Hi found this on a blog and tried it out.
http://aspiregemstone.blogspot.co.uk/20 … r4300.html

It works grate on my wdr3600 even tho it says it's for the 4300 they are the same bootloader.

I am not noticing more heat from my router.
I wanted to try this be for but could never find any u-boot files to flash.
If any one builds any u-boot files with better clocks can you shair pleas.

I think you can find them here

Thanks alphasparc

I have wanted to do this for ages but as I cant build the u-boot files i have had to wate to find some on the interwebs. Now i am a happy camper lol

Do you have any experience with overclocking routers? pleas share.

you can hexedit your own u-boot : http://forum.ixbt.com/post.cgi?id=attac … 4924:1.png

CPU_PLL_DATA: 4240       = 720 MHz
DDR_PLL_DATA: 4168       = 450 MHz

My Router WDR4300 goes up to 730MHZ stable.
You need to test for stability using torrents and wifi copy and usb copy all at the same time..
If it does not crash then it passes for that clock value.
Different boards, different chips different limits. It is really lottery LOL.

diff the uboots to find the offset bits which toggles the clock value.

So i have downloaded the u-boot file for 680 cpu 450 ddr and 225ahd going to give it a shot later. Will let you no how it gos. By the way what dus AHB stand for and what is ref 40.00

I think that the AHB is an internal bus within the SoC that connects the CPU core to the wifi etc sections.  Ref is the frequency of the quartz crystal on the board that all the other frequencies are derived from by PLLs.

Putting heatsinks on the SoC and RAMs would be a good idea for overclocking.  The wiki pictures of the inside of the unit show no heatsinks on the chips (but maybe it did have them and they were removed to see the chip numbers.)

There is no heatsink originally it is a very cool router.

Hi at what point wood you think about puting on a heatsink?

I put it on because I have a few lying around doing nothing.
If you need the performance you can try the firmware I maintain with the performance patches.
I tested it with my overclock wdr4300@730MHZ NAT can achieve 530Mbps on jperf.

Ok cool thanks alphasparc

Hae alphasparc have you ever played around with Gargoyle? It's what I run. I love it because
it works so well with the screen reader I use. The blocking of websites and Restriction Rules are grate to! Lets me keep my little shit kids off the net at night lol

Can it be built with the same optimized for performance, like your openwrt build?

nice lets see how this goes!

Is there any point over clocking ddr or AHB? If so does any one have any u-boots?
