Question for you: my QX9650 would pass at 5400 but was scoring lower than my 4.8GHz run. Were you having issues like this as well?

No, I haven't issues like that.

BTW Your QX9650 is quite nice Mine wouldn't pass 5200 MHz

5375 is pretty close to the max for an average chip. I was able to do 5460 on mine but not a cent more. Also, CB doesn't react much to memory on these older platforms. Mine was loose as hell at 840 9-9-9 24. I wanted all stress off the NB so I could push the core without any worry.

Great sub ivanov

It's deceptive how difficult this stage was!
