Welcome to our HP Community forum!
As far as I was able to ascertain (legacy HP information is unfortunately spotty at best) your HP Pavilion 23-b1026cx All-in-One uses an LGA 1155 socket motherboard (HP part number 696941-001 / 700544-601) based on the Intel H61 Express chipset. This means it supports 2nd Gen (Sandy Bridge) and 3rd Gen (Ivy Bridge) Intel desktop processors with TDP of 65W or less -as it's an all-in-one system with limited cooling.
The good news is that you can upgrade the processor in your HP Pavilion 23-b1026cx All-in-One, and here's a detailed breakdown to guide your expectations:
Upgradeability:
The CPU is socketed (not soldered), using LGA 1155 (Socket H2).
It supports 2nd-Gen (Sandy Bridge) and 3rd-Gen (Ivy Bridge) Intel Core desktop CPUs.
Swapping the processor is physically possible and supported by the motherboard and BIOS.
System Details:
Motherboard: IPISB-NK (a.k.a. Lavaca3-SB)
Chipset: Intel H61 Express
CPU socket: LGA 1155
Likely Stock CPU: Intel Core i3-3220T (Ivy Bridge, 35W TDP)
Compatible Processor Families:
2nd Gen Intel Core (Sandy Bridge)
3rd Gen Intel Core (Ivy Bridge)
CPU must match the following:
Socket: LGA 1155
TDP: Preferably ≤65W (to stay within thermal limits)
Chipset: Intel H61-compatible CPUs only
Recommended CPUs (Safe Options):
i5-3470S | 4 / 4 | 65W | Ivy Bridge – great upgrade |
i5-3570S | 4 / 4 | 65W | Slightly faster Ivy Bridge |
i7-3770S | 4 / 8 | 65W | Ivy Bridge – top-end upgrade |
i3-3240 | 2 / 4 | 55W | Good if budget is tight |
i5-2400S | 4 / 4 | 65W | Sandy Bridge alternative |
i7-2600S | 4 / 8 | 65W | Sandy Bridge top-tier |
