oh...

There's a strange thing about this dual micro SD card adapter.

When I transfer files to the micro SD cards, it blocks wifi internet!

Do you guys know why this happens?

Is it because the adapter is placed at WAN card slot? but I'm using a USB wifi dongle.
I'm unsure how that can affect USB wifi dongle

EDIT: this doesn't happen all the time...

 

I mentioned before that these mini PCIe slots can support both PCIe traffic and USB traffic. (A Wi-Fi card uses both, PCIe for Wi-Fi and USB for Bluetooth.)
Pretty sure that these SD card adapters just use the USB mode. It's basically a USB card reader in PCIe form factor. So, it's probably gobbling up all of the bandwidth on the USB bus when a file transfer is going on.

You could possibly get around this by using a USB 3.0 Wi-Fi dongle, if you're not already. (mPCIe only supports USB 2.0.)

 

I kinda noticed my i7 4810MQ has been spiking to high 80s time to time.. Maybe I should consider a 4930MX or 4940MX sometime soon. It should be better at thermals than the 4810MQ right? I can install the 4810MQ into my Zbook 15, and keep the 4710MQ around as another spare.

 

Thanks for your response.
Yes, I'll try a USB 3.0 wifi dongle.

I found that this only happens when I try to transfer files from USB 2.0 drive to the micro SD cards!
You're right about that. When I transfer files from USB 2.0 drive to the PCIe adapter micro SD cards, they take up the USB 2.0 bandwidth ... so USB 2.0 wifi dongle won't work.

I learned that SATA to micro SD file transfer won't interfere the wifi dongle...

 

My 4940mx runs at 96-98c during full load with delta fans on max, and 48-53c in idle using thermal grizzly kryonaut.
I don't think you will get better temps putting a more power hungry cpu in it.

Some stresstest Heavyload for 15 minutes

 

4810MQ = 47W TDP
4930MX & 4940MX = 57W TDP
Higher power = more heat (that's just physics). I would not expect these to run cooler...

You can cool the CPU off by disabling turbo boost when you don't need it. (You can set CPU utilization to 99% max in Windows power settings, and then use the system tray power slider to enable/disable turbo boost easily. With this setting, it will only be enabled when the power slider is all the way to the right.) Also make sure to blow out your fans & heatsink fins if it's been several months since they were last cleaned.

 

Would it run any cooler if I have them clocked at 4710MQ/4810MQ speeds? On balanced profile in Windows?

 

Then it would be basically the same. There's nothing fundamentally different about these CPUs. They have the same CPU architecture and the same number of cores.
...You could also look into undervolting to reduce the temperature a bit? I think 4th gen was the first generation where it was viable.

 

Locked multiplier at 29 to replicate 4810MQ base frequency at ~2.8ghz.
I don't know what stock voltage the 4810MQ run at?
Heavyload running with fans on full speed.
Big difference in temp. Barely any heat being made.

 

either joining the cpu+gpu heatsinks or creating a custom singular heatsink would be neat for this laptop, maybe simply joining it with a pipe + heatsink plaster (star922) would be sufficient
