I can't set Athlon 2800+ to 166MHz

R

Robbo

Hello!

I have a computer with parts described below:

*** Processor
AMD Athlon XP (Barton) 2800+
Fan: Gigabyte 3D Cooler

*** Mainboard
Gigabyte 7N400 Pro2 (rev. 2.0) FK

*** Memory
2 x 512 MB, TwinMOS
Model: M2G9J16-MK
PC3200(CL2.5) DDR-DIMM
Dual Channel

*** Graphics Card
ATI Radeon 9500 Saphire

*** Case
Chieftec 2BD-601A-CMO1-X-1
Power supplier: Chieftec, ATX-1136H, max.load: 360W

*** HDD
Some model of Samsung (SATA).

*** Others
DVD recorder TDK, FDD 1,44''.


My problem occurs, when I set in setup, FSB Frequency
to 166MHz (the processor is shown as AMD Athlon(tm)
XP 2800+, during starting of my computer):
- Windows XP during starting hangs up or the computer
restarts -- after a few tries of starting, Windows is
deffinitelty out of order. I could not start VGA mode or
service mode.
- Fedora Core during starting shows memory page faults
and nothing else. Once, it was possible to run Fedora
but many errors were showing on the screen and applications
were closing with errors.
- SETUP works perfect.

If I set FSB to 133MHz (processor is shown as 2200+),
everything works OK.

Jumpers CLK_SW and CLK_RATIO are set to AUTO.

Configuration of SETUP:

*** Advanced Chipset Features

System performance [Normal]
FSB Frequency [133MHz] <- problem is when I set to 166MHz
CPU Interface Optimal
Memory Frequency By SPD
Resulting Frequency 400MHz
Memory Timings Normal
T(RAS) 8
T(RCD) 3
T(RP) 3
CAS Latency 2,5
AGP Frequency [Normal]
AGP 8X Support [Enabled]
AGP Fast Write Capacity [Enabled]
CPU Thermal_Throttlig [50.0%]
....

*** Frequency/Voltage Control
VCORE OverVoltage Control [Normal]
DIMM OverVoltage Control [Normal]
AGM Over Voltage Control [Normal]


I tried to set higher VCORE and DIMM.
I checked memory with "memTest".
I experimented with 166MHz and lower
ratios set with jumpers.
I reseted CMOS.
I used "System Performance" in manual mode
and set lower frequency to memory.
I set "System Perfornamce" to turbo.
I set "Memory Timings" to turbo.
Unfortunately, described experiments did not help.

Please, help me. Thanks in advance.

In Bios settings, use manual settings where possible - instead of AUTO.
AGP settings - many systems aren't stable with Fast-Writes enabled so turn
that OFF.
8x AGP can also be dodgy and yields no noticeable difference over 4x so try
4x for now.
Try RAM at 333mhz rather than 400 - synchronous speeds are often better for
performance
and if it works you can always try tighter memory timings at the lower FSB.
Lastly your PSU may well be a bit weak to run that system stable - its not
the wattage that's important but the quality of the PSU and the amperage it
delivers on the 12volt rail.

I "think" your memory can't run as fast as your CPU. If I reall, I had to
get some some real good memeory (Crucial) to run my 3000+ barton. Now both
run at 400 FSB fine, but any lessor chips wouldn't.

It's FSB 266Mhz so you set it to 133Mhz not 166Mhz, should show in
windows as 2.2Ghz+ I've got 2400xp shows as 2.02Ghz.
