i7 920 D0 Stepping

when my clock was at 4.2ghz i had the Bios set to 1.33 (from memory).

Never really noticed the voltage drop much more lower than 1.32 but if i'm honest i wasn't paying attention as it was only at this clock for 10 mins or so cos of being on stock cooler.
 
Ok, nice. I set 1.325 in bios and I think it shows 1.28 or 1.29 in windows but doesn't move any more. My only gripe with this mobo after owning an Asus before.
 
Its 57 C at 4.2Ghz on the stock cooler, I'd say that was pretty good. Mine idles at 40 C at 3.8Ghz with a TRUE and push pull fans.

Much of the idle temperature comes from the ambient temperature and case fans which is why the OC doesnt impress me much.

In fact mine did around 55c when I clocked it that high at stock and its an older c0.
 
The fact that he can get into windows @ 1.325 @ 4.2 using the stock cooler is not bad IMO. Time will tell ...
 
but as i've stated i can't and will not run prime/occt until i have my true installed for suficiant cooling.

pointless proving it's stable @ 4.2 on stock cooling when i know it'll die.
If it's not stable @ 1.32v i'll up it to 1.4v.

but 4.2 on stock straight out the box i feel is quite impressive
 
right i have my true installed but with an old fan attached.
temps @ idle in coretemp are: 40, 37, 40, 37

is this good or bad?

also with overclocking an i7 i've noticed a couple of things which are annoying.

Loadline calibration needs to be disabled i've found.
When it was turned on Prime kept failing. i even had it running @ 1.39v and it failed with it turned on.

Once disabled it is now in cpuz @ 1.336v and bios @ 1.34v
Ran prime for 15mins last night at these settings and it ran fine yet the voltage went above what i'd set in the bios and it was still fine! why is that?. Temps got to mid 70's - is this good or bad?

and once it was running i had cpuz open along side and noticed the multiplier was only reaching 20 when the turbo within Asus puts it to 21.
Once prime finishes it goes back to 21. Why is this?

also the tdp has now gone from 130 to 147 and also drops to 43.7. is this normal?

Why dont you show us a prime95 or linx run? I'm not impressed so far

which part of my above post did you not read? all of it?

i mentioned it kept failing until i turned loadline off. By this time it was 12.30am so i decided to go to bed instead.

to satisfy your needs i'll run it tonight and hopefully give you the answers you've been wanting.

and also because of the voltages jumping around i was unsure if there was anything wrong which is why i've asked above.

They are just trying to get a reaction from you mate - 70 seems pretty reasonable considering how hot these chips run and your current cooling. 4.2 stable on air without much effort is pretty awesome IMHO.

Your erratic settings are probably due to the fact that you have most of your settings on auto and also turbo function.

cheers for the reply beh*. Being new to i7 i didn't want to run prime through the night with the voltages jumping around like they were incase anything was wrong.

also i've found that coretemp is still being worked on for i7 as they aren't reading the TDP correctly and i need to calibrate the TJmax which is why coretemp is reading higher than realtemp.
 
Your idle temps are about the same as mine with my chip at 3.8Ghz.

I'll have to give mine a proper under load test. I couldn't get mine stable at o ver 4Ghz, think it would need a lot more juice.
 
at the moment i'm trying to find out what the TJmax is of an i7.
A lot of people are reporting 90 or 95 compared to the C2D 45nm @ 100.

I've noticed i've got realtemp @ 90 and coretemp @ 100 which is why i'm getting different readings. I'll put them both at 90 i think. Does this sound aceptable?

So with the voltages not being a problem and temps seeming fine i'll run Prime tonight. What test should i run? Blend or Small FFT?
