Over clocking my CPU Makes RTX 3080 TI Stop Working

[Wolfarix]

Hi everyone I’m having some trouble with my PCand was hopping someone can help me. My specs are,

Ryzen 7 5800X

GTX 3080 TI

32GB of 3200mhz RAM

1000W PSU

 

i just got an RTX 3080 TI and found out that the card doesn’t work when the CPU was slightly overclocked. I have an ROG motherboard and I used Asus’ optimize wizard to up my CPU performance a little. But unless the BIOS are set to default the card will not run. I thought it was a power issue so I went out and got a 1000W PSU but that didn’t seem to fix it. And to be real sure it wasn’t a power issue I rigged it so that the GPU had an independent 850W PSU separate from the system and that still didn’t work. Is there anything I can change in the BIOS to make this work? I don’t want to run the CPU at default settings because I would be leaving performance on the table. Hopefully someone has the answer to my problem.

Ryzen 5000 series are pretty close to maxed out, like 95% potential out of the box. To squeeze that 5% out you need more effort than using a noob 1-click program (that probably pushed something above safe levels). Easily a whole weekend worth of time into manual tuning is needed since memory overclocking plays a big role.

 

I'm not sure what Asus thing did. If it raised BCLK then it's possible to cause the graphics card to stop working, but I hope it didn't do so because the worst from this is corrupting NVMe SSDs. Or the overclock could simply be so unstable that nothing runs, not just the GPU.

for CPU nowadays, not really

 

did you make sure that it's the 3080's fault by using other GPU or?

i guess one thing you can try is switching to PCIE 3.0 instead of 4.0

Ya I used a GT 720 for troubleshooting purposes and before I got the 3080 I had a 2070 Super in there with no problem.

this is certainly odd, try switching to pcie 3.0 as i suggested

That didn’t work.

do you know what specifically is being changed when you OC the CPU?

Looks like the BIOS set the CPU core ratio to 41.00 and enabled launch CSM.

just these? no changing bclk like @Jurrunio suggested?

I don’t do much manual overclocking. What should I set that to?

ideally it should stay at 100, which is the default as i understand

 

not too into CPU OC myself

Well I figured it out. I reset everything and only set my memory speeds to 3200MHz and the CPU is set to stock. According to UserBenchmark the cpu is now running way above expectations and the gpu just needs a little more tweaking. Thanks for the help.

it probably has touched the BCLK then since core ratio goes above 41 all the time at stock
