Soltek 85DR-C (i845D) Mainboard

This board has two versions: the first has BIOS based on the Modular 6.00PG from Award, the other - on the AMI 2.01. We have the first version which contains a wide range of settings and Red Storm Overclocking and SmartDoc Anti-Burn Shield technologies.


  • Package: an ordinary design for this company;
  • Documentation: a user manual and a software guide - in English;
  • Cables: 1 ATA66/100 and 1 FDD;
  • Additional thermistor;
  • 2 CDs with software including:
    • drivers;
    • user manual in PDF for various boards;
    • several system monitoring program;
    • program for changing a FSB frequency from Windows;
    • Adobe Acrobat Reader 5.0;
    • Trend Micro PC-Cillin 2000;
    • Farstone Virtual Drive 6.01;
    • PowerQuest PartitionMagic 6.0;
    • PowerQuest Drive Image 4.0.

The layout has some disadvantages: IDE connectors are placed behind PCI slots (which makes difficult to handle them and worsens ventilation), and audio-ins are in front of these slots. However, the components are so crowded because the board is just 21 cm wide. There are two connectors for +12V for old power supply units which do not comply with the ATX 2.03 specification. A special plate is mounted onto the back side of the board to prevent troubles caused by massive coolers.

The feed circuits incorporate 9 capacitors of 2200 uF and 4 of 1500 uF.

There are the following controllers: AC'97 codec ALC201A from Avance Logic (audio solution) - the chip supports SPDIF, but the respective connector is lacking; I/O controller W83637HF-AW from Winbond (which supports interfaces of Memory Stick and Secure Digital Card Readers for which there are connectors onboard).

There are no any non-unsoldered connectors.

Brief characteristics of the board: memory slots - 2 DDR SDRAM; expansion slots - AGP/ 6 PCI/ CNR; I/O ports - 2 COM/ LPT/ 2 PS/2/ 4 USB (though the chipset supports 6); dimensions - 305x210 mm.

Adjustment can be carried out with:

jumpers and switches Jumper to clear up CMOS
Jumper to choose a flash card adapter type SD/MS
Set of jumpers to set up a FSB frequency 100, 103, 105, 111, 130 and 133 MHz
Set of jumpers to set up memory voltage 2.5, 2.6, 2.7 and 2.8 V
Set of jumpers to set up AGP bus voltage 1.5, 1.6, 1.7 and 1.8 V
BIOS based on the v6.00PG from Award Setup of memory timings + CAS Latency, Active to Precharge Delay, RAS to CAS Delay, RAS Precharge
Setup of memory frequency + DDR200, DDR266
Setup of AGP bus -
Setup of PCI bus +
Changeable scaler of AGP and PCI buses - For AGP - 2:2, 2:3, 2:4, 2:5, 2:6, 2:7 and 2:8
Manual assignment of interrupts +
Changeable FSB frequency + In 1 MHz steps, 100 - 255 MHz
Changeable CPU multiplier + x8 - x50
Changeable core voltage + 1.1 - 1.85 V, 0.025 V step
Changeable memory voltage -
Changeable chipset voltage -
Changeable AGP bus voltage -

A wide range of settings and an excellent speed of this board can help it take first places in the sales ratings.
