L2 Cache

Speedup

I wanted to get more speed out of L2 cache. Memory settings are automaticaly configured by BIOS.
Baseline settings


Changed BIOS to manual and tested with speedsys.

Cache/Memory Benchmark                

                     Read          Write         Move         Average  
 Cache Level 1    113.16 MB/s    38.29 MB/s   143.89 MB/s    98.45 MB/s 
 Cache Level 2     61.30 MB/s    38.05 MB/s    32.25 MB/s    43.87 MB/s 
 Memory            26.51 MB/s    38.65 MB/s    11.35 MB/s    25.50 MB/s 

New settings in BIOS

512 KB L2 cache

Bought some new UM61512AK-15 L2 chips so i can upgrade to 512KB of L2 cache. I all ready had 4.
Installed and changed some jumpers on motherboard.
512 KB of L2 cache

To test out this 486 PC i used speedsys tool.

Here are the results.
First HDD and PCI/ISA info.
 CPU  external L2 Cache is in Write-back mode.
CPU info and second HDDinfo.
