Anybody have one of these boards on the way to me.
Err, I don't think I do, have I forgotten something?
I was wondering what sorts of memory are suitable?
I have nomanual for it. My present understanding is that the board will cope
with a bus speed up to 133Mhz.
Would you match the memory speed to that of theCPU bus speed?
Well I used to have one back in the day, you should be able
to find manual and other docs on AOpen's website, but if
they're gotten rid of those then let me know and I'll dig up
the manuals and such.
Earlier versions of the board didn't have the correct PCI
divider for 133MHz FSB, but the later did. Even so, because
it's a BX chipset that 133MHz FSB would put the AGP @ 89Mhz.
So, it's not officially supported though you may get it to
work with a video card tolerant of 89MHz, which was more
likley if/when there is an option for disabling SBA
(side-band addressing). I don't recall if that board allows
it or if you'd need a video drive that does this.
Anyway, keeping the issues with 133FSB in mind it should run
any coppermine Celeron or P3 FCPGA, which went up to 1.1
GHz.
As for memory, it supports max 256MB per slot, 768MB total,
low-density 16x16 modules that early in PC133's debut, were
sold as PC133, but these days most modules you'd find spec'd
as PC133 are the higher density you can't use. It seems
resellers are often differentiating lower-density by merely
calling it "PC100", though "most" modern PC100 memory can do
133MHz, providing you don't try too low a timings... and I
vaguely recall some issue of needing to turn of "precharge
delay" or something like that but the finer details escape
it, it's been a while.
You would be running memory at same speed as FSB, though @
133 you might not find the board stable with all slot
populated, though it would also depend on the specific
memory, there's no way for me to go back in time and test
that board with any of today's, specific modules. Generally
speaking you'd probably have the best luck with a pair of
PC100, 256MB modules in the first and last slots, and using
a 100MHz FSB CPU. The board would also work with a slotket
adapter and socket 370 Coppermine, and "maybe" a Tualatin
Celeron but it really wasn't meant to handle so many amps
power delivery to the CPU, if you went that route you might
want to keep an eye on the mosfets and capacitors for
overheating potential.
Anyway I just checked and still have all the docs, bios, etc
for that board zipped up, and since it's probably easier to
get them all at once if they're even available anymore, here
they are:
