Why do people hate p95?

[xgn]

ofc it is possible...

Yea so its not going to break. I believe it when i see it. Also i use the latest version.

[SkywardKkalox]

I am pretty furious right now

P95 26.6 : http://windows-downloads-center.blogspot.co.uk/2011/04/prime95-266.html

use 1344k fft size  for testing cpu vcore

use 8k for cooling solution

800k for ram

864k whole system

if you are overclocking your cpu, you can probably run an hour of aida and crash within minutes with 1344k

i feel the p95 hate bandwagon is just stupid, gaining a bit of knowledge on fft sizes can mean you can test your system very effectively and using the right version can stop temperature issues on the newer avx versions

 

but, why do people hate prime ?

It had a problem back when haswell launched that killed the chips and so the hate continued.

[ITS-PARTY-TIME]

The fact that P95 uses AVX doesn't change my point?

Almost all people will use the latest version.

my bad i was talking about the newer versions using fpu (Floating Point Unit) which produces insane temps

[daniellearmouth]

I don't necessarily hate Prime95, but I don't use it.

 

I just stick to benchmarks and stress tests I'm familiar with: AIDA64, 3DMark, Cinebench, and an assortment of games like The Witcher 3, Total War: Shogun 2, and so on.

[0ld_Chicken]

I think that it's grand! Ever since I learned how to use the fft settings properly its been my favorite.

The main issue with Prime 95 is its effect on Haswell architectures. It would increase the voltage being applied to the CPU causing higher temperatures than what would've occurred. I don't like Furmark either because of the high stress it puts on the MOSFETs on the graphics card PCB. That's why AMD and NVIDIA cards throttle - they programmed them into the drivers to throttle whenever Furmark is running. Additionally, people have passed overclocks using Furmark but then would crash immediately in a gaming scenario.

 

My personal recommendation for stress testing video cards is Unigine Heaven/Valley, 3DMark Firestrike, and real games, including Minecraft if you're going to be playing that.

[LogicalDrm]

Like I said in previous thread. I think it as ancient software. There are others which don't have any issues with Intel chips regardless of version. While with P95 you keep saying that it needs to be run with certain settings and version to be reliable. Doesn't sound very user friendly to me. Another thing is that when I used it with Q6600, you were required to run it for 24-48h. Which is frigging long time when PC is located im from your bed.

So now I use mainly OCCT for CPUs and Kombustor for GPU. Though I haven't done OC to GPU in awhile so I don't know if Heaven/Valley would be better.

[Godlygamer23]

[..]Kombustor for GPU. Though I haven't done OC to GPU in awhile so I don't know if Heaven/Valley would be better.

Kombustor might have the same effect as Furmark. Throttling due to overloading the power delivery and giving a stability pass when games would crash, but I don't use either anymore.

[bcredeur97]

only reason I don't like it is because of heat. my cpu will be at 90+C whereas it never hits that for any other program...

It's a useful stress test for 5 minutes or so but after that not so much.

Boy, this again. I've been preaching for a very long time about Prime95 on this forum. Some people have learned, others will forever remain unchanged by facts. 

 

Prime95 killed CPU's because everyone expects their 4.8ghz OC's to be prime95 stable. Those same people got a very harsh physics lesson once they realized they were wrong, and lost their CPU's because of their arrogance and ability to let a few hundred mhz go for the sake of stability. Word spread around like cancer on OCN, and it was all it took for everyone and their mother to believe that Prime95 was a "CPU killer". Funny enough, I have never killed a single CPU running Prime95. I have used it since my Phenom II days, all the way up to my current Skylake build. I've used it on my FX 8320, my G3258, my brothers 4690k, etc. Never had a single CPU die. That is with me using the AVX/FMA3 versions too.

 

This next part is just my opinion, so let me get that disclaimer out of the way. Running prime95 without AVX is childs play. If you are afraid of your CPU getting hot, overclocking is probably not for you anyways. Now, newer Prime95 uses what is called FMA3, which comes from the same branch as AVX. Even with AVX disabled, you can still run FMA3, but to a slightly lesser extent. Is it hot? You bet! That's the point. Seeing if your OC can not only handle the pressure of heavy math, but to do so at high heat. I can assure you, if you can handle several hours of FMA3 heavy math, no normal use scenario will ever crash it.

