Overclocking AMD Athlon 64 X2 6400

hi,
I have a problem. And although I have tried my CPU overclock. However, I do not have 3300 MHz also.AMD Athlon 64 X2 6400 + (Zalman CNPS 9700 LED)
Foxconn A7DA-S Socket AM2 + Aeneon 4x1GB DDR2 800 RAM
XFX Geforce 8800 GTX "XXX" Edition (Thermalright HR-03 +)
BeQuiet Straight Power 500W Dual Rail ,3 disks ,3 fan (Enermax Twister Everest 92mm)
i Have already raised voltage by 70 mV. The RAM voltage was increased by 50 mV still propagated even though he ran with 400 MHz. I've overclocked via the FSB, as the multi already stands at 16 and I no longer war. So I have the FSB clock to 250 MHz and have the multi-CPU and the 13.5-HTT multi to 4 so that the HTT continues at 1000 MHz remains otherwise not boot times possible. RAM as I have said to LIMIT 400 MHz, meaning that he should not go higher. On Windows, I do something else appears. There will be a clock of 482.2 MHz specify. Can not and should actually not be. Is this already the problem? Well, increase tensions brought nothing. With the current clock of 3375 MHz while it is running stable but I am a little disappointed.
The Temps are now at last about 56 °, ie a little goes. I would max. 60 °, but even if you now say that I like because it can be the same, I will try it at least once. Perhaps soon a better CPU cooler into the case.

This is normal for K8 Athlons, since others can not get out more. CPU is just tight.

First, I would not try to make all at the same time to turn ...
Just let the multi where it is and slowly raise the fsb to ... 70mv? with how much volt it is your cpu now? I need 1.488 v for 3.4 GHz 15x 230 ... 250MHz are in any case too much ... and always on the eighth clock ram ... are with me at 485mhz set 400 does not every ram ...

when Athlons can you clock the RAM at DDR2 800 easy to calculate
simple CPU clock divided by the divisor (multi split 2 (Multi on the next straight up ie 13.5 = 14) ,with you would be 250 FSB x 13.5 = 3375MHz: 7 = 482MHz and I had the Aeneon schonmal the Rams also have a maximum at 2.0 volts at 450MHz FSB and managed by the CPU was at my 5600 + and +0.5 V, also at 230 final.
Trying times 220x16 = 3520MHz and 440MHz Ram would then this could be enough voltage to operate

Hardly, if you have the final clock speed (in the range 3.0 to 3.3 GHz) mean. As was 2.7 and not 3.2 GHz starts, it can of course relatively more over clock as the 6400 +, but oh well, I am sure you understand.
