The Origins of LHR Graphics Cards. Nvidia RTX 3060

At CES in January 2021, NVIDIA appear the GeForce RTX 3060. This newest GeForce RTX graphics card was supposed to be released at the end of February 2021.

NVIDIA published the takeaways of the presentation on the official website on Jan 12, 2021, in the article titled "NVIDIA Ampere Architecture for Every Gamer: GeForce RTX 3060 Available Late February, At $329."

You tin can read the full article by following the link.

Since the annunciation of the GeForce RTX 3060, some media outlets published rumors well-nigh these GPUs being potentially limited in hash rate. In mid-February 2021, this information even so hadn't been confirmed.

On February 18, 2021, NVIDIA officially announced that they would halve the hash charge per unit for the GeForce RTX 3060 in the article titled "GeForce Is Made for Gaming, CMP Is Made to Mine".

Exactly three months after, on May eighteen, 2021, NVIDIA published another article in their web log titled "A Farther Step to Getting GeForce Cards into the Hands of Gamers." The article talks about decreasing the hash charge per unit on Ethash for the newly built GPUs: GeForce RTX 3080, 3070, and 3060 Ti, to make them less appealing for miners. These models became available at the terminate of May 2022 and were marked with a "Low-cal Hash Rate" or "LHR" identifier.

Right after this post, experts started actively discussing the term "LHR". You can read the full article hither.

On May 31, 2021, NVIDIA appear the GeForce RTX 3080 Ti and GeForce RTX 3070 Ti. You can read the full announcement here.

NVIDIA didn't brand any official statement regarding LHR in these GPUs. However, rumors near their limited hash rate on Ethash started circulating even before the announcement. After the official release and testing, it was confirmed that the GeForce RTX 3080 Ti and GeForce RTX 3070 Ti had express hash rate.

Exam Rig Specs

The test rig consisted of the following parts:

• Motherboard: BIOSTAR Hi-Fi B85S2
• CPU: Intel Pentium G3220
• Display: Intel HD Graphics
• Retentivity: DDR3 SDRAM Kingston 4GB
• HDD: Seagate Barracuda 7200.12 160Gb
• PSU: EVGA 1000 GQ lxxx+ Golden 1000W
• GPU: EVGA GeForce RTX 3080 Ti FTW3 ULTRA GAMING (1800 MHz Boost Clock, Retention Clock 19000 MHz (effective), TPD: 350 Watts)
• Two GPUs were connected to the motherboard, each through the riser PCI-E X16-X1.
• Bone: Windows ten
• Nvidia's driver: 471.68, 472.12
• Overclocking: MSI Afterburner 4.6.4 Beta 3
• Monitoring: GPU-Z

Testing was held indoors with the room temperature at +fifteen °C (59 °F).

Nosotros used PhoenixMiner to approximate the max hash rate for the RTX 3080 Ti on Ethash and Etchash algorithms. We launched the mining program on our rig with the following GPU settings: PL(%): 70, CC(MHz): +0, MC(MHz): +1000.

Correct after the launch, the program estimated a hash rate on Ethash at ~116 Mh/s, but after ii minutes it settled at ~64 Mh/s.

Thanks to pretesting, we estimated a potential hash charge per unit, without LHR lock, on Ethash and Etchash and confirmed that LHR lock leads to a ~45% hash rate subtract.

Testing lolMiner on Nvidia LHR

lolMiner is a pop mining program created past the programmer known as Lolliedieb. lolMiner's first version was released on October 28, 2018, and it supported but AMD graphics cards and a limited number of mining algorithms. Today the miner is being actively developed, and information technology supports a lot of algorithms: Ethash, Etchash, ZelHash, Equihash, Cuckoo, Cuckaroo, Cuckatoo, Autolykos, and BeamHash.

The miner supports NVIDIA and AMD and works on Windows and Linux.

lolMiner's developers constantly proceed in touch with their users on pop platforms and through social media channels.

We used lolMiner one.32a to estimate the max hash charge per unit for the RTX 3080 Ti with LHR lock on Ethash. Then we launched the mining program on our rig with the post-obit GPU settings: PL(%): 55, CC (MHz): +0, MC (MHz): +1000.

The miner estimated a hash rate on Ethash at ~63 Mh/s. Memory Controller Load, GPU Load, and Lath Ability Describe charts were stable, without significant leaps. Memory Controller Load was 66%.

And so nosotros launched the mining program on our rig with the post-obit GPU settings: PL(%): 55, CC (MHz): +0, MC (MHz): +1300.

The miner estimated a hash charge per unit on Ethash at ~65 Mh/s. Memory Controller Load, GPU Load, and Board Power Draw charts were stable, without significant leaps. Memory Controller Load was 66%.

Every bit a upshot, we estimated the hash charge per unit and confirmed that the GPU hash rate with LHR lock is ~64–66 Mh/s.

It'south of import to annotation that MSI Afterburner indexes GPUs starting from GPU 1, whereas in the log file and mining program GPUs are indexed starting from GPU 0. In this article we indicate graphics cards equally GPU one and GPU 2 most of the time, autonomously from a few occasions when we mention the data from the log file or the mining program.

