Wait... if I understand this right. $600 for 24Gh/s? What...?

Correct, but I haven't actually seen anywhere to buy one since I completed the review.

Well, that sucks that wasn't actually Biostar responding to this thread. I am still not affiliated with either Biostar the company, or Biostar the scammer. I was asked to do this review by a friend who runs a hardware review website and was offered a BTC-24GH unit to review from Biostar, which is one of his regular review partners. I posted it here for the community to learn about the device. I hope it was a helpful review for those that heard about the device and wanted to learn more information about it. Let's hope the real Biostar sees our feedback and makes a better device the next time around.

Woops, I meant to add the price and forgot. I have updated the post with price.

tl;dr = $599.99

For those wondering, I am an independent hardware reviewer and not affiliated with Biostar in any way.

It's great to see Biostar responding to feedback in this thread. My hope is that they take our feedback and make something that puts all the pre-order ASIC manufacturers to shame.

They have the technology. They can rebuilt it. Smiley

Yeah, after I read the power readings and did the math it was quickly apparent that it was not what it was hoped to be. Hopefully Biostar can take the constructive criticism and make a better product for round 2.

Biostar BTC-24GH Bitcoin Miner Review

The BTC-24GH is Biostar’s first venture into the ASIC market, after already releasing special motherboards for GPU based mining. The BTC24-GH is a 24 GH/s device, or GigaHashes per second. This puts them in about the middle of the pack as compared to some other ASIC manufacturers with regards to their hashing power and their price.

About the Reviewer

I have been Bitcoin mining for about a year on and off with a Butterfly Labs Jalapeno, and some powerful GPUs before that. The speed of my Jalapeno and the speed of the BTC-24GH differ by about 17GH/s, but there are a good deal of other factors to compare such as ease of use, efficiency, and time to break even on the purchase that will be the deciding factor in my review of the BTC-24GH. In any case, it’s exciting to see a major hardware manufacturer like Biostar getting on board with creating some Bitcoin hardware.

About Biostar

Biostar, Biostar Microtech International Corp, is a Taiwan based motherboard manufacturer founded in 1986. Biostar, an ISO 9001 certified manufacturer, and is probably most well known for their motherboards, but have also branched out into designing and manufacturing other computer hardware such as video cards, barebones computers and industrial computers. They were actually the first GPU manufacturer to allow users to modify the voltages and frequencies to overclock their cards. Biostar has the manufacturing capabilities to take Bitcoin mining to the next level much faster than any other ASIC manufacturer out there, especially if they introduce overclocking to the hardware capabilities. We will have to see how their devices progress over time. Proclockers has been given a chance to review their first ASIC device, the Biostar BTC-24GH.

Biostar’s Take on the BTC-24GH

The "BTC-24GH", with 64 ASICs on-board that offers 24GH/s performance which is equivalent to more than 30 ATI 7970 graphic cards. ASIC mining solutions are good at solving mathematical hash functions; and their strong hashing power and low power usage, making it very efficient to use.

Packaging

The packaging of the BTC-24GH is very similar to how you would receive a Biostar motherboard. It even has the familiar sticker with the specifications on the side of the box. The box is just a bit smaller, perhaps the size of a Micro-ATX board or similar form factor. The board was fairly well padded with a static resistant bubble wrap bag inside the box. The special USB 2.0 connector that connects to the USB to COM adapter for the BTC-24GH board comes in it’s own small sealed static resistance bag.





Features and Specifications
24 GH/s (+/-10%)
130 W (+/-10%)
Interface by COM to USB 2.0 Cable
Flexible Mining System can stack up to 50 Board totaling 1200 GH/s hashing power.
64 ASIC mining chips per board.
Dimensions: 244x244 mm

System Requirements
Efficient, external cooling system
External 24 pin power supply with additional 4 pin.
USB 2.0 connection
Supported OS: Windows 7 or Windows 8
Motherboard standoffs (Suggested 5 cm)

Packing List
1x BTC-24GH
1x Power cable (board to board)
1x Quick Installation Guide
1x COM to COM cable (board to board)
1x USB to COM cable (PC to board)
1x Setup DVD

Please Note: The COM to COM cable and USB to COM cable will be connected in the package. Make sure to check that the pinouts match those in the following photo, or your miner will not start. I ran into this issue out of the box, which is a big factor in my overall rating of this product.

