Prime95 and your OC Results

[keichan82]

Hi. Just want to compare some overclocking results along with the level of Prime that is used to test it.
Anyone know what level of testing is REALLY stable?

The 3 level listed in Prime95 are:
Option 1: Small FFTs (maximum FPU stress, data fits in L2 cache, RAM not tested much)
Option 2: In-place large FFTs (Maximum heat, power consumption, some RAM tested)
Option 3: Blend (tests some of everything, lots of RAM tested)


Please Post your spec so we can compare. Thanks.

Prime95 Level: Custom - Min FFT 2048 / Max FFT 4096 ; sometimes w/ FFT's in place...sometimes w/o

I use the custom setting. It seems to detect instabilities much quicker...usually within a minute or two. I use FFT's in place when trying to only stress the CPU. Sometimes I'll use the blend test for the ram, but usually ram instabilites show up without much effort.

although I frequently just run it at 200*13, as that only requires 2.0V
yes, my system will die sometime. i know that this level of voltage will kill a Barton even on good water.

my system will die sometime. i know that this level of voltage will kill a Barton even on good water.

I don't buy into this statement. As long as the associated heat can be removed, the voltage shouldn't lessen the life by such a considerable margin. In fact I would think you will be crying for a new CPU before the D-Day came. Unless someone has some info I haven't heard of, but I haven't heard of a high rate of CPU death by a properly cooled Barton running 1.95-2.0V.

Not necessary. Giving more volts to the CPU melts the gates faster (gates are what a transistor is made up of....any material science class will teach about this), no matter how quickly or efficiently you can remove the heat from the CPU.

BUT it will be long before your gates are fully melted to the extend that they wont allow passage of current. Dont wry, you are shortening the life of your CPU but you will have upgraded atleast 2 generations before that CPU dies running at that voltage 24x7.

Almost all CPUs are designed to work for atleast 10years and almost all will run for much longer period than that (personally have seen a P 133Mhz system that has been running for the last 8 years). Even if you are supplying it much more voltages, it will still run for a long long time. Note: There are always some exceptions, so dont take my words seriously.

:Q 62 hours !!!! duvie takes prime serious ..so much for bad mem controller folks (aka user error)

 

[Duvie]

I sorta forgot about it after 24 hours when I was previously going to stop...I was doing everything regardless and never shutdown or restart the system unless adding hardware or software that requires a reboot.....So I let it run, and run, and run, and run....Finally I had to stop cause I needed to install a piece of new hardware.....
