I'm from Roumania so please excuse my english. I recently unlocked my Phenom II 960T to 6 cores and stress tested it with Prime 95 for 3 hours and 13 minutes. I will upload 2 images for during test results and after test results. The CPU passed the stress tests but i have a few questions just to make me feel safe.
1) does the 3 hour interval stress test qualify my current setup as stabel and safe ? and can i leave it unlocked every day without any problems ?
2) I use this pc for gaming mostly, so is it better to unlock the 2 extra cores or go back and overclock the standard 4 cores. (I plan to get a gtx 670 in a week)
3) I noticed that the hardware monitor registered a max temperature of 115 C for the system chip (TMPIN0), a max temp of 78 C for the CPU (TMPIN1) and the 3'rd one i don't even know what it is for. The thing is that i monitored the temps myself during the test, and the constant max temp was 50 for the CPU and 40 for the system chip. Those high values, over 78 C, apeared just for a second, randomly (1 or 2 times ). Do i need to be worried for this in any way ??
I have AMD Cool and Quiet enabled. I didn't change anything in bios, except enabled Core Unlock.
Thank you for youre patience!!!
My Pc components :
MOBO - Gigabyte GA-990FXA-UD3
CPU - AMD Phenom II x4 960T
GPU - Asus Ati Radeon HD 3870x2
RAM - Corsair 4GB (dual channel), 1333MHz
PSU - Antec TruePower Quattro 1000W
Cooler - Thermalright HR-02 Macho
If you're just gaming then lock the cores back up, you really won't benefit from them at all,
if you chose to leave unlocked then yes, 24/7 is fine
78'c is way too high, make sure your voltage for the cpu is set as low as possible once you have locked the extra cores back up,
and I'd say your next purchase is a newer graphics card,
congratulations on a successful unlock though man
I think everything in bios is on auto, regarding voltage. I underline the fact that the 78C temp only appeared for a split second , 1 or 2 times. Could it be a error or is it a voltage spike for sure ?
Could be a spike yes, but for peace of mind I would go through the Black edition clocking guide up top, and learn how to find your 'best' voltage, you need enough to run obviously, but too much voltage ends up as waste heat, its a balancing act
I wouldn't let a mobo decide how much voltage I need, simply because it will always over-volt and up my temperatures
if you are happy with temps and performance then no need to worry, its just my opinion
I turned the voltages from auto to manuall, in bios. I still am trying to convince myself to go for overclocking the 4 default cores, instead of staying with the unlocked 6 cores. As i said i will be purchasing a gtx 670 soon and i have to watch out for bottlenecking it. The only thing keeping me is that i have never done this before and am afraid of messing it up.
One last thing i noticed, now that i was interested in voltage readings, is that -12v and +5V VCCH readings are changing all the time, and i see some wierd values that i don't think are right. I don't know what to make of this, is something wrong if the max value for the -12V hits -4,99 and the max value for +5V VCCH hits 3,66 ?? (i know that the +5V VCCH is for powering the motherboard and usb while the pc is turned off, but i always turn the PSU off, from the back button, when i shut down) . One thought was that these changes might have to do something with some power saving programs i have installed (motherboard utilities).
Voltages do fluctuate, higher quality Psu'd regulate it better/more efficiently to reduce spikes and drops,
but still you will find that it varies,
Those readings do seem off though, well out of what I'd consider a normal range, might be worth checking your connections, but the truepower series are pretty good as far as I'm aware,
I wouldn't bother flipping the switch off either unless you live in some remote blackout-ridden area, its not necessary and will run down your Cmos battery quicker
Thank you moto, you have been very helpfull. I downloaded 3 new hardware monitor programs (open hardware monitor, speedfan, pc wizard) and i noticed that the cpuid hardware monitor, wich i used the first time, is the only one registering those exagerated values. Now i am convinced that CPUID is not reading them well, or is not tottaly compatible with windows 7 64 bits.
I convinced myself that the setup is stabile and safe (otherwise it would have stoped working or shutdown if it really reached those high temperatures).
Thank you once again.
