Inquiries about boosting 4790K performance
You're asking about stability when scaling all cores versus single core. At 4.8GHz all-core and 4.9GHz single core, stability depends on voltage and thermal management. If temps stay under control, increasing to 4.9GHz all-core at the same voltage is likely safe, especially with good cooling. For temperatures around 82°C during heavy workloads, voltage adjustments become crucial. Regarding RAM, higher speeds at lower voltages can improve stability but may increase power draw. Cache overclocking isn't typically recommended unless you're targeting specific performance gains. If you're aiming for maximum stability, balancing voltage, cooling, and workload is key.
Core stability varies from one processor to another, even if a single core can reach 4.9 GHz at specific voltages. Every CPU operates within its own boundaries. For safe operation, 1.35 V is typically the upper limit for continuous use when temperatures remain stable, making your 82°C a bit high but still acceptable. RAM voltage also plays a role in stability, though the gap between 1600 MHz at 1.5 V and 1866 MHz at 1.65 V is usually negligible unless memory performance is pushed to its limit. Cache settings can stay enabled automatically unless you prefer manual adjustment later. To achieve optimal stability, it’s wiser to reduce your maximum clock speed slightly rather than risking performance at the peak.
Your system now runs smoothly at 4.8GHz and 1.275V after adjusting the settings. The changes you made helped stabilize performance. Regarding your questions: enabling ASUS Multicore Enhancement can improve stability when overclocking, but it may also introduce instability if not configured carefully. Running Prime95 95 with AVX disabled and testing at lower voltages like 1.26V adds another layer of safety. It’s a good practice to monitor performance closely during these adjustments.
Turning off ASUS Multicore Enhancement was the correct choice—it typically only increases heat without much benefit. A stable 4.8GHz at 1.275V works well. Using Prime95 with AVX disabled is acceptable for testing, but you might also try RealBench or stress-test with typical games. If it performs okay under load, you're in the right range.
It's just a simulated boost. You won't be able to handle every task, so it's mainly for testing. Games often use AVX, for example.
1.35v is the highest safe setting I found for Haswell. I set mine to 4.8 cores and 4.5 gigabytes of RAM with 16GB storage.
