When is it time to stop Overclocking?

post #1 of 55
Thread Starter 
I've been browsing the forums lately, and I've seen hundreds of different overclocks. The obvious thing I've noticed though, is that there is no set pattern to overclocking. Obviously many people overclock for different reasons, whether it's to have a better folding machine, reach higher fps when gaming, or to push your CPU to the limit and benchmark to your heart's content. Hell, I wouldn't be surprised if some people try to see how much they can go before there CPU explodes.

Recently, I've come across a personal dilemma. I've been lucky enough to receive a chip that clocks to 4.6 GHz a relatively low volts. No doubt, I can push it higher, however, I ask myself if it'd be worth the hassle or not. Would using more voltage be worth another couple hundred MHz when it makes a negligible difference? This is something I'm going to have to think over.

What I'm truly curious about is how the members of this community limit themselves when finding the right numbers for their own 24/7 system.

Do you limit yourself by temperatures? If so, what is your personal threshold at 100% load?

Do you limit yourself by voltages? If so how much?

Do you limit yourself by a specific clock? If so what speed?

Does the CPU limit you? Would you try to get the highest clock you could for a 24/7 rig if you could?

Please state the CPU your currently using when posting your answer. Anything from a AMD Athlon to a Intel i7-2600K.

If a mod decides this thread will only escalate into a pit of fire with flames all around, then by all means, please delete it. I don't wish to start drama.

The reason I'm asking this because I've seen so many arguments in my little time here about what's considered the right way to overclock, but I'd actually like to hear about opinions without it escalating into a benchmark vs 24/7 stable war. I'm only looking for personal opinions, if you have a nice article to backup your opinion, great! Post it, so people can read at their own discretion, but please don't try to push your personal opinions and beliefs onto others! It'd be great just to hear another person's opinion for once without having to defend your own.

It's a mixture between voltage and temp. If temps are good but voltage is too high for 24/7 then that overlock is no good. Same thing if voltage is low but temps are too high.

So then it comes down to finding a good medium. 4.2ghz with 1.32v gives me good temps with also low volts. anything higher and the volts and temps go up where I wouldn't feel comfortable with 24/7 use.

Since you put such an emphasis on temps, what's your personal threshold for your i7 930?

for me its 75c. Anything above that and things are getting a bit toasty for my comfort. Luckily my Ven X can keep temps in the 60's at my overclock.

My sig rig is the first rig I have had that can OC. So for me I think I am limited by knowledge and patients. I need the machine to run, I havn't felt like OCing it to the very end that it can. BSODs can get to be very annoying. I found a point where I have found noticeable performance increase and run rock solid. I have yet to have a BSOD at my current OC and anything beyond has BSODed. So I think I have hit a happy limit for myself... For now.

A mixture of both temps and voltage. I'm more afraid of temps than voltage. Its time to stop when you feel like it. There are no limits.

Personally i think if you can get a stable clock within reasonable volts and temps (even if its 6GHz or something) then i don't see why you can't have that for 24/7.

I am able to get my 2500k to 5GHz @ 1.43v and my max temps are around 80C @ 100% load, so i'm perfectly happy to keep mine set at that.

With my 1055t i can get 3900 MHz 1.40-1.45v with LLC and 4000 MHz would require 1.45-1.50v. As for temperatures my NH-D14 handles under 1.45v really easily. There is not enough performance gain with 100 MHz to make it worth pushing the limits on voltage (1.5v) and temperature (55C). 3900 MHz with 3000 MHz nb plays just fine and keeps oc within safe limits. Thought i still need some stability testing, but seems to be stable so far.

Figures I'd forget to answer my own survey...

Intel i7-2600K

Do you limit yourself by temperatures? If so, what is your personal threshold at 100% load?

I personally don't feel comfortable going over 75c with the Sandy Bridge on a Prime95 run.

Do you limit yourself by voltages? If so how much?

While I'm not very experienced in overclocking, I'd probably stop just before hitting 1.4v.

Do you limit yourself by a specific clock? If so what speed?

So long as I can remain below 1.4v and 75c, I'd take whatever I can get.

Does the CPU limit you? Would you try to get the highest clock you could for a 24/7 rig if you could?
Haven't tried pushing the envelope yet, maybe when Ivy Bridge comes out, I'll see how far I can pass 5.0 GHz.

For me its all about the volts for 24/7 use.

I have a reasonable chip and can hit 4.2GHz @ 1.32v on my i7 930 and that is enough for 24/7 use for me. I don't see the point in running 1.4v to hit 4.4GHz since the difference in performance is negligible except in synthetics.

However, I do pump up the voltage and clocks when doing becnhmarking but that is for short amount of time. My 24/7 OC is 4.2GHz @ 1.32v, I don't feel comfortable going any higher.

Especially since I live in Australia and compared to most of you guys on OCN, have higher average ambients, I like to keep the volts down to reduce the heat. I hate seeing anything over 70*c under load.
