How To Upgrade HP Z2 Mini G4: CPU & GPU Compatibility Tips

Select Language:

If you’re like me and own an older PC, upgrading can give it a whole new life. I have a Z2 Mini G4, and I want to make it faster and more capable. Here’s a simple guide on how to upgrade the CPU and GPU without much hassle.

For the CPU, since my Z2 Mini G4 is the high-performance version, it supports most Intel Core 8th and 9th generation processors, including some Xeon E-series chips. I’m considering upgrading to the Xeon E-2288G, which has a TDP of 95W. This seems doable because the system can also handle i7 K-series or even i9 K-series CPUs, although heat might become an issue with more powerful processors. When upgrading, keep in mind that the BIOS may have a whitelist that only allows certain CPUs. I looked into this but couldn’t find any clear info in the BIOS or online, so proceed with caution.

Now, about the GPU, this part is exciting. The official support page states that the PC can handle a maximum GPU like the P1000. However, many users on Reddit have installed much more powerful graphics cards such as the T1000 or RTX A3000, which are MXM Type-A cards with TDPs of around 50-75W. I even saw posts where people managed to install a Titan X, which isn’t MXM but connected via the M.2 expansion slot.

I’m considering taking a risk and installing an RTX 4070M MXM Type-A card, as some enthusiasts have tested it successfully. Still, I worry the HP whitelist might block it, preventing the card from working properly. If the whitelist is in place, it could reject new cards, making the upgrade impossible.

I’ve loved my Z2 Mini G4 for about three years now and want to extend its life as much as I can. If you’re thinking of upgrading yours, I suggest doing thorough research first. Check online forums, Reddit, and YouTube for real user experiences. Be cautious about BIOS restrictions, and know that some upgrades may involve risks, but the rewards can be worth it.

Thanks for reading and good luck with your upgrade journey! Hope your PC becomes faster and more capable for years to come.
