i5 4690k OC Problem
i5 4690k OC Problem
I'm just starting out with overclocking and have been following some YouTube tutorials on the basics. When I became confident, I set an OC of 4.5ghz on my 4690k which was running at 1.278 volts. Early tests using small FTTs and blending on Prime95 showed temperatures that were manageable. The blended temps stayed around 70°C or slightly lower, while the smaller FTTs reached much higher in the 80s. I'm satisfied with these results because the stress test doesn't reflect real-world conditions on my CPU, and I believe I should be fine during normal daily use.
The initial clock speed looks good. However, after leaving Prime95 overnight and returning, I found it had crashed two and a half hours into my Beauty Sleep (after checking the crash logs).
Now I'm unsure what steps to take next to make this more stable. Should I reduce the overclock or increase the voltage? Any advice would be greatly appreciated. I'd really appreciate it if you could help me with any further information. Thanks.
The voltage is too low for that clock unless you possess a very good chip. Just gradually increase it until it stabilizes. Setting the clock to 4.4Ghz should make it more feasible. I can reach 4.4Ghz at 1.290.

Sure thing, I get it. Whenever I run into an issue, I just jump in. If I hit 1.3, I lower the clock to 4.4 and check what happens next. I don’t really want to keep running prime unless I have to solve some problems. I’ve been playing Arma all day today on the sessions above, and everything’s been fine.
The voltage needs to be increased gradually for stability, and setting the clock to 4.4Ghz should help. I reached 4.4Ghz at 1.290 successfully. Regarding the CPU running at 4.5Ghz continuously while it should have throttled before, that might indicate a power or thermal issue.
Usually the speed throttling is disabled during overclocking, which reduces efficiency in that way. It's a BIOS setting, and it could make the system more unstable, especially at higher overclocks where this issue tends to appear.
