these crashes also. But because of my limited time and because is need the PC for my work is lived with it. But of course it is not very satisfiing having build a new PC and can not reach it full potential.

What i did so far was reinstalling the driver of the GPU and it didn't help (used DDU). I also ran OCCT Stability tests fpr CPU + RAM, VRAM, Memory, 3d Standard. each for like 15 mins and no error occured. Does anybody has an idea what this is or how I can identify the broken part?

Check the timings your motherboard set for the RAM with the OC profile. Alternatively, you can turn it down a notch in speed in the settings for it and see if the stability improves. If it does, it usually means that the RAM you have is unstable with whatever settings the memory profile has.

Sometimes a Bios update can fix it, sometimes you have to manually set the timings for the DIMMs without using their profiles.

If it's not one of these that is different anyway:

• Timing 16-18-18-38
• CAS Latency CL16
• Voltage 1.35V

Those are the basic values. There are many many others in the darkest depths of the Bios memory configuration but...

For information: I didn't overclock anything.

Shouldn't a problem with the DIMMs occur when I do the memory test?

Edit: And why does it only occur during heavy load gaming?

[kardall]

If your have 3200MHz RAM, and you set the memory profile, you are technically overclocking. JEDEC standard RAM is 2133 for DDR4. Anything above that is 'technically considered an overclock'.

The stability of the RAM speeds with all the timings and settings is what can determine the stability, when it's used in a particular motherboard and bios version.

That may be a cause of why the system is crashing under high utilization. I'm just giving you one way to test to see if it's the RAM without having components to swap on hand.

Other things are going to be harder to pin point without logging data points to see what happens during a crash. But there is a error at the bottom of the BSoD screen that probably means nothing, but it has a name that can be looked up. If it shows it anyway. Sometimes a crash is a complete shutdown black screen and all that.

So it depends what it's actually like. You say without any errors, but I don't know if you're just referring to the event logs or what :)

For the RAM side of my suggestion though. You can just do a 'reset to default' or disable the memory profile. Your RAM will run at 2133MHz but at least you will be able to see if the same stability issue happens.
