the i7 3770k is having trouble reaching over 4.2ghz
The system features an intel i7 3770k processor (h60 2013 with two sp120's in push-pull configuration, staying under 80°C). The motherboard is an asrock extreme 4. RAM includes a hyperx fury 16gb ddr3 at 1600mhz (rated at 1866mhz but tested lower for OC). The gpu is an nvidia gtx 1080ti. At 4.2ghz it runs smoothly with a load level 5 -0.50v offset. If I increase the voltage beyond this, I encounter BSODs with errors like "KMODE_EXPECTATION_NOT_HANDLEED", "nvlddmkm.sys", "KERNEL_SECURITY_CHECK_FAILURE" and "DRIVER_IRQL_NOT_LESS_OR_EQUAL". Even though I've adjusted voltage, timings, and vtt settings, problems persist. I've managed to run benchmarks like fire strike (3dmark) without issues, but prime95 or intel burn test cause crashes within 5 minutes, though temperatures never exceed 85°C. Anyone have suggestions?
I'm testing i7-3770k at 4.6ghz with 1.32V Vcore using Deepcool Captain 360. During stress tests I reached 70°C. I'm using an MSI Seahawk GTX 1080 and have Asus P8Z77-LK motherboard. The performance depends on the specific board I'm using. This chip tends to get very hot; better cooling than a single 120mm radiator would help.
Intel Core i7-3770K Ivy Bridge Quad-Core at 3.5GHz (3.9GHz Turbo) with LGA 1155 design consumes 77W. The maximum performance reaches 9.9GHz, but stability decreases beyond that threshold.
80C appears quite expensive to me. What adjustments have you made to the Vcore?
4745454b seems like a high value. How much did you raise the Vcore? At full load, 80c wouldn't be considered high—around 50-60c for gaming and 20-30c for idle. I've been using offsets instead of fixed values for Ivybridge, which seems to be the best approach based on the guides I've read. With a level 5 load line at -0.05 on a 4.3ghz processor, I haven't encountered any problems yet, but I'm still aiming for 4.4ghz since the performance difference is quite noticeable despite the CPU limitations.

The performance depends on the motherboard you're using for overclocking. I'm using an Asus p8z77-lk board. A video I found helps me tune it closely to my setup: https://www.youtube.com/watch?v=wnH0luwrcfE. If I experiment further, I might push the CPU even higher, but currently it's stable. (Note: this chip gets very hot; better cooling than a single 120mm radiator is recommended.)
