3570k - 4.4ghz Temps
3570k - 4.4ghz Temps
Hello everyone,
I have an i5 3570k running at 4.4ghz with the Asrock z77 Extreme 4 Mobo cooler. The offset is +0.005v and Turbo Boost is +0.004v at LLC level 2 (75%). With Prime 95, I see about 85°C average CPUZ, which means the voltage is around 1.280v.
Most reviews I've read suggest this voltage is about 10°C lower than what I'm experiencing with similar settings. I’m wondering if my thermal paste pea method might not be working well or if I should reapply it.
Interesting too—my ambient temperatures are lower than the ones mentioned in other reviews.
Also, why is my voltage so high at 1.280v with such a small offset and extra boost?
Best,
Cameron.

Prime95 isn't a genuine benchmark, nor is IBT.
Consider testing with OCCT which employs more typical commands.

Download the AIDA64 trial and pair it with HWMonitor. Arrange them on your desktop together.

Regarding Prime95, general claims don't hold up for either of you.
The problem lies with the specific version details.
It's important to note that running Prime95 beyond version 26.6 is not advised due to excessive CPU strain using AVX instructions.
For accuracy, there are no issues with Prime95 before AVX version 26.6.
Version 26.6...
Feedback is provided on a public trial environment. In certain situations, your outcomes might differ. I wouldn't be overly concerned. Prime95 isn't an accurate benchmark, and IBT isn't either. Consider using OCCT for better results.
Prime95 is an intense synthetic tool designed to push your system to its limits. Download the AIDA64 trial version and pair it with HWMonitor, placing them on your desktop for easy comparison. For optimal results during overclocking, manually configure your desired frequency and core voltage—avoid using turbo boost if you're dealing with temperature problems. Lower your LLC to 50% and begin overclocking at stock settings until temperatures stabilize. Once stable, attempt higher frequencies. Do not aim for maximum overclock in a single attempt. I don’t know your motherboard or BIOS details, but the general approach remains consistent. When overclocking, start with a CPU core voltage around 1.2350v for a 4.4Ghz processor. If the overclock doesn’t succeed, increase the core voltage to 1.2600v and retry. Should temperatures remain acceptable, raise the multiplier for 4.5GHz and perform a stress test. If the overclock still fails, boost the core voltage to 1.3v. Avoid exceeding 1.4v, and if you hit a limit, drop the frequency to your last successful setting—this is your maximum overclock. It’s all about repeated adjustments until you reach the point where progress stops, which is often described as hitting a "wall"—no matter what you try, you won’t surpass it.
Do you believe using offset mode at lower voltage when idle isn't beneficial? If not, I'll stick to fixed mode and a constant voltage, but what settings should I use for turbo boost? Should I disable it or keep it enabled? Also, does setting fixed mode automatically disable it? And regarding the LLC 75% fine for fixed mode—what does that mean?
Offer isn't really effective at higher frequencies. I just use the multiplier when OCing. Turn off turbo boost and begin with LLC at 50%. If your CPU has Current Capability, set it to 120%. You're aiming for peak performance, so disable C1E sleep states if you have them.
My guide recommends the following settings:
Offset Mode: CPU will consume minimal voltage and speed during idle, whenever you idle. (Even when browsing counts as idle.)
Enhanced Halt State (C1E): Active
CPU C3 State Support: Off
CPU C6 State Support: Off
Package C State Support: Off
Fixed Mode: CPU maintains full voltage and speed continuously, even during idle.
Enhanced Halt State (C1E): Active
CPU C3 State Support: Active
CPU C6 State Support: Active
Package C State Support: Automatically enabled
Also, why choose LLC 3 at 50% instead of 75%, and why can't I disable Turbo Boost for some reason?
It seems the choice depends on personal preference regarding sleep modes. If you're concerned about your electricity bill, keep it running. It functions mainly as a power-saving tool during idle times. Also, verify that performance mode is enabled in your Windows power plan—it should resolve any turbo issues.
I usually notice my system runs faster without it.
Setting the LLC value too high can harm performance when heavy tasks are needed. I start at 50% and adjust as necessary.

Guys, Regarding Prime95, general claims don't hold up. The problem lies with the specific version. It's not advisable to run Prime95 after 26.6 due to unrealistic CPU demands using "AVX" instructions. For accuracy, note that Prime95 pre-AVX version 26.6 is perfectly fine. Version 26.6 Small FFTs is ideal for thermal testing as it provides a consistent 100% workload, closely matching Intel's Thermal Design Power (TDP) requirements.
