Hey all, just finished my new rig and looking to get a modest 24/7 OC setup (to start with). Last GPU i OC'd was the original Nvidia Titan so it's been a while, want to get some suggestions before I push it too much. My Rig is a 2080Ti FTW3 /w Hydro Copper block & 9900K
 
So far i've got +100 Mhz core, +500 Memory and maxed out the power limit. I've not adjusted the voltage at all yet. I've also run the scanner thingy and it's given me a score of 103.
 
My main questions are, do I need to fiddle with the voltage or will it be limited by it's power envelope before needing that and what rough figures would you aim towards for a 24/7 OC? Appreciate the  exact figures will depend on my cards silicon lottery.
 

Especially on a waterblock slam that voltage to max, it'll pull the core up a bit higher.
Also you likely have a bit of room on your memory. Most of these cards from what I've seen are stable at +1000 or more

Thanks all, so general consensus then is to try out +1000 on memory and up the vcore voltage? Is there any issues with me maxing the voltage out or is that fairly standard as with previous gen chips?

I ramped up by 150mhz at a time from 500 just to be safe, I have had no issues at +1000, probably gonna begin increasing by 50 until I reach my max. I'd say err on the side of caution and start at like 750, run superposition for a bit, go up and repeat till it crashes.
And yea, you cannot reach an unsafe voltage it's a little more locked down then previous gens. I run 2100-2130 constant on air, with max power target and voltage and +1000 memory and the card has never seen 70c
So id definitely say maxing it out is safe

Ok cheers, will give it ago later. I did suspect that maybe the case with the voltage from reading various articles about it but thought best to check. I take it the vcore voltage has no bearing on what memory clocks you can reach? If so ill leave my 100mhz core clock with stock voltages and focus on memory until i've got a solid OC on that, then push the core further. 
 
I know previously on my titans at least there were separate vcore and mem voltages, but not sure if they have just removed the option for memory or if it's in someway linked to the core voltage.

While trying to find the edge of what is the best stable OC your Rig will do, change your GPU OC software - so it does not automatically load the last OC settings on reboot.  Those are not the reboot setting you want right after the unstable OC crashed your Rig 
 
After you get your CPU & RAM locked down with stable settings - then see what your 2080 Ti FTW3 can do
Find your best GPU setting, back off those numbers by 10% for daily stability
Now go find the best RAM, back off those numbers by 10% for daily stability
 
Remember Nvidia Boost 4.0 has the last word.  This locked firmware is really in control of your cards clocks & watts. 

You need to try and encourage your card to its limit.  Unlike in the past where brute force could push the GPU, you are allowing your GPU to reach its max ability - before Boost 4.0 pulls it back from a theoretical edge.

I think you have received good advice.
 
Two thing's Id like to add.
 
The OC scanner has been very reliable for me when I have used it for the 4 RTX GPu's I have used it with. Id max out the voltage and power slider's all the way to max so the scanner can give you the best possible core clock. Leave memory at 0 for now and run the OC scanner to get a core reading.
 
After this run superposition with the updated core and write down the score.
 
Then put in around + 500 in the memory and run superposition again...compare the score... it should be higher...if not it's because the memory has "error correction's" if its not stable...the superposition may actually complete and not crash but the score will be lower if error correction took place...I usually start with + 500 and move up +100 or -100 depending on the next score result's until my score get's lower then decrease the memory by -100 and verify the result and if good I leave it here...with my main card it made it all the way to + 1500 (maximum allowed in MSi Afterburner) but the overall score was much lower so I knew the memory error correction took place and was not stable so the I backed up to +1400 and the score went way up (I used 3dmark Firestrike for testing).
 
Good luck to you.

One thing that was not mentioned on the GPU overclocking (someone correct me if this is not true for the 20** series cards like it was for the 10** series) - when doing your steps do it in sets of 13 = 13 -> 26 -> 39 ect for both the GPU core and memory

Game On

Did some testing last night and running fine at 110+ core and 1000+ memory and didn't break 50 C under load. Will leave it there for a bit and see how things go, thanks all!

 
what are temps on memory and etc??
 
Thinking about getting this or waiting for waterblock to come back in stock and attempt to build my own loop. 

 
Below are my temps during a run of extreme Superposition @ QHD Res - Very happy with the blocks ability to cool the whole card, the memory, core and VRMs are no issue at all! 
 
If it helps, i was waiting for the Hydro Copper block to come available on the EU site since December 1st (live in the UK). In the end, i just ordered it from the EVGA Ebay store which ships globally, ended up being only slightly more money and took just under two weeks to arrive. Just an option if you get impaitent like me!
 

I've currently 1000+ mem and 100+ core on the 2080 Ti ftw3 ultra, voltage to max, currently no hydro copper because they're not available right now in europe. Temps are ok for air, around 80 °C. Anyway, if I go higher then +100, timespy etc is crashing. I really hoped I could get more out of it. How come that some people can get around 2145 mhz with their evga 2080 ti?

Silicon Lottery... Your temps seem really high to me. are you sure your not looking at the VRMs?
