I will give you a warning though. DO NOT USE ANYTHING WITH A DDR MEMORY REQUENCY OVER 250MHZ ON A WRT320N. The DDR part used on these boards has an operating ceiling of 250MHz. I have tried the 533/266 setting once or twice and the board immediately locks up. After several tries (it was hard) I finally got a hard reset to take via the WPS button on the front that Eko activated. This hard reset sends you back to the default settings hard-coded in the CFE of 354,177,88 (you can see this near the top of the CFE if you view it in a hex editor). | I will give you a warning though.

Good combinations are 500/250, 480/240 (my preferred), 453/226, 400/200, 373/186, and 354/177 (std.). These are all half-speed DDR setting with relation to the MIPS CPU. The other settings choices with similar MIPS speeds and lower than half speed DDR take a big performance hit and are not worth it. You do not have to specify the third frequency (backplane frequency), but you can if you want. Anytime you specify a frequency that is maybe not in the table (if you have a typo on your command line or something) it will upshift to the next highest frequency in the table. | Good combinations are 500/250, 480/240 (my preferred), 453/226, 400/200, 373/186, and 354/177 (std.).

BTW....yes, the Asus RT-N16 and the Netgear WNR3500L are both running by default at 480,240,120. I have viewed their CFEs and seen this as their default operating frequencies. | BTW....yes, the Asus RT-N16 and the Netgear WNR3500L are both running by default at 480,240,120.

I will give you a warning though. DO NOT USE ANYTHING WITH A DDR MEMORY REQUENCY OVER 250MHZ ON A WRT320N. The DDR part used on these boards has an operating ceiling of 250MHz. I have tried the 533/266 setting once or twice and the board immediately locks up. After several tries (it was hard) I finally got a hard reset to take via the WPS button on the front that Eko activated. This hard reset sends you back to the default settings hard-coded in the CFE of 354,177,88 (you can see this near the top of the CFE if you view it in a hex editor).
Good combinations are 500/250, 480/240 (my preferred), 453/226, 400/200, 373/186, and 354/177 (std.). These are all half-speed DDR setting with relation to the MIPS CPU. The other settings choices with similar MIPS speeds and lower than half speed DDR take a big performance hit and are not worth it. You do not have to specify the third frequency (backplane frequency), but you can if you want. Anytime you specify a frequency that is maybe not in the table (if you have a typo on your command line or something) it will upshift to the next highest frequency in the table.
BTW....yes, the Asus RT-N16 and the Netgear WNR3500L are both running by default at 480,240,120. I have viewed their CFEs and seen this as their default operating frequencies.
