Compatible with Optiplex 755?

The only validated CPUs I can find listed are Pentium 4. Research in the Dell community indicates a Pentium D will work in your machine, but will require Bios A11 update, the last bios available for your machine. The community suggests it can take up to a Pentium D 960, but I would be leery of that, because it is a whole different structure and TDW. You never know until you try, and my E510 made great strides when upgraded from Pentium A to Pentium D. Remember the bios upgrade must be applied before replacing the processor.

I bought a Pentium D 3.4 GHZ cpu for my computer. My computer is the Optoplex 520. It uses a 775 cpu also. It didn't work because the 3.2 and above are of a different Technology than the 775 2.8 and below. I downloaded the manuale for the Optiplex 775 computer and it says a Celleron or a VPRO cpu. I never heard of a VPRO model before. I"d take a pass on that CPU unless you get an email that says it will work.

My son's computer is a Dell Inspiron 5315, which is what I bought it for. But the Dell site does say it should work with the Optiplex 745. One thing you might want to think about, when I took this memory to Best Buy to have it installed (I have a service contract with them so that was a free service), they told me I could have also bought the 4 GB kit (2GBx2) to max out the memory. This 4 GB set was also available here on Amazon for about five bucks more if I remember correctly. Hope this helps.

I used it for a Dell Precision T7400. Don't know about Optiplex since it is a smaller computer.

Hi DP yes the OptiPlex 260 is a little bit too old, probably you need to add memory that will help I bit more but not too much and if you look the OptiPlex 745 it will help more because this unit it's Pentium D3.4ghz with 2gb ram and 500gb hard drive it will be much better thank you

I think it is. No problems using it with Dell OptiPlex 3020 towers for dual monitor configuration.

Yes. I beleive it would work. You should have a PCI express slot. I have an optiplex 780 and it would work in mine.

Cant answer that question with ease but I did find one that had the 751 listed, it does work but only at the 300 Bd rate and it is very slow, but it does work and now I can see how to use the rig even it the screen dies completely. You can Em me at w4gsm@msn.com to chat. put your call and 751 in the header so I will not dump is as junk mail. Dave.

I have the tower version of the Dell Optiplex 755. The PC did not have HDMI connection. The Video Card I upgraded it with has a HDMI connection (Radeon HD 4550).

Depends on your motherboard. If your motherboard supports LGA 775 you should be fine.

This Power supply unit will work for OptiPlex 320,360 & 700 series Wouldn't advise putting it in anything higher end like the 990, etc.

Yes, google this: Dell optiplex gx620 compatible with intel penguin d 945. You will see a page on community.dell.com that says it is. Code 2 Duo is Not, by the way. I did this kind of upgrade in a HP, also maxed out its memory, and produced a very nice machine from a toaster. Total cost: $35.

Hello,Unfortunately this is fully buffered RAM and would not properly fit in a Dell 755 computer. You would require DDR2 Non-ECC 240 Pin DIMMs.
