My Motherboard (Abit AB9) is auto detecting it as 5-5-5-15 but it is supposed to run at 4-4-4-12 right? And I can go manually change this, but i also noticed in CPU-Z when I click on the SPD tab under Timings table it shows 266 Mhz- 4-4-4-10-15 and 400 Mhz- 5-5-5-15-21. What exactly is "Timings table" is this detecting what the memory should be run at? If so, shouldn't this memory be able to run 4-4-4-12 @ 400?
The SPD settings are just the recommended (conservative) settings from the manufacturer. The actual settings are under the memory tab.
You can go in the Bios and change those (manual setting) to the values you want.
You might need to change the voltage.
