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

Belgium Massman says:

Yes.

 

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!

cool report man

It's a balance-thing. For the Physics score to have a large effect, you also need your GPU score to be high.

Nice report pieter!

Czech Republic froxic says:

Very nice, settings will very be usefull for my next LN2 session! Btw in F3E BIOS can be CPU voltage adjusted to 2,2V ;-)

United States sin0822 says:

yea the new one has more vcore option, nice job pieter

Russian Federation DKZ says:

AHCI MODE? OR IDE MODE

Belgium Massman says:

Ide

Wondering this a new bugs like llano when used D-Sub such have a limiter or maybe basic trinity characteristic

San Marino jp7 says:

is there a way to disable OCP with newer BIOS? i have strange issue over 1.6V with 3dmark vantage

Belgium Massman says:

What is the strange issue?

San Marino jp7 says:

What is the strange issue?

 

changing from 4.7GHz 1.5V to 4.7GHz 1.6V get half OPS in CPU test 1 and 2

Belgium Massman says:

If the problem would be OCP, the system would just shutdown. This sounds like throttling in some way. How are the temperatures?

Or air cooling?

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.

Germany der8auer says:

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.

Belgium Massman says:

For high FSB clocks, you should try the 'even' memory multipliers: either DDR3-800, DDR3-1600 or DDR3-2400. Also set IDE, not AHCI.

Germany der8auer says:

Thanks PJ. Gonna test it now.

Belgium Massman says:

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.

Germany der8auer says:

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!

Now go Roman, and crush the Trinity for Germany :D:P

Germany der8auer says:

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.

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 :(
