My 3070ti is doing 80.68MH in hiveos, you need to find the right OC for your card, mine works stable at 2600Mhz Memory clock while someone I knew very well can't get his 3070ti to 2400Mhz without crashes.
Many miners use different memory settings for video cards from the same batch. If you are lucky, then one or two video cards out of 10 will mine 76-77 megahash, but the main thing is that the memory does not overheat. Not all of these video cards work stably at a frequency of 2600 Mhzi found in my country PNY GEFORCE RTX 3080 - 12GB price drop to around 750usd this card is good for mining or pick other brand is better?
Most of the RTX 3080 video cards have memory heating and hashrate drops. This is solved by replacing thermal pads with thermal paste or buying a good closed case. I would not advise you to buy this video card first for mining, if you are not an experienced miner.
There is another solution, but a lot of miners don't see this or don't want to pay extra. Gpu models with better coolers are a bit more pricier because not just the coolers but also the higher clocks.
For example i have 3080ti suprim x and gaming pro, temps are not even close.
3080ti palit gaming pro width is smaller (1 inch) than zotac 1080ti amp extreme, the weight i didn't measure but 3080ti is even lighter
That 1080ti is even cooler at 300w than that 3080ti at 300w.
Watts is watts = heat.
My standard for coolers for gpus that can pull 300w is like that of zotac 1080ti amp extreme, the msi suprim x exceeded those, they are better.
Yeah, thermal pads are problems but even if they can transmit the heat a 100% (no loss), you will be limited by the heat sink(metal quantity and airflow design). Even if you use the best of the best thermal pads and the heat sink is just 100grams of metal, you are not going to cool those cards whatever you do....maybe by putting them infront of an AC will do lol.
Here is an example: 290/290x, when they are released the coolers are not enough, then same chip (refresh) 390, bigger cards, bigger coolers then the true potential of 290/290x are realized.
But if we are talking about heatsinks for the 3080ti/3080, then these models have high-quality cooling, and when replacing thermal pads, the problem with the hashrate drop ends.
Not all have high quality cooling, palit 3080ti gaming pro is one. Just pointed it out that there are 1080tis that have better coolers(bigger) than some 3080ti, they are all good enough but in mining where you are reaching the temp limit of your mining area, you may have the chance to add 3-5 more gpus compared cheaper coolers (the room might get a bit hotter but the cards can handle it).
I just observed, didn't look at the datasheets but 1080ti core is hot vram(gddr5x) is not as hot as gddr6x, now 3080ti, core is hot plus the vrams(gddr6x are hotter than gddr5x), imagine that 3080ti has a smaller cooler than the 1080ti.
The 3080ti suprim x has exceeded the size of that 1080ti..suprim x is a superb cooler.
