Can an Optiplex 320 pair with a QX6700?

[Dreznon]

Before we get on a war of what year it is, I would just like you guys to know I am aware.

I have done extensive research on this and it seemed as if I found a few threads with people running a core2 quad 6700 in the Optiplex 320. It woud be sufficient to run basic software for another two years and at the going rate of $20, I couldn't pass up the option to see.

I purchased a core2 quad 6700, but the eBay seller sent me a core2 extreme 6700 and from what I understand is that the extreme quads are locked from being used on the OEM board's firmware. I have the bios 1.1.12, just in case you are wondering.

The orange light comes on when I put the core2 extreme qx6700. I put in my core2 extreme x6800 and that is fine. I put the core2 extreme qx6700 back in and it has the orange light again. On Dell's instructions for the lights, it says a steady orange light with no beeping is a registering issue and the computer needs a minute to update to run. I didn't figure it would take long, so I shut it off after 3 to 5 minutes. Does anyone know how long that takes? Has anyone experinced that and had the computer fix itself?

I think that is about everything. I planned on getting an rx 550 for it and just bottlenecking the CPU until I get a optiplex 790 for $100 in a few months. I am poor, thanks again. I look forward to hearing from you guys.

dell machine can be picky with CPUs, I would ask you what make/model of the motherboard you have in your OptiPlex 320 (peek inside you probably be a Foxconn model xxxxx). let me know it will help in figuring out the issue
also the dell sticker should have the product model i.e. UP453, what is yours?

I"ll have to do it later tonight. I'm at college.

There is a number by the pci slots. It is CU395. The sticker on the mobo says CN-OTY915-70821-77K--1234. Underneath that barcode is another with a small alpha/number REV A00.

I hope this helps you. I will also search.

I searched the orange light with no beeps and someone said splice the green wire and attach another to it. Then do something with grounding out the case. Should I try that?

 

[Dreznon]

I have a DT btw. 280w pay.

 

[Dreznon]

I am wondering if the cpu came dead on arrival.

okay the Specs on the OptiPlex 320 MT or DT models can be read here : https://www.dell.com/downloads/global/products/optix/en/opti_320techspecs.pdf
The CU395 (also known as TY915) motherboard is indeed very common on the OptiPlex 320.
The power supplies is a 280w @ 76% efficiency (so read 221 watts under load)

to answer your CPU question, I see nothing regarding extreme series CPU being compatible to this motherboard, and I think this is your primary obstacle, why is that well the wiring (pinout) on the Extreme Cpu is slightly different than a standard Qxxxx series CPU's
so quite possible it will just not be able to run on this motherboard.

Dell clearly marks this OptiPlex 320 series MT or Dt to only support;
Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x2MB L2 cache, and EIST (900 series)
Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x1MB L2 cache (800 series)
Intel® Pentium® 4 800MHz FSB Socket T with HT, XD, EM64T, and 2MB L2 cache (600 series)
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)

its not because a cpu is 775 that it will run on your motherboard, as listed earlier the best fit according to the dell official system configuration would be a
Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x2MB L2 cache,
which is in lament terms a Intel® Pentium® D Processor 950, 4M Cache, 3.40 GHz, 800 MHz FSB
now that said, with the minimal information I could find this is best I could do.

by all the looks of it, and without other confirmation from anyone else that has "ran a Q series cpu on this motherboard" I would suspect you cannot.

But you mentioned some people running a q6700 on it, but a QX6700 is not the same pinout as the Q6700 so not surprising it doesn't run at all.

 

[Dreznon]

I know about technical guides. I understand dell doesn't officially support the cpu's I have or want.

I have tested the core2 duo e6700. Good

I have tested the core2 extreme x6800. Good.

That means Dell's list on their tech guide is false.

 

[The Paladin]

probably more likely they listed their specs a few years before the cpu's came out
so you tested both cpu and they work so you worked out the problem then ? and the x6700 doesn't work, probably right, (unless you test on another system to confirm), that cpu is dead yes.

 

[Dreznon]

There is one thing you mentioned that makes sense and that is the bottom of the chip does have a different configuration on the bottom of the chip. I dont think even a regular quad will work either.

There is a bunch of posts about this computer taking Conroe. I seen that quad cores are kentsfield.

Idk

 

[Dreznon]

It's the Pinout that makes the kentsfield not work.