A Closer Look at the BTC-24GH

Here we take a closer look at the hardware for the Biostar BTC-24GH.








Configuring the Mining Software

The BTC-24GH comes with a special mining software called BMminer. The BMminer software can only be used on Windows, sorry Mac and Linux users. Hopefully they release drivers and software for each major OS, as many serious Bitcoin miners run Linux. The BMiner software was included in the setup program included on the DVD. It allows you to take screenshots of your current speed and that is about it. I could not find a log of any sort, which is lacking compared to the freely available CGMiner, BGMiner, and other open source mining software available. The fact that you must use BMminer to mine Bitcoin with the BTC-24GH is limiting it’s audience, as CGMiner, BMiner, and other applications run in Windows, Linux, and Mac.

Adding the COM to USB Driver

The manual suggests that you run the installation of the COM to USB driver as an Administrator. The screenshots in instruction manual do not really follow the software that was included. It shows that there is an actual driver file that you need to install, but you can actually just run the setup.exe that is included on the DVD now instead. I am guessing that the DVD was updated after the manual was printed, which is understandable with brand new hardware. It would be great if they could update their online PDF though.



Installing the Software

As I mentioned previously, the BTC-24GH has a proprietary mining application that is required to currently mine for Bitcoins. The mining software requires Microsoft Windows to install and run your BTC-24GH ASIC miner. The instructions for installing the mining software are fairly vague in the instruction manual. In fact, most of the instructions in the manual were fairly vague in general. They are actually wrong, as the whole software installation can now be done, from what I can tell, through a much easier setup application than what is actually described in the manual.

Editing the Mining Config

The manual said to start the install as Administrator, but apparently you cannot edit the Mining Config files directly in the mining software from what I found, even if you launch the mining software as Administrator. I ended up just starting up Notepad as Administrator to edit the files manually. The software updates immediately with the values that are saved.

The previous install process installed the mining software on my Desktop in:

C:\Users\Public\Desktop\BMminer.

You can find the mining worker config to edit in the C:\Users\Public\Desktop\BMminer\apps\miner\save\worker.txt file in that directory.

Testing - Let’s Start Mining

After fixing a fairly major oversight in regards to the manufacturer’s pre-assembled COM to USB adapter, and configure the mining software, I was able to finally start mining. The pinout was backwards from the factory, which is an honest mistake, but not something that I was expecting on a review unit. Once I switched the pinout, all LEDs lit up properly as per the instruction manual, the mining software started recognizing the chips, and we were registering shares on BTC Guild.

While the mining software runs, it appears on the screen in various background colors depending on what I can tell to maybe be the heat of the board. I’ve taken some important readings during operation that have opened up some new issues about the BTC-24GH’s operation. While the temperature of the board ran within it’s thermal range nicely, the Wattage readings were giving me some concern.

I ran the system for around 7 days, but on day 5 I had to power it down for a major electrical storm in my area. After initial burn in testing for a few days, I finally set up both of my Kill-a-Watt wattage readers to get some actual wattage specs. I was kind of shocked at how many total watts it was using even idle. It quickly became apparent that this device needed quite a lot of power once it actually started mining. The total was approximately 278 Watts including the external fan and the mining computer I have tweaked to be very low power usage at only 67W average. The BTC-24GH ASIC device itself failed to meet it’s own power variance of 10% by an additional 30W. That means the BTC-24GH is actually 173W, almost 25% over the advertised power rating of 130W, or even close to the 146W variance. One of the biggest factors in Bitcoin mining is the cost per MegaHash or GigaHash to actually mine the Bitcoin. The BTC-24GH has a 76.98 MH/s/W efficiency rating. The Butterfly Labs Jalapeno I own gets a 205.71 MH/s/W efficiency rating. The BTC-24GH device fails to meet it’s own factory specifications for it’s power usage and fails to receive a passing grade for MH/s/W, the standard in Bitcoin power usage.



Another important factor in Bitcoin mining is the actual overall SHA-256 hashing speed of the device. The speed of the BTC-24GH is a bit confusing, as it has 2 different hashing speeds displayed in the mining software at all times. One is System Speed, and the other is Share Speed. The Share Speed is consistently lower than the System Speed by about 1 GH/s, and the reported speed on BTC Guild is around another 1 GH/s lower than that. When I have used a Butterfly Labs Jalapeno, I had much less variance between what CGMiner, an open source virtual currency mining software, reported and what was being reported on BTC Guild’s charts.




