Big M7NCD Issue, please help!

External Since: Nov 22, 2003 Posts: 2

Hi All, this is my first post to this newsgroup. Well, heres my jam. I
have an AMD 2400+ (old core) with a Biostar M7NCD, and have problems
with the computer intermittently turning off. At 100mhz, it is fairly
stable, albeit it is underclocked. It runs at under 50C. When I try to
clock my CPU at 133mhz it become much more sensitive and reboots
whenever it has to do anything remotely graphics intensive (e.g. Quake
III). The temperature remains very low, under 60C. I first thought it
was video card, but ruled that out. I also tried messing with the
Thermal Throttling, not knowing exactly what it does, and the system
would just get worse. I found that it works best around 50%. My
question then is, how do I keep the machine from rebooting all the
time? I've seen similar threads to mine in other newsgroups, but they
have yet to receive a response. Any ideas?

Thanks!!

John

First, if you're going to cross post, please do it properly so that a single
response will go to all your postings. You do that by including multiple
newsgroups in the Newsgroups: textbox of your draft message.
Second, here is my response, posted in the overclocking group:

Overclocking? With a board with no multiplier adjustment and FSB adjustments
of 100, 133, 166 and 200 MHz only? But, I digress.
I have a Biostar M7NCD running an XP 2400+ in a PC in my office. It runs the
CPU at default speed (133 x 15) with the PC2700 memory at 166MHz with
complete reliability. It's your temperatures that I wonder about. As you
didn't post case and room temperatures, it's hard to be precise, but as the
M7NCD temperature sensors measure socket, not diode temperature, I think
your readings are a bit high. My example idles in the 36 - 38C range and
doesn't exceed 43C under full load.
So, we need details, if you want good suggestions. What are the case and
room temperatures? What brand, model, speed RAM are you using, and have you
tweaked the timings in the BIOS? What do you mean by "old core"? Have you
tried resetting the BIOS to failsafe or optimized defaults? What type of
video card, and have you tried updated drivers?
I hope you get the idea. You want us to diagnose your PC sight unseen, so
you need to "paint" the best, most complete, picture you can.
