Computer Automatically shuts off!

Hi Guys

I have a ASROCK N68C-S UCC and im trying to overclock my phenom II X6 1045T on it. Yes I know it isnt a flashy mobo, but i cant really afford to get a new one at the moment. My problem is when i try to overclock it to 3.0Ghz (FSB to 223, Manual voltage to 1.350, Ram lowered to 1223Mhz, Turbo core, Cool and quiet disabled CPU Active Core Control disabled, AMD IO C-State Support disabled, NB Frequency x9 1950) and run prime95 my computer shuts off automatically, 5 seconds into the test.

Max temp (according to HWmonitor= 33 degrees)

Can anyone please help me?
 
Have you tried to use OC Tuner? Once you've figured out the best settings with OC Tuner, then continue to use OC Tuner or make your changes permanent in the BIOS.
 
ASRock has their own overclocking utility, OC Tuner. You should have it on your motherboard driver CD, or you can get it here.

I can't help you with that board, sorry, but I can say my 1045T on an Asus M5A97 is running @ 3.7GHz (272x13.5), ACC and CnQ enabled, Turbo Off (I think...). Vcore maxes out @ 1.416V with Prime95.

Ok thanks, your cpu-z look very diffrent from mine though. Here i tried to overclock to 3.3Ghz and it shut off with prime. I wonder, my max mobo limit is 95W and the 1045T is 93, is that a factor?

Your HT Link is way out of whack. It should easily be able to handle 2400 MHz or more, so leave it at default and see if that helps.

As for 95W TDP, It should be able to handle at least a little overclock, so that shouldn't be a factor.

I also experienced a kind of problem on PC ?

what is the possible solution for this issue?


thank you 🙂
 
Previously, someone told me this, does it make sense to you???

"What I have found out is that your motherboard is a hybrid motherboard. It combines DDR2 and DDR3 capability. The big limitation is that it has an AM2 (as opposed to AM2+/AM3) chipset. That means your HT Link frequency should not be allowed to exceed 1000 mhz and it also suggests you need to limit the CPU/NB frequency (to 2000 mhz, I would say) to prevent too large a disparity between the two which can cause instability. So, cut your CPU/NB back from 2256.6 to 2000 or slightly less (lower the multiplier). See if that helps."
 
The hybrid boards were tricky to OC at times; because using an AM2+ in an AM2 board lowers the HT down - you can tryi using the OC profiler that is in most Asrock boards to increase the OC

With is shutting down could possibly be drawing too much power and the board can't handle it so it shuts down.....but that is a guess

Does it happen only with the 3GHz OC? Is that the threshold? Meaning does it not happen with a 2.95GHz OC or 2.9 or 2.8? Only when you get to 3.0GHz it does this?

My first suspect for you would be your PSU. If it isn't capable of supplying the necessary amps at the necessary volts then the hardware can't help but to simply shut off as if you pulled the power plug out of the wall yourself.

+1 This would be my first thought as well.

Good point, but I would think the motherboard would automatically limit the link speed and can handle some overclocking anyway. Leave the multiplier at default.
 
Ok thanks guys for the responses. I have a Omega 750W psu, it has 33A on the +12V.
Also no it happens at most 2.96 as well. However when i actually tried a game (Flight Simulator X) at 3.2Ghz it ran fine for 1/2, till i need to go to school, so im not sure if prime 95 is just too much for my mobo to handle.

Just seconds in and my temps read near the top. I mean it might not be temps, but given that he can game for a while without issues, I just find it suspect.

Gaming doesn't always stress the CPU, though, and it took Prime95 ~90 seconds to drive my temps to near max.
 
How's your cooling?

I'd like to know how the OP's compares.

Honestly, just trying to rule out the obvious.
