Default memory too slow...

memory too slow...

Compaq Presario S4020WM computer, purchased from WalMart last year
Windows XP Home (SP1) with all of the latest updates
2.00 gigahertz AMD Athlon XP 2400+ processor
originally 128MB PC2100 DDR SDRAM, replaced with two 512MB PC2100 DDR SDRAM
modules (purchased from 4AllMemory.com specifically for this computer model)
1024MB RAM - 32MB shared video = 992MB free RAM
Board: KM266-8235
Motherboard Chipset VIA VT8375 ProSavageDDR KM266
Bus Clock: 133 megahertz
BIOS: Phoenix Technologies, LTD AM37320 08/01/2003
S3 Graphics ProSavageDDR Display adapter
originally a slow 40G Western Digital hard drive, replaced with a 7200rpm
8MBcache 120G Maxtor (6Y120P0)

The AIDA32 benchmark indicates that my memory speed is much too slow, only
about half as fast as it should be. It's the same speed as ordinary PC133
SDRAM, although it's PC2100 DDR SDRAM.

Here below is the AIDA32 benchmark list for the Memory Read operation. The
benchmark for the Memory Write operation is similar. As you can see "This
Computer" (13th from the bottom of the list) has a benchmark of only
815MB/s. It should probably be twice as fast (about 1600MB/s), as you can
see from the benchmarks for various PC2100 DDR SDRAM machines.

Why?

Is there a fix?
