QUOTE(Thrust @ Mar 17 2012, 11:10 AM) Looks like Winrar does scale well with higher Northbridge speed. However, I found that my 990FX chipset has a freaking hot Northbridge. It could hit 80+C under load. northbridge on chip is not the same as the northbridge on the board  on chip is normally refered to as the mem controller |

QUOTE(lengchai86 @ Mar 25 2012, 12:07 PM) more than 10 times oredy check, set manually enable all core or set auto, iirc ACC dont exists anymore since 8-series boards every time boot into windows, still show only 2 cores enable... i cannot find ACC (Advance Clock Calibration) setting in the bios. i taught this board is quite good, expensive summore compare to my asus M4A 870TD/USB3 but this MSI 990FXA GD65 has a very good bios, 8+2 power phase. i love this features currently use old bios, V19.6 v19.6 seems to be the latest bios already, it probably did not unlock it try lowering your clock speed, maybe the other 2 cores unstable @ 3.9G so the board didnt unlock it |

QUOTE(lengchai86 @ Mar 25 2012, 01:06 PM) done reset bios. cannot find the reset cmos button at first, lol. very small button at the back . did you lock/limit the cores in msconfig or something? after reset cmos, still, only 2 cores enable. at bios, it shows all 4 cores enable. but the vcore suddenly drop until 1.26V++, before this 1.37v all the time at stock clock » Click to show Spoiler - click again to hide... «  bios unlock or not doesnt matter since it is already natively a quadcore... |

the problem now I think boils down to:
1) your proc 2) ram chips not playing nice with your proc btw, dont get a new proc just for that OC comp, you might as well just save money and see how PD will perform when it comes out This post has been edited by dafreak: Mar 31 2012, 10:26 AM |

QUOTE(makaroni @ May 3 2012, 11:05 PM) hi all sifu, wanna ask something, between 1333 & 1600 ram, the performance is close or 1600 is far better performance from 1333 ram? if you are not running benchmarks 1333 is enough i just bought corsair vengeance 1333Mhz 8GB & now im thinking why i just didnt buy corsair vengeance 1600Mhz.. you wont notice any difference between 1333 and 1600 in real life applications anyway....

QUOTE(makaroni @ May 3 2012, 11:30 PM) ok thanks for the info btw before this i only use 2GB kingston value ram which is give me super duper lagging when i run photoshop CS5 with other program run, after i upgrade, i really feel the big different in performance.. 10 gb vs 2gb sure got difference la...lol no more lagging now, all application run very smooth & fast btw my pc is now is 10GB ram (8GB + 2GB)  nothing to do with the ram speed...just quantity.. 4gb is normally enough for normal users, those that run CS5 or video encoding normally will go for more |
