    2bitmarksman got a reaction from leadeater in NAS Cache   
    For reference, if you connect a drive via iSCSI the CPU processing needed to write data to the iSCSI drive will be consumed on the PC that it is using it as local storage, not the FreeNAS host.
     
    Also to reiterate, unless you have 10g networking, don't bother with the SSD cache, and if you can, try to get an old server that you can cram a ton of RAM into instead like a Dell R710 if you need a highspeed cache. All the spare RAM that ZFS doesn't need on FreeNAS is used as the ARC cache, which is basically a RAM disk filled with the most used data you access. Once it fills, it cycles out the least used/old stuff to the L2ARC, if it has one, or just drops it if it doesn't. For reference, I bought a Dell R710 with 144 gb of RAM without drives and it was 538 bucks. Chelsio 10g NIC is like 25-50 USD and perc h200's are around 32-40 USD. HP servers can also be used and are a little cheaper but usually lower RAM capacities (128gb) and you would need an HBA (they don't have any that are compatible with FreeNAS that aren't for external enclosures).

    ZIL is good for lots of random writes (like running a bunch of VM's that all want to write small bits of data at once). Generally though, this really isn't needed for large file sharing in a home like Plex and a Steam library or anything that writes large files all at once.
     
    Oh, and make sure you setup Jumbo Frames, if you can. Big performance boost right there for lots of tiny files like textures for games over the network.

    Personally I'd recommend using Claymore and Mining either ETH, EXP, UBIQ or DBIX with your 480 if you want to mine. Nicehash is easier to setup but usually has lower hashrates and a higher fee than just mining the alt-coin and then converting it to BTC on an exchange.

    Also, you will want to make sure your cooling is sufficient on your card for mining if you want your card to live a good amount of time. Try to keep your card under 75C and the fanspeed on the card under 50%. you can check and manually set these things with MSI Afterburner to test things out. Above 80C and you're gonna start hurting the overclocking ability of your card in the longterm and above 66% fanspeed all the time will heavily wearout the fan as well. It would be a good idea to have some good case airflow if you wanna mine with your personal PC

    2bitmarksman reacted to DutchTexan in What is the best coin to invest in as of July 2017?   
    "The easiest way to think about what will happen is with some rough dates:
    July 21 — Segwit2x is due to be released and presumably all participants to the New York Agreement will run it. The miners currently signaling “NYA” in their coinbase transactions, or about 87% of the last 24 hours’ worth of blocks, are a good estimate of blocks that will mine using Segwit2x. July 23 — BIP91 should lock in (requires 80% of 336 blocks to signal) July 26 — BIP91 should activate. At this point, all blocks are required to signal for Segwit (BIP141) or they will be orphaned off the network. Around July 26–27 — This is also around when we can expect a new difficulty adjustment period to begin. The last one as of this writing was June 17 and they typically take 12–14 days (closer to 13 since new hardware comes online constantly). So June 30 (block 473760), July 13 (block 475776) and July 26 (block 477792) seem to be the next 3 difficulty adjustment period starts. August 10 — This is around when we can expect block 479808, which is the end of the difficulty adjustment period. Very close to 100% of blocks in this difficulty adjustment period should be signaling for BIP141 (Segwit). As this is above 95%, Segwit should be locked in. August 23 — This is around when we can expect block 481824, which is when Segwit should activate. From this block on, Segwit transactions will be legal on the network. This also sets the activation date for BIP102 on Segwit2x to block 494784 (exactly 144*90 blocks later). November 18 — This is around when we can expect block 494784, which is when Segwit2x should hard fork to 2MB blocks." https://medium.com/@jimmysong/segwit2x-what-you-need-to-know-about-the-2mb-hard-fork-27749e1544ce

    2bitmarksman reacted to ninjaelectron in So Whats Going on with Bit Mining?   
    A newish cryptocurrency has been making waves on the internet, called Ethereum. This has led to a spike in the amount of people buying graphics cards (mostly Radeon) to mine Ethereum, hence the lack of stock. Luckily, the difficulty of mining is skyrocketing, possibly leading to a future growth in the used market for GPUs in the coming months.

    2bitmarksman got a reaction from NorthwoodsAl in Advice on Etherum Mining   
    This is a good beginners guide to helping you get started with Eth Mining with the Claymore Miner.

    Note that the Claymore miner does show up as a virus due to the way the packer the Dev used to protect his core code. If you don't want to use Claymore because of that, or want a simpler way to get you started mining, then try Nicehash Miner.
     
