High-end OC system from 2013
High-end OC system from 2013
I'm adjusting how I phrase this. Here are your points reworded:
1. Is there a distinction between physically connecting the CPU to 125V and simply setting the clock speed to 125?
2. My temperatures seem normal during the stress test (77-81°C), but the package reads 87-90°C. What should I focus on?
3. Can I reduce idle temperatures? Is it typical for a CPU to run around 4.6 GHz even when not in use?
4. Why would turning off the liquid cooling fan help stability? Won't that hurt performance?
Update: After about 20 minutes of stress testing, the system crashed.
Strap 125 indicates the CPU and RAM operate at 125BCLK while the rest stays at 100BCLK. Setting 127.875BCLK manually restarts everything normally except at around 102.3BCLK, which should function as usual. At approximately 105.2BCLK with a 35 multiplier, it should keep most components stable. For 135BCLK with a 34 multiplier, expect around 108.4BCLK or 135.5BCLK at 35 multi for smooth operation. I’m unsure about 135BCLK but it might work depending on temperature and package. Ignore the power supply voltage; just enable C steps and mostly aim to reduce idle power draw. Generally, around 1.4V with a lower voltage drop is better—transient effects matter. If you set the max voltage to 1.35V instead of the full 1.35V, it helps avoid crashes even when dropping from 1.4V to 1.35V. Send photos of the burner, BIOS settings, voltages, and RAM timings if possible.
I can adjust the CPU strap in 100, 125, and 160 settings; manual selection isn't possible. However, I can modify the BCLK manually. Regarding RAM, I believe I've already tried everything to get it working. I reduced timings, raised DRAM voltage to 1.8, increased VTT and VCCSA voltages. Tried all options for stability at 2666, but it's still not reliable. Also attempted 2333, but it didn't work. I'll share my settings today or tomorrow.
It seems you're adjusting auto settings on a device. You're considering higher clock speeds like 135.5 or 145 with specific multipliers, but you're open to trying lower ones if you prefer. It's good to keep your current preferences safe by saving them in a profile. Avoid random changes since they often fail. Understanding the chip and its specs is essential—Hynix 4Gbit ICs usually handle around 1.65V at that speed for CL11. Share bios details, timing info, voltages, and screenshots of the burner and CPU-Z to help identify the exact model and confirm it's a Hynix part.
