LHR is made to stop Ethereum miners and get more GeForce graphics cards into the hands of gamers. What you need to know is listed below.
It’s hard to be a PC gamer right now. Because there aren’t enough GPUs, it’s almost impossible to buy the best graphics cards, and when you do find one, it’s usually at a crazy markup. Even worse, digital currencies like Bitcoin and Ethereum have been doing very well in 2021 and 2022. This has caused hordes of GPU miners to buy up all the graphics cards they can find so they can mine crypto coins and make a nice profit, sometimes in “farms” made up of rows of working GPUs.

Nvidia’s Lite Hash Rate (LHR) technology put strict limits on the mining performance of some GPUs, ostensibly so that gamers could get their hands on more graphics cards. This was done to help gamers deal with the lack of GPUs. Here’s a rundown of what LHR does, which graphics cards have the technology if gaming performance is affected (spoiler: nope), and everything else you need to know.
What Is Lite Hash Rate Technology From Nvidia?
First of all, what exactly is LHR? When Nvidia LHR graphics cards are being used to mine the Ethereum (ETH) cryptocurrency, the “hash rate” is automatically cut in half. Without getting too deep into the details, this makes it less profitable to buy LHR GPUs for mining because they use more power for a lower hash rate. The idea is that gamers will buy LHR GPUs instead of miners if miners can’t make money with them.
LHR tech was first used in the GeForce RTX 3060, but it broke quickly and had to be fixed. It was then put back into use.
The first time the GeForce RTX 3060 tried to add the Lite Hash Rate limiter, it didn’t work out as planned. The GPU’s full mining power was unlocked the same week it came out when a beta driver was released by mistake. Still not giving up, Nvidia tried LHR technology again in most of its products two months later. The firmware and software on the newer LHR GPUs, like the RTX 3080 Ti, are said to work together much better. Will the limiter still work in the long run? No one is sure. Recent news says that NBMiner can now unlock up to 70% of an LHR GPU’s mining performance.
This is up from 50%, which is all that LHR lets them do out of the box. Cryptocurrency is a big business right now, and miners who want to make more money will try to break Nvidia’s security. Be careful about what you download, though. One well-known “LHR unlock tool” actually installed a Trojan on people’s computers instead.
What GeForce GPUs have LHR?
Here are the GeForce graphics cards that include LHR technology.
- Nvidia RTX 3050
- Nvidia RTX 3060
- Nvidia RTX 3060 Ti (Founders Edition unaffected)
- Nvidia RTX 3070 (Founders Edition unaffected)
- Nvidia RTX 3070 Ti
- Nvidia RTX 3080 (Founders Edition unaffected)
- Nvidia RTX 3080 Ti
In the middle of May 2021, Nvidia put LHR on most of its RTX 30-series cards. If you already have an RTX 3060 Ti, RTX 3070, or RTX 3080 made before the change, their mining performance will not be affected in any way. (That’s why Nvidia’s own limited-run Founders Edition models don’t support LHR—they were all made before Nvidia made its limiter.)
After the switch, LHR technology is built into every GeForce GPU made. Well, almost all of them. The work-hard-play-hard GeForce RTX 3090 never got LHR, and all models offer full hash rate performance.
The huge RTX 3090 is the only GeForce RTX 30-series GPU that doesn’t have LHR. It can be used for both work and play.
How Do I know If My Video Card Is An LHR GeForce?
No matter which model of RTX 30-series card you buy, the box will say “LHR” or “Lite Hash Rate” in some way, so you’ll know you’re getting an LHR GPU. Radeon graphics cards, which compete with AMD, do not have any restrictions on hash rate at the moment.

Does LHR Affect How Well You Play Games?
Don’t worry about Nvidia’s Lite Hash Rate tech if you’re a gamer. So far as we know, it does not affect how well games run. This is just a limiter for the hash rate.
What Does LHR Mean In Terms Of Resale Value?
The value of used LHR graphics cards could go up or down. Some people might value these models more because LHR means that a graphics card probably wasn’t used for mining. On the other hand, miners will value them less because they will work less well for the price.
If you’re a miner, you should probably stay away from LHR GPUs until more restrictions are lifted on them. Still, if the profit from crypto mining goes up, miners may be able to use these even though they don’t work as well.
