Prime95 Shutting off my Comp?

Hey guys. When I OC my comp and run prime95 it doesn't fail or anything. After 5 min or so my computer just shuts off the power. Anyone know what givess???? Is it my bios temperature setting misreading the temp and activating Asus C.O.P.? Then if so how come it doesn't occur at default clock speeds and at the same voltage of 1.775? Help!
 
Umm heat? My Asus Probe is reporting temps of 44 Max. Before the sudden shutdown occurs. I'm running Thermalright Sk-7 and Thermaltake Smartfan II at full speed.
 
a cpu can go from 44*C to 100*C in less then 1 second ~ youd never see it 😉
the other possibility is your PSU aint nearly good enough.

i am NOT an amd man so thats about as much opinion as i can give you.

yeah get out of this thread!!!

🙂 go back to your intel world!!!

anyway...

sounds like a heat issue as well... do you have it setup so your comp will shut off if temps get too hot?

You might just want to take a hike...? 😛

Is a highly respected member around here... 😉 Also has forgot more than most of us might even learn...

Besides I bought a very awesome chip from him too... 😀 (a P4 1.6a made it in to Win9X @3.06Ghz... and he is the Intel man... 😉 )


My guess is PS...?
 
hmm cpu shut off cuz of heat...only thing that might be doing this is asus's c.o.p...cpu overheating protection...but i have good heatsink and fans...meh....?????
 
FOTN ~ lower your room temp alot! open a window, open the case, anything to make it cooler.
see what happens 😉


to those that dont know ~ Shimmishim & Bartman39 are just teasing me (and each other) cause i am actually sticking my nose in a AMD thread :Q 😉 🙂 😀
 
Did you move your SK-7 as far away from the solid-plastic end of the CPU socket as possible, like I mentioned to you before? If not, make sure to do that.

Asus Probe =

Also, make sure not to plug the Smart Fan II into your motherboard for DC power, it will eventually burn out your fan header due to the extreme amperage it draws.
 
the heatsink is in place....the fan has its own molex supply from psu...and my room is freezing cold...lol temp conditions for yesterday:
Current Conditions: 0 F
Feels like: -19 F
Cold enough for you? Both of the windows in my little college room were open.
 
The heatsink is in place, yeah, but is it in the RIGHT place? I'm not sure I'm getting through to you, so we will try something dramatic and creative... 🙂

Ok, imagine you are in a locked room with a vampire and you don't want your blood sucked out! :Q What do you do?! :Q You try to get as far away as the vampire as you can, right? Now, imagine that the vampire is the solid-plastic end of the CPU socket and it wants to suck the MHz right out of your CPU, and you are the heatsink :Q You flee as far to the other end of the CPU socket as the clip will let you! :Q And miraculously, you find some garlic there, far far away from the raised, solid-plastic end of the CPU socket, and you fend off the vampire from your refuge at the far end of your clip, and you live to overclock another day. 😎

Eh? 😉
 
yes lol...i located that part and pulled as hard as i could lol in the opposite direction....well as hard as i could without ripping it out....i'm just macho like that 😉....lol yea so i think its in the right place now....well my current status is that i backed off the voltage to 1.725 and its working fine...but i don't get why grr....its not working at 1.775 that seems to be very popular....and ts not like i got a bs HSF or nothing...UGH

P.S. Lol I liked your example. Very dramatic.
 
Ok cool, I made someone laugh today 😀 Well then I don't know what to say about the power-offs, there isn't a user-adjustable shutdown temp in the BIOS, doesn't look like 😕 And your cooling is first-rate. The end of the heatsink clip with the screwdriver fitting is facing the DIMM slots, right?
 
I would assume heat man.

shit im on water and my room gets hot enough that i can crash out of prime95 with in about an hour.
when my room is cool prime will run for days.........even water doesnt help stupidly high room temps 🙁
 
Maybe I should butt out, since it looks like you have a heatsink fault and MechBgon is taking good care of you. But. maybe a list is useful, so you won't be surprised.

When running an OC to the ragged edge and Prime95 torture testing, I have gotten these crashes

The least dramatic and most common, is that Prime95 stops and issues an error. It can stop about as soon as you click the mouse, or it might take 15 minutes, an hour, or several hours. Sometimes you can monitor the temperature, and when it gets to a certain point, BINGO. When you OC to the limit, that temperature is not very high, and not at all dangerous. The switching speed of transistors goes slower as the temperature goes up, and this causes the CPU to malfunction.

Windows says it is closing down some program (Prime95) because it caused a fault.

Windows freezes, but it beeps when you press any key, although it doesn't do anything but beep.

Windows freezes and does not respond to keyboard or mouse clicks. For whatever reason mouse movement is the last to go.

XP blue screens and tells you it is doing a complete memory dump to HD, which takes several minutes.

XP blue screens and tells you it has shut down the computer to protect it. You have to push the reset or power button.

The computer black screens, dropping out of Windows and the computer spontaneously reboots, sometimes locking up before it gets far.

Last but not least, and very rare, the power shuts off.

Like I say, this is pretty normal stuff when you push to the very limit. Well, I didn't mention the final one, because it never happen to me. The power shuts off, and the computer never boots again. I think this is because I don't put 3 volts on a 1.6 volt processor and think that water cooling is going to "keep the temperature safe". The CPU does not have to get hot to get killed by voltage. It could be 300 degrees below zero. Keeping it cool does not protect it from voltage. And likewise, keeping it cool is not done to keep the CPU safe when OCing, although it does that. The CPU crashes at a lower temperature as you OC further. That is why it needs to be really cool. You can boil water on AMD CPUs and though it may not work when it is that hot, it should survive and work as it cools down. With faulty cooling though, the temperature can rise to the killing level in a few seconds.

 
Hmm thanks. But you talk about room temp. But my room temp is at the freezing point. And it shuts right down. Its clicking...its processing. Then zip....power off. And it gives me some weird keyboard dectection error when I turn it back on and I fix it by clearing Bios.

Hehe, I've played too much Mechwarrior 2/3/4/Mercs and I have a lifelong fixation with heatsinks now 😀 In fact, I ran out the door to the bus stop this week and suddenly realized I hadn't brushed my hair after getting out of the shower, so I looked in my bag and what did I find to comb my hair with...? One of these (I got two and haven't used the second one yet). 🙂 It was a little grabby, but it was better than nothing 😀

The sudden power-off just screams CPU overheat shutdown, but other things that can cause a sudden shutdown include a short circuit. I've let a vacant 3-pin fan adapter touch the case before and the system sees the short on the 12V line and shuts down right away. Maybe try running the system outside the case to eliminate some of the variables. This could be a difficult thing to troubleshoot, but you gotta start somewhere.

Nice. Blue. Too bad AMD changed their approved specs so the CPU heatsinks are all plain now. I liked the blue ones.

Actually you have a pretty good idea. Why waste money on a brush or comb when you could put that same money toward a heatsink? Whenever somebody buys a NEW(?) car, I always think to myself: "D@MN! What a computer you could get for that!" People are so wasteful, aren't they? For the price of power steering they could get a new CPU. For the price of air conditioning they could get a great computer. What goes on in these people's minds?😕

Everybody should have a few spare heatsinks, just in case. You never know. It never occured to me carry any around with me like you do. Good thinking!

Oh yeah, I don't have any problems when I keep the CPU in its operating range, just to make that clear. I wanted to warn people what CAN happen, and HAS happened when you push it just over the edge. OCing is not 100% fun. All this might happen when running prime95, and yet if you keep it to surfing the Internet it will do just fine and Windows will run for a month without a hitch.
