Overclock ??!!!

[TIG]

For high-end GPU cards like RTX 2080 Ti or GTX 1080 Ti, do you prefere to use them with or without overclocking by any app like MSI Afterburner, GPU Tweak ... etc

[The Chicagoan]

I prefer to use MSI Afterburner.

I believe it will give unstable GPU performance that would lead to game crash.

I also use MSI Afterburner

play it in gaming mode. you don't have to do no more. The risk is when it spikes to 80-90 celsius it will reduce power. So it ain't much you can clock.

In fact, using MSI Afterburner, I have no temperature issue for my RTX 2080 Ti that never reach to 70 C. Still I believe overclocking makes the GPU performance unreliable sometime

Overclocking the memory clock too high can reduce performance, it's probably to do with error correcting or power delivery. The key is to find the sweet spot. My 2080 runs with a +400htz memory overclock, but +320htz is where it's running its fastest.

Overclocking the GPU clock too high usually just results in a driver crash.

Then don't overclock if that's what you believe. No clue why you were asking if you already knew the answer though.

It is indeed because of a smart power delivery system. To be exact - it's because of power limit.
Pretty much every modern graphics card has got a lot of fail-safes. One of those limits the amount of voltage the graphics card is allowed to draw, and it's within its BIOS. The very same modern graphics card is very likely to use some kind of boost system for its GPU and VRAM clocks. In your perfect example +320MHz on VRAM led to better results than +400MHz because that extra frequency needed more power, but as you put some load and graphics card boosts its clocks - it's very likely reaching its power limit, so the only way you can get extra voltage for VRAM staying withing this very power limit is by lowering the voltage on GPU.

As long as you oc properly, it will be pretty much just as stable as stock.

The biggest issue with 2080ti is the power limit, that and the best cards seem to actually be the founders for high clocks annoyingly (seeing as I have a ftwn3 ultra).

As for memory, there are 2 suppliers, Samsung and micron, Samsung can overclock by alot more, like [phone]MHz while micron seems to hit a wall around 850MHz (runs but unstable at 900 and crashes at 950, though I've read alot of micron stops by 600).

Beyond that, again, just like pascal, Turing is very temperature sensitive.

Right now, I'm using an auto curve oc as it's fairly solid (2040) and not had the time or patience to really push it manually as it's run as an htpc 24/7 so efficency is sort of important to a degree.

Edit.

I've always had better results with afterburner than precision, even on evga cards.

I overclock the GPU when I need the extra framerate from a fast-paced, demanding game. If you have good cooling and properly stability test, you shouldn't have any issues.

Thanks Monk.
For RTX 2080 Ti and MSI Afterburner, Do you recommend to keep memory clock at 0 value?
As per OC Scanner, I use Core Clock +160 MHz.

[Monk]

I'd go 50 below stable max to be honest, it's pretty fast to find that for memory to be honest, run unigine heaven in a window and increase the memory clock 50MHz a time until it crashes, then pull back 50MHz and make sure it completes an entire run at it and your good to go.

This won't win you any oc records, but for 99% of people it's a fast and solid way to get a good oc.

You can star at 500MHz on gddr6, use gpuz t see if you have Samsung or micron memory (it will say half way down the page next to memory gddr6), if you have Samsung, expect around 1000 - 1500, on micron expect 600-900.

Fir a quick and relituvely efficient oc test you can apply the same process to the gpu core, only drop the incmriments to 10MHz.

To get the absolute best performance, you'll want to create a custom curve or go with a fixed clock, but in day to day normal use, you won't really notice much difference, I've got to admit the auto oc features and curve are very impressive this generation, to the point that I'm just using that with custom memory oc.

Edit.
As for the gpu oc, the MHz oc you manage doesn't mean much, it's the total it runs at that matters as every chip varies quite alot, I've read of 2080ti getting 2150MHz but I seem to be stuck around 2070MHz, though, I'll admit I've only spent a few hours tweaking it so far vs the weeks / months on my main rig.

Excellent explanation.
Normally with MSI Afterburner, I reach with my RTX 2080 Ti till 2100MHZ at temprature of 65C as maximum. But yesterday, I got crashes several times when I run Battlefield V and Just Cause 4 both at 4K display and ultra settings. I really get worry now.

[Monk]

No need to worry, just pull the clocks back a bit, also, test memory and gpu oc separately to find stable before testing both.

I'll usually use unigine heaven for basic setup, then 3dmark firestrike to fully test and fine tune.
I'm starting to use timespy and superposition but, honestly, I've used heaven a d firestrike for so long now I k ow e actly when an issue is likely to happen and know what to look out for, still need to learn the newer tests to use them effectively, but if starting new, I'd use the newer ones I guess.

Really, there is no one right way to go, this just happens to work well for me.
