Why is my bclock high?

post #1 of 15
Thread Starter 
Earlier, when I looked at CPUz and saw my bclock, it was around 99.8 mhz ( my bios said it was 100.0) but now it says 100.3 mhz. Is there anything wrong or bad with this. (I never changed any setting in the bios for my bclock)

Thanks. I know I sound like a dumbass, but it it's my first build so I'm just nervous.

You BCLK was probably at 99.8 MHz because you have spread spectrum enabled. If you disable it it should stay at an even 100 MHz and not variate.

What is spread spectrum?
post #6 of 15
Look in your BIOS, it should be there. If it is on and changes the BCLK you should turn it off, but otherwise it can help with stability.

Is it any thing like LLC or something like that?
post #8 of 15
No, LLC is for reducing vdroop, and it doesn't change anything related to the speed. You should probably put it at 4 or 5 to eliminate most vdroop without causing spikes.

IIRC spread spectrum has something to do with electrical interference, if enabled it can help, however for older gen chip, it was recommended to disable it for stability. For sandy brisge, it is recommended to leave it on unless you're are messing around with the bclk or if the bus speed is showing a lower value than 100 (99.8 etc).