When it comes down to it, the most important factor of mining Bitcoins is the overall cost of the mining hardware vs. it’s potential earnings. As of right now, 1 Bitcoin is equal to approx. $574. With a hefty 278W power usage and a 21.34 GH/s the BTC-24GH I am losing $0.24/day at the default kWh rate.  Source: http://www.bitcoinx.com/profit

Comparison With Other ASICs

The BTC-24GH was quite a bit more work to get setup and start mining than the Butterfly Labs Jalapeno I purchased last year, but is quite a bit faster by design. Once I got the pinout issue figured out was fairly simple to get the hardware setup. The Jalapeno was essentially a plug and play unit, and did not require external cooling, or an external PSU. The BTC-24GH has “some assembly required” to get your miner running. You may even have to purchase an ATX power supply to run it if you don’t have a spare. This will definitely be a deterrent for some Bitcoin miners, as the ease of use of some of the newer ASIC devices on the market is quite noticeable. I believe the intention for the BTC-24GH is to appeal to hardcore modders like our audience here at ProClockers, but I’m not sure what the warranty is on this device, or the warranty implications for trying to overclock it. Biostar has always been a friend of the overclocking community, so possibly some day we will see either factory overclocked or the ability to customize your own overclocked ASIC chip settings out of the box. That would be a game changer..  

Conclusion

Overall I think that Biostar is a little late to the punch with the BTC-24GH, but I’m definitely not counting them out of the later rounds due to their manufacturing capabilities. It’s a little bit slower than I would like to see from a new ASIC unit at this point in the bout, but many other manufacturers have sold out of all of their original units. If Biostar can come down in price a little on these boards and include some additional hardware like the standoffs, the BTC-24GH could sell well to Bitcoin enthusiasts chomping at the bit to get new hardware.

Many of the ASIC manufacturers on the market also today take pre-orders for devices that don’t ship for months, or never ship. In many cases those orders that do eventually ship have been delayed multiple times before they are eventually delivered. During that time, the miner loses out on a serious amount of profit from their mining venture, especially if they purchased the device with Bitcoin. This is where Biostar can make up some serious ground on the competition. If they can beat the major ASIC manufacturers to market with the next big Bitcoin ASIC technology, and maybe even find a way to accept Bitcoin for their devices directly, then it will be a good day for Bitcoin miners everywhere. No more waiting for pre-orders and losing out on the Bitcoin gold rush.

I think that Biostar has done just the right thing by providing these devices for review. Designing and manufacturing Bitcoin mining hardware is a new venture for them, so these reviews should provide them with some excellent feedback from miners like myself that will help them make more competitive devices in the future. Watching major hardware manufacturers enter the game is exciting to say the least. Biostar could very well use the feedback from these reviews to create the next great advancement in ASIC technology, and I think at a much more affordable price than it’s competitors due to it’s manufacturing capabilities. While the BTC-24GH might not be the best ASIC on the market, the next Bitcoin ASIC from Biostar could be a serious contender in the ASIC marketplace.

Vircurvault Bitcoin Wallets are now generated using the latest v2.8.1 source code from Bitaddress.org. Grin http://vircurvault.com

There are definitely some cool new features like better randomization in address generation and easy BIP38 password encryption that we wanted to take advantage of with our wallets as we move forward. We already have an Encrypted model that uses an intermediary key generated with the Casascius Bitcoin Address tool, but BIP38 might be something we can provide for all wallets at some point either with your password of choice, or generated randomly.

Thanks to all who have supported Vircurvault so far! We are continuing to seek out better storage solutions for our Vircurvault wallets as Bitcoin technologies advance. We will continue to support more coins as they become viable, new technologies that support security, and new designs are popping up as they become available from our designer.

Thanks again,

Vircurvault

Vircurvault is a heavy duty laminated virtual currency paper wallet first designed for Bitcoin, but since the popularity of altcoins has grown so much, we have started offering altcoin wallet designs as well.

We have not had one single complaint so far from any customers, and we are adding new designs often. Each design will eventually be available for each coin we offer, but we are still working on getting each variation ready.

