LHR Cards: How to unlock the Lite Mining Hashrate

To understand what LHR Mining Hashrate means you need first to understand who created this and why they create it.

Starting February 18, 2021, Nvidia announced that it will lock mining cryptocurrencies capability in its graphics cards using LHR block to give the chance to gamers to get their hands on graphic cards, which became time unavailable in the markets due to the constant demand from miners to buy all the cards available in stocks.

We are gamers, and designed GeForce GPUs for gamers; With the launch of GeForce RTX 3060, we’re taking an important step to ensure GeForce GPUs end up in the hands of gamers.

MATT WUEBBLING, the vice president of Global GeForce Marketing.

NVIDIA decided to split miners away from gamers by manufacturing specific cards for each group, gamers’ cards can not mine crypto efficiently, in addition, miners cards ( Nvidia CMP cards ) can not do graphics and lack display outputs; which ensures solving the GPU shortage problem and help gamers and miners always find their needs available in the stock markets’ shelves in suitable prices.

How did NVIDIA Lite Hashrate block 100% mining hashpower and decreased the mining hash rates in its new cards?

Any NVIDIA LHR-labelled graphic card is programmed to detect any repetitive computing task such as mining Ethereum ( ETHhash Algorhitm ) and automatically limit it; This ends up decreasing these cards’ Ethereum mining hashrate to only 50%, which makes these cards useless and non-profitable consuming power and have only 50% mining performance.

Which algorithms are affected by Lite Mining Hash rate?

• DaggerHashimoto [ EtHash – (ETH) & (ETC) ] Ethereum Mining Hashrate: 50% Out of the box
• KAWPOW ( Ravencoin – RVN ) Mining Hashrate: initially was not affected.
• Autolykos2 ( Ergo ) Mining Hashrate: initially was not affected.

Which graphic cards are affected and how to know if your GPU is LHR or FHR?

Firstly, NVIDIA Geforce RTX 3090 & RTX 3090 TI: Not limited at all, all RTX 3090 cards mine normally in the full hashrate mode (FHR); therefore, If you are going to buy one of these cards, do not worry, and feel free to buy it from any brand, manufacturer, or any retail or online store without hesitation.

Secondly, RTX 3080 Ti: all editions from all brands are Lite Hashrate limited for Ethereum mining.

Thirdly, Nvidia RTX 3070 Ti: all editions from all brands are Lite Hashrate limited for Ethereum mining.

Moreover, RTX 3080 – RTX 3070 – RTX 3060 & 3060 TI ( usually called Semi-LHR cards ): some editions are Lite Miners & others are FHR, and this is the guide to distinguishing between LHR and FHR versions:

MSI Lite Hashrate Cards: “LHR” will always be written beside the “SKU number” or in the GPU description, for example:

For instance, MSI Gaming GeForce RTX 3080 (LHR)10GB GDRR6X 320-Bit – HDMI/DP Nvlink Torx Fan 4 RGB – Ampere Architecture OC Graphics Card (RTX 3080 Gaming Z Trio 10G LHR)

---

ASUS Lite Mining Hashrate Cards: always have V2 ( Version 2 label ) in the GPU description:

For example, ASUS ROG Strix NVIDIA GeForce RTX 3080 (V2) OC Edition Gaming Graphics Card – (PCIe 4.0, 10GB GDDR6X, (LHR), HDMI 2.1, DisplayPort 1.4a, Axial-tech Fan Design, 2.9-Slot, Super Alloy Power II, GPU Tweak II)

GPU Chip Number can tell if it is a Lite miner card, it is not usually shown on the card outer box; you need to unbox the graphic card and detect it on an operating system. 

Old Chip: some editions are Lite miners & others are FHR

New Chips: all editions are Lite mining limited.

RTX 3080 Chip	Old: GA102-(200)-A1	New: GA102-(202)-A1
RTX 3070 Chip	Old: GA104-(300)-A1	New: GA104-(302)-A1
RTX 3060 TI Chip	Old: GA104-(200)-A1	New: GA104-(202)-A1

RTX 3060 Cards: the original version of RTX 3060 is Driver Limited, which can be unlocked through the NVIDIA 470.05 driver, which is available on Reddit because Nvidia deleted this unlocking driver from its developer page; While the new SKU Versions of RTX 3060 are ALWAYS Lite Mining Hashrate limited.

RTX 3060

Original Chip: GA106-300-A1 Driver Limited

New GPU Chip Number: GA106-302-A1 Lite Hashrate limited

Founders Edition: some editions are LHR & others are FHR and these versions can be only differentiated by their Chip numbers also.

How to unlock the lite hashrate limit to mine cryptos using your card in the full hash rate mode (FHR)?

The vast majority of crypto miners have already applied new programs to partially unlock nearly 70% of these cards mining hash rates, and here are the most effective miners that could unlock LHR mode:

NBMiner LHR Mode: -lhr <value> Command will try to unlock the Lite Hash Rate according to this <value>

• –lhr <value> Partial unlock hashrate for Nvidia LHR GPUs.
  • [-1, 100].
  • 0: auto
  • -1: off.
  • Others: set to 74 means trying to reach 74% of max hashrate.

• –lhr-mode, –lm <modes> LHR unlock mode for Nvidia LHR GPUs. 1 or 2.
  • 1: higher max hashrate, higher power consumption
  • 2: lower max hashrate, lower average power consumption

• –lhr-reduce-value, –lrv <value> The amount of -lhr value reduced each time when GPU hits LHR lock

• –lhr-reduce-time, –lrt <time> The -lhr value will reduce by value if the time since last lock

• –lhr-reduce-limit, –lrl <limit> Limit the times of -lhr been reduced.

NiceHash Miner: achieves about 68% mining hashrate in most LHR Cards by automatically recognizing LHR GPU and enabling LHR unlocking mode via Excavator and LolMiner.

T-Rex Miner LHR Mode: has Autotune-mode which detects LHR GPUs and automatically activates the LHR unblock.
