PC Graphics

[Tomato33]

Hi,

I build a PC about a month ago with parts I picked out. Current setup is:

CPU: AMD Ryzen 7 7800X3D

GPU: GEFORCE RTX 4070

MB: ASUS TUF GAMING B650-Plus Wifi

RAM: Corsair Vengeance RGB 32GB (2 x 16) DDR-6400Mhz CL32
PSU: EVGA Supernova 850G XC ATX3.0
OS: Windows 11

I have been running into an issue where when I am playing games, even simple ones like Runescape or Rocket League my computer will either crash the game or spazz out altogether. Similar to other issues on here, there can be times when my computer won't crash for a day or so then randomly hit 2-3 crashes in the span of a couple hours. I don't typically have a lot going on (discord open and streaming, and games being played). It seems a lot of crashes tend to happen when I am tabbing in and out of games from one monitor to the other. 

I am unsure what kind of fixes I would need if they are related to the AMD CPU, Graphics, or RAM. I have updated BIOS(flashed them when I first built PC), set up OS, downloaded chipset drivers for AM5, graphics drivers have been updated and motherboard drivers are installed. 

Would i need to have both the AMD Radeon Graphics and NVIDIA Graphics included in my display adapters or are they potentially conflicting to where I should only use my RTX? I do not have adrenaline downloaded as I didn't think it would be needed since it kept asking me to set up a graphics card

--Should i disable AMD Radeon?

I am very nooby when it comes to new PC builds so asking for help if there is anyone who knows about most of this.

Thanks,

Temporarily disable EXPO/XMP and run the memory at default 4800 to see if that has any change in behavior.

Question, why would i change the memory to default 4800 if the sticks are for 6400? Genuinely curious, wouldnt i be losing memory performance i essentially paid for if that's the long term solution?

[FunkZ]

Because 6400 may be too much for the IMC to handle. 6000 is generally considered the "sweet spot" for DDR5 on AMD 7000 series.

It's an easy troubleshooting step to either confirm or rule out the memory as a potential problem.

[Tomato33]

Sounds good. I changed to 4800 based on your suggestion yesterday so i will see if that works out. If all seems well after about a week, I'll probably up it to 5200 or so as that's the listed max for 2x1r

Just like DDR4-3600 was recommended for the 5000 series Vermeer processors, DDR5-6000 is recommended for 7000 series Raphael. So you should be safe running 6000 but getting faster memory to work is hit or miss.

I've seen some reviews of the 9000 series claiming DDR5-8000 works but it's a little early to definitively recommend that.
