I thought I had a stable of 4.7 at 1.26v, but it turns out my 8700k can't reach 4.5ghz there... so what's going on? This is strange. I've seen it at 4.4ghz again at that speed. It's really annoying.

What else do you need? Please include a motherboard and power supply, and the 8700k should reach 4.7ghz stock. You may wish to revise any strong language in your message before a moderator handles it.

8700k 4.4ghz Full core, 1.26v (1.280 full load) LLC 6. This model was sourced from 4.7 all-core 1.26v LLC6 because it nearly crashed my PC during a GTAV turn in a corner. I've run OCCT large, medium data, and AIDA for two hours each without any problems. Running stress tests with full options is not possible due to overheating. Realbench crashes even with default settings at 4.4ghz 1.25v; everything else is fine, so I'm uncertain.

Maximus X Formula (latest BIOS 2102)

EVGA GQ 1000watt 80plus gold

3000mhz tridentz 16-18-18-38 1.35v

VCCIO 1.1

VCCSA 1.1

SVID Disabled

BCLK Adaptive Voltage Disabled

Ring Down Bin Auto (x41)

VRM Spectrum Disabled

BCLK Spectrum Disabled (just turned it off, possibly a slight performance boost, maybe just a placebo)

C-States Auto

Speedstep Disabled

Long duration power limit 4095

Short duration power limit 4095

Something I can't remember: 255.75d

Samsung 970 Evo 500gb

Toshiba 7200 RPM + 16gb intel optane (couldn't afford another NVMe M.2 1Tb)

Currently searching for PCIE spread spectrum, MCP PCIE spread spectrum, SATA spread spectrum, and LDT spread spectrum. I found a guide from 2008, so I'm unsure if these features are still relevant, but the explanations help. I might be missing important settings above. All power adjustment options remain auto, and the VRMS temperature throttling is active. Temperatures never exceed 63°C according to hwinfo. It seems I either overlooked a key setting or have a defective chip. I can't even reach 4.5 at 1.26v or get an LLC that pushes it to 1.28v under full load. Crashes occur in Rebel Galaxy Outlaw of All Games.
