s about Intel I7 4770k
Hello, I have an i7 4770k-Msi z87-gd 45 gaming setup with 2x 4GB Corsair Vengeance DDR3 1600 mhz and a PSU that is Evga TX 850m.
I used this build for about 4-5 months, but the stock cooler didn't work well due to high temperatures. Now I bought an Xigmatek Gaia II and my temperatures are normal. I started overclocking today. My chips have problems with overclocking, so I set multiplier clocks to 45 and voltage to 1.200, and it works fine. The HWMonitor shows idle temps between 45-47. I tested it with AIDA64 system stability, and temperatures reached up to 90, causing throttling (around %4-5). The main issue is the high temperatures. When I run Cinebench r15, the CPU gets stuck without any blue screen or other issues—just needs a reset.
It also works at 44 clock ratio, but I can only push it to 42 to avoid getting stuck and remain stable during tests. I’m wondering if there’s anything I can do to go above 4.2.
Sorry for my poor English.
You might want to adjust some BIOS settings in addition to increasing voltage and multiplier. You likely didn’t win the silicon lottery like me. I had a 3770k and considered a 4.4ghz EZ, but only reached stable at 4.2ghz with acceptable temperatures. Going up to 4.3 wasn’t worth it because the heat was too much for such small gains. My motherboard is a z77 gigabyte, which makes it one of the best options for that CPU.
Things you could try include:
Turning off CPU EIST and C states
Setting Performance enhance to extreme (the name varies by manufacturer)
Toggling Turbo power limit ON/OFF
Adjusting DDR voltage to Extreme
I understand the lottery on my 2x 2600k back. I managed to get both 4.7-4.8 clocks easily. I doubt this time.
I looked up all the information about bios, but only EIST and C state are available—both are disabled.
I set clocks to 4.4, voltage is 1.250 ring ratio 43, ring voltage 1.200. It passed cinebech r 15 and prime95 for 30 minutes on aida64 during system stability testing. Should I use 4.2 or keep it at 4.4? I’m asking because during pubg sessions with 2-3 hour play times, the temps don’t rise as high on Aida64.
I frequently wonder if you've refreshed the MB bios.
This is usually overlooked, but those changes can significantly boost performance.
I don't run any complex tasks requiring stability, as my operations aren't tied to critical work. My performance isn't affected by freezing since I'm not handling serious applications. What benchmarks are you referring to?
In Cinebench r15 Hwmonitor displays a maximum temperature of 86 degrees.
It seems a bit high for that benchmark. If it isn’t throttling, fine. Just avoid going above 75-80 degrees Celsius to ensure long-term performance. Monitor the voltage in BIOS when testing; if it rises above your BIOS setting, check the hardware monitor. If needed, lower it to x42 and stop there. You might have already verified the thermal paste and cooler placement. Also, look at your fan settings in BIOS—make sure they’re set to Normal mode instead of SILENT, as silent mode can raise temperatures slightly due to slower speeds. Don’t worry if your CPU stays under 75 degrees during normal operation.
It shows throttling on an AIDA64 stability test, but temperatures stay between 90-92 during the test. Throttling levels were around 3-4. I used the MSI control center and set all fans to spin at 100%. During games like CS:GO and PUBG, temperatures never exceeded 75. I believe the issue lies with setting the 42 clock on that CPU, as it wasn't throttling on AIDA64.
