Windows 7: Want to upgrade the processor in my HP Desktop Computer

Want to upgrade the processor in my HP Desktop Computer

Hi All,

I have a HP computer, which I want to upgrade the processor in. The model of the HP is an a6220a Desktop, specifications for it can be found here:

According to HP documentation I can upgrade as far as an Intel E4300, however my friend has just given me an E4400, the irony!!! Here is a link to the processor capabilities of my HP:

The processor is the right socket type, however there is a chance that the motherboard BIOS will not support the instruction set of the E4400!

I noticed that the motherboard is an ECS 945GCT-HM (Livermore8), and for all intents and purposes it looks like an ECS 945GCT-M (V1.0) - the only exception being that the "-M" has both an AGP and a PCIe Slot!

Would it be possilbe to use a BIOS upgrade from the ECS website if my HP struggles when I install the E4400?

Any advice will be greatly appreciated.

Kind Regards,

Hmm, tough one!

I tried to find more information beyond what you found out, maybe even a newer BIOS, but came up empty. Whether or not your E4400 will work is really hard to say.

What I can tell you is: it's worth a try. It won't be damaged even if the BIOS doesn't accept it; worst case you'll simply have to find an E4300 or go back to your current processor.

The other option - flashing your BIOS with one provided by ECS for the "M" (not "HM") motherboard - similarly may or may not work. But if it doesn't then you'll have bricked your system and be unable to ever get it working again unless you have some built-in BIOS recovery option.

A third option would be having an experienced person modify your existing BIOS and try to add support for CPUs beyond the E4300. I'm not sure if this is even possible, but I know of a forum where you can submit a request to have such a mod done. Of course, again this is completely at your own risk as you'll have to flash the modified BIOS on good faith that it'll work (they can't test it for you).

Out of curiosity, which CPU do you currently have installed?

Processor Upgrade?
I've not had a problem with my processor until now, because I've not been into anything all that processor intensive before. But now, I've found that working with video files which require a lot of encoding, runs my CPU at 100%. That is not a problem, except that I can't use the computer for...
