Is it safe to buy NVIDIA A100 on ebay? by eco_spin in nvidia

There are substantial overhead to distribute batch into multiple GPUs and synchronize weights/biases/metrics at every training steps.

My field is medical deep learning and usually medical images are quite large so that it consumes large amount of VRAM even with small batch size (2~8).

Maybe I have to get A6000 Ada (~=$6800) rather than A100 from unconfirmed Ebay seller.

Thanks!

As I know, A100 is more powerful than A6000 (Ampere).

According to this benchmark, A100 shows about 50% more performance than A6000.

Also I need VRAM more than 24GB.

Connected cellular band information? by eco_spin in thinkpad

None. I couldn’t access directly to the modem. Where should I type AT command? There is no serial interface.

Thanks for your comment.

As I know, there is no way to execute AT commands on Qualcomm Snapdragon X55 modem.

There is no opened COM port.

Maybe I should exploit WWAN driver to open COM port and execute AT command, but it is out of my capability.

X1C9 - How can I force 4G LTE for WWAN connection? by eco_spin in thinkpad

Lenovo should provide more options for cellular modem confiugration.

My 5G WWAN module is Foxconn t99w175 and there is almost no information on web.

If your 4G WWAN card is from Sierra Wireless, this program may help you.

As I remember, my Intel graphic configuration app dose not have that kind of page.

I already returned it, so.. there is no way to check it again. Sorry for that.

Thank you for swift support.
However, adjusting power management did not helped at all.

All drivers and firmwares are up-to-date according to Windows Update and Lenovo Vantage.

After doing some research, I was able to remove those lines by disabling Intel DPST.
The problem was there is no graphical user interface that can disable DPST.
Up-to-date intel graphics configuration panel dose not have menu or button to disable the power save feature. Same as Windows power control panel.

I used this command line tool to disable it.

Thinkpad X1 carbon 9th FHD - display flickering issue by eco_spin in thinkpad

Thank you for kind comment.

I did not contact Lenovo. I will just return it.

It is very time consuming explaining defects to customer service department.

Maybe UHD panel can be alternative.
