New tool for undervolt/overclock AMD K8L and K10 processors

[gtrawoger]

@blackshard,

Here is the hardware list:

1x MSI MS-7228 VER.1.0 Motherboard
1x AMD Turion 64 - ML-32 - TMDML32BKX4LD
1x AMD Athlon 64 - 3000+ - ADA3000AEP4AX
1x Stick of 512MB DDR Memory

If you need a CD-ROM, HDD and maybe another MOBO (Soltek SL-K8AN2E-GR, needs new CAPS on power side of mobo, 6x 3300uF@6.3V) let me know. It will add to the shipping cost though, but not by much.

So let me know if you want the stuff for this project.

Oh, I forgot to mention, the MSI Board will take the Turion CPU. So you can test it on that.

Well I think the MSI mobo and the turion (or the athlon) would suffice. I already have tons of other components (ddr memory, HDDs and ODDs).

Can you, please, update me about the shipping costs?

[blackshard]

Stupid edit timeout: I can easily fix the Soltek mobo if you need the MSI for yourself.

Will it take the Turion?

[gtrawoger]

Yup, gotta hate the edit timeout. Anyways, nevermind the question. I will test it out myself (duh!).

I will get back to you.

I've registered in this forum to thank blackshard for this program. Now I finally can undervolt my Athlon 240e in Ubuntu x86.

I've compiled a Linux x86 version: http://dl.dropbox.com/u/2904420/Turi...9.1a_linux_x86 so you can add it to your tar.gz if you want.

Ah, and a couple of questions:

There's an easy way to set NB voltage? I looked in cfg file (in fedora bin folder) and i found:
# psmax <integer> - sets maximum pstate
#
# nbvid <integer> - sets northbridge (memory controller)
# voltage

But I do not know the integer value that I should use here.

I also found the psmax <integer> parameter. My processor has 5 p-states, but only 4 are active at the moment. If i set psmax to 4, can I activate the 5th p-state? Do I need to disable cpufreq for this?

Thanks in advance, and sorry for my english

I've got two questions:

There's an "easy way" to change NB voltage? I've looked in example.cfg and I've found this:
# nbvid <integer> - sets northbridge (memory controller)
# voltage
What I want is modifying NB(V) like in K10stat. But I don't know if this parameter will work for this. Besides, the value must be an integer, so I suposse that put 0.9750 is not an option. If I do the operations described in chapter 4:

vcore = 1.55 - (vid * 0.0125)
vid = -(vcore-1.55)/0.0125
vid = -(0.9750-1.55)/0.0125
vid = 46

Is that correct? There's a way to change NB(V) independently for each p-state?

Thanks in advance.

Hi Korso, unfortunately northbridge voltage and frequency is not yet available for K10 processors.

I planned to add support last week, but unfortunately the motherboard of the testing machine (a 6-core 1055T processor with a MSI-880GMA E45 mobo) I was developing on suddenly gave up during a stress test. Now I'm waiting for replacement that should come today or maybe tomorrow.

Hopefully I will add northbridge full support during this week with the release of version 0.30, so stay tuned!

I also found the psmax <integer> parameter. My processor has 5 p-states, but only 4 are active at the moment. If i set psmax to 4, can I activate the 5th p-state? Do I need to disable cpufreq for this?

Thanks in advance, and sorry for my english

Oh, I also forgot the second question

BTW, you can use the fifth pstate.
You first have to set psmax to 4, then program pstate 4 with consistent values, then you have to disable the cpufreqd linux scaler use the -scaler option of tpc.

Anyway I did the trick for those processors which have only 2 or 3 active pstates. Actually your Athlon II already has a sufficient number of pstates
