Overclocking Buffalo WHR-HP-G54 running Tomato

    Has anyone tried to overclock Buffalo WHR-HP-G54 running Tomato?
    If yes, at which frequencies it is running stable?
    Note that I don't want to install heatsink or do any other hardware mod.

    I have very fast connection - 40 Mbps download/upload.

    When using my full bandwidth the CPU Load is greater than 1.0, so some packets are being dropped (I get timeouts when pinging the router's IP).
    I am going to try the Tomato SpeedMod, but I guess some more raw power will help too.

    disable QoS, use WHR-G125, or OC to 240MHz, make sure you know how to use JTAG and BACKUP your bootloader+flash. Anyhow, I patch the bootloader and reflash so it'll survive a hard reset. It is also a great way to brick your router. hehe ;-)

    Yesterday I flashed the SpeedMod and there is some improvement. Speedtest gives me better results:


    But still I have some packets dropped when using my full speed. So I am still interested in overclocking. Can someone confirm that these are the right commands to overclock to 216 MHz:

    I wonder if it is possible to brick my router by overclocking to 216? I don't want more because it doesn't have heatsink and I don't want to install one. My CPU is loaded at 95-96% at full speed, so I guess even 16 MHz more will have possitive effect.

    I have read that there are different versions of WHR-HP-G54, mine has 2 different model names on different stickers on the box:
    Does anyone know if this version can be successfully overclocked and at what frequency? Thanks in advance.

    The WHR-G125 may be the fastest Tomato router you can get right now.

    With the kind of d/ AND u/l speeds your getting, to fully utilize it, you need a much higher performance router. D-Link's DGL-4500 or equivalent gaming router, I heard is quite good for a dual-band router. They have additional co-processor to deal with the stress of high speed connections. Just make sure you update to their latest firmware, and stress test it SEVERELY for 30 days or so, if it overheats, reboots, locks-up, return to store at ONCE.

    Do you use QoS in your router?

    If you do, this tip is from the speedmod author. It may help you save more CPU cycles:

    Thanks for the tip, but I don't use QoS, it is much slower with it and actually there is no need to use it. Whatever I do the pings are low, there is no congestion. QoS is good for asymmetric connections, where the upload speed is low, mine is 40 Mbps.
    I will try to overclock at 216 MHz. I hope that this will help a bit.
