RTX 3070 - overclock parameters and results.

[Michal_UK]

Hello - I do apologies for my basic questions as I just started and try to find  best solution for my RTX 3070 graphic card mining.

I've got 2 ZotacGaming Geforce RTX 3070 (one black and one white edition).
I'm using NiceHash with Windows 10Pro, my example on DaggerHashimoto Phoenix.
I searched and found a lot of different overclock parameter setups.
Unfortunately on one of the card very often I've got the message  "Incorrect ETH share from GPU0" and sometimes "Share rejected in  ms".
My current setup which generate the lowest amount of troubles is:
 
Power Limit 70, Core Clock 0, Memory Clock 1200 (screen shots below shows readings this setup).

I tried Red Panda suggestion and other guys from youtube - for example:
Power Limit 52, Core Clock -200, Memory Clock 1200 and 1300
and more more others.
But there is more or less the same story.

What are yours setups and what else (apart from MH/s) should I tune/monitor to get stable mining

can get lower watt , speed is ok . 2 fans model doesn't have good cooling so can't go 63-65

Thanks for this  hellscreamer. I'm approx. 155W on both - how much down do you suggest?

try:
Power Limit 55
Core Clock +50,
Memory Clock + 1200-1300
I saw tests where Windows and Linux were compared, and on Linux it turned out to be 10 watts less consumption.

Thank you for this FP91G - I just applied - looks ok - I'll give him couple hours.

Limit power by using voltage - reduce it until the memory drops to 5000mhz, then bump it back up
My 3070s are doing 750mV, -500 core +1450 mem for 63.5MH/s @ 135W atw

If you lower PL to 55% rather than lowering voltage, you'll get same conso no ?
I did this with my 3060ti, and I get 63mhs@131W with PL 55%, core -502, mem +1400

By using voltage, you get the lowest PL limit before throttling. You would be able to achieve this using PL, however you'd have to change the value bit by bit to get to the same point. Also, different cards will require different PL limit.

two questions. everywhere i read I see coreclock -200 or -300 (what does this do besides lowering power usage by few Watts?)
and how safe for card is overclock above 1000 for memory? as i read somewhere max safe adviced is 1000.

I have seen this on some of my rigs too. But only at nicehash.


Setup your worker at 2Miners Pool for a test.

When your rejected shares are gone - its all ok.
If not, lower the RAM Speed.

mem +1400 very high memory overclocking
What do you think is better than 60 megahash and 120 watts of consumption or 63 megahash and 130 watts of consumption?
Everyone chooses the optimal ratio himself, but maximum acceleration is not always the best.

The card is the trioX version, extremely well cooled, core is 45 degrees max.
I know mem could be a lot hotter, but compared to 3080 / 3090 GDDR6X who thermal throttle a lot, I don't suffer of this issues at all with my 3060ti's

And lowering the mem to +1000 instead does not lower the power consumption at all. Still 130W
