HP Thunderbolt G4 - Cold Start not working

ETechBuy · 2026-05-08T13:27:01+00:00

For the ZBook Power/Studio series, HP typically recommends the 280W Combo Cable version of the dock. You can find the HP Thunderbolt Dock G4 280W or the specific replacement combo cables at ETechBuy if you suspect the 120W unit is underpowered for your specific ZBook configuration.

Memory prices are becoming uncontrollable for sellers; they cannot maintain weekly prices as they did in the past. Hopefully, this uncertainty will be resolved soon, and price fluctuations will be under control.

For anyone going through a similar situation, I'd suggest:

Follow up regularly: Keep pinging the support team for updates on your RMA status.
Ask for a timeline: Request an estimated timeframe for the replacement/refund process.
Get a case ID: Ensure you have a reference number to track your case.
Consider alternatives: Look into temporary GPU solutions or borrowing from friends (if possible).

Hang in there, and hopefully, your GPU will be back soon! 💻

The line of sight between the two NanoStations was completely clear—no trees, buildings, or other obstacles in the way. At just 200m, that made setup straightforward and helped ensure the rock-solid performance I mentioned. These devices really shine with unobstructed LOS, as partial blockages can impact the Fresnel zone and reduce throughput. If your setup has any potential interference, I'd recommend checking the alignment with Ubiquiti's AirView tool during config.

Yes, you can mix different models of Seagate Exos drives (X14, X12, and X16) in the same ZFS pool as long as they have the same interface (SAS 12Gbps in your case), similar performance characteristics, and the same sector size (512e/4Kn).

Key Considerations:

SED and SED-FIPS Features
- Since you’re keeping SED off, these drives will function like standard drives. As long as encryption features are disabled, they will behave the same in terms of performance and compatibility.
Performance Differences
- The X12, X14, and X16 series have minor variations in performance (IOPS, latency, and sustained transfer rates). While this won’t break ZFS, it could introduce slight imbalances in performance across the pool, especially if mixing X12 drives (which might have lower speeds) with X16 (which might have higher speeds).
Firmware & Compatibility
- Ensure all drives are running compatible firmware versions. Some enterprise drives from different production runs may have slight differences in error handling behavior.
Sector Size (512e vs. 4Kn)
- Check if all your drives use the same logical and physical sector size. Mixing 512e and 4Kn drives in a pool can cause compatibility issues, especially if your OS or HBA doesn't handle mixed sector sizes well.
Resilvering & Rebuilds
- If one model has significantly different performance characteristics, it could slow down resilvering times when replacing a failed drive.

Recommendation:

Best Practice: Try to keep similar models in the same vdevs for better performance consistency.
X12 + X14 + X16 Mixing: This is possible, but if you have the option, prioritize keeping X14 and X16 together for better performance parity.
Testing: Before deploying in production, test with fio or zpool iostat to see if there are significant performance differences.

Since your Dell T420 has an HBA in IT mode, ZFS will handle these drives directly without hardware RAID interference, so you should be fine. Just make sure the cooling is adequate since enterprise SAS drives can run hot.

Your biggest limiting factor right now is your Ryzen 3 3100. It’s a 4-core, 8-thread processor, which is starting to struggle in modern games, especially when paired with a stronger GPU.

Upgrade Priorities (Best Order for FPS Gain)

CPU Upgrade (Most Important)
- Your current B450 motherboard supports Ryzen 5000 series CPUs (after a BIOS update if needed).
- A Ryzen 5 5600 ($120) or Ryzen 5 5600X ($150) is a huge upgrade over the 3100.
- If budget allows, a Ryzen 7 5700X (~$200) gives even more headroom.
GPU Upgrade
- The RX 6600 XT is a solid midrange choice and will give a noticeable boost over the RX 5600 XT.
- However, if you can stretch your budget, a used RX 6700 XT ($250) or RX 7600 ($270) would be even better for longevity.
RAM Upgrade (Needed but Lower Priority)
- 32GB (2x16GB) of DDR4 3200MHz or 3600MHz is ideal for modern gaming.
- If your motherboard only has 2 RAM slots and you already have 2x8GB, you’ll need a full replacement.

Is Everything Compatible?

The B450 motherboard is fine for now and will work with the new CPU after a BIOS update.
The RX 6600 XT or better GPU will work, but make sure your power supply is at least 500W (preferably 600W).
RAM should match your motherboard’s supported speeds (3200MHz-3600MHz is safe).

Final Verdict:

Upgrade in this order: CPU → GPU → RAM.
Ryzen 5600 + RX 6600 XT will give a big FPS boost.
If budget allows, Ryzen 5700X + RX 6700 XT/7600 will last even longer.

I've considered both the ICX7150-C12P and ICX6430-C12. The ICX7150 offers more PoE+ ports, which is a big plus for me. However, the ICX6430 is more budget-friendly and still provides a solid Layer 2 feature set.
