I don't know what this frequency is except maybe the speed between the the NB and the card. A friend of mine thinks that all busses need to fall inside the CPU>NB>HT(max)>PCI-e>SB frequencies. The Max HT for the MOBO is 2600 (3000MHz for the CPU). This means you would be lucky to find a HT freq of 2400MHz let alone 2600 MHz from a HT ref Clock of 200. More likely it will be less that 2400MHz. This means that the PCI-e frequency should be less than 2400MHz. You can set the HT freq to something less than your PCI-e, like twice your memory bus, but you want to keep the voltages at what you needed them to be at with HT Freq (Max). I am curious if anyone has stability tested a configuration like mine with a saturation of the CPU and the GPU. I am having trouble when I boot and the card is failing to initialize and when it does the PCI-e ref Clock has dropped from 100Mhz to 33Mhz. Could be a voltage problem in the board, but I am betting it is some kind of glitch setting the PCI-e multiplier to this almost crazy speed just under what is theoretically possible but drunkedly above how close reality gets to theoretically perfect. My friend wants to adjust the PCI-e frequency to 2200MHz, but we can't find a place to change it. The other culprit could be the voltage, but we do not know what voltage setting even affect PCI-e bus speed. If anyone has stability tested a MOBO with my configuration and you know your PCI-e Bus speed was 2500MHz, I'd at least know if I was right or not. My Friend and I thank you for your help resolving our argument. He won't let me use his memory to see if it is the problem 'til someone can prove the problem is not with the timing of the PCI-e Bus. Timing problems are intermittent without start up problems or load. Voltage problems show up at startup or under load. My friend said real overclokers use MSI, ASUS is becoming nothing more than glamour boards.
