Positioned casually amist the current and upcoming power supply lineup at EVGA's suite at CES is the SuperNOVA 2200 P2, which offers a mere 2200 watts of 80 Plus Platinum power with 183.3A from the +12V rail. I will let that sink in for a moment.

Naturally this level of power will require more than the typical 110V mains power in the US, with 220V required. It seems safe to assume that the biggest customer of such a PSU at this point would be the mining community, making the need for 220V a non-issue for the dedicated miners among us (who needs an electric range in the kitchen, anyhow?).

We didn't get specifics on release date or pricing, but this is an impressive piece of hardware - especially considering the Platinum efficiency.

Nicehash Hacked To Tune of $66 Million Worth Of Bitcoin

Tagged: nicehash, mining, hack, Cyber Security, bitcoin

In a recent press release cryptocurreny mining market Nicehash revealed that its payment service was hacked and its BTC payment wallet was emptied. While the company did not reveal the exact amount lost, users on Reddit spent the better part of today worried as the service was initially "under maintenance" for 12 hours amidst suspicious transactions on the blockchain that saw 4,736.42 BTC taken from Nicehash and their Nicehash internal wallets reporting zero balances. The company is currently investigating the precise amount stolen, though estimates around the web put it north of $66 million USD worth of the popular cryptocurrency (at time of writing 1 BTC = ~$13970.50).

Users that mined to an external wallet for an additional fee are out unpaid balances less than 0.01 BTC, but sadly users that mined to an internal wallet have potentially losts hundreds or thousands of mined bitcoin. Also, purchasers of the Nicehash mining service may have lost the BTC that they paid into the service for alt coin hashing power.

"We are fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity.

We would not exist without our devoted buyers and miners all around the globe. We understand that you will have a lot of questions, and we ask for patience and understanding while we investigate the causes and find the appropriate solutions for the future of the service. We will endeavour to update you at regular intervals."

Nicehash is further recommending that users of its internal wallets change all of their online passwords (especially any that were similar to the one they used on the site) as a precaution.

The full press release is available here.

In all, it is a devastating hack that is another in a series of high profile crypto currency heists that have traditionally left users out money and the company destroyed. Nicehash has indicated that they have reached out to and are cooperating with the relevant authorities, but unless they are able to find the individual(s) responsible and recover the massive amount of bitcoin it is not looking good.

I hope that the bitcoin is able to be recovered or at least that Nicehash is able to do the right think and compensate its users from its own funds.

This high-profile attack further illustrates the need to use safe bitcoin storage practices and to always hold your own private key in an offline wallet (hardware or paper or at least encrypted software wallet you control at a minimum) for long term storage of funds. Your crypto currency is only truly yours when you alone control the private key(s) and you should only transfer and keep coins on other servers (e.g. exchanges) for as long as it takes to transfer them to your bank or as short a time as possible when trading.

What are your thoughts on this? Did you have money in a Nicehash wallet or unpaid mining balance? Do you plan to venture forth and mine on your own?

AMD Is Very Pleased To Participate in Blockchain Technology

AMD’s CEO Lisa Su was recently appeared on CNBC’s Power Lunch Exclusinve interview segment where she answered questions about bitcoin, blockchain technology, the tax reform bill, and sexual harassment in the workplace.

AMD CNBC.png

Of particular interest to PC Perspective readers, Dr. Lisa Su shared several interesting bits of information on cryptocurrency mining and how it is affecting the company’s graphics cards. Surprisingly, she stated that cryptocurrency miners were a "very small percentage" of sales and specifically that they represented a mid-single digit percentage of buyers (~4 to 6 percent). This number is hard to believe for me as I expected it to be significantly higher with the prices of graphics cards continuing to climb well above MSRP (it wasn’t too bad when writing our gift guide and shortly after but just as I was about to commit I looked and prices had shot back up again coinciding with a resurgence in mining popularity with the price of cryptocurrencies rising and improving ROI).

Further, the AMD president and CEO states that the company is interested in this market, but they are mainly waiting to see how businesses and industries adopt blockchain technologies. AMD is “very pleased to participate in blockchain” and believes it is a “very important foundational product”. Dr. Lisa Su did not seem very big on bitcoin specifically, but did seem interested in the underlying blockchain technologies and future cryptocurrencies.

