Raising voltages problem Please help

[onemorekornkid]

Ok, I am trying to get my voltages on my 2400+m up to 1.9 volts so I can get it stable 220x11 (I am taking advice from another person who easily accomplished that) and if I get it up to 1.9 volts at any speed, while running p95, after about 5 minutes, the computer turns off and the siren alarms. What gives? I am running it at 1.875 volts right now and nothing is wrong and p95 is fine (except for it failing).

Why is the computer turning itself off?

I am thinking about just ignoring p95 altogether and just running it at 1.9 volts because I ran 3dmark05 CPU test at 1.9volts and nothing happened.


Anyone have any advice?

Seriously people. I really need this.

My first guess would be that the power supply is deasserting PWR_OK (pin 8 - usually grey - on an ATX power cable) which would be an indication from the power supply that it can't maintain the output voltage on one of the power supply wires. But when you say that sirens sound, then this wouldn't fit that explanation. Depending on the motherboard firmware, on most computers deasserting PWR_OK either reboots the computer or does a hard shut down - I've never heard of a motherboard that shut down and then triggered an alarm. You can check PWR_OK using an oscilloscope, although I don't know what you'd trigger on.

As far as Prime 95, if lowering Vcore by 250mV keeps the system from rebooting, then you are operating on the bleeding edge of failure and are likely to run back into this problem the next hot day that rolls around, or when you fire up some new game like Half-Life 2. I've heard Prime 95 is considered too stringent a test - there's another thread on here that says that it's a 'fallacy' to rely on it for stability - but it's merely a sequence of instructions that calculate values... if the CPU starts spitting out bad numbers out of Prime 95 (or reboots), then it's not running ok in my opinion and dodging the issue by blaming it on Prime 95 only opens the problem to show up again later in some other application.

The real question to ask is - if your computer starts failing doing some application what are you going to blame first: hardware or software? Personally, I only want things failing due to software. If you add the extra variable of hardware into the picture, then it takes that much longer to get the root of the problem.

I have a turbolink 420 watt psu (not the best at all, but it gets the job done) and the lack of it not being able to keep up might be the problem, however, my rails are perfectly fine.

And there are somethings I noticed that might be a root of the problem-

The only way I could get my processor up or higher than 1.875 was by this method: Simply setting it to 1.875 would make the siren go off after the bios had saved. SO I was forced to turn off the computer, unplug the psu, plug it back in, turn the psu back on, and the BIOS was forced to have that current 1.875 or higher voltage. Raising it any higher from 1.875 wouldn't make the alarm go off mind you.

IN CPU-Z and MBM5, it says that my cpu is only recieving 11.875 volts when I have the BIOS set so it recieves 1.9 volts (the BIOS says it's outputting 1.9 volts too). What do I trust?

And this problem only happened after I took the voltages and mhrz down to stock (1.8ghrz, 1.65 volts) for recording purposes. I then put it immediately back up to 2425 mhrz and 1.9 volts. Could the sudden change be too much?

I am thinking about reinstalling my BIOS and starting over, hopefully that will do something.

what is your mobo? what are your temps? what are you running for memory? as a northbridge heatsink?

reeflahing your BIOS wont help anything unless your flashing to a modded BIOS or a different one. I suppose its possible to corrupt the BIOS, Ive never done that myself, but if pulling your voltage back down fixes the problem then it is obviously not the BIOS' fault. It is a hardware failure or something is setting off the motherboards default alarms.

Have you tried bumping all of the alarms up a notch? Like the heat alarm and such?
