What markers do I use for a successful GPU OC (Laptop)?

[marsfarce]

Hey guys,

 

I've been patiently messing around the core and memory clock overclocking but I'm starting to realize I don't really know my reasoning behind, say, 100MHz vs 150Mhz on the core, for example.

 

My question is what sensors/markers do I use to see if my overclock is successful? I'll explain with some details below.

 

The voltage on my 2060 laptop GPU is a constant 80w so I can't mess with it. I am currently monitoring max GPU temperature, average core clock speed and Heaven Benchmark scores during a games like Overwatch (uncapped FPS) and Metro Exodus. 

 

The difference for example between a 120Mhz core OC vs 155Mhz core OC is minimal on the heaven benchmark, and I don't see a difference in average core clock speed during overwatch, nor do I see an increase an average FPS during the game either, while there is an increase in GPU temp by 2-3 degrees. Does this mean that 120MHz core OC is a desirable place to stop OCing?

 

Also, HWINFO64 says "Performance Limit - Power - YES", while "Performance Limit - Thermal NO". Does this mean the GPU excess clock demands too additional power that the 80w can't meet and therefore any further OCing of the core clock is useless?

 

Any help would be appreciated. I'm really eager to learn all these metrics.

 

Thanks

what about a middle number, say 135MHz offset?

 

It just means it's power throttling, not thermal throttling. However it cant detect clock drops caused by GPU boost 4 backing off due to thermals

How about Afterburner ?

I'm sorry is didn't quite get you. Gpu downclocks to avoid overheating, I get that. Who can't detect the clock drops? Hwinfo64?

What about afterburner? I use it to oc manually. The oc scanner gives me bsod.

oHH ok

None can detect the clock drop. GPU boost is the name of Nvidia's boosting algorithm, aimed to maximize performance by scaling frequency automatically based on their tests on how their silicon lose stability as temperature increases. It runs outside of factory base and boost clocks by default, so it doesnt count as thermal throttling.

 

Nvidia's thermal throttling tends to hit like slamming on the ground by suddenly locking to base clock, so if you're getting smooth frequency changes it's not thermal throttling.

Ah right, so this is definitely not happening with me at the moment. 

 

Interestingly it says performance limit -power-yes on stock clock settings after so this doesn't seem to be an indication to stop oc'ing I guess. 

 

Since I didn't get any throttling at 155mhz and my temps were around 70-72, I guess I can crank it up a bit more? 

 

Are the gpu temps the main factors that you guys look at during an oc really?

DO NOT overclock laptop GPUs.

See I'm a beginner overclocking in general, but I've read sufficiently to see that the RTX series are totally overclockable if you've got the temperature head room. In fact, the Acer Helious 300 comes with the GPU overclocked out the box. There's been tons of people OCing their 2060s, 2070 max-q's,

Sure, and yes

Any proper reason? Temperature is monitored, power and voltage are both locked, if it still shouldnt be done then the same can be said for desktop cards.
