CPU Upgrade

Jump to solution

I have a Dell 0NWWY0 motherboard with a AMD Athlon II X4 640 CPU Chipset AMD 785G.  I am wondering if it is possible to upgrade the CPU to an AMD Phenom II X6?  If so is the performance increase worth the price?

You have a STUDIO XPS 7100  Just Giving part numbers is too little information for most.

We are users not Dell Engineering.

Motherboard 0NWWY0 A00

Chipset: AMD 785G

Southbridge: AMD SB700

LPCIO: ITE IT8721

I believe it will take 6-core AMD 1055T

AMD Phenom II X6 1055T Thuban 2.8GHz Socket AM3 125W Six-Core Desktop Processor HDT55TFBGRBOX

I believe it also supports quad-core AMD Athlon and Phenom II processors and  Athlon II x4 630.

CURRENT BIOS IS HIGHLY RECOMMENDED BEFORE changing processor.

Chris M may have a list of Validated Processors for this system.

Should be installed as Administrator with ANTIVIRUS SOFTWARE UNINSTALLED.

Some antivirus software crashes the bios update and kills the system before it can be upgraded.

Reinstall Antivirus software after Bios update.

Thanks.  I do indeed have a XPS 7100.  I will upgrade the BIOS and try a Phenom II X61075 on the MB.  I well also disable my anti-virus software (MS Security Essentials)  prior to the BIOS upgrade.

I saw that.  Amazon sent me an e-mail because I had been looking at fans for AMD CPU's.  The price on that one got me considering an upgrade.  

I am unsure that it will give me a significant performance boost.

@SpeedStep: I just wondering regarding Inspiron 570 capabilities, because my chipset is also 785G, Southbridge also SB700, only LPCIO is IT8720 not IT8721, is it also can hypothetically support X6 similar family processors?

Just curious.

According to CPU benchmark Athlon II X4 640 average CPU benchmark is 3357, mine Phenom II x4 965 BE (not overclocked) average CPU benchmark is 4303, and AMD Phenom II X6 1045T average CPU benchmark is 4854 - it will make a noticeable difference for you, maybe not huge, but still a difference.

I think I will do the upgrade to the Phenom II, which has a L3 cache that my Athlon does not.

Do not upgrade the cpu. It is the worse hardware attempt to make. The computer will probably not even start after you do. Trust what I am telling you.

With 965 BE you most likely can even overcklock you XPS!
