how much voltage is too much?

Hey guys, I got some stability (so far) at 2.65ghz on my venice 3200. To achieve this I am busting out 1.6-1.63 volts. Is this dangerous? My temps go from about 29-30 idle, and 36-? during gaming/full load. What's the best way to determine full load temp and what is safe? SO yeah, just wondering if I'll be alright running 1.6ish volts on stock air with these temps.. much thanks!

first, you need to be using prime95 to stress test. also, it depends on how often you upgrade your cpu. if you do it every one or two years, 1.6+ volts will be fine, but if you dont upgrade often, dont give it more than a ten percent increase (1.55v). if you need to give it that many volts for only 2.65, you must have gotten a pretty bad oc chip.
 
Those temps look unrealistically low? I wouldn't trust those readings, at those speeds and voltages it should be more like 38-42c idle and 50-56c load with air cooling, unless your rig is in a meat locker or your in Siberia🙂.

Check your load temps after several hours of Prime large files, Or OCCT. There is another program that produces more heat, but I can't remember the name of it😱
Duvie is always recommending it for finding max load temps

yes I may have gotten a poor oc'ing chip 🙁

want to trade cpu's, I'll throw in 20 bucks 😀
 
My 3200+ Venice is overclocked to 2.75ghz (275*10) with my voltage set to 1.55 and my 100% load temps are 42C. I believe my idle temps are like 30-31C or something but I have pretty good air cooling.
 
Try not to exceed 1.5Vcore for maximum CPU life. Also make sure that Prime95 (max heat mode) does not push your CPU temp above 56C.
 
I am sitting in the exact situation. I am running 1.63V at 2650mhz on my board. Using 9x295. My temperatures are: 30C Idle 55C Load. Which is still ok as long as temperatures are under 60C you won't have a problem.

I was almost wondering if there is a situation where you could be giving too much power to the cpu and making it less stable. but I doubt that.
 
You're not exceeding 55C, but you're still pumping quite a bit of Vcore across the CPU. This will degrade the life of the chip. I would back off to about 1.575V-1.600V max. Your peak CPU temp will drop by about 2C. Suspect CPU clock speed will be 2.55GHz, plus or minus 50MHz.
 
Don't trust your mobo heat readings as actual temps. It just should heat up more than 15c or so under load. My venice only does 2.4, so I don't think that you are doing too bad 😉

Even if he did keep his current voltage and degrade the life of the chip. A chip at stock voltage lasts what..10 years, so he will get maybe 3-5 years out of his chip by having his current upped voltage, right? Most people will upgrade or build a new system in a few years anyways, right? See where I'm going with this? 🙂

Agree! I want your 2.75Mhz at 1.5V speed Joe!!
 
Hehe. I had to get a bigger PSU than the crap 430W that I got before. Even at 2.75ghz (275*10) overclock speed, my PSU didn't like it when I tried to play a game. My memory running at 181.5mhz 1T at 2-2-2-7 timings with 2.9vdimm as well. Before I attempted to play a game, I ran prime95 and memtest86 for a total of atleast 24 hours straight with no problems. It wasn't until I either tried to play a game or run 3dmark05 that my pc doesn't freeze, it doesn't lock up, it doesn't give me BSOD's, but it just SHUTS OFF automatically. LOL. The strangest thing. Come to find out my PSU isn't giving all my components enough juice when I perform this nice OC.

New PSU is a Rosewill 550W with 35A on the 12v rail. 🙂 Should arrive today via fedex.
