Safe 3700+ Voltage

[meaz]

Hi all,

What is generally accepted as the max safe voltage for a 3700+? I've heard upto 1.55/1.6v is perfectly fine as long as the cooling surfices. Is this true? this rig runs 24/7 100% load and I'd like it to last 2/3 years without the cpu dying. Temps are under 46 load.

I was testing 2700MHz but can't even run super pi with 1.39v so I am thinking 2700 to be stable if it will be that is might require say 1.45-1.5v.

Thanks for any replies

I run my 3200 at 1.55v 24/7. As you can get 2.7 (almost) on low voltage you should be able to gwet 2.9 with around 1.5v.

Although your cooling doesnt seem to be that good, what are you using?

Thanks for your reply.

I'm running an Artic Freezer 64. I expected much better temps tbh but my case temps are high due the room temperature (case temp of 35-37c). If the CPU is idle or just doing internet stuff and msn it doesn't go above 43c and 50c is the max I've seen before the paste had bedded in it seems...now its 45/46c full load.

I am thinking my PSU is holding me back as the 12v rail can only give 17a which I've read isnt sufficient for stock A64 systems, let alone overclocked ones.

Do you know if there is a risk of my PSU blowing up if I set the vcore to more than 1.4v ? as Im sure it is the weak link as it's a generic 500w. When I get a new PSU, in a few days I will try and see what I can get to with 1.55v if the temps dont sky rocket.

Cheers,
Meaz\

Hmm ive been running my venice [email protected] with 1.6v lol, im preety sure im safe so you should be.

nice one thanks. I might try more volts later, probably not that much chance my PSU will give up, probably just won't POST or something till I reset CMOS.

It takes 1.55v to get my 3700sd prime stable at 2.8. Will boot into windows at 2.9 at the same volts but fails prime after 10mins or so. My temps are good at 2.8, idles at 28/29'c and hits 40 under heavy load (12+hours of prime 95)

i've been running my 3700+ at 1.55 for 1yr without problems (watercooled). i'm clocked at 2.95ghz and also removed the IHS from the cpu which drop the temp of my cpu from around 45C load to 36C.

oh btw... before the IHS removal i could only clock to 2.85ghz.

Just remember its all about the individual CPU you have as well. Just by upping the volts doesnt necessarily mean that you will get a higher clock.
