Looks almost realistic that you have 1000 MHz on your cpu and 600 MHz on ram if i compare the values with AR9344@750MHz.
But probably your system timer isn´t accurate and then the benchmarks will be not true.
@juppin what will happen if your CPU clock runs @ 500 MHz but the kernel thinks that it runs @ 1000 MHz (in case of ath79/mips, time base is based on CPU ticking)? Small hint: all results from tests which are time-based are wrong.

Yes, that was also my conclusion at the same moment. 
We could only be sure if one measure with a oscilloscope...
A benchmark that executes always the same code and a time measure with putty between start and end print could be much better than this benchmarks that rely on systick timer...
or by crypto by ssh the speed on a remote computer

@psyborg I confirmed your CPU clock with a scope. There is also MikroTik hEX lite (RB750r2, QCA9533 based) which runs by default with CPU @ 850 MHz and allows setting up to 1000 MHz.

u-boot was actually capable of starting at 1100MHz, but would not boot firmware. maybe the clock drift issue described in Archer C7 V2.0 Overclock thread is the cause of this.. i've also tried 1200MHz and u-boot hangs there.
I was able to run 1 GHz only on one from two QCA9531 based devices I tried (didn't have more time).
Ok. 1050MHz is max at which device is stable without heatsinks or fans. RAM max at 625MHz (might do better if i manage to replace it for 64M one). Do you know if there is a way to set SPI clock independently on AHB clock? I found that device won't boot at 40MHz but boots fine at 37.5MHz (AHB300/8) but i want to use AHB @ 200. Maybe derive it from CPU clock?
Derive it from CPU/5, at 1050MHz you'll get 210MHz AHB. Maybe BREED is an option for quick changes, then settle with optimal clocks from u-boot.
where could i find safe clocks values for tplink wdr4300?
my understanding if i use values to high i will brick router.
i looked at pepe2k setclk method but it says wdr4300 not supported by setclk
The doc says, but this is outdated...
On my WDR4300 i have 750 MHz.
The set clock with setclk is applied only if the reset button isn't pressed... So if you set a to high clock, start with reset button pressed, your router does not use the stored clock settings and use 400 for cpu.
At the moment i dont know the safe default values for ddr, ahb and spi...

Thanks for sharing this helpful information about overclocking router devices. Maybe I should also try these tips and see if it will improve the performance of my device.
Is there way to overclock older Broadcom bcm47xx routers? Such as Asus RT-N16?
In DD-WRT there was command nvram set clkfreq
Routers with 9344 cannot be oveclocked with pepe2k uboot, just found setclk is missing, you probably overclocked WDR4300 with some other uboot
actually they can be overclocked by editing the uboot with a hex editor...
that is whole point i do not want hex editor, he said can be oc with pepe uboot but cant for routers with AR9344 because setclk is missing
