Undervolting/clocking the 3070 ti - requesting recommendations

[q974739]

For...umm....reasons, my nehew is being bought a 3070ti and I need to nerf it somewhat.

There are significant concerns that his previous card might have ebeen killed by heat - and I've been asked to undervolt/restrict the new card somewhat to try and reduce this risk. Could people please suggest a methodology/settings to achieve this, while still blasting the socks of his little 1080p heart. Not to mention his poewr supply is marginal, and preventing it pulling ALL THE POWER is probably just sensible!

Thanks

One thing you can check out is that Afterburner should be able to limit the temperature of the card.

use rtss that comes with afterburner and cap fps at his monitor refresh rate

I run my 3090ti at 90% target, got to save the penny's on electricity.

Buy him a decent case with airflow. Other than that. Cap his frame rate a couple fps below the monitor's refresh. i.e. 144hz cap at 141 or so.

did my 3060ti other day saved nearly a quarter on energy usage and boosted fps a touch, cant fault it, tbh i just googled it
bound to be a 3070ti vid somewhere

The only true method is power target decrease.

I used this guide for 3070 - works really well more FPS with a cooler and quieter card.

However I have since reduced my power limit further which substantially decreased my power usage and the perfomance hit isn't too great

Depends what you want with undervolting, I usually do it so it matches stock performance or slightly better with the benefit of lower temps and lower power usage

Don't like the idea of losing performance

You will need to test stability on various stuff

I undervolted my 3060ti - incredible reductions in power consumption of 25 to 60 watts (it varies) but at a constant 1920mhz on the core and low 60's temp @0.875v. I've not tried tweaking this yet - may try going lower.

The card will throttle itself if it gets too hot, there is nothing you can do to nerf the card that can't easily be undone or worse used to overclock the card. Buy a Zotac card with 5 years warranty and let him get on with it.

It should throttle enough, but there might be other issues as well and I think there's scope for a more efficient solution.

The OP mentioned the PSU being marginal. If so, it will be operating outside of its most efficient range and that's not ideal. It'll fail sooner. If it's lower quality, it might not remain entirely within spec when being overworked.

If overheating was a factor in the failure of the previous card, there's probably something suboptimal about the PC anyway. Airflow, PSU, whatever.

But even if the previous card's failure had nothing to do with overheating and the new card will throttle itself enough, that would still result in a reduction in performance. So in the circumstances I would be inclined to try undervolting the card so it will throttle less for the same power draw and the same heating, thus increasing performance. If I was concerned about the PSU being marginal and/or overall cooling being inadequate I'd probably both undervolt the card and reduce the power limit, accepting a reduction in performance (that would probably be less of a reduction than would have resulted from throttling for either temp or power draw or both). The OP also states that their nephew is gaming at 1080, so it's hardly likely to matter if they're using a 3070 Ti running at 90% of stock performance. Not at 1080 res.
