OK. With the new lower temps from lapping I wanted to try a new High OC and some benching. I was able to hit a new high OC with this new chip of 5.207GHz @ 1.576v:

http://valid.canardpc.com/show_oc.php?id=2552616

I was also able to bench
- Cinebench and IBT at 4.9GHz
- wPrime 32M and 1024M at 5.0GHz
- superPi 1M and 32M at 5.1GHz.

(I'll post the screensave proofs on the IVY Stable & Suicide thread)

My superPi 32M was 6m 40.572s - slower than feniks super maximus v extreme which did it in 6m 35.064s at 5.1GHz - good job there! thumb.gif



Valgaur, please update my new high OC to 5.207GHZ, and my temp gain to 26C.

Also, sandpaper I used for lapping was 400>600>800>1000. The 400 was very helpful with getting rid of the concave sinkhole on the top, and the convex bulge on the bottom of the IHS. redface.gif

I have heard in multiple places that there is little to no gain from anything beyond 800. (Anyone have some links that I can check out that note otherwise? I'd be happy to learn more)

SonDa5 is not kidding - my first try destroyed my first 3770K and cost me $300 to replace it. This is not something to try unless you can cover the risk of loss as not a few people have lost chips from trying this. eek.gif

1. Get to 4.5 Ghz

3. Run for 10 times (Also set as the default when program is started)
4. Report your HIGHEST temp doesn't matter what core it is reported from.
5. You can also show your temp drops but ONLY from the HOTTEST core to the HOTTEST core. (if not available refer to #4)
6. Ohh! If you have Lapped (sanded) your IHS please provide this information also. (Even what grains you used will be very welcomed)
Thanks again! This may be a ridiculous amount of info to be provided to join, but this is for research to see what we can show Intel eventually and how badly they messed up. (Yes I'm serious abort this part)
This is also for people looking into Delidding and seeing just how crazy their temps can decrease by Delidding.
Thanks yet again!

Looks great! Add it in and lets get some good data on temps and TIMs! thumb.gif

PCWargamer, grats on those clocks biggrin.gif

you seem to use kinda low vcore for your high clocks when compared to lower speeds and voltages you had before (and fully stable under IBT). I think the speed of your SuperPI 32M run at 5.1GHz, might be limited by error-correction (Ivy Bridge WHEA feature). can you check your Even Logs - Custom Views - Administrative Events if you are getting recent WHEA warnings after SuperPI run? higher vcore will fix it and it should speed up superpi even by 1-2 seconds too smile.gif seen it happening at 5.2GHz on my chip (using ungodly amount of vcore when trying to pass 3dmark) it dropped from 6m 31s down to 6m 28s when no WHEA occured during that run.

Valgaur, tried that stability tool from aida64, it's pretty cool! I don't know how I missed it ... for how long you usually run it when checking for stability?

You are correct feniks. WHEA errors at the time of the superPi run. But vcore is already at an very uncomfortable 1.56v for those 5.1GHz bench runs.

And yes, this second chip is odd in that it needs very high vcore to even boot 4.5GHz (~1.3v compared to my old chips 1.2V), and everything at 4.5-4.6GHz needs ~0.13v more to run - like prime95 and IBT. Yet the vcore wasn't as horrible as I thought it would be to bench around 5.0GHz. Higher than my old chip, but it could have been much much worse! smile.gif

Usually around 1-2 mins then i upped vcore a bit for IBT for 10 runs

IHS lapping ( 400 grit --> 800 grit --> 1000 grit). Read this composite pic from left-to-right and from top-to-bottom:

As evident in the photos, the IHS on this 3770K was quite concave, that is,
higher in the middle than elsewhere. "Flatness" was achieved in this case
when no more silver color remained on the IHS.



one uses wet/dry sandpaper and a flat surface (glass usually) to slowly and
iteratively grind an uneven surface. The goal of lapping is not be to make
a mirror surface, rather, it is to make flat surface.


waking up, g'morning smile.gif , and done some "info looting" while drinking my coffee wink.gif
saw you guys talk about sanding ihs etc ..so ..i like pictures, easier then 1000 (grit) words right ..lol
i must say, most peeps say it didnt help much, i thought the same till now,
1-3C max difference, others saw no difference at all, so im surprised about the
extra 11C tempdrop..

.....................................................................................................

First, here is the sequence of pics taken during the various stages of lapping.
To determine if the IHS was initially convex (crowned in the middle) or concave (like a bowl),
I used a sharpie permanent marker to make an X across the surface of the IHS:




Then I did just a few strokes on 220 grit before inspecting it,
knowing that the portions of the original "X" would only be removed from the high spots on the IHS:



very clear indication that the IHS is/was concave (like a bowl, the center was low and not touched by the sand paper yet,
the edges were high and have already been sanded down a bit, enough to begin to remove the permanent pen markings)

A bit more sanding with 220 grit yielded the following "copper ring" expected for a concave IHS:


We want all the nickel removed, nickel has a lower thermal transfer rate than copper, so I finished sanding off all the nickel with 220 grit:



check out how it looks after going all the way up to 3000 grit, love it biggrin.gif




if anyone is going to do this lapping thing,
note before and after results if you can,
might be usefull for others, we have this saying,
"one day of Sun, doesnt make a summer"..
so, results that one may have, wont mean others will have the same,

its like with the usage of different tim's on die,
took a while and results from different peeps, to be sure liquid pro/ultra are the best to use on die right smile.gif

o, about the "bowl" effect on that pic with the green markings,
dont forget if you put down the bracket on it, it will get less by the pressure...i thought..

well, to make sure noone will sue me, lol,
these are the original links,
