Multiplier stuck at 45
Multiplier stuck at 45
Hello,
I recently installed a PC with an i5-6600k and water cooling. As expected, I began overclocking. The CPU only reached a maximum of 50 degrees while running at 4.5 GHz, so I decided to push it further.
The problem is: when I set the multiplier above 45 (with a base clock of 100 MHz), it doesn’t go beyond that. The motherboard applies the setting, but the multiplier stays capped at 45 during stress. I’ve also experimented with higher voltages, up to 1.48.
Any suggestions?
auto voltage tends to become too aggressive, so it's usually best to set it manually. You won't see a big performance boost from just another 200mhz; it depends on how long it takes to reach stable at 4.7ghz, which might not be worth the effort. My settings will go higher than 4.7ghz, but I won't bother with all the work if the benefits aren't worth it.
I don't think 1.48v is a good choice for a 6600k, as it requires 1.32v to achieve 4.7ghz.
As mcnumpty23 mentioned, 1.48v isn't ideal. For clocks above 4.5ghz, you might need to boost the voltage input as well, not just the core voltage. It's unclear why you didn't encounter a BSOD instead of missing the exact multiplier. If your motherboard supports overclocking enhancements in BIOS, consider turning them on.
I've checked all the BIOS settings and even raised the clock to 4.7, but benchmarks still show lower scores than at 4.5. The motherboard also reached 1.48v when auto was selected, which seemed like a suitable voltage for 4.5, but I adjusted it back to 1.3v now. Should I wait and stick with 4.5?
