Upgrading CPU in DELL 745

mdimran1
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)


-----------------------After long wait------------


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
