Performance is sluggish with minimal memory use.
Performance is sluggish with minimal memory use.
Hi, I have three GPUs facing the same issue. I own a single RTX 2060 Super, one RTX 2080 Ti, and one CMP NVIDIA P106-100. The cards show low memory utilization and low hashrate. The 2080 Ti uses about 17% memory with 4MHs, the 2080 Super consumes 40% memory at 20MHs, and the P106 uses only 4% memory with no hashrate. I changed the riser, power supply, and other settings, but there were no problems with NVIDIA MATS. All devices passed testing, yet mining still isn’t working—I’d really appreciate any advice or information.
Update your post to include full system hardware specs and OS information.
Include PSU(s): make, model, wattage, age, condition?
Have the PSUs been used for previous mining efforts? (Noted that you changed PSUs - need information for both.)
What mining software are you using?
Hi, thanks for your message.
I have a Core i5 9th generation system with 16GB RAM, an ASUS MB motherboard, a 240 SSD, and risers ver 009s with all 12V MOLEX connectors. The power supply is quiet and efficient, delivering around 700W in bronze and 850W in high-end models—no issues there.
My setup includes three GPUs (3070, 3080, and an 2080 Ti) using the same base configuration: MB motherboard, RAM, SSD. I’ve used QuickMiner for mining because of its OC settings, but I’ve also tried T-Rex, Phoenix, and Excavator. All of them show similar performance—low hashrate and memory usage. GPU-Z confirms low memory consumption on the GPUs.
I have a dedicated PC for testing GPUs, and there’s the same issue there too. With a 750W power supply, changing the risers didn’t help.
Temperatures are very low because the card power draw is minimal when mining. I can adjust power limits in tools like NiceHash or Afterburner, but the percentage of power used by the GPU stays consistent with memory usage.
For the 2080 Ti, my configuration on OC shows 100% memory usage, around 60 MH/s, and about 150W power consumption. On my current rig, data usage is lower (40% memory, ~20 MH/s), and power draw is roughly 50W.
Apologies, my English isn’t great—please accept my apologies.
Thanks a lot!