LHR Unlock with lolMiner 1.32a

On September 12, 2021, the developers announced lolMiner one.32a. This was the first version with the partial LHR unlock. It featured new miner parameters and operating modes.

You lot can download the miner and learn more about it hither.

Click here to open the setup guide for different operating modes: "Nvidia Mode Switch & LHR Semi Unlock".

The description of this miner version says that the developers ran most pre-release tests on Linux systems with specific video drivers. However, nosotros decided to test the miner on Windows.

Later reading the Nvidia Mode Switch & LHR Semi Unlock guide, nosotros chose the best modes for our examination rig: LHR2 and LHRLP.

mode LHR2

We launched the mining program on our rig with the post-obit GPU settings: PL(%): lxx, CC(MHz): +0, MC(MHz): +1200.

Bat file:

lolMiner.exe --algo ETHASH --pool eth.2miners.com:2020 --user WALLET_ADDRESS.RIG_3080Ti --fashion LHR2 --tstop 70 --tstart l --log on --logfile log_lolMiner_RIG_3080Ti_mode_LHR2.txt --timeprint on --longstats 30 --statsformat gpuName,speed,poolHr,shares,sharesPerMin,bestShares,power,hrPerWatt,coreT,juncT,memT,coreClk,memClk,fanPct

The miner estimated a hash rate on Ethash at ~50 Mh/due south. The hash rate didn't abound. Retentivity Controller Load, GPU Load, and Board Ability Depict charts, besides as other Power charts, showed slight parameter instability. Retention Controller Load was 66%.

After reviewing the log file, we established that LHR lock got activated at the DAG generation stage:

GPU 0: detected mining lock - attempting to improve performance...
GPU 1: DAG build complete 100%
GPU 1: DAG generation completed (3446 ms)
GPU 1: DAG verification passed
GPU one: detected mining lock - attempting to improve performance...

The text of the log file didn't contain 'Unlock'.

And so we ran a few more tests in LHR2 mode fixing the frequency and voltage. We used the Voltage/Frequency Curve Editor in MSI Afterburning. We failed to unlock LHR with Nvidia'due south drivers 471.68, so we decided to install Nvidia's drivers 472.12 to the rig.

During nearly tests the miner remained unstable, but we managed to get decent results past trial and fault. Here is how we did information technology.

Nosotros launched the mining program on the rig with the following GPU settings: PL(%): lxxx, CC (MHz): -502 fix Voltage(mV) 825, MC (MHz): +chiliad.

GPU1: CC value settled at 1050 MHz. Two minutes after the miner launch the hash rate was ~82 Mh/south.

GPU2: CC value settled at 1095 MHz. Two minutes later the miner launch the hash rate was ~82 Mh/s.

After ane 60 minutes of functioning the miner showed a hash rate of ~76–78 Mh/s.

mode LHRLP

Afterwards reviewing the log file, we established that LHR lock got activated 7 times for each GPU in the outset 25 minutes of functioning. So the hash rate settled.

Memory Controller Load, GPU Load, and Board Power Draw charts, as well equally other Power charts, showed slight parameter instability. Retentiveness Controller load was 88–100%.

And then we ran a few tests in LHRLP mode both fixing and not fixing the frequency and voltage. We used the Voltage/Frequency Curve Editor in MSI Afterburner. During most tests the miner remained unstable, but we managed to become decent results.

We launched the mining programme on the rig with the post-obit GPU settings: PL(%): 80, CC (MHz): -502 fix Voltage(mV) 825, MC (MHz): +k.

Bat file:

lolMiner.exe --algo ETHASH --puddle eth.2miners.com:2020 --user WALLET_ADDRESS.RIG_3080Ti --style LHRLP --tstop seventy --tstart 50 --log on --logfile log_lolMiner_RIG_3080Ti_mode_LHRLP.txt --timeprint on --longstats thirty --statsformat gpuName,speed,poolHr,shares,sharesPerMin,bestShares,power,hrPerWatt,coreT,juncT,memT,coreClk,memClk,fanPct

GPU1: CC value settled at 1050 MHz. Two minutes afterwards the miner launch the hash charge per unit was ~82 Mh/s.

GPU2: CC value settled at 1095 MHz. Two minutes afterwards the miner launch the hash charge per unit was ~82 Mh/s.

After one hour of operation the miner showed a hash rate of ~78–fourscore Mh/s.

Afterward reviewing the log file, nosotros established that LHR lock got activated four times for each GPU in the first 19 minutes of operation. And then the hash rate settled.

Memory Controller Load, GPU Load, and Lath Ability Draw charts, likewise as other Ability charts, showed slight parameter instability. Memory Controller load was 88–100%.

With the release of the new miner version, we stopped further testing.

Conclusion: lolMiner 1.32a can partially unlock LHR. The miner shows a hash rate of ~78–80 Mh/s which is ~67–69% of the potential max hash rate.

