I7 Temps

[Greg_77]

Hopefully as data is added to the spreadsheet, we will get a better correlation between overclocking potential and batch number. Until then, we can all sleep knowing we can overclock to at least 3.8 GHz 😀

The following article from AnandTech concerns overclocking and batch numbers: Overclocking Core i7: A Tale of Two Retail Processors - http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3502

3.8Ghz sounds nice but i really want to get a 4Ghz overclock because it just sounds cooler... i know thats such a normative comment but come on saying you got an i7 to 4Ghz to just sounds so WOW lol well lets hope i can get 4Ghz (CPU coming in 3 Days and TRUE 120 Black in 6 Days...)

Lol CompuTronix's link just proves its based on Luck when overclocking (im shafted i've never won anything never mind being lucky enough to get a good OCing i7 🙁 )....

Well even if batch # was extremely important to overclocking capabilities, the only way you can guarantee a particular batch is by buying second-hand or in a brick-and-mortar store. So it's usually blind luck either way.

 

[Greg_77]

It seems I have a good batch number (3835). Hopefully I get a nice overclock.

🙁 my i7s been delayed my snow!!! !! come on thats so unfair!!

 

[OmegaStalker]

anyone here got an 4ghz 920 overclock? post your figures.... temps, volts, batch no, and cooler...

 

[Greg_77]

I feel my idle temperatures may be high on my new build. My i7 920 at idle is 35 C (realtemp) using 100 as my TJ max. My ambient temperature is about 72 C. This is with a coolermaster V8. Does anyone have thoughts on this?


Also, this may seem like a strange question, but can faster ram speeds result is a hotter processor?

 

[randomizer]

Ambient of 72C? You're tough! :lol:

i7 uses alot of power and is a miniature furnace, somewhat like Prescott, but with performance to boot.

 

[Greg_77]

So, that is a good temp, even if I overclock? Just curious, because I have seen people post temperatures lower than mine at idle. Keep in mind, my processor has not been overclocked yet.

 

[randomizer]

They might have lower ambient temps too. Ambient temp is very important on air cooling.

 

[Greg_77]

Will, that's good to know. Now to the next question, why is my ambient temperature so high......... 😉

 

[randomizer]

I'm sitting in a 30C/86F room right now 🙁

 

[cjl]

I just tested mine at 2 RAM speeds - DDR3-1066 and DDR3-1600 (I have Dominator 1600-8-8-8-24 RAM), and mine definitely runs a couple degrees hotter at DDR3-1600. Maybe it has something to do with the integrated memory controller...

 

[Greg_77]

Thanks cjl, that is interesting. I am going to lower the ram speeds in my pc and see what happens to my temps. Randomizer, what is your processor temperature at that ambient temp?

 

[randomizer]

Well Real Temp will tell me my E6600 idles at 56C. After calibration, Speed Fan will say 15C lower than that. Something is not quite right with my CPU, but there is no way to prove it without destroying it (removing the IHS).

my i7 will be here monday and my rams coming tuesday and then im going to write a post showing my exact journey with eveyr step and every component (and every guide i've used so far) i think it would be a good idea as im a NOOOOOB lol and its my first build and my first overclock so it should help everyone out there that has as limited knowledge as me.... (note i'm too poor to afford a cooler and proper GPU just yet so it only will be a mini guide with a highest safe stable on a Intel heatsink, but i'l get them in a month or so)...

 

[russb123]

I have a Asus P6t and a 920 i7 (overclocked to 3.2) 1.35v 160bclk 1604mhz mem

Room temp is 72 degrees F (which is 21c i think)

Idle temp 33

Load with prime blend mode tops out at 55c

Question?

Software called AI suite came with my motherboard and the temps are alot different then what Real Temp 3.0 displays. Which is more accurate? AI suite is 10+ degrees higher under load!

The hardware monitor in my BIOS agrees with the AI Suite. The temp is shows when I am fiddling in my BIOS is around 40C and when boot into windows AI suite shows 41C. Real temp shows the 33c I listed above, which is way off from the BIOS hardware monitor.....how can you know what to trust?

 

[Greg_77]

Set realtemp to 100 TJ max, and it should be fairly accurate.

 

[randomizer]

It will probably already be at 100C. i7 contains Tj Max (or Tj Target rather) within one of the Model Specific Registers so that software can read it. If Intel changes it, we don't have to work out why people's temps suddenly don't look right because the new value will be used automatically. Of course, the "real" Tj Max is subject to caibration error of an unknown amount so there is always going to be variation.

 

[russb123]

So realtemp is probably more accurate?

I keep reseating my waterblock because the temps seem higher than they should be in the BIOS and with the ASUS provided software.

If realtemp is correct I am right where I want to be for temps.

Read ComputTronix's temperature guide at the top of this forum. It doesn't yet apply specifically to core i7, but it will help you understand temps a bit more. As I've said before, accuracy is arbitrary.
