Linuxhelp _ Hardware Support _ AMD 4200+ - Underclocked :(

Posted by: matt Dec 19 2006, 09:35 PM

Hey Guys.
Just picked up a new pc. Its a Acer Aspire E380. Dont really like acer. But I got the system for just over 500 bucks which isnt bad for a AMD 4200+ Windsor AM2 . Problem is my cpu is running at 1ghz and theres no way to change it in the bios.

Is this normal for this processor, Its supose to be clocked at 2.2 If im not mistaken!
Any hardware Ideas?

Hi,

I myself have a Amd X2 3800+ , with a DFI Lanparty UT-4 NF4 Ultra-D mobo, it works now at 2400Mhz overclocked....

My idea is that maybe you should check in the bios somewhere for a Cool and Quiet option, and disable it, maybe that is the thing that is underclocking your cpu when it's not used.

Awesome, It turns out to actually be the cool and quiet function.
Cpu is now running at full speed!

Question, How stable is the cpu at 2400Mhz, and is this using the default heat sink?

Hello,

I'm using a Gigabyte rocket cooler 3d pro heatsink, it's this new phase colling thing.

At 2400 mhz it's ROCK SOLID. the max speed I got when I bought the system was 2700Mhz, it worked
at 2700 mhz no problem for over 6 months, after that it wanted more vcc , and eventualy I had to decrease the Mhz, I'm only using 2400mhz because my ram is not overclocker friendly I've got 2x1GB Kingston 400DDR ram.

The system is still stable at 2500Mhz and almost 2600Mhz but due to memory thing, I use 2400Mhz since this way memory operates exactly at 400Mhz DDR


Sincerely

ps.: you really can't kill a AMD X2 processor... just go up with the voltage... max would be around 1.65V don't go beyond that... at around 1.55-1.58 I should be able to overclock atleast 200Mhz if you are lucky.
If the processor overheats it just turns off... good thing this is. Same with my GeForce 7800GT card.

If you want to remain "cool and quiet" (and save energy) the KDE Power Save applet will scale your CPU frequency for you, as will the cpufreq-selector command.
