Fat Optiplex 760 CPU Upgrade?
Hello everyone, I am new to these forums. I have read other topics on this same subject, I am still unsure if I can upgrade my CPU.
I have the big fat Optiplex 760, not quite sure what you guys call it. I currently have the Core 2 Duo E8500 and I would like to upgrade to a Core 2 Quad processor. Someone said this "The 0M858N motherboard should support Core 2 Quad CPU's" and I have the 0M858N motherboard in my 760. Should I pull the trigger on purchasing a CPU upgrade for this PC? It looks like I can pick up a decent used quad core for around ~$25 - $60 through eBay or Amazon and a few other sites that popped up in a google search.

Can I do it? Is a Q series CPU out of the question for me and my computer? Any help is appreciated. Thanks.

The Optiplex 760MT Q43 Express Chipset uses two motherboards -
T674K Non-Quad core CPU motherboard
U562N Quad core CPU motherboard
U562N - Motherboard, Smith MT, Smith Bases P583N & P584N, TPM For Dell Optiplex 760
My Guess would be
SLB8W Q9650, 3 GHz, FSB 1333 MHz, L2 12 MB would be max once you have latest Bios Installed BEFORE changing CPU.

Other 760 Mini-Tower System Part Numbers: M858N, G214D
I would ask Chris M what the difference is.
If you have the 1st one so you cannot use a quad core CPU on it.
38G73 E7400, 2.8GHz, 3MB, WFD, R0, (With VT)
F31F5 E7500, 2.93GHz, 3MB, WFD, R0, (With VT)
06YMG Wolfdale Dual Core E7600, 3.06GHz, 3MB, 65W, R0, (With VT)
H399J Wolfdale Dual Core E8400, 3.0GHz, 6MB, 65W, E0, 1333FSB
D923J Wolfdale Dual Core E8500, 3.16GHz, 6MB, 65W, E0, 1333FSB
N654J Wolfdale Processor E8600, 3.33GHz

Just for future reference, the M858N board does support Intel Core 2 Quad processors. From what I've read it is the G214D board that does not. I purchased a Q9550 for my M858N and it booted right up and worked as intended. Recently I had an issue with some bent pins in the socket, my own fault from pulling the processor while I was cleaning out all the dust inside my machine, and I was researching the different boards for a replacement. I found the G214D is dual core only and can not be upgraded to a quad core. At least that's what I've found through my research online. I've placed an order for another used M858N board on eBay for $15 and I'll be back up and running by weeks end at the latest. This time I won't be bending any pins by mistake!
My curiosity might just lead my to purchasing a quad core Xeon LGA 771 and a 771 to 775 adapter just to see if it would work. I may be pushing my luck on this idea but if the LGA 775 Q9550 was able to replace the E8500, why can't I make the 771 converted to 775 Xeon work the same?
The only thing I wish we could do with these old 760's is to be able to overclock our processors on these motherboards. An unlocked BIOS with access to the clock rate and voltages would be really nice!
