Recommendations mining ETH with 4 GPU's in a powerful rig?

[cryptocrypto995631]

Hey all, new to mining.  I have a rig which is a 4U chassis with great cooling (basically the whole chassis front to back has ventilation and powerful fans running through it, 96GB RAM, Xeon Gold CPU, 4 PSU's, and 4 RTX 2080 TI 11GB.  The rig is in an air conditioned space. 

I set it up to mine ETH with smos/metamask and wondering if the general recommendations for RTX 2080 TI change if you have a multi-GPU rig? 

For example, with 4 PSU's and increased cooling, can I crank up the overclocking a bit? 

Currently I set them all 4 to:

-200 Core MHZ
+1000 Memory
150 Power Limit
75 Target Temp
70 Minimum Fan Speed

Power is fluctuating between 148-151
MH/S is fluctuating between 55-56
Temps are fluctuating between 47-51 degrees celsius

Getting 223.24 MH/S and combined power output of about 633W. 

Any suggestions, recommendations to get the best performance out of my rig? 

Thanks!

You will only need 8gb ram, as for cpu u can use celeron so by the sounds of it u want to declock and devolt ur cpu too maybe.
Those power figure are from miner? or from the wall?
Seems like a 1300w psu would be heaps maybe 1600w to be safe ? 2x850w?
Temps seem good to me, must have some good fans.

Maybe list what current PSU setup is and what OS too.
Hopefully others will know more.

You can run the afterburner and might be able to lower the voltage of the gpus.
Nice rig, but for eth you dont need this much ram.
Most depends of ram speed (bandwidth) of the gpus.
So check if you can go a bit higher. 1100 or so.

Can I have a photo of your farm?
You are doing great.
For example, I would use cheaper components for the farm, and use the server for other tasks. Although it is possible that mining will not prevent you from using the server for your other tasks.

Xeon gold CPU is awesome but not needy since you won't be mining any CPU coins, if you have more free electricity use that CPU for verus mining or plot Chia coin, I've seen builds on YouTube that mine ETH and still plots Chia coins too

Those cards (RTX2080Ti) are working at their best hashrate I believe, if you are going to overclock make sure you don't go up too high because it will disturb your hash on pool or even start getting stales and rejected shares, the highest a rtx2080ti can do is 60mh

[swogerino]

You already seem to have the best rate out of the Rtx 2080 ti-s cards.They do 59.xx Mhsh for a card and that 223 Mhsh you have indicate that you are getting the most out of your cards.The Nvidia cards are great at achieving really good Memory Clock like you are already doing at +1000 and that pretty much for me is the best performance.You can though try to go higher little by little from this limit and see where the final limit is of these cards but I would suggest not do that as you are near the maximum possible hashrate for such cards.

There is nothing to talk about here mate, are you just showing off or what? Because RTX 2080ti can't do more than 59 to 61mh per GPU so what recommendation are you talking about? Just keep mining Ethereum and start counting your blessings, even if ETH mining is down today RTX2080ti is very good for other algorithms as well

I am not showing off....I have never mined in my life!  I actually don't even know what some of this means yet.  I was very interested in crypto a few years ago but stopped following any of it for several years.  

I actually didn't know what to expect, I was seeing some people on google saying they were getting 61 MH/s out of these cards and I am only getting about 57 or 58 MH/s on each card but I wasn't sure if there was a way to get more out of the cards if you have multiple working together, or if there was anything else I should be looking at.  

I have it currently set to:

Core:  -200
Memory:  +1500
Power Limit:  160w
Minimum Fan Speed:  65%

Each card is doing about ~1150/7549 and the temps are low 50's, putting out about 57.45 MH/s for a combined 229-230.  

I guess I am pretty happy with where it is at, if everyone thinks this about what I should be expecting.  

So far it looks like it has mined 0.0428 ETH in 5 days, 196 shares at 100% with no stale or invalid.  Stability seems rock solid based on simple minings chart.  

Seems about $32/day at today's ETH price which I am pretty happy with!  It looks like it will make my electricity bill go up by about $30 per month which seems very reasonable, I was expecting way higher!  At the current ETH rates, it seems I can pull in about $943 per month.....wow!

Once ETH2 makes mining less profitable I will switch it to Raven.  We have Raven mining on another rig and we already mined 678 coins in 4 days and have 3 other rigs we are going to put on Raven as they have crappier GPUs.  

Thanks for the input everyone, Ill try to post a picture next week of some of the rigs.  

Next I am going to learn about how we can add HD's and mine chia side by side - this rig has 20 hard drive slots I believe.......  I work in IT and I am pretty sure I have stacks of spinning disks laying around.  I just donated about 100TB worth of spinning disk drives to a recycler before I knew what Chia was

Yeah you now understand why no one can get a gpu.

30-35 in power to earn 943 is about 900 a month net.

which is simply amazing.
