xxbassplayerxx Posted October 2, 2012 Posted October 2, 2012 I thought these chips were hitting 7GHz+ on LN2. Is it because you were using the IGP that it didn't go any higher? Quote
Massman Posted October 2, 2012 Posted October 2, 2012 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. Quote

I thought the Physics portion of the benchmark had a pretty large effect. Guess not! Quote
Massman Posted October 3, 2012 Posted October 3, 2012 Wow... I thought the Physics portion of the benchmark had a pretty large effect. Guess not! It's a balance-thing. For the Physics score to have a large effect, you also need your GPU score to be high. Quote
froxic Posted October 3, 2012 Posted October 3, 2012 Very nice, settings will very be usefull for my next LN2 session! Btw in F3E BIOS can be CPU voltage adjusted to 2,2V ;-) Quote
sin0822 Posted October 3, 2012 Posted October 3, 2012 yea the new one has more vcore option, nice job pieter Quote

[K]vlolv Posted October 25, 2012 Posted October 25, 2012 The biggest problem is that the APU will shutdown if you use too much voltage/frequency for either the CPU or the IGP. Wondering this a new bugs like llano when used D-Sub such have a limiter or maybe basic trinity characteristic Quote
jp7 Posted December 23, 2012 Posted December 23, 2012 is there a way to disable OCP with newer BIOS? i have strange issue over 1.6V with 3dmark vantage Quote
jp7 Posted December 23, 2012 Posted December 23, 2012 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 Quote
Massman Posted December 23, 2012 Posted December 23, 2012 If the problem would be OCP, the system would just shutdown. This sounds like throttling in some way. How are the temperatures? Quote
The Stilt Posted December 24, 2012 Posted December 24, 2012 changing from 4.7GHz 1.5V to 4.7GHz 1.6V get half OPS in CPU test 1 and 2 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. Quote
der8auer Posted December 24, 2012 Posted December 24, 2012 (edited) 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 Posted December 25, 2012 Posted December 25, 2012 For high FSB clocks, you should try the 'even' memory multipliers: either DDR3-800, DDR3-1600 or DDR3-2400. Also set IDE, not AHCI. Quote
Massman Posted December 25, 2012 Posted December 25, 2012 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. Quote
der8auer Posted December 25, 2012 Posted December 25, 2012 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! Quote
Moose83 Posted December 25, 2012 Posted December 25, 2012 Now go Roman, and crush the Trinity for Germany Quote
der8auer Posted December 25, 2012 Posted December 25, 2012 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. Quote
jp7 Posted December 25, 2012 Posted December 25, 2012 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. 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 Quote
