Will this CPU fit in my motherboard?

The motherboard I have is the one that came with my e521. It apparently has an AM2 socket and the only quad core I could find that might fit is the amd phenom ii x4 940 which can fit in an AM2+ socket. Before I actually purchase the processor, i'd like to make sure this processor will be able to fit in without problems. Can anyone confirm this? The reason for this is because my old cpu is bottlenecking my ati radeon 4850 and limiting my fps when it comes to gaming.
And also, is my 420 watt antec enough for both this processor and the ati radeon 4850?

UPDATE

I really want a nice processor, but I don't want to try to buy a new motherboard and install it, so I think i'm gonna go with this:

I'll just take 1gig of ram from my e521 and my ati radeon 4850 and put it in that. They're both ddr2, so it should work right? Or should I spend more for ddr3?

More about will motherboard
  1. What's your motherboard model? What's an e521? Your computer model? What's the vendor? HP? Dell? Need more info before we can confirm if that processor will work for you.
  2. Don't really know wt the model is. It is the one that came with my dell dimension e521. I'm pretty sure the cpu socket it has is AM2
  3. Is this your computer?

    If so, that's a AM2 socket, not a AM2+, which is what an Phenom II would need. So, no, that processor won't work with your mother board.
  4. "AMD confirmed that AM2 processors will work on AM2+ motherboards and AM2+ processors will work on AM2 motherboards. However, the operation of AM2+ processors on AM2 motherboards will be limited to the specifications of Socket AM2 (1 GHz HyperTransport 2.0, and one power plane for both cores and the IMC). AM2 processors do not benefit from the faster HyperTransport 3.0 and separate power planes on AM2+ motherboards."

    Care to explain? Im not too sure what that means.
  5. i just did some xtensive research on ur system, that board doesnt mension anything about am2+, i think you should besafe and get 1 of these

  6. I may be wrong (I'm more Intel knowledgeable), but he's wanting to use a Phenom II 940, which I understand needs a AM2+, at minimum, for a socket. I didn't think Phenom II's worked in AM2 sockets. His board is only AM2, not AM2+.

  8. I doubt that either that Dell's power supply or the voltage regulators on the motherboard could handle a Phenom II. I would go with a low power Brisbane but only after checking to see if it is on the motherboards cpu support list.

    Newegg has a 5600 X2 Brisbane for $55 that only draws 65w.

    In order for the memory to run in dual channel mode, it needs to be a matching kit in the slots. That board only has two slots for the RAM, so the memory you put in those two slots has to be matching. Is that true of your current 1GB of RAM?

    Your video card should work fine.
  10. The computer comes with 2gigs of ram, which I figured would go into the first slot, and the extra 1gig would go in the second. The first 2 gigs match, but the one from my e521 doesn't.
  11. You don't want to do that. The memory will only run in single channel mode, which is slower than dual channel. Try and pick a model that has 2GB as two 1GB sticks. You're not saving any real money by moving your old memory over.
  12. I actually do have 2 1gb sticks, but planned on only taking 1gb incase I wanted to use my old e521 again. But I guess i'll just go ahead and upgrade it to 4gb on the site.
  13. Good luck with the purchase!
