Overclocking issues and questions

[TheDigitalRealm]

Okay, so after about two months of building my rig, I decided to go into CPU overclocking. I started by using CPU level up, which took my CPU up to 4.6 GHz but was extremely heavy handed on the voltage, bumping it up to 1.350v.

After much validating and booting to bios I managed to decrease the voltage to 1.240v tested under 7 hours of AIDA64. I'm unsure of how low that is, but I've heard that it's pretty good for Ivy Bridge. (I was getting an average of 70 celcius on hottest cores, 64 on coolest)

I tried going down to 1.235, and only had time for a 2 hour test. I went into playing a few hours of battlefield, and after what must have been 3-4 hours I got a STOP error and my PC restarted, so I moved the voltage back up to 1.240. Can anyone tell me what's going on? I need help!

Sounds like when you went to 1.235 you simply had an unstable overclock. My 4670k (4.5GHz 1.25V) made it through 4 hours of Prime95 before I assumed it would work. It then promptly started crashing while gaming. Your temps are fine and your voltage seems fine so there shouldn't be any problem (unless I'm missing something really obvious).

Thanks, I was just scared that It might be something else, I'm not particularly well versed with the causes of STOP errors (blue screen of death)

I have one more question, does the frequency of the CPU in any way effect longevity? I know that heat and voltage do, but I was just curious as to whether frequency did or not. I'm thinking of trying to hit 5GHz at a sensible voltage and seeing what temps are like.

I don't understand why people overclock cpus like 3770k... It's strong enough without overclocking.

Voltage/heat mean everything. If you are going past low 70's C in real world stuff like rendering? Yeah it is gonna hurt the chip in the long run. Games run cooler. Gaming and streaming run about the same.

 

Download Asus realbench and run a h.264. If you are low 70's or lower on the hottest core? You are fine and much better off then the new Mac Pro that renders at a insane 90C on a ivy chip lol. 

 

Voltage can kill a chip just like heat. Some chips don't like a lot of voltage through them. Bigger die chips can handle more. A little past 1.3 is prob fine on Ivy if you can keep temps down. You have the I7 and most people oc the I5. Your temps are gonna be different then many peoples listed, or the voltage they say is acceptable. HT adds like 10 degrees.

 

For instance you can go a little over 1.3 on an I5 Haswell. Try that on a I7 Haswell? Good luck cooling it. Ivy ran a little cooler, you may have more luck. 

 

5ghz on a Ivy I mean if you are benchmarking? I guess that is fine. You really don't need that speed though. You would need another 7950 to even see a difference in most games prob and it would only be a fps or two. A 4.9 Ivy is like a 4.5 Haswell (which many people can't even get) and like a 5.2 ghz Sandy. I don't know why you would need faster then that.

 

Bout the only games where you would see a difference is Guild Wars 2 and Dolphin emulator and Flight Simulator X. Every 100mhz would add a fps. What am I saying. Don't go buckwild. If you end up at 4.9? That is fast as hell lol. Go with the better temps over 100 more mhz.

Try Dolphin emulator, Guild Wars 2. You will know.

3.5 isn't the same as 5...

[nokturrduk84]

So what? You think if you have 5ghz you get 10-20 fps boost in games? It's just useless in games

I know exactly what sort of gaming benefits overclocking has, almost none past 4.2Ghz and not much from stock to 4.2,wiyh the exception of cpu bound games of course which benefit more. I don't use my computer for gaming much and the OP didn't give a usage scenario

Woah! Guys calm down I'm just doing this for the sake of benchmarking, I'd never run my system on a daily basis with a 5GHz over-clock! That's ridiculously fast. The only people I've known to run at 5GHz on Ivy are people who've de-lidded theirs. 4.8GHz is plenty fast enough, and stock is more than acceptable, I know. I'm just curious, since it seems like a decent chip; when I was bringing the voltage down, even as high as 1.270, the temp rise from 1.240 to 1.270 was only about 5 degrees.

I actually noticed this when benchmarking in cinebench, each time I added 100mhz, from stock I was getting around .05 points faster, but from 4.7GHz to 4.8GHz, the increase was only .01 points faster.

Yes, in games, at its hottest after a few hours playing games like Metro: Last Light (CPU intensive) the hottest core was running in the mid to high 50's.

For reference, I have a good 3770K. 5.1GHz at 1.35v with a budget 212 evo cooling solution, that's with just multiplier manipulation, I didn't even touch load line calibration when I was running it on air

Challenge accepted, I'll see what mine can do and get back to you.

Nice. Should put that bad boy on the cinebench R 15 thread. All Sandy's and Haswell's up there. We need some Ivy's!
