Small issue with laptop gpu when EGPU is connected

[Farside35]

Hey everyone,

I've been mining with a laptop for a little while (Acer triton 300 se with RTX 3060) and got a hashrate of about 38/39 mh/s.
Recently i've purchased an EGPU with a RTX 3080. This has been working pretty well and got a hashrate of 99 mh/s on the 3080.
The issue though is that whenever I connect the EGPU, the laptop GPU hashrate drops down to about 26 mh/s and only uses about 60W power (instead of 80W it normally does). Removing or changing the OC settings doesn't do or fix anything.
The EGPU doesn't give any problems.
Tried different miners (t-rex, gminer, excavator with NH quickminer), so I assume it's a hardware issue.

Does anyone have an idea what could cause this? Installed the latest nvidia drivers for both cards. Updated the BIOS. Been searching the internet for a solution, but can't find anything. So i'm trying my luck here.

Thanks!

Damn that 3080 eGPU costs how much? I like your idea I might try this one day myself, I think the laptop needs more power, try changing the power setting from optimal performance to highest performance and see what happens.

It seems that when you connect your eGPU, your OS is changing the main video to eGPU and leave your 3060 in idle mode
In the past we used adaptors to have a card mining at 100% speed, like a HDMI-VGA

To see if this is the real problem, connect your 3060 to a monitor instead of the laptop screen, this can force your 3060 to work
Another thing, you can follo suggestion above and change settings on windows to never turn of screen and never goes to sleep: https://www.howtogeek.com/714618/how-to-stop-windows-10-from-turning-off-your-screen/

I've never seen where you can run two gpus on a laptop at the same time, its never going to work, some laptops comes with two gpu, one on the CPU integrated and other standalone and even if you install a driver for both one will have to bow for the other when you want to play games.

Running two or more graphics cards at the same time like we used to do on a PC or through SLI is only possible on a desktop computer not a laptop computer, there are some drawbacks to catch here, you power a laptop with an adapter right? What about a desktop? You see the difference?.

I don't know if laptops have up to two thunderbolt connections for more than one eGPU, I think 🤔 it's possible to run two GPU on a laptop this way because eGPU has their power separately.

He is using eGPU guys

eGPU uses external power source, not the power from laptop, this is the special thing about eGPU

He is using the 3060 from laptop, not eGPU, and the 3080 is from eGPU


This is an eGPU: https://www.amazon.com/Razer-Core-Thunderbolt-External-Enclosure/dp/B07CQG2K5K/ref=sr_1_4?crid=3CU55VFTO0R70&keywords=egpu&qid=1649170473&sprefix=egp%2Caps%2C204&sr=8-4
You can use an external GPU on your laptop, with external power source to provide the necessary power to use  your GPU, not limited by laptop

Ah he said he is already using both, the only issue is the hashrate reduced for the 3060

Nvidia has different drivers for desktop and mobile GPUs, so I'd start there.

You can use more than one eGPU on a laptop but running a Laptop GPU at the same time with a eGPU will surely result in losing a few hashrate, this can be because of RAM limit, what's your laptop's spec?.

Hello, have you checked your virtual memory (and try ton increase it) if you are mining with Windows. I often had the issue when trying to mine with several cards

Hi there! Have any of you had problems with the touchpad on your laptop? Personally, I've had cases where the touchpad just stopped responding to touch and restarting the laptop didn't do anything.

This question does not belong on a mining forum. Better ask the manufacturer of your laptop or forum.
If the laptop still falls under warranty/guarantee do a RMA as probably your touchpad might be broken.

Do you know what you are saying? Increase Virtual memory to do what? Gain more hashrate? OP isn't trying to mine coins with several graphic cards on a laptop learn to read very carefully before typing.
