Discussion RTX 2080 Ti Overclock Gains - Thoughts?

[Notorious^]

This is just one benchmark of many to test on but wanted to show my beginning baseline run vs. where i am at so far on tweaks. Benchmark Software i'm working with (right now) is Unigine Heaven 4.0. Still have to test with 3D Mark, Shadow of the tomb Raider built in benchmark and a few others.

First picture is the baseline run at stock CPU clock speed on my i9-9900K and stock GPU settings. Also testing is done at fullscreen @ 2560x1440 resolution on Ultra settings.



Next picture below is on a 5GHz overclock and using the EVGA X1 software to overclock the GPU.
Settings i have modified in the X1 software,
Target Power & GPU Temp = Max
GPU Clock = +175Mhz (Max it seems the card can handle on this Benchmark. Benchmark crashes if i go +180MHz)
Voltage = 100
Memory Clock = +1325MHz (8325MHz)(Still climbing on testing with no crashes)
GPU Fan Speed = 100 Max
Temps AVG 69c-71c (GPU)



I wanted to show these results for the pro overclockers to compare.

very impressive on the mem clock the core clock is about normal for an nvidia card. but will the OC hold while gaming?

What do you get in Time Spy?
I get 16056 game stable 16400 game unstable but my OC is lower than yours as my memory is Micron. From your high memory OC I guess you have Samsung in GPUZ?

Yes i have the Samsung GDDR6 in my card. I have not made it to 3D Mark yet, i am getting ready to run through it now. Going to run a fresh baseline run then dial in the OC results. I will post up my scores when i'm done.

My +175MHz OC on the GPU clock speed didn't fly at all in Shadow of the tomb raider lol. Crashed immediately. Had to back it down to +100MHz to get a run out of it. Also back the memory clock to +1000

I am at +115 +1000, your high core oc is making you crash. Also what I found out is that clocks on RTX start dropping at 40C, my clocks drop from 2130 to 2085 at 40C then to 2055 after 60C.
I have setup an aggressive fan curve so my GPU maxes at 60C.

Welp best i could muster is 15734 in Time Spy
+175 GPU Clock
+1300 Memory Clock (8300MHz)
5GHz CPU

Her's my max game stable OC:

I couldn't upload the image to tomshardware.
I know my CPU is very weak and old. I will replace it with Ryzen 4000 when it comes out.
I think your's is lower because I have a more aggressive fan curve to keep the GPU under 62C.

btw I am on air cooling, I have seen people get 16800 with watercooling.

Yeah im just using the fans on the GPU to cool. I have them set to max rpm - 3700 rpm. My thermals get to about 69c-71c on the GPU during testing. They hang around the 50's for a bit but then shoots up gradually.

You need to run a game with RTX and DLSS, like control or metro exodus.

I don't play those games but I have Port Royal RTX.

Edit: I will post my results when I have time.

I ran port royal thinking it was enough but crashed within minutes of running Control.
