hia ive got an i7 cooled via a H50 with one fan at the mo. gotta get other fan from my bros house for push pull. ive recently applied some arctic silver 5 thermal paste to my cpu as i thought the reason it was overheating was the lack of old paste on cpu. it would idle b4 at stock setting, (1.21v) 2.66 GHZ) 38 degrees Celsius. after applying new paste it still idles at 38c.

put 1.38v @ 3.99ghz through prime 95 and its jumps rapidly up into 90's. this isnt right whats going on???
 
are you using auto voltages? and how much thermal paste did you apply? what cooler you using aswell? thats way too high imo
 
no im using manual V, currently at 3.3 at 1.24V. its cooled with a corsair H50. i put a pea sized amount on CPU spread it out over CPU, then applied more where need.
 
1.38v is quite high to get 4GHZ.

The h50 isnt really an high performance cooler TBH.

Try lowering the volts abit, and re apply the paste (pea size in the middle).
Make sure that the cooler is securely fitted, and also check that the pump is working (plug it into cpu fan header and check rpm in bios).
 
what mb? so its fixed voltage not using dvid or voltage offset? 4ghz you would need around 1.25-1.28v imo,but depends on your chip,and what qpi/vtt voltage or dram core voltage you using?

ive just applied this paste about an hour ago. no different in temprature to the paste i was using b4 which I wasn't confident about to cool the CPU because of the amount I had available. pump is at 1300 RPM.

G1 sniper X58. the only voltage i touch is core voltage. not sure what the rest are at? would they jump up to a high V automatically when V core is increased??
 
only 3 main voltages to look at and set manually with x58 imo,are qpi/vtt,dram and cpu voltages,tried lowering to around 1.25-1.28v for 4ghz? qpi/vtt i would set to 1.32v-1.35v for 6gb of ram @1600mhz and dram i would set to either 1.5v or 1.66v,you ram voltage will be printed on your ram

you will need to test for stability ect and tweak voltages,may need more may need less,core voltages should be kept under 80c

kk thanks.

dont you think 38c is a bit high for stock settings??
 
not if its running fixed voltage of 1.24v,once you get it set up you can use dvid and cpu will idle much cooler as voltages will drop to around 0.985v ect and only use 1.24v at full cpu load

where can i find DVID? fairly new to x58 bios's so you'll have to forgive me 4 being a noob. lol
 
it only unlocks when you set cpu voltage to normal setting in cpu voltage list,then look at what cpu voltage is and tell me,you need to find out what voltage you need to be stable at 4ghz and subtract the amount normal sets from the stable and enter that into dvid,so say 1.2500v is needed at 4ghz,and normal sets 1.2000v in dvid you would enter +0.0500v, and so on,use a calculator

1.2000v add 0.0500v = 1.2500v (just an example)
 
Have you got any screen shots with CPU-Z in with the speed and memory tabs etc so we could advise perhaps overclocking it?

My D0 manages 4.2Ghz at 1.3vcore but then I have a different cooling setup.. Might be worth having a look into setting the vcore lower to start with and see how far it will go before you have to start adding more...

ok so im stable at 1.21 for 3.7 with qpi/fft (whatever its called) at 1.34. but im getting this weird whinny noise coming from teh back of my motherboard. certain its coming from back of cpu. quite annoying. any ideas what that is??
 
When you say pea sized, do you mean a blob about 4mm in diameter? "Grain of rice" is probably a better choice.

Aside from that, the 920 runs hot. It's around 200W when moderately overclocked, that's a huge amount of heat to remove from a very small area. So, it'll be hot... below 100 is probably good enough. Below 80 would be rather nicer, but might not be possible with your cooling & room temperature.

so my corsair H50 inst a good cooler?
 
if u want water cooling then u have to build it yourself

h50 and all these coolers are just provocation of watercooling
 
If it helps, my i7 920 C0 has never been cool. 3.96Ghz @ 90c Max in IBT with a Coolermaster V6GT @ 2100RPM @ 1.375v. It requires over 1.4v to be 4GHz stable. It's an old chip, bought in the first month of release.
However, it is rock solid and is running fine and stable still to this day.
 
CPU/mb whine or squeal is usually caused by c1e power saving states,go in advanced CPU features and disable it,then in win7 power saving use balanced profile,lemme know if it stops the noise
 
If you think it'll help with a few screen shots then please do post some up :) We might be able to help you :) Has the unit been cleaned at all? By that I mean is the rad clean and free from dust? That might also be a factor as sometimes they can get very dusty.
Also what sort of room temps are you in roughly?
