Yep, I have 1601 and run a 12x multi just fine, I can get it up to 20.

What "growing pains" are you talking about exactly... I've had zero issues with it and I can oc my memory upwards of 1000mhz, which I could'nt before... oh and 2004 killed my bios chip for some reason, Did a few benchmarks under that bios, failed a OC and it never booted up again... and a hot flash didn't work.
