Re: Team Black Miner!(Ethereum, Ethereum classic, Vertcoin, Zilliqa + dual 0.5% fee)
Definitely gets more speed, around 135MH/s on this 3090. But, poolside rejects go up to around 5%, vs ~128.5MH/s with uner 1% rejects at xintensity 32. If I understand flexpool properly, it only pays rejects up to 1%, so until I switch pools I gotta keep it below 1%. Pretty fond of flexpool though, it's usually one of the better earning pools. Need to run the math on the increased speed with rejects at a pool that pays for stales, but I assume the extra speed would come out on top.

I am using 11.4 and 472.12 is the latest nVidia driver release.
Running that command returns N/A, yes.
Perhaps there's another function you could be using to pull VRAM temps? Temperatures show up fine in T-Rex and HWInfo64.

One more thing I just noticed, under HASHRATE/W field, the unit is kH/s instead of kH/w.
Looking forward to trying this on more rigs with hiveos.

Working well. Miner reported hashrate = 401.6MH/s vs 396.4MH/s for trex.
Possibility of adding GPU hotspot and VRAM temps in a future release?

Congrats on the release. I don't see the ansicolor.reg file in either the 11.2 or 11.4 windows release, though?
Also:
Perhaps consider including the .dll? I know I personally can't be assed dll hunting in 2021.

wow, thats a sweet rig. sweeeeeeeeeeeeeeeeeeeeeeeeeet rig. Well done. Do you manage to pull out more than it costs in electricity ? I'm guessing yes. is it X11 or x13 that uses like 40 watts a card ?
Thanks.
I used to have about 60 7970s back in the scrypt glory days (late 2012 to mid 2013ish), needless to say that they are all paid off many times over. I've sold off about half of them, and now use the rest (29 gpus) to solo mine ethereum. It's worth it for me since I have cheap (~6c usd) power and already had all the required hardware. They were all sitting in a drawer waiting to be sold until ethereum came around. I wish they were consuming only 40 watts! Each card is burning 200 watts.
Gotta say I had fun setting up my gpus again. ASIC are so boring! No skills required.
Figured I'd also chime in with a GPU pic for the hell of it. This is the majority of my ETH mining setup. I have another 9 GPUs mining not pictured here.
Top rig is 7 cards on 1 motherboard, middle is 6 cards on 1 motherboard, and bottom is 7 cards on 1 motherboard. Each rig is running Win 8.1 64bit, with 1 Seasonic 750w ATX PSU per motherboard which powers all PC components + 2 GPUs per rig. The rest of the cards are all running off of 2 2000w server PSUs, and fed 240v through a 30A PDU which is mounted to the rack. That means I only have 1 10AWG cable and 1 ethernet cable connected to the setup, allowing it to be moved around easily when needed.
Sorry for the potato quality picture. If there's any interest, I'll go take a picture of it with a proper camera.
Edit: Ohhhh, look at me! Looks like I'm legendary now! *cracks a Heineken*

this last pic is SO WRONG ...it is so mesmerizing thou...it just wants to suck me in....(must resist argh....) it is a CHAOS TALISMAN
of some type....LOOK AWAY.....(it burns my eyes....)
A chaos talisman, I love it, lol! I though the same thing when I saw that pict, it's like a little ball of wires that somehow mines. GOT WIRES?
I dig the "thing" to power the 3 S7s, but shouldn't you cover up that copper bus bar to prevent accidental electrocution? Looks terrifying! I hope you don't have a cat...
Nah, 12v is too low to get even a shock from, much less getting electrocuted. I think you start feeling electricity somewhere around 50v or so. This is assuming dry skin, of course. Wet skin would be lower. The only danger would be if something made of metal were to short the 2 bus bars out.
Might not be very safe wiring the outputs of two power suppiles together. Diodes might be in order.
They're made for it, so long as the load sharing pins are connected together allowing them to communicate with each other.
Hmm, that's interesting. I have some of these left over from a Terraminer. Sounds like you can basically make a "2200w" power supply out of them.
Actually, you can make an 8800w psu out of them.
up to 8 can work together in load sharing mode. this last pic is SO WRONG ...it is so mesmerizing thou...it just wants to suck me in....(must resist argh....) it is a CHAOS TALISMAN

