It has been asked here before with no answer. Any ideas how will this affect the coming PR1.2? Current fw version is shown to be unknown after the overclocking.
You musn't be afraid. If you want a secure PR1.2 upgrade, the only thing you have to do is reflash again the N900 with the stock kernel (600Mhz) and then, flash it with PR1.2

Also, I think there is no problem with flashing directly the overclock kernel with the stock PR1.2 since the update comes with a newer kernel version. Sorry if my English is very bad!

No, it does not affect emulators. It's utilized by some audio and video codecs and telephone stuff.

Also, the same indexes (selected by the mpu table) are used to access the mpu and the dsp tables, so they must be the same size (or use some other hack, as I did in the file resource34xx.c).
thanks. I missed the reference in smartreflex. The LUT seams to reasonable.
yes, my tables have the same size.

Re: Overclock the N900?
 
So I've been reading through this thread and I can't find the answer to two things:
How does it affect battery life? (as in, when idleing and so forth)
Does the flasher reset everything and delete all my apps (I know mydocs/calender/contacts will be unaffected since I already reflashed from the UK firmware to the Global one)

When you flash it with -k parameter (like is done in the guide of the post), you only flash the kernel, so, you don't loose any app. You only replace the kernel image. It is a transparent process for all the information stored in the N900. You don't need to reinstall anything and all your information is going to be like before flahsing.

unsure about batt life, it idles at half speed now, and some ppl think that the fact the higher mhz will posibly help batt life too as calculations will be done quicker.
obviously if its maxed out for long periods it will adversely affect battery

the flasher does not reset things, it only takes a couple of seconds and just turn the phone on and run conky to see new mhz.
