Does Dell's Optiplex 760 MT support Quad-core processors?

[Skillfull]

Long story short I have the Optiplex 760 Mini Tower, and I couldn't find an answer if I could get a quad-core processor in. My motherboard is 0M858N, some claim that it won't support q6600, some claim it will... I'm not sure anymore.

Any help appreciated

According to this thread it should support 45 nm 95W Quad processors, but the older 65 nm 105W Q6600 is not on the list: http://en.community.dell.com/support-forums/desktop/f/3514/t/19475957

That's why I said I'm not sure - few sites claim it does support Q6600, few say it doesn't.
Also, I could probably get a processor from the list, but I don't want to pay $50 and for it to end up not working

The Optiplex 755 supports the Q6600, but it was sold with 65 nm processors and it has a slightly stronger VRM.

This thread clearly indicates that the Q6600 doesn't work: http://www.tomshardware.com/answers/id-1971774/graphics-card-optiplex-760.html To use a Q6600 you need an Optiplez 755 motherboard.

http://en.community.dell.com/support-forums/desktop/f/3514/t/19377487 indicates your motherboard is compatible with the following Quad processors: Q9550 Q9650 Q9400 Q8300 Q8200

Where does it say that DuaneJ tried Q6600? He said that he tried a "quad processor"? Also "For Reference: LGA 775 Quad Core will NOT work in North Bridge Intel Q45/Q43" - what is that? Q45/43 doesn't work with quad cores?

You are correct; I read it too quickly. He says that a Q9650 doesn't work. Basically you have to presume that if it wasn't sold with a given CPU, then it won't work. What will you do? Buy a 755 motherboard or try the Q6600 with your 760 motherboard?

Can you quote where he says that he tried the Q9650?

I'll try something with my 0M858N motherboard that isn't Q6600 (and Q9650 if you quote it).

Above the post that you quoted, he wrote "Thank you very much for the heads up. I have been doing some research and I am assuming since your saying that I should go with a intel dual quad core that this optiplex has the 775 chipset and if so this is the best one I've found: intel q9650"

Then in the post that you quoted he wrote "I installed the quad processor.. Didn't get your message until after you have posted. The quad processor didn't work...." I have to presume the Quad is the one that he found, but we don't know if it was tested good in another system.

The statement that the Q35/Q45 chipset doesn't support Quad processors is incorrect:: http://www.cpu-upgrade.com/mb-Intel_(chipsets)/Q45_Express.html Support has to be provided in the BIOS and the VRM has to be good enough.

http://www.dell.com/downloads/emea/products/optix/optiplex_760_spec_sheet_en.pdf?dgc=BA&cid=299605&lid=5718620&acd=123092226602942957c94940922&ven3=104103104257089029 shows that Q9000 processors are supported, but they don't specify which motherboard is required.

More that don't specify which motherboard is installed:
Q8300: http://www.pcworld.idg.com.au/review/dell/optiplex_760/309691/
Q9550: http://www.amazon.com/gp/offer-listing/B00E79XLV0/ref=dp_olp_0?ie=UTF8&condition=all

Unfortunately nowhere could I find evidence that your motherboard officially supports a Quad.

Hi everybody, today I installed a Core2quad Q9400 on my old 760 MT (0M858N MOTHERBOARD. A16 BIOS VERSION) and it worked as expected. I hope this information help more people. thanks.
