It might need a minor tweak to report all local gridseed properly, but gridseed actual performance gets properly reported the third value that takes into account the rejects and HW errors. Looking at the side of the PCB where the voltage regulators are placed, thanks to the heat sink we gridseed placed directly on the three VRMs their temperature is mining Ok, but there blade other mining that might have some issues with heat. A new circumstance can come up in which altcoins are utilized to cover electricity fees although Bitcoin is constantly and concurrently becoming mined. In fact they are not capable of supporting the power consumption that the GC chips would require if they are used in BTC mining crypto, so that is why Gridseed does advertise the new miners only as Scrypt capable and warns users not to try to mine BTC with them. We do recommend extreme blade when voltmodding the G-Blades as they are already pushed pretty close to their maximum by Gridseed and you do not blog a lot of headroom for further gaining some gridseed performance. We have found out mining setting the worker difficulty to or crypto not using auto switching does provide better results and blog stales higher efficiency and you can easily compare the number of stale shares to the 5-chip miner crypto the chip one and see that for blog. We also expanded the tests to cover various usage scenarios to check blade hashrate you can expect to get if mining for a fixed higher difficulty coin such blade LTC as well as if you are mining in auto blog switching mining to mine crypto most profitable crypto coin.

Unfortunately the new Gridseed Blade miners do not handle that well the MHz and started producing a bit more than the desirable number of HW errors. If you missed your possibility to participate in the photo contest, then however you actually missed a excellent opportunity to show some intriguing suggestions and win a five-chip Gridseed ASIC miner as this was our last week of the four week photo contest. There is a new cgminer 4. A bit of a disappointment as we got just about 4 MHs total performance from the two PCBs with 40 chips each that combined make the 80 chip Blade Miner.

It is placed on the back side of the PCB where the voltage regulators are and it helps to reduce their temperature, because the airflow from the cooling fan does pass through it as well and helps to keep it quite cool.

This should be easily fixable with an update on the software miner code in order to properly report mining local hashrate based on blade number of chips for each of blog PCBs in gridseed Gridseed Blade Miner. We went down to MHz just to check that with it we are actually getting around Again we advise anyone willing to do a voltage modification to his Gridseed G-Blade ASIC miner to be extra crypto as these devices are more expensive and can handle less abuse from the users as compared to the smaller 5-chip ASIC miners, blog proceed with caution!

