EPoX 4PDA5+ 865PE Review

4PDA5+ is fitted with 6 high quality Sanyo Ultra low ESR
capacitors of 3300μ, 6.3v each to provide additional stability of CPU power
especially for the Prescott processors. Also the 4-phase power design ensures
optimized power density and thermal performance for
increasing high CPU temperature. The CPU voltage regulating is controlled by the
Semtech SC2643VX.

4PDA5+ is fitted with a passive golden colored aluminum heatsink
on the Northbridge. Intel 865PE chipset is a discrete chipset and consists of
two controller hubs; 82865PE (MCH) and 82801DB (ICH4). The 82865PE MCH supports
a 800 MHz system bus, 4GB of DDR400 SDRAM providing memory bandwidth up to
3.2GB/s and linked to the Southbridge on Intel® Hub Architecture with 266MB/s of
bandwidth. EPoX has decided to pair up the 865PE MCH with an older 82801DB
Southbridge instead.


4PDA5+ uses IDT CV107 clock generator which is quite an uncommon
clock generator use by motherboard manufacturers. It allows 66MHz to 533MHz CPU
frequency and incorporates four PLLs to allow independent generation of CPU,
AGP/PCI, SRC, and 48MHz clocks. Since it is quite uncommon, therefore SoftFSB
applications like Clockgen or SetFSB cannot support it yet.


EPoX uses the new Realtek audio CODEC ALC850 comply with the new
standard, AC’97 Rev 2.3, providing a Jack-Sensing function, a PCBEEP Generator,
and Interrupt Capability. Realtek ALC850 features a 16-bit eight-channel DAC,
four pairs of stereo outputs, with 5-bit volume control and multiple stereo and
mono inputs, along with flexible mixing, and gain and mute functions.


Marvell Yukon 88E8001 Gigabit Ethernet combines the Marvell
Alaska PHY transceiver and a Gigabit Ethernet Media Access Controller (MAC),
with a 32-bit PCI interface and a 64 KB packet buffer. It enables host system
offloads for TCP/IP and UDP checksum generation and includes Wake-on-LAN (WOL)
support for remote manageability. It is the First Gigabit client connectivity
solution to offer Virtual Cable Tester™ (VCT) technology for reduced network
installation and support costs.


Silicon Image SiI 3114 is a single-chip PCI to 4-port Serial ATA
(SATA) host controller. Software RAID 0 (striping), RAID 1 (mirroring) and RAID
1+0 (mirrored stripe) functions are supported through Silicon Image’s SATARaid™
RAID management software utility.


The Debug Post Codes for diagnostics and testing purposes


The back panel multi IO consists of the PS/2 Keyboard and PS/2
Mouse Connectors, 1 Parallel Port (EPP/ECP),  1 S/PDIF-out Coaxial Jack, 1
S/PDIF-out Optical, 1 Serial COM Port, 7.1 Audio connectors
(Center/Subwoofer/Front/Rear/Side Surround), 4 USB Ports, 1 RJ45 LAN connector.
