Need help with CPU upgrade for Gateway DX4300-03

Grebnaws 77 10 July 24, 2012 at 11:16 PM
The cpu fan on my Gateway seized and burned out the Phenom x4 9750 2.4ghz.. I was able to beg a compatible cpu from a friend and function test the computer I am now typing from. Nothing appears to be damaged except this single core Athlon 64 1.8ghz ain't gonna cut it! I am at 100% cpu with just Win7 and Firefox.

I am not tech savvy and need time to order parts for my first DIY computer. In the meantime I would like to restore functionality and move this computer downstairs for use as a netflix/htpc downstairs.

What is the best cpu I can install on this machine? I am unaware of all the problems that could be associated with upgrading the processor. I would like a drop in solution to maximize what I've got and not spend money which would be better used for an upcoming build.

*EDIT* I wouldn't mind a higher clock speed dual/triple core cpu.

i doubt anyone can help without knowing what motherboard you have....

1) find out what mother board you have and what type of cpu socket it accepts
2) goto newegg or somewhere and search for cpus based on that socket type
3) select one that fits ur budget

Your version came with a first generation AMD Phenom X4 9750. There's no official CPU Support List from Gateway so you can't be sure what CPUs it will support. Gateway released other variants of this computer with a newer AMD Phenom II X4 805/810 CPU. From pictures at Newegg, they have the same exact motherboard. Also, Gateway's online support groups these two systems together and provides a single BIOS update that covers both systems. It is safe to assume that your DX4300-03 will support at least some Phenom II X4 CPUs.

At newegg, there are only two Phenom X4 choices left; the 955 and 965 models. These are from the same "Deneb []" series, but were leased a few months after the Phenom II X4 810, so they may not be included in the microcode of your BIOS.

First of all, make sure you update your BIOS to the latest one from Gateway support. You can then either give one of the processors mentioned above a try or if you want a safer bet, try to find a used Phenom II X4 805 or 810. You could also try a dual-core Athlon/Phenom since a quad core is overkill for an HTPC.

Your computer uses an AM2+ processor. You could also use an AM2 processor, which is backwards compatible. Hard to find those right now. AM2/AM2+ boards are "AM3 Ready" with a bios update.
Some say this model does not support AM3 processors.
This should work, but I can't guarantee it.

Please download CPU-Z and check the socket type, motherboard model and bios revision.
This will dispel any doubts we have.

This looks to be a 4 year old PC? Keep that in mind on your spending of a new CPU. It's not worth a a lot of $ to be putting into it.

This is really strange behavior and should not happen. I suspect you might have something else going on. You computer has several fail safes built in to prevent the CPU from getting too hot. It should restart automatically when it gets too hot. Most also have a check at post in the BIOS that will stop and or sound an alarm if the CPU fan is not turning. ADM also has their Quite and Cool technology that will slow the processor down a ton if it's too hot. I would check the BIOS to make sure you have these options turned on. I would also blow out the computer case and make sure the other fans are working. Is your ambient room temp high? Does the computer get good airflow (Not in a corner buried under a desk?)

Thank you all for the advice. It appears that the jury is still out on upgrading to Phenom II without official bios support, and it's not worth the investment when I'm so close to building a new one from scratch. My 2003 build running XP is a faster net box than this Gateway with a downgraded cpu. Time to start shopping in earnest for a new computer build.