    Claymore requires a bit more involvement but can usually provide better hashrates and dual mine both Ethereum and Pascal/Decred/some others, so more money can be made, whereas Nicehash is much easier to setup and more intuitive as its a GUI over CLI. That one is basically put in a BTC address, benchmark all the hashing algorithms with just the GPU selected and start the miner and it will mine whatever it sees as the biggest return for your card, but the hashrates are generally a bit lower than one of the dedicated miners like Claymore for Ethereum mining with AMD and ZecMiner for ZCash and NVidia cards respectively.

    Honestly, I recommend doing your own research because it will only benefit you from understanding it

    Frankly, I'm not so sure this will pan out the way they think, unless the prices are significantly less.  One of the "advantages" to miners using standard cards, is that they can sell them when they're done with them.  These cards have no resale value, due to a lack of output.

    What he said

    You don't run cards in SLi or Crossfire when mining, and Nicehash, Claymore and ZecMiner all have ways to select which GPU's you want to mine with. So you could have a miner mining on a card 24/7 and be playing videogames on the other just fine

    Around 200 watts of power. If you're entering total power consumption for a mining profitability calculator then a safe calculation would be around 350-400 watts (it's a little less than this I'm pretty sure but its better to plan for worstcase scenario :P)

    If you live a place I live, where electricity price is like around 0,05 €, maybe little bit more, but not much, even a power hungry 7970, using nicehash, make more money than its electricity cost.
    So if you look at the price you can buy it used, around 100 €, with 1 € a day, it would take 100 days making up what it is "worth".
    I am not running it 24/7 tho, because its my main PC. And I am not mining at 100%. And if the GPU died, it wouldnt be the worst thing, because I am planning an upgrade later this year

    2bitmarksman got a reaction from Marinatall_Ironside in Etheteum mining software recommendations, suggestions, and mining setup advice   
    Use Nicehash or a dedicated Zcash miner like ZecMiner for nvidia cards. The difference between mining ETH vs Zcash can be as high as 40% additional profits mining ZEC over ETH on nvidia.

    Nicehash is super simple to use, just need a BTC address, benchmark all the algorithms, pick the one with the highest BTC/day (may want to check each day to make sure you're maximizing your return) and start mining.

    ZecMiner requires additional setup and the extra step to get paid (that is turning ZEC into BTC on an exchange like Poloniex, then sending that BTC to an exchange that turns BTC into realworld money, like Coinbase. For this additional setup though will be able to make about 9-10% more profits per day over just using Nicehash.

    Have fun

    If you want to run Nicehash, benchmark all of them and then select the top 3 that will give you the most BTC/day (last column on the right). These atm are Equihash, Lyra2REv2 and Lbry.

    Also I generally recommend either not mining with the CPU or only mining with half its cores. The CPU will draw a lot of power and generate a lot of heat and really not contribute all that much to your overall profits per day. It's personal opinion but I would prefer to keep my parts working as long as possible rather than max out all it can for a shorter amount of time.

    Also also, Nicehash works by contributing your hashing power towards the hashing algorithms you select it to allow to run. Nicehash sells your hashing power, rather than you mining coin directly, so that's why they pay you in BTC rather than the coin you are directly mining.

    Due to the new architecture I doubt it will be good for mining straight away until the miner programmers can tune their mining programs. Also the nvidia and AMD mining dedicated cards should help alleviate the huge Out of Stock issues with the 470/480/570/580.

    The entire Intel i9 lineup is pretty janky, and the fact that it will be over 6 months until we'd see any of the main SKUs that consumer would want seems to say that it was a rushed decision to make this. It could entirely be scrapped if Threadripper were to be a terrible product (which I very much doubt based on its design). With that 6 months of playtime, the Threadripper line is going to be able to essentially run unopposed, along with allow another 6 months of growing pains to be addressed. Plus I'm sure when the i9 lineup would be released that AMD would implement pricecuts on Threadripper just because they could at that point.

    what is VME?
    also known as Virtual-8086 Mode Enhancements, it allows execution of real mode apps that cannot (were not designed) run in protected mode OS
    it's also used in hardware virtualization to emulate multiple x86 CPUs
     
    the Ryzen implementation
     
    what does it mean for the end-user?
    if the end user tries to run XP / WS2003 and earlier OSes, the system will either crash or hang - this affects both direct installs or through a VM
     
    not many end users need to run older OSes, but this particular issue can be problematic in a enterprise environments where they might need to run old OSes to keep their old equipment functional - if it ain't broke, don't fix it
     
    so far, reports have indicated Windows XP, Windows Server 2003, Windows NT, FreeDOS to have issues while trying to run on Ryzen CPUs
     
    the workaround, at least if you run a VM environment - mask out the VME CPUID bit (bit 1 in register EDX of leaf 1)
