The board is limited to 1.80V Vcore, if I remember correctly, and I was hitting about 6.5GHz on both chips with that voltage. The biggest problem is that the APU will shutdown if you use too much voltage/frequency for either the CPU or the IGP. So, in order not to trigger the shutdown I kept the CPU at relatively low voltage and frequency.
Besides, the effect of CPU frequency is almost insignificant anyway. 1GHz additional CPU frequency equals a total of 11pts boost in 3DMark11.

Wow... I thought the Physics portion of the benchmark had a pretty large effect. Guess not!
Fyi, around 133MHz BCLK (forgot whether it's 133 or 140) the board will switch to the external PLL. So, you might want to go in small steps there. Something like
100 -> 105
105 -> 130
130 -> 145
145 -> 170
Around 170MHz -175 to be precise- was the highest the board could do with multiple CPUs. Afaik, it was related to the used clockgen (you could do a little higher fiddling with clock spectrum).
The boot-in-windows issue is 99% IDE/AHCI related.
Okay I'm realy annoyed now.. Spent 3 days to get the correct performance and to unbug the system with these crappy AMD drivers and when I just wanted to start the 2nd Lightning died out of nowhere on stock clocks.
If so it is most likely either VR_Hot (VRM) or CPU HTC activation (@ 70,0°C).
Enable "PowerMode" with TCI K2 and see if it makes any difference.
However it certainly isn´t VRM OCP.
SS cooling, is not related to temperatures, CPU\GPU under zero and VRM are not hot, after some run 22/24° ( checked with TCI K2 )
enabled PowerMode but doesn't change the situation.
it is very strange... I can't understand why there is this sort of throttling however tomorrow I am going to format and reinstall OS but I am not confident

I thought these chips were hitting 7GHz+ on LN2. Is it because you were using the IGP that it didn't go any higher?
Massman dit :
Yes.

cool report man
Massman dit :
It's a balance-thing. For the Physics score to have a large effect, you also need your GPU score to be high.
der8auer dit :
Nice report pieter!
froxic dit :
Very nice, settings will very be usefull for my next LN2 session! Btw in F3E BIOS can be CPU voltage adjusted to 2,2V ;-)
sin0822 dit :
yea the new one has more vcore option, nice job pieter

You guys should take a look at this ^^

AHCI MODE? OR IDE MODE

Ide

Wondering this a new bugs like llano when used D-Sub such have a limiter or maybe basic trinity characteristic
jp7 dit :
is there a way to disable OCP with newer BIOS? i have strange issue over 1.6V with 3dmark vantage
Massman dit :
What is the strange issue?
jp7 dit :
changing from 4.7GHz 1.5V to 4.7GHz 1.6V get half OPS in CPU test 1 and 2
Massman dit :
If the problem would be OCP, the system would just shutdown. This sounds like throttling in some way. How are the temperatures?
The Stilt dit :
Or air cooling?

I don't understand why I can boot up to 145 BCLK but just 106 into windows? And only 102 BCLK are benchstable...
Also I can not go above the 1866 memory divider. If I used 2133 or above it doesn't boot anymore.
Pretty much same settings / voltages like Pieter used in the first post.
Massman dit :
For high FSB clocks, you should try the 'even' memory multipliers: either DDR3-800, DDR3-1600 or DDR3-2400. Also set IDE, not AHCI.

Thanks PJ. Gonna test it now.

der8auer dit :
Yes it was IDE related The memory issue was due to wrong subtimings. I had to set all the subtimings manually. Now I can also use 2133 MHz divider.
I'm aiming for about 120-125 MHz BCLK for benching. According to Hicookie the board switches to the external PLL at 133 MHz like you said.
Thanks!
