3/16 Update:
Still a couple of 320 left in I45N Houston.
I could not get the Celly D to work in the ECS 646FX-A. Took it to work and swapped out processors back and forth between a working P4 system. CPU appeared to be bad. Returned Tues. New chip does the same thing. Both retail boxes I got looked like they had been opened. Gal told me that they test them first. Whatever.
So started to scratch my head and looked on the ECS web site. Although the
]ESC 646FX-A rated for HT and 800FSB, it is
not Prescott compatable.
Further research revealed that
ECS 646FX-A2 is Prescott compatable.
I'd make two long trips to Fry's already, so I went to my local shop, which for me is
www.directron.com (can't go wrong there), and picked up an Asus P4S800 for about $15 more than the ECS. Same chipset, this time Prescott compatable. Lo and behold, it works straight out of the box.
P.S. Straight out of the box means 3.6G! with a small bump in voltage. Temps running low 40s idle and up into just over 50 under load. Which for P4 Pressys, thats about what it should be. No benchys yet, I'm still putting it together.
P.S.S. I was a Intel guys back in the Celly I 300A o/c to 450 days into the Celly IIs. But switched over to AMD XPs. So now, I've gone back to the "dark side".
