    Yup.

    The ASICs were defeated in Monero, at least for now. It should mean substantially more revenue from PoW of GPU owners, despite the low ratings of all cryptocoins so far.

    Meanwhile the ethereum guys afaik still don't even know if they want an anti-ASIC (meaning anti-centralization) fork.
    That should raise some brows..

    Even people with NVIDIA rigs are jumping ship to XMR right now, so the network hash rate has increased to 372MH/s. Stellite is actually more profitable right now.

    One very important thing to note here is that Bitmain was indeed mining XMR with ASICS in secret, probably ever since December or even before that.
    People were suspicious about it but there were no means to prove it until the PoW change.

    And as soon as the PoW was announced, Bitmain started selling these ASIC solutions online as the Antminer X3 (their cryptonight solution).
    Furthermore, all the fools who ordered the X3 from Bitmain confirmed that these units had clear signs of long term usage in them (dusty fans and interiors).
    Bitmain is downright scary as to how underhanded they're legally allowed to be.


    XMR may seem safe from centralization, but no one really knows how many coins Bitmain owns right now. Seeing how each X3 was mining at ~220KH/s @ 500W (this is >100x more than a BIOS-optimized Vega), then Bitmain probably already owns most of the XMR mined so far.

    Almost all the Vega cards in the world were mining XMR, and that amounted to around one third of how much Bitmain were taking to themselves.



    Yup, XMR is now the only not-unknown alt-coin to mine with GPUs.
    And if it's profitable now with the current crypto prices in the gutter, then as soon as Bitcoin recovers to ~10K (if ever, but it's probable) it will be crazy profitable like never before.
    Then we can all say goodbye to consumer graphics cards. Again.




    P.S.: In the meantime, I just can't get my Vega 64 to mine more than 1.7KH/s on XMR-Stak, no matter what settings I use.

    $800 for that new Antminer is a great price, but it only does Ethash...So when all these ASIC miners hit Ethereum the difficulty is going to jump making the coin/hash very low.

    At least the GPUs can go after sh*t coins thereafter.

    Also, for those who don't know, antminers are absurdly loud. I have two and I've already relocated one to a data center and the other is heading that way this week. In spite of a large house with that one Antminer stashed in the far corner of the basement, I can still hear it in my bedroom (though it's not terrible there).

    Holy hell re: Bitmain mining XMR in secret!
    If they can't be trusted not to sell used hardware, etc. how can they be trusted to not manipulate XMR transactions assuming they control over 50% of the hash power?

    You neededn't be alarmed.

    I've noticed there's a pattern to wtm's listings. When there are wild fluctuations in hashrate (or dificulty or whatnot) of a coin, it gets delisted for a while until things settle down. ETN got the same treatment. You can find XMR by looking for the individual calculator though : http://whattomine.com/calculators

    What settings and drivers? I’m steady at 2050 h/s at 1426@875mV core and 1080@870mV HBM. Vega FE.

    Intensity 2016, dual thread, Blockchain driver.

    Intensity 1600, dual thread, latest 18.3.4, max state P5 meaning 1398MHz I think, HBM @ 965MHz, voltages untouched, Vega 64.
    HBM2 temps at ~60ºC with fan running at 2250 rpm.

    Increasing intensity to any more than 1600 dual-thread makes the hashrate drop hard to dual 300H/s or so. Messing with power limit makes little to no difference, with -40% decreasing power consumption by ~10W with no performance impact.

    Have you tried increasing one thread to 1932? And did you set Virtual Memory in Windows?

    I only use OverdriveNTool, so have no experience with Wattman.

    XMR Monero mining Hashrate & Difficulty have now somewhat stabilized. Hashrate peaked at 1.15 MH/s pre-fork then dropped to the low of 175 MH/s right after the fork then with the flood of farms targeting XMR the Hashrate move up quickly to around 550 MH/s. Over the last 36 hours Hashrate & Difficulty have been slowly falling while Profitability is increasing which is good for us mining XMR.

    From this chart of XMR's Hashrate it appears that ASIC mining started 1/30/2018. Before that date the Hashrate averaged 650 MH/s but from 1/30/2018 until the hard fork happened the Hashrate averaged around 975 MH/s or 50% higher. Clearly that was ASIC mining.

