The 48Mhz sd hack is in the kernel. It is also noted, in OS2008, you have to turn off the cpufreq to get it to the full speed.

Thanks for the reply qwerty12. So that sucks then about the cpu freq down for sd speed. So with all of the hacks you have on your NIT, what speed is your sd card with this benchmark?

Is there a program where I could toggle the cpu in favor of sd speed? Maybe an auto throttling background task?

I wish I had all those hacks back . I'm still recovering from flashing.

You would have to flash Fanoush's kernel (either from his website or the one in the rotation thread if you like rotation too, fanoush's one, not jott's one)

Then you can echo these as root:
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 400000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

That will make the cpu run at it's full speed and bring the battery down.

To bring it back to normal;
echo 165000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

I just received a class 2 8GB SD card so after hacking, I'll post the speed of it

qwerty12,

Man, you have made a happier person with information. The whole device is snappier and more usable at this point thanks to the speed up. I'm leaving the system in the faster speed because it really hasn't diminished my battery life much at all from a normal days use. But, the speed difference is there and makes things a little more pleasant. Thanks again. The NIT also just seems to run aplications faster such as my emulators and normal web browsing. Maybe it's a placebo but I'm think that since the unit doesn't auto-throttle the processor, it just allows a smoother/faster day to day operation.

Here are my new results after running the two command lines from Xterm:

/dev/mmcblk1p1:
Timing cached reads: 204MB in 2.01 seconds = 101.25 MB/sec
Timing buffered disk reads: 26 MB in 3.00 seconds = 8.66 MB/sec
/dev/mmcblk1p2:
Timing cached reads: 200MB in 2.00 seconds = 99.95 MB/sec
Timing buffered disk reads: 38 MB in 3.00 seconds = 12.66 MB/sec


My old numbers (For reference):
/dev/mmcblk1p1:
Timing cached reads: 194 MB in 2.00 seconds = 96.42 MB/sec
Timing buffered disk reads: 10 MB in 3.18 seconds = 3.14 MB/sec
/dev/mmcblk1p2:
Timing cached reads: 192 MB in 2.02 seconds = 95.27 MB/sec
Timing buffered disk reads: 14 MB in 3.03 seconds = 4.62 MB/sec

not totally related....but sorta is....i tested using hdtac the internal drive on the n800...only got 5 mb/s but whence on an external reader the same card got 20.2 mb/s my version on the about product is 2.2007.51-3 didnt run the hdparm yet

That looks like a good setup. When you do get hdparm on your device and test it, please post what you find. I would like to know if it reports these same smoking speeds.
