So...you have an AC1450...but it shows as an R6300v2.

The FCC ID is the same for these two models...but they have different board_id numbers in the nvram settings. Somewhere along the line...your board_id got set to an R6300v2.
Good point; and... Hey Redhawk!

@macexperts You can also check the board_id (and all the other defaults) in mtd0, similarly as I mentioned above. Though a full reset should have fixed it... I have seen where some types of resets don't actually reset everything. Assuming this isn't a DD bug...

Overclocking in the webUI was disabled a while ago... where you been? Too many people bricking their routers....

Using OpenWRT mostly Razz Lots of other various projects going on though.

But I did say I thought BS may have done so. Wink Nothing a reset can't fix, if one knows what they're doing. Cool

[...] PS I only see 800/600 in the clock
Ok cool Smile BS may have restricted overclocking; or this model doesn't support it (the R6300v1 does not; but it's a totally different SoC). Try setting it manually*; backup your nvram in case you have to reset.

Check your `cat /proc/cpuinfo` output (or `dmesg|grep -i hz) before and after (if there's no frequency listed, go by the 'bogomips' field). Then check `nvram get clkfreq` for reference**. In telnet/ssh:
    nvram set clkfreq=1000,666
    nvram set overclocking=1000
    nvram commit && reboot
The 'overclocking' parameter is to prevent DD from resetting 'clkfreq'. If it can overclock (stably, of course), that should almost proportionally increase CPU-bottlenecked NAT speed (25% for those playing at home).
* To compare, my EA6900's OEM nvram (& CFE) had clkfreq=800,533 while the third-party Xwrt CFE used 800,666. The datasheet for the memory showed it rated for a minimum of "667", and I've been running it (and now a 2nd) at 1000,666 for years. I reset the heatsink (from thermal pad to good compound) and drilled some holes in the top of the case to drop the temps down. Not necessary, but it will impress your friends and influence neighbors. Cool
** To check the CFE default: `strings /dev/mtd0|grep clk`


I dusted off the old EA6900 which was sitting in the holiday home but my overclocking utility which I reinstated again (see picture) has 400, 533, 667, 800 as memory frequency

Should the default not be 667?

Furthermore The temps are over 70 Celsius is there a thread to open the router and reseat the heatsink?

Broadcom 1/3 and 2/3 speeds increment by 33's and 66's.
E.g.: https://svn.dd-wrt.com/browser/src/linux/universal/linux-4.4/brcm/arm/shared/hndarm_ca9.c#L92

I imagine 667 is just a display value, and not from the actual pll table. Are you using an Xwrt CFE? Check your `strings /dev/mtd0|grep clkfreq`. Mine was 800,666, while the OEM was 800,533. Does your resultant clkfreq show '800,667'? And does dmesg report the speed? (out of town on vacation atm, so can't check)

I didn't post one for it, but I used a plastic separator tool to (carefully) open the lid; Linksys/Belkin/D-link cases are the worst. :-/ The heatsink has 3 screws I think, so my usual straight-edge razor blade to remove the old material, de-wax/grease solvent (I use PPG DX330; high-purity alcohol is prob ok), and little 330/400 then 600 grit wet-sanding if the surface is rough and/or un-flat. The case top has a grid structure inside, making hole drilling pretty easy (then a countersink to clean them up). I made 20 holes total, about 1/4"-5/16" or so. Dropped the steady-state temp quite a bit. Smile

If you're going to go that far, just add a couple of cooling fans to pull air up through the case Cool

Thanks @jwh7 that was the list I was looking for, I have my specs from the JEDEC listing, the actual transfer rate is 666 2/3 so you have SDRAM 667

But Broadcom apparently lists it just as 666 Smile
(the devil is in the details, pun intended)

Yes I use the Xwrt CFE with that it runs fine and I have clkfreq=800,666

Will have to think about opening and resetting the heat sink, just having a fan blowing is perhaps the easier solution

Eff that noise (pun very much intended)! Razz

Better late than never?
EA6900 (and other EA's...) simple cooling mod