We currently offer Vircurvault wallets payable in Bitcoin or Litecoin, but we may offer additional payment methods for other altcoins in the future such as Dogecoin or other popular virtual currencies. Prices are subject to change as we continue to figure out our overall cost of making the wallets and our time involved with making them.

We currently have original Litecoin and Dogecoin wallet designs available, but can offer any of the current Bitcoin paper wallet designs to be ported to those coins as well. We just haven't had time to put together the website graphics and such yet. 2 new Dogecoin wallet designs, along with a freebie wallet design for all coins available soon!

Altcoin Wallets Available

Litecoin Silver

Dogecoin Greyhound

Please let us know if you have an altcoin that you would like to see as a Vircurvault, along with any color or design ideas. We also offer bulk pricing on orders over 15 wallets.

Thanks!

Use a paper wallet like Vircurvault and keep your coins safe from douche bags!

That was the purpose of it in the first place after Instawallet was hacked. That incident in itself was the original precursor to the Vircurvault wallet being designed.

I know some of you are going to be instantly turned away thinking, "Why would I ever trust this guy with my private key?". I can assure you that I do not try to memorize the private keys, nor do I make any additional copies, unless specifically requested by the customer.

That doesn't help.

STFU TF!!!  Angry

Outrageous quote coming from the guy who lost how many million dollars in Bitcoins*, right? I realized it was him that posted on my thread soon after the incident and I was editing my main post one night. I just thought it was some douche bag at first, and it turned out it was.

We shipped our First Litecoin wallet this week. Don't forget that all wallets are now available on our website for Bitcoin and Litecoin. We are also in the process of creating wallet designs for many other popular alternative coins. if you have a suggestion that you are interested in, let me know.

Make sure to check out our new designs and colors, especially some new colors for the ladies of Bitcoin out there, Pink and Violet. We thought they could be a great gift for Valentine's day to show your significant other that there is a physical side to Bitcoin. It's not all made up digital hashes. Good luck explaining that one anyway. Smiley

PM me for color or coin suggestions.

Thanks to all who have supported Vircurvault so far!

All wallets are handmade in the USA.

I have been constantly stress testing the first ever made Vircurvault Bitcoin wallet that I printed out and pressed on my laminating machine for testing. So far it has been in my wallet in a credit card slot since that day. I pull it out often these days to show people and try to explain what Bitcoin is. Some conversations are better than others...

I don't have much on the test wallet, like 2 faucet payments to make sure it's "live", so I have been trying to push it to the limits on each test. It is afterall my first Vircurvault wallet off the presses, so I'm not holding back anything. I can always print another one Smiley My main goal with this project is to provide a simple, yet high quality product for storing your virtual coins.

I know that my test wallet is waterproof, as I had tested that in my initial Vicurvault stress tests, but I did not think until today to test if floats in water. After several tests in the bathroom sink this evening, I can verify that the same test wallet officially floats! I believe that means the Vircurvault is the first, fully water friendly Bitcoin wallet! Ahoy, me maties!  Grin

Given the surge in altcoin activity this week, we have decided to start making wallet designs for other coins. Litecoin will be our first alternative virtual currency wallet that will be available, followed by a handful of others once designs are completed. The Litecoin address generator will be based off of the Liteaddress.org source code with modifications only to the layout of the HTML for printing our designs.

We have already found generators for PPCoin, Feathercoin, Terracoin, PrimeCoin, Freicoin, FrankoCoin, AnonCoin, BBQCoin, Worldcoin, and Devcoin Smiley If you know of one I am missing, please let me know and I will add it to our wallet generator library. We will make it available for purchase right after the design is converted to the generator format.

It would be great to see generators for every coin available. I would love to provide wallets for Namecoin, Megacoin, and a few others if someone can figure out the JS part.

I have most of the wallet generators setup printing at this piont, but I am waiting on new designs from my designer for each wallet.

Stay tuned for paper wallets designs for many alt coins, as well as new Bitcoin designs coming soon Cheesy

I'm not a fan of pre-orders, so I will hold off on creating products to purchase until they are actually available. Litecoin wallets are coming first!

I think a very useful feature would be to be able to set the datadir in the client on install. I think it's a major oversight that each blockchain is stored in %appdata. I just moved mine last night by setting a variable in my bitcoin.conf file, which freed up 13.3GB on my C: drive. Using a SSD for my main drive, that is a fairly large chunk of it for just Bitcoin.
