Post your hashing efficiency!

[Deleted member 50521]

I will start with mine

single rtx3090, efficiency is about 411k/watt. Hashing with NBMiner using DaggerHashimoto running at 105MH/s

Power consumption is limited at 255Watt. Fairly low temp and fan noise. I am doing -400 core and +300 vram

GPU hotspot is about 10C warmer than GPU temp. GDDR6X junction temp is about 90C max. This is with me having ~50 browser tabs open and running some CPU jobs through wsl2. It really does not add a whole lot of stress to the system. Overall responsiveness of system also feels great.

Now let's see yours~

Well, that's an interesting topic. I've been doing some maintenance for customers, and started to keep an eye on that number just in case.
Basically with all the hardware that I've tested:
1) RTX2060@130W with my current settings of -400 core +750mem gets me around 320kH/W. The most I could get is around 350kH/W with 75% power limit, but it was less stable since I use this card in my main PC(hashrates fall drastically even when watching youtube or just browsing).
2) GTX1070 in my server runs in a 280kH/W region, but it can get as high as 300 on minimal power limit if I sacrifice some effective hashrate. ATM running +100core +600mem at 80%PL, and temps never go past 55C at 50% fan speed (it's a beefy EVGA GTX1070 SC ACX3.0, which previous owner for some reason never-ever cleaned). It was expensive, but still... I paid $350 for it when the market average was(and still is) upwards of $450.
3) P104-100 is probably the best of the bunch, considering how old it is. With 50%PL you can tweak it to run on-par with Turing in terms of efficiency!
That was a client rig, which was initially built by a stupid dumbass. I've replaced the PSU with a properly rewired Emerson 80+ Platinum unit, got rid of all the power adapters, dongles, lose wires and other random firehazard, re-tweaked the 6-card farm to run as efficiently as possible, and got around 300kH/W with 70% power limit (or as high as 320kH/W on 50% power limit). Running -100core +500mem, 50% fan speed.

I've only started playing around with mining during this boom, mostly because this time I have my own apt. with a shitton of computers (soon to be expanded with a proper 24U rack and a couple servers).

I find disabling browser's hardware acceleration will offload the GPU to CPU. For any system with >6 core that should not be a problem like at all

That's fine. Just bumping the PL up a little makes it almost unnoticeable. I think even a fullscreen 4K stream doesn't hinder the hashrate below 39.
Few days ago I've also tried a little experiment with decoding. Had around 100GB of some videos from a co-worker that needed some re-encoding. Just some old trips in 480p. Normally I'd get around 500-ish FPS in handbrake using x264(NVEnc), but with a card at lower PL I managed to get around 400-450FPS, all while maintaining decent hashrates above 30.
This leaves my brand-spanking new CPU totally free to do its own stuff, like compressing a 300GB worklog backup from server!

Had my rig running at whopping 160MH/s with 5x RX580 for many hours but one or two GPUs kept producing incorrect shares thus the 0:20 running time as I'm still calibrating it. I'm talking about having 1 incorrect share to 100 correct shares so it's almost nothing but as I'm autistic, I am still tuning the cards a bit down to have my sweet spot of 0 incorrect shares.

Here are my current stats:

Something interesting happened today. Not sure whether it's due to Excavator updates or new Nicehash power profiles, but I went to sleep last night(or more accurately, this morning), and my efficiency was still casually sitting at 330-340. Woke up, and all of a sudden that number became ~370kH/W. Hashrates are the same, but the power consumption went down by ~10%. Haven't changed any settings, haven't tweaked any software.