Beyond bitcoin, altcoins, and the GPU mining craze, AMD believes that gaming is and continues to be a tremendous growth market for the company. AMD has reportedly launched 10 new product families and saw sizeable increases in sales on Amazon and Newegg versus last year with processor sales tripling and double digital percentage increases in graphics sales in 2017. AMD also managed to be in two of the three gaming towers in Best Buy for the holiday buying season.

Speaking for AMD Dr. Su also had a few other interesting bits of information to share. The interview is fairly short and worth watching. Thankfully Kyle over at HardOCP managed to record it and you can watch it here. If you aren't able to stream the video, PCGamer has transcribed most of the major statements.

What are your thoughts on the interview? Will we ever see GPU prices return to normal so I can upgrade, and do you agree with AMD’s assessment that miners are such a small percentage of their sales and not as much of an influencer in pricing as we thought (perhaps it’s a supply problem rather than a demand problem, or the comment was only taking their mining-specific cards into account?)?

Cryptonight mining with Chrome

Tagged: cryptonight, chrome, mining, security

Have you noticed your Chrome sessions are using a lot more CPU power now than they used to and you have installed the Short URL (goo.gl) extension recently?  Congratulations, you are a cryptocurrency miner!  It seems some ne'r-do-well managed to infect the server which provides that app with a mining program called Cryptonight which enlists your browser into mining XMR coins.  For now your best bet is to uninstall that application if you have it installed; it has been removed from Google Play if you do not.  The Register has a bit more information on Cryptonight as well as some history on similar browser miners here.

"Another Chrome extension has been found secretly harboring a cryptocurrency miner – and it appears this issue is going to get worse before it gets better."

Today's shocking news; GPU vendors like the current mining trend

Subject: General Tech | October 19, 2017 - 01:26 PM |
Tagged: cryptocurrency, mining, gpu

At least some people are happy about the current GPU market and the effect cryptocurrency mining is having on it.  Indeed from the profit reports DigiTimes mentions, GPU vendors are making better profits from the current craze than the miners are, with all major vendors seeing major boosts to revenues.  This is good news for the average enthusiast as these vendors plan to ramp up their stocks and have greatly increased the amount of product they are ordering from NVIDIA and AMD.  It will take some time to fulfill these orders and you can expect the current memory shortage to have a minor effect on availability and price as well.  If supply can finally start to meet demand, we may soon see prices creep back towards MSRP.

"Gigabyte Technology and Micro-Star International (MSI), TUL, Colorful and Galaxy Microsystems have all been aggressive about the cryptocurrency opportunity since the mining trend emerged, and they have seen dramatic growths in related businesses. Asustek only started to see benefits from the segmnet in the third quarter."

Colorful Reveals Custom Eight Slot Motherboard For Cryptocurrency Miners

Subject: General Tech, Motherboards | September 14, 2017 - 02:13 AM |
Tagged: password cracking, mining, gpgpu, cryptocurrency, colorful, ai

Colorful recently unveiled an interesting bare-bones motherboard focused on cryptocurrency miners and other GPU heavy workloads with its main feature being eight double spaced PCI-E 3.0 x16 slots. The non-standard form factor Colorful C.B250A-BTC PLUS V20 motherboard measures 485mm x 195mm (approx. 19.1 x 7.7 inches) and offers a no-frills setup that is ready for miners to attach to open racks. The motherboard is based on Intel’s LGA 1151 socket and B250 chipset.

The majority of the board is taken up by eight PCI-E 3.0 x16 slots where the top slot is wired directly to the CPU and is electrically x16 while the rest are wired to the B250 chipset and are x1 slots. There are 16(!) PCI-E power connectors (eight 6-pin and eight 8-pin) for providing power to the GPU and two 4-pin ATX power connectors for powering the CPU and single SO-DIMM slot through what looks to be six power phases. Notably, there is no 24-pin power connector on this board to make it easier to use multiple power supplies and share motherboards between power supplies (though it’s not clear how Colorful plans to control turning all these power supplies on/off at the same time). Beyond the PCI-E slots there is not much to this motherboard. Internal I/O includes the 1151 socket for Skylake and Kaby Lake CPUs, a single DDR4 SO-DIMM slot, one SATA port, one M.2 slot, and six fan headers. Around back are two USB ports, one HDMI video output, and a single gigabit ethernet port.

