Will this work will my dell optiplex 755?

Yes it will. I'm using it in a Dell Optiplex 780 which is nearly identical and it works beautifully. Windows 7 WEI score of 5.6 for Aero Graphics and 6.9 for Gaming Graphics.

Hi, in theory, yes. I searched the internet for details about the model you have, to find out there are several types of that model(standard and slim models: http://www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf). If your model is a slim one, there may be some issues mounting a video card with a standard bracket(that's about 10-12 cm long) but would accept smaller brackets(4-5 cm). Some video cards come with a small bracket too, so before purchasing, I would make sure the card has one too(or look for a card that is "small form factor"). In addition, based on the manual from the above link, it looks like all models are able to handle PCI express cards, so from this point of view, you'd be good to go.

That should work fine, as long as you don't have too many other things drawing power from the power supply. I believe the recommendation is for a 750, but that assumes you might have multiple drives, etc.

can't be sure w/o your xpress code or svc tag - just look at the different form factors for optiplex 755 - http://www.dell.com/us/dfb/p/optiplex-755/pd that said - if your optiplex is no more than 2-3 years old - 99% yes, b/c it's PCI express ready and low profile (so should fit in small form factor - the worst case in sense of space for ext. card). given that - if I were you, unless you want to share your xpress code so I can actually check what hardware specs you have, then I'd say go for it - worst case return...

My Dell OptiPlex GX280 does not accept it either. I am not sure if the problem is with the RAM though.

Yeah! It will work, but I recomend to you the AMD Sapphire Radeon 7850, it's faster and have a lower power consupcion

If it were me, I'd give it a try. OFFICIALLY, it was never available for the 755 so I honestly don't know if the BIOS will support it but the 755 definitely IS a Socket LGA775. This discussion at Dell product support says it will work: http://en.community.dell.com/support-forums/desktop/f/3514/t/19423852.aspx . The tech specs don't mention it at all. But again, the reason is probably because the Q9650 wasn't on the market at that time. Official Tech specs can be found here: www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf .

Ask your manufacterer, I asked the seller by email. I put mine in my Dell Optiplex GX280 2002 and they work just fine. I don't even know what your PC is.

Most likely it won't work. OptiPlex 380 requires "DDR3 PC3-12800 * CL=11 * Unbuffered * NON-ECC * DDR3-1600 * 1.5V" - -- Crucial 4GB Single DDR3 1600 MT/s PC3-12800 CL11 Unbuffered UDIMM 240-Pin Desktop Memory Module CT51264BA160B

Hi there!Based on the general memory specifications of the Optiplex 755 MT, this memory should work in your system. The compatible and guaranteed to work memory module is part number KTD-DM8400C6/2G, found here: Kingston Technology 2 GB DDR2 Cl6 DIMM Memory 2 800 MHz (PC2 6400) 240-Pin SDRAM Single (Not a kit) KTD-DM8400C6/2GThank you for choosing Kingston as your upgrade partner!-Jewel, Kingston US Technical Support

Yes it will. I just installed it in my small form factor dell optiplex 620.

I can't say for your specific motherboard, but this card is working for me in a Dell Optiplex 755 that shipped on 06/02/2008 (so my MB, model number 0GM819, is 4 years 4 months old, and I believe it's PCI-E 1.0). I think the chances are good it will work for you. Red/.

I check a few sites and it seems compatible, However I would call Dell to make sure.

Yes it'll work, but first you must check if your power supply have the necessary watts for handle the video card. Thanks

It will work just fine in an OptiPlex 755; the DDR3 refers to the memory on the video card -- it has nothing to do with the motherboard (CPU) memory. The HD6450 is not a bad card for the price; I use it on my TV PC.

Looks like it would according to dell's website. http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdfKeep in mind that the OptiPlex can have a max of 8GB of ram. Therefore, if you were wanting to max the installed ram you're better off buying 4 2GB modules rather than buying 1GB modules for all models except for the Ultra small form factor. The ultra small factor uses 2 4GB modules.

As long as the Optiplex has a low profile PCI-e slot. If this is the Optiplex Micro, then No, it will not work. The Micro is an all-in-one machine. Not much for upgrading on the Micro.
