I7 5820k Overclocking Help
I'm just getting started with overclocking and need some guidance. Currently, many people are downloading ASUS realbench, which might be causing issues. My setup was at 4.5Ghz @ 1.3V, but it became unstable after the first boot. The most recent attempt failed, possibly because XMP is set above 2400Mhz on my RAM (3000Mhz). I'm using a multiplyer of 36 with a 125 cpu strap. Could you offer some advice? Also, is running 4Ghz @1.25V with CPU Z a suitable starting point?
1.25v is quite high for just a 4 Ghz boost. I currently run it at 1.11v at 4 Ghz.
It's better to try lowering the voltage if possible at 4 Ghz. Going to 1.3V is the recommended upper limit and helps prolong your CPU's lifespan.
Using RAM above 2400 Mhz also means you're overclocking your memory controller. Wait until you've achieved a stable CPU before setting it to 2400 Mhz.
For matching single-core performance with an i7-6700K, a 4.4GHz voltage recommendation is typically around 1.35V.
NoahBE1998:
I'm looking to align single core performance with the i7 6700k range. What voltage would be best for 4.4Ghz? The choice mainly depends on your chip and how it handles the draw. I wouldn't exceed 1.28V just to ensure the CPU lasts. You'll need to test it yourself. Set the CPU to 4.4Ghz and gradually increase the voltage until the chip stabilizes or you reach a safe limit.
I began at 1.28 and intend to decrease the voltage but my maximum is 1.285, is that typical?
No, generally a motherboard supports going up to 1.3v and some allow even higher, though they caution about risks.
1.3v is usually the maximum suggested value. But it's not a fixed limit you can ignore without risking CPU harm. Exceeding the standard could lead to damage. The danger increases with higher voltages. For long-term use, sticking to lower voltage makes sense. Upgrading occasionally won't be a big issue. I used my 3930k at 4.5 for around three years with about 1.36v static voltage, no speedstep or C1E settings.
I am currently at 4.5Ghz 1.25V. After running ASUS Real Bench for 15 minutes, I received a score around 90000+. However, I’m facing some problems. My PC appears to have a booting issue—it happened before, regardless of settings. About three minutes ago, I shut it down and restarted it. The BIOS screen appeared briefly with Q Code AE, but then nothing. It showed only a small blinking white hash in the top left. When I tried to boot again, everything worked fine. I’ve had similar issues before, but without a BIOS screen or codes like 94, b4, etc. What’s going on with my PC? Should I consider reseating the CPU?
