Linux substitute of A64 Tweaker?

post #1 of 15
Thread Starter 
I've installed a couple different distros of linux and cannot find a good substitute to "A64 Tweaker". Running under Windows, I run my Athlon 64 (sig rig) @ 1.175 Vcore @ 2.00ghz, and it runs nice and cool.
Linux however, runs at the stock Vcore (1.42v) and the fan is constantly throttling up and down to cool the cpu.

Anyone know a good program to adjust Vcore within Linux?

Another minor issue. Anyway to disable "Cool & Quite" under Linux?

*No BIOS options for Vcore or C&C*

Unless AMD has a tool they've released specifically for linux, without BIOS options I think you're out of luck to be honest. FOSS devs can do alot, but they're not miracle workers.

There might be a fan speed program out there somewhere, but I wouldn't hold my breath on the cool and quiet tool if I were you.

This only fixes part of the issue but for cool and quite you can adjust cpu frequency scaling with cpufrequtils. I believ it works with amd processors and you can set different govenors or a user space govenor that sets it to a specific speed.

There aren't really any Linux programs for CPU overclocking since they are all 100% motherboard dependent, and there are way too many motherboards out there. It's the motherboard manufacturers who need to step up and make these tools work in Linux.

As for Cool & Quiet there are a few ways to do it, such as cpufreqd, cpufrequtils, and maybe another one or two I forget offhand. Usually one distro will prefer one utility over another, so the "best" way might depend on which distro you have.

If you just want to change it temporarily, here's a nice command line:
Code:
for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor ; do sudo echo performance > $i; done

To turn it back on, do:
Code:
for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor ; do sudo echo ondemand > $i; done

I do remember using Cpufreq and one point in Mint. I cannot remember the command (cant find the page either) for it, but I could view the processor speed and the stepping for C&C. The commands you posted (error10) look close to the ones I used.
I tried to set all the C&C steps the same but I kept getting a message saying I don't have permission.

What distro would you recommend? I'm not too hell bent on overclocking. If I could set the CPU at 2.0ghz (stock speed) with lower voltage I'd be happy.

You've checked for the obvious, like BIOS updates, and getting a new motherboard? smile.gif

Believe me, I would love a new motherboard. Unfortunately I'm so outdated that a new motherboards means a new cpu, new ram, PSU, bigger case etc.

But, my BIOS is up to date and I can run crysis, lol.


Slightly off topic, but would anyone know where I could get a Linux driver for an ASUS EAH4670?

Get it from your distribution (you didn't specify). If it doesn't have packages, then get it from AMD.

Well disabling Cool & Quite was actually pretty easy.

*Linux Mint 10 32bit in Live CD*

sudo apt-get install cpufreqd

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

Set governor to "Performance" and its locked at 2.0Ghz wink.gif

Now If I can only get the Vcore lowered...

Well I was able to edit Vcore under Linux Mint as well. Win for me!

Stock voltage was 1.4000 and now its at 1.17500. Now it runs nice and cool.

Cpufreqd and Cpupowerd were used to achieve this.
