Question: Will this work with a Dell Dimension E520?
Document: An older Dell was upgraded and it works great. One negative though is the heatsink/fan assembly does not fit the Dell motherboard and the package did not contain thermal grease. I would have ordered the thermal grease if I knew I had to reuse the Dell heat sink assembly.
This CPU certainly will work for 75% of the non-gaming population. My Windows 7 build is 8GB RAM, SSD for C: (which has OS), mirrored Western Digital  E: drive for non-OS stuff, and the video card (of all things) is the bottle-neck according to the idiotic Microsoft benchmark. I don't &#34;do&#34; games, so I don't care about video performance.
This is an excellent cpu. I have a Gigabyte EP45-UD3L motherboard and it overclocks so easily on air. I have it running at 4.18GHz with 440MHz bus speed voltage upped to 1.45V. Runs stable and fast. I had no intention of overclocking it when i got it. Just a work computer that is occasionally used for games, video etc. Temperatures were so low using Coolermaster Hyper n520 (25C/45C) that I decided to try overclocking.
this processor is very fast and easy to install. I changed from the Quad core Q6600 to this unit and I'm much happier with it.
great up grade for my slim line pc.i had to use my original fan,, so the fan that came with it is still in the box.which is ok , because the original cooling fins are bigger.
considering what i payed verses proformance this was a good buy. The chip rocks for a 775 socket chip. hard to find much fault here.
a very good processor ..i love it , no lagging---> need a good heat sink..........dont use the one that comes with the box.....excelente procesador,,, muy bueno y rapido ( necesita un buen disipador de calor ,, no usen el que viene en la caja (incluido )es muy barato. ....muy muy bueno el procesador.
Wow - absolutely exceeded my expectations for performance. I needed an inexpensive upgrade for my mom's Inspiron 630S, and this was an easy, yet dramatic improvement. She's been using it for about a month now with no problems at all.
Works good, my first socket 775 intel computer build. Installed windows 8 on this system also with 4 gigs of ram.It's pretty snappy fast.
With these cautions, you will have a blazing fast system that is in a moderate price range.
Answer: I doesn't appear so.  From a Dell Support forum page:" . . . only 65 nm processors with 800 or 1066fsb will work with the E-520. [FSB refers to the bus the CPU uses for external communications and 800fsb and 1066 fsb refer to the bus' bandwidths] The following is a list of supported processors, using BIOS version 2.4.0Conroe, E6400, 2.13GConroe, E6700, 2.66GConroe, E6300, 1.86GConroe, E6600, 2.4GPrescott P4, 541, 3.2GPrescott P4, 524, 3.06GPrescott Celeron, 351Prescott Celeron, 346Prescott Celeron, 336Prescott P4, 531, 3.0GPresler P4, 940, 3.2GPresler P4, 945, 3.4GPresler P4, 930, 3.0GPresler P4, 925, 3.0GPresler P4, 950, 3.4GCedar Mill, 661, 3.6GCedar Mill, 651, 3.4GCedar Mill, 641, 3.2GCedar Mill, 631, 3.0GPlus the Q6600 and possibly the Q6700."See this Wikipedia page for information about the Intel Core 2 Duo processors and what these code names refer to . . . https://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors
