However, almost nothing at all will ever reach IBT levels. Some applications such as games with substantial amounts of software physics may reach Prime95 load levels. This means that IBT may fail on commercial CPUs that are running at stock settings simply because Intel doesn't test them to that extent. Unfortunately, the Linpack benchmark was designed for supercomputers (hence the floating point part, for modeling continuous phenomenon) so it really pushes desktops to the limit, far beyond what any application will do. IBT will easily drive load temps up to 20 degrees higher than Prime95, this is well known and is a defining feature of the program. IBT is generally regarded as being far more aggressive in the short term, which makes it great for testing ultimate stability. IntelBurnTest is an efficient software that is recommended by many Windows PC users. They are different in that IBT uses Linpack (solving linear equations) while Prime95 calculates Mersene Primes. IntelBurnTest is a Benchmarking application like SpaceSniffer, AS SSD, and NZXT CAM from IntelBurnTest Team. I run it for 8+ hours overnight, and then I know it's stableĪs long as it's not throwing up errors whilst your testing, you should be happy.īoth IBT and Prime95 are similar in that they stress floating point arithmetic and memory subsystems.
Intel burn test full#
Personally I use Prime 95, and small ffts only (this will stress only CPU and cache) the blend test won't get it to full load. Each poster will have a preference but they both do the same thing - put your CPU under full load to test for stability. Well, different horses for different courses. Will any application ever exceed the stress put under it by prime95? If so, will it ever reach the levels of intelburntest? As I'm not willing to overclock more if it's likely that it will reach similar temperatures to the IBT ones.
IntelBurnTest pushes temperatures around 83 degrees doing 20 runs of a high stress test, and after an hour, Prime95 gets temps around 67 degrees on the blend test. I'm currently OCed at 4.2GHz (1.18v Core Voltage) on my 4670k, and I've tried running both programs. I was wondering on the difference between intelburntest and prime95 for stress testing.
