Overclocking

Hi,

If we are already trying to make a lot of fun MODs, then the Overclocking MOD has to be one of them....right  wink
So i decided to google around and found a reference here ( http://midge.vlad.org.ua/forum/viewtopic.php?t=603 ) and decided to try it out....
This is what happend:

I made a boot log before doing anything.
It looks like this:

Code::

ADM5120 Boot:
no sys signature found!!

jump to linux code!!

LINUX started...
ADM5120 Demo board
CPU revision is: 0001800b
Primary instruction cache 8kB, physically tagged, 2-way, linesize 16 bytes.
Primary data cache 8kB, 2-way, linesize 16 bytes.
Linux version 2.4.32-amilda (root@osamabinary) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110.1)) #4 Sun Sep 10 11:08:13 PET 2006
adm5120_setup() starts.
System has no PCI BIOS
Determined physical RAM map:
 memory: 00cda000 @ 00326000 (usable)
Initial ramdisk at: 0x80208000 (1007616 bytes)
On node 0 totalpages: 4096
zone(0): 4096 pages.
zone(1): 0 pages.
zone(2): 0 pages.
Kernel command line: load_ramdisk=/dev/ram0 root=/dev/ram0 rw console=ttyS0
CPU clock: 175MHz
Using 87.500 MHz high precision timer.
Calibrating delay loop... 174.48 BogoMIPS

and then did the folowing:

This is my BR-6104K before i started to rip it apart and unsolder/solder things around like wild  big_smile  lol

http://downloads.amilda.org/MODs/Overclocking/after.jpg
And this is my BR-6104K after i calmed down from my unsoldering/soldering wild blackout that lasted about 1min  big_smile

What i did is to unsolder the R89 (1kOhm) and solder it to the empty R88......and that's it...it's like a jumper, but only with resistors.
If you have trouble to desolder the R89, you can use a small and very sharp screwdriver to VERY carefully scratch the resistor from it's place, and then just solder it to the empty place R88 right next to it.

Oh...the log after:

Code::

ADM5120 Boot:
no sys signature found!!

jump to linux code!!

LINUX started...
ADM5120 Demo board
CPU revision is: 0001800b
Primary instruction cache 8kB, physically tagged, 2-way, linesize 16 bytes.

Calibrating delay loop... 199.47 BogoMIPS

Thats about 14,2% faster.....   cool  cool

I will have to test it with full load and monitor the temperature of the ADM5120, and if it gets too hot, then i will have to get one of those heatsinks that are selfsticking and put one on the CPU. But all in all, this MOD was fast and it worked perfectly smile  cool

I do not have to tell you that you do this on your own responsibility.....just like any Overclocking or MODing stuff!!.
If you fry your Router with this MOD.....then you are to blame, no one else is responsible for it....but you already know that, right  big_smile

I think all is sead.......happy Overclocking wink

Nothing is impossible....except that the state of your mind makes it so.
