Gigabyte 8I848E i848P Mainboard Review
|
This budget mainboard has two peculiarities that distinguish it from other
i848P based boards. If you follow our reviews you must know about the Gigabyte's
Dual Miracle suite of technologies. Originally these technologies delivered
dual functionality (DualBIOS, Dual Power System, Dual RAID etc.), and the
8I848E/-L got the seventh Dual Miracle - Dual Chipset :). The models are
based on the Intel 865PE/848P chipset and the outdated ICH4 south bridge.
This particular sample is based on the i865PE north bridge. Because
of the short supply of the i848P chips and great demand for boards based
on this less expensive MCH Gigabyte installs the dearer north bridge on
some models to satisfy the demand (without ending up losing). The i865PE
and i848P are not just compatible - they are based on the same die, with
the second memory controller channel locked in the i848P. When the supplies
grow up all the boards will probably have only the i848P installed.
But the fact that some boards are based on the more expensive chipset
doesn't mean indicate their superiority: the Gigabyte 8I848E/-L supports
only those memory slots which are controlled by one controller channel
on the north bridge. You shouldn't expect the dual-channel support even
if the board you buy is based on the i865PE, its speed won't differ from
i848P based solutions (we'll check it later). Also remember that the ICH4
south bridge used on all 8I848E/-L boards limits their functionality (it
supports 6 USB 2.0 ports instead of 8 and lacks for the Serial ATA compared
to the ICH5), and it's not going to change in future supplies.
The board is narrower than usual, which affects its layout. Thus, the
IDE ports are located behind the PCI slots while the audio-ins are in front
of them. It's not difficult to reach the only jumper when the board
is already installed. Its functions are indicated on the PCB. The 3-phase
switching voltage regulator incorporates 4 capacitors of 3300 uF and 3
of 1500uF. There are also voltage regulators of the AGP bus (2 capacitors
of 1000 uF and several less capacious ones) and of the memory (4 of 1000
uF).
Gigabyte offers a wide range of i848P based models (let's consider the
8I848E based exactly on this chipset). It includes two pairs of boards
based on the same PCBs: 8I848E and 8I848E-L (the same features, plus a
100Mbit LAN controller on Intel's chip), and 8I848P and 8I848P-L (the same
difference). These pairs differ in the PCB layout and chipset functions
(the P series integrates the ICH5, that is why it has 2 SATA ports and
2 more USB), and the north bridge is based on the i865PE/i848P again. The
board tested today doesn't integrate a LAN controller with an RJ45 connector;
as there's space for a connector for an external COM port, this PCB must
be also used for another model with integrated graphics; finally, a WOL
and CMOS clear jumper are just left space for. The board measures 305x205
mm (narrow ATX, 6 fastening screws, the front edge might hang loose). One
of the LEDs indicates that the memory slots are supplied power to, the
other LED warns that 3.3V AGP cards are not supported. System monitoring
is supported by ITE IT8712F-A chip. It controls:
-
processor, memory voltages, +3.3, +5, +12 V

Performance
Among the i848P based models tested this one shows average results. It
falls behind the leaders in real applications by less than 5% (except the
extremely heavy 7-Zip archiving).