The board is a no-frills design that should be quite appealing for miners but also as an easy way to jump into GPGPU projects (AI research, rendering, machine learning, password cracking, etc.). The 2-slot spacing allows air cooled (hopefully blower style) cards to be installed without needing to find and test quality PCI-E riser cables. There is no word on pricing yet, and while it should be on the cheaper side based on the features and hardware it’s packing as it’s a custom design aimed at mining it may actually come out at a hefty premium for the convenience it offers them. On the bright side, it might have decent resale value to factor into the ROI calculations for the other non-mining applications I mentioned (a mean password cracking rig!). A neat board in any case, and as I mentioned previously it is interesting to see the new designs and configurations the mining craze has enticed manufacturers into exploring.

Asus Launches B250 Expert Mining Motherboard With 19 PCI-E Slots

Subject: Motherboards | August 24, 2017 - 12:30 AM |
Tagged: mining, LGA 1151, Intel, cryptocurrency, b250, asus

Asus recently took the wraps off of a monster ATX form factor motherboard aimed squarely at crypto currency miners. The aptly named Asus B250 Expert Mining motherboard is based on Intel's B250 chipset and features an impressive 19 PCI-E slots! The board is based around Intel's budget chipset and is paired with an LGA 1151 socket for Intel Skylake or Kaby Lake CPUs. There are also two DDR4 memory slots and four SATA 6 Gbps ports.

The B250 Expert Mining motherboard is powered by a single 8-pin CPU power connector driving a 6-phase DIGI+ VRM, three (!) 24-pin ATX12V connectors, and three Molex power connectors. The top 24-pin drives the first seven PCI-E slots (including the single PCI-E x16 slot) while the other two 24-pin connectors are responsible for powering 6 of the remaining PCI-E x1 slots each.

Asus claims that the upcoming motherboard has several mining focused features including a tuned BIOS tweaked to improve mining efficiency, a splash screen at startup that shows the state of each PCI-E slot at-a-glance at each boot (Asus Mining Expert software) as well as voltage stabilization capacitors for each GPU slot.

With this motherboard miners will be able to hook up to 19 graphics cards to each motherboard which reduces the number of complete systems they need to build and maintain improving ROI time, increasing power efficiency, and reducing maintenance costs. At the time of writing there is a bit of hiccup with this plan though as miners will not be able to fully take advantage of all 19 slots for graphics cards. First off, miners will have to use Linux and even then they will be limited to a maximum of eight graphics cards from AMD and eight graphics cards from NVIDIA (if they can even get that working reliably...). Not all hope for an uber mining motherboard is lost though as Anandtech reports that AMD is working on a driver update slated for release later this year that will enable miners to use all 19 slots for their graphics cards.

Asus has not yet released pricing, but I would expect it to come at a hefty premium considering it offers the highest number of PCI-E slots on a standard motherboard so far. Asus has reportedly already begun sampling the B250 Expert Mining board to partners and it should be available at retail soon.

Even if you are not into the crypto currency mining scene, it is intriguing seeing the response to miners from the hardware manufacturers with new focused product lines.

Overview

There has been a lot of news lately about the release of Cryptocurrency-specific graphics cards from both NVIDIA and AMD add-in board partners. While we covered the currently cryptomining phenomenon in an earlier article, today we are taking a look at one of these cards geared towards miners.

IMG_4681.JPG

It's worth noting that I purchased this card myself from Newegg, and neither AMD or Sapphire are involved in this article. I saw this card pop up on Newegg a few days ago, and my curiosity got the best of me.

There has been a lot of speculation, and little official information from vendors about what these mining cards will actually entail.

From the outward appearance, it is virtually impossible to distinguish this "new" RX 470 from the previous Sapphire Nitro+ RX 470, besides the lack of additional display outputs beyond the DVI connection. Even the branding and labels on the card identify it as a Nitro+ RX 470.

In order to test the hashing rates of this GPU, we are using Claymore's Dual Miner Version 9.6 (mining Ethereum only) against a reference design RX 470, also from Sapphire.

IMG_4684.JPG

On the reference RX 470 out of the box, we hit rates of about 21.8 MH/s while mining Ethereum. 

Once we moved to the Sapphire mining card, we move up to at least 24 MH/s from the start.
