Inspecting parts for short circuits (CPU, motherboard, GPU)
Inspecting parts for short circuits (CPU, motherboard, GPU)
Hi, your message is clear. You’re checking the stability of your components after a minor issue with a cryptocurrency miner. Here’s a concise summary:
1. Intel Pentium Gold G6400 (LGA 1200) – Resistance checks show VCC-VSS around 1.7Ω and VCC-VCC0 ~50Ω, which is much lower than the Xeon E5504 you compared. Over 11 years, this suggests the resistance hasn’t changed drastically—your CPU remains functional.
2. MSI Z490-A PRO – No shorts detected on both power and CPU connectors.
3. MSI GeForce RTX 3070 Gaming Z Trio – All connectors show no shorts.
You might want to test additional parameters like voltage stability, fan behavior, or thermal performance before finalizing your setup.
Welcome to the discussion boards! Please note that multimeters often measure higher voltages than what a CPU anticipates, which can damage the CPU in theory. However, this method usually provides little practical data. The safest way to confirm functionality is by connecting it to a motherboard and checking operation. If it fails, it won’t harm other parts.
If a short occurred on the motherboard, you’ll notice noticeable changes—like darkened or yellowed spots, blown capacitors, or no visible damage at all. Testing every surface mount becomes time-consuming. The most reliable test is assembling a working system with it and verifying it runs.
Should the GPU fail, expect a burnt mark on the board. The best test is connecting it to a stable power supply (like a 650W or 750W unit) and checking if video output appears. If it doesn’t work, it’s likely the power supply is faulty. Installing a suspect PSU is risky; it should never be used without proper precautions. Many defective PSUs only become problematic at higher loads, so you might need to replace several components or build a new setup with a fresh power source.
GPU operated smoothly after several hours in the furmark. The motherboard had two slots (one with a channel) that were faulty—booted only when the farthest slots from the CPU were used. The CPU seems fine; I recall having a similar HP prebuilt at work, but it refused to boot with it, suggesting a possible memory channel issue might also be present. Thanks for the advice!
