It stays relatively cool under load. It helps that most of the casing is aluminum. Should i be lapping my battery cover and applying thermal paste/pad? Nah, but that would be funny. Strange thing is that 2016 is unstable, even with an additional 25mv bump in vcore. I only clock that high when i can make use of it. I disable scaling becauase the switch time of the vdd and clk is not specific to upclocking or down clocking. So, when you drop down to 245mhz from 1996mhz, the vdd drops first, couple microseconds after, the clk follows.. see the problem there? This scenario is fine for upclocking, as it gives the vdd time to stabilize before cranking up the clock. But reaching the vcore of 245mhz before switching the clock from 1996 is a guarenteed lock up.

So yeah, need upclock/downclock specific values for vdd_switch_time and acpu_switch_time.

I'm happy with having a big boost in perf when i need to tar xjf *backups. Doesn't seem to do **** for the awful io perf (relatively speaking, its great.. for a phone). It just frustrates me that my disk speed is the bottleneck when downloading something (C6 SDcard too). Turning the wifi PM off seems to help with large cifs transfers (iwconfig eth0 power off). The same holds true for broadcoms desktop linux driver. But I digress. Yep. 806->1996.8 .. that beats my old opty 165..

Desire HD at 1.2 ghz here. Leedroid v1.4 custom kernel. Undervolted and with Leedroid smartass governor mods it's so sweet on my battery.

You can pull the git tree for the cyanogenmod desire kernel... then open up arch/arm/mach-msm/acpuclock-scorpion.c - Find this "struct clkctl_acpu_speed acpu_freq_tbl[]" - or something like it.. It'll stick out because it will have the list of frequencies.. The voltage is set in mV, I've never seen anything else.. There usually are voltage limits that you will have to modify elsewhere.. usually in board-[devicename].c

I'm basing this off of my experience with the HTC HD2... which I believe has the same processor as the Desire.. The desire does seem to clock better.. The freq you are looking for is 1305600.. above that is 1344000,1382400,1420800, and so on.. Although I wouldn't try anything past 1420800..

Is there anyway to get my milestone to scale between clocks better? I.E go up in steps rather than jump directly between the maximum and minimum.

I've currently got it going between 1.3 and 0.8 Ghz.

Get a different kernel maybe and changed between ondemand to conservative maybe in SetCPU? It's been a while but that's what I roughly remember. Some kernels allow more options to play with in SetCPU.

You may be using the ondemand scheduler with the kernel option CONFIG_CPU_FREQ_GOV_ONDEMAND_INPUT=y . This option cranks the cpu up to max clock whenever an input is detected. This could be a power button, hardware keyboard, etc.. any input. It makes sense to a certain degree - as responsiveness is important, but with your min/max settings.... probably no point as 800mhz should show no lag upon initial input (such as the beginning of a scroll down 'event'. If your min speed was 240-something, then having that option turned off could cause some initial lagginess if the scheduler wasnt configured aggressively.
