SimC33 ought to get around to a new thread, real soon now, but last I knew he was working on 4.4GHz. This placeholder thread ought to do till the Official-Official thread gets up and going. Perhaps we can save our new stability runs here.

I did a 4.7GHz run yesterday but did not bother to post it since I could not tie or claim the 1st spot   I think I will just re-run things later down the line if somebody takes my 2nd spot lol.  With current temps there is no way I can go any higher.  I doubt though anyway that I can LinX burn anything higher than 21x226MHz.  It did not seem yesterday that the chip would take it and without Phase or better I am not willing to put 1.6V through it.

Who would have thought 4.7???!!!
 
The other day I was reading some forum somewhere, populated by what I would call professional overclockers, and they weren't too concerned about blowing it up. Out of a few thousand samples, they had only seen ~five fail. Those they were perfectly willing to call infant mortality or manufacturing defects of one type or another; but that was for many of our over-volt experiments, not for Vcc over 1.55V. For that, need something better than plain water -- but on LN2 it seems, although not generaly confirmed, do whatever you want.
 
One person uses a small gutted refrigerator.
 
Re-running my 4.4 LinX test (HT Off) cause I forgot to put my name on the screen shot. It seems to like 4.4 all day long with no problems, but will NOT go 0.05% higher no matter what I do. To me that doesn't make sense, but I have to believe my eyes.

So will we have to re-post all our screen shots?

I don't know if we know what we're going to do. [edit] I just want to post my new one, if it ever finishes LinX.

This is a club for the EVGA community for those of us who love and enjoy to OC our core i7 CPUs. It is for those who wish to post their results and build our comminity to help others if need be in reaching a goal they wish to achieve with their rig.

In order to join Club i7 Stability , you must post ONE screenshot containing the following:

1. At least 20 runs of Linx passed with no errors, using a problem size no less than 25,000
(This will require your system to have around 4.8 GB of free memory, which should not be a problem for the majority of core i7 users. Allowing Linx to load and then unload seems to free up some additional memory.)

LinX 0.6.3 IS A REQUIREMENT!

LinX 0.6.3 can be downloaded from this site and I will keep it updated to the newest version for future people to see and use.

http://www.xtremesystems....howthread.php?t=201670


2. CPUz front tab showing your overclock, voltage, and threads.

3. Real Temp showing your min/max temperatures before and during linx.

4. Include a notepad shot with the screenie having your EVGA username DO NOT DO IT SEPARATELY...include it with everything else for ONE screen shot. Example:




It eliminates the chances of accusation of the results being fake or not theirs



5. HT is your preference, but the stats will be divided into two sections. HT on and HT off

6. The i7 MUST be OC'd to 4.0Ghz or above. (Those of you who have 3.8,3.9 etc...I encourage you to reach the goal of 4.0 and enjoy the process of getting yourself there.)

7. Please post the following ABOVE THE SCREENSHOT:

Core i7: (whichever you have)   Batch #:
CPU clocked at:
Voltage:
Idle temps:
Load temps: 





Here is the link and a picture of the badge for our sigs for you to show (if you choose to do so)

We will also organize the from highest Ghz to lowest...

This allows you to show your hard work into making it more stable than before.

TRASH TALKING IS PROHIBITED...

We are all here on these forums for a reason and that is to converse about things and give each other guidance and help for whatever need it may be.

Please read this if you get the urge to lash out at someone or someones views.

I hope to see everyone posting their results and this club for EVGA really take off. Thank you for your time and LETS SEE THOSE RESULTS!!!

Good job!

I gave up on 4.0GHz HT on.  Not going to happen.  I guess I just have a bum chip.

I run 3.7xGHz 24/7 with HT on.  But the jump to 4.0 HT on requires a .1v increase.  I thought going from 133x30 to 160x25 would really help me.  It actually did help my core temps to increase bclock, but my motherboard can't take it.  The chip still needs too much power.  My chip topped out at 85c after about half an hour but kept BSODing for IRQ_less_than_or_equal or BSOD 124.  I went back and forth increasing core voltage for IRQ_... error and VTT for 124 error and things were looking good.  CPU temps stayed good.  I thought I was almost stable.  So close.... BSODs would happen 30-45min in to Linx test.

But my motherboard can't handle that sort of power draw.  VREG temps were reaching almost 90c and NB was exceeding 80c.

I don't even want to think of this, not at all, I am very lazy, BUT, let's swap processors as an experiment. I'm an engineer and since all of us OC'ers represent ourselves as great empirical analysts, let's just swap.
 
We, you and I, can document for all time, the great test.
 
If you can't hit 4,357.3MHz with my chip, then we'll swap motherboards, etc. etc.
 
I really hate the hassle, but someone ought to try this sort of thing.

That last thing I wrote wasn't my main idea, though.
 
Do you suppose that your Vreg and/or NB could be heatsink related? One or the other I could believe.  But not both.  I don't know.
 
It looks like it's room ambient or case system temp problem, although we can hardly call room temp a problem -- it is what it is.

Okay folks, let's go. The new official page

Update for you Grd.

I have other things I should have been doing.  But I decided to screw it and take some "me time".  I did the thermal paste swap on the NB and Vreg.  Vreg was VERY fiddly to get it right.  I took the thermal pads off the Vreg and then applied thermal paste.  I mounted the vreg and removed it and saw that I had zero contact in the middle and light contact at the edges.  I filed down the vreg mount standoffs to increase edge contact and bent the middle downward and remounted.  I repeated this process over and over until contact was excellent.

Now, my idle Vreg temps are ~50c and loaded vreg temps are ~60c at 3.73GHz.  That is AMAZING!  My loaded Vreg temps at 3.73Ghz before were around 75c.

So, later on when I have more time, I will try 4.0 again.  There should be no reason I shouldn't do it with HT on now.
