The KnCminer Titan Scrypt ASIC is still probably the fastest and most power efficient miner for Scrypt coins out there, but at the same time it is also one of the most problematic one to use and run. There are hardware issues resulting in dying cores and problems with the DCDC power modules, the software is also far from perfect, even though there are modifications over the last official firmware such as GenTarkin’s Custom KNC Titan Scrypt ASIC Firmware, there is still more to be desired. One of the things that is quite annoying is that the Load Balance pool strategy in the official Firmware 2.0 for the Titan is not working, so you are essentially left only with the Failover option.

Even if you run just one Titan cube you are still getting quite significant hashrate and while this is fine if you are mining for high-difficulty coins such as Litecoin for example, it is not for low difficulty coins that may have just a couple of MHS total network hashrate. Throwing your full KnC Titan hashrate at a coin with low difficulty and total network hashrate will simply increase the difficulty in very short period of time (depending on the difficulty adjustment algorithm of the coin) making it pointless to be mined. What you would want to have for low difficulty Scrypt crypto coins is to be able to split your Titan hashrate between multiple cons on a single multipool or between multiple mining pools in order to maximize your mining profit without bumping the difficulty to a level making it unprofitable for a given coin to be mined.

GenTarkin’s custom firmware has implemented support for the alternative Balance strategy in the web interface, though it is essentially something supported by the bfgminer as an alternative to the Load Balance pool strategy. Considering that the Load Balance strategy is not working properly and you cannot dedicate lets say 10% to one coin, 30% for another and the remaining 60% to a third one, you might at least try the equal spreading of hshrate that the Balance strategy should provide. The Balance strategy should split the hashrate in equal parts between the multiple defined pools, so if you have 4 pools the total KnC Titan hashrate should be equally split between them with about 25% for each. The Balance pool strategy works just fine not only on the custom GenTarkin firmware, but also on the stock Titan 2.0 firmware as both rely on the bfgminer 5.1.0 and the miner provides the actual functionality, you just need to configure it.

{
"pools": [
{
"url": "hash-to-coins.com:4444",
"user": "titan.1",
"pass": "d=512"
},
{
"url": "hash-to-coins.com:4444",
"user": "titan.2",
"pass": "d=512"
},
{
"url": "hash-to-coins.com:4444",
"user": "titan.3",
"pass": "d=512"
},
{
"url": "hash-to-coins.com:4444",
"user": "titan.4",
"pass": "d=512"
}
],
"scrypt-n": 10,
"balance": true
}

With the stock firmware you will have to go to the Manual edit mode and edit the pool configuration file by hand, what you need to essentially do is add the option "balance": true at the end of the configuration file to tell bfgminer to use the Balance pool strategy. Above is an example configuration file with four different coins and Balance pool strategy that should equally split the total hashrate to about 25% for each of the coins. GenTakin’s latest custom firmware adds support for the Balance strategy in the Normal edit mode as well, making it a bit easier for users, but the end result is the same. As we have said already, the Balance pool strategy will work just fine with the latest official Titan 2.0 firmware, so you can try it even without a modified firmware. However custom firmwares such as GenTarkin’s add a lot of other and more useful features than just making some of the things that do not work properly in the official firmware more user friendly.

We were not among the ones to preorder the last ASIC mining hardware that KnCMiner has sold to users, the Titan, but recently we have obtained some KNC Titan Scrypt ASICs to play with. The first thing you will notice is that even the latest official firmware of the devices version 2.0 is still pretty basic and the hardware is buggy, especially the earlier batch 1 devices. So we started looking for an improved version of the original firmware that would allow us to get the best out of the KNC Titan Scrypt ASIC and we have ended up discovering GenTarkin’s Custom KNC Titan firmware.

This modified firmware provides users with an improved and more functional interface and more importantly a safer to use and capable of providing you with the optimal performance and power usage that your Titan cubes can provide you with. This of course comes at a price, you need to purchase a full license for the modified firmware that is currently sold at $75 USD for the controller and if you have an additional devices you can purchase extra licenses for $35 USD each for each controller (key for activation only), not for each cube. There are also additional discounts available for volume licensing for purchases of 10 or more licenses for large miners with more devices available.

We have just started using the latest version 1.0.2 of GenTarkin’s Custom KNC Titan Scrypt ASIC firmware on the hardware we have obtained and as you can see on the screenshot both cubes we have attached to the controller have some issues with some of the chip dies and DCDC power units. You can see the difference in how the advanced settings page looks like for both the stock and the custom firmware. The power usage for example on the custom firmware reports more accurate power usage numbers and when you take into account the power efficiency of the PSU you can get pretty accurate power consumption numbers for the actual power used at the wall. There are number of additional protection mechanisms built in as well as optimizations to help run your mining hardware stable and with less issues on the long run. The Energy Saver is also something new and very interesting feature that supposedly can help you find the optimal settings for each die and thus help you get lower power usage while retaining optimum performance.

We have just started using GenTarkin’s Custom KNC Titan firmware and so far we like the improvements and extra features we see from the latest stock firmware from KNC, in a few days we are going to be sharing more from our experience as well as doing a more detailed review. Meanwhile if you have some KNC Titan Scrypt ASIC miners and you are using the stock firmware you might be interested in checking out this custom firmware, especially if you are having some issues with your devices or have more than one miners.
