Overclocking RTX 3070 question

[EduarDoc]

Hello all,

 

I am new at this stuff of the overclocking. I am just a casual gamer but I find the 'thinkering' with voltages and frequencies interesting. I have been trying to overclock my GTX370 using afterburner but I feel like I reached a limit in this process. Everywhere I have researched increasing the power limit is important but my slider only goes to 100% and I have checked all the boxes in the settings.

 

I feel comfortable that I would be able to increase the limit comfortably because running Superposition benchmark I am hitting a comfortable max temp of 61C. With this settings I have been able to push the memory clock +900MHz and the corresponding Core Clock. When compared to others in the leader board it seems that I am reaching the memory frequencies limits but way below the average temps.

Does anybody know how can I 'unlock' the power limit? Did I hit the bad silicon lottery? Am I flying to close to the sun?

 

Thank you!

By GTX370, I assume you mean RTX 3070 right 

 

For some models, like the MSI Ventus models, you can't increase the power limit above 100%, as it's hard limited in the BIOS. You could get around this by flashing a different BIOS.

which 3070 is this?

Whoops. Yes, RTX 3070 (showed my newbiness ) and you are correct it is a MSI Ventus. Thanks for the tip.

Follow up question, for you or anybody who may know the answer. I use the GPU for image processing for research purposes (mainly medical imaging) does this overclocking process impacts compute and processing time, my intuition says yes since I am using the CUDA cores to process but all the information out there focuses on gaming performance. Which, by the way I do not complain about

Yeah it's not going higher with stock BIOS.

voltage was locked for me too until I recently updated afterburner. Went right ahead and undervolted the heck out of it,  lower temps, lower power consumption,  higher performance,  what's not to like !

 

ps: was greyed out for me too as said...  don't really wanna try  without some research anyways tbh since default power limit is at 270w already >.>

 

 

 

Also undervolting got rid of any 'PerfCap reasons' which is imo preferable

There would be a difference, but only a small one - maybe around 5-8% less compute time depending on the specific workload you are using it for. If you could theoretically increase the power limit to say 110%, then it would probably only really increase this by maybe a further 3-5% or so.
