As you can see from
Figure 20.10
, AGP 4X or 8X (1.5V) cards fit only in 1.5V or uni-
versal (3.3V or 1.5V) slots. Due to the design of the connector and card keys, a 1.5V card
cannot be inserted into a 3.3V slot. So, if your new AGP card won't fit in the AGP slot
in your existing motherboard, consider that a good thing because, if you were able to plug
it in, you would have fried both the card and the board! In a case such as this, return the
AGP 4X/8X card and check surplus outlets or eBay for a compatible card.
I installed an upgraded processor, but it won't work
First, make sure the motherboard supports the processor that is installed. Also make sure
you are using the latest BIOS for your motherboard; check with the motherboard manu-
facturer to see whether any updates are available fordownload, and install them if any are
available. Check the jumper settings (older boards) or BIOS Setup screens to verify that
the processor is properly identified and set properly with respect to the FSB (or CPU bus)
speed, clock multiplier, and voltage settings. On some systems, you may need to press
Ctrl+F1 or some other special key combination in the system BIOS to display the setup
screens used to configure processor and memory timings.
Make sure the processor is set to run at its rated speed and is not overclocked. If any of
theCPUsettingsintheBIOSSetupareonmanualoverride,setthemtoautomaticinstead.
Then reseat the processor in the socket. Next, make sure the heatsink is properly installed
and you are using thermal interface material (that is, thermal grease) at the mating junc-
tion between the CPU and heatsink.
