Biostar M7VIB help with Duron

[stevenkwong]

I'm new to Durons, so if anyone have any experience with the following:

I brought a Biostar M7V1B (KT266) with a AMD Duron 1gig (200Mhz) and an Evercase ($42 at neweggs).

What should I set the onboard FSB to be? 100 or 133 Mhz?
What should I set the DDR voltage? (default is 2.65v, settings available is 2.55-2.85v)

The case has the following plugs for front USB connectors:

(1) +5
(2) +5
(1) +D
(2) +D
(1) -D
(2) -D
GND
GND

The MB has 2 clusters of pins:

+5V +5V
USBP2- USBP3-
USBP2+ USBP3+
Ground Ground
KEY NC

+5V +5V
USBP4- USBP5-
USBP4+ USBP5+
Ground Ground
KEY NC

Since an USB plug has 4 pins, I figure there is +5V, D+, D-, GND. However, the 2 GND plugs aren't labelled, so I don't know which is which. Also, on each cluster of pins on the MB, there are 2 sets of each...

To answer my own questions (for future ref.)

I left the DRAM voltage at default (2.65v)

I set the FSB to 100Mhz (will try 133 tomorrow)

I connected all of the case front USB plugs to 1 "cluster", matching (1) to the lft side, and the (2) to the right side. Both USB connectors works fine.

CPU temperature is 55-57 C with the Coolermaster $9 fan from TWCO.com

I wouldn't bother setting the FSB tto 133, Steve.

I don't think that Duron 1 GHz is going to do 1.33 GHz.

Thanks JonnyGURU.

I've tried 124/31 Mhz (FSB/PCI) with no luck (PC won't POST.. had to reset CMOS) since I was already at ~55Mhz with artic silver, I didn't want to up the voltage anymore..

Right now, I'm trying 109/33 and it seems stable. SISsoft Sandra numbers looks decent.

I'll try a few other combinations and provide my results here..

You mean 55 degrees, not 55 MHz, right?

FYI: You can "clear the CMOS" by holding down the INSERT key while you power up rather than move the clear CMOS jumper. Documentation doesn't tell you that.

Yup, I found out about the INSERT key boot after I read all 73 pages of the PDF manual. Very convenient.

The highest I got was 114/38 FSB/PCI. Everything higher didn't POST.
Its very stable right now at 1.75V + 0.025V. 63C temperature at heavy load.

Last night, it went to 61C when it was 100/33 Mhz and 1.75V using the standard sticky pad that came with the heatsink. Today, using artic silver, the max temperature I got up to is 63C. It hovers around 60C right now.
I think thats ok for now.

Keep in mind that the thermal monitor on that board is calibrated WAY HIGH. Your 60C on this board is like 45C on any other board I've used.
