And you can already see the first signs of such a tendence here in these threads about the new merit system. Juniors who are posting here to praise the system get plenty of merits, critical voices don't.
That is not entirely true, TMAN for example has given a lot of merit to users who openly disagreed with the change or criticized certain aspects. Others have been doing similar things, some more, some less. I also have given a few merits to people being sceptic, as long as they had a well explained position or provided some alternative they believe to be more suited. It's not about opinion not about agreeing with someone or disagreeing with them, it's about how you voice that opinion. People who outright cry and shout "No, no, no" without giving reasons or alternatives don't get merit. Posts like that are neither constructive, nor "high quality". If you make a well written post, explaining your position and opinion, bring something to the conversation, or just sum everything up really well, you will get merit, regardless of your opinion and stance. this is my take as well. merits should be awarded for posts with accurate, helpful information or clarifying a point of view in a concise way, not for some "old boys club" or "you merited me, so +merit for you" thing. whether or not you agree with that position. i have no problem with meriting a post i dont agree with as long as that post contributes to the thread in a meaningful way. this whole obsessiveness about rank seems blown out of proportion anyway. are there THAT many people in sig campaigns where rank makes a difference? i mean the only advantage to rank is sig campaigns anyway (aside from the recent "serious discussions" and "ivory tower" forums which are a welcome addition btw). i honestly dont know how many folks have sigs as i have sigs turned off so i never see them. the only sig ive ever had was a plug for cgminer back when btc was mined on gpus. personally ive never paid attention to forum ranks. now am i proud of my legendary status? sure, ive been here since 2011 and ive tried to help whenever i can. but i post when i feel like it and what i feel like. its not for post count or to level up. |

yeah that makes me nervous too. potentially ~2000 watts if your cards come up at full power due to whatever. are there any published specs on what the upper power limit per card is for this board?
Not many people will run the cards at the full power if there is electricity to pay. I only run them at around 60-70% to get higher efficiency. programs used to power limit cards sometimes fail for whatever reason. ive woke up to my cards at 100% a couple times. i still test my rigs at full power for a day just to stress test them and check temps at power outlets, psu connectors etc. that way no worries about the odd crash and reboot causing overheat problems with cards or melting connectors with all cards at 100% for prolonged periods when im not around. |

So if you're powering a GTX 1080 Ti that uses 250 watts and power is supplied by 2x 8 pin PCIe power connectors, you'd feed the power to the board on the short side. That single lead would give the board the bus power it needs and then the power for the cards would route through the board out the long side connector to a double headed PCIe power lead to the top of the GPU? I can see how cabling and wire management would be neat and clean. BUT, seems like you'd be pushing a ton of watts through the board as a result. yeah that makes me nervous too. potentially ~2000 watts if your cards come up at full power due to whatever. are there any published specs on what the upper power limit per card is for this board? |

For you guys running the ONDA D8P boards, did you need a "power button" to start the board? (e.g. short pins to power up)....
once you get the board powered up, use the setting in the bios to autoboot when power is connected.. you should never need to worry about shorting again. So the first/initial boot requires a short? no, mine fired up as soon as i powered up the psu. and it was set to power on after power failure by default in the bios from the factory. even a bios reset results in it powering up with the psu. |

People are mining on Nvidia these days?
yup, for alt coins. then exchange for btc. vs amd, they cost more up front but are more power efficient in the long term. Perhaps in the most simplistic terms(which..around here is not really a bad thing). Its really more to do with the Equihash algo...it runs better on Cuda than OpenGL..so where before..AMD had the advantage on hashing sha-256(way back..pre-asic) and scrypt(not so way back but still a couple years ago) today's markets are filled by both...perhaps I should say empty of both? -random thoughts- It comes down to architecture..AMD has been behind machine learning and large data set simulation since CNG became a thing. They have expanded with Vega and Infinity Fabric. Modular SoC are here. Being able to just add compute complexes as needed is a game changer. TSCM..one of the largest nodes for producing wafers...over half of their production is running a 16nm ASIC process..not gpu or flash memory. Why do I mention this? Because the supply is not just suddenly going to grow. All current cards are getting snapped up at a premium. Something similar happened in 2014. GPU mining is not going anywhere. Whether or not it will be profitable is up to the market. yeah i tried to keep it simple. amd is generally better on some algos, nvidia at others. and even within the amd and nvidia lines some models are better at some algos than others (say 1070 vs 1080ti on nvidia, or 580 vs vega on amd). makes mining a with a mixed rig like mine more fun. back when i mined btc on amd gpus the VLIW4 vs VLIW5 generation was a big deal if i recall correctly. |

Also people going CRAZY over GPUs. People basically paying $1500 for GPUs and Computer Stores either Out of Stock on PSUs or REFUSING to sell PSUs without a Mobo+CPU combo.

I need a new water heater, I'm considering installing one of those heat pump units in my mining room also.
just be aware heat pump hot water heaters will need to drain condensate somewhere. |

how are you controlling case fans on the ONDA 8 gpu board ?
I got two fan header splitters and have 4 140mm maglev fans on the board , actualy i want to do six with splitters eventually
I noticed some of the fans are not spinning at max speed I have two in the back blowing towards to front , and two in front set up as exhaust fans
how do you set the fans to to basically go at max speed or at least 80%
these are PWM fans btw
i just used a 4 channel fan controller powered from a molex. if all you want is 100% they make molex to pwm adapters that should run your fans at 100%, but a quick search shows they are kinda pricey for what you get. something like that? $15 though kinda pricy , but the cheapest i could find this would allow me to set all the fans to say 80 percent right? yes something along those lines, something with a rotary control to set speed. cant comment on that particular one (the spelling is crazy bad and that doesnt inspire confidence) but thats the idea. set anywhere from off to 100% manually. |

