Undervolt limit

Recommended Posts

Posted · Original PosterOP

Hello everyone, I have a question that may be kinda stupid. I´m undervolting my 2080 SUPER and I wanted to know where I should stop. Actually I´m in 0.881v which so far is stable (1 hour playing the withcher 3 with no crashes nor artifacts), but this seems like too much. I´m worried that there is something else i´m not taking into account.

 

Thanks in advance.

Undervolting doesn't really have a safe limit, whatever is the lowest you can possibly get without instability/crashing is ideal. Components will only be damaged by too much, not too little power.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

if your worried about it being unstable just try running it in a benchmark in an hour or so, thats the easiest way to tell if its stable or not.

 

i would just go down little by little until the frequency cant keep up.

Thanks for the replies, what concerns me is that maybe the GPU is reducing frecuencies to avoid unstability or something. But according to Aferburner it stills beetween 1905-1935 Mhz. I´ve compared with a friend with another 2080s and he can´t go under 1,012v. I find pretty strange that the difference can be so big.

he may have a different aftermarket card

Make sure to run some benchmarks to compare vs stock to make sure you aren't losing performance.
