I've never seen one reaching 130MH lol, I have friends who build a 3090 GPU with 6 of them and their mining hashrate is from 110-120M max, though with GPU mining silicon lottery is always a possibility but they are rare with 3090s and if your friends 3090 is delivering that 130MH for real then it's silicon lottery, don't go out to buy same GPU because you will be disappointed
And if he is not cooling that ram while using 330 watts he will fry it.
i use 280 watts and get 113 I bet my gear lasts a lot longer than his will.
Lol that's true, 130MH on 3090 can ruin the GPU if it's overclocked, fair hashrate can prolong the life of GPUs I don't see any reason to OC them which put strains on them and shorten their lives, in fact I prefer 3070s over 3080 and 3090
Probably the author of the topic thinks that the memory of the Samsung is not heated, but this is not true.
Ethash algorithm is highly dependent on the memory frequency of the video card.
The best solution is used in the top versions of the Nvidia CMP series, which uses HBM2e memory with a 4096-bit interface.
