I have found the Athlon + AMD 751/756 Chipset to be
UNUSABLE in Linux. Apparently, I am not the
page for this CPU/Motherboard combo indicates that it works for
Mandrake and SuSE. I found that it doesn't work at
all with either Debian Potato or Woody. (I would have submitted a
comment to the page pointed to above, but they required me to
provide a valid email address and I refused to do that. I wonder
how many other sites have incomplete information due to their
anti-privacy policies. Note that the site that would not accept my
comments without a spam target, www.LinHardware.com, is
AMD Athlon 750 MHz
Two CAS-2 128 MB DIMMs
All combinations (1&2, 1&3, 2&3) tried.
Windows 98 and Windows NT were installed. Only a few blue
screens were noted. (Nothing out of the ordinary.)
Debian Potato was installed. System had severe problems
with virtual memory and page swapping.
The kernel was recompiled with MTRR support. A SuSE page
indicates that this is necessary for the Athlon/K7. Using the
new kernel with MTRR support did not help.
In an attempt to make the system usable, it was underclocked.
The front-side bus was clocked down to 90 MHz, and the CPU was thus
clocked down to 675 MHz. Underclocking didn't
help. The system continued to be instable under
Only 12 MB was recognized without a special LILO append
line to force the 256 MB to be used.
Debian System was upgraded to Woody. System continued to have
severe problems with virtual memory and page swapping. The
Debian package management system database was corrupted several
times. I finally gave up after the kernel panicked
over corruption in the ext2 root filesystem.
In my 9+ years of using Linux (since Oct '91), I have never
seen so many kernel panics.
The Athlon CPU & AMD 751/756 Chipset motherboard
combination SHOULD NOT BE USED for Linux.
