Anybody been inside their HP x310 server? I would like to upgrade the memory in my HP x310 from 2GB to 4GB. I want to order the correct memory module but the server is remote so I have NOT had a chance to open it. Does the x310 use the same memory module as the ex495? A couple years back I upgraded my ex495 with g skill 4GB, ddr2, pc2-6400, 800mhz, non-ECC, non-buffered memory, CL5-5-5-15 and all has been perfect!
