first attempt at i7 6700k overclocking, prime95 discussion
Hello guys,
by the start of the got myself new PC rig, with i7 6700k Skylake and Noctua NH-U12S pro as cooler, running with ASUS Z170 PRO GAMING.
lately trying to OC, for a first time, so i better to ask arround, when it comes to stress testing and most importantly which temperatures i should keep eye on.
currently sitting on 4,4 GHz, voltage on 1,35
after like 20 min of stress testing with Prime95, my temperatures are mostly arround 65 - 72 °C. but what worries me a bit are those max. temperatures which prime95 showing: 88 - 92 °C. those max temperatures jumps out for a split of a second, literraly, noticed it like 3 times during those 20 min of testing.
so i start to wonder, should i focus on max measured values, or the "average" ones?
tryed to play Fallout 4 with this setup aswell, after 2 hours of gaming, i havent passed 70°C on my GPU once.
so it seems like everything is fine to me, only those max. temperatures from Prime95 scares me a bit.
thnx
Take a glance at the intel temperature guide provided here. Running at 1.35v is close to the upper limit I'd prefer for continuous operation, overclocking mainly involves fine-tuning the vcore with the multiplier. A 4.4ghz boost isn't particularly high considering the voltage unless you've already pushed it to its limits. Opinions vary on what remains stable or suitable for stress testing. Asus rog realbench is a solid multicomponent stress test, covering CPU, memory, GPU, etc. If it holds up well, consider slightly lowering the vcore to around 1.33v and checking stability. For temperatures measured with p95 on the latest Intel CPUs, using v26.6 and small FFTs works best (see the article above)...
Synthetic stress tests, particularly for the CPU, put more pressure on the processor than it would in real situations. As long as your temperatures stay below 75°C during CPU-intensive gameplay, your temperatures are acceptable.
yes, that's exactly what I was thinking ^^
i plan to play a bit more gaming to confirm
thanks
Check out the intel temperature guide here. Running at 1.35v is close to the upper limit I’d prefer for continuous operation, overclocking mainly involves fine-tuning the vcore with the multiplier. A 4.4ghz boost isn’t particularly high considering the voltage unless you’ve already pushed it to its limits. Opinions vary on what’s stable or suitable for stress testing. Asus rog realbench is a solid multicomponent stress test, evaluating CPU, memory, GPU, etc. If it holds up, consider slightly lowering the vcore to around 1.33v and see if stability remains. For temperatures measured with p95 on newer Intel CPUs, using v26.6 and small FFTs works better. (Refer to the article above). This approach applies a steady-state load, so temperatures should remain consistent. A 10-minute p95 run is sufficient; longer durations aren’t necessary. In general, I monitor thermals with realtemp, run realbench, perform p95 v26.6, Intel burn test, and check Intel’s xtU. It’s common for a CPU to pass one test but fail another—this is largely a matter of personal preference. I view p95 more as a thermal stress test than a stability check because it focuses on a narrow range. When doing stress tests, it’s wise to keep an eye on temperatures and avoid leaving it unattended, particularly for p95 or IBT tests. The goal of these thermal tests is to push the CPU beyond its usual workload in regular programs, simulating a worst-case scenario safely.
Thanks for the reply, appreciated. I haven’t attempted to push my CPU to its maximum yet—just taking it one step at a time, being a real rookie. Honestly, around 100MHz probably isn’t that significant. Still, it’s good to see how far your hardware can go. I’ll try version 26.6 as you suggested, especially during gaming sessions.
PS: Sorry for posting in the wrong section—I didn’t notice this when I wrote the topic. Obviously. 😛
