Just got this MSI RTX 3080 TI SUPRIM X and would like to know other users experiences with 2 topics:

1) MSI Afterburner - OC: want to understand what are the best overclock profiles. I have an AIO. Current OC setup:
  • Core Voltage +50
  • Power Limiter: 110%
  • Clock +150 MHz Dynamic GPU clock 2050~2100 MHz
  • Mem clock +1000(=2.1 Gbps effective)
  • FAN RPM default
2) Fan curve: I had a fan curve on my MSI 2080 ti gaming x trio in the past. Has anyone checked if anything different than default fan curve RPM is a good thing?

Thanks in advance.

Also in terms of BIOS I didnt see an update so maybe the current one is the best / Latest. Should I try another bios?

bios V. 94.02.71.40.15

Don't raise the core voltage in Afterburner. What you want is an undervolt combined with a slight overclock. And don't do it by using Core Voltage, set a custom voltage curve. The reason is, NVIDIA are already quite aggressive with their voltage-per-frequency curves, in order to beat certain AMD cards. So you can't brute-force an OC on top of that, you will just destroy the efficiency completely. What you do is, you undervolt a bit and see if you can eke out a nice little overclock at the same time. That's by the far the best way on these cards. Otherwise, the heat output will skyrocket and the fans need to do overtime.

Here are a couple guides about this:

Thanks for the guides. I will check those.

And what about your experience with custom fan curve for this card?
Also, the bios is the current one? the version I wrote? thanks

I don't have the same card, i have a much smaller GeForce. But the process about undervolting and overclocking is always the same.

As for the fan curve, you will find that when you undervolt the GPU using a custom voltage-per-frequency curve, the power draw will increase quite substantially under load, and therefore the fans don't have to run at such a high RPM either to get rid of the heat.

I even made an "extreme undervolt" profile for my GeForce, something you can see here at 13:45 mins:


That is useful for older games that run with well over 60 fps even with the GPU quite undervolted and underclocked, for example my GeForce 3050 can run at 1500 MHz @ 700 mV (700 mV or 0.7V is the lowest that the curve editor allows). This limits the power draw to under 60W (!) while still achieving completely smooth gameplay in some older titles. The fans barely turn on with that profile, they stay at 30% speed which is very quiet.

Undervolting your card will have a big impact, because it's so power-hungry, so there's a lot of power draw to shave off.

@moderator, close this one as well since it's not an issue with overclocks or anything. I only need one, updated thread and not multiple ones
