2080 Ti overclock instability

[awpshots]

Hi first post and I’m only doing this because I’m desperate because I’m not a fan of forums. Recently my Strix 2080 Ti has been terrible with overclocking!! Used to comfortably have +90mhz core and +1000mhz vram with headroom but now basically every game I try to launch with ANY core oc will crash. However, I’ve bumped the VRAM oc up to +1200mhz and it’s fine. Have tried many things to try to isolate variables but the only problem is core clock oc. 

 

Basic system specs:

8700k @5.1 all core (I think at 1.3v)

Strix 2080 Ti (+0mhz core +1200mhz vram)

32gb Corsair vengeance 2666 xmp 

Corsair CXM750w (Update: swapped to an HX1200i)

 

Full system here: https://pcpartpicker.com/list/Lxvf3b

 

ANY HELP IS APPRECIATED! At first I thought this was a problem with frostbite engine being sensitive to overclocks but this is happening with basically any game I launch now. Can’t find anything conclusive on the internet and after spending $1400 on this card after tax I’m desperate for a solution to get it running at its full potential again.

Have you upped the power limit on the card?

Yes, set to max power & temp limits in afterburner

First suggestion is try to use the OC curve for overclocking and get back to us with results. How are the temperatures in game and clocks? Also whats the model of the Strix? Is it OC or A (advanced)? I am running +165 on core.

[awpshots]

It’s an OC. I run fans at 100% speed because I can’t hear them and I like keeping my card so so it never goes above 65°

Also I can pretty much guarantee a curve won’t change much as literally any amount of core clock offset I’ve tested ends up crashing games

Hmm.. Interesting, as you said that it used to run fine with some OC before.. What about some benchmarks like 3DMark, does OC crash while running that as well? And what are the core clocks when in-game?

Core usually settles in between 1950-1995mhz depending on the game. I can run 3dmark benchmarks with varying levels of core oc and still receive valid results depending on which benchmark it is (I’ll attach a screenshot of my scores) but one thing I do know is that in fire strike ultra/extreme specifically is once I hit the +90mhz (the core oc I used to run comfortably) the screen starts flickering intensely. On time spy and extreme the max core oc I can run was +44 offset, +45 and above would lead to crashes and failed benches. As far as I can remember in my 3dmark stress test runs the only one that would pass with 97%+ were no core oc runs. Side note: with userbenchmark I could stably run core oc

 

edit: these are not updated 3D mark scores I will go grab my new ones

These are my most up to date scores. Was not able to push them further without the card becoming unstable which is disappointing because that happened usually with a small core oc

Remove the overclock on the CPU and there is a chance that your 2080 ti will become stable.

 

That is how it was with my i7 8700k. I could either overclock the CPU or GPU but not both at the same time.

 

At first I thought the FTW3 Ultra I bought was faulty since it only could get up to 77% of the power target at 1440p running Heaven stock along with the overclocking issue.

Fortunately I have 2 gaming rigs with the other using a i7 8086k. The FTW3 Ultra ran perfectly with the i7 8086k. I was so pissed that I ordered another i7 8086k on the spot. The computer has had no issues ever since. 

 

I don't know what was up with my i7 8700k. It was never a good overclocker so I ran it at 4.8ghz on all cores. It had no issues with my GTX 1080, GTX 1080 ti and later 2 1080 tis. All were overclocked. It just did not like the RTX card at all.

Could this possibly be a power constraint? My mobo is definitely not designed for an 8700k @ 5.1 all core (oops) MSI Z390 gaming plus. My psu is the Corsair cx750m and I’m running my gpu off of only one of its cables (with the additional pcie connectors on the cable) could that actually be a possibility for power constraints? Also wanting to eventually upgrade to a 9900k w/ a Maximus 11 formula mb later and a 360 aio for 5.1+ on the 9900k (and presumably a 1000w platinum or gold psu)

It was not an issue with my setup since I use Hero boards and I am running my i7 8086k at 5.1 on it now. My power supply is an 860w and it ran 2 1080 tis with no problem. 

 

It could be you problem though. You might have to through some money at it to fix it. 

 

I have tested an i9 9900k with 5ghz on all cores and it is not a good upgrade for me. One of my i7 8086ks is slightly faster in games and one is slightly slower. If one of my CPUs died it is the only CPU that i would buy since it is the devil I know.

I'm looking at buying it because I love BFV but it's so CPU intensive my 8700k is actually bottlenecking my 2080 Ti in 1440p on it, I also stream on twitch and that's impossible for me on BFV when my 8700k is already maxing out on it. I'm also looking into learning how to actually edit content for YouTube rn instead of just trimming clips and uploading them lmao

but not being able to have a stable OC on both my components seems like a power constraint. for the time being, should I step my OC down to all core 4.7 or do you think it will be necessary to actually get rid of any kind of oc? it would pain me to do that lol

 

side note your mobo is probably gonna have better power delivery than my budget msi z390 board

I'd try running two separate PCIe cables from the power supply to the GPU for a start to see if this is your problem.

Bump TLDR: previously ran fine with overhead at +90mhz core offset and +1000mhz vram offset. Now crashes with any amount of core oc but still remains stable with even further vram oc

 

do I need to RMA or can this be fixed?

I doubt you'll be listened to for a RMA, overclocking isn't guaranteed. If your card runs the advertised boost/memory clocks, it's working as advertised.

is this a recommendation based off the "hey I mean maybe" mindset or is this a genuine problem? I've seen many different perspectives on what seems like a simple concept (a cable providing power)

 

also side note it used to work fine with just the single cable

[awpshots]

I think the biggest thing about this is that it all used to work fine until it just.. didn't

That seems to happen a lot.

I ditched my 1080 ti SLI setup because after the RTX launched my favorite SLI games started to run better with one card disabled. I only noticed it was fixed because I did some tests before installing the RTX card. 

Right now is the first time in years that I have had 2 computers running perfectly(not including RTX heat issues) at the same time and I know that it could change with an update be it Windows, drives or bios.

I'm going to try to dial back the oc on my 8700k to 4.9 all core and add a bit of core oc to my gpu and run some benchmarks and stress tests. I'll come back and bring my results after

 

side note: just 20 minutes or so ago got an Nvidia driver update, seems to be mostly for 2080s launch but who knows, so I'm gonna first try to just add some OC without dialing back my 8700k just in case

[awpshots]

Running time spy with +30 core offset and +1000 vram offset and (so far) it seems to be running like nothing ever happened. Will be trying +45 core offset after because that’s where it was crashing on other benchmarks

[awpshots]

Got up to +60 and everything is working fine, however with CAM software up it’s boosting fairly high initially but then falling down to low to mid 1800s.... don’t know if this is because of time spy specifically but it’s not something I’ve seen happen before

[awpshots]

Running +75 and +1000 right now and it’s boosting high then maintaining low 1900s for a while before dipping to 1890 however over time it is getting down to mid 1800s

I’ve got it stable in the time spy benchmark back up to +90 and +1000, doing a time spy stress test now to see if it’s back to functioning at these offsets. Will update
