I read this http://www.legitreviews.com/article/373/3/ and few other articles and decided to try OCing my 4200 x2 CPU a little. Lowered the multiplier to 4X, increased CPU clock to 232 mhz and got a nice OC of 2552 mhz compared to the stock 2200 mhz. After a few hours though got a blue screen, memory dump, etc. Should have read in more detail but didn't. Anyway, now I lowered my clock to 225 and the processor is running at 2475 mhz. I don't want to change any voltages, just looking for an overclock of up to 20% if possible. I wonder if anyone knows how to change the CPU/memory ratio. I'm running 2 X 1 gb of PC4200-533 DDR2 and at 233 mhz the CPU-z tool showed the memory was at ~ 284 mhz, a little over the 266 mhz rating. If I could use a 6:5 ratio, I'll be able to bring it down to 236 mhz and potential avoid the crash. Problem is, I cannot find any option in the OC menu that lets you play with the CPU/memory ratio. So if anyone has experience with this type of motherboard and can offer some advice, it will be greatly appreciated!
