Looking for tips on boosting your i5 2500K to i5-7500K?
I'm totally new to sandy bridge overclocking, hoping that someone here could help guide me. Here are my system specs: Cpu: i 5 2500k Gpu: Zotac 1050 ti OC Mobo: Biostar TP67B+ Ram: Teamgroup Elite ddr3 2x4gb 1600mhz Cpu cooler: Deepcool ice edge 200T (will change it out for a gammaxx 400 if needed) Psu: Corsair Cx550 Edited September 24, 2021 by MrP6k Photos didn't appear

The process remains consistent with today's chips. Gradually increase the core multiplier and core voltage, then perform stress tests to verify stability and prevent overheating. If your system freezes or stops working, adjust the voltage or modify the multiplier accordingly.
Back in the day, a safe voltage was around 1.52 volts, but I’m sure 1.6 volts will also be sufficient as long as you manage to keep the CPU cool. These parts typically reach about 5 gigahertz easily with a strong cooler and good hardware. However, that cooler is quite weak, so a gamma X400 might work if you’re comfortable handling temperatures near 90°C. I’m not very familiar with stressing newer chips since I’m using an LGA 775 board; this platform needs a lot of voltage and RAM. Still, I’d suggest turning off speedstep, turbo, and other power-saving features like C-State, and if possible, disable spread spectrum, set PL2 to 1, and push core current up to its maximum. I’m not sure what frequencies these i5 models can hit at stock voltage, but I’d try a multiplier of 1.25v for 42. If it doesn’t work, lower the number and see how it goes. Once you find your best setting, reduce it slightly and run stress tests using tools like Prime95. For cooling, use two wires and adapt the fan if needed—check the connector pins carefully. If you have a PCI slot, you can use a bracket from a case for better grounding. The middle pin usually carries 12 volts; connect ground to -12 and power to either 5 or 12 volts. Make sure you understand the pinout before connecting. I’ve seen some guides that might help clarify things. If you need visuals, just let me know!
This part of the setup is just a minor detail about the fan's design. The connector has three pins, with the power pin behind the ground pin—just treat it as any standard 3-pin configuration. The small metal tabs show the back side of the connector; black means ground, red indicates power, and you probably don’t care about the color choices for looks. For the 17V fan, wire 14 connects to -12V and links to the ground wire. The black wire goes to 5V, which with the 12V from the ground gives you 17V total. I moved the black wire to yellow (+12V), so the sum is 24V. This fan runs at about 1.3A and sounds like a jet engine, so I won’t run it. The -12V stays within its safe limit of 1A.
