My nforce2-board (N2U400) can bring the clock down, but not bring it up again.
It freezes when I try so.
Has someone a hint? _________________ Just unused Microsoft-Software is good Microsoft-Software |

Cpufreq seems to work nicely or atleast I think so. When I set my fsb to minimum the CPU MHz in /proc/cpuinfo doesn't update, but the bogomips drop 4400 to 3300. So I think it works.
On the other hand atxp1 doesn't work at all. I get kernel oops when trying to change the voltage. Dmesg shows this when I load the atxp1 modules "atxp1 2-004e: Using VRM: 9.0" There's no " .... atxp1: Detected on SMBus nForce2 adapter at 5000, address 0x37" like in the first post of this thread.
I use 2.6.13.2-nitro1 kernel and atxp1-0.6.
Here's the oops

@Jinidog: What's your Boot-FSB and your lowest value?
@Jase: cpufreq should update /proc/cpuinfo...hm. The "Detected on..." message was removed. Also they changed somewhere between 2.6.11 and 2.6.12-13 the sysfs-interface ("warning: initialization from incompatible pointer type"...not good), so it will crash if someone tries to write to the device...
Have you checked if the ATXP1 module is maybe already in your kernel? |

I have a AthlonXP 2800+.
Normally it runs with 2070 MHz and I can scale it down to 1512500 Hz. _________________ Just unused Microsoft-Software is good Microsoft-Software |

Yes, it wasn't there so I patched the kernel. The patch applied with some minor changes. I'll take a look at the sysfs changes and try to solve it by my self. I just didn't know where to start from. Thanks anyway. _________________ Desktop gallery |

I forgot to ask.
does anyone have 8rdavcore for linux. They released a 0.5.5 version , but after GPL problems it has disappeared and i can find nowhere. |

8rdavcore 0.5.5 was a userspace ATXP1 driver. Since there's now a ATXP1 module for the kernel the old cold isn't required any more. Maybe when I get the time I'll finish the successor of 8rdavcore, which will run on linux. |

wow that was fast, thank you!
edit: btw: PrakashP, I'm not good with ebuild, how can I use your cpufreq patch? http://punnoor.de/nvfreqd/nvfreqd-overlay.tar.bz2 <- is it this file? Thanks in advance!
so should I worry about:

Hi there
I have been playing around with cpufreq-nforce2. It has great potential, but I am not satisfied yet
On my ASUS A7N8X-X, I can bring my Barton 2800+ (2083 = 12.5 * 166) down to 625Mhz. But I can not bring it up again. When I cross around 1000MHz on the way down I cannot go up again.
Scenario: From 2083 -> 1500Mhz -> 1200Mhz -> 800Mhz -> 625Mhz -> 700 -> 800 -> 900 -> 1000 -> 1100 -> 1200 -> 1300 -> 1400 -> boom (1500)
Scenario: 2083 -> 1600 -> 1200 -> 1600 -> 2083 totally stable
Scenario: 2083 -> 1600 -> 1200 -> 1000 -> 1200 (boom)
I then tried another board. Aopen AK79D-400VN. There I can do whatever I desire, but the MHz does not go down in /proc/cpuinfo ALTHOUGH the bogomips does!!! The bogomips value gets updated, but the system remains at 2083. I then tried another CPU. Same deal. I don't get it. AK79D-400VN is listed as supported. I can see that other ppl in this thread have had simelar problems.
Any clues? Ideas? solutions? Ohh yes, stock voltage, no overclocking, no out of bounds on ram and so forth, and the latest 2.6.14.2 kernel.
Regards Thomas, Denmark |

That would be really good... I had all this working perfectly on my 8rda+ but have since replaced it with an abit nf7s-v2 which it won't work with (crashes when increasing voltage after lowering...) ![Sad :(](images/smiles/icon_sad.gif) _________________ A few months struggling with gentoo is better than a lifetime struggling with windoze! |

