Cleaning up the entire thing effectively does need a long time and effort as due to the size of the crystals on the Jasminer X4 ASIC chips it is like cleaning 8 CPUs of computer systems. And you require to make certain you are cautious not harmful anything, though the cleaned-up board and chips simulate quite great. We are reusing the original thermal pad for the controller chip as we do not think it is required to replace that one with a more efficient one anyhow.

Here is a single of the 8 Jasminer X4 ASIC chips in a 45 × 45 mm package (678 square millimetres die size) with 1TB memory bandwidth, 5GB of memory and a hashrate per chip of 65 MH/s with each of the chips having 384 computing cores and 384 on-chip passes away according to the producer with a 512-bit bus width, an operating frequency of 800 to 1 GHz and a power consumption of 23 Watts.
The main controller chip on the hashing board is a Trion T120 FPGA together with 2 DDR3 memory modules best beside it (no, that is not how 5GB of memory looks like!). This is the controller chip for the Jasminer X4 ASIC chips that is being utilized on the hashing boards, the miner does have a 2nd FPGA controller chip with separate RAM chips on the primary control panel that hosts the software and web user interface of the miner, there nevertheless we find a Xilinx Zynq chip.
The next thing we wanted to attempt out here was to use a different power supply than the one the Jasminer X4 1U comes equipped with. Weve linked a 1000W Corsair HX1000i power supply (Platinum effectiveness score) to the ASIC miner in place of the stock PSU and regrettably the results were not truly that encouraging.
The other thing we desired to check with the more powerful power supply was if the Jasminer X4 1U would be able to run at 250 MHz operating frequency with the brand-new thermal user interface product in location and more than adequate power. And we do not think that the cooling of the ASIC chips is also a concern here for them not be able to run properly at 250 MHz.
Jasminer X4 does come with an extremely great thermal grease already applied, so no need to change it. The stock 300W PSU is also actually great in regards to effectiveness and is not limiting you running the miner at greater clocks. The only thing is that the stock power supply is quite loud and you may desire to modify or replace it if you are making your miner into a quiet one like we made with ours. It appears that Sunlune currently did really well with the hardware side of their Jasminer X4 ASIC miners, both in regards to performance and performance. What they could work a bit more on nevertheless is the software application side as their gadgets do not currently support dual-mining ETH/ETC-based coins in addition to ZIL, something that might quickly bring the miners an additional 30-40% profit. The absence of this function implies that a rival with dual-mining assistance already available can quickly supply the very same profitability with a less expensive gadget that has lower hashrate and/or is not as power effective as the Jasminer X4.
Weve been playing around with a Jasminer X4 1U Ethash and ETChash ASIC miner for a couple of days now and we have some more things to share with you if you are interested in the gadget. Weve currently covered some intriguing findings and possible tweaks for the Jasminer X4 1U ASIC miner here, but we continued even more trying to see and optimize the miner if we can squeeze a bit of additional performance from it. Our next apparent action was to take apart the hashing board with the ASIC chips …
Removing the eliminating cooling heatsink, a single piece for the whole boardEntire revealed the exposed Jasminer 8 ASIC chips on the hashing board along with a controller chip and two memory 2.
Weve utilized the Arctic Cooling MX4 thermal compound to cover the chips prior to reassembling the hashing board with the aluminium heatsink. It is a decently priced high-performance item that we like to utilize along with Noctuas NT-H1 due to their fantastic price/performance ratio, and there does not seem to be much point to attempt and use more pricey service anyway. When using other thermal substance ensure to put a bit more on the memory chips as there the gap with the heatsink is a bit more compared to the one of the ASIC chips.
Weve compared the hashrate and running temperature level of the Jasminer X4 1U ASIC miner before altering the thermal substance and after doing so, leaving the gadget to hash for more than 10 hours in order to get a good average of the operating temperature and hashrate. Do note that this is our currently quiet modified unit with changed fans and firmware, so your gadget might report a temperature level range and not a single number. The prior to and after outcomes are really similar, practically the exact same average hashrate and simply 1 degree Celsius difference, so there is really no requirement to play around with the thermal grease as it will not offer you much of an improvement. We likewise did a power use measurement prior to and after at the wall, the outcomes there were not much various also– 266.1 W prior to and 265.7 W after the thermal grease replacement.
