Upgrading CPU in DELL 745

Hi,

I have a DELL - 745 with intel Pentium-D 925 3.0GHz/4M/800/05A.

I have two options of processor upgrade:

1- intel dual core 2.2GHz E2200 /1M/800
2- intel dual core 2.5GHz E5200

want to confirm

a) will they work in my motherboard?

b) is is a better upgrade to pentium-D ( if not considering core2 Duo option) ?


DELL specs available for 745 says in processor category:

from this link:
http://www.yale.edu/desktech/YAD/specs/OptiPlex745.pdf

-Intel® Core™ 2 Duo 1066MHz FSB Socket T with Dual Core technology XD, EM64T, 2MB and up to 4MB L2 cache, and EIST3 (E6000 series)


-Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x2MB L2 cache, and EIST3 (900 series)


-Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x1MB L2 cache (800series)


-Intel® Pentium® 4 800MHz FSB Socket T with HT, XD, EM64T, and 1MB L2 cache (500 series)


-Intel® Celeron® D 533 MHz FSB Socket T with XD and EM64T (300 series)





Please suggest

The E5200 is too new for that board so it won't work judging by the info you posted. You should check to see if there are any BIOS updates for that board that may increase CPU compatibility.

Thanks for respones


well I am sort of hurry on this matter, decide in a day or two

my available options are:

from Dual Core
E2200, E5200

and from Core 2 Duo
E6550, E6750

I did'nt find much help from Dell online docs on their site. except tech specs for DELL Optiplex 745

tech specs shows under 'processor'

(E6000 series)
-Intel® Core™ 2 Duo 1066MHz FSB Socket T with Dual Core technology XD, EM64T, 2MB and up to 4MB L2 cache, and EIST3

My options for E6000 series here:

E6550

Core 2 Duo E6550 SLA9X (G0) 2333 MHz 4 MB 1333 MT/s 7x 0.962 - 1.350 V 65 W LGA775



E6750
Core 2 Duo E6750 SLA9V (G0) 2667 MHz 4 MB 1333 MT/s 8x 0.962 - 1.350 V 65 W LGA775



--->Please note that in Dell specs mentioned in with Core 2 Duo option, 1066MHz FSB, while my both choices have 1333 MT/s.
it means to me CPU FSB rating is higher then Motherboard, so does that matter?

--->WILL E6550 OR E6750 WORK IN MY SYSTEM? HOW I VERIFY , these are boxed, seller is not responsible if they work or not after I purchase. No option to test first then purchase in this case.

and about E2200, E5200, they belong to Dual Core family, which is not mentioned in DELL specs, as u said quite sure they will work ( E2200 )

How do I confirm my BIOS/system will support these upgrades. MOBO is DELL part no. Chipset is Q946.


I think DELL does'nt allow any option for overclocking so that is out of consideration.


I appreciate your comments soon

THANKS
