Unfortuantely, neither your chipset (Q35) or your motherboard support 4GB sticks of RAM. http://www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf and https://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core_2_chipsets The most your system can handle is 4x2GB at DDR2-800. None of those kits will work 🙁

The manual was written before 4 gig chips were available. Many have installed 4x4 gig on the 755. Just read this post:

The memory you linked didn't say it was either "low density" or Intel compatible. Consider this:

You are already running in dual channel mode with four RAM sticks. Going from 8 to 16 GB, even if your system will run it, will not make the computer faster. Your main issue is the CPU.
