A7N8X-E setup - performance problem
 

Am having perf. problems with a new A7N8X-E setup
(bios v 1009) running a new Athlon XP 2500+ (Barton),
two Mushkin PC3200 black level-II 256MB memory sticks.

When I run Memtest 86 (v3.0), it shows:
L1 Cache - 128K 11225 MB/S
L2 Cache - *Unknown* (my emphasis)
Memory 512M 1276 MB/S (this seems slow)

I checked that L1 and L2 cache are both enabled in BIOS,
of course. All BIOS setting are 'stock' (not overclocked),
memory settings 'by SPD' running at 200Mhz 6-2-2-2T.
CPU running at 11x166Mhz.

So any ideas why L2 cache wouldn't show up in Memtest-86?
