My 4Ghz OC is stable with 12hrs small fft prime95. Is also stable on IBT 10passes at vhigh stress and is also stable with 2 hours linpack. max temps are 75c load.

Why then will it not pass OCCT, I get an error after about 30mins. Its very frustrating, how stable is stable and is occt a better indicator or not..?
 
OCCT is another, even more extreme, stability tester. I'd be quite happy if it passes 12 hours of Prime.

Apparently something like 40% of stock graphics cards fail the OCCT Graphics burn test.

You can get obsessed with stability testing....
 
Yeah you got to look at it this way, prime95 stress's the CPU what 95%?? for 12 hours straight, when else when using ure pc will you ever stress it more than that and for that amount of time?? Answer, never! If it passes Prime you have nothing to worry about

I would suggest that he uses the blend test for prime, as my system will pass hour after hour on small fft's but won't on blend ( im still tweaking it so its more stable for blend test).

Trust me, my mate, if your prime95 is passed after 12 hours, it more than enough to stable your pc. Don't worry about OCCT. But, question is would you re-edit video encoding or playing gaming for more than 6 hours in a single day ?

If no, then you got nothing to worry about. You're safer after 12 hours passed anyway. :) Enjoy your day. Make sure you passed 6 hours of blend test on prime95.

I agree with this guy, Prime95 Blend Test for 8 or more hours is better than Small FFT's when testing for stability..

I use a mix of LinX (20 passes using all available RAM), P95 Blend overnight, several loops of 3d Mark Vantage, and also play my games for several hours, if it doesn't crash with any of this, I class that as stable..

Although everyone is different when it comes to checking for stability.. some people I know will only do 5 passes of IBT/LinX, and 1 hour of Prime95 Blend, this IMO isn't enough to check for a stable o/c...
 
I've been having problems with blend, but have had to change to different memory timings and 191x21 instead of 200x20. upshot is vcore is lower.

I've got a bit more tweaking to do then I'll go for the 6 hour blend.
 
Yeah that is what I found, I tested right up to 1.35v for 20 x 200 and it still wasn't stable, but when I tried 21 x 191 I got the Vcore down to 1.264v and it was perfectly stable..

But now I have a brand new processor, so I will have to go through all that tweaking again to find stable settings.. oh the joys of o/cing!!! :D

My 200x20 was stable on everything except blend with a vcore of 1.25v

ibt, smallfft, linpack the lot, but p95blend would fail on one or more cores after 15mins.

aaaagggggghhhhh, makes me mental.

I have been using IBT, see the original post.

I got stable now on OCCT and 2hrs of Prime95blend. I'm going to leave it running blend overnight to make sure, but I think thats it.

Sorry mate, didn't see that there, just so used to seeing 'Intel Burn Test' rather than 'IBT' lol all these acronyms, flipping computers are like acronym hell :p
 
Hope you get it stable with P95 Blend mate.. if it is stable with everything else, then I can't see why Blend Test isn't..

I am having some trouble with my new chip.. I can't seem to get the darn thing stable @ 4GHz :(

Do you want me to take a photo of my bios setting of my perfect stable since installing H50 last month for you to get stable 4Ghz ? If yes, just let me know.

Done prime95 (blend) for 12 hours all passed, done IBT, done linx, done linpack, done OCCT and done memtest (all successful) and stable.

Make sure your motherboard (gigabyte ex58-ud5) got 5 blue lights (next to memory ram) and nothing elses (no yellow, green or red light) as it mean stable overclocked and stable voltages.

I would like to see how you have your BIOS set bulldog, to see if it can help me get this dog of a chip stable @ 4GHz...

Out of curiousity guys, are the chips that come with the o/ced bundles retail or OEM???

mine is come with bundles retail (every set of parts is in the box - none of it are OEM) ok, sure I will get a photo of my bios setting. My cpu are come in the box with intel retail fan stock.
 
I am starting to suspect I have been given a processor that wasn't able to make the 4GHz o/c for one of these bundles, because I have been here since just after tea time tonight trying to get this dog stable at 4GHz, using loads of different BIOS settings, and nothing is working for me..

I get BSOD after only about 30 seconds of LinX.. the longest it has ran for is 2 passes before I got a BSOD..

And it is the same stop code each time 0x00000101... I have played with Vcore right up to 1.3500v, and I have also tested QPI right up to 1.45v, and IOH Core up to 1.25v, but nothing I do will give me a stable o/c...

Maybe I am just being paranoid, but the chip I got as a replacement was definitely installed in a mobo as I checked the contact points on the underside of the CPU when I took it out of the box, and there were pin marks from where it had been installed in a mobo.. my last chip never had any such marks on it...

I am absolutely gutted tbh.. I wish that I had tested my old processor out with this TRUE first before I returned it, as I think it was the bracket for my old Zalman HSF that was causing the issues with only 4GB of RAM being detected in my rig.. because when the techs tested my old CPU it worked fine for them.. and I know that I could get 4GHz without any hassles with that chip...

As for your BIOS settings bulldog, there is no way in hell I would get 4GHz with those settings!!!

You have a cherry chip there.. I am curious as to why you dont have your RAM running @ 1528MHz, you do have 1600MHz RAM right?

Why don't you have the mem multi @ 8x and your uncore multi set to 16x???

Seems a little strange having 1600MHz RAM underclocked to 1146MHz... if your RAM is only 1333MHz then ignore what I have just said!!! :P

::edit::

Love the monitor BTW!!! :D
 
Could you let me see the RAM timing screens in Advanced DRAM Features, you know the Advanced RAM timings, and also a look in the Advanced Voltage Control as well if you don't mind?

Oh, and also Uncore & QPI Features, Advanced Clock Control, and Advanced CPU Features as well please!!! :D

Hey DavyBoy, I have the same batch as yours and I would say it is an average chip, I was able to get 4GHz 1.30v, this chip doesn't like high qpi/vtt voltage, I lose stability if I use 1.335v, here is my full settings:
