Completed adjustments to my OC on the 4670k using an Evo 212 cooler. System is stable at 4.5 Ghz with peak temperatures around 75-80°C during Aida64 stress test. I adjusted Vcore to 1.31V and Cache to 1.25V for stability. Cache speed is set to 3.9Ghz. CPU VRM operates at 1.81V. This setup seems safe for a Haswell system. I’m seeing solid Geekbench scores—4050 single core and 13530 multi-core at 4.5 Ghz.

Also, figuring out how to fine-tune the voltage so it only overvolts the CPU when needed. Dynamic voltage helped during stress tests but didn’t lower it in regular use. I’m using a Z87 Asrock Extreme 3 as my MOBO.

Do you need assistance? Are there any specialists remaining who have worked on Haswell?
