I have found that PC m/boards using DDR memory can be very sesitive to the memory on board. Ideally all the memory modules should be of the same manufacturer and type(2100, CAS
, etc.) but if good quality (well known) manufacturers are used, it is usually OK.
I used a Samsung and Twinmos modules together and had to set a lower memory performance level in BIOS
- back to default. You might like to try this.
Press the Delete key while booting up and find the memory performance setting. This is different for different Bios
makers. Reset to default.
If it is already on default, you might have to try and get identical memory modules - or at least change the last one that gave you the problem.
Some people have reported that rearranging the memory in different slots can help.
