why everybody confuse about that NB..
like cloudwan said.. just don't confused with the name -CPU-NB <- i think this part most related to ACC.. -NB |

CPU-NB at the die of the proc..
NB at mobo for PCI-e.. |

QUOTE(cloudwan @ Jun 5 2009, 02:01 PM) U forgot Baby also Ah Longnb-cpu for l3 cache control right? so athlonII dont have this feature? like 8tvt said.. if acc relate to nb-cpu, si athlonII cant use acc..like that?

QUOTE(kuntawakaw @ Jun 5 2009, 02:43 PM) also Ah Long I don't think it's just for the L3 cache control, it also includes IMC control n HT communications control between the cpu and the mobo chipset for instance.. nb-cpu for l3 cache control right? so athlonII dont have this feature? like 8tvt said.. if acc relate to nb-cpu, si athlonII cant use acc..like that? Added on June 5, 2009, 2:45 pm http://xtreview.com/addcomment-id-6155-vie...on-support.htmlfound this... now nvidia chipset latest is what a? That's why some theories like 8tvt n ventrilocks quote mention that when u oc ur cpu u need to oc ur NB so that it can keep up with the cpu speed.. Just my 2 cents ah.. |

yes it is related to RAM too..so its quite complicated thing..
 just try n error for better OC...  dunno whether this is related to ACC or not.. we shall wait the person who gonna buy athlon II.. |

it's more to direct the IMC i suppose.. just assumption..
if u got to play with the ram.. same timings, same speed what so ever.. but supplied with more or correct voltage.. we can get the sweet spot.. that's where the ACC idea came about.. it's not raise the cpu volt n speed.. but when we tweak the ACC with correct value.. there go extra boost.. could be better timing loosen/tighten in correct value for performance.. oh man.. should left it in the myths n magics.. need strong will n wisdom - lol |

In my case when i play with the ACC on my Phenom II X3 it doesn't do anything, in fact it made my rig unbootable.. It will stuck at post

y need the nb-cpu for directing the imc? is there any imprvement of it compared to the older chip that have no nb-cpu?k8? pls dont stop this conversation..i love it and im learning from it..

It will stuck at post u set the value higher then cant boot? so it depends on luck also... the theory is "with higher value, more tolerate to oc..lower value for higher efficiency" but it seems not work to u.. cud it be random like my mobo cpu configuration? |

same goes when we play with the ram timing..
IINM SB700 chip just enable/disable the ACC thingy right? on SB750 directly give certain value to control the 6 pins on the cpu... what it do.. yet to be revealed.. |

@cloudwan..
try negative value..sometimes it works backward..  wat is IMC actually? internal memory control? |

Well its like when u oc the cpu-nb, u will be accelerating the communication speed between the cpu n IMC n etc..u set the value higher then cant boot? so it depends on luck also... the theory is "with higher value, more tolerate to oc..lower value for higher efficiency" but it seems not work to u.. cud it be random like my mobo cpu configuration? Its kinda like when u use a nvidia gpu beside u oc'ing the gpu clock u could also oc the shader speed.. This in the end would help the gpu to attain a better gpu performance.. That's why as AMDathlon said that when he oc his CPU-NB, some task like compressing files etc would be faster due to the internal communication between cpu n IMC/HT/NB are faster.. Just my 2 cents ah.. |

QUOTE(ventrilocks @ Jun 5 2009, 03:26 PM) @cloudwan.. I think i already tried the + value, - value n auto.. try negative value..sometimes it works backward.. wat is IMC actually? internal memory control? Auto could boot sometimes but my 4th core would still be unusable.. It must be true what they said, that Phenom II ACC capabilities are already hardwired to the cpu.. |

QUOTE(ventrilocks @ Jun 5 2009, 03:26 PM) @cloudwan.. integrated.. ala...the same thing..dont mind about term try negative value..sometimes it works backward.. wat is IMC actually? internal memory control? so the theory of acc not actually/100% right la? depends on luck also? haish..oc need tonnes of luck berdoa boley x? @coudwan now i can see it clearly..want to argue more...but i afraid of wrong info and wrong thing to ask...  |