 

People still claiming Prime95 is a Haswell killer should go and research FIVR and fully understand what it does, and how to handle their voltage settings. Maybe then they won't fry their CPU's under real stress.

26.6 still uses avx iirc

i recommend that because it doesnt use fpu (floating point unit)

and its the same with aida.. enable fpu and look at the temps shoot up

but 26.6 still gets it damn hot regardless

I do not want to hate it but since it has made CPUs literally explode I do not think it is the safest tool for people to use...

 

P95 should only be used by hardcore over-clockers who wants to really push their systems!

[Nena Trinity]

-snip-

Nope P95 has made CPUs explode but I am not aware what those people did to OC their CPUs!

No CPU has "exploded" using prime95. Your use of the word "literally" is not valid. Point me to one source where a CPU "exploded" from Prime95. You will not find one.

So you have never heard of the Pentium 4? It have exploded WITHOUT P95!

[MageTank]

So your source for Prime95 causing CPU's to explode, is to mention a CPU that exploded WITHOUT using Prime95? How many times must I tell you to stop with this spreading of misinformation? 90% of your posts on this forum are rumors or blatant lies trying to be passed off as truth. Until you start providing sources for your claims, you will never be taken seriously.

If a motherboard's BIOS pumps way too much voltage into a chip when running a supported instruction set, I don't think it has been tuned properly.

 

It's not like p95 is able to directly alter your CPU voltage...use manual voltage and tune it yourself if AVX is causing it to go too high!

 

My M5A99fx board at stock auto voltages pumped out ~200mv more voltage than necessary to be stable...is it a game developer's fault for making a game that got my chip hot at stock settings? No! The auto settings from the factory simply were not optimized, at all!

 

p95 doesn't kill CPUs...people that allow core voltage to skyrocket while stress testing kill CPUs. There is more to a safe overclock than setting a multiplier, base core voltage, and enabling an xmp profile!

 

I like p95 because in my limited experience, it will expose instability faster than any other test I've used.

This is the other problem I have with the anti Prime95 movement. People don't understand where the heat comes from. Everyone wants their hardware to run cool, but Heat is not always a bad thing. Heat can be a byproduct of efficiency. Prime95 is a VERY efficient program. Efficient in the sense that no resources are being wasted. Every core/thread being stressed to the fullest extent. FPU's being used when the OS would have otherwise put them to sleep under normal circumstances. 

 

Chances are, if your CPU is running cool during a stress test, it is probably because the stress test is not stressful enough (inefficient). Now, I am not going to dictate to people which stress test they should use, or fault them for using the stress test of their choice. Everyone is perfectly capable of deciding which is best for themselves, but I won't let them slander one stress test over another, when in all honesty, it is perfectly fine. 

 

The simple truth is, you wont see those 4.8-5.0ghz 4790k's completing a full 27 hour blend (again, takes 27 hours to complete every single FFT on blend) simply because that overclock is just too high for it to ever be stable, even with a legend class golden bin and high end liquid cooling. That's just the physics of it. Does that mean those 4.8-5.0ghz overclocks are unstable and invalid? No. I have seen plenty of very high end OC's fail Prime95, but go on to run every single game and normal consumer task and never crash once. Again, Stable, and Prime-Stable are two entirely different things in the overclocking community. 

 

Some people will prefer speed over absolute stability. To others, absolute stability always comes first. To each their own.

You never provide proof so provide some first then!

Ive always found that 1 hour of 1344k without crashes to be "stable" maybe not 100 percent, but it will never crash in real world usage.. i have yet to see an overclock that passed 1344k fail in anything real world

The Pentium 4 is known for exploding do I really need to prove something EVERYONE WHO LIVED AT THE TIME KNEW?!

you said it was unsafe... we are talking modern cpus here you know?

People will fight about litterally anything. Prime 95 vs something else, CX psu's vsu something else, Apple vs others, AMD vs Nvidia

 

Dont be surprised

[Nena Trinity]

It is still unsafe if you do not know what you are doing the CPU or motherboard will be fried!
