Upgrading CPU on XPS 625
I have XPS 625 which originally came with AMD Athlon X2 5600+ Black Edition AM2 CPU. I recently made a purchase of AMD Phenom II X4 940 Black Edition AM2+ CPU. I did everything I could to research if my XPS 625 supported this CPU. I've checked with my motherboard instruction as well and it said Phenom II X4 was supported. I have also read here on the forum that it can be done also. When I installed this processor, I followed all instructions as to how to install. But once I turn on the computer, I come up with no screen. I've also noticed there are no power to my keyboard either but the Alienware LED light does come on but with default white color. I hear my computer but nothing else is happening. This is actually my 2nd Phenom processor I purchased and both were brand new. I was hoping if anyone could help me on this.
Here is my computer dxdiag specs. Thanks in advance. :emotion-1:

Hi sandiego92139,
The system is working fine, there seems to be an issue with the monitor. I would like you to disconnect the cable from the CPU and check if the monitor performs the self-test.
Also, I would like you to select the correct input source on the monitor.

helow ravi,
thanks for your prompt response. with regards to your queries, 1st,the power button lits and remains solid after you turn on. 2nd, no unusual beeps whatsoever that i heard of except for the fans working.
the monitor is working perfectly fine and just when i started to assemble the unit again to their new home that i encountered this blank screen. either the analog nor the digital connection cannot be detected.
hope you can help me on this.
thanks.
I am working right now at Toms hardware on upgrading XPS 625 here, and I found confirmation for Chris, (well, it is not what I was thinking, it is not retail one, oops) and another one, here Ebay link to XPS 625 motherboard with Phenom II X4 940 Black Edition, (this one could be be retaile according to seller, but I might be wrong) so it makes 2 different confirmations, I think.
If I am right, this is very serious upgrade!!!:emotion-14:

Hi Chris,
I know this is an old thread but I had to ask a question about your reply. Like the OP I am wanting to upgrade my 625 to a quad core processor and based on your answers I searched the dell website for any AMD Phenom processors and came up empty. I see the OP purchased a retail Phenom II - do we have to purchase Dell's version in order for it to work? If so, where can these be purchased since I cannot find it on the website?
Thanks and sorry to bring up an old post.

Hi sandiego92139,
Dell XPS 625 comes with diagnostic indicators. If the computer is not starting up you can refer to the diagnostic indicators.
First I’d like to know The Dell XPS 625 power button light located on the front of the computer illuminates and blinks or remains solid.
Second I’d like to know if you are getting any beep codes. The Dell XPS 625 system can emit a series of beeps during start-up if the display cannot show errors or problems. These series of beeps, called beep codes, identify various problems. Please let me know how many beeps you get.
Please reply so that we could assist you further.
