RAM
| Question | Answer |
|---|---|
| Steve adds a second 1GB 240pin DIMM to his PC, which should bring the total RAM in the system up to 2GB. The PC has an Intel Core 2 Duo 3GHz processor and three 240pin DIMM slots on the motherboard. When he turns on the PC, however, only 1GB of RAM shows? | Steve failed to seat the RAM properly. |
| Scott wants to add 512 MB of PC100 SDRAM to an aging but still useful desktop system. The system has a 100-MHz motherboard and currently has 256 MB of non-ECC SDRAM in the system. What else does he need to know before installing? | Scott needs to know if the system can handle that much RAM. |
| What is the primary reason that DDR2 RAM is faster than DDR RAM? | The input/output speed of DDR2 RAM is faster than that of DDR RAM (although the latency is higher). |
| What is the term for the delay in the RAM's response to a request from the MCC? | Latency is the term for the delay in the RAM's response to a request from the MCC. |
| Rico has a motherboard with four RAM slots that doesn't seem to work. He has two RDRAM RIMMs installed, for a total of 1 GB of memory, but the system won't boot. What is likely to be the problem? | RDRAM-based motherboards require empty slots to be filled with CRIMMs for termination. |
| Silas has an AMD-based motherboard with two sticks of DDR2 RAM installed in two of the three RAM slots, for a total of 2 GB of system memory. When he runs CPU-Z to test the system, he notices that the software claims he's running single-channel memory? | Motherboards can be tricky and require you to install RAM in the proper slots to enable dual-channel memory access. In this case, Silas should move one of the installed sticks to a different slot to activate dual-channel memory. (And should check manual). |
| Which of the following Control Panel applets will display the amount of RAM in your PC? | You can use the System applet to see how much RAM is currently in your PC. |
| What is the best way to determine the total capacity and specific type of RAM your system can handle? | The best way to determine the total capacity and specific type of RAM your system can handle is to check the motherboard book. |
| Gregor installed a third stick of known good RAM into his Core i7 system, bringing the total amount of RAM up to 3 GB. Within a few days, though, he started having random lockups and reboots, especially when doing memory-intensive tasks such as gaming? | Most likely, Gregor installed RAM that didn't match the speed or quality of the RAM in the system. |
| Cindy installs a second stick of DDR2 RAM into her Core 2 Duo system, bringing the total system memory up to 2 GB. Within a short period of time, though, she begins experiencing Blue Screens of Death. What could the problem be? | If you have no problems with a system and then experience problems after installing something new, chances are the something new is at fault. |