okay I am building a rig for a guy using the b250 version 1 onda.
he wants windows. and I loaded windows 10 did the up date loaded nvidia drivers booted and I am at black screen.
pissed to say the least. any guess at what to do next.
I tried a few tricks but going nowhere fast here.
Hi Phil, I put windows on the Onda B250 you sent me this past Sunday. I played around a lot changing bios settings, got a black and then a grey screen. I was connected to an Nvidia card, not to the internal GPU. I was also connected to the network. I ended up hitting the clear CMOS button by the 2 USB ports. That at least got me to the screen where I could enter the bios settings again. This time I think I only changed PCIe speeds from max to Gen1. Rebooted, loaded windows from a USB stick, install went fine. I'll check over the weekend, but I am pretty sure I did not enable the 4G option, which you have to do on Asus Z270 boards. Can check all the other settings as well and I will report back. But bottom line, same exact board and Windows is running fine. For memory I used the G.Skills stick that either you or someone else on here posted the link to NewEgg. phil, here are some shots of my onda b250 d8p v1 bios, its running win10pro display is running off the igpu (the boards HDMI plug), cards have nothing plugged into them.  https://i.imgur.com/7J3nPzi.jpg?2 https://i.imgur.com/icq2Wua.jpg?1 https://i.imgur.com/Nz5Fssv.jpg?1let me know if you need something specific you want shots of |

Hey hows peoples experience with running AMD cards like the 570/580/Vegas on the Onda D8P motherboards, all I see is them running Nvidia.
I want to know since AMD cards, unlike Nvidia, pull a lot of juice through the PCIe slots, so if anyone's done an 8 card build and its running stable, I'd love to hear about it, maybe see some pictures.
not all amd, mine is mixed: i have 2x470s and a 460 on my d8p (other cards are 2x1080ti, 1070ti, 1070) runs fine, fwiw |

If y’all are wondering why you’re not receiving replies…
As predicted, if y’all click your Profile →Profile Settings →Personal Message Options, you’ll notice that “Allow newbies to send you PMs.” is unchecked. This change was apparently made automatically recently to every established member’s account so as to prevent Newbies like myself from private messaging you...
Interesting. Though on checking my profile just now, “ Allow newbies to send you PMs.” is checked (I've never edited the setting). Have they changed it back again I wonder? mine had been unchecked. and i sure didnt do anything. |

Out of interest, has any of you tried a riserless board with non-blower-style GPUs? Surely they're too close to eachother to work efficiently, i.e. heat cross-contamination must be terrible?...
onda b250 d8p with 2.5 spacing  https://i.imgur.com/PRSrodh.jpg?1sorry for poor picture just wanted to get something up quick to show the spacing. |

I will be doing just that - and yes, they are awfully close together. I'm planning on using supplemental fans to blow air either down onto the cards or across from the side opposite where the video jacks are. some riserless boards by onda have more spacing than others. the b250 d8p v1 has 2.5 spacing, some other models ive seen are only 2. the d8p gives a decent amount of room between cards if they are double wide. i still use fans to force more air through though. all non blower type cards here. |

@hardwarewallet: I think you are over a bit here. I have read your blog post explaining Meltdown and Spectre for the average person. Nice summary. I wonder how you can say, router OS or hardware wallets are secure. I cannot see how you derive this.
youre kinda missing the point. at least on the trezor, it only runs its own code in its firmware. it never executes foreign code, so there is no way to get something to run on it to exploit something. now if the firmware gets compromised then it could steal stuff via exploits, but at that point the compromised code can do anything it wants anyway, it hardly need to use an exploit. meltdown and spectre need to get code on the device to run to exploit them. |

Looks like it is getting interesting. So Uncle Stu wants to hide his shit, Shinners wants to see his shit...  thanks for keeping us up to date. i live about 45 minutes from hartford, i sooo wanna make a day trip there to see this go down when it happens. |

Are there any plans to support BIP70?
People can't pay BitPay invoices with their Trezor anymore, which is a very bad experience.
It's not an immediate plan for them as already explained by the CTO. I believe both Electrum and Mycelium support BIP70 so you could use them with Trezor in order to pay. mycelium on android does support bitpays new format (bought stuff off newegg with it recently), so you can use the trezor that way for it. |

Hi I need some help with Onda D1800 BTC, the mobo arrived without bios battery, what kind of battery I have to use, Lithium CR2032 is the correct one? Is available the scheme to connect power button and status led to FP1 connector?
Thanks in advance W_M
CR2032 confirmed for Onda D1800. My seller actually informed me of the fact they were not allowed to include the battery in the package from China. Just buy one (costs next to nothing), plug it in and off you go! yeah any of the bigger drug stores chains should have em (cvs, riteaid for example) if youre in a hurry. |

So much FUD in this thread. I have written up a blog post explaining Meltdown and Spectre for the average person (who has some familiarity with computer terminology). The NSA has no interest in stealing your Bitcoins. If they are stored on your PC and the NSA wanted to steal them, believe me, they could steal them and the Meltdown and Spectre attacks have nothing to do with how they'd take them. For most people, a hardware wallet is the best way to keep your coins secure. Hardware wallets are not vulnerable to the Meltdown/Spectre class of attacks.You got any more info on this? What CPUs are hardware wallets using? Spectre is pretty wide reaching, even some ARM chips are affected, so I am quite curious about architecture hardware wallets use, since there are not many CPU manufactures in the world. doesnt make any difference what cpu the hardware wallet is using, its running signed trusted code from the manufacturer 100%. no way for the malware to get in. trezor had a side channel attack (power draw analysis) a while back but thats been fixed for a long time. |
