Steve adds a second 1-GB 240-pin DIMM to his PC, which should bring the total RAM in the system up to 2GB. The PC has an Intel Core 2 Duo 3-GHz processor and three 240-pin DIMM slots on the motherboard. When he turns on the PC, however, 1 GB of RAM shows up during the RAM count. Which of the following is most likely to be the problem?
A. Steve Failed to seat the RAM properly
B. Steve put DDR SDRAM in a DDR 2 slot
C. The CPU cannot handle 2 GB of RAM
D. The motherboard can use only one RAM slot at a time
A. 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?
A. What speed of RAM he needs
B. What type of RAM he needs
C. How many pins the RAM has
D. If the system can handle that much RAM
D. If the system can handle that much RAM
What is the primary reason that DDR2 RAM is faster than DDR RAM?
A. The core speed of the DDR2 RAM chips is faster
B. The input/output speed of the DDR2 RAM is faster
C. DDR RAM is single channel and DDR2 RAM is dual-channel
D. DDR RAM uses 184-pin DIMMs and DDR2 uses 240-pin DIMMs
B. The input/output speed of the DDR2 RAM is faster
What is the term for the delay in the RAM’s response to a request from the MCC?
A. Variance
B. MCC gap
C. Latency
D. Fetch interval
C. Latency
How does an NMI manifest on a Mac OS X system?
A. Blue Screen of Death
B. Pinwheel of death
C. Interrupt of death
D. NMIs only happen on Windows systems

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. What could be the problem? (select the best answer.)
A. His motherboard only supports single-channel memory
B. His motherboard only supports dual-channel memory with DDR RAM, not DDR2
C. He needs to install a third RAM stick to enable dual-channel memory
D. He needs to move one of the installed sticks to a different slot to activate dual-channel memory.
D. He needs to move one of the installed sticks to a different slot to activate dual-channel memory.

A. System
What is the best way to determine the total capacity and specific type of RAM your system can handle?
A. Check the motherboard book
B. Open the case and inspect the RAM
C. Check the Device Manager
D. Check the System utility in the Control Panel
A. 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. What is most likely the problem?
A. Gregor installed DDR RAM into a DDR2 system.
B. Gregor installed DDR2 RAM into a DDR3 system.
C. Gregor installed RAM that didn’t match the speed or quality of the RAM in the system.
D. Gregor installed RAM that exceeded the speed of the RAM in the system.
C. Gregor installed RAM that didn’t match the speed or quality of the RAM in the system.
Cindy installs a second stick of DDR3 RAM into her Core i5 system, bringing the total system memory up to 4 GB. Within a short period of time, though, she begins experiencing Blue Screens of Death. What could the problem be?
A. She installed faulty RAM
B. The motherboard could only handle 2 GB of RAM
C. The motherboard needed dual-channel RAM
D. There is no problem. Windows always does this initially, but gets better after crashing a few times.
A. She installed faulty RAM
