Upgrading CPU & RAM on a HP All in One

I own a HP All in One from Q3-2010. It uses a Core i3 550 - 3.2 GHz dual core processor with 2x 2GB RAM (1333 DDR3) on a A57 chipset based mother board (LGA 1156). The display is Nvidia GeForce GT 230. It comes with a 180W power supply. It runs on Win 7 - Home Premium (64bit). I have used it for general purpose computing and have been running Matlab 2008 on it.

From the documentation, I notice that I can upgrade to a Core i7 860 or 870 processor and to 2 x 4 GB RAM. The upgrade would cost around $310.

I have the following queries.

1. How long a typical MB on a branded AIO last. I have seen that typically my laptops (Dell, IBM, HP) have seen around 6-7 years with similar usage.

2. Does the upgrade at $310 make sense. Would that significantly improve processing capability.

3. Can 180w power supply handle the upgrade. I see the new processor uses 22W more than the current processor. Or should I need to upgrade the power supply too.

Thanks for support.

That's probably wisest. In the normal run of things I'd not advise people to upgrade things like Notebooks, Laptops and AIOs. They're just too precisely engineered with very limited tolerance and headroom.

Probably as long as a laptop or longer, and no it would not be worth it, is there any reason you want a all in one? They're pretty terrible unless you're in a situation where it's needed.

I must disagree with the previous poster. If you already own the AIO, and need more muscle to handle Mathlab tasks, then the $310 upgrade would make sense. I would imagine that the 22W additional power can be handled within the tolerance of the original build. If you order the upgrade from the OEM IHP) Check with them.

310 is outrageous for a chip that old, microcenter is selling the new haswell-e six core for $300, even with labor that is just a ridiculous price. If anything buy one elsewhere and get the labor done locally.
You'd also have to consider the extra heat this cpu will generate in such a closed case, Idk if the current cooler would be enough.

Thanks for the replies.
I bought the AIO when my kiddo was a year old and it gave me clutter free area, as we were worried that she might pull a wire or two.

CPU costs around $220 + RAM is $80 and shipping is $10. I also see used processors at $80 on eBay.

Heat could be an issue. Even now it generates significant heat when I run Matlab.

You can open Resource monitor and see if your RAM is over-committed. If there is lots of paging, etc. then a RAM upgrade may well speed things up.

When I see the "Task Manager", I see memory usage at between 2.9 - 3.1GB when Matlab is running

Thanks a ton.

Will do it tomorrow when I run the program.

The information that I provided (2.9 - 3.1 GB) was from the second picture. The CPU shows around 35% +/-5% when I ran Matlab last time.

Will check details of first pic tomorrow and post the pics as well. Thanks again.

I ran a few checks on the AIO today.

It uses around 1.2 GB RAM with no applications running.

I loaded apps sequentially to check RAM usage.

IBroker TWS (Java Based) : RAM usage moved to around 1.6GB
Trading Utility of an Indian Broker : RAM usage moved to around 1.75GB
Mozilla Firefox : RAM usage moved to around 2.1 GB
Matlab : RAM usage moved to around 2.6GB

Installed HWMonitor to check the CPU temperature. Average was 53 deg C and max was 61 deg C.

Now I'm more worried about upgrading as i7 processor uses 20W more power and I think that could mean higher CPU temp too - Is that right?

Should I just leave the AIO the way it is rather than looking to upgrade?

I ran a temperature check utility - HWmonitor today. The core temperature was around 52deg C. It worries me to upgrade now.
