Can H5 Ultimate Overclock?
Can H5 Ultimate Overclock?
I’m planning to purchase a Cryorig H5 Ultimate and want it to run smoothly at 4.2 GHz across all cores. If my cooler can support that speed, I aim for temperatures below 80-70°C. My budget allows a CPU cooler around $60 USD. Would an H7 cooler perform better? I don’t mind the appearance of Noctua parts, but I haven’t decided to overclock yet—maybe later.

You have an unlocked CPU, a Z-series mobo, and look to be getting decent cooler... You, at some point, should OC. No question. If you like, you can see how it goes at stock and if you reach a point down the road where a core is at 100% utilization you can see if you can push it above 4.7 on all cores or at least hit that.
Yes, but not much. The H5 performs better than the 7. At 4.7 on all cores at 1.26v with no avx offset, gaming temps stay around 60C. OCCT stress tests show med/large sets reaching the 70s, while small sets overheat. Adding an avx offset could help, but your VRMs seem fine. For significant performance gains, consider a Cryorig R1, Dark Rock Pro 3/4, or a subpar Noctua.
Yes, but the results are limited. The H5 performs better than the 7. I’m at 4.7 across all cores at 1.26v with no avx offset. Gaming temperatures stay around 60C, while OCCT stress tests for medium or large sets reach the 70s. Smaller setups tend to overheat. You might improve performance by adding an avx offset, but your VRMs seem less effective than others’. For significant overclocking, a Cryorig R1, Dark Rock Pro 3/4, or a subpar Noctua would be better options. Would you consider overclocking to 4.2 on your current setup?
4.2 is an underclock... it turbos to 4.7 on a couple cores all by itself.
Edit: unless it’s overheating, the lowest it reaches under load is 4.3ghz:

I think I’ll avoid overclocking just yet?
You have an unlocked CPU, a Z-series motherboard, and expect to get a decent cooler... You should consider overclocking. No doubt about it. If you're interested, you can test it out at stock settings and see if you can maintain a speed above 4.7 on all cores or reach that level.
