Problem overclocking 875A02-6EKRS mobo

post #1 of 4
Thread Starter 
I set the FSB to 233mhz and I set the ram frequency to 320mhz and it booted up fine but there was no sound. From what I've gathered, I need to enable the pci lock option but there is none for my motherboard. I've seen other people overclock this mobo to 233mhz without changing anything else and it worked fine. Can someone help me out?

Unfortunately, if you don't have a PCI lock, your overclocking options are limited. PCI frequency performs best 33.3 MHz. It will still function a few MHz above that, but anything over around 37 MHz can cause instability (37 MHz equates to around 225 MHz system clock). The folks you know who got to 233 MHz were probably just lucky. My suggestion would be to overclock slowly 2-3 MHz at a time until you find the point at which the lack of the PCI lock makes the system unstable.
