if i want to expand to 8mg ram, do i have to replace all existing ram?

Yes you will need to replace the memory installed to upgrade to higher memory. Be sure it is compatible!! Once done go to setup let it recognize the new memory and boot to windows.

You can upgrade to 8GB of RAM for this computer. For any/all other specifications you can visit Dell's website and get learn all about this computer. Here is a direct link to this system. http://www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf

You probably will have to replace what is already installed, since there is usually only 2 slots to plug in the RAM modules.

Specs don't say RAM is expandable. You have to go much further up the product line for upgradeable RAM.

You can use 8Gb modules, there's only 2 DIMMS. I'm using Corsair DDR 3 16GB kit of 2 8Gb1600Mhz

Yes, you can. I did that with my W-530. The way that I did it was to buy all new memory so it was matched, so I put in 4 8GB sticks and took out the memory that came with the machine. This way I had all matched memory.

Ram memory is soldered so it is unexpandable. You'd have to purchae the variant with 8GB by default. SSD is mSata so you can expand manually.

You can replace one of the two sticks of 2 GB of RAM, which means you will have 6 GB. Before you proceed with this configuration, I recommend you confirm both RAM sticks (new and old) are the same speed (1600MHz).

I haven't done it yet, but it shouldnt't affect your ability to upgrade your ram. If anything it will only help your performance.

I'm not sure, but I can tell you when upgrading RAM you need to make sure of 3 things: 1. Type (this determines the pin configuration of the gold connectors on the bottom). 2. Speed (faster speeds in a system using a slower chipset will *usually* scale down, but slower speeds in a system using a faster chipset will slow the entire system down). 3. Amount (1 gigabyte up to 16 or more, as each hardware and each operating system has it's own minimum and maximum amount of RAM it can use). You can usually find the answers to all of these by going to your manufacturer's website and looking up your particular machine.

Yes you can but the only downside is you'll be using only the 3gb of ram instead of the 6gb

Yes. In fact, you can go all the way up to 32 GB if you want (you will need a total of four 8GB chips).

Ram is, assuming that the system can handle 16GB SODIMM memory, it comes with 2x8GB and these would have to be replaced with 16GB sticks. Similarly, storage can be expanded but only if you're OK with imaging and swapping a boot drive since there's only room for on internal drive. Access to both memory and storage requires you to remove the back cover of the screen which is straightforward. The system also comes with several USB3 ports, so adding external storage isn't a problem

No, the RAM is soldered to the logic board in all of those models. You would have to upgrade the whole logic board.

Yup, you just have to buy the two 8GB ram sticks and replace the two 4GB ram sticks currently in the computer. However, there are only 2 RAM slots, so you wont be able to have four 4GB sticks, but instead 2 8GB RAM sticks

There are 2 open memory slots under the access cover. I was able to upgrade it to 32GB of RAM with no trouble at all.

I would have to look but i think you can upgrade to 32 gigs of ram, i believe there is three more open bays.

Yes, it's a really easy upgrade to 8GB. There's one slot, take 2GB out and put the 8GB stick in.