Hello !! Sorry for my very poor english.
Could you tell me which version of bios you use in yours 8rda+, because on my computer (gentoo,8rda+) cpufreq works but I can change FSB only with 20Mhz. If I have default FSB on 200 and I change to 180 everything ok, but
cpufreq-set -s 1700000
makes my gentoo halt immidietly
I use 2.6.14.3 |

Hallo,
I'm using an Epox 8RDA6+ Pro with Mobile-Barton 2500+ and changing FSB and voltage is possible and work fine, but I can't go below 1.325V. When I set Vcore to 1.300V the system hangs. I think 1.100V must be possible. What is wrong or has anybody an idea?
Thanks! |

Hmmm, autocpufreq scripts lowers voltage and cpu frequency when run but never raises either again. It is as if it doesn't realise that the cpu is at 100% load... Anyone else experience this? Doing things manually seems to work ok now... _________________ A few months struggling with gentoo is better than a lifetime struggling with windoze! |

Anybody can change vcore in an Abit an7 mobo?
I can change the fsb, but not the vcore, so the temperature don't down
I think this is about uguru chip, that i can't see voltages or temperatures of my mobo. _________________ AMD Athlon XP-M 2500+ @2200MhHz|1GB DDR @400MHz Dual-Chanel|NVIDIA GeForce4 MX 420|SB Live 5.1|ADSL 512/128 Arsys

Hi, is there any way to manually change the maximum_fsb frequency so that it is above the boot_fsb? The only option I see is the min_fsb=..
I have got a shuttle an35n ultra and I want to scale from 66Mhz to 200Mhz Fsb. However if I boot at 200Mhz it only goes down to 150Mhz. If I boot at 133 Mhz I am limited to an 133Mhz maximum but can scale down to 66Mhz. Using 8rdvcore in windows only booting at 133Mhz I can scale from 66 to 200 and back without any problems. Any recommendations? Unforunately I know nothing about programming so I don't have the knowledge to modify the cpufreq-nforce2 source. |

Did you ever figure thisout? I have the same issue. 9191-0290 and cpu0_vid shows 1750 but I cannot modify it. This is a NF7-S2. |

|

I can setup the most modules and use the cpufreq-nforce2 for changing my CPU-Speed.
If i load the modules for atxp1 it says:
cpufreq: Detected nForce2 chipset revision C1
cpufreq: FSB changing is maybe unstable and can lead to crashes and data loss.
cpufreq: FSB currently at 100 MHz, FID 10.0
i2c_adapter i2c-1: nForce2 SMBus adapter at 0x5000
i2c_adapter i2c-2: nForce2 SMBus adapter at 0x5040
in your Howto it should be like that with dmesg:
atxp1: Detected on SMBus nForce2 adapter at 5000, address 0x37
after loading the modules I can see in the location /sys/bus/i2c/devices/9191-0290
all neccesary files and read out the /in1_input, but even with setting the file-rights correct
it is not possible to change the volt.
in my bios i set the core volt at 1.6
on my motherboard is a chip its named attansic so i expected this to work
my linux is gentoo, kernel 2.6.16
may be anyone of yours find some mistakes here
thanks |

i can see the vcore:

1850 |
(it's correct because overclocking)
but i can't change it
Code: | root@pcluisfe linux # echo 1750 > /sys/bus/i2c/devices/9191-0290/driver/9191-0290/cpu0_vid
bash: /sys/bus/i2c/devices/9191-0290/driver/9191-0290/cpu0_vid: Permiso denegado |
Any idea?
Mi pc is an athlon xp barton mobile 2500+ @ 2000Mhz in an Abit an7, with fsb 400 |
I've had similiar problem. I couldn't change Vcore through /sys/bus/i2c/devices/9191-0290/cpu0_vid but it is possible to do that thorugh /sys/bus/i2c/devices/0-004e/cpu0_vid. I have nf7-s board but i think it doesn't matters. |
