Wow that's impressive! I though it got much lower with the increased DAG file. What power consumsion does it? Why only half in Windows?

It's still very profitable nowadays I assume? Anyone having a modern rig of R9 390 8 GB?

I'm quite interesting what a R9 390 8 GB does on ETH nowadays. I mean with lolminer 1.22 and proper tuning. Anyone has one?

For mining Ethereum on 4 GB cards I recommend lolminer. My rig also crashes random within 5-15 mins with TRM on 4 GB cards.

My Vega 56s kicks ass! They are really nice, all doing 50+ MH/s @ ETH. I love them actually!

Before Ethereum I mined Vertcoin very well on them, and before that they were a beast at Monero! Not to forgotten Electroneum, but that's another story

Hi there! I have been mining ETH for a while and my rigs are working just fine!

But, when I switch to mine to NiceHash I get a lot of rejected shares. For about one hour I got 230 accepted shares and 6 rejected shares. Is there a good fix for this?

I'm running --eth_stratum_mode=nicehash but nothing more.

No three RX 580 will draw a little bit more watts to archive 100 MH/s than one RTX 3080. But there one very important aspect to consider, RX 580's is a LOT cheaper. That's like the most importent parameter I'm looking into when buying GPUs for mining.

Well now, no GPUs are cheap, that's why I don't buy any at the moment either. Never buy GPUs when crypto is high and demand it high for GPUs, that's really dumb!

Can you please explain how do you go below 800 mV?

I have an ASUS TUF RTX 3080 in my gaming rig. I have tested to mine Ethereum at 97 MHs @ 220 W. No problems there, but the temperature is like 47-50C, but the fans are running at 75%. Why are the temps so low? But I think they arn't..?

My RTX 2080 Ti showed like 65-70C @ 60 MHs.

Anyone else noticed this, seems like the card is getting hotter than it shows? I assume the VRAM is getting hot as hell? No temp for VRAM sadly..?

It's totally safe to only plug in one 8 pin PCIe into Sapphire RX 580s. I'm running my 12x RX 570/580 that way, and it's hashing away just fine. The second 6 pin is just if you want to deliver more power (overclock the GPU much). You don't want that with mining.

You are doing it right, down with voltage and core clock (around 1100 MHz is the sweatspot.) And I been able to get voltage to 800 mV (even lower is possible), but it all depends on the ASIC chips and quality of the GPU. Memory clock is typical around 2000 MHz.

I'm recommend OverDrivenTool as tuning software for Polaris cards. It's very straight forward and easy to use. You can also make a batch file so you automatic set the clocks/voltages when you'r satisfied!

Well you can't use Threadripper on that motherboard. You need a motherboard with socket TR4 for Threadripper 2950x. Also I would go with more RAM if you should CPU mine on it as well. Better buy a Ryzen 3900x or something if you are planning to CPU mine, more cost efficient.

Also, the power supplies are a bit over powered, even for that system. Go with one 1600 and one cheaper maybe like 750 W. If you run it efficent you will consume like top 200 W per GPU.

Thanks for explaining, that makes sense. 

I have some problems when mining TurtleCoin. After some hours or so, GPU5 dies, but as it seems, it hashes quite good actually.

How come?

I should say Monero or VertCoin maybe?

I have notice that power consumption at Chukwa is much higher than on CNR all across the board (Polaris/Vega/R7). How come? Or am I doing something wrong? I have even lowered clock the frequences against CNR.

Ex. 12x R570/580 @ CNR 10820 H/s @ 960 W from the wall. Same rig at Chukwa is doing 702 KH/s @ 1250 W. Is this normal?

Sapphire RX 570/580 8 GB. But I'm running my GPUs at low clocks ~1100 MHz Core/~2000 MHz Mem @ 800 mV. What frequency/voltage do you run to achive 33 MH/s, it can't draw low power?

At another miner I'm getting 30.5 MH/s at same clocks/voltage.

I havn't tried PhoenixMiner that much before on my 12x Polaris rig. It works just fine, but I don't get that high hashrate with the miner, as of another miner. Anyone have some tips for me to increase hashrate. I have tried -clnew -clkernal 1-3. Doing autoconfig aswell.

I'm getting like 29.8-30.2 MH/s at 1110 MHz Core and ~2050 MHz Mem.

AMD Ryzen 3900x is the best CPU imo (it's great at cn/r also), it has a large cache that both CN/R and RandomX loves, totally 70 MB. You don't need much RAM or a fancy motherboard (x370/x470/b350 is really enough).

I have one that I bought when they came out. Have nothing bad to say, it works like a clockwork I'm mining mostly Ethereum and Monero with it.

If I would buy one today? No, but I would not buy any new GPU for mining today.

Thanks! It was that easy, I had a little too little swap, when I extended it works just fine, thanks!

I'm having some issues when trying to mine Grin 29/31. Just assigning the GPUs with 8 GB. MTP works fine. If I also exclude the last GPU, it works.
