    Hi all, first time posting here.

    I just upgraded to 4gb RAM on my 1521 from 2gb. After I installed it I checked the <Properties> on XP to see if all the RAM was showing up, 3.37gb showed up. But I noticed the processor speed was down to only 795mhz, so I checked it with CPU-Z again and that read 795mhz as well. I went into BIOS and turned off the AMD PowerNow option and it bumped it back to 1.9ghz. I ran CPU-Z again and it was at like 1.895.2ghz, but i noticed the bus speed was down to 199.5 mhz. Shouldn't that be like 333 or something? I've attached some screenshots from CPU-Z after turning off AMD PowerNow, with PowerNow all cpu specs are much lower.

    I'm running XP pro SP 3 btw.

    The bus speed x the multiplier = core speed. 200 MHz X 9.5 = 1.9GHz. Your CPU is fine.

    Enable Powernow as well since that will allow for cooler operation and better battery life since the processor dynamically changes the clock speed between 800MHz and 1900MHz depending on load. But as atbnet mentioend your CPU-Z screenshots look normal and nothing to worry about. Your memory is limited by the CPU, so ~315MHz is the max speed you will get with DDR2 333(PC 5400) memory.

    45 nm has only been out for about a year now. I don't see how 65 nm is 'not good'.
