I have this M/B and it isn't working as well as I first thought. I'm running the e4300 with the 200 fsb. So far it seems to stop at 261 or 262 FSB. Every time I clock over that it fails boot until I get to 266MHZ where it seems to reset the clock back to 199mhz for a cpu speed of 1.795GHZ. This is with ddr1 or ddr 2 memory. So when I set the FSB as 300 cpu-z shows 225mhz. Only 25 over stock.
FSB as set----as measured by cpu-z------- cpu freq.-----mem latency
250 -------------- 250-------------------------- 2250 ----------3 14
266 --------------- 199 --------------------------1795 -------- 3 15 179
267 --------------- 200.2 -----------------------1802---------3 28
274 ---------------205---------------------------1849--------- 3 15
285 ----------------213-------------------------1923----------3 24
300 --------------- 225-------------------------2025----------3 15 165
See how the clock reverts at around 266. Any one have an idea why this happens?
Performance tests seem to prove the measured speeds over the speeds set in the bios.
