Quick question about OC
Quick question about OC
Hi guys,
I have an i7 3770k on a gigabyte z77 motherboard.
I OCed my CPU to 4.2ghz and it works fine at 1.2v (not the ideal setting).
I use the Intel xtu benchmark to check temperatures, and it shows static voltages around 75°C with a Vcore set in BIOS.
Recently, my processor runs at 1.2 on idle as well, which isn’t what I want.
To fix this, I adjusted the dynamic VID (offset) to match the same voltage (+0.075), but now the max temperature during benchmark reached 85°C—10°C higher than before.
Why is it getting hotter even though the voltage stays the same? Should I try reducing the offset or should I let it run static instead?
Same temperature with 0.000... Static voltage keeps everything below 1.2v and benchmarks fail. Now it runs fine with lower dynamic voltage but temperatures are higher? Something is wrong. Should I try using a minus offset now? Also, my load line calibration is set to auto.
EDIT: Got stable at -0.010, failed at -0.015. More stress testing shows temps similar to static vcore settings.
Also, when I OCed, I adjusted x42 multiplier, whether turbo boost is on or off doesn't matter. The only way I could hit 4.3ghz was by setting static vcore to 1.290 and LLC to extreme. But during benchmarking my temps reached 90°C, which is too high and performance gain was minimal, so I went back.
I haven't tried this offset voltage yet. Or should I set OC to turbo boost x43 for all cores instead of just a basic multiplier? Would that make a difference?
Any tips? I've read many articles suggesting max OC in air for this CPU and motherboard, around 4.7ghz, but 4.4ghz is actually achievable. For me it's around 4.2.
Are you really tracking the CPU voltage? It seems you think you can achieve a more stable voltage with an offset compared to static. That's unclear. My 3570K also runs at 4.2GHz.
I'm keeping track using hardware. It's working fine with -0.010.
