How to remove a DIMM and replace it with another

1. pull the tabs on either end of the DIMM away from the DIMM 2. pull the loose DIMM straight out of the slot and away from the motherboard 3. ensure that the locking tabs are completely opened and out of the way of the slot. 4. align the modules notch with the tab or tabs in the slot 5. insert the new DIMM straight down into the slot 6. apply firm and even pressure downward until the locking tabs automatically snap into place 7. nudge the tabs inward toward the module to make sure that they are on tight

you are installing a new video card into a PCIe slot. What is the combined total throughput of a PCIe 2.0 x16 slot

16 GBps the pcie 1.1 specification provided 250 mbps of throughput per lane per direction. with the 2.x version, the rate doubles to 500 MBps. as a result the v2.0 lane is capable of a compined 1GBps. a x16 slot consists of 16 lanes, for a total of bidirecitional throughput of 16 GBps

you are training new techs to install RAM and pointing out differences between packages. Which of the following are the numbers of pins that can be found on DIMM modules used in desktop motherboards
