Top programs for evaluating overclock stability.
Top programs for evaluating overclock stability.
For CPU I torture test P95 which I believe is the optimal program for it.
But GPUs are not that straightforward. I performed a benchmark and my OC appears stable, yet in games it can crash. Is there any tool that can clearly confirm if my OC is reliable?
Side note (that is longer than the actual post): Occasionally when I start my PC, the BIOS displays an Overclocking Failed message that resolves after rebooting. Does this indicate a problem with my CPU or the XMP profile on my RAM? I don't think GPU OC settings are linked to your BIOS since I use afterburner. Likewise, this might be connected, but the PC also occasionally fails to power up from sleep—BIOS monitor shows a 40 and the screen shows nothing. I have to restart if this occurs.
Problems with P95.
1. Many users stick to the older version to avoid harming their CPU.
2. Why bother proving stability when tests exclude the instruction sets found in newer P95 versions and modern software? It’s like testing your SUV’s off-road ability by driving on the highway in Miami.
3. P95 forces your CPU to handle sequential single tasks, which doesn’t match today’s multi-tasking needs. I’ve seen 24-hour stable OCs fail the multitasking benchmark in RoG Real Bench.
4. P95 artificially restricts your PC by showing voltage/temperature limits you’ll never experience again. Now if you built your PC for benchmarks and want your name on the web...
Issues with P95.
1. Many users stick to the older release to avoid harming their CPU.
2. The value of proving your OC stability is questionable if tests exclude the instruction sets found in newer P95 versions and current software. It’s similar to assessing your SUV’s off-road capability by driving on the highway in Miami.
3. P95 forces the CPU to handle sequential single tasks, which doesn’t accurately represent today’s multi-tasking conditions. I’ve seen 24-hour stable OCs fail the multitasking benchmark in RoG Real Bench.
4. P95 artificially restricts performance by displaying voltage and temperature limits that your PC will never experience again. If you designed your system for benchmarks and posted on OC Leader Boards, that’s acceptable; but if you built it for running applications, then an application-based test like RoG RB will impose more stress than any collection of apps. Therefore, a 4.8 OC limited by temperatures under P95 might actually be a 4.9 or 5.0 OC under RoG RB.
5. The GPU situation adds another layer. I first run Furmark to gauge the effect on GPU and coolant temperatures, as well as stabilization time. Then I perform 3D mark and Unigine tests, since they’re quicker but ultimately depend on the specific game.
I have five profiles saved in MSI AB…
a) Maximum stable core (stock memory)
b) Maximum stable memory (stock core)
These help identify if a game is struggling due to core or memory issues.
c) Best core/memory combination that doesn’t yield the highest OCs but the best FPS.
d) A noticeable drop from the previous results where certain games struggle.
e) A more significant drop for titles named “Battlefield.”
Realbench performs better, offering a wider range of realistic tests.
For light load CPU testing: Realbench for one hour
For heavy load CPU testing: OCCT for one hour
For GPU stability testing: That's challenging...there isn't a single best solution for GPU stability. I run FS Ultra, graphics test 1 and 2, looping them for an hour...if it succeeds, it's generally satisfactory. Usually...
