I have successfully upgaded my HP ThinClient T620’s memory and hard drive, also installed Windows 7 64 Bit and Windows 10 64 Bit to it.
Here are some screenshots from Windows 10 installation. Memory upgrade to 8G, and hard drive changed to 120G. Default Spec:
- 1.5 GHz AMD GX-415A Quad-Core APU
- 4GB of 1600 MHz DDR3L SDRAM
- 8GB Flash Storage
- AMD Radeon HD 8330E Graphics (512MB min)
T620 system features 2 x USB 3.0 ports, 6 x USB 2.0 ports (2 ports are in the chassis), and 2 x PS/2 ports. The integrated AMD Radeon HD 8330E graphics card is designed to deliver a sharp, clear picture and you may connect up to two simultaneous displays using the two DisplayPort 1.2 video outputs. For connecting to the Internet, this Thin Client includes an integrated Gigabit Ethernet controller. While the system does have 4GB RAM, a minimum of 512MB is reserved for the integrated graphics controller. The HP t620 Flexible Thin Client uses a 65W power supply that runs on 100-240VAC at 50-60 Hz and is ENERGY STAR qualified and EPEAT Gold registered.
I added one Wireless adapter and it was not identified at the beginning. I manually installed this adapter’s driver later. Other drivers will still need to be updated, such as sound card, video card, and network card.
The installation process is recorded in this video for Windows 10 and Windows 7.
For windows 7 32bit, the driver link is :

For Windows 7 64bit and 10 64bit, the driver link is :

Windows 10 video card drive was not identified properly. I have found the right video drive r. For others, such as sound card and network card, once I got all right drivers updated, I will upload it to my Google Drive and share it out. Keep posted.

Performance
I used Google Chrome to play 1080p and 720p YouTube video. CPU is a bottleneck here. CPU when playing 1080p is consistently staying 100% usage. It causes intermittently pause while watching video. 720P is much better.
Power consumption is about 14 Watts. I am thinking about to install a CentOS on it and running some services for my home lab.

Hi,
May I know what is the version of your updated AMD Radeon HD 8330E Graphics driver ?
On the HP site only it was 15.201.1501.0000 released jan 2016.

This is your updated driver which you uploaded AMD_Radeon_R9_25_20_15003_5010_Win10_X64 and you are using this one.
I just tried installing windows 10 pro x64 on 2 different t620s and had issues on both. When it rebooted from the initial install it got stuck at the ‘please wait’ screen, froze, and then rebooted. Could you describe how you setup the BIOS, which windows image you used, and take it step by step that way? Your install looks much simpler than mine.
Hi Bob,
I did not meet any issue when install win10 on my T620. Not sure why you had it. must be some hardware related issue. Can you check the hardware to see if there is any difference? I used some old images, 2018 Aug one. Maybe that is a reason. You might try to get 2018 or early 2019 images to give it a try.
