Testing/Stressing/ Benching utilities... Which to use???

Hello friends,

What utilities do you recommend to run to test/stress the memory and CPU?

1. I know for memory you use Memtest+, correct? How many passes would you run which indicate memory is ok?

2. What about the CPU? Prime95? How long would you run Prime95 which would indicate the CPU or Overclock in good? In other suggested programs for CPU stressing/testing?

Thank you for you input!

1. Yes, Memtest+ is one of the best if not THE best utility to test your memory. The number of passes for RAM stability testing is very subjective while some may do 1, others do 10, 50 passes. Some people even do overnight testing. Personally, to be able to complete 5 successful error free pases is more than enough. 😛

2. While there might be tons of programs to test CPU stability to test with, they should be taken with a grain of salt. Once again, there isn't a established time to run these. Pretty much like RAM stability, it's subjective. But if you must, some other useful programs besides Prime95 are Intel Burn Test and LINX. Run them for a 1 to 2 hours just to ease conscience lol. Just don't waste your life running them for days. Take that time instead to enjoy your system. 😉 The best stability test is using your computer normally.

memtest86+ as per the guide in my sig.

Stress tests are good to test your cooling and not much else. Sad to say this, but all they prove is that your system can pass that particular stress test for that period of time. No certainty that the next time your run the test it will pass. And we have heaps of threads of people crying my system passed 12 hours of Prime and then failed in WOW after 10 minutes. I kid you not.

If your system does the things you need it to do and does not fall over, fail or BSOD. Your system is stable.

One of the most demanding things your system will do is resume from sleep. Open heaps of applications that are memory heavy, have about 30 tabs open in your browser and put your system to sleep. If after a couple of hours it wakes no problem and all is good then mate you have a stable system.

Respect goes to those folks who are able to run Prime or any of similar stress tests for days on end at the lowest voltages possible. That is a skill all on its own an done I do respect. That is their thing, just like benching, gaming or what ever is other folks thing.
To help us help you - please provide as much information about your system and the problem as possible.

I totally agree. I have never used Prime, Linx etc to test the stability of an OC. I've lost count of the number of times I've heard people say they ran Prime for 12+ hours only to have the system crash after gaming for a few minutes.

After I set up an overclock, I run Aida64 for an hour. It's the closest stress test to real world usage that I've come across and I've been doing this for a lot of years (way back when it was called Everest) If my system can handle an hour of Aida64 it can handle everything I do with no WHEA logger warnings (which too many people ignore or don't know about)

Thestress tests are good for showing you what your max CPU temp is at any given clock and what voltage your CPU is using to get there.

I use Prime for maybe 15 minutes to see if everything is OK....then i get on and use the PC normally to see if it's really stable......

I will endorse Aida64 as a good stability tool for sure.

So it sounds like you guys are saying that the best program/utility to test the stability of a CPU is AIDA64, is that correct?
So its better than Prime95, Linx, Cinebench and others?

No Sir .. scroll back .. AIDA64 it is said is a great 'tool' ... however ..
you will see the very best .. It bares saying again .. the 'very best' way
to test is as HiViz suggests ... to see if your system is 'stable'.

Any test, imho, proves but one thing ... it tests well .. BUT .. but is a Huge Word ..
for 'Real World' use ??? The 'Sleep Test' reigns Supreme.

Please. Read the OC stickys on the forum ... it's all about how you ROG ourBrother and
for 'what' purpose.c.
