ASRock  775i915P-SATA2  Motherboard
CAUTION!
1. About the setting of  “Hyper Threading Technology”, please check page 30
of “User Manual” in the Support CD.
2. This motherboard supports Dual Channel Memory Technology. Before you
implement Dual Channel Memory Technology, make sure to read the
installation guide of memory modules on page 12 for proper installation.
3. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
4. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
If you install PCI Express VGA card to AGI Express slot, PCIE2 slot (PCIE
x 1) and SATAII functions will be disabled. For the information of the
compatible PCI Express VGA cards, please refer to the “Supported PCI
Express VGA Card List for AGI Express Slot” on page 8. For the proper
installation of PCI Express VGA card, please refer to the installation guide
on page 14.
5.
6. For microphone input, this motherboard supports both stereo and mono
modes. For audio output, this motherboard supports 2-channel, 4-channel,
6-channel, and 8-channel modes. Please check the table on page 3 for
proper connection.
7. Power Management for USB 2.0 works fine under Microsoft® Windows® XP
SP1 / 2000 SP4.
8. Because of Intel 915P chipset limitation, Windows 98 / ME does not
support USB 2.0 but only USB 1.1. Besides, after installing Windows 98 /
ME, two display adapter controllers will appear in “Display Adapters” of
“Device Manager”. Please remove one of the display adapter controllers,
and then you can successfully install the VGA driver.
