Success: Dell Wyse 5470 running stable with 12GB RAM (official limit is 8GB)
Hey everyone,
I wanted to share my experience with a RAM upgrade on the Dell Wyse 5470. As we all know, Dell officially specifies a maximum of 8GB.
I decided to take a risk and test the 8GB limit. My device is now running completely stable with 12GB! The system boots without any issues and shows no errors under load.
My configuration:
- Device: Dell Wyse 5470 (Thin Client)
- CPU: Intel Celeron N4100 @ 1.10GHz
- BIOS version: 1.34.0
- OS: Debian 13 ("Trixie")
RAM configuration:
| Slot | Size | Manufacturer | Part Number | Spec |
|---|---|---|---|---|
| ChannelA-DIMM1 | 8 GB | Samsung (80CE) | M471A1G44BB0-CWE |
DDR4-3200 (runs at 2400) |
| ChannelA-DIMM2 | 4 GB | Micron (802C) | 4ATF51264HZ-3G2J1 |
DDR4-3200 (runs at 2400) |
Proof (dmidecode):
Size: 8 GB
Locator: ChannelA-DIMM1
Type: DDR4
Speed: 3200 MT/s
Manufacturer: 80CE000080CE
Part Number: M471A1G44BB0-CWE
Configured Memory Speed: 2400 MT/s
Size: 4 GB
Locator: ChannelA-DIMM2
Type: DDR4
Speed: 3200 MT/s
Manufacturer: 802C0000802C
Part Number: 4ATF51264HZ-3G2J1
Configured Memory Speed: 2400 MT/s
System recognizes all 12GB (free -h):
total: 11Gi, used: 2.8Gi, free: 7.8Gi, available: 8.7Gi
My observations:
- Both modules are rated for 3200 MT/s but run at 2400 MT/s - this is normal for the N4100.
- The configuration is asymmetric (8GB + 4GB). The system is likely running in Flex Mode: 8GB (4+4) in dual-channel, the remaining 4GB in single-channel.
- BIOS version 1.34.0 seems to have no issues with this mixed configuration.
Conclusion: The 8GB limit on the Wyse 5470 isn't set in stone. With the right combination (here: 8GB + 4GB), 12GB is achievable.
Question for the community:
Has anyone tested a 16GB stick in a Wyse 5470 yet? In theory, that would enable 20GB or 24GB (8+16 or 4+16).
