[Solved] It takes too high voltage to get my overclocked unlocked 960T stable.

Hi there.
I am using unlocked 960T with MSI 990FXA-GD65 with Silver Arrow cooler.
I recently found that it takes very high voltage to make my CPU stable, compared to other Thuban users average at 4.xGhz@1.4xv
If the ambient temp was around 20C something, 1.44v@3.9ghz was stable enough.
In recent days the ambient temp was around 27-29C, I have to increase the voltage to 1.5v or 1.52v to get my CPU stable.
I also found that my board LLC'd my CPU to 1.7v and there's no options to turn LLC off.
The max CPU temp is 63C at 3.9ghz@1.52v while LinX burning.
I am worried about the voltage and considering to lower it along the speed.
Will such voltage damages my mobo and CPU if it is for long-term use?
I am not often full load my CPU as I just play games.

I really don't know why my CPU requires such high voltage to get stable.
Maybe I am just unlucky? Or I have got a bad mobo? Any ideas?

Any unlocked 960T users? What is your speed and voltage and mobo?
And please also tell me your ambient temp. Thanks.

you do know you have a NB voltage and a CPU/NB voltage what is your cpu/nb voltage setting?

NB is 2600mhz@1.25v and it seems doesn't matter to my CPU stability.
CPU/NB is default, I didn't touch the bus speed.
And oh crap, I just found that HT speed is too high that 2600mhz.

up your cpu/nb to 1.3 lower vore to 1.45 ,,the cpu/nb is part of your cpu and not the mobo the nb voltage is part of your mobo,,so by trying to supply all your overclock voltage to 1 side of the cpu your getting high cpu temps

lower HT to 2000 + or - 100

thanks for your help

good deal

One of the unlocked cores could be bad, maybe producing more heat/ requiring more voltage then the others? Try disabling one of the unlocked cores, then if that doesn't fix it, try the other one too. Could always just be the way you overclocked, and you need to adjust a few things, like what was said above.

-Edit- One way or another, the single core disabled would reduce heat, so instead of that actually, just try to check all of the individual core temps, and see if one is far higher than the others, or if you can check individual voltages, that might be it too

Hi there again,
I adjusted HT to 2000mhz and CPU/NB to 1.2955v
Also reduced CPU core to 1.45v
Still unstable at LinX frown.gif
So I have to adjust it again to 1.52v in order to keep CPU stable.

I know it's my bad luck.

Will such voltage damages my mobo and CPU for long-term use?
I have a good CPU cooler that my max CPU temp under uber full load is 61-65C

what mobo do you have?
