Hope that helps.

Nice! Thanks for that! smile.gif

2063 core, 6009Mhz memory Heaven run. thumb.gif Thanks for advice!

Yeah, I keep saying this. Boost 3.0 took the fun out of OC, but at the same time it got us close to the limit of these cards with hardly even having to do anything.



So before you get the urge to shop and return a card, just know that Boost 3.0 is taking good care of you.

And look at the average overclock for air cards

http://hwbot.org/hardware/videocard/geforce_gtx_1080_ti/

1830 on air and 2045 on water.

So don't feel insecure about your cards unless you're lower than the average.

So i took the time to read through this thread. I originally was thinking i left some power on the table but now it seems like I got lucky?

Took about 10 minutes of tweaking and maybe 2 hours of testing to hit my 2100mhz gpu/6000mhz ram on water.

That being the case, would flashing a bios like the SC2 possibly get me even better results?

for pushing over 2100mhz gpu would crash games/benchmarks instantly. pushing past 6000mhz ram caused major artifacting and eventual full system crash.

edit: oh and i've been using Precision X OC. Is there a benefit to using MSI Afterburner?

That rainbow is weird. i only got it a few times. try a baby voltage bump and lock it one higher up the curve and see if it goes away or at least goes to just blue.

What is a "baby voltage bump and lock it one higher up the curve mean"?
Does this mean if I am currently having (1.012v @ 2037) and flatline above (1.012v) then I should move to a lower clock like 1999 @ 1.012v and have the next voltage (1.025v @ 2037) so like try moving my curve up one voltage step?

It is tedious as Slackaveli rightly noted, but its the same principle as overclocking a CPU, pick a voltage a see what the max clock is, the raise the voltage a step and see how much more you can get. 1.000v stable is likely a good point for all cards not to get green in most benchmarks. Tests like SuPo 4K are designed to ruin your day smile.gif, but games will be fine.
My gaming curve is default FE curve, with 1.050 raised to 2101 and flat after and its fine because the games I have been playing barely reach 120% if ever.

Should I when testing make the curve flat line on anything above the voltage I'm testing? So like 1.000v and above flatline test.
Once I find max stable I go to (1.012v) and flatline everything above (1.012v) to find the highest stable clock? etc. etc.?

I'm kind of repeating questions but I want to make sure that I'm correctly understanding.

Also, If I don't have a 4K monitor (only 1080p) can I still run the 4k tests with SuPo and other benches? I'm assuming the answer would be NO that it doesn't somehow virtually apply a 4k resolution in like a sandbox environment.

ps. That Rainbow happens to me a lot.

What is locking / unlocking the curve and how do you "lock" the curve?

See the video.

I wouldn't say it was luck, but all that hard work putting it on water. On water you're getting about 80 extra mhz than someone on air.

The SC2 bios may or may not help. It helped me. Witcher 3 crashed a few times 2114 Mhz at 1.062v, had to bump it to 1.093v.

Now I'm 2114 Mhz at 1.062-1.075v and can run Witcher 3 all day with it with SC2 bios.

what kind of risks are involved with a bios flash? I'm not really willing to do the shunt mod and risk a $700 brick, but bios flashes seem simple enough.

Nearly no risk. If anything happens, you can just connect to your intel mobo integrated GPU and reflash it again to fix anything.

But I've reflashed and went back and forth at least 40 times now with no issues.

But I'm not sure what will happen to you since you are on water and don't have the fan plugged into the controller anymore. I think EVGA might have the card crash purposely if it doesn't detect a fan. Kedarwolf never got back to me.

But it's worth a try. You might get more OC. I actually gained +100 on my memory.

Very pleased with my STRIX so far. 2063 and 6009mhz Memory stable in BF1 all the time. 130-142 fps in game. But really I will have to push up Resolution Scale it seems as its hard to put that card to 99% usage biggrin.gif.

This is my second 1080 TI STRIX (first one I returned). And so far seems like STRIX card have nice chips, or I was lucky enough.
