A8N-E: Cool & Quiet
Just putting together my 3800+ dual core & a8n-e motherboard.
I would like to enable cool & quiet. Two things: a) Do i need to enable q-fan? Concern is that it is a competing technology and it doesn't mention requiring it in the manual. b) enable apic 2.0 support. the bios Power option just says apic support. i assume they are the same |

The way that works, is a thermistor inside the fan, measures the case air temperature. Between 32C and 42C the AMD fan might speed up, so if the case air reaches 42C, the fan spins at max RPMs. (I can find an AMD document recommending temperature controlled fans, but try and find a document that talks about what AMD ships with their PIB products...) Q-Fan is a control method based on measured CPU silicon die temperature. At 50C die temp, Q-fan delivers the full 12V. At lower temperatures, less voltage is delivered. Both of the above mechanisms can be combined, to give a wider operating range for the fan. But the question is, would you allow your case air to reach 42C ? That isn't the best for the disk drives, especially if the room air humidity is above 60 percent. (Disk drives have a temp/moisture spec - the main benefit of an air conditioned room is moisture reduction. A humid day in summer, in a dwelling with no humidity control, is not good for a computer hard drive.) APIC stands for advanced programmable interrupt controller. The APIC hardware in a computer, allows IRQs to be steered to multiple processors, like on a dual processor board. PIC is an earlier version of hardware standard for handling IRQs. Some chipsets have broken APIC implementations, and that is a good reason for having a BIOS control available to disable usage. In Linux, there can be a boot time option like NOAPIC, that can do something similar. I believe, for example, that NForce2 has a problem with interrupt storms in APIC mode (claimed to cause time keeping problems). ACPI is Advanced Configuration and Power Interface. I believe the BIOS can pass some ACPI hardware information in the tables it hands the OS at boot time. That can be used to access FID/VID, for runtime power control, among other things. ACPI spec also defines power states, and what to do hardware-wise during S3 suspend to RAM or S4 Hibernate. Changing support from ACPI 2.0 spec to the previous version, is probably changing the format of the table passed to the OS. APIC: http://www.rojakpot.com/showFreeBOG....ang=0&bogno=47 BIOS options explained: http://www.rojakpot.com/freeBOG.aspx www.acpi.info is not responding, so this entry will have to do: http://en.wikipedia.org/wiki/ACPI You can look at an archived copy of the acpi.info site here, until the real server is available again. web.archive.org links will be broken, and some clever copy and pasting of portions of URLs, is necessary to navigate the web sites archived. This happens, because no human can keep up with broken links on millions of archived sites. http://web.archive.org/web/200411170...www.acpi.info/ HTH, Paul |

I don't think I've had any trouble with it but if there's documentation for what you say, I might disable it. "Jody" wrote in message .. .

Some people have experienced crashes if their system is not configured properly. If your system is configured properly, you will not have any crashes. I have been running C&Q on a A8N-E with a 3500+ Winchester for about 10 months and it is rock solid. |
