If u were reading my post u can check it out and see that i don't have HTT 4x ... just 5x to 10x ...
1. Putting you full system specs in via the USER CP link would help us help you.
2. The HTT he was refering to (darn confusing BIOS terms) is regardine the RAM, not the CPU.
It utilize a 1-5 multiplyer to maintain a 1000MHz default speed with a 5x the RAM/CPU bus speed of 200MHz, so to keep that all stable drop to 4x for up to a 260 MHz OC and above that drop to 3x.
