New to overclocking and have a few questions.

post #1 of 10
Thread Starter 
So I have played around with overclocking in the past (air) and a little bit with (water) but I was really just following someone else's numbers and there system didnt even match mine, not even the processor lol. The way I started with my video card was to slowly bump up the card and its voltage in small increments and then test it until I get errors and then go back a chunk and then go up in smaller chunks until I get a solid stable number. (Still working on that too btw). Is this the same way with CPUs. For the graphics card I am just bumping up the MEM Clock and the GPU Clock and the voltage. Is this even correct? With the CPU i only know about the multiplier and the voltage. Is there anything else that needs to be adjusted properly? What are the limitations? Temps? Specific voltages? Multipliers? Very new here and if anyone can help me out or point me in the right direction I would be greatly appreciative.

I don't even know if this is the right thread, I looked around, but didn't see anything specifically for overclocking. Where could I find some information about putting my ram where it needs to be. It auto starts it at 1333 and I would like to get it up to its potential but am LITERALLY CLUELESS. Thanks in advance and if I need to move this thread just let me know and I will make it happen. Thanks again.

1. clock speeds increase heat linearly, so 10% increase = 10% increase to heat output. (keep in mind heat != temperature)
2. voltage is going to increase stability for ultimately a higher overclock, but also increase heat by a more than linear rate.

so, you want to add clock speed until the system either wont boot or crashes during a stress test.
if you REALLY want to fine tune it, watch temps very carefully at this point, but add a tiny bit of voltage until it becomes stable. it is not recommended to go over 1.275V unless you have outstanding water cooling or better, say a dual 120 or dual 140mm radiator or better.

so yea you definitely dont want to add voltage unless you need to. for all you know the processor is capable of 4.8ghz at 1.275v (that would be considered a golden chip)

Awesome thanks. People like you are truly under appreciated. I was playing around with it last night and got to 4.7 and had temps around 30C (Which I am currently wondering if it was incorrect and more around 40C). I have 360 xl Rad and a 240 Rad all with 5400 rpm pull fans. The 240 has two 4200 push fans, and the 360 has two 2300 (for aethetic reasons) push fans. As well as a few others pushing cool air into the case. If I am not mistaken I should be able to push the chip pretty high. I have a few more questions if you dont mind, or if anyone else wants to chime in ( I love great conversation smile.gif )

Is there a limit I should stay away from in terms of voltage and heat. Also is there a different program to monitor temps other than CPU Temp, as it currently does not work with windows 8.1 and Haswell-E chips.

80+ celsius under full load (like prime 95 testing or your most intensive game) is something you want to avoid, the cpu will throttle and underclock itself once it hits around 100C. also 1.4v is considered a ceiling for overvolting. you can go higher just for overclocking reasons and maybe burn in but its not something you'd want to run it at 24/7.

also keep in mind if your ambient temps raise by 5 degrees (18C increase to 23C during the middle of summer) expect your cpu temps to go up 5C too

So I played with it a bit, and I could only get it to 4.5 at 1.279. Bumped it up just a tad to get to 4.6. However, when I view it on CPU-Z its only showing 1.258V. Whats up with that? Program wrong?

use more then one program to check value, many value can be wrong in some program so it s better to check with another if it s more or less the same.
you can try hwinfo , it s very good i think

yea cpu-z has issues just go with what your motherboard is telling you.

have you run prime 95 synthetic? make sure adaptive voltage mode is shut off you want it on manual. then once you're done stress testing, you can turn it back to adaptive to save energy. adaptive mode causes voltage to go above the maximum that you set when you have it set to adaptive mode. that creates too much heat for newer systems.

Awesome thanks guys. Ill check those out. Slowly getting a feel for all of this, copied someone elses at first and was at 4.7 @ 1.42v, where as I now have 4.7 @ 1.384v so its nice to know that I can do it on my own now and get some lower voltage with the same results.

to be honest even with good increase of voltage when you push the chips to it s limit you start having stability issues in games sometimes even if you were fine in bench . it s good for bench but i don't think it s worth it to push it too hard for everyday use. i sometimes even see lost of perf from 4,4 to 4,6 ghz both in games and in some bench.

@ashuiegi, I absolutely understand. I am going to leave my CPU at however high I can get it at 1.28 for normal use. I think its around 4.4. However, from this point forward its just learning about pushing the envelope. The highest I have gotten it so far is 4.8 @ 1.48v. My goal is to get it over 5.0. I am so close I can taste it, but once again, I want to learn from this, not just punch in some numbers and get 5.0. Still reading, still sifting through this this websites abundant and never ending forums like I'm on some MMORPG quest line. Loving every min of it smile.gif