For the most part you are correct. Just do not wear rings when working with this. Seen several people have cooked fingers from letting rings hit bus bars back in my DC datacenter days.
Ha! Never thought of that. Probably since I don't wear rings, so I'm safe.
So, I made another thing yesterday:
The 2 PSUs are PFE1100 units, pulled from an old cointerra IV box. Thy are really incredible little PSUs, 94% efficency at 100% load. Blows the socks off of every other PSU I have. Up to 8 of them can be linked together if needed, providing a whopping 8800W of pure efficiency.
You may have noticed the the light gauge black and white twisted wires connecting to the 4th cube. Each pair goes back to a breakout board on each PSU. Their purpose is voltage sensing at the load, and allow the PSUs to dynamically adjust their voltage level to compensate for voltage drop across the wires.
The 5 cube Titan (420MH/s scrypt, 1 dead die) makes for a prefect house heater. It's very quiet, which is a requirement with my better half. She didn't even realize they were in the house until she saw them! Temps have been warmer than usual, and these guys have been enough to keep all the heating in the house off so far. When it gets cold enough (below -5c constantly I guess) I'll bring in reinforcements in the form of a 6 cube Neptune.

Figured I'd post this here for people who don't follow the S7 thread.
Decided to "make a thing" to power my S7s . Hope some of you will appreciate this!
2X 2000w server PSUs sharing the load of the 3 S7s. Will shortly be replacing the PSUs with the 2500w versions since I'm actually pulling 4400w DC from them right now, which is 200w over their rating on each.
I've adjusted the voltage output to 12.6v on the PSUs.

Prelude I really like what you did there.
When I use my 2000BBs stacked together I strap the fans using tiewraps and then my cables run straight off the GekkoScience break out boards to the miners, but I like your implementation of the separate connection bars.
Once cable is only 12v, but you are gonna get a nice little bump if you short that to ground with a sweaty hand my man. At least run some silicon, or actually, you could put a small piece of cheap plexiglass across the top of the bus bars. Terminal strips that long aren't that expensive either, but I know if I'd built it I'd be happy and proud of not needing other materials. You probably had everything laying around
Still though, some terminal strips with side guards would be a big bonus.
It is a good looking setup though for 4k watts. I have half a dozen in the closet I need to make a project with.
At the moment everything is running using the 2880s w/ Jabbers boards from Finsky.
Sidehack and Finsky have both treated me well. I've never had a bad experience with either of them with transactions, or with Jabber or Gekko's equipment. I do like the options on the GekkoScience b/o board for the 2000bb as well.
I think I am going to do what you did. I copy good ideas all the time and try to improve them.

I'm really not worried about the bus bars. I've got 2 DPS2500s coming in today, turning the setup into a 5000W beast instead fo 4000W. Once they're installed, I'll be putting everything up on a shelf out of reach. If it was somewhere where kids or pets could get at it, I'd definitely cover them up somehow, but as it is they're in a garage where only I have access.
They're definitely a pleasure to deal with, and both have great hardware to offer. I have a slight preference for sidehack's boards because they have a lot more options available on them, for example the load sharing, 5v for controllers, and fan headers with speed control.
Make sure you send me some pics of your setup if you make one too!
Quote from: klondike_bar
what's the purpose of the busbar, and not just connecting the PCIe wires directly to your breakout boards?
obviously the load-sharing provides slightly better stability/overhead, but for ~$20 of extra materials and at least an hour of added assembly adding another PSU seems simpler
I needed the bus bars to use load sharing properly, need a common bus between both PSUs to pull juice from them equally. I went with this setup because the loading wouldn't have been equal across both PSUs while powering 3 S7s. One PSU would've powered 5 blades while the other only 4. That would cause one PSU to be overloaded while the other one was under utilized. I guess if I had the 2500BB to start with, I wouldn't have bothered, but it was a nice little project that I enjoyed putting together. I learned from it, and the next one will be more efficient.
