Voltage or Heat

Recommended Posts

What kills your CPU? Voltage or Heat. In OCing my 3200+ Newcastle this remains my biggest concern. I know that the least amount of voltage to acomplish a stable OC

is the way to go. but how much is to much should my biggest concern be temps alone or even with good temps should voltage still be a major factor.

Voltage seems to be the bigger killer. I think I've read in these forums of one person who was regularly putting 1.7V through his Winchesters and had blown three or four of them. Not 100% sure if voltage was the cause but it seems likely. For some reason I can get an extra 100MHz or more out of my Venice by dropping the voltage from 1.62 to 1.47. Clawhammers seem to be more tolerant of higher voltages though.

I agree voltage is the primary killer. I droped my vcore from 1.66v to 1.45v. I could run 2.52GHz at higher vcore, but I am feeling more comfortable at 2.3GHz with it relative lower vcore. Reducing vcore also resulting a cooler cpu temperature.

I'm just not sure what would be considered acceptable voltage and temps for my

CPU. Current settings are

CPU VID CONTROL 1.350V

CPU VID SPECIAL 123%

 

At idle voltage reads 1.63 to 1.64V @ 33 deg.C.

durring prime 95 test it will jump as high as 7.1V @ 47 deg. C. These voltage settings will pass OCCT stability test and I can run all sorts of benchmarking programs with know problem BUT in order to pass a prime 95 8 hour test I have to raise voltage a bit and then temps are peaking at 51 deg.C. I'm new enough to this that I dont know if there are ways to get more with less voltage. I accept the risk's involved in OC'ing. But there know need for me to burn something up for the sake of 1 to 2 MHz.

That's very high, I wouldn't run that 24/7. 1.65V is the highest I'd do on air period, with 1.6V being 24/7.

 

@Geeman: jesus h. christ what vCore did you put through that, like 2V? :eek:

between 1.9 & 2v

was trying for 1.9 but think i did the wrong % thing

i was trying to get my chip to 3ghz

With a 2.48GHz. OC

multi x11

htt 225MHz.

core speed 2475.0MHz.

CPU VID CONTROL 1.450V

CPU VID SPECIAL 110%

Idle temp 35deg.C around 45deg.C durring prime95 in place large FFT's

 

figuring voltages is this right 1.450V x 110% = 1.595V ??

That looks like a good spot for your voltage as you have it now.

2.5GHz. needs just a touch more voltage just have to play with voltage settings so I get just whats needed for stable. Be happier when it gets hotter around here so I can fire up household AC.

 

is this right way to figure voltage 1.450V x 110% = 1.595V
