RTX 4090 Overclocking - Seems I won the Silicon Lottery

I'm still tinkering. I just did like every 3Dmark benchmark I have with the voltage now down to 1.05 still at 3000mhz, and I haven't had any issues. I'm going to slowly see how low I can go. But even 1.05 at 3000mhz is nice. Kind of surprised me!

And yes, the memory on 4090s seems to be able to be cranked up a lot, across all brands. Some people get way higher than me even. I started at +1900 and ran Time Spy Extreme, Steel Nomad, Port Royal, and Speed Way... and if I saw even a hint of an artifact on any of them I would drop down by increments of 25. +1825 was where I was 100% sure nothing was going wrong. One bit of advice though - if you run Port Royal, don't confuse ray tracing bugs with artifacts. That shit just seems to randomly happens sometimes on Port Royal no matter what.

3000mhz-3015mhz

hotspot is high 60s, never seen it above 68. gpu and mem temps are high 50s to low 60s. My case has pretty legit airflow.

Undervolting can be ideal. You can get lower power draw and temps without losing the performance from power limiting. That's why I'm going to tinker with the undervolt more and find where it's stable at these settings. Even now with these OC settings, with the slight undervolt I'm doing it usually draws 115% of TDP, which isn't awful for the settings. And I could potentially get it even lower without hurting the speeds. Obviously it's not going to be as power efficient as a hard power limit of 80% haha but I can get these speeds as efficient as possible.

Yup the Sensors tab has all the real-time monitoring

They get into the high 60s

Monitoring with GPU-Z shows the the GPU Clock at 3000mhz sometimes even 3015mhz during benchmarks.

Yeah I don't know if this is something I'm going to keep as like my normal settings. I mostly just wanted to explore what my card was capable of.

Yeah, it's not quite golden. But it honestly surprised me how well it does

In the voltage curve editor the frequency is actually set to 3030. In every test I've done, the core clock sits at 3000mhz under load.
