i've recently purchased a D0 stepping CPU.

Now i need some advise with clocking this on an Asus P6T Deluxe V2.
Are there additional settings i need to increse etc to make things run better?

I've currently got it running at 4.2ghz @ 1.32v on stock cooler and ram @ 1.64v @ 1600mhz

any advice would be appreciated

i've got a TRUE 120 Black arriving tomorrow with two Xigmatek fans to help cool it aswell so that'll help drop temps down.

i've not run OCCT or Prime yet as i'm only on stock cooler so will drop it down to stock for now.

Can we see a screen of prime? With temps?

:cool:

wont know anything from current overclock until i can run with a TRUE installed. Will it wont it. how high how low. Hopefully we'll find out tomorrow
 
can someone tell me the best temp software to use please.

I've currently got realtemp and coretemp but both are showing different temps.
realtemp: 34, 31, 34, 31
coretemp: 43, 41, 43, 41

which one do i believe?

also coretemp isn't showing my VID. How do i get to know this?

on stock cpuz has my core voltage @ 1.208v

For me at 3.9Ghz/1.28v with C0 i7 there's no difference in temp between realtemp or coretemp (idle & load) so I'm guessing it's the D0 microcode throwing one of them off a bit. I'm tempted to trust coretemp at those fantastic realtemp figures though, bit too good to be true ;)

We can hope though!

cheers for the reply. Coretemp it is then.
Shame really as those realtemp figures are ace :cool:
 
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.
 
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.
 
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?
 
yes a bit of research on all these new settings is needed to understand it all properly. There are a lot of options in the bios set to AUTO which may not need to be.

Will bench @ current settings tonight then possibly play around with voltages to see if it'll come down anymore.
 
i have set the TJMax @ 95deg (still unsure what is best) and these are current temps after 20mins Prime.
Even though prime says different to bottom right corner.

I'm thinking i could lower my voltage for the cpu slightly as in the bios it's @ 1.34v but also cpu-z is showing the multiplyer as 20 and once rime finishes it jumps back to 21. Why is this?

can anyone offer any explination as to why cpu-z drops my multi to 20 from 21 (including turbo)?

i'm thinking i may try and get it running at 210x20 and turn the turbo function off.
