Topic: UBNT RS Pro Overclock to 800MHz

Anyone knows how to overclock the RS Pro to 800MHz?

Re: UBNT RS Pro Overclock to 800MHz

Find proper offset and enetr proper value into bootloader.

http://svn.dd-wrt.com:8000/dd-wrt/browser/src/router/services/tools/overclock_routerstation.c

Offset: 0xd3 or 0x3f (depends on bootloader version), value: 0xf or 0x1f

Re: UBNT RS Pro Overclock to 800MHz

Hi guys
I have bougth a rs pro, it clocked at 720Mhz by default.

Now i wanna overclock at 800Mhz. How is possibible know a revision of redbot for correct ofset?


*I have opened this request
The similar file for fonera (It use RedBoot as bootloader and architecture is AR2315  ) was modified for to use with open wrt...

Is possible "convert" overclock_routerstation.c for openwrt?

Re: UBNT RS Pro Overclock to 800MHz

Set it in the bootloader...

Hi,

How i  can read version of redbot?

How set new hex value in it?

I rebuild the application without nvram and have tested it with a Meraki mini as well as an EnGenius ECB3500. I've only tested it @200mhz and reverting to stock. I'll look into submitting it as a package. Once I get a new RS I was going to build the appropriate one for that as well.

Re: UBNT RS Pro Overclock to 800MHz

Hi, any news with topic?
I am also interested in this.

Re: UBNT RS Pro Overclock to 800MHz

..Nothing,
Under dd-wrt there is "overclocked-service", while there isn't  similar package for open -wrt / Deb-wrt,

"Jonman409" has adapt a C code developed for dd-wrt for use under openwrt, but this is only for Ar2315, such as fonera. If you read this replay, you can send me your compilated code?

For router stations need to identify one's bootloader version for re-write hex value, as reported by  "obsy".

How do it? I don't now??

If anyone has done it, you can write a wiki? or how to??

Too bad :-( Hope someone will make the magic happen!

I wanna set cpu at 800Mhz, how do it ?  or is mission impossible....?


From DD-wrt source code here

Re: UBNT RS Pro Overclock to 800MHz

just some cents from me since i wrote this code originally. dont expect that 800 mhz runs stable on all rspro devices. i have seen temperature problems on some. for my own curiosity the original rs (not pro) does not that have that much problems with overclocking. originally i wrote this code to set a lower clock than 720 mhz, since some users already had temperature problems with the standard clock rate. what you have todo to get my code to work in openwrt. simply add a small main function and remove the nvram stuff. simply handle it with commandline parameters. thats all. the rest is really plain standard. should be a job of 5 minutes for a skilled developer

Re: UBNT RS Pro Overclock to 800MHz

I have a DIR-300: http://wiki.openwrt.org/toh/d-link/dir-300  and I think redboot and his FIS partition is the reason why I cannot conveniently use mtd (http://wiki.openwrt.org/doc/techref/mtd) to reflash.

Is my assumption true?

Re: UBNT RS Pro Overclock to 800MHz

sure you can use mtd. i see no reason why you can't use it in that way. for sure you need to setup a correct partition layout within redboot. for perfect reflashing its also good to set the checksum to zero before flashing. so redboot will not check the partition checksum

Re: UBNT RS Pro Overclock to 800MHz

OK, I adapted the dd-wrt code to work with openwrt.

See below for the source code

How to use:
just scp the file in /tmp
make sure it is executable: chmod +x /tmp/overclock_routerstation
/tmp/overclock_routerstation mhz
where mhz can be: 200, 300 ,333, 400, 600, 680, 720, 800

Please, consider I have not tested it because I don't own a RS neither a RS PRO, so use it at your own risk, you may brick your board!!!

have you compiled yourself the code or used the compiled one?

it's was the compiled one - still: Clocks: CPU:680.000MHz, DDR:170.000MHz, AHB:85.000MHz, Ref:40.000MHz

How do I compile overclock_routerstation.c with a trunk build environment ?

Hi, tongue

You can share your code in new ticket??

Someone can be make a patch for adding your code in system target for routerstation.
