Just got my GTX 1080 ti SC2 Hybrid.
I am trying to find a stable OC.
I have MSI Afterburner + EVGA Precision XOC loaded.
Using MSI Afterburner, I have + 40 on the core.
When I run valley, the MSI + EVGA Core Clock shows around 1956 stable. But the Valley OSD shows a core clock of 2025.
Which one is correct?
If a try and put a + 60 or over I getting crashes

I think what you're seeing is the difference between the boost and the overclock. Also, the card will start throttling as the temps go higher.

Valley doesn't read the core or memory speeds correctly, it hasn't for a long time. PrecisionX or Afterburner will show you the correct readings (and hopefully you do NOT have both running at the same time! That can cause issues like BSODs or game crashes).

+1, don't run both at the same time!

Thanks for everyone's advice.
What is an good not extreme OC for the Memory, in Mhz?
I am currently at 5603Mhz with a + 100 in MSI Afterburner and not sure how much further to push it.
Also my core clock seems only able to hit 1980 :-(
Thanks again for the advice

I use GPU Shark for Monitoring my GPU and I Overclock the GPU only with XOC.
I Overclock the GPU +230 General use +200 for benchmarking and +190 for Gaming.
I do not overclock the GPU Memory.

Every card is different, but the top end for the 1080 Tis GPU seems to be 2074 or so MHz. Most top out around 2000 to 2050 for stability. Of note is that overclocking the VRAM can LOWER your max stable GPU clockspeed. Why? It requires extra power to push the VRAM higher, taking that power away from the GPU core - and with the 1080 Ti, hitting the power limit that Nvidia imposes happens a lot. So if you find that your GPU clockspeeds drop down a lot in certain games, try lowering the VRAM overclock to see if that helps.

Interesting. What core clocks are you getting when gaming with +190? I am only putting a +40 on the Core, using MSI Afterburner and getting Core Clocks around the 1940 to 1960 Mhz. Am I missing something

2088MHz most of the time but on my AMD only 2075MHz Luck of the Dice or Cards, Two Cards are a Pair of Aces and the one Card in my AMD is only a Queen.

What would you say is the in game FPS difference, with a Core clock of 1960 to 2075MHz? Should I be OK with a card that can only get to 1960/80MHz I know its a luck thing, but are most of 1080 ti users hitting 2000Mhz+

The difference isn't significant enough to worry about. We are talking 1 to 4% actual, real world difference.

I would get crashes often too when overclocking, but after some driver updates(nvidia) and the current msi afterburner ive been running stable. The hybrid cooler is amazing, my temps never go above 50. Heres my overclock settings in afterburner and temps.

Well done mate! You really lucked out on the Silicon lottery there! I don't know about the AMD card enough to comment, but "2088MHz most of the time." Is really top 5%, or better! My FTW3 (which I like a lot) can accept a simple +40MHz on core, but stability I use 1bin lower, so +26MHz basic offset. Voltage set to half way up the XOC slider, power 120% (slave bios), temp 88c set, and memory +400MHz. Luckily this 400MHz+ on vram doesn't lower the core as far as I can tell from benches etc, and many hours gaming. I won't put it higher though although it can go over 500MHz + easily. Important bit. While gaming and benching there are variances but my core runs at 2025MHz and 2012MHz most of the time. It's highest spike is 2038MHz. Stable. But your average is over 50MHz better than mine. I consider my GPU core to be average, but I'm happy with that. 2,088Mhz running - just wow!
