This week ASRock are launching a high/low combination of motherboards for Haswell.  The first one is going to be one of the wildest designs on the Z87 platform, using an LSI 3008 chip combined with a 3X24R expander to provide sixteen SAS-3/SATA 6 Gbps alongside the six SATA 6 Gbps ports already provided by the chipset, giving 22 total.  We actually saw this motherboard at Computex earlier in the year, all hooked up:

At the time, we postulated on the PCIe lane allocation, as ASRock had said that this was possible with only one PLX 8747 switch, whereas on the Z77 Extreme11 they had used two.  It all comes down to the LSI 3008, which requires eight PCIe lanes by itself.  Since that iteration, ASRock have also added Thunderbolt 2 into the mix, using a controller that requires 4 PCIe lanes to give two TB2 ports.  This also goes along with four-way SLI and Crossfire, suggesting that using switches they are able to supply x8/x8/x8/x8 to the GPUs, another x8 to the LSI chip and x4 to the TB2 controller.  Without getting the board on hand, I would assume that the motherboard disables part of the PCIe slots in order to use Thunderbolt 2.

The Z87 Extreme11/ac also comes with dual band 2x2:2 802.11ac (ASRock tend to use the Broadcom controller), a Wi-SD box to improve wireless range (also provides four front panel USB 3.0 ports and an SD card reader) and Purity Sound, ASRock’s name for their Realtek ALC1150 audio codec solution.  Given the image above, we also see a total of 12 USB 3.0 ports, dual NICs (Intel), two mSATA ports (shared with chipset SATA ports) and an eSATA port.

Pricing has not yet been announced, but the previous Z77 Extreme11 was $600.  That had two PLX 8747 chips whereas this only has one, but there is TB2, extra USB 3.0 controllers, dual NICs and dual band 802.11ac WiFi, so I would hazard a guess that it might be in that $400-$600 price range.

The other board coming out of ASRock is somewhat aptly timed.  Bitcoin and Cryptocurrencies have been up and down in the news this past year, and even today Bitcoin has hit $660 with Litecoin going above $8.50.  Back around the Bitcoin blowout earlier this year, I pitched around the idea of a motherboard built with cryptocurrency mining in mind.  ASRock responded in kind, with the H81 Pro BTC and H61 Pro BTC:

The idea behind these boards is simple: a very cheap motherboard with a cheap dual core CPU and minimal power delivery, the board is designed to accommodate multiple graphics cards with x1 to x16 risers.  ASRock claims these boards are able to support six GPUs for mining.

There is one caveat though.  For Bitcoin, GPU mining is almost dead, offering little return unless the price of Bitcoin rises a lot.  This is due to the advent of ASICs that offer more mining capability for less power.  There is still money to be made from Litecoin, which is somewhat buffered by the ASIC revolution, although for my GPU collection I would currently be earning $10 a day (after electricity bills) for 2000W+ of GPU noise and heat.  Some might call the BTC boards a little too late, whereas due to the rises we are seeing today, that might not always be the case.  There might have been potential for these systems had ASRock supplied the system full of USB ports instead of the parallel/com/vga port combination as shown in the images above.

As always, despite what ASRock PR might have you believe, I would like to add a disclaimer: there is no guarantee that Bitcoin mining (via ASIC or GPU) will generate a financial return.  Only invest what you can afford to lose.

Nevertheless, I would hope that these motherboards would be sold in the $60 or below segment.  That seems awfully low for a motherboard, but therein defines the purpose of such a product in the cryptocurrency world.  The US Senate is expected to report on Virtual Currency today, which could explain the recent influx of investment into Bitcoin and Litecoin.

    Can I ask how can I boot up 22 HDDs using this board? Without no staggered spin-up, don't think a normal 600W PSU would be able to spin up all the HDDs at the same time. Reply

    Unless you have about 40 GPUs lying around, you're nowhere near earning $10/day from GPU mining. This is before factoring in the negative result from having paid for the electricity to run that many. GPUs have not been profitable for quite some time - the faster and more power hungry cards simply increase the speed at which money is lost. :) Reply

    June, some time ago was June. That's when it was no longer economically viable to GPU mine. It hasn't been reasonably profitable since April-May depending on what you pay for electricity. Reply

    With my cards, I can compute about 4000 MH/s on Litecoin. At today's difficulty (1320) and Price Per LTC ($9.50), that means about $28.80. Using 2500W at $0.17/kWh, this costs ~$10 in electricity a day, making overall gain at $15. Did you check today's BTC/LTC prices ? :D Reply

    *4000 KH/s. It is still profitable for Litecoin mining, BTC mining definitely not. Reply

    Why oh why have they put those tiny fans on the MB. Nothing is more anoying than the high pitched wine of a worn out MB fan. Reply

    Things have changed in recent generations. More often than not, they do not even turn on unless your ambient temperatures are very high. At least several boards I have had in recently to test have had this feature on their MB fans. Reply

    This article makes the hyper-mega RAM article look positively relevant to the average tech enthusiast. Reply

    i would love to know when the H81 Pro BTC and H61 Pro BTC are due to hit store shelves, but it seems like nobody has a release date yet...and the same goes for Biostar's H81S2 and H61B mining mobos... Reply
