Note that such stuff can easly be found in the manual of your motherboard. If you don't have the manual, look it up on the net:
For the Asus A7NX motherboard (or any Asus motherboard for that matter), look at the
download section on Asus' official homepage:
Product: Motherboard
Series: Socket A
Model: A7N8X
There you'll find:
- Aflash (v2.21), an utility to update the flash BIOS
- A7V-M flash BIOS
- VIA Audio Driver
- Realtek RTL8139C PCI Fast Ethernet NIC Driver
- ASUS AMR driver
- VIA 4 in 1 Drivers (AGP, INF and IRQ Routing Driver)
- AMD Athlon AGP Driver
- USB patch file

A7V-M User Manual
quote:
From the manual
This motherboard uses only Dual Inline Memory Modules (DIMMs). (...)
Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 1GB.
(...)
This motherboard also supports NEC’s Virtual Channel (VC) SDRAMs.
(...)
SDRAMs used must be compatible with current PC133 SDRAM specification.
(...)
DO NOT attempt to mix PC133 SDRAMs with VCM SDRAMs.
(...)
DIMMs that have more than 18 chips are not supported on this motherboard.
(...)
ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.
(...)
Thus you need:
168-pin 3.3Volt DDR400 (PC3200 max)
unbuffered SDRAM DIMMs of maximum 512MB (with less then 18 chips on the stick).

The "TWINX" means that the memory module would have been sold in pairs of two! "TWINX" memory module pairs are selected and tested in dual channel motherboards at very aggressive latency settings for optimum performance and compatibility. The two modules are therefore an exact perfect match.
So you don't need to have "TWINX" memory modules, a non-TWINX will work also, but it wont perform as good as a matched pair. eg: one TWINX from one pair and another TWINX from another pair wouldn't perform as good either, hence they are sold per pair and not seperate.
