GTA 5 Doesn't like my overclock

[sumikrast]

My rig:
4670k @4.2ghz
Gtx 980 ti
Samsung SSD
8gb RAM

Hi, I have an odd problem I am hoping someone can shed some light on.
GTA 5 freaks out since changing my GPU config from 2x GTX 770's to a single GTX 980 ti.
Now when loading and while in the game, GTA will max the CPU at 100%, and as a result, the game is unplayable and will often crash. Starting the game in safe mode won't work after it crashes.
If I return my CPU to stock clocks, it's fine.
I ran a 4.4ghz overclock with my old SLI config and GTA was fine.

Other games work as normal since the upgrade, it's just GTA at the moment.

Things I have tried: update bios, virus and malware scans, and returning to stock clock speed. Ideally I would like to keep my overclock while running GTA 5.

Any ideas? At this stage I am thinking it's just GTA 5's problem, it ran an update before I could test it with the new 980, maybe the latest patch was a dodgy one?

Anyway, appreciate any insight, cheers.

Well did you do a clean install of the drivers? The old drivers could be interfering. And I don't mean with the nVidia installer I mean uninstalling all nVidia drivers with DDU then installing the latest ones?

I have a i5 4670K at 4GHz and even when I had it stock I could max out GTA V without an issue with my 980Ti.

While it could be an overclock issue it is rarely that.

Your overclock probably isn't 100% stable, and you didn't notice until you stressed it heavily. It is possible cpu wasn't as stressed due to a GPU bottleneck on the SLI config, or some sort of voltage/settings change to the cpu since.

Did you stress test your CPU originally when you had the dual 770's to check if it was a stable overclock? maybe with superpi or something?

EDIT:
Your overclock changed, so almost certainly stability issue where new OC something wasn't changed that you did before to increase stability such as voltage change.

I'm not sure if people are reading where you say If I return my CPU to stock clocks, it's fine.

If you go to C:\Users\<your-username>\Documents\Rockstar Games\GTA V and open settings.xml (any webbrowser should work), what does it say at the bottom? Should say 980 Ti.

He also stated that the same overclock on the old SLI setup was fine and if it was an unstable overclock he would have hit a BSoD or crash especially if the CPU is getting maxed out.

If the old drivers are in there causing it to freak out it could cause his issue which is what I would check first.

it isn't the same overclock, his old one was 4.4Ghz and his new one is 4.2Ghz, proving he changed settings and may have forgotten something. if the drivers were the problem then there is no reason it'd work fine on stock clock speeds right? Maybe I am crazy though.

Unless of course he didn't test it on stock speeds long enough, then I'd agree with the driver theory.

He should probably stress test his overclock and stabilize it first, then once cpu is burned in start playing games with it.

Forgot to mention I had done a clean install of drivers, however, only with the nVidia installer, not DDU. Other games run fine so I assume if it were a driver issue, it'd carry over to other games, but this isn't the case.

I think I did prime95 for the original 4.4 overclock. However, not hardcore for 24 hours as some suggest. I took evidence from real world gaming, which always ran great for many games.

OC settings changed only after I noticed problems with GTA. So when the 980ti was first installed, the OC was still at 4.4.

Anyhow I will do some stress testing and reinstall drivers to see what comes up. Thanks for the suggestions.

Yes it does list my 980 ti

Not always as drivers these days have profiles for games and if the profile for GTA V is messed up then it will bug out while other games might not.

It is hard to say that an Overclock suddenly is not happy in a game. There are very few games that have that issue. One used to be VALVe Source engine that hated overclocked CPUs but I have never seen any other game engine hate it that much or have issues.

Make sure to use a Prime95 version older than 26.6 as anything newer on Haswell CPUs uses AVX which will make the CPU run super hot.