The clarification of the release says the following: "Recommended drivers for LHR2 and LHRLP: 470.63.01 or 465.31 — others could exist more unstable. Most tests were done in Linux."

2Miners recommends Linux-based mining systems like RaveOS for this miner version to ensure stable performance.

LHR Unlock with lolMiner 1.33

On October 1, 2021, lolMiner 1.33 was announced. In this version the developers worked on LHR unlock. They improved LHR unlock performance and recommended specific drivers.

In the offset 4 minutes of operation, the miner was "calibrating to your exact core and memory clocks". Hither is what these notifications look like in the log file:

GPU 1: please wait LHR semi-unlock calibration is ongoing...
GPU 0: delight wait LHR semi-unlock scale is ongoing...

If LHR lock is activated during mining, the miner lowers the lhrtune parameter when unlocking LHR:

GPU 1: detected mining lock. Unlocking & reducing --lhrtune parameter...
GPU 1: GPU volition be paused to brand sure it is unlocked...
GPU 0: detected mining lock. Unlocking & reducing --lhrtune parameter...
GPU 0: GPU will be paused to brand sure it is unlocked...

The duration of the examination was xxx hours and 33 minutes.

After reviewing the log file, nosotros established that LHR lock got activated four times for each GPU in 26 hours of operation.

GPU Load and Board Power Draw charts, every bit well as other Power charts, showed slight parameter instability. GPU1's Memory Controller Load chart was stable, while GPU2's Memory Controller Load chart was significantly unstable.

Below is the Stats page of the pool with the results of the miner operation.

Based on the number of shares sent to the pool, we estimated the hash rate later on 30.55 hours of the miner operation. Initial data for two GPUs: 2051 shares in 30.55 hours, share difficulty is 8726 M. We multiplied the number of shares per second by share difficulty and got 162.vii Mh/s. This is a hash rate of ii GPUs, so a hash rate of one GPU is ~81.36 Mh/due south. Nosotros tin also estimate the hash rate per GPU taking into business relationship the number of shares solved by each GPU (GPU1: 1034, GPU2: 1017): GPU1 – ~82.04 Mh/s, GPU2 – ~fourscore.69 Mh/s.

We recommend extending the testing period to become statistically correct results: each bill of fare should send over 5000 shares to the pool.

Decision: lolMiner one.33 can partially unlock LHR. The miner shows a hash rate of ~81 Mh/due south which is ~lxx% of the potential max hash rate. In the description of the release you can observe specific video drivers recommended for each GPU for the optimal stability.

LHR Unlock with lolMiner ane.34

On October 18, 2021, lolMiner one.34 was announced. In this version the developers improved the LHR unlock feature, recommended specific drivers, and fixed previously discovered errors. You tin notice the –lhrtune value and the number of LHR locks in the summary stats chart in the mining program or in the log file.

The duration of the test was 2 hours and 33 minutes. In the kickoff 4 minutes of performance, the miner was calibrating "LHR semi-unlock". LHR lock got activated once. Board Ability Describe charts, as well as other Power charts, were slightly unstable. GPU Load and Memory Controller Load charts were stable. The miner showed a hash rate of ~82 Mh/s.

We tried increasing the memory clock.

We launched the mining program on our rig with the following GPU settings: PL(%): 70, CC (MHz): +0, MC (MHz): +1200.

The bat file is the same.

Information technology resulted in the abiding activation of LHR lock for GPU2. GPU1's GPU Load and Lath Power Describe charts, as well equally other Power charts, showed slight parameter instability. GPU1's Memory Controller Load nautical chart was stable. GPU2's charts were significantly unstable.

Nosotros lowered GPU2's memory clock. We launched the miner with the following GPU settings:

GPU1: PL(%): 70, CC (MHz): +0, MC (MHz): +1200.
GPU2: PL(%): 70, CC (MHz): +0, MC (MHz): +1000.

The elapsing of the test was 61 hours and 30 minutes.

After reviewing the log file, we established that LHR lock got activated 3 times. Board Power Draw charts, as well every bit other Power charts, were slightly unstable. GPU Load and Memory Controller Load charts were stable.

Below is the Stats page of the puddle with the results of the miner operation.

Based on the number of shares sent to the pool, we estimated the hash rate after 61.5 hours of the miner operation. Initial data for 2 GPUs: 4089 shares in 61.5 hours, share difficulty is 8726 M. We multiplied the number of shares per second past share difficulty and got 161.2 Mh/due south. This is a hash rate of 2 GPUs, so a hash rate of i GPU is ~80.58 Mh/s. Nosotros tin also approximate the hash rate per GPU taking into account the number of shares solved by each GPU (GPU1: 2090, GPU2: 1999): GPU1 – ~82.37 Mh/s, GPU2 – ~78.79 Mh/southward.

We recommend extending the testing catamenia to get statistically correct results: each carte du jour should send over 5000 shares to the pool.

Determination: lolMiner 1.34 can partially unlock LHR. The miner shows a hash charge per unit of ~80 Mh/s which is ~69% of the potential max hash charge per unit.

In the description of the release you can detect specific video drivers recommended for each GPU for the best stability.
