Issue with PC failing to start following minor overclock adjustments.
Issue with PC failing to start following minor overclock adjustments.
Hello,
my computer fails to boot after I push the CPU overclock beyond 3.8GHz (starting from a base of 3.6GHz). I still have access to BIOS to adjust the multiplier. The situation with RAM is stable at 3200MHz (base 2933MHz), but combining it with the 3.8GHz CPU causes instability, sometimes preventing boot. BCLK remains unchanged; I kept both CPU and RAM multipliers at their default settings and set BCLK to 110MHz, but it still didn’t start.
I left the CPU voltage at auto (around 1.4V) and raised the RAM voltage from 1.2V to 1.3V. My graphics card also behaves differently—people online can easily overclock it to 2250MHz, but I can’t exceed 2150MHz without the screen going black. I increased the voltage by 0.1V and increased power consumption limits by 50%.
My question is: what’s the issue?
Specs:
CPU – AMD Ryzen 5 1600X
RAM – HyperX Fury Black 2x8GB DDR4
Graphics card – XFX Radeon RX 590 Fatboy
PSU – iTek Redbox FM 700W
Mainboard – Gigabyte B450M DS3H
What kind of motherboard do you have? It's possible the board lacks sufficient VRM to support stable CPU overclocking. Consider adjusting the RAM voltage to 1.35V and lowering the CPU core voltage to 1.325V. Avoid changing the BCLK value, as this might affect boot stability and PCIe lanes, memory connections, etc. Keep it unchanged at 100MHz. The graphics card should perform adequately. Most importantly, monitor temperatures closely. The system is likely to crash if the CPU temperature reaches 70°C with this overclock profile. AMD components tend to heat up quickly, and higher temperatures during overclocking can cause instability in OC'd chips.
Begin here - https://forums. It's recommended to increase one part at a time (CPU, RAM, BCLK, GPU, etc.) The era of overclocking BCLK beyond 105Mhz is gone. Many boards lose stability above 102Mhz.
The motherboard is suitable for overclocking, but overheating could cause issues with both the CPU and GPU. High temperatures may prevent successful overclocking. As mentioned earlier, reset your BCLK to 100MHz. Altering it further risks system instability. Give it a try, and as alceryes suggested, experiment with one part at a time until you achieve a consistent configuration.
For the GPU, online comparisons aren't reliable since each card varies. An OC of 150Mhz equates to 600Mhz due to x4 scaling, and your GPU memory operates around 8600Mhz, which is considered average. The exact figure also relies on the type of RAM your GPU uses; Samsung tends to overclock more. You can check this information in GPUZ.
Regarding your PSU, it's not a reliable brand unless it's from Seasonic, EVGA, or Corsair. It seems to lack a single +12v line.
Low-end motherboards generally struggle with overclocking. I didn't find any details about your motherboard's VRMs. I own an ASRock AB350 Pro4 with 1800X, but I can't overclock the CPU because the VRMs aren't strong enough to deliver sufficient voltage. This makes overclocking unstable.
