i went with a LSI 9211-8i host bus adapter flashed to IT mode, expanded by a Intel RES2SV240. 28 ports available, can be expanded again to 48. I believe the expander (or maybe the HBA) can only handle 3GB/s bandwidth, but since these are all old and slow spinning disks, i'm not sure that would ever matter lol
edit: yea i bought homelab stuff because I want a home lab lol, and burst paid for it =D
@haitch my initial runs were without graphics card resulting in the same. without gpu's in the pci-e it does the same :/
I made a troubleshooting post at reddit which almost makes the main page, and still I can't figure out what it is... Im thinking a faulty out of the box motherboard or cpu but... Meh. pc building should be more fun :< this is just frustration
Lol, It's a 1986 IBM Model M.
30-31 years old. and works flawlessly.
Stuff just isn't made like use to be :( unfortunately.
It's dirty atm, I need pull the kcaps and wash them and wipe the kboard case down.
I believe you can find them for 40 bucks or so in good condition.
Gpu Miner ( jminer ) , tbh ur looking under 1 minute to search through your plots. so like a rx 560 or rx 570 :p
CPU should be used for plotting with xPlotter for optimized plots and that's pretty much it :p
they're so expensive they should be gold coated I mean they're the price of one of these Enterprise class things
It should have warp 9 considering its space age design the corners on it. If we're lucky it'll be on ebay for the price of new 8TB models in next 5 10 years.
@rnahlawi said in 31.1MH Eth 575MH DCR dual on MSI Rx 480 8gb:
Agree, but no mother board will take more than 2 cards
You might want to look at one of the 4-Way SLI /Crossfire MotherBoards. Eg.
Thou they generally don't come cheap (unless used). And you may need a CPU with more than 16 PCIe lanes (also not the cheapest). Some of the older X99 CPUs have 28 or 40 lanes for example. Plus, powering the GPUs directly from the PSU... And a Case with enough slots etc... And more cooling...
And after all that, is it still economic?
@Gibsalot Oh I see so we almost have the same rate in electric usage or yours is slightly higher.
I'll give an update to the comparison on reading time per block once I got it up and running.
Thanks a lot mate!
@BeholdMiNuggets Eh, I keep all my builds in simple text files so I mostly just copied and pasted from those and didn't bother with a picker list. :) Going E-ATX for a Burst miner is certainly ambitious, but it's also probably overkill. Once you get into high-end workstation or server builds, you start to run into large diminishing returns for your investment (unless you already have the hardware, plan to use it for other things, etc). Burst mining is meant to run on low-end machines and not draw a lot of power or resources, so I would advocate building multiple cheaper machines with normal ATX hardware rather than one monster machine. Besides inherently giving you more redundancy should a machine fail, there's also a limited number of add-on cards and devices you can connect to any given machine before things start bottlenecking or you just run out of IRQs, even if you still have slots or ports left on your mobo. Once you've stacked about 100TBs on one machine and you want more, it's probably going to be cheaper and easier just to build a second machine.
i wrote a tutorial about rejuvenation it increases throughput of any written drive. Just used it on my MyBook 8TB External. Although marginal, it increased the drives gain and i got a slightly faster throughput. Also, I deliberately did away with NTFS for exfat and transferred its plot from an internal pc drive using a 3rd party copying application to prevent fragmentation by using a large memory buffer adjustable in the app. NTFS can be a bottleneck on external disks is why exfat was invented. A fusebundle is available for linux to read them too.
@newsense2004 It's not cheaper if they all fail a year from now and you have to buy new ones. :) Also, 2 year warranty on the backup plus hubs, vs 1 year warranty on the regular expansions... minus two extra ports.
