temp is too high, id like to keep it below 60C, but i dont know what the fuck im doing i found these settings from the internets. some gypsy with same mobo and chip posted. the temps will fall more than few deg after 200 hrs, but still will be too hi.

healp !

For some reason Vcore 1.28 seems a little high. Could be why you temp is too. I would start there. I'm no expert, I've only scanned different forums on the i7 chip. 2 cents.

Lower voltage = cooler
Lower clock (speed) = cooler

You can't lower voltage and keep high clock because it will be unstable (underpowered) and you'll get Blue Screen Of Death (BSOD).

You CAN try to lower voltage a notch down in BIOS, test with Prime. Repeat until the lowest STABLE voltage (keeping your clock set to 4Ghz) is achieved.

If you still don't like temps, either turn your cooler way up and case fans way up, or drop voltage + speed to whatever temps are good for you. As always, I stand by anything under 55C and you'll have a chip that will last as long as a stock one. It's ultimately YOUR call.

thx guys. im yet to figure out ram settings... so what would "match" the cpu setting i have now ram-wise ?

best 1500 post reference available, these guys know i7 inside out.
like BJ said, lower volts mean less temps. although you can lose stability. trying to 4ghz on air at 60C is going to be a feat of its own imo. lower ambient temp?

 

[47]

put 2nd fan on, no difference LOL

4ghz

improved ram timings a bit to 8-8-8-19

43 / 75 temps

i am not understand

 

[Dean]

your temps are fine, almost every air cooling setup for an i7@4ghz pushes 70-80C on full cpu load, idles around 40-45C.

 

[OG buckshot jr]

Dean means your temps are normal when compared to what other people (namely, IDIOTS) are doing... Your temps are too high. 55, MAYBE 60C max. Period.

if you look up your chip you will see it is rated by intel to a maximum temp of 68C.

if you can overclock it and keep it below this threshold then you should be good to go. like buck says, you will need higher volts to maintain stability at higher clockspeeds, and this brings your temps up...

there are things you can do depending on how crafty you want to be. ie: your video card likely heats up the ambient temp inside the case, so you can try partitioning it, or ensuring proper airflow through the case. crank your fan speeds, heck maybe u can overclock your fan voltage and increase its rpms (id rather replace that than the intel, lol!)

 

[47]

i got the haf932 case.. epic airflow


problem is that i dont know what im doing, the 4ghz setting i found on the internets. i cant change them. the 3.7 setting bj gave me crash

 

[keyzer_soze]

its trial and error -- even two chips that are the same will overclock slightly differently because of tiny variations. so person A might get it stable with one setting while person B might not..

i'd drop your voltages back to normal and then increase your FSB speed bit by bit checking stability. increase the voltage as you need to and without getting too hot

i think at 4ghz (which is a fantastic overclock) you might need even more voltage..

also, optimal ram settings depend on your ram. what u got?

 

[keyzer_soze]

ps: how did you get it to 3.7ghz? and it crashes? looking at your screenshot and the intel specsheet i linked earlier, i would think you'd have to bring your cpu voltage up to get stability (intel lists the max as 1.375V and you are only running 1.2V). some mobos allow micro adjustments which isnt a bad idea either

you definitely want to bring that temp down tho or its only a matter of time before you cook the cpu

 

[47]

im running 4ghz stable as fuck, but i dont like the 75 load temp. what i did was just copied some dude's settings who has same chip AND mobo. thats y it works exactly the same. i wanna run slower and below 65.

 

[Leroy]

Ok, noob question here, its about time I buy a new mobo and chip, so I'll probably start overclocking hte old one, however, anytime I do, I have stability issue, and it actually makes it slower as it throttles itself down.

I'm not sure the make/model of my fan/heatsink, but I

1) redo my thermal paste every so often
2) Have both active and passive cooling (fan, heatsink)
3) Clean the fan somewhat often

I have a cs load temp of around 70, and its a 3.2 dualcore intel somethingorothere?

Thoughts? just fuckered?

 

[keyzer_soze]

leroy, those temps are normal or overclocked?

if your computer is unstable you need to give your hardware more juice. so, say you overclock your FSB, then that will increase the frequency of your CPU and your memory also, so you should boost the voltage to both of these things.

if you have an unlocked cpu (this applies to you also duke) then you can increase the cpu multiplier without increasing the FSB frequency, which is often more stable. then you can make a small adjustment to the FSB for more performance.

whether 70 degrees is too hot depends on your exact cpu. mine's probably at 70 right now and i've been running it overclocked for almost 2 years.

finally, what do you mean by throttling leroy? i am not as familiar with intel chips as i am with amd, but amd has a "cool n quiet" function which can adjust the cpu frequency and voltage on the fly.. you might want to disable the equivalent feature in your bios so that it isnt messing with your settings

good luck!

 

[Leroy]

no overclocking, and what I mean by throttling, is hte CPU will dial itself down to prevent damage? Correct?

 

[47]

cs load temp of 70 is high as fuck.

what are your idle and load temps ???

u might be way too hot and it protects itself from bbq


ok, i run css at idle temp of 43. it gives me like 1% load , lol.

do this leroy: DL "core temp" and "prime95" . start coretemp and run prime 95. post temps.

 

[47]

@ 3997mhz temps fell from 75 to 72, as arctic silver promised hopefully it'll go down some more, ive heard it goes down as much a 5 deg.
