hello
 
i'm french and i have a problem
 
i have bios A72 on a p55 classified 200 and a 655k
 
in the bios i have 160 bclk and multiplier at 27 i think the frequency is realy at 4300 mhz but in windows cpuz and e-leet say the multiplier is 24 !
 
i don't now why ??
 
please help me !
 
ps : sorry for my english

@ [link=showprofile.aspx?memid=586761]dozer3000[/link] : thanks
 
i desabled k-boost abd turbo seeting
 
all the cpu option is desabled ( ht and activ core are ctive ) c-states and turbo mode desabled !
on xp and seven 64 bit the ratio cpu stay at 24 !
 
i am going to reflash the bios !

ok i testing this evening .
 
many thanks

up

sorry for the Thread bumbing
 
no i don't have h50 !! i have a big cooper bucket !
 
i know the classified is the best motherboard but for a screen for example i can't have my good frequency on cpuz because the ratio go down at 9 !
 
i know overclocking on p55 ! and the bsod is just for say : i think in the bios the cpu ratio is realy at 29 but on windows he stay at 24 !
 
so i test this evening with  the CPU core ratio offset to 0,0,0,0
 
thanks ans have a good day !

875K in action just love..
 

 
Thanks,

From my testing

1. Set ram to target memory frequency  my ram is  Perfect Storm so 2133 MHZ  8-8-8-24 (2:10)

1. Boot up CPU  V.Core [1.32500v] but I know this is to low to support the 4.2MHZ oc Eventual CPU V.Core [ 1.32500v]   “        so I se the following; 1.38750 and 1.41875
2. [ With V.Droop]
3. Boot up CPU VTT   [ Auto] again look  out the voltages could be very high

Eventual CPU VTT  [Auto] but my setting did not boot up so I added my voltages 1.40 and 1.42 Yes  booted up I have created a list of voltages from 4.20 -5.0 MHZ  up to 4.8 has worked for me based on my 870 chip and my voltage noted
4.6’s 1.42-1.47, 4.7’s 1.48-1.54, 4.8’s 1.55-1.58, 4.9’s 1.58-1.62, 5.0’s 1.64-1.67
PCH 122’s,CPU PLL 190’s, CPU PWM 1189

1. 5.      Lock in Dimm Voltages mine are 1.64
2. 6.      CPU Multiplier 9-60  wow
3. 7.      Not sure here CPU Frequency 2133 MHZ for ram lock in our ram setting
4. 8.      CPU Multiplier 20= 4.266, 21=4.480,22=4.693,24=5.120

 
 
 



Thanks,

Thanks mack!!!
I will downgrade to A71 and try to use C1E..
this is always off.. because it wont work properly...
but I'll try your settings..
Thanks a lot.

.. and... I need a chiller :D 
how about your water temps?

Yes.. also with A71
Advanced CPU Settings 
Ratio Status Unlocked Min 09 Max Unlimited 
Ratio Actual Value : 22 
 
So set the Ratio Status to your "min" f.E. = "max"

it's blowing into the case?? 
What's about your water temps?

The Heatkiller 3.0 is the best.. in all european benches / tests, the heatkiller is at at the top of the class.  
Only the Aquacomputer Kyros (new) is in some tests a little bit better. 
23°Celsius or fahrenheit? :D
 
And .. after 2 hours of load?
 
BTW: i think, we are not right here in this thread ;)

i am having trouble flashing my p55sli.  i ran the program but never got anything that asked me to press y.  do have to make a boot disk?  how do i figure out what bios i have installed?
 
 

you actually took the time to respond with that?

Good luck my friend
 
Thanks,
Mack4033

You do not have to run turbo boost . It's safe to disable it in the bios . I also prefer higher clocks but instead of using speedstep I disable that and use cstate . It works best for me .
