Upgrading my XPS 435mt CPU

Jump to solution

Does anyone know if the processor on the XPS 435mt (bought in 2010) can be upgraded to a newer i7 3rd generation processor - or whether the motherboard would be able to accept anything newer than the 2.67Ghz I have on the board now -- it has slowed way down and I thought buying an i7 would at least keep me going for a few years.......?  Any ideas or suggestions?  If I have to replace the motherboard to upgrade the processor - has anyone attempted this with success?  What motherboard have you had success with.  I am using the computer primarily for video editing of home movies.... and some internet surfing ---just seems like it has really slowed down... thanks

Sorry to revive an old topic but I'm also wanting to upgrade my cpu from the 920 to the 965 (as listed above). Would this be simply a plug-and play exchange with nothing more to do? Well, after a BIOS update? And I'd love to transfer everything to a new, larger case.

Yes.

But, prior to installing the new processor, check that the latest BIOS version is installed.

When a heatsink or processor is removed, replaced, or reused, it is advisable to clean them both and reapply a thermal compound, as directed.

Directions for cleaning and applying thermal compound, are HERE.

Only a small tube of thermal compound is required, this can be purchased from any online, or local computer store.

According to my System Information, I have the latest BIOS update (1.1.4) already installed. So I assume I'm ready to go.

Thanks so much for taking the time to reply and for the tip on the thermal compound.

Have a happy new year!

EDIT: I see the 1.1.4 BIOS update was updated in Nov 2011. I believe I updated my BIOS before that update. So, I guess I'll need to do another update.

To bring this thread up-to-date, the fastest i7-9xx processors that are upgrade options for the Dell Studio XPS 435MT (Mini Tower) are (all quad core):

  • i7-975, 3.33 GHz
  • i7-965, 3.2 GHz
  • i7-960, 3.2 GHz

Matching Xeon processors also work and are usually less expensive:

  • W3580, 3.33 GHz
  • W3570, 3.2 GHz
  • W3565 3.2 GHz

Note that neither 6 core i7-9xx processors nor 6 core Xeons work in the 435MT.  Hex core Gulftown i7-990X, i7-980X, i7-980 and i7-970 processors will not work since 435MT BIOS wasn't updated to support them.

See this discussion thread for more details.
