Just would like to know if you guys feel that 20 passes of Intel Burn Test 2.4 would be enough to consider my overlock stable and pretty much bulletproof. I've run over 25 benchmarks at these settings and it hasn't given me any problems. I've had this current machine since July but just now got around to tinkering with it and I am happy with the performance.

Cinebench 10 Single Core = 3,876 Multi Core = 13,751 OpenGL =7,716
Cinebench 11 CPU =3.73 OpenGL = 39.11
Everest CPU Queen = 22,672
Everest Photoworxx = 20,620
Everest CPU Zlib = 82,289
Super Pi 1.5 = 14.734 to 1 Million
WPrime = 13.046 to 32 Million
Fritz Chessmark = 18.09 Relative & 8680 Kilonodes
3DMark 2005 = 20578
3DMark 2006 = 16815
Sandra Drystone = 52.72 GIPS
Sandra Whetstone = 43.26 GLOPS
Sandra Multicore Efficiency = 18.45 GB/Sec
 
The thing about overclocking is stability is measured in statistics. We don't know exactly how stable an overclock is until we see the day that it doesn't pass the test. On my rig, I run LinX literally every night for the past six months (because electricity is free here) and I've encountered a few tests that froze and crashed, even though the conditions are the same. But given all the times it did pass, I can say that the overclock is about 99% stable. In brief, you can never get your system to be "bulletproof" because we can't statistically quantify how stable a system is. I'm sure that no system is 100% stable unless they ran the tests 24/7 from the day it was built. So, if you passed 25 tests and you feel arbitrarily that the system is at least 95% stable, then you needn't worry.
 
If I can play my games for hours on end, it's stable enough for me.
 
Thank you to all of you who share your experiences with overclocking and cooling your hardware. I forgot to put up my temperatures during the Intel Burn Test. Highest temperature recorded from Core Temp was 58C.
 
Nice job. You should be able to do 3.2 without changing any settings in your bios. Your cpu/mobo combo should do 4.0 with proper cooling. I say crank that mutha up.
 
Those quads overclock well. Your overclock is mild, you shouldn't worry about stability at all. You can easily go higher. I got my Q6600 to 2.8 GHz with no effort.

58 is your load temp, right??
 
i'd consider 50 passes more of a stability test than only 20. i have had the burn test fail on me after 25+ passes.

i also recommend using prime95 for testing also. ive been completely stable with intel burn test but failed prime. its a good mix of stability testing imo.
 
What cpu, mobo, RAM, and cooling are you using?

Maybe the combo you're using is what I need to upgrade to.

Did your Prime95 failure occur after 50 successful passes of IBT? I've experienced the same Prime95 failure after 20 good IBT passes. I'm trying to see if there's a way I can go back to using IBT for final stability testing, since it takes less time.
 
I'm satisfied with 25 passes of LINX and 2-3 hours of OCCT. Then I'll convert a Bluray rip overnight with X264 and if it completes it I'm satisfied. I know some people prefer to run 1500 LINX passes but that's just ridiculous imo.
 
Hi guys sorry I haven't been back to respond to you all! I have tried so many different configurations of bus speed and memory and upping the cpu voltage and ram voltage it won't boot at anything past where I have it now. Nothing will boot. I have only taken the cpu voltage from 1.175 to 1.200 nothing higher. Any suggestions to get this thing to 3.6-3.8 would be great since I am really confident that I have the cooling to keep it running at those speeds but it won't boot at anything past 377 x 8.5 @ 3.2 and 452.5 x 2 memory @ 905!!!!
 
I got my cpu to 3.4 which is great but I had to drop the memory back to 800 and up the voltage from 1.8 to 2.0 in order to get it to pass Intel Burn Test High. It made 5 successful passes with the core temps reporting 63/63/61/61 C. Very happy but I see of no way to get it to 3.6-3.8 and certainly 4.0 will be impossible. I've tried everything but it won't boot at anything above where I have it now. But I'm very happy with it @ 3.4 and if it stays stable that's good enough for me. I have no clue how you guys are getting those higher speeds. I've tried every setting and I can't get any better than this.
 
I can hit 3.2GHz on my old Q9450 starting from default settings and changing only one variable.

:p

I completely agree with you on both counts. I've had prime show errors when IBT did not and I've also had IBT show errors after 20 runs. IBT is good but not the end all be all it's also unreliable. You can do twenty runs then start it back up and fail in five is you are just mildly unstable as where if you fail prime in a half hour and run it again with the same settings it will error out at the same time into the test that it did before which really helps for tweaking.

Most ram doesn't overclock very well if at all. I find overclocking your ram to not be at all worth it since it's easy to kill and hard to really get stable when overclocking. Most chips are binned very tightly.

It's too bad there's not a 100% reliable way to determine if your overclock is 100% reliable. I had a C2D @ 4ghz that was rock solid in every CPU stress I threw at it, but would blue screen in some games. The chip ended up frying. After a year of that it became unstable even at stock speeds (was a voltage issue, not temperature, as 1.3625 is apparently the maximum you can run those things at safely)

Not really sure where I was going with that. I guess I wouldn't consider 20 runs of JUST IBT "stable." You need to do a whole gamut of tests on it, including running 3dmark on loop if you really want peace of mind.
 
I recently started playing with dropping my voltage on my E8400, went from 1.32 to 1.28. When I tried 1.26x volts it passed a bunch of Linpack runs just fine but after a few rounds of COD4 it hard locked on me. Sure stability testing programs work, but they only go so far as to determining true long-term and system-wide stability.
 
If you place more memory in the system you can use custom settings allowing the benchmark to run for longer periods of time before it takes a breather and starts all over.This places greater stress on cpu and could raise temps even higher.If statisfied with current tests results use machine as you please.OCCT and IntelBurn use same Linpack.

edit:Most posters here consider a 24hr the least time to fully gauge pass/fail testing

I started Prime 95 this morning when I left for work at 4:50am and it was purring right along when I got home at 2:15pm. Almost 9.5 hours and highest temperature recorded by Speedfan for CPU was 63C and the cores were 63/63/61/61 C and motherboard temperature highest was 100.4. Gonna put the gaming screws to it tonight with Crysis, Fear, Stalker and Clearsky, Dirt 2, Half Life 2, Resident Evil 5 and whole slew of other games to test the stability further as you guys suggested. Thanks for all the responses this has been very informattive.

nice
 
I ran Prime 95 for 9 hours while I was at work yesterday, 10 passes of high stress Intel Burn and every single benchmark I have which is over 25 of them. Not single burp from it. Running fantastic and I'm happy with the results. Played Crysis for 2 hours this morning and it's just running as fantastic as can be. I will be getting a Six Core Intel at the end of the year so I'm looking forward to the 4.2-4.4 type of speeds that they are getting out of them. I'm going to stop trying to OC this thing any further but I sure do appreciate all the help you guys have offered. Have fun and take care!!!
 
When running IntelBurn test, what settings to run? I had previously tested with standard but once in a while I would get BSOD. I re-tested with maximum setting and I had to increase my vcore. I need to check if I get BSOD in the future.
My default multiplier is 10, in order to OC I increase it to 12 and manually modify vcore. Instead of OC'ing 20%, I OC 10% by changing multiplier from 10 to 11. Previously I also manually adjusted vcore but today I left vcore in "AUTO" and it passed stress test. Is it okay to leave vcore in "AUTO" ?
