The Mother Board

[Karlsweldt]

Re useit:
Please post the specifics of this system, for a better diagnosis and suggestions.

Memory, if installed as one module, must be in the first-detected slot, typically the "bank 0, slot 0" position. Some oddballs require a different option. Best to read the user's manual. For very old boards with SIMM modules, many required two modules in the 72-pin or four modules in the 30-pin versions. Modern DDR memory requires only one module, if a single-channel setup. Can also be applied to multi-channel setups, for testing.
As to older systems, they may recognize only single-density memory setups. High-density modules would show only 1/2 the true module capacity, on the POST pre-boot screen. Whether it be single-sided or double-sided modules on a memory card, does not indicate the single-density or high-density status. The logo on the chips and the module tag have the info for research.. and usually the status.
When mixing modules of different speeds, it is important to put the slowest module in the first-detected slot. This sets the speed for all modules. Faster modules will clock back with good stability, but slower modules will falter at higher speeds. With multi-channel memory setups, you must have the identical memory amounts in all channels.

SDRAM is single channel. So you can run the board with 1 stick of memory and it will run fine.
I wouldn't mix single and double sided dimms. That will probably cause issues.
And you can run different speeds (PC66, PC100 and PC133), but the slowest stick will slow down all of them.

What CPU are you using? Because I think this board can only do 1:1 FSB/memory speed so if you have a 133MHz FSB CPU you need to use 133MHz DIMMs _only_

Next this VIA chipset only supports low-density DIMMs, in the same fashion as the Intel 440BX chipset. For rules on what DIMMs to use, see here:
