overclock i5 4690k to 4.5ghz using an msi motherboard
Someone could assist you with achieving an OC of 4.5ghz on your i5 4690k. You're currently reaching 4.3ghz at 1.26v and 4.4ghz around 1.29v, while others claim success at 1.25/26v. With a 240mm liquid cooler in your SilverStone RL06 Pro case, you're still facing challenges. Please seek advice on optimizing settings or cooling for better results.
I initially thought I could say this, "Silicon Lottery," because some chips perform better than others, so it's impossible to compare them perfectly—use them as a reference.
The VCore is the main factor; generally failing means you should add more VCore, though other adjustments can help too. You might want to tweak the ring ratio to boost stability, even if it sounds counterintuitive—some overclockers find better results by lowering the ring speed, while others do better with higher speeds.
Ring voltage also plays a role in stability; raising it increases heat, whereas reducing it can help the Vcore run cooler and give more headroom for the VCore.
Check your input voltage as well—when you need extra VCore power, you might also require a bit more input voltage to maintain stability. I keep around 0.500v above my VCore for consistency.
Some users claim they need more VCore when talking about bottlenecks, but hard freezes usually point to higher input or ring voltage needs. A few tweak here and there—like adjusting system agent voltage or analog/digital IO voltages—can help, though I’m not sure it’s worth it.
Reducing RAM speed, for example to 1333MHz with a 2T command rate just for testing, could be useful, but only until you hit a ceiling; it’s not better than keeping at 100MHz.
You can start by trying 1.35v at 4.5 and see if the system boots normally, though I wouldn’t risk going over 1.3v—there’s this tricky decision between 1.3v and 1.35v for long-term stability.
