HP Pavilion All-in-One 24-xa0xxx CPU Upgrade

[bzzarr1014]

I am currently using a HP Pavilion All-in-One 24-xa0xxx with an i7-9700T CPU and I was wondering if it is possible to upgrade the CPU and what are some good upgrade options to consider. In addition, I'd just like to request a couple tips on what components I can replace for a better performance when it comes to handling tasks such as gaming and video editing.

I've also gone to an AI and inputted the question, are these possible upgrades that are compatible?

@bzzarr1014, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Based on your system info (HP Pavilion All-in-One 24-xa0xxx with an Intel Core i7-9700T), here's a realistic and technical overview of CPU upgrade options and overall system upgrade paths:

CPU Upgrade Considerations

Your HP Pavilion All-in-One 24-xa0171hk uses an Intel 9th Gen i7-9700T on an LGA 1151 socket motherboard, likely with a chipset such as Intel H370/B360/Q370. However, as this is an OEM all-in-one PC, your upgrade options are severely limited due to:

• Proprietary motherboard and BIOS – May not support CPUs outside what HP originally validated.
• Thermal design constraints – Compact all-in-one cooling is not meant for high TDP CPUs.
• Power delivery limits – Some PSUs in AIOs can’t handle more demanding chips.

Likely CPU Upgrade Options:

Intel Core i7-9700 (non-T) – Slightly better performance than the 9700T (65W vs 35W TDP). May work if the cooling can handle it.

Intel Core i9-9900T – Same 35W TDP as your current CPU but with 8 cores/16 threads. Best balance of performance + compatibility.

Intel Core i9-9900 (non-T) – Offers top-tier 9th Gen performance, but may not be compatible due to TDP (65W) and BIOS.

10th Gen CPUs (like i7-10700T) – Not compatible. Different socket (LGA 1200) and chipset.

The suggestion in the AI reply about i7-10700T or i7-11700T is incorrect for your system. They use LGA 1200, not LGA 1151, and your motherboard will not support them.

Other Performance Upgrade Tips

Since CPU upgrades are constrained, here are better and safer ways to improve performance for gaming and video editing:

RAM

• You're already using 16 GB, which is decent.
• Make sure it's running in dual-channel mode (check in Task Manager > Performance > Memory).
• You can upgrade to 32 GB (2×16 GB, DDR4-2666) if doing video editing with large files.

Storage (High Impact)

• Upgrade to NVMe SSD (if not already). A 1TB NVMe SSD will drastically improve boot and load times.
• If you're still on a SATA SSD or HDD, this is the most impactful upgrade.

eGPU (External GPU)

• For gaming, consider an external GPU setup using a Thunderbolt or USB-C to PCIe eGPU dock (note: may need to check if your model supports it).
• Realistically, most AIOs don’t support eGPU well — verify if yours has Thunderbolt 3.

Undervolting or repasting CPU

• Reduce heat and slightly improve performance by undervolting the CPU or replacing the thermal paste.

I hope this helps. 

Take care and have a good day.
