Overclocking on asus h97-plus
Overclocking on asus h97-plus
According to my understanding, Asus has permitted overclocking on the h97 plus motherboard. The auto overclock functions properly, reaching up to 4.5 ghz with a core voltage of 1.276 in cpu-z. However, when I try to manually overclock, the system fails to boot or triggers a BSOD. I'm seeking some assistance to identify the issue. Thanks!
Yeah, 1.4V is quite high. Keep in mind that higher voltage generates more heat. You have a large cooler, but it has its limits. A chemist's tip for staying under 1.3V is solid. For someone new to OC, I’d suggest keeping it at 1.25V or lower, especially if you’re still learning. Also, achieving 4.7 GHz on Haswell largely depends on the quality of your specific chip (often called the silicon lottery).
The 4.5 GHz you observed during auto OC is a boosted result that varies based on CPU load and active cores. It reached around 4.5 with one core and likely around 4.3 with two cores, and about 4.2 with three or more. This kind of configuration is achievable on a Z board but not typically on an H board.
Try 1.25V and 44...
I have a system with an i5-4690k processor, a Noctua NH-D15 cooler, 16 GB of RAM, a GTX 970 graphics card with 4 GB of VRAM, and an ASUS H97 Plus motherboard.
Understand that the H97 BIOS likely has certain restrictions. You won't have the detailed adjustments available on a Z97 board. What parameters are you currently applying? VCore, CPU multiplier, CPU cache multiplier, cache voltage, BCLK, and so on. The CPU cache is often called "ring."
I'm completely new to overclocking, so please understand my lack of knowledge. The only adjustments I made were setting the multiplier to 47, keeping the bus speed at 99.98 mhz, and increasing the voltage from 1.25v to 1.4v. I managed to boot in and test at 1.4v, but it seems quite high.

For someone just starting out, I'd suggest 1.25V or lower, especially while learning.

Try setting the voltage to 1.25V and a CPU multiple of 44. Also, keep an eye on your CPU cache speed. By default, your board tries to match the CPU's clock speed for the cache, which increases heat. I’d cap the cache speed at a maximum of 40x if supported. Run Prime95 with FFT on a small board for roughly four hours to verify stability.
I'm cautious with that board, really. It does have many nice features, but it's designed for advanced users only. If you're unsure about using it properly, you risk harming your CPU. Better options would be something like an Asus Z97 board, an ASRock Z97 Extreme4, or an MSI Z97 Gaming board. Keep in mind that CPU OCing is more of a hobby than a practical need. Unless you're doing heavy calculations on the CPU, it won't significantly boost performance.
