Optiplex 745 3.2 P4 cpu

Hello,
I have a optiplex 745 with a 3.2 P4 - 800fsb. I want to upgrade.......I looked on here and thought I found that I could use a E6700 - 1066fsb 3.2 dual core but, it would boot, I tried a E5400 2.7 dual - 800fsb and still won't boot, all they do is put the case fan at full speed, I pulled the cmos battery thinking it would reset, and the same....
Any Ideas (other that scraping my company pc)?
Thanks for any input

I'm confused. Show you what? That a Q6600 works in a Optiplex 745? Unfortunately my parents in-law have the computer now but I assure you that it does work. It's a 65nm CPU which the Optiplex 745 motherboard supports.

Well, I apologize since I don't have the computer anymore but here's a thread from Dell about a person who did the same thing:

Are you saying it won't work? It was a G0 stepping if that matters and I believe BIOS version 2.4.1 which I think is not the latest.

true.
I should have rephrased it.
Try this:
do you know the BIOS update in particular that allowed the Optiplex to run a wider variety of chips and,
what exactly did the BIOS update change to allow such an improvement.?
how's that.? :whistle: 

Thanks.
Ahh, ok. That makes sense. I think I do remember reading about one of the BIOS updates (2.3.1?) expanding support for more CPUs. Thanks.

it can but it's not overly known..

From what I can tell, that Dell uses the old Q965 chipset (see: http://www.dell.com/downloads/global/products/optix/en/... ). AFAIK, that chip set do not support 45nm CPUs.

See: http://www.intel.com/products/desktop/chipsets/q965-q96...
Notice that the FSB supported is maxed out at 1066. Which would mean that 45nm CPUs are probably not supported.
And : http://bit.ly/cipUic
And finally, the CPU support page do not list any 45nm CPU as being supported (look under COMPATIBLE PRODUCTS > Compatible CPUs): http://ark.intel.com/chipset.aspx?familyID=22756
It also do not list C2Q support, even the 65nm varient. So you may not be able to run a c2Q on this chipset.


Unless you can show me a CPUZ validated link, I'm gonna say that 45nm CPUs won't work on that board/chipset. 65nm C2Qs may or may not work.

OK, updated the bios yesterday, with 2.6.4 - 3/16/2010, I think it had 2.4.x from 6/2006. I installed the e6700, no dice. I pulled the batttery, no dice. So I guess I could buy a Q6600 on ebay but, errrr to risky.
Thanks for all the input, you have all bee very helpful.

On another note would flashing the bios to a dell with the 65nm work?
I won't do that to this one, my boss would not be happy if it died.

Looks like Dell uses some locked BIOS to limit CPU models. Sorry, looks like you are SOL. A Q6600 WILL NOT work with that chipset. (See my above post).

The E6700 should have worked, but by the looks of it, either the CPU is dead or Dell has a locked BIOS that limits it to certain CPU models.
