AMD or Windows XP problem?
Hi all,
I am pretty sure this is going to end up being a MS problem but here it goes. I just bought this new system: Asus Abit KN8 Ultra nF4 AMD Athlon 64 X2 4400+ Dual-Core 1MB 2 GB RAM DDR 400 Mirrored 250GB Sata3 drives Windows XP SP2 And for the life of me I cannot make the cpu top out. I tried using WorldCommunityGrid and the most I see (using Task Manager) is 50% CPU utilization. Is there something on the motherboard or maybe inside windows which is holding back the cpus from utilizing all the cpu? Any help would be appreciated. --LJ |

The AMD processor is far more efficient than Intel...able to execute more instructions per clock cycle. Add to that the fact that your processor is a Dual core, and you can see that it would be very difficult to tap out the processor. With PIII and P4 processors, because of their design and the fact that they still use the Northbridge chipset for all I/O, do not have hypertransport, etc...well they were easy to tap out. Intel procs have higher latency and can execute fewer instructions per clock cycle. What you are experiencing is by design and intent. Sit back and enjoy your new computer, safe in the knowledge that you have a great machine! Bobby |

You are still thinking with a single core processor mindset Your X2 4400+ is a dual-core processor! A single thread of WorldCommunityGrid will only run on and peg one core (so 50% total system load). Try running a *second* separate installation of WorldCommunityGrid at the same time and see what happens to the CPU utilization -- |

Bobby It has nothing to do with memory controllers, Hypertransport, or pipeline efficiency, it's solely due to the fact that there are two processors in an X2. One single threaded program can use at most 50% of the available cpu resources because it can only run on one processor at a time. To use more than 50% of the available cycles you would need to run at least two single threaded programs or one multithreaded program. |

Run more than just one program at a time.

See what happens when you disable Cool 'n' Quiet Control in CMOS (BIOS)
- Power Management Setup. |

This would have no effect whatsoever...Cool n' Quiet is an on-demand process, and does not cause any app to spike the CPU. Suggest you do a little research on the subject... Bobby |
