P5WD2 Premium with an Intel 630 64 bit cpu working in a 32 bit environmnet with 2meg L2 cache

If anyone is knowledgeable, does the extra meg of L2 cache get
used in a 32 bit operating system? I know that the 800 series
dual core processors which have 2 megs of L2 cache and used
independently for each core (one core doesn't use the other).

So, I was wondering if in a 32 bit system, using a 64 bit cpu
whether or not the system has the use of 2 Meg L2 cache, or does
one have to be actually operating in 64 bit to make use of all
the L2 cache....

Still patiently waiting for DDR2-800 to be released to complete
my self-imposed father's day present...

thanks...

Basically the cache helps keeps the CPU from having to go through the
northbridge to the main memory which is a lot slower then the on-die
cache, so the bigger it is the better for overall performance.

AMD64 doesn't use a northbridge, the memory controller is right on the
CPU, more cache here may be less important since latency is very low.
