phenom ii x b65

post #1 of 9
Thread Starter 
i have unlocked my cpu and from a phenom ii x2 565 to a ii x4 b65 and was wondering what unleashed mode means as my cpu voltage is set to auto and in cpu-z it is 1.408voltase and was wondering if that was safe also have a 100mhz overclock andthe cpu voltage did not increase when i set the voltage myself to say 1.38 i get a bsod on startup of any cpu intesive program

you should set the vcore manually to about 1.42 volts on the vcore and see how your cpu reacts.

thats exactly what i mean. continue having the extra 2 cores unlocked and manually set the vcore to 1.42 volts in the bios. theres a reason amd locked the 2 extra cores.....as they couldnt guarantee that they were indeed stable. its the same with the 960t zosma quad core unlocking to a hexcore. sometimes they do unlock and sometimes they dont. in all cases though in order to get it stabilized you will have to up the voltages going to the chip in order to see if it works properly. the fact that your pc gave you a BSOD, though seems to work when not being used in a cpu intensive manner tells me the other 2 cores might stabilize with a voltage jump. so go ahead and try to get the voltage to the cpu up to at least 1.40. you might have to give it 1.42. or you might even have to jump it to 1.45 to get it to stabilize. there is not guaranteed unlock with a chip that has locked cores and all the unlocks ive ever seen or read about always involve a vcore jump as you cant get something for nothing. if a voltage jump and then a cpu intensive task doesnt result in a bsod then the other cores are ok....but remember you will have to play with voltages. I probably wouldnt mess with overclocking if your chip takes 1.45 vcore to stabilize the other 2 cores as that only leaves you with another .1 of wiggle room for that phenom 2 dual core. as far as i know the voltage wall for all phenom 2 line processors is 1.55. anything more then that and you can blow the chip up.

yeah my chip is stable at 1.408v and i was wondering if that was ok as it's stable at this and i have had it to 4ghz with no voltage increase, just wanted to know if my motherboard set a good voltage or not as i wasn't sure of the max volts but i do now thanks for the help.
ps my chip idles at 30 degress celcius and maxes at 50-55 which is in my mind quite good for 3.5ghz quad core

if it stabilizes at 1.408 on the vcore at stock speed on your asus mobo then your in good shape. feel free to try and overclock a bit since its a black edition with an unlocked multiplier. you probably will have to play with voltages to the vcore to get a stable overclock as an unlocked quad core though.

Your power draw will increase to 125W TDP.  This is a problem because your motherboard is not rated for that.  You will not get reliable operation and you may lose more performance than you gain.  You need a new motherboard with a quality 4+1 phase VRM system with cooling to handle your processor unlocked properly.  Until then, keep it at 2 cores.

or.. run with the 4 cores and reduse you vCore and multi to near 2.8ghz.
