ASUS is trying to fool us.

Ai Clock Twister Light is exactly the same as Ai Clock Twister Moderate and DRAM Static Read Control Disabled. It's exactly the same bandwidth in EVEREST.
I also tried Ai Clock Twister Lighter. It's also exactly the same bandwidth.

After many more tests I came to this conclusion. The memory is stable at DDR 1253MHz and tRD 6.

The CPU is stable at 4.23GHz.

The board fails to keep it stable.

BIOS 0902 is good but not good enough. The problems with the memory are fixed but there's still a problem with the BIOS that makes the NB fail after some time.


FSB 500MHz and my Q9650 ... not with this board and/or BIOS if I want it really stable.
