Dimension E521 dual core processor up-grades

by bob5326 / June 30, 2010 8:55 PM PDT

I have a Dell Dimension E521, dual core, with AMD Athlon 64x2 dual core processor 3600+ 1.90GHz, running vista. My question is can I up-grade the processor itself or will I have to change the motherboard as well? And well the up-grade be noticeable or will I be wasting my time?

Can I be blunt?

After doing far too many upgrades I think you would be better off moving to Windows 7 than a CPU change. Other areas that pay off are RAM (get 2 to 4GB) and video cards since onboard video while nice enough for some things can be a bit sluggish.

There are other areas that will pay back more than a CPU change.

I forgot to mention that it has 2GB of ram and a Nvidia GeForce 8600 GT graphics card in it. I plan on up-grading to windows 7, but I still would like to up-grade the processor. Are you saying that I would not see an increase in speed?

Yes. I'll write that.

The CPU is just one small part of the speed puzzle.

Vista is sadly dogging this system and having changed a few too many I can write that easily that gave me back more than a change of a CPU that was 50% faster.

Remember you are still speed limited by video, hard drive and the rest of the system so any CPU speed increase usually results in an 1 to 2 % speed gain given we have to stick with the same board and more.

Why not go for what others have found give you double digit gains?

I don't agree that the processor is one small part of the speed process, I would say that is a part of the process. Everything that the computer does goes through the processor, a faster processor would do more then pick up a 1 or 2 per cent increase in speed. Granted, vista is like dragging bricks around when you're trying to swim, but my question still stands.

Let's see what others offer.

You can research on google what others have put into the CPU socket under discussion.

I do agreed sorry but one can't

The E521 is different from ATX form factor cases, motherboards and PSU, one can't upgrade this computer because it is BTX form factor. The BTX design is design defferently the ATX is much smaller one would not be able to fit the PSU into a ATX case and one won't be able to screw the motherboard into the chases. That's Dell !!! always looking for one best interest.

(NT) I thought BTX was Intel looking for our best interest?

I just upgraded my E521 from a 3500+ single core to a 6000+ (89W) dual core. She is working fine. With a 64 Bit Operating system (Win 7), she now takes 8 GB of Ram. Upgraded the PSU to 450 W. No Problem with the fit. The extra wattage on the cpu mean you want to add a couple of exhaust fans at the back. Perfect.

Seems only FOUR AM2 CPUs available at Newegg.

Eats links. But you can search at newegg for AM2 CPUs if you can't copy paste the link.

A couple years ago I installed a AMD 4800 processor in place of the 4200 that came with the computer and the only difference I could see was my wallet had a little less in it and I picked up a heat problem.
A new heatsink and fan took care of the heat problem, but it still didn't run much, if any faster than the old 4200.
No other hardware was changed.
