Prime95, AIDA64, intel burn-in test

[MsTrMind]

So can someone explain to me which stresstest is the 'best'?

 

Also, why is prime not good for haswell?

[Samdb]

Use them all, they are all good choice.

I too want to know why is Prime95 not good for Haswell. I have used Prime95 for all my other CPU overclocks and was planning on using it when I receive my Haswell chip.

[Vitalius]

I would simply guess that the reason Prime95 is not good for Haswells is because they tend to get hot enough as it is. Then again, I would also assume that any of those tests you listed would stress Haswell to 100% anyway. 

Hmm, no idea. VRM problems? *shrugs*

Indeed, at the start (well the early start) of haswell, Prime95 was not verified if it was doing a real stresstest and checking everything. But now I want to know why people are still recommending not to use it :-)

Well the p95 temperatures are actually 5 degrees lower than the AIDA64 one's, didn't try the intel burn test thingy.

Doesn't haswell do some sort of throttling that renders P95 useless as a stress test?  As I don't own a haswell CPU I can't say from first hand knowledge, but I seem to remember a video from Linus or Logan or someone from around launch time that said something along those lines.

Well, I don't know if I understand you correctly, but while running P95, the cpu load stays at 100% and the clockspeed & voltage also stays at what I dialed in...

[teeejay]

I mostly use Aida64

[Eyal]

I like linpack the most...

Currently I am using Asus'es Realbench 1.1

FRom what I have read, it does the job at a more realistic level. Temperatures are closer to real-world applications (still about 10°C higher to give headroom). From what I have read 5 passes from their stresstest would result in a 99.99% stable cpu, when used in average applications, like gaming, browsing and renderring.

The stresstest is actually renderring.

You can also do a "benchmark"-like stresstest, which consists of image editing, video encoding and multitasking.

I Think that from now on I will recommend this to people. In the end, every pc will crash no matter how much hours of prime, ibt or aida you throw at it. If you run it for 24 hours without errors, it is possible that 24h and 1 minute will let it crash.

According to JJ (Asus rep for those that may not know), Prime95 can damage even Ivy Bridge CPUs, yet most say that's untrue, so who knows.

Didn't know that :-s Bye Bye Prime!

I would trust JJ over other people honestly. Linus and the other types of reps like him know a looot more about this than we do. Remember, they have to go to those meetings/conferences/things to be briefed on the specifics of a product before they can review/get sent a sample. 

Like Linus knowing that CPU wafers are circular. I thought that was awesome to know. 

Just saying, people like Linus and JJ get more detailed "behind the scenes" and specific info than most other people, so yeah.

It doesn't take a special person to know that. Anyone can find out.

I actually would trust JJ more on this than Linus. 

I have the feeling that Linus isn't that in to overclocking anymore... Agreed, he would still know over-9000 times more about pc's than I do.

It is actually JJ's job to make sure their stuff works, and that he can explain how their stuff works. It is from his video that I learned about RealBench, and so far it is impressing me pretty good

Thank you! Now I actually know why it is bad :p

[MsTrMind]

I wrote a paper about how CPU's are produced, and the evolution of nanotechnology :p

Shortest damn thing ever! 

Appart that they are made from sand, are circular and verry glossy you allmost can't find any information about the manufacturing process :-p

So can someone explain to me which stresstest is the 'best'?

When stress testing Haswell cpus you only have two options, to stress test your cpu properly. Your best bet is to use the Intel Extreme Tuning Utility, your only other option is Aida64.

 

Currently Only these two programs are validated for Haswell.

 

 

 

Aida64- Validated for Haswell instruction sets. WILL OVERVOLT YOUR CPU if your Vcore parameters are set incorrectly

 

Intel burn test- DO NOT USE . NOT Validated for Haswell Instruction sets.WILL OVERVOLT YOUR CPU if your Vcore parameters are set incorrectly.

 

Prime95-DO NOT USE . NOT Validated for Haswell Instruction sets.WILL OVERVOLT YOUR CPU if your Vcore parameters are set incorrectly.

 

 

 

Intel Extreme Tuning Utility- First party software Developed by Intel, updated and validated for Haswell. Does Not cause unnecessary over volting under ANY setting.

This video is the main reason i chose an ASUS motherboard and felt confident enough to start overclocking. Much love and appreciation goes out to JJ from ASUS AKA Asusilluminati which is his handle on this forum.

Considering he is a rep from THE Asus, then it might be true. Plus, prime95 puts a huge huge load on your cpu.

Ty for this info, I'll use intel extreme tuning utility for now on.

But one thing, linus used aida64 for his haswell overclocking guide
