Quoting MediaMan
GHoosdum,
Okay...did some poking about and I've got real answers for you.
- C'n'Q requires logic (HW) on the CPU chip itself to support, and yes... this has been implemented in all Athlon 64 desktop processors
- C'n'Q requires corresponding motherboard logic (HW) to support the functionality... that's up to mobo vendors, but I think you'll find most supporting it
- PowerNow! is the technology for the mobile segment and yes, it requires CPU and mobo logic (HW) support as well.
I don't think it's possible find any K8 laptops that do not support PowerNow! Check your power settings... it's probably locked in "Max Battery" or "Presentation" mode. Select "minimal power management" in the power settings tab which puts C'n'Q in automatic mode... just like PowerNow!
Keep in mind that C'n'Q and PowerNow! do not affect the speed of the HyperTransport link operation, just the CPU multiplier used for frequency determination for the processor.
Thanks for digging up the info, MM. I'm sorry that I forgot to mention at first, it's not just me having this problem. So far, every A64 notebook I've seen has had the 800MHz on battery issue. Supposedly, manufacturers need to release a BIOS update. I think. There were also ramblings that it's a Microsoft issue, since the speed will step up to full on an A64 nb in Win2K, but not XP.
