What I am not understanding from the OP is how to get it from stock parameters to 1.3 and to edit the voltage. I just don't wanna run commands and not know.
You have to edit the setscaling.sh. Here's an example file, which would run the phone at 400/700/900/1100MHz (1.1GHz max):
Line 1 is the maximum voltage the phone will pass to the CPU.
Line 2 is the maximum CPU speed.
Line 3 through 6 are different CPU speed in Hz (from idle up to 100% usage) with voltages (the secondary two-digit number).
Line 7 through 10 are the same CPU speeds in kHz (minus the last three zeros from lines 3 through 6, to put it simply). Note that they are in reverse order. I would assume this is due to how the OS reads the mpu_opps table vs how it reads the freq_table.
What values will be stable for your phone will depend on your individual handset. Just like with a desktop CPU, each handset's CPU is slightly different and will handle overclocking better or worse at different speeds/voltages.
Nice, did you make any other changes? I can't get 1.3 at all. I've tried voltages of 61,62 and 63. As soon as I execute the script, BAM! hard lock.
EDIT: Paste you setscaling100 script.

PERFECT! That's the link up I needed. For some reason my brain wasn't thinking to edit the file itself, but to enter commands.
I haven't edited files since one of the earlier 2.1 bugless beasts on the D1, and that was one time to remove some included scaling parameters.
Thanks!

omg how are you guys doing that!!! mine just stays at 1000mhz after running the commands. i wanna know the same thing inssane wants to know.

Yeah I had to run 1.2 at 59 but that's number basically is an amount of juice your phone sends to your cpu at that speed. That's why you don't want to go to high and if you drop it to low you can get reboots. Thus look for excess heat which could indicate your sending much power to it. Lockup and instability could mean not enough juice or your just running it to high
I know what the setting/number does, what I'm looking for is how it correlates into voltages. Obviously we aren't pumping 59 volts into our phones, lmao.
The CPUs most likely have a base voltage and the numbers we're using in the script are likely +mV values. At least that would be my guess.
echo 56 > /proc/overclock/max_vsel
echo 1300000 > /proc/overclock/max_rate
echo 1 300000000 27 > /proc/overclock/mpu_opps
echo 2 600000000 38 > /proc/overclock/mpu_opps
echo 3 800000000 50 > /proc/overclock/mpu_opps
echo 4 1300000000 63 > /proc/overclock/mpu_opps
echo 0 1300000 > /proc/overclock/freq_table
echo 1 800000 > /proc/overclock/freq_table
echo 2 600000 > /proc/overclock/freq_table
echo 3 300000 > /proc/overclock/freq_table
Just noticed my max is still at 56 this phone must be a beast

ah well
.... even after this, i do not get it at all. guess i will have to wait for something simpler. Wow wtf?! Hmm, you did up the other values as you went up, unlike me. Maybe if I changed mine too it would work. (ie. echo2, echo 3 etc)
Gonna test now.
EDIT: WOW! A 1678 quadrant @ 1.2Ghz, damn. This phone is a beast.
If you're only increasing the maximum frequency (lines 2, 6, and 7), then you only need to increase the max voltage (line 1) and voltage for the maximum frequency (line 6). Increasing voltage to the intermediate speeds without increasing those speeds really doesn't do anything except stress the CPU harder when it's trying to relax.
Right, but I wasn't refering to changing the voltages. I was refering to the different speed steps. He changed his speed steps when he went to 1.3, where I did not, I left them at what they were for 1.2. But I think I found the problem, it was something else I missed.
EDIT: Ok I got 1.3 running nice and stable. Walcs, can you please tell me your voltage max for 1.4? Thanks ahead of time.
Also, why the hell did this forum disable tapatalk? What a pain in the ass.
I'm also curious as to what voltages people are using for 1.3 and 1.4GHz. Right now I'm running 1.2GHz @ 59. A 470 second stress test hit 38*C max (while charging) with no errors. My Quadrant scores (my usual triple test) were 1708, 1632, and 1622. I'm not sure where that 1708 came from because I haven't been able to duplicate it.
Also, does anyone know what kind of maximum temps to avoid? I don't have much specific knowledge of the Droid hardware or ARM processors in general, and I really like to know my boundaries before I do too much.

I have had several D1 replacements and I have had ones that could run 1.25 std voltage - 1.2 ultra low voltage, with no issues.
Sometimes it was the ROM that failed on certain kernels and sometimes the phone. I had one phone that couldn't go past 1ghz and another that could only run standard voltage at 1.1ghz.
I am looking at the 1.4 quadrant and my pants just got tight, lol.
Can't wait to get home and do this - no time to do it at work, even though I could.

Do not past 96 vesels, see my Quadrant score above
Thanks bro
Yeah, like I said, my pants got tighter, lol
True test will be stability, heat, and battery life - in that order.
I was getting low 1700s at 1.2 with my D1, I am hoping to see much better than the current 1400s.
-Thanks for the voltage max
