hi all!!!
no experience here, to a mash up mining rig, for burst and ETH??
i explain better.
I want to buy a 7 PCIe mother board with 6 RX470 Nitro 4 gb and on the seventh PCIe plug an adaptec SATA controller for 8 SATA drivers...
Do you think my PCIe bus will support all this traffic???
If yes i can mine with the same RIG, BURST and ETH.
I have been running a mining rig since 8/2014 on a fat 32c machine with 6x PCIe (Gen2) slots.
Never had any io-bottleneck, and this is a very busy machine.
I/O:
To mine 1 TB you have to read 1TB/4096=256 MB.
If you want to finish in under 60 seconds, that is 4,5 MB/s of bandwith for one minute every 4 minutes.
Now lets say you connect 8x 8TB disks to your rig, that would mean 286 MB/s of bandwith for one minute every 4 minutes.
I/O wise this is nothing, a single SSD yields about 500 MB/s.
compute:
If you have a AVX2-capable CPU, the computing takes up just seconds per block (4 minute block time).
I just ran a test; on my 2.1 GHz E5 combing 60 TiB takes 140 cpu-seconds (divisable by number of cores that you can spare for this).
The speed increase is (nearly) linear w/regard to clock speed, so you might easily get away with 2 cores @ 2.5 GHz for 64 TB in under 60 seconds.
Using a SSE4-only CPU roughly doubles the CPU time, using (part of) a GPU (via opencl, support included in the java-wallet) is faster by
a factor of 2-10, depending on your GPU.
plotting:
I did most of my plotting on several (now historic) 280x, yield was 170 MB/s per GPU.
To put this into perspective, the AVX2 code on 2.1 GHz gave me 3.8 MB/s per core. SSE4 is about half of that.
hint: If you're going the manual route (like real men do), use large files (500+ GB), plot to a temporary target,
optimize plotfiles from temporary to the final disk. I have no idea about the AIO package or Windows in general.
just my 0.02.
wow..
this is really usefull...
so, many thanx to you vaxman!!!
you are very skilled!
now another question...
i know who it's very dangerous do largest RAID0...
1) but do you tink it's more profittable for performance, mine all burst plots with gpu ove 4 separate HDD (D:\, E:\, F:\, G:\)?
2) or mine plots with CPU but over on a RAID0 array with mine 4X8TB hdd???
i think the response is with all together.. but i can't..
so, what is better???
Config 1) or 2)
thank you
