12/7 Followup to the hardware problem yesterday: I down-clocked the
FSB to 100MHz and the problem went away. The memory went from 266->200
the CPU went from 1466->1100, but the AGP and PCI stayed at 33MHz.
Since memtest showed the memory itself is probably OK, and GIMPS showed
no CPU problem, that says to me the AMD 761 Northbridge is the problem.
Thanks to everyone who helped with this tricky problem.
\_ No such thing as a 33MHz AGP (not commercially at least).
\_ Did you have it overclocked in the first place???
\_ No, it was all to spec.
\_ heh, same with my younger brother's computer. He was mighty
pissed he spent ~ 2x on Corsair super-elite CL2
memory and had to go back to CL3 AND reduce his bus frequency.
This was on a Pentium 4 2.26 GHz, MSI motherboard, with
Intel chipset as well.
FYI, my Athlon 64 3200+ Newcastle with an Asus mobo and two
sticks of CL3 Kingston 512MB work fine, but it has the same
problem with random games in the dynamic frequency-clocking
mode (I had to fix it to stay at 2.2 GHz).
\_ Where did he buy it from? Or did he assemble it
himself?
\_ Newegg, both DIMMs are the same - it's probably a flaky
mobo that worked fine with 512 MB but had problems going
to 1 GB at the spec'd speed
\_ maybe your northbridge could benefit from better cooling. |
