Tempest261 Posted March 17, 2006 Posted March 17, 2006 Can anyone explain why the 10.5 CPU multiplyer prevents my machine from booting, while multipliers 10 and 11 work fine? I've tried this with multiple FSB's within the 230-260 range. Each time I try 10.5, I have to reset the bios by popping out the battery or using the jumper method (if I can reach it). Any ideas?

coldpack Posted March 17, 2006 Posted March 17, 2006 always refrain from using half multipliers http://www.dfi-street.com/forum/showthread.php?t=20823 "CPU/FSB Frequency Ratio This is your CPU multiplier.. This times your HTTFSB is how you get your CPU frequency.. **Important note** On all a64 systems it is not recommended to use half multipliers ( i.e. 8.5,9.5,10.5) because this will put your ram on a ratio which means it will be running slower then you think and not the same as you have your HTTFSB set to no matter what.. A quote here from Wild shows what happens to your ram speed when using half multis… Quote:" Quote Share this post Link to post Share on other sites More sharing options...
Tempest261 Posted March 17, 2006 Posted March 17, 2006 Thanks for the unbelievably quick response. Ok, that solves that. So to get the frequencies I want, I'm going to have to turn up the FSB a lot. I've read the O/C guides and FAQ's, but I can't seem to find a "max reliable FSB" for the Expert. I know I'm going to have to find the true max FSB through experimentation, but I was wondering if you guys could give me a ballpark. (The MB chipset will be watercooled, if that helps any).

coldpack Posted March 17, 2006 Posted March 17, 2006 Head over the overclocking database. It contains useful setup information, just use the search function and your golden. http://www.dfi-street.com/forum/forumdisplay.php?f=28 Finding your max FSB shouldn't be TOO tough. Post your progress and i'm sure you'll get some useful information from the users here. Hopefully your charting your progress I was tempted to just start 'around the ballpark' of comparable setups to mine, but in the end, w/ the varying degrees of OC ability in different cpu batches, i've found to get the PINPOINT sweet spot OC.. u'll want to do everything from scratch. =) good luck. Let me know how it goes. Quote Share this post Link to post Share on other sites More sharing options...
