Keep the multiplier at 11x, if you put the HTT over 250, you're supposed to lower the LDT to 3x. Make sure you do one thing at a time, remove the RAM from the equation while you're testing your max HTT by dividing it. When you're ready to test the RAM's max, lower the multiplier and raise HTT, keeping it 1:1.
Here's my San Diego specs:
- HTT: 256
- Multiplier: 11x
- LDT: 4x (haven't had problems with it at 4x)
- RAM: 1:1 (DDR512)
- Voltages: Vcore = 1.5v / RamV = 2.7v
Hope that helps you .
btw, I play BF2 smoothly with 1 gig.
