NOTE: This miner does NOT monitor GPU temperatures.
It is up to the user to ensure that GPU(s) are functioning within safe power and temperature limits.

API: The miner includes a read-only api based on the sgminer-5.5 API.
Both the json and text formats are supported. For more details, we refer to the sgminer api documentation.

Software Requirements:

• Supported GPU driver (see GPUs Supported above)
• For cryptonight v8 on linux, only amdgpu-pro drivers are supported. Version 18.30 or newer is needed for Vegas. ROCm is not supported.

This miner includes the following dev fees:

• Cryptonight v8: 2.5%
• Lyra2z: 3%
• Phi2: 3%

This is the tuning guide included in the release, posting it here as well for people to read before they download.

A noteworthy fact not mentioned below is that we also asked two forum members not affiliated with us in any way, dragonmike and N2DCRYPT, to verify the miner hashrates for us on their rigs in an early test release. If someone asks, I'm sure they will present their own benchmarks. Imho, their results were in line with our own testing presented below.


Team Red Miner CNv8 Tuning

Background

This miner is more lean than other CN miners. This can translate into either increased hashrate, lower power draw, or both, or none of the above. Your mileage may vary and is highly dependent on mem straps and clocks. If running at the same hashrate as other CN miners, you can expect your power draw to decrease between -5-20W per gpu depending on gpu model and clocks.

To enable a higher hashrate, this miner generally requires a higher _core clk_ than normally used in CN mining. Unless you go nuts, your power draw will most probably be lower than that of other miners at lower clocks in the end anyway. This is the only way to achieve a > 2200 h/s read on a Vega 64.

There are fewer controls in this miner than the standard CN miner. It always runs with two threads, and you control the intensity per thread in the range 1-16. Moreover, you can choose between two modes, + and -. The mode will most often not have any effect on the end result, but it never hurts to try it.

Tuning guide

[Windows drivers]
For some Polaris cards, the good ol' blockchain driver works fine. However, the one driver that seems to be a good fit across the board is 18.6.1, and that's the driver we have used in all our Windows tests.

[Linux drivers]
You need the amdgpu-pro 18.30 drivers for your Vegas under linux to reach the max possible hashrate. Also, please note that this release does not include ROCm support for CNv8, it will be included in an upcoming release instead.

[Polaris cards (470-580)]
The standard configuration is 8+8 for all of these cards. 7+7 might give the same optimal hashrate, and 9+9 can, especially under linux, give a better result for 480/580. For some cards, 16+14 is the best choice but also increases the probability of stale shares. You must have good mem straps to reach a good hashrate. Normally e.g. the Pimp My Straps function in SRB Polaris Bios Editor is sufficient. For mem clk, boosting it as much as possible while avoiding mem errors is a good thing. The core clk should generally end up between 1230-1270. For 580s, a boosted core clk to 1300 can push the hashrate to 1100 h/s while still staying at a reasonable power draw. We have seen few Polaris cards not being able to reach 1020-1030 h/s with this miner when the proper mem straps are in place.

[Baffin cards (550-560)]
We have not optimized this miner for Baffin yet. We have run some small tests, and we think the miner will be competitive on these cards as well. For a 560, 4+4 should be a good configuration. Let us know your results!

[Vega cards]
The Vegas can end up anywhere from 1900-2270 depending on if it's a 56 or 64, a reference card or not and your choice of clocks. The interesting configurations to try for your Vega are 14+14, 14-14, 15+15, 16+14. You can also try 16+15, 15+14, etc. The mem clk is very important, and you should aim for as high as possible while keeping your rig stable. If you have a Vega 64, please don't be shy to try a higher core clk. The 16+14 configuration will often not show its true capability before hitting 1500 core clk. Your power draw should still stay reasonable (as in lower than other miners at more standard clocks). For a lower core clk around 1408, some cards do best with 16+14, others with 15+15, some with 14+14, YMMV.

[Older cards]
We're sorry, we only support 470-580, 550/560 and Vega cards.