    In December we were at 300 MH/s. I reckon the ASICs came online gradually even earlier. 2017/08/25 = 156 MH/s. 2017/08/27 = 233 MH/s. Nearly 50% in just 2 days. It could just have become the most profitable coin at the time. Incidentally we were back briefly at 157 MH/s just after the fork.

    The 6 month chart does show the gradual increase from 300 MH/s to 600 MH/s but that took two months to do. I believe that was mostly the rise of the bot-nets. The move from 600 MH/s to 900 MH/s only took 7 days. That was defiantly ASIC.

    It is good to see XMR profitability above $2 per KH/s. Other than the day of the fork the last time it was this high was Jan 28, 2018 just before the ASIC miners started running.

    Difficulty 59.922 G -3.94% in 24 hours

    My small farm has now grown and is currently producing 22.3 KH/s mining Monero XMR.

    ASICs were mining before January though. Sounds like a nice rig, is it just VEGAs?

    If they were they were only prototypes and not many of them. The rise from 300 to 600 MH/s took two months that was most likely because whattomine was showing Monero XMR was the most profitable coin to mine.

    https://bitinfocharts.com/comparison/monero-hashrate.html#6m

    In fact that is what is now happening again as Monero mining profitability rises above the $2 per KH/s more farms get pointed at Monero and hashrate increases.

    Difficulty 60.649 G -2.44% in 24 hours
    Hashrate 534.187 Mhash/s +8.07% in 24 hours
    Monero Mining Profitability 2.0388 USD/Day for 1 KHash/s

    https://bitinfocharts.com/monero

    January 28, 2018 is when the production ASICs were starting to come online. The jump from 600 MH/s to 1000 MH/s only took 11 days and stayed at that level until the fork even though profitability dropped dramatically.

    Well, just came to say that, as per my promise, I'm not mining anymore at the moment.

    The weather got really (really!) warm here, so PCs are off. Which is a bit of a shame because I think I was making more XMR now with just the Vega PC connected than what I was making during the winter with the two PCs (Vega/10-core + RX480/4-core) at the same time.

    I did only ~1.5 XMR as a whole, which is not a lot but I'll hodl it to my grave.
    Well, not to my grave as that would be really counter-productive, but you get the idea..

    I do have three Vega 56's and they are producing 5.9 KH/s of the 22.3 KH/s. The remainder is from a hodge-podge of various systems mining on CPUs and GPUs.

    Three HP DL580 G7 Servers each with 4x E7-8837 Xeons producing 4.8 KH/s on just the processors. Right now I have 17 GTX 750 1GB GPUs on these systems which brings the hashrate for these systems to 8.7 KH/s.

    I will be adding 10 more GTX 750 GPUs to these systems (9 per system) and then with tweaks to the XMR-Stak Nvidia config for the GTX 750's should result in 11.3 KH/s.

    I have two HP Z400 systems that house the three Vega 56's. These have an Xeon X5660 hex-core processor. One Z400 has two Vega 56's the other a single Vega 56 and a GTX 750. The processors and GTX 750 add 0.7 KH/s.

    I also have four Dell T3610 systems that have E5-1620 V2 Xeons. One system has two GTX 750 Ti's and the other three have two GTX 750 in each of them. These are producing 3.6 KH/s.

    A Supermicro dual AMD 6338 Opteron Server with three GTX 750's produces 1.6 KH/s.

    A Dell T5600 with dual 6-core E5-2640 Xeons and two GTX 750's produces 1.3 KH/s.

    My main workstation is a Dell T5500 with dual X5687 Xeons. I am only using the processors which produce 0.5 KH/s.

    Right now power usage (and heat) is an issue and I am addressing that by installing two 240 Volt 20 Amp circuits to power two 16 Amp PDUs to power six servers that will be installed in my garage. I have a very large workbench with a wall mounted AC unit above it. I plan to put thermal curtains over the workbench so that the AC can cool the servers in the summer months.

    This article explains why to use 240 VAC over 120 VAC household circuits.

    Density – Electrical 102
    http://www.cointainer.life/2018/02/22/density-electrical-101

    Of the systems above I will be selling the Supermicro Server and the Dell T5600 and adding the GTX 750's to the HP DL580's.

    I also have a couple of Dell R815's with quad 12-core Opteron 6234 processors that I plan to bring online.
