i7 @ 3.8. low volts, high temps.

[up2nogooduk]

Overclocked my i7 to 3.8.
Doe's the temps on idle and load look ok. as on prime it was near 100
And 1 core is 10 degres lower ?

Cheers.

Which CPU cooler u've got?Which case (good cooling))?

Oh yeah, would help lol
Hmmm, my idle temps should be in the 60's on load. not 100.
I got good cooling. do you think i should redo the past again, and use the past that comes with the cooler ? maybe i didn't put enough on ?

Blimy yeah. what's you'res on idle ?
I have 3 fans at the front, 1 on top and rear exhaust. and the cpu cooler.
What good it be ? paste not applied very good maybe ?

I did notice you abit choppy in games

sounds like our paste isnt on right

I'll redo it then.
Shall i use the Noctua paste that came with it. or silver5 ?

Cheers.

I'm running my i7 920 @ 3.8Ghz 1.28 volts using the same noctua cooler as yourself apart from i have removed both the supplied fans and are using 1 x scythe s-fex 1600rpm fan.It idles at around 35c & with 100% load the temps hover around the 60c mark,tim wise i'm using artic cooling mx2 and have applied this as per the instructions on the artic silver site which is one thin line down the middle.

Thanks for the link.

Considering you have HT disabled yeah those temps are really bad, it must be poor heatsink contact.

Don't leave QPI & RAM voltage on auto as it will raise them really high when overclocking, both those voltages will affect cpu temperature as they are on die.

My i7 920 at 3.8GHz (HT on) runs in the 75-90C region full load but I have low profile cooling and warm ambient temps (central heating on )

What shall i set the QPI to, same as cpu volts ? and what does that HP meant to do, is it a good thing to have enabled ?
I best take the board out and redo the past etc

Try QPI on 1.3V-1.35 for 3.8ghz, it doesn't have to be the same as CPU volts no, just make sure that QPI voltage and DRAM voltage are within 0.5V of one another (so with a 1.3V QPI keep DRAM volts below 1.8V).

HT = Hyperthreading, it basically gives your CPU 4 more threads and uses areas of the CPU that would be otherwise idle, obviously the more of the CPU that is being used at the same time the more heat is generated.

EDIT: If you download "TurboV" from the Asus website you'll be able to see what volts your QPI & DRAM are being set to as they aren't shown anywhere in the BIOS, I remember when I left those voltages on auto they got set really high when overclocking.

Done that. can i use this turbov to adjust it ? and also the BLCK ?
Or best to adjust in the bios. My ram i put at 1.64, as it wouldn't go to 1.65, just goes to 1.66. my ram is meant to be at 1.65.

Cheers.
