Thanks very much to jaded for the banner!

Thanks also to i7bigrig for laying the foundation of this club!

DISCLAIMER:
This isn't an easy club to join. You might even consider it exclusive. Most likely you will pull your hair out as you realize that your overclock fails. I take no responsibility for any emotional distress, or for any resulting physical damage to your CPU as you realize your voltage is utterly lacking. You have been warned.

Now that the core i7 has become widely popular, overclockers worldwide have been pushing this new chip to its limit. If you are reading this now and own a core i7, chances are you overclocked it. Here is the problem, most people overclock the i7 and think they are done and stable, when they are actually far from it. Overtime, instabilities will cause severe degradation of the chip.

Is your overclock 100% stable? That is what we are going to find out today!

In order to join the Core i7 100% Stability Club, you must post one screenshot containing the following:

-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.)

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

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

Substitution of similar programs, such as CoreTemp for RealTemp, is certainly permitted so long as the parameters above are strictly followed. Trading LinX for IntelBurnTest is a bit more difficult, since as far as I know the problem size cannot be specified in IntelBurnTest.

As people post their screenshots in this thread, the list below will be updated with the highest stable overclocks on top, and the lowest stable overclocks on bottom.

Is your core i7 100% stable?

Links to the programs you will need:
Linx: www.youwatched.com/datajay/linx(0.63).7z
CPUZ: http://www.cpuid.com/cpuz.php
Realtemp:http://www.techpowerup.com/downloads/1325/mirrors.php

Note on thread takeover:

Since many of us are still interested in participating in this club, I'm going to get to work on updating the thread to reflect verifications since i7bigrig last made changes to the list. This may take some time, so please trust that the end product will be worth both my time and your patience.

*Any errors please below, please send me a pm.
*If any members are updating their overclock, make a new post with a screen shot showing your updated overclock.
*I will try my best to keep this updated as often as possible, thank you!

For me with Vista ultimate the most RAM I can get is 4500?
thats MAX ram

Edit:
Fixed it no idea how.
Screens here

One with "All" ram last night, resulting in 110 succesfull runs today.
Restarting LinX gave me the option for a whole new higher "All"
Just did 20 runs because I'm bored and want to play some games xd

This is true with all PC components, when xxx program is known to clearly generate the most stress, use it, when xxx hours is known to represent 99.99999% stability, let it run that long. Some people don't seem to believe that. Anyway you'll be hearing from me again when I finalize this 4GHz

Can't wait to see your results!

People should definitely care to be 100% stable, it has been shown that anything less will result in the degradation of your chip over time! You don't want random electrons jumping where they shouldn't be.

Update: I've also now started the core i7 100% stability club! You are in once you upload your pic

Nothing on the RAM Problem?
Might be a very lonely club if there are more people with my problems.

Wait... why is vista maxing your ram at 4.5gb? Are you on the 32 bit version?

 

[Inktfish]

I'm on the 64 bit version.
If I select all ram I get this: 4536
This means a problem size of: 24331.
I think vista uses more resources than Win7, therefor the 25k problem size isn't possible for me.

Can't you change it to "All" ram?

Can you try to free up some system process for that extra room? I'll try to rethink the rules if its too difficult, but if you can disable some of your tasks such as windows update, any open browsers, or unneeded background tasks you should be able to get 4.8gb free.

Give it a shot, and let me know.

For some unknown reason I have 5143 free RAM atm...
Results will be coming back

(More than 25k problem size a problem?)

Not at all =P Just make sure to have cpuz and realtemp in the ss as well.

Good luck!

Updated my first post.

Grats! You are now 100% Stable!

Club Sig code is now in the OP

Also +rep for being the first =P

 

[Blameless]

I don't really think you can claim 100% stability if only one stress test is used, especially after only 60-80 minutes of it.

LinX is pretty handy, but it doesn't find everything.

You do make a good point, but I figured a balance would be best. I don't think people would be very willing to go through hours and hours of linx and other stress testing programs.

Besides, 20 runs of Linx with a problem size of 25000+ is going to catch ALOT of people's instabilities

It definitely caught alot of mine, and I'm glad it did, otherwise my i7 would have been running undervolted and unstable, even though prime95 blend & small ftt 24hours+ said otherwise.

Yeah, it will certainly cull the vast majority of the superficially stable.

Indeed, and I think its doing most users a favor. If you run your chip superficially stable, it will only harm its long term life. People shouldn't delude themselves, and this is the test that will bring them with a nice rock hard slap back to reality.

 

[Inktfish]

Do more than 20? xd
I mean
beat my 110 runs ^^

btw bigrig

I hope you're studying in the marketing/economics/sale section or are already employed in it.
You are pretty good in promoting things, in this case the club.

*casually walks by to take the crown*

Under load, while crunching the last run

Done, idle temps right after this hour of crunching. The waterloop is still warm obviously

These temps aren't worrying, with normal 24/7 use they won't go about 70 degrees. I only pushed them hard to make a claim for a spot in this thread
