Hi. I have a Dell Precision T5400 that I got with 4 gigs of ddr2, ecc ram. I am looking at a option of getting some more ram from my friend who is working in a company with many old pcs. He is asking if I need ECC or non-ECC ram. Also, this pc will be used for gaming mostly and watching twitch.tv streams.

EDIT: Thanks for help. I just noticed the FBDIMMs are the ones with heat spreader, and those get fairly hot in my system. Does T5400 support regular ECC memory? If no, any advice on cooling the RAM? I noticed the ones closer to chipset heatsink are warmer than the others. I unmounted the memory fan, removed the flexbay (mounting the HDDs with bungee cords in the .25'' bay - much, much quieter now), and I'm currently having the memory fan laid right on top of the modules. Seems to be running colder, but I'd also like to maybe put on some aftermarket heat spreaders if that is possible, or maybe get a cooler for existing FBDIMMs that would mount on top of them.

That would be all I'm asking, the system is running pretty well as is now, no errors, just updated BIOS and put in a GTX 750 Ti, games running great. Speaking of which, SLI maybe?