Gridseed chip Blade Miner - Crypto Mining Blog
And while they still do seem to work fine in the long run this may cause some issues, so you might consider replacing the capacitor with a more serious one. Again we are going to advise you to be very careful should you consider doing a voltage modification to the new Gridseed G-Blade miners as it can be dangerous and you can easily damage your expensive miner. The modification here is not as easy as just replacing one resistor as you need to do cooling improvements as well and you are not able to push things too much to be on the safe side, so the hashrate increase is also not that big as compared to what you are getting without the modification.
So you might really want to reconsider if it is worth doing the modification at all, we are probably not going to be modding another G-Blade for a while until we see how the voltage mod will handle on the longer run in its current state. In the previous post with our first hands on experience with the new G-Blade miners we have mentioned a bit the topic about voltmodding the new Blade Miners. Now is the time to talk a bit more about it and share our experience based on the voltmod experiments we have already done on our G-Blade.
So it is easy to do the voltage modification to the G-Blade as you are going to be essentially replacing the same resistor, though there is a bit of a difference in how things look on the new PCB.
There are no element markings, so make sure you replace the right resistor marked on the photo above with a green circle with the written on it. Do not be in a hurry to solder a new one before reading our advice. Since the default voltage of the GC chips is 1. Also since the voltage regulators used on the new G-Blade are not that much powerful than the ones used in the 5-chip models you are not going to have the same safe headroom to increase the operating voltage of the chips, in fact you are actually pretty limited.
We were quite disappointed in how Gridseed has designed the cooling of the new G-Blade miners, and especially the use of a powerful and noisy fan to compensate for the lack of adequate cooling for the three VRMs.
The CG chips can easily be cooled with a silent and much lower RPM fan, however it seems that the powerful fan is there just to be able to ensure that the mosfets are kept cooler without having any radiators directly placed on them or on the back of the PCB where they are located.
We are getting about 60 degrees temperatures of the IR mosfets at the standard voltage and operating frequency of MHz, however as soon as we remove the fan the temperature of the VRMs starts to get higher very quickly while the CG chips still remain pretty cool.
By replacing the resistor marked above with a higher value one and increasing the operating voltage of the chips you can easily overload the voltage regulators and burn them in a matter of just a second without the fan and even with the fan running you can still burn them if they get too hot.
So the moment you decide to voltmod the new Gridseed G-Blade you need to also think of improving the cooling of the voltage regulators a lot and not try to push the operating voltage of the chips too much, or you risk the VRMs easily overheating and burning up.
We have used an old motherboard chipset radiator glued on the back of the PCB with thermal glue where the voltage regulators are placed, so that it can help in keeping them cool and have also placed a smaller video memory cooler directly on top of the regulators on the other side of the PCB. We have slowly started increasing the operating voltage of the chips from the standard value of about 1.
Need help setting up a batch file for windows mining? I am not sure if anyone has posted a guide but I couldn't find one put together, so here is what I did to get my miner up and running. First, I received the Gridseed Blade 5. Once that was done, I now had to decide how I was going to run the miner. I created a bat script using notepad to pass the parameters for my miner which looked like:. When I ran it initially, my asic mining hardware wasn't detected.
So, I killed cgminer, and ran Zadig. With the 39 kOhm resistor replacing the standard 33 kOhm one we already saw the mosfets easily getting up to degrees Celsius in about a minute without the extra cooling.
With our extra 2 radiators attached to the PCB and the chips we were able to bring the temperature below degrees on the long run, so pretty much safe for leaving the miners run all the time like that, though you should continue to carefully monitor the temperatures.
We have decided to stay at 39 kOhm, though pushing a bit more for like kOhm with extra cooling might work, going for 47 or 49 kOhm may be a bit too much for the VRMs to handle. So be extra careful should you decide to go higher tan what we have used, though we do not recommend it, and monitor carefully the temperature of the voltage regulators as they may get very hot in no time and burn up without adequate cooling!
Here is what we are getting after replacing the resistor from the standard value of 33 kOhm to a 39 kOhm one. Running the device only one of the PCBs is connected on the photo at MHz seemed quite Ok with little HW errors, though we have decided to go a step lower in order to lower the HW errors a bit more.
After some additional testing we have settled for MHz as it brings down the HW errors up to something about per hour which is much more acceptable than getting an error about every minute or so at MHz.
The power usage per PCB after the voltage modification is about 85W or a total power consumption of about W for the whole modified miner. The results we are getting are not bad, but do require you not only to solder a resistor, but also to improve cooling of the device. You also need to be extra careful should you decide do go even higher than what we have achieved as the voltage regulators might not be able to handle well the additional load or the temperature.
It seems that with the G-Blades things were already pushed close to their limits by Gridseed, so there is not that much of headroom left for users to squeeze some extra performance for free by voltmodding the units. We are a bit disappointed by that, we kind of expected more, especially after seeing what the GC chips were capable of in the smaller 5-chip devices. We are going to be doing some more tests and experiments in the next few days to see if we can get something better than what we are already getting, but the chances for some significant improvement are not that good.
Again we advise anyone willing to do a voltage modification to his Gridseed G-Blade ASIC miner to be extra careful as these devices are more expensive and can handle less abuse from the users as compared to the smaller 5-chip ASIC miners, so proceed with caution! The smaller 5-chip miners allowed more headroom as they were designed to handle much higher power usage because of the BTC mining part, but for the new G-Blade miners Gridseed has decided not to support the SHA mining part the chips do, but the device cannot supply enough power, so do not try to activate BTC mining or your miner may burn.
So the headroom for overclocking without doing some modification related to the voltage regulators is actually very little with the new G-Blade ASIC devices, and working only on improving their cooling does help only a bit. Reworking the power part of the miner could open up some additional possibilities, but that is not something that most users can easily do themselves unlike the replacement of a single resistor for example.
In short, if you are expecting performance boost on the bigger G-Blades like on the smaller 5-chip devices with a voltmod, you will be very disappointed, and the fact that after voltmodding the Blade Miner you might have trouble cooling it down properly for long term operation might not be worth the extra performance boost you will get. We just got our unit yesterday and have been playing with it since, so we are ready to share our first hands on experience with the new G-Blades.
Starting with our first impressions, the new G-Blade Miner is a bit smaller than we have expected it to be, but that is not a problem. The thing that we did not like very much is the noisy fan — a 92mm fan is being used and a quite powerful one that can produce up to about 55 dB.
