Hi all,

Bought a new board and processor last week,
as a replacement for my old PII-450.

The new board is an ASUS A7N8X-X, (the budget
version of the A7N8X) with 1Gb of DDR400 RAM
and an Athlon XP3000+. Board is running
BIOS 1009, the latest version. (Actually,
just checked, 1010 was released on Tuesday).
Even though some people here had problems
with the A7N8X, my Pulsar I seemed to work
fine on the new system.

Then came the problem: When I run the
processor at normal speed (BIOS:CPU External
Frequency = 100Hz, giving the processor
2100 Mhz), the Pulsar doesn't manage to
slave to my Roland VS2480 via the ADAT/RBUS
bridge.
It only starts slaving properly with the
CPU External Frequency around 150 Mhz. I can
then increase the CPU multiplier to 11.5,
which gives me around 1735 Mhz on the Athlon.
Obviously, missing out on 400 Mhz speed does
not really satisfy me!

Does anybody know what's going on here?
Mind you that the Pulsar runs fine in master
mode with the CPU at 2100 Mhz, I can load
masterverbs, do a 32 channel routing setup
through ASIO, all no problem.
Fact is that I have to slave the Pulsar to
the VS2480, as it doesn't want to slave
to the Pulsar anyway (that's a Pulsar
problem) and as I use the AD-converters on
the VS2480, the Pulsar as slave would be
the right setup anyway.
I've already disabled everything on-board
in the BIOS, and it doesn't matter in which
slot I have the card, the same behaviour
persists.

Can anybody share his A7N8X settings with
me? Most of them should be applicable to my
A7N8X-X anyway.

Or if anybody knows why this is happening,
your answer will off course be mostly
appreciated :grin:

Regards,

KrasS

Me too , i have problems to run pulsar as adat-slave. are you really sure it has something to do with the frontside-bus-speed?? the pci bus is running at 33MHz anyway, isnt it?

in my case, the pulsar can be master or slave, but in any case the PLL of the adat-in can not lock. everything looks fine, no errors, but pops n clicks.

... can not lock.
sorry, wrong guess. it turned out to be a mme-driver problem under XP. my pulsar1 is syncing just fine to the adat-ins.

Not that simple on my side though...
