Optiplex 320 runs a Core2Duo e6700 with 1066mhz FSB

In case anyone is wondering whether you can upgrade your Optiplex 320 to a 1066mhz FSB Core2Duo -- it appears the answer is yes!  The e6700 is a 2.66ghz Core2Duo with a 4mb L2 cache -- Conroe.  Bios reports the CPU type and speed accurately, and the machine booted Windows XP just fine.  System control panel also reports speed accurately.

I had flashed the bios with 1.1.12, before trying the new cpu.  I've also tried  an e2180 (2ghz Pentium Dual Core with 1mb L2 cache) -- no surprise that it worked fine as well, but the e2180 uses an 800mhz FSB, which I had thought was the limit.

According to various articles on the ATI Xpress 200 chipset, however -- it appears it can support the higher speed Core 2 Duo cpus.

In a few minutes I'm going to try an e6500, which is a 2.93ghz Wolfdale Pentium Dual Core.  Will let you know if that works...

An E6300 Conroe is a reasonably quick CPU that is up to the task of Photoshop.

On my own optiplex 320 with P4 at 3.2Ghz (original one) 3Go ram and ATI 5770, I used to have win7 pro, with photoshop, illustrator, indesign, autocad, archicad, ... I don't know what you call a big file, but i used to work on A0 at 450 dpi, with dozens of layers.

The one thing to be change on this PC could be the Hard disk speed, wich was the problem. But now with SSDs! Moreover, it has been said that the proc could be overcloked to something like 3.6 or even 3.8, so no, you can expect it a lot more than only a

simple web browsing and Microsoft Office programs.

could be sometimes a higher frequencies mono proc be faster than a multicore with lower frequencies...

I paid $5 for my E6300, and it will outperform any P4. And you're right that an SSD would eliminate the IO bottleneck caused by slow hard drives.

Can someone suggest steps to take to get the bios 1.1.12 or newer to put the duo 2 core E6700 processor in my dell optiplex 320 CU395 motherboard........can I do a bios flash or update over the operating system Xp may upgrade that also.

I'm going to dells web site for driver downloads........maybe there'll be step by step instruction on flashing the bios.

I think that you propably have optiplex 330 not 320

optiplex 320 ISNT optiplex 330

they have a different chipset !!! (AIT versus Intel)

I have Optiplex 320 with e4400 and it works normally

I have used C2D E6600 (conroe)

it works and in BIOS OK

but i tested it inWXP with CPUZ and i found that FSB is ONLY 800MHZ

How can i solve my problem? is there a newer BIO then 1.1.12 ?

Is there a newer BIOS from ATI direct ?
