ADT R43SG unstable connection on HP elitedesk 800 G2 DM
I have one desktop mini PC and it has M.2 nvme slot.
I bought ADT M.2 - PCIE connector (50CM) and asus gtx 1660ti card.
Everything went fine, I followed instructions you guys had already done.
After installed drivers and reboot, I found the external screen will "FREEZE" randomly, also the whole system will "REBOOT" suddenly.
At first I thought it may be caused by LTSC version, then I used another HDD, installed win7 sp1 and fully updated to the latest patch.
System won't "REBOOT" suddenly but "FREEZE" problem still exists.
Here's system summary:
- HP elitedesk 800 G2 DM 35W
- Q170 chipset
- I7-6700 (upgraded from 6700T by shorting PWM&RPM on HDD fan connector)
- 2x 8GB DDR4 2133MHz
- 256GB SATA SSD
- win10 x64 Enterprise LTSC
- ADT R43SG M.2 - PCIE connector 50CM
- ASUS ROG GTX1660TI A6G GAMING
- 450W ATX power supply
- a TV with HDMI used for external screen
Test PC Setup
- ASUS P8H67-V REV 3.0 (has PCIE 2.0 X16 slot)
- 2x 4GB DDR3 1333MHz
- win7 x64 SP1
- normal PC screen with HDMI
Bought one NVME SSD for testing M.2 slot
- ACER VT500M 512GB M.2 NVME
Set up video
Detected in BIOS
Card on test PC and test results, PCIE 2.0 X16, everything went smoothly.
Card on desktop mini test results, speed is unstable, PCIE 3.0 X4
NVME SSD speed test on same M.2 slot PCIE 3.0 X4
I tried to use another empty SATA HDD, installed WIN7 SP1 on mini PC, fully updated to lastest patch, "FREEZE" problem still exists.
Have described this issue with ADT Shanghai, they said it may be caused by harness issue and it will cause failure retransmission.
I will send it back for further investigate.
I live in Shanghai, hope it will be quick.
AIDA64 low write performance shows link errors between the system and eGPU. Suggest to try in order:
1. Another R43SG in case yours is faulty, including a shorter cable version. Your Shanghai proximity to ADT-Link means can get this step done quickly.
2. Another video card in case there is impedance mismatch causing link errors.
3. Find a BIOS/UEFI NVME slot link speed option to downgrade to slower, but more reliable Gen2/Gen1.
Did you remember to upgrade your computers power supply to the 90W version after you upgraded your CPU to the 6700? Because that CPU draws 65W, and thus max out your original power supply on its own (since that comp comes with the 65W version).
I have the same computer (800 G2 DM), but with the i5 processor.
How did you manage to detect the NVIDIA card in BIOS? I cannot find the correct configuration in BIOS.
Also I can't see this section on my BIOS:
Can you help me?
Thanks in advance.
