Pentium D to C2D in a dell?

post #1 of 13
Thread Starter 
A friend is trying to upgrade his Dell Dimension e520. its got a 2.8g pentium d. seeing as though its a socket 775, i suggested that he should upgrade to a C2D. his MB only supposts 800mhz FSB, so he cant go so far as a conroe- but an allendale should be a massive improvement over the pentium d that hes got in it. i ran super pi on his 2.8g pentium d, 46.6 seconds to 1M.

would an e4500, e4600 or e4700 processor be THAT big of a jump in performance?

Does the mobo support an E4x00 CPU?

EDIT: Meaning the Chipset!

it would depend on if his chipset would be able to support a C2D in the first place. Also, you wouldn't have to worry about FSB, because you can get more cache if he plays games

I looked into this and only certain revisions of the 945 chipset support the conroe. I dont know which one it would be, but I can tell you that the Dell motherboard out of a Dimension 700 with revision A00 will not support the conroe.

Just looked on Dells site....

Processor

Processor type


Intel® Pentium® 4
Intel® Pentium® D
Intel® Core™ 2 Duo

NOTE: Not all Pentium 4 processors support Hyper-Threading technology.

Level 1 (L1) cache


32 KB

Level 2 (L2) cache


1 MB for Pentium 4 5XX processors (with Hyper Threading)

2 MB for Pentium 4 6XX processors (with Hyper Threading)

2 x 2 MB for Pentium D 9XX processors (with dual core)

2 x 1 MB for Pentium D 8XX processors (with dual core)

256K for Celeron® D 3XX processors

2 MB for Intel Core™ E6400 processors and earlier

4 MB for Intel Core™ E6600 processors and later

EDIT: System clock


533-MHz, 800-MHz, or 1066-MHz data rate


Throw in a E6300 or something.

Those processors would be a massive jump in CPU performance, if they work. A stock E4700 will do between 21 and 23 seconds in SuperPI 1m, and will be around 50-100% faster than a 2.8GHz pentium D in most other tasks (where cpu is the limiting factor).

However, just because it's S775 is no guarantee of compatability. The board must be electrically compatable and have the appropriate BIOS as well.

Edit: according to Eric's info, it should work, but I would still be wary if it's an older machine. Dell has a nasty habit of reusing model numbers, so what he found may not be representative of what your friend has.

im not sure, thats kinda what i was looking to find out. from what ive read, his MB only supports up to 800mhz FSB. conroes are 1066+

im looking right now to see if i can the chipset on this board.
