JackCY The only real difference between cards is: chip bin ("A" I think are the higher/better bin used in NV's cards and sold at premium to 3rd parties, they may clock higher), VRAM supplier (Micron vs Samsung), VRM power capacity and quality (ripple, stability, ...).
Most 1000, 2000 series cards will clock to around 2000MHz but out of the box they may only boost to 1800-1900MHz with reference clocks, a +100MHz with 3rd party OC clocks.
Maybe nowadays only A chip bin are allowed OC clocks from 3rd parties as well, you know... Nvidia controlling everything really.

Kaltenbrunner Ok thanks, I downloaded zotac's OC program too, try that 1st. I don't need anymore of an OC or anything, I'm just curious if I can have it match the "better card". And I'll let the card decide the voltage, it's too expensive to worry about LOL.

I'm not taking mine apart, and I only found detailed PCB pictures of the amp extreme

JackCY 2D clock, often some low clock
3D clock, base, boost (more like turbo really but GPUz calls it boost), and boost 3.0 dynamic clock determined by Nvidia based on various inputs: temperature, power consumption, load, voltage, ...
compute clock, usually same or similar to 3D clock

2D clock
3D clock
compute clock, often lower than 3D clock for stability reasons

Overall you're left at marcy of Nvidia with their Boost 2.0 and 3.0 cards. You can apply an offset but the card itself will decide how far it will go and you cannot set a locked clock really at least not without a custom firmware and all.

Renegade5399 In the latest afterburner, I suggest running the OC scanner first. You can adjust the clock/voltage curve from there. The initial scan gets you a baseline of your specific cards voltage requirements.

How does OCing work on RTX cards?

So there's the stock clock, then there's a factory OC like on mine, and there's also the boost or whatever raises the clock even more than the OC. And then there's the power limits and thermal limits. So that right, is there more on these ?

On mine stock is 1410MHz, I don't know if my card ever runs at that tho. The factory OC on my zotac "AMP Extreme Core" is 1815MHz. Yesterday I saw 1925MHz held while I played FC4.

In up-to-date Afterburner, it only shows offset clock speeds for some reason, so I set the power limit to 110%, with voltage control off, and in game it still only ran at 1925MHz. I haven't tried manual OC. And IDR what the vram has been doing. IDK anything about the BIOS of GPUs in general, I hope this is not a card thats really strict and only allows what the factory set. I bet there's next to no difference between my "AMP Extreme Core" card at 1815MHz and the top zotac "AMP Extreme" at 1860MHz.

Hey I'm real happy with this card tho, with out of the box fan profile and everything else, its never gone over 68C, and its very quiet compared to all my past cards. And THERE"S NO COIL WHINE. I had a touch of that on my 980 ti
