WTF?! Laptop computer mining farms and varied workarounds for Nvidia’s hash fee limiters helped miners navigate the GPU scarcity with ease final 12 months on the expense of many offended players. This 12 months, a Chinese language firm has began transplanting cellular Ampere GPUs onto desktop graphics playing cards, which is each bit as worrying because it sounds.
Nvidia might have a brand new downside on its arms that comes simply as the corporate is coping with a large ransomware assault. In response to a put up on Weibo noticed by cnBeta, a Chinese language firm is at present promoting modified GeForce RTX 3060 graphics playing cards on one of many nation’s hottest on-line second-hand marketplaces.
The modded graphics playing cards reportedly use recycled RTX 3060 laptop computer GPU dies as a approach to circumvent Nvidia’s Ethereum hash fee limiter, often called Lite Hash Charge, or LHR for brief. Nvidia utilized this resolution with the RTX 3000 collection GPUs in an try and make them much less interesting to cryptocurrency miners. Nonetheless, the corporate didn’t do that with all Ampere GPUs, and one such exception is the RTX 3060 laptop computer GPU.
Most miners consider Nvidia’s effort was pointless, and for some time they’ve continued to purchase LHR RTX 3000 graphics playing cards with out worrying an excessive amount of in regards to the hash fee limitations. Again in August 2021, mining software program NBMiner was up to date to enhance the hash fee to round 70 % of what it could be with out the limiter in place. A number of months later, one other resolution popped up on-line that went even additional than that. The pattern even impressed a malware marketing campaign designed for individuals who have been desperately on the lookout for the perfect resolution.
What’s attention-grabbing in regards to the modified RTX 3060 graphics playing cards is that an organization was someway capable of safe GA106 dies destined for laptops and switch them into desktop graphics playing cards. Whereas corporations like Nvidia and AMD additionally do that to carry entry-level desktop graphics playing cards to market with minimal R&D and manufacturing prices (the notorious RX 6500 XT involves thoughts), this can be a quite sudden improvement.
It’s price noting the GA106 die used within the Chinese language RTX 3060 contraption has 3,840 CUDA cores, barely greater than the three,584 CUDA cores present in a daily desktop RTX 3060 GPU. Nonetheless, the corporate that makes it solely paired the cellular GPU with six gigabytes of GDDR6 reminiscence, which is sufficient for mining functions.
Miners can apparently seize these playing cards for as little as $540, and one vendor demonstrated 9 of them in a single rig mining at nearly 250 MH per second utilizing 910 watts from a wall socket. It’s not fairly as loopy because the mining farms based mostly on Ampere laptops we noticed final 12 months, nevertheless it does beg the query if an analogous remedy can be utilized to different RTX 3000 laptop computer GPUs sooner or later.
