very weak
The first Google result on "Optiplex 745" is: www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf which says DDR2, 533Mhz and the first Google result on "Gigabyte GA-945-PL-S3" is www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2325 which says DDR2 533, so, yes the RAM will be compatible, probably, as should be the CPU and HDD, so you're in luck there, probably.

That said, if you cannot work out this by yourself I'm not sure I'd trust you with a screwdriver to open the case, so I take no responsibility for your certain death by accidentally slashing your own wrists with a surprisingly sharp stick of RAM.

In fact when this happens, I demand you post pictured by way of payment for the 2 minutes of my life spent copying and pasting simple search terms into Google for you.

You spacktard.

Edit: oh fuckity fuck, it the time I spent adding insults to my post someone else beat me to it, with a polite response grrrr.
