As long as you don't duplicate nonce ranges, you can plot on as many machines as you want to.
BURST mining on the CPU uses very little CPU power most of the time, it works fine on my 5 card rigs with no noticeable impact on the GPUs doing their mining.

Returns though are very low, and the pools issue has been a major pain for a few months now - seems like someone(s) have it in for BURST and have been DDoSing the pools right left up down and sideways.

Did some testing last night on my 1070 ti cards - and NO hashrate change under LINUX when I moved them from +700 core to +900, +1100, +1200 (didn't bother testing past that point).

It does appear that LINUX works with "effective" clockrates though not with the base clockrate like Afterburner does, based on some testing I did on 1070 cards (none of which would run stable at +550 or higher under Windows, but were ALL comfortable at +900 under LINUX with noticeable ETH hashrate gains).

ETH does use CPU - just not very much of it unless you're doing DAG file creation on the CPU like older Genoil versions, and even then it doesn't use a lot for long.

Equihash seems to depend on the miner version - but generally doesn't use much CPU either.

No, the board does NOT support the use of more than 13 "non-minining-specific" cards of one brand even under LINUX - ASUS did something weird in the bios to limit it for no apparent reason I can see.

All of my 4+ year old cards are AMD, the oldest NVidia cards I have are "only" about 2 years old and spent a lot of their lifetime Folding (which tends to be HARDER on a cards than most cryptocoin algorithms are).

I mount one NMB fan to each heatsink, 2 per card.
I MIGHT be able to get away with one fan per card, but the spacing between the heatsinks would make that problematic as a lot of the airflow wouldn't go through the heatsinks at all that way.
I COULD mount one fan to the heatsink at the "end" of the card near the power connector and get acceptable cooling for the GPU itself, but I worry about the stuff UNDER the heatsinks getting enough airflow if I try to do that.

I have a ton of fans sitting around though, bought a batch of something like 20 of them at a hamfest decades ago for $1 or $2 each, so using 2 per card isn't an issue for now.
I also have quite a few other "leftover" fans from CPU heatsinks out of "retired" Athlon-era and older machines if I run out of the NMB fans.

 You young pups - I first learned to program on a PDP-11/70 - about the same time CP/M first showed up.

 "Copy Is Backwards!"


If CP/M tried to show up 10 years later, DEC could have sued for "look and feel" violation as CP/M's user interface was pretty much the RT-11 user interface (and very similar to the RSTS/E interface).


The oldest machine I ever actually worked with was a Bendix G-15 - but to be fair it was old when I encountered it, almost as old as I was.
DRUM for main memory, and average access time measured in a lot of milliseconds.

It appears I have 2 from different batches, one has the BIOS switch one does not.
Weird stuff, I bought them in the same order from Newegg.

I've had many GPUs survive 4+ years of high-load usage running in the 70-75C range.
Targeting 50C is WAY excessive, and the only cases of 50C GPU temps with 50% or less fan I've ever had were on gear in an A/C room on risers, or the "outside" card in a "no case" rig with all cards on the MB, or a rig with ONE card in it - and the card was set to run at "efficient" settings.

Water cooled/hybrid is another story, water cooling the GPU is a lot better at keeping the temp down - at a significant cost for the higher-end cooling solution.

To date, HBM used in video cards is NOT on the same silicon, much less in the same package, as the GPU, though that might change when the Bristol Ridge APUs get released.
It does tend to be clustered a lot closer TO the GPU though, than ram on a motherboard.

 It's a pain but it's possible to replace the Gigabyte fans without removing the shroud.
 Getting to the power connector for the individual fan is the BIG issue, and getting it routed correctly for "no wires in the way" after swapping the fan are the biggest pains - the screws for the fan aren't a big deal.

After looking at mine, they DO have dual BIOS - though the switch is not real obvious and tiny.

Very wide variation depending on Ball Bearing or not, and on the specific card.

I've had a couple Sapphire cards with very small fans that need 80% to say reasonably cool run at 70-80% for 4+ years without issues.
I've had Gigabyte 3-fan Windforce models die in a year or less with 60% fan.


I generally aim for cards to stay in the 65C range on my AIR CONDITIONED workbench, so that when they go in the "production" room that runs a lot warmer in the summertime they'll stay in the 75C or less range - and the fan speed ends up wherever it needs to be.

Riser rigs help a LOT on that, much better airflow and less heat hangs around so you can set your fans 20% lower in many cases while seeing LOWER temps.

1070 ti and 1080 at their most efficient point (around 104 watts) tend to have better hashrate out of the 1070 ti *BUT* I do have a couple cases where the hashrate is the SAME (Zotac Mini, EVGA SC).

1080 tends to want less +core and usually doesn't handle as much +ram before it goes unstable.


 Down side, at NORMAL pricing the 1080 was around 10% more expensive for "same model" cards.

Amazon has been running a "cloud" service for many years - and no, it's NOT profitable to use it to mine with even if you don't get caught doing so (it's a violation of TOS to mine on their servers due to the "excessive load" mining puts on them).

Most HBM usage DOES have the RAM on it's own die.
Reference the AMD "Fury" line, and their current "Vega" line.
I'm pretty sure that's also the case for the Titan V and the Tesla "volta generation" on the Nvidia side.

It's still a bus, it's just a very WIDE bus (4096 bit IIRC?).

*ROFLMAO*

The Gigabyte 3-fan Windforce models I have recently replaced fans on were more like *1* year old and spent that time in the 60-70% range.

Like I said, JUNK fans.

Most water cooling setups keep the GPU noticeably cooler than air cooling manages - at a cost as the systems are expensive compared to air cooling.
They probably use a bit more power though, as they tend to use a higher-end fan on the radiator AND the pump uses some power.
Might be close or a bit less power though, as the fans they use TEND to be more efficient than the very thin fans air-cooled cards have to use.

Near identical environmental conditions and speed history.
In theory, they SHOULD fail at the same time, but there is a HAIR of difference between 2 fans on the same card + manufacturing variations cause a little difference.

The ones I use COULD plug into the GPU power (they use LESS total power than the original fans), but I find that setting them up on a MOLEX to run from 5 volts gives plenty of airflow AND very low power usage.
They're not PWM so there's no real point of trying to set them up on the GPU power connection.

They were ball bearing during the LITECOIN GPU mining craze, so years ago.
I don't remember a time they were junk, but I did spend several years ignoring discrete GPUs 'cause the on-MB video chipsets were "good enough" for anything I was doing for a long time, then the A10 iGPU took over.
