QPI Frequency

post #1 of 3
Thread Starter 
Ok so I know that QPI Frequency is related to BCLK through a multiplier, but in my bios my QPI Frequency choices are strange. They are 4.440GT, 5.180GT, 5.920GT,6.660GT,7.400GT, and 8.140GT.

Further, I'm trying to maximize my BLCK and I hit a wall at 185. I then noticed that this QPI Frequency was set at 8.140GT, so I lowered it to 4.440GT to see what would happen. I WAS stable at 185 mhz, but lowering that frequency made me fail POST. Can anybody explain this?

It sounds like the bottom setting was the "slowest" setting, have you tried say a 5.180GT, also, at lower clocks the QPI doesn't need to be on low clock settings.
