Socket 775 Xeon in Optiplex 755/760?

[HardwareExtreme]

Does anyone know if this is possible? I would like to try putting something like a Xeon X3380 in one, since they are over 3Ghz and are cheaper than equivalent Core 2 Quads. It would be a Minitower.

Based on the specs sheet for the Dell Optiplex 755 and the Brochure for the Dell Optiplex 760, neither lists any Xeon processor as supported, so I would say no.

it should be possible you need a sticker to switch one pin though

i think dell will not allow that. maybe have bios post but it will have bad words like "CANNOT DETECT YOUR PROCESSOR CONTACT DELL FOR FUTHER ASSISTANCE"

dells can be picky about this but i have seen afew people have sucsess doing this

 

[Amdlova]

try it remember to get the stick xeon are 771 and the core 2 quad is 775p.

 

[HardwareExtreme]

I know that X3xxx series xeons can be used, the 771 ones can be pinmodded. However, I would like to use a Socket 775 Xeon, and since a X3370 is about $40 compared to a Quad Q9550 being over $100, it seems to be a better choice. Has anyone tried any of the X33xx series socket 775 Xeon in either of these models or a Opti 780? I do not want to damage the CPU socket with a 771 mod.

 

[junkeymonkey]

there was no 775 xeon you use a 771 with a adaptor / sticker on a 775 board

then I guess its down to bios compatibility ??

good luck

There is most certainly a thing as socket 775 Xeons. Like this one: http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20X3370%20-%20EU80569KJ080N%20-%20AT80569KJ080N%20%28BX80569X3370%29.html
The same one on Intel ARK to be sure: http://ark.intel.com/products/35433/Intel-Xeon-Processor-X3370-12M-Cache-3_00-GHz-1333-MHz-FSB

However, has anyone gotten this one or any similar one to work in a 755/760?

i have see ones with the sticker work so i would imagine that would work fine. however, i have never seen a 775 xeon that hasnt been moded

maybe now show a compatible 775 motherboard [non server] and available ...

also look at skylake and all this have in common as well

775- no xeon support [non server] - 1151 - no xeon support [on 100 series server chipset only]

775 - ddr2/ ddr3 support - 1151 ddr3 and ddr4 support

to me its like a 1/2 butt platform stuck between transitions of platform changes - look how many cant upgrade there memory on 775 with todays modules cause there not compatible any more - in the end you may find you spend time and money on beating a dead horse

good luck

 

[HardwareExtreme]

It's not really beating a dead horse, yes, it is old, but a 3Ghz or better quad core can beat a 4th Gen I3 and earlier Core i5s with a little overclocking. I do not have the money for haswell or Skylake currently, and 775 is what I have. (I am running a Pentium 4 3.2Ghz and a Pentium D 2.66 GHz)
I didn't ask whether you think I should do it or not, I just merely asked if someone knew if someone else had gotten that processor to work.

 

[junkeymonkey]

like wolfshadow said consumer boards [non server] for 775 as far as I know don't have xeon support listed in there cpu lists or bios support , but as you see around the web back then it seemed to of worked fine even with using that 771 to 775 adaptor ?

thing is is that dell and its dell bios as open to that as aftermarket boards like we got from asus -giga msi or asrock???

look over the dell forums on your model and see if anyone did it

I guess you would find some good info there

get a cheap chip from like e-bay and stick it in and see where you end up ?? it will work out or it will not

bottom line is none of this is officially supported by Intel or motherboard manufactures you do it at own risk and winging it all the way

Does anybody know if you can use ECC ram in a 760? And when I say this, I mean with the Core 2 Duo e8500 that I have, or maybe a Xeon if I can afford one.

no

 

[HardwareExtreme]

Can 2 4gb DDR2 dimms be used, then? ECC ram is cheaper than plain DDR2 for some reason.

it only officially supports 2 gig dims so i would say dont try it but if you do their is a chance it will work

 

[junkeymonkey]

onr thing to look at is how todays memory may not now be compatible with older 775 type boards

[for example]

Hi, I'm Jewel with Kingston Technical Support and would like to offer our assistance. It is possible that the HyperX 4GB memory modules are Single Rank as the latest builds of that part number are Single Rank. Up until recently 4GB modules were standard Dual Rank. Basically, the issue that can occur is that the memory module uses high capacity individual memory chips (DRAM) that the motherboard is not equipped to recognize. Usually, if a motherboard is able to recognized standard 8GB modules it should not have an issue recognizing Single Rank 4GB modules. A "1R" may be printed on the label which would indicate it as single rank. Otherwise, we can confirm this based on a reference number printed on the memory label that we can look up in our system. Other common issue with the DDR2/DDR3 combo motherboards that can be overlooked is that it only supports DDR2 OR DDR3 memory. This means you cannot have both DDR2 AND DDR3 memory installed at the same time, it is an either/or option. We do not currently support your PFG41C-M LX motherboard as we no longer manufacture memory that would be compatible with that motherboard. For any further assistance, please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you. Please be sure to have the part in question on hand when you call.


theres a few brand that still offer compatible memory sticks but you have to look hard and may not be what you really want [it maybe down to take what you can get ]

I have a 960 as well, which can use 16gb of ram total. I may use it instead of my 760.

 

[El_Ziggo]

I know this is an older thread, but I didn't see where anyone definitively answered the question about the Optliplex 755/760 using Xeon processors.

From what I have read and what I have done, you absolutely can use any 3000 series 775 Xeon processor on these systems; no bios update needed. I have put a X3230 in the Optiplex 755, 760 and 960 as a direct replacement of either C2D or dual core pentium with no issues what so ever. So, I know for a fact that the X3230 works as a direct change out. Dell isn't going to tell you this anywhere in their spec sheets. I have another 755 waiting until I can get my hands on a X3380 to test on it as well, but I have absolutely no reason to think it won't work...

Be careful with the 760. They came with 2 different motherboards. One of them is dual core only and has a 65W CPU limit. #0M858M

 

[HardwareExtreme]

Mine had the motherboard that supports quad cores ( I had a Q6600 running in it). Would a Xeon likely work in a 960 if it works in a 760?
