The Scrypt cloud mining service Scryptcc was one of the first to start offering Scrypt cloud hashrate using GPUs for mining alternative Scrypt-based crypto currencies and paying its users in Bitcoin. The service was quite interesting when they’ve launched, but had some issues from the start and they were a bit slow in fixing things, but lately they seem to have improved. In fact we’ve seen some similar services come and go and this one is still here and without having some major hiccups like others had. The interesting thing was that up until recently they were still using only GPUs for mining Scrypt and thus the profitability was not good at all. However there is a new announcement that they have started adding Scrypt ASICs in their new data center and report that profitability has started to get better again. Currently the price of 1 KHS is ~0.000324 BTC or about 0.324 BTC per Megahash worth of Scrypt mining hashrate at the service, so definitely not the best price. According to the profit calculator available on their website buying 1 MHS of cloud mining hashrate at the moment you can expect to break even in about 152 days. This is not the best deal we’ve seen for sure, but not the worst either.

The new fork of bfgminer with support for ZeusMiner’s Scrypt ASICs (Litecointalk development topic) that we have told you about a few days ago is seeing some nice development. The fork that is compatible with ZeusMiner, GAWMiners and Hashra Zeus-based Scrypt ASICs has been updated to bfgminer 4.2.1 and the driver has been reworked a bit including some changes to the command line options that are no longer the same as the initial cgminer release with support for ZeusMiner ASICs.
The latest release even has an option to “override” the maximum frequency of 382 MHz that the ZeusMiner ASICs are apparently limited to, however this only overrides the software check, but does not actually make the miner work at higher frequency (the 382 MHz maximum might be a hardware limitation). Also do note that there might be some issues running multiple miners in a single instance, so you might need to run 5 or more units in a single miner per instance of bfgminer configuration.
Below you can find a windows binary of the bfgminer 4.2.1 that you can try, just make sure to set the right number of chips depending on your miner model as well as the virtual COM port at which the miner is detected. The recommended operating frequency still seems to be 328 MHz for most people as a good balance in terms of performance and HW error rate, though you are welcome to play with it.

The ZeusMiner Blizzard Scrypt ASIC also available as the GAWMiners Fury is a nice little device that comes at a really attractive price for the hashrate it offers. They are the ideal choice for smaller miners that want to get a Scrypt ASIC miner, but don’t want to spend too much for it… and quite a lot of people like that already have purchased these devices. Being so attractive with their current prices and performance of about 1.3-1.4 MHS it is no wonder people are also interested in modifying them for even higher performance. The simpler thing that you could do is to try to improve the cooling with the addition of some heatsinks directly on top of the 6 ASIC chips to get a little more headroom for increasing the operating frequency with lower number of HW errors. The more complex thing is to try to do a voltage modification in order to allow for the chips to have no trouble operating at higher frequency.
People that have used or still use the smaller 5-chip Gridseed Scrypt ASICs and have done a voltage modification to them knwo that these small miners were able to handle a significant performance increase without trouble. The reason for that was the fact they they were originally designed to be used for mining both LTC and BTC, thus they could handle higher voltage and operating infrequence easily if you only used them for Scrypt mining. The case with the ZeusMiners however is not the same, it seems that their miners are already pushed quite high in terms of power usage and operating frequency not leaving you with much headroom for experimenting. Voltage modification of a ZeusMiner Blizzard or GAWMiners Fury is possible and can be done with the replacement of resistors just like on the Gridseed ASICs, however the advantage you can get in terms of hashrate increase is not going to be that attractive so that a lot of people would be willing to do it. There is a topic on the Bitcointalk forum where people are trying to modify their devices and are reporting some useful information and their experience and results, so you might want to check that out if you are interested.
