Which cpu will work

According to the HP support page, only AM2+ CPU upgrades are supported on that (proprietary) board, while the two CPUs listed use socket AM3. It also says the CPU that ships with the PC is AM3, which is a bit odd. To be on the safe side I'd go with the "safer" choice of an AM2+ CPU to be more certain of compatibility.

You can use neither of the two CPU's because they are socket AM3, whereas your motherboard is socket AM2+ and will only use socket AM2+ CPU's. The limit for your board is this CPU which is no longer sold.

When searching on newegg filter AM2+ socket on the left side when searching for CPU

i thought that am3 processors were able to work on am2+ mobos tho?

There's only one on newegg,which is a mediocre single core Sempron.

That's true only if the motherboard supports it, which unfortunately, yours does not.

that is what i didnt understand, i might just wing it but it would be a big waste of money because newegg dosent have a return policy on cpu's

I've seen a lot of am2+ motherboards that don't mention anything about am3 support but will run a am3 CPU.

But you have a proprietary motherboard so it could be different.

FYI am3+ definitely won't work

It really depends on the motherboard.
I have a biostar board that only supports Phenon2 940 and below cpus. A 955, 965 AM2+ processors will boot but the board then stops with a warning. Unknown CPU and will not boot any farther.
It all depends on bios support.

well looks like ill have to find one thats am2+ then. ive been looking tho and there hard to come by. Im mainly trying to upgrade my pc to run d3 smoothly

CPUWORLD. Look at the sockets. Does this means that the chips are supported by (some at least ) AM2+ boards?
